All-terrain vehicle with their own hands. Aleksey Garagashyan's Cheburator on suspension All-terrain vehicle differential 4

It was created by the author for simple rides, he has no special purposes, except for entertainment. Although in the future the author does not exclude the possibility of modernization for various whims. In addition, at the moment this machine is able not only to move on land, but also to swim.

Materials involved in the creation of this all-terrain vehicle:
1) Engine from oki
2) gearbox from the Dnieper
3) VAZ classics gave a differential.
4) Onboard brakes and transmissions from the ATV.
5) The wheels are also removed from the ATV 25 12.5 12 .
6) clutch from 2101
7) Brakes from 2108
8) Chains with a pitch of 19.5 German production.

The maximum speed of the all-terrain vehicle is about 40 km per hour.

Consider the progress of the construction of the all-terrain vehicle and the problems that the author encountered.

A drive from 2121 was used, from which the CV joint cup was separated. As a result, a shaft with an end part was obtained, to which the flange of the VAZ hub was welded, and there holes were already made for mounting the wheels. Then all the elements were machined on a lathe. The shafts of the leading stars, as well as the brake discs, are fastened with conventional wheel bolts.

A bearing was made from the semi-axis of the field to connect the splines of the stars and the semi-axis. Part of the bridge of the same Niva is used as a clip. Below is a photo of parts before assembly:

Then the author proceeded to assemble the frame.

First stage:

Made the bottom of the frame:

Installed differential:

Dashboard done:

Then there were the flywheels. They are lightweight. Brake discs are also made from them, by turning to the required thickness. the brake discs are fairly flat due to the vehicle's layout specifications.

Two gearboxes were made, the material was an old bridge from a classic VAZ.

After test drives, it was also decided to lower the gear ratio from the differential by 2.5. After that, the author proceeded to install the gearbox and began the final work on the transmission and wiring.

The main problems of a skid on a differential are the difficulty of turning on the spot and the resource of the differential itself.

It is easier to turn on the gas, as it requires a lot of effort on the spot. Therefore, the author began to solve this problem. The differential was welded and one side was unhooked, thanks to which the car became easier to drive. Even in first gear on the spot, the ATV turns with ease, so it was decided to abandon the side turn due to the differential in favor of more convenient handling.
before that there was four satellite, which was made from a self-block disk.

However, the new rotation scheme also showed shortcomings. In the transmission, case bearings with a cast-iron case were involved, this very case was not designed for overloads and burst during a sharp maneuver.

Therefore, the author decided to replace such cases with steel ones. The author advises to pay special attention to the selection of bearings. In the light of all the alterations that have been made, the transmission scheme has become very complicated: a gearbox is attached to the engine, then it is divided into two clutches from the VAZ 2110 with stars and chains, then there is a gearbox from the VAZ 2101, in which the differentials are welded, and each has brakes of the left and right side. the control itself is implemented due to the working cylinder from the VAZ 2101 with a vacuum booster.

However, despite the apparent complexity of the design, the control itself has become much easier, it is certainly difficult to catch the clutch moment, but on the go it does not cause problems.

The eye engine is installed with its own clutch and gearbox, and only then there is a transition to the Dnieper gearbox, and from bridges 2101, reduction gears by 3.5 were obtained, and then the onboard drive comes from them.

The master cylinders have been replaced on the 2108 to make the clutch work easier.
Of course, quite a lot of effort falls on the Dnieper box, but when driving 30-35 km and the engine speed is under 3000, it holds up quite well.
The chains are imported and durable, they were ordered from Moscow at a price of a thousand per meter.

As for the dimensions of the all-terrain vehicle:
Width 160 cm
Length 280 cm
The mass of the car is up to 600 kilograms, but if you wish, you can throw it off, since no savings work has been carried out in this regard.

Since the body is made airtight, the all-terrain vehicle is able to overcome water obstacles, although the speed is not quite high, since the wheels are too small. In addition, a rather large clearance was made about 45 centimeters to the bottom, so the wheels are quite high on the water and row poorly, but if the clearance is reduced, then there will be problems with moving along the track.

Separately, the reliability of the car pleases, even if one side breaks down, this all-terrain vehicle continues to drive almost straight, which does not cause inconvenience to the driver.

