Use: as a cargo bike. Essence: a tricycle with two frames and a flywheel has an additional flywheel drive configured to interact with the main drive through electromagnetic control elements. 9 ill., 1 tab.

The invention relates to a cargo bicycle, a 2-seater tandem is known, to which a trolley is attached, such a design in urban environments is not convenient due to its storage and it is very difficult to climb hills with a load. The goal is to facilitate the design and possible storage at home and transportation of 150 kg of cargo at a speed of 30-35 km/h. This is achieved by the fact that the bicycle consists of two frames, parallel located, with solid wheels united by one axle, with inside on the right wheel there is a flywheel mounted on a swing bearing, which is pressed onto the axle rear wheels, but having separate drives consisting of sprockets of different diameters, increasing the rotation speed relative to the wheel several times; bearings are pressed onto the ends of the roller, onto which the ends of the frames are attached. The drive sprocket is also pressed onto the flywheel bearing, taking into account that the flywheel develops a peripheral speed of up to 700 m/s, and the wheels have a maximum speed of 12 m/s. When the flywheel assists the bicycle, especially when overcoming inclines, the flywheel drive sprocket has teeth on the end side. The right and left wheels are pressed onto a common shaft; the drive sprocket of the right wheel with teeth facing the flywheel teeth is mounted on it, to avoid sharp jerk when the flywheel is turned on, it is carried out due to the difference in the diameters of the clutch sprockets and the common shaft itself, which protects against a sharp jerk and does not allow an increase in the peripheral speed of the wheels. The bicycle is controlled by a cyclist sitting on the right wheel and has a common frame with the front wheel. The cyclist, sitting on the saddle of the left wheel, rotates the pedals with a driven sprocket, the shaft of which is fixed on the platform 28, the same cyclist, in order to increase power by taking kinetic energy from the flywheel, disconnects the current supplying the electromagnet 33 from the dynamo that rotates the front wheel, the spring expands and pushes the thrust washer, which is attached to the pipe, inside of which there is a common shaft 9. The other plastic end of the pipe is screwed into the drive sprocket of the right wheel, which moves along the spline to the right and the teeth of the drive sprockets mesh. To increase the peripheral speed, in addition to the driven sprocket, the flywheel drive also has intermediate sprockets of small and large diameters, mounted on one swing bearing, and the “gala” chain transmits rotation to the drive sprocket of the flywheel. Note: The intermediate sprocket bearing is mounted on a shaft attached to the frame. The flywheel drive is protected on top by a shield, and the sides are protected on one side by the right wheel, and on the other by a cargo box that is freely inserted between the wheels, its bottom is made of plastic, and a nylon mesh is attached around the perimeter, fixed at the top to the frame. The wheels, flywheel and frames are cast from cental containing 65% polyacene and 35% magnesium powder; such a polymer, in terms of density and elasticity, is capable of withstanding the full load of a cargo bike with a specific gravity P of 1.21 g/cm 3 . The approximate weight of the main parts is given in the table. In fig. 1 shows a side view of a 3-wheeled cargo bike; Fig.2 is the same, plan view; Fig. 3 is the same, end view; Fig.4 shows the drive sprocket wheel assembly with clutch teeth, end view; Fig. 5 is the same, wheel, side view; Fig. 6 shows the flywheel assembly, side view; Fig. 7 shows a washer pressed onto a flywheel bearing, side view; in Fig.8 left wheel, side view; Fig.9 shows a device for connecting or disconnecting the flywheel from transmitting energy to the wheels, side view. In Fig.1-9 the following designations are used: 1 rear right wheel, 2 rear left wheel, 3 front wheel, 4 flywheel, 5 cargo box, 6 swing bearings, 7 flywheel swing bearing, 8 flywheel drive sprocket, 9 rear wheel shaft, 10 flywheel drive sprocket, 11 flywheel drive intermediate sprockets, 12 right wheel driven sprocket, 13 left wheel driven sprocket, 14 drive sprocket of the right wheel, 15 drive sprocket of the left wheel, 16 Gala chain, 17 right frame, 18 thrust tube screwed into the drive sprocket of the right wheel, 19 feed spring for engaging the sprockets, 20 thrust washer compressing the spring, 21 left pedal wheels, 22 pedal of the right wheel, 23 washer mounted on the flywheel bearing, with engagement teeth, 24 teeth of the wheel drive sprocket, 25 engagement teeth of the flywheel assembly, 26 steering wheel, 27 holder for the left cyclist, 28 platform for attaching the holder and pedal roller, 29 nylon mesh, 30 bottom of the box, 31 drive from the thrust washer, 32 armature, 33 electromagnet freely sitting on the shaft, 34 electromagnet holding washers. A special feature of the invention is its lightness, the flywheel helps cyclists when overcoming climbs, and does not require liquid fuel, as do mopeds or motorcycles. At the end of transportation, the box is removed, folded and it is easy to find a place for storage, the left wheel is also separated from the right wheel, there is no analogue for such a bicycle yet. Cargo bike operation. A cyclist sitting on the right frame controls the bicycle, and the movement is carried out simultaneously by two cyclists by twisting pedals 21 and 22, thereby rotating sprockets 12 and 13, and sprocket 10 rotates intermediate sprockets 11 and 14, transmitting the goal of “Gala” rotation of sprocket 8, such The flywheel drive device creates a significant peripheral speed for it without affecting the speed of the rear wheels. The rotation of the flywheel is free until the cyclist sitting on the left frame turns on the current, which generates a dynamo rotated by the front wheel, from which the electromagnet 31 will attract the armature 32, and this will compress the spring 19 and at the same time attract the washer 20, which connected to a plastic tube, inside this tube there is a shaft connecting rear wheels, the other end of this tube is screwed into the drive sprocket of the right wheel, in this position the flywheel and the wheel are separated and each of them has its own peripheral speeds; when the electromagnet is de-energized, the spring straightens, moves the washer, which with its tube moves the air sprocket 16 of the right wheel along the splines, which has teeth towards the flywheel, while its teeth will go behind the teeth of the flywheel sprocket 8, which is why the flywheel will begin to transfer kinetic energy to the wheels, which, having different diameters of the clutch of the sprockets and the shaft 9 itself, will produce a sharp jerk, and the peripheral speed of the wheels will increase slightly. The flywheel drive is protected from above by a shield, and the sides are protected on one side by the right wheel, on the other by a cargo box, a nylon mesh is stretched around its perimeter, the wheels, flywheel and frames are cast from lightweight materials, including sectyl containing 65% polyacene and 35% magnesium powder, such a polymer is dense and elastic enough to withstand the full load of a cargo bike, the total weight without load will be a maximum of 20 kg. Economic result. The specified cargo bike design is intended for transportation of agricultural products. products from household plots and urban residents or small farmers, saving money on travel by commuter train or by bus, as well as saving money on the purchase of gasoline. Its peculiarity is that it does not require separate warehouse due to the fact that it can be easily disassembled and can be stored on a balcony or loggia.