Dismantling the entire transmission to get to the damaged elements is unnecessary, and replacing the clutch, for example, can take as little as half an hour.

For 300 km of operation, only two breakdowns were noticed.

The fan on sensor failed, but in this case, the author prudently installed a forced on switch.

And also while cleaning the snow with a bucket, the drive sprocket was damaged, it simply could not withstand the load of the weight of the snow + bucket during a sharp maneuver.

By the way, here is the same bucket that was made by the author for the all-terrain vehicle:

The author made the following conclusions for himself:
In the future, it is worth seriously considering the possibility of lightening the all-terrain vehicle, as this will greatly reduce the load on the chassis.
Sometimes there are problems with the chains, unfortunately it has not yet been possible to find out the cause.

Some joints were made with an excessive margin of safety, and in particular, it is from them that it is worth starting to lighten the all-terrain vehicle. Although even so, the engine power is enough.

Perhaps a CVT should be installed, but for this you need to take a gearbox from an imported ATV model. Again, in order to save weight, it is worth reconsidering the gearbox layout, since the bridges from the VAZ are quite heavy.

Installing caterpillars will not especially play on cross-country ability, since the all-terrain vehicle is quite nimble.

Video footage of machine testing.

The premiere of a new all-terrain vehicle designed by Alexei Garagashyan will take place at the Vezdekhoder exhibition on October 26 and 27. The name of the all-terrain vehicle is military - "AG-20".

Overall dimensions of the snow and swamp vehicle "AG-20": length 3980 mm, width 2530 mm, height 2580 mm, tires "TROM-16" size 1650x570 with a landing size of 25 inches. Suspension pneumocirculation, works by passing air from one tire to another, all tires are connected by air channels. The declared load capacity is 1000 kg. The volume of fuel tanks is 400 liters of the main tank and 220 liters of additional ones. The power reserve is about 2000 km, the average fuel consumption is 2-3 liters per hour, the engine model is similar to the Sherp all-terrain vehicle. The rotation mechanism is planetary with hydraulic control. Two planetary turning mechanisms are driven by cardan shafts, further from the turning mechanisms, chain drives transmit torque to the wheels. The chains are in an oil bath, the tension of the chains is carried out from the passenger compartment.

The Sherp all-terrain vehicle is already a passed stage, and there is no doubt that the "AG-20" has surpassed the previous all-terrain vehicle in many ways, especially considering the thorough preparation of all the all-terrain vehicles created by Alexey for multi-day trips. We will compare "AG-20" and Sherp in detail and describe its unique technical solutions.

When comparing the dimensions of the new AG-20 all-terrain vehicle with the Sherp all-terrain vehicle, there are very big differences, the Sherp seems like a midget, getting into the AG-20 cabin is no longer as easy as in the Sherp. Although it seemed difficult to climb into the Sherpa, everything is known in comparison. The mass of the new all-terrain vehicle is almost the same as that of the Sherpa, the difference in mass, depending on the configuration, can be 50-100 kg, but at the same time, the all-terrain vehicle is much more spacious and warmer inside. All windows, except for the windshield, are double-glazed, the all-terrain vehicle is covered with aluminum, insulated. On the front of the frame of the all-terrain vehicle there are places for quick installation of special technological equipment, a blade, a bucket, etc. Accordingly, the design includes the installation of hydraulic equipment for driving mounted units.

The driver's and front passenger's seat is very spacious, you can stretch your legs, as in a passenger executive Lexus. The interior width is also impressive, despite the fact that larger tires are used and the all-terrain vehicle remains at a width of no more than 2550 mm for free transportation on public roads.

The all-terrain vehicle is side-turning, it is controlled by a steering wheel by means of a hydraulic drive. A tablet computer based on the Windows operating system is installed between the handles of the steering wheel.

15" touch screen navigation tablet rotates with steering wheel.

Pressure gauges in all-terrain vehicle systems

All the main control buttons of the all-terrain vehicle are located on the steering wheel, almost everything is controlled by buttons and remotely, there are at least mechanical levers. Wheel inflation is controlled by buttons, on the first Sherpas everything is done manually, mechanically.