CLAIM

TRI-WHEELED BICYCLE WITH TWO FRAMES AND A FLYWHEEL, containing wheels and a drive made in the form of a driven sprocket connected by means of a chain drive with a drive sprocket mounted on the wheel axis and an intermediate sprocket, and a flywheel freely mounted on the axis outside the wheel and connected to the shaft by means of a coupling , characterized in that it is equipped with a flywheel drive made in the form of a drive sprocket located on the flywheel bearing, a driven sprocket mounted on the axis of the driven sprocket, and an intermediate sprocket with electromagnetic control elements mounted on the wheel axis for interaction of the flywheel drive sprocket with the spring-loaded drive sprocket wheel mounted on splines.

Almost all bicycle drive designs have general disadvantage, reducing their efficiency. This defect consists in the uneconomical expenditure of muscular energy when changing efforts from one leg to another while the pedals pass through “dead spots” (vertical position of the connecting rods). Most of the muscular effort at this moment is directed towards the axis of rotation of the pedals and does not perform as much useful work, how much increases wear on the carriage bearings.

It’s not for nothing that cyclists move their cranks out of the vertical position before starting to move. As a result, the power stroke begins with a partial loss of muscular energy, which causes premature fatigue of the cyclist.

The proposed improvement in the bicycle drive eliminates this drawback, allowing lovers of long trips to ride in an economical mode, rationally using muscular energy, spending it almost like during normal walking. For this purpose, the drive design uses a device for interrupting the interaction of the connecting rods with the drive sprocket, which ensures free and rapid passage of the connecting rods with the sector pedals near the “dead spots” due to inertia. General form

The design of a bicycle drive with an inertial interrupting device is shown in Figure 1, where the connecting rods 1 (with pedals) mounted on the carriage shaft 2 have a movable (sliding) connection with the drive sprocket 3 due to the interaction of spikes made on the bushing 4, mounted on the right connecting rod, and diametrical grooves - on the drive sprocket 3. The grooves allow the connecting rods to quickly pass through the dead zone, and the 5-point flexure coil spring softens the shock at the end of them freewheel . As can be seen from the drive diagram,

constructive change

Stopper 6, made of soft wire and fixed to the drive sprocket by bending the ends on its jumper beams, prevents the spring from moving away from the plane of the spring sprocket when it is in a tense state during operation. Next, the right connecting rod 1 with the drive sprocket is fixed in the usual way on the shaft 2 of the bicycle carriage unit using a wedge 9. When installing the spring, one end of it is installed in a suitable hole on the drive sprocket, and the other bent end wraps around the connecting rod near the pedal.

To expand the adjustment of spring force 5, a number of holes are additionally drilled along the diameter of the wire on the drive sprocket to install the bent end of the spring into them.

The drive works as follows. In the initial period, for example, when installing the right foot on the right pedal, which is in the upper position, the connecting rods 1, together with the shaft 2 and bushing 4, rotate until the bushing pin interacts with the drive sprocket 3, while the spring 5 is compressed and creates a torque on the drive sprocket. After applying muscular force to the right pedal, the drive sprocket is rotated and the bicycle accelerates.

When the right pedal approaches the lowest position, the working interaction of the connecting rods (bushing pin) with the drive sprocket is interrupted by delaying the rotation of the connecting rods relative to the drive sprocket after reducing the force on the pedal due to the reverse action of the spring and the inertial movement of the bicycle. In this case, the spring supports the rotation of the sprocket and removes it from interaction with the connecting rods.

As a result, at the beginning of the next working cycle, the connecting rods move into the vertical position region with some reverse angular displacement relative to the drive sprocket, which ensures a free transition of the vertical position and the next accumulation of the spring for the left crank. Then the drive operation process is repeated. The free transition of the pedals to the extreme upper and lower positions eliminates the loss of muscular energy when changing cycles of their work, which increases the efficiency of the drive., which is similar to maintaining the rotation of the flywheel with an intermittent tangential force. The delay in the rotation of the connecting rods helps to compensate for the inertial forces acting on the cyclist’s legs in the area of ​​“dead spots” during their rapid rotational movement.

The efficiency and stability of the drive is influenced by the spring accumulation force, which is selected depending on the weight and physical fitness of the cyclist. If after the working stroke the connecting rods do not move away from the drive sprocket, then a more elastic spring must be installed. And vice versa, if for free pedal transition top position a noticeable muscular force is applied to it and during the working stroke there is no working interaction of the connecting rods with the drive sprocket - then the elasticity of the spring must be reduced.

This can be done by selecting the diameter of the spring wire. For normal operation of the drive, the amount of reverse movement of the cranks must be less than their initial angular displacement. Under such conditions in transition processes

operation, the initial torque on the drive sprocket is maintained, which further enhances the damping properties of the spring to smooth out peak loads during pushing rotation of the drive sprocket.

When learning to ride a bicycle with such a drive, the cyclist is required to pay certain attention to monitoring the uniform rotation of the drive sprocket with free play of the connecting rods. Upon acquiring certain skills, the uniform rotation of the drive sprocket and the amount of reverse movement of the connecting rods are maintained automatically and do not present any difficulties or discomfort.

Experimental sea trials over a distance of 3,500 km confirmed the efficiency and reliability of the drive. Compared to a conventional bicycle, fatigue on long trips is noticeably reduced, which expands the cyclist's capabilities.

The chief forester of the Duke of Baden-Württemberg, Karl Friedrich Christian Ludwig Freiherr Drais von Sauerbronn, 17851851, received a patent for a two-wheeled bicycle in 1817. After Dries drove his car 15 kilometers in an hour on July 12, 1817, the bicycle became fashionable. And then the inventors of the Old and New Worlds began to race to improve the two-wheeled “bone shaker.” By the end of the 19th century, when the bicycle already had modern forms, bicycle designers managed to obtain several tens of thousands of patents. However, this process, despite its seeming absurdity, continues now, in the 21st century. At the same time, not only curious bicycle models are patented, but also completely progressive machines, which have undeniable advantages compared to the canonical two-wheeled device for riding using muscular effort.

Two wheels = a lot!

Riding a unicycle was once popular in the circus, requiring considerable skill from the performers, since this design very unstable. Now, due to the growing popularity of extreme entertainment, at least every fifth young person has become an acrobat. In this regard, monopeds, exactly the same as in the circus, although with a saddle and sometimes with a handlebar, appeared on wide sale. And extreme sports enthusiasts use them for such entertainment as, for example, competitions to conquer the Eiffel Tower. Of course, they climb the steps, and not along the outside of the tower.

However, it turned out that it is quite possible to give significant stability to a single-wheeled structure and use it for travel by people who are not at all athletic and far from young. Inventor Oleg Makhankov equipped a serial bicycle wheel with four metal plates. Two of them are constantly parallel to the ground. The other two, thanks to hinges and spring suspension, change the angle of inclination depending on the terrain of the road, driving speed and body position of the rider. The wheel axle is attached to the upper parallel plate, and the saddle frame to the lower one. This leads to the fact that the center of gravity of the structure is significantly shifted downwards, and therefore acceptable stability is achieved. When riding over bumps, thanks to a well-thought-out shock absorption system, the rider, regardless of the terrain, moves strictly in a horizontal plane.



There is also a fundamentally different position of the cyclist relative to the wheel - he is inside, perched on a small seat, rotating the pedals and controlling the outlandish design using a regular steering wheel. The rolling of the outer wheel with a diameter of 1.74 meters is carried out by nylon rollers. The cyclist “climbs” onto the front of the wheel using pedals connected to friction transmission. This design is also stable due to its low center of gravity. True, problems arise when braking: at this moment it is necessary to lean back, because due to inertia the rider can spin so that he ends up with his feet up, head down. When does it happen? emergency braking, retractable “paws” with rollers at the ends are activated. They prevent tumbling.

Such bicycles are mass-produced in China. True, they were invented by the Brazilian Tito Lucas Ott. And he didn’t invent a bicycle, but a unicycle with an engine internal combustion. Not so long ago, his invention, the implementation of which many previously doubted, was used both directly - the production of gasoline monocycles was launched in the United States - and with the expectation of the strength of the leg muscles. And then the initiative was seized by the Chinese, whose total muscle strength is enormous, but with gasoline and engines it is much worse.

With a certain stretch, one can call the design created by the American Bruce MacLennan Blackwell a bicycle, since the inventor equipped a small wheel with a diameter of 25 centimeters with an electric motor powered by a battery. The unicycle has neither a saddle nor a steering wheel. A person simply stands on two footrests located on either side of the wheel and rides. Control is carried out by deflecting the body in right side. To increase speed you need to lean forward, to brake you need to lean back. The problem of increasing the stability of a unicycle is solved by using a high-speed gyroscope. It has been resolved to a sufficient extent, since Blackwell, not being a tightrope walker, has so far not only not broken a single bone, but also not suffered any bruises.

Minimalists

Due to big cities As the world suffers from congested transport arteries, the problem of creating compact folding bicycles has recently become urgent. You can use them to get to the nearest metro station, and then, transporting the bike underground, get to your place of work. In England, a bicycle was created that can be folded in 30 seconds and, most importantly, hidden in a suitcase so that the steering wheel and pedals do not stick out. So far, Londoners are not sweeping this invention off the shelves, but perceive it only as a game of a brilliant mind.

An even more compact bicycle was designed by Clive Sinclair, a famous inventor who once created the popular Spectrum computer. His bicycle, called A-Bike, fits into the case in twenty seconds. When disassembled, it looks like the letter A (hence the name A-Bike). With all that, this baby is capable of supporting a 120-kilogram rider and allows you to move at a speed of 24 km/h. The weight of the bike was reduced to 5 kilograms due to the fact that most of its parts are made of plastic.

Sinclair's model generated a competitive effect. Folding portable bicycles began to be produced in France, Japan and America. Undoubtedly, such a means of transportation would be very useful in Moscow, despite the fact that the capital’s government is frantically building more and more transport rings around the Kremlin.

The smallest and lightest bicycle was made by an electrician from Poland, Zbigniew Ruzhanek. It weighs only 1.5 kilograms. The diameter of the front wheel is 11, and the rear one is 13 millimeters. A bicycle is good for everyone, except that it has absolutely no practical use. Ruzhanek made it solely to get into the Guinness Book of Records. The brave electrician drove 5 meters on his flimsy device, became famous throughout the world, and then he calmed down.

Friends of Paradox

There are inventors who brilliantly prove that mechanics promises us many more wonderful discoveries. These include nuclear physicist Yuri Makarov. Having retired, he used his intellectual potential to invent fundamentally new bicycle designs. In one of his models, the pedals rotate... in reverse side! It would seem that the same work is being done, but other muscle groups, stronger ones, are involved in it. Therefore, on a Makarov bicycle you can develop higher speed with the same effort. Another model has a box installed automatic switching gears, and the bicycle chain is a Mobius strip, which allows you to significantly increase the efficiency of the mechanism. There is a “heavy truck” model, with which the retired inventor tows a minibus and transports 100-kilogram loads.

At the Moscow International Salon of Industry, Makarov was awarded the Big Gold Medal “Archimedes-99”. His bicycle was exhibited at the exhibition of future technology in Milan. That was the end of it. Domestic bicycle manufacturers categorically refused to introduce Yuri Alekseevich’s car into production, believing that this very future would not come in the present century.

Engineer from Barnaul Gennady Vasiliev received an even higher award for his bicycle Gold medal International Geneva Exhibition of Inventions in the “Mechanics” category. This award is especially valuable because 15 recent years No laureates were appointed in this category.



Vasiliev’s bicycle is capable of reaching a speed of 75 km/h. In this case, there is no need to turn the pedals; they perform linear reciprocating movements. The secret of such a high efficiency of the mechanism is that it uses the “spinning top principle”. Let us remember how, during the years of our golden childhood, we spun the top to exorbitant speeds; the top acquired the properties of a gyroscope. Such a transmission has long been known in mechanical engineering, and it is called a ball screw. Relatively speaking, it is a “loose” pair of screw and nut, the spaces between which are filled with balls. If you press on the screw from above, the nut begins to rotate. At the same time, the inventor did not blindly copy the well-known transmission, but modernized it, so it is quite possible to talk about the “Vasiliev transmission.”

In Geneva, the “new Kulibin” was hit with an avalanche of offers from foreign companies for cooperation. He liked the Belgian engineering concern. However, Vasiliev soon got the feeling that his partners intended, as they say in Russian business circles, to ditch him. And he returned home to introduce his miracle horse into Russian production. However, the homeland met Vasiliev unfriendly. For four years now he has been trying to find mutual understanding in various authorities.

And the bicycle of Fyodor Sychev from Naberezhnye Chelny allows you to climb the mountain without great physical effort. This is achieved through the use of a crank mechanism with a large lever. And he has exactly the same story with the introduction of the invention into production. It can be assumed that this is due to the fact that our country has a predominantly flat terrain. In the countries of Transcaucasia, and even more so in Nepal, it would not be worth it.

But Canadian bicycle manufacturers, the Ktrak Cycle company, have taken great care of cyclists. It is known that winter in Canada is no less snowy than, say, in Siberia. And riding a bike through snowdrifts and ice is not much fun. And then the witty Canadians replaced the front wheel with a ski, and the rear crawler drive. The design is quite simple and weighs the bike down by only two and a half kilograms. However, a bicycle improved in this way without any problems rides not only on snow, but also on sand, which is also not easy for ordinary “bikes.” The demand for the invention turned out to be such that already at the Interbike exhibition, where the new product was first presented to the public, there were many who wanted to purchase this system. The main value of the Ktrak package is that you don’t need to buy a new bike: you just need to convert your existing mountain bike. And in the spring you will put the wheels on it again, and, as if nothing had happened, you will drive along your favorite ravines and copses.

A very useful bicycle model was invented at the American University of Purdue University. A bicycle has two rear wheels, which when stationary are located at an angle to each other, connecting at the top and diverging at the bottom. Due to this, a stable tricycle is obtained, which a child or a “teapot” not trained to ride can easily sit on and begin pedaling. As the speed increases and the bicycle gains inertial stability, the rear wheels join together to form a single wheel. When stopping occurs reverse process the wheels at the bottom “spread out”.

There are eccentrics in the arena!

In this category we have only two bicycle-building wizards. But what kind!

Tim Pickens, president of the British company Orion Propulsion, engaged in developments in the field of rocket science, attached a jet engine, which is used to correct the orbit of satellites. Fortunately, he filled it with non-rocket fuel, which prevented it from flying under the clouds. The fearless Pickens used fuel oil as fuel, and therefore the thrust was only enough to accelerate Mr. Pickens to a speed of 100 km/h in five seconds.

And Kuban pensioner Evgeny Mikhailov uses horse traction to move the bicycle he designed in space. The procedure is as follows. Mikhailov places a specially trained horse “on the handle” of the bicycle, attaches pedals to its hooves, and the horse begins to turn them. And it turns so hard that the structure rushes along a country road at a speed of 70 km/h. The cyclist controls the car using the steering wheel and applies gas with the reins. There is a three-speed gearbox. But there are no brakes yet. Because the designer has no time for such trifles now. He got the idea to create a horse-drawn airplane using the same principle of operation. It remains not entirely clear how Kuban animal defenders view these experiments?

The invention relates to vehicles that accumulate energy in the flywheel. The bicycle has a drive connected to the drive wheel (2) and to the flywheel (8), which has a spring suspension (19) with the ability to press the flywheel (8) to the drive wheel (2). In this case, the drive wheel (2) with its flanges (6) is mounted on bearings (7) on the frame (1), and the flywheel (8) is installed on a double-lever pendulum (10) inside the drive wheel (2) with the possibility of pressing the flywheel (8) to inner surface of the rim (3) of the wheel (2). Technical solution is aimed at ensuring periodic, at short intervals, transfer of part of the accumulated energy from the flywheel to the drive wheel. 12 salary f-ly, 7 ill.

The invention relates to mechanical engineering and can be used on various vehicles, bicycles, and wheelchairs.

There are known vehicles in which mechanical energy is accumulated and then transmitted to the wheel vehicle. The recuperator has the form of a ribbon spring (RU 2097248, 1997). US 4,037,854, 1977, discloses a bicycle drive connected to a drive wheel and to a flywheel having a spring suspension with the ability to press the flywheel against the drive wheel. JP 08-169381, 1996 discloses a flywheel, parts of which are capable of pressing against the inner surface of the output link. US 2,588,681, 1951, discloses a drive in which a heavy ball is lifted by means of a lever inside a hollow cylinder and then tends to cause its rotation by means of its mass. Next, the hollow cylinder transmits rotation to the wheel inside which it is located.

Creation of engines, propulsors and other devices for obtaining non-traditional types Mechanical energy, its reproduction, accumulation and use are important areas in the development and improvement of dynamic, small-sized and affordable vehicles. In the proposed bicycle with an inertial propulsion device driven by human muscular force, or a drive motor, the working fluid, made in the form of a thin-walled cylindrical ring and located on the crosspiece, when rotated, creates and accumulates the kinetic energy of the moment of inertia of rotation of this working fluid. Part of the accumulated energy is periodically, at short intervals, transferred by the working fluid to the drive wheel of the bicycle and causes its forward movement.

The claimed bicycle has a drive connected to the drive wheel and to a flywheel having a spring suspension, with the ability to press the flywheel to the drive wheel, and is characterized by the fact that the drive wheel with its flanges is mounted on bearings on the frame of the vehicle, and the flywheel is mounted on a double-lever pendulum inside the drive wheels with the ability to press the flywheel to the inner surface of the wheel rim.

The flywheel, installed inside the drive wheel to form an inertial propulsion device, has a working body made in the form of a thin-walled cylindrical ring, mounted on a cross mounted on a shaft based on bearings in the pendulum arms.

A double-lever pendulum with some ends of the arms is mounted on bearings of the pedal axis, and at the other ends of the pendulum arms a shaft with a flywheel is mounted on bearings, which can be shifted relative to the axis of the pedals by a small angle.

The flywheel, by means of two springs, can be suspended, with the exception of the flywheel touching the inner surface of the drive wheel.

The inner surface of the wheel rim and the outer perimeter of the flywheel working fluid are coated with a friction compound.

The wheel consists of a rim, side discs with flanges under support bearings, while a sprocket with a freewheel is connected to one of the flanges.

There are two or more bicycle tires on a wheel rim.

When rotating the pedals, the possibility of simultaneous rotation of the wheel and flywheel;

When you press the pendulum and transfer part of the energy from the flywheel to the wheel, it is possible to rotate the wheel faster, without transferring force from the pedals to the wheel, because pedals provide rotation and unwinding of only the flywheel;

When rotating the pedals, it is possible to move with or without the use of an inertial propulsion device.

A motor may be installed which is coupled to the drive via a chain connected to the drive sprocket.

The steerable front wheel can be mounted on a stand in the frame hub, or the two steerable wheels can be paired and mounted on an axle with a stand at the rear of the bicycle, with the stand mounted in a hub on the frame, and a gear sector meshed on the stand below. with a gear sector of the steering shaft.

The seat can be swivel.

The brake pad, acting directly on the tires of the wheel, is mounted on a pin on the frame in the seat area and is connected to a lever to provide braking.

Frame 1 is welded, tubular section. The drive wheel 2 consists of a rim 3 with tires 4, side disks 5 with flanges 6 and bearings 7 and is installed in slots 5 of frame 1.

The inertial propulsion device consists of a flywheel 8, a shaft 9, a double-lever pendulum 10, a freewheel 11. The flywheel 8 includes a working body 13, made in the form of a thin-walled cylindrical ring, a cross 14 mounted on the shaft 9. The working body 13 is located on the perimeter of the flywheel cross 14 8, inside the drive wheel 2. A double-lever pendulum 10 at one end on bearings 45 is mounted on the axis 16 of pedals 17, at the other ends of the pendulum 10 is mounted on bearings 18, a shaft 9 with a flywheel 8. The pendulum 10 can rotate relative to the axis 16 at a small angle and is supported by springs 19 in a suspended position, excluding unauthorized contact of the flywheel 8 with the rim 3, since the axis of the shaft 9 is offset relative to the axis of the wheel 2.

The foot, muscular drive of the flywheel 8, located on one side of the wheel 2, includes a drive sprocket 20 mounted on the axis 16, a double sprocket 21 located on the pin 22 of the pendulum 10, and a sprocket 23 with a freewheel 11 mounted on the shaft 9, sprockets pairs are connected by 24 chains.

The front wheel 27 with steering wheel 28 is steerable, mounted on a rack 29 in the bushing 30 of frame 1, or two paired steering wheels steerable wheels 31, located at the rear of the bicycle on the axis 32, with a common rack 33 installed in the sleeve 34 on the frame 1, a gear sector 35 is fixed to the rack 33 from below, which is engaged with the gear sector 36 of the steering wheel 37, the steering wheel 37 is installed in the bushing 38 on the frame 1 .

The drive motor 39 is connected by a chain to the sprocket 26. The seat 41 is swivel. The brake pad 42 is installed on the pin 43 on the frame 1 near the seat 41 and connected to the lever 44; when braking, the pad 42 is pressed directly against the tires 4 of the wheel 2.

Operation of a bicycle with inertial propulsion. When the pedals 17 rotate, force is transmitted through sprockets 20, 21, 23, chain 24 and freewheel 11 to flywheel 8, at the same time through sprockets 25 and 26, chain and freewheel 12, force is transmitted to wheel 2, as a result the bicycle moves and spins flywheel 8, which accumulates the kinetic energy of the moment of inertia of rotation of the working fluid 13.

When you press the pendulum 10, the latter, together with the rotating flywheel 8, rotates at a small angle (Fig. 5-7), periodically, for a short period of time, presses the perimeter of the working fluid 13 of the flywheel 8 to the inner surface of the rim 3 of the wheel 2 at point A (on line AA ), the contacting surfaces of the working fluid 13 and the rim 3 are covered with a friction composition, part of the kinetic energy is transferred to the rim 3 of the wheel 2, a reaction force P of the rim 3 arises, which causes a force P d of the translational movement of the flywheel 8.

In addition, during the period of contact of the flywheel 8 with the rim 3 of the wheel 2 at point A (on line AA), the speeds of the mass points of the working fluid 13 change and an instantaneous center of rotation (ICR) of the working fluid 13 appears on the contact line AA, the speed of the ICR is zero, in this instant, the moment of force M of the mass mcp of the working fluid 13 is manifested on the shoulder of the instantaneous radius R relative to the MCV, this moment of force M also causes the force R m of the translational motion of the flywheel 8. As a result, two forces of translational motion act on the bicycle from the flywheel 8:

a) force P d moment of inertia of rotation of the working fluid 13 of the flywheel 8,

T=J· 2 · 1/2, where T is the kinetic energy of rotation of the working fluid 13,

a J=m·r 2, where J is the moment of inertia of the working fluid 13 (kg·m 2), m is the mass of the working fluid 13, r is the radius of the working fluid 13, - angular velocity rotation of the working fluid 13;

b) moment of force M of the mass mcp of the working fluid 13 of the flywheel 8 relative to the MCV,

a M=mcp·R, where M is the moment of force of the mass mcp of the working fluid 13 relative to the MCV; mcp is the mass of the part of the working fluid 13, which is located above its horizontal diameter; R is the instantaneous average radius of the working fluid 13 when the working fluid 13 rotates relative to the MCV.

With a mass m of the working fluid of 5 kg and 2000 revolutions per minute (40,000 rad per sec) of the working fluid 13 and its radius r equal to 0.3 m, the kinetic energy T = 9000 kg m 2 rad sec 2.

When a rigid body rotates around an axis, the role of mass is played by the moment of inertia. During the movement of the bicycle, energy consumption will be about 3 kgm per second, which will ensure the speed of the bicycle at least 50 km/h for 150 seconds without recharging (spinning) the working fluid 13. During this time, about 50% of the maximum reserve of its kinetic energy will be consumed . It will take several seconds to recharge (spin) the flywheel 8 with the working fluid 13 to the calculated speed value. The period of contact of the working fluid 13 of the flywheel 8 with the rim 3 of the wheel 2 is 4-6 seconds at intervals of 8-10 seconds.

AC network as ballast, replacing resistors, but then they are not clamped, but are charged 100 times per second, and the energy stored by the capacitor is used in the external circuit

But if you conjugate an ionisgor - a capacitor with a double electrical layer - into the handle of the frying pan, and place a heating element in the bottom, then such a “miracle* can become a reality

The fact is that the specific charge of purifiers is tens of thousands of times higher than the charge of conventional condenser cells, and they are increasingly used as energy storage devices in a wide variety of devices, even playing the role of spark batteries in cars. So they can easily handle a piece of meat or cutlets.

BICYCLE WITH FLYWHEEL

“I’m a fan of fast cycling, but I don’t want to put a motor on my bike - it spoils the appearance and makes a lot of noise,” writes our regular reader Egor Masalsky from Orsk. - So I came up with a solution: what if you put a flywheel on a bicycle? The flywheel motor is silent and can be easily hidden under a beautiful casing. You can spin the flywheel at home, before going down the alley, and on a trip you can recharge it when going down a hill*.

The idea of ​​a flywheel (inertia) engine is well known. In England, a prototype of the trolle!i6yca was even built, the flywheel of which was spun at stops from the street power supply. E past

In the issue of our magazine, in the special issue “Step into the Future,” we described (the) work of IE student Dmitry Kovalev, who not only came up with the idea of ​​​​an inertial bus for transporting passengers from Surgut to the village of Fedorovsky, but also calculated the parameters that a flywheel engine should have. iBy the way, we suggest that Egor return to his idea and figure out what numerical parameters - mass, size and speed - a bicycle handwheel should have)

Inertial drives have many attractive properties - a large supply of energy, noiseless operation, cleanliness, but there are also disadvantages. The main one that hinders their widespread use in technology is a complex drive from the flywheel to the transfer shaft. After all, the flywheel rotates at a constant, enormous speed, and a rigid clutch, such as a gear clutch, will not work, and clutches are often unproductive and uneconomical, converting a lot of energy into heat. By the way, a bicycle flywheel is easy to connect to a wheel. Just insert a transfer roller between the wheel and the flywheel, as shown in the figure. This mechanism is also far from perfect, but it is pro“-and quite functional, in contrast to the ratchet and sprockets proposed by Egor.

This could make Yegor's idea feasible. But, alas, it’s not just a matter of mechanics. Assessing Egor Masalsky's idea as interesting, PB experts remembered the so-called gyroscopic effect. Any rotating body, and the flywheel is no exception, helps maintain its position in space. And if for a massive car