If we compare the interior of Sherpa and AG-20, then Sherp is a one-room apartment, and "AG-20" is a two-room apartment;

There are several boxes for "gloves" in the all-terrain vehicle:

The all-terrain vehicle has two fuel tanks with a total capacity of 400 liters, plus canisters can be installed in the rims, for a total fuel supply of more than 600 liters. Presumably, the average fuel consumption will be 35 liters / 100 km, so the range is about 1700 km. The fuel tank openings are located in front and behind the all-terrain vehicle.

The bottom of the all-terrain vehicle "AG-20"

Duralumin beadlocks, on the first Sherpas, were steel, heavy and very durable.

The tire pumping pipe for the AG-20 all-terrain vehicle, the diameter of the pipe is impressive, visually it seems that the section is larger than that of the Sherpa, which means that the pneumocirculation suspension will work better and the tire pressure can be adjusted faster.

Double glazing with polycarbonate.

All lighting equipment of the all-terrain vehicle is LED, there are 6 headlights, each of which has a power of 90 watts

An interesting documentary: "Where there are no roads | The story of the inventor Alexei Garagashyan"

Fri, 10/25/2019 - 12:10

The car stopped right at the edge of a snow-covered cliff. Below, under the high bank, a river flows. Muscles tensed involuntarily, and a crazy thought visited his head: “Does he really want to dive off a cliff?” No, we seem to be driving off, and there will be no death trick. Backing slightly, the car approaches the shore again. The view from above is exactly the same - dizzying. Pause. Then the driver gives gas, and we still break down ...

Side-turning snow and swamp vehicle ("cheburator") Universal highly maneuverable all-terrain vehicle for travel and expeditions. It can also be used to monitor power lines in hard-to-reach areas and clear debris from ice in rivers and lakes.

Oleg Makarov

However, nothing of the kind that the imagination painted happened. The descent was soft, smooth, we did not roll over and did not break our necks. The car is unusual. And with an unusual name - "cheburator". And behind the wheel, that is, no, behind the levers of the "cheburator" Alexei Garagashyan is a real guru among enthusiasts of snow and swamp construction in St. Petersburg and other parts of our large country.

What is a "cheburator" can be understood only by riding this all-terrain vehicle. On the surface, nothing special: a simple box body with a simple design, a small cab with Spartan comfort and very, very large wheels. We are driving through a snow-covered field, somewhere not far from the St. Petersburg Ring Road. The car weighing a ton rolls softly and smoothly, leaving a barely noticeable shallow mark on the snow. But as soon as we decided to dismount, we fell into the snow almost to the waist. This is really an all-terrain vehicle!

Designer - Alexey Garagashyan. Universal highly maneuverable all-terrain vehicle for travel and expeditions. It can also be used to monitor power lines in hard-to-reach areas and clear debris from ice in rivers and lakes. Alexey Garagashyan's passion for wheeled vehicles began in childhood - with the independent design of bicycles. Then came the passion for motorcycle tourism, and, finally, Alexei took up the design of all-terrain vehicles on low-pressure tires. He spends more than 100 days a year traveling on an all-terrain vehicle, traveling and laying tracks for the Championship and Cup of Russia in trophy-raid.

What to get on the ice?

To get acquainted with the snow and swamp vehicles from St. Petersburg, we came to the Northern capital twice - both times in the spring, which came after the memorable snowy winter. They wanted to catch the most "all-terrain" nature with mud, deep snow, thin, crumbling ice. Now, when this nature is approaching us again with autumn, it's time to tell you how cars look and what they are made of, which do not care where to go. Well, almost anyway.

“The main feature of such machines is the wheels,” explains Alexei Garagashyan. - The all-terrain vehicle primarily consists of wheels, and then we can talk about the engine, transmission and chassis. The larger the wheel, the greater the cross-country ability of the all-terrain vehicle, the better it swims. With large tires, he acquires properties that are not available to other vehicles. For example, it can get out of the water onto the ice. I don't know of tracked vehicles that can do this."

The machine is equipped with a 1.5-liter Japanese Kubota turbodiesel. The motor has a low weight (114 kg), a power of about 44 hp. torque 120 Nm. A separate important detail is the absence of an electronic control unit, which increases the reliability of the engine when operating in an environment of water. The car has two beds, a trunk of 600 liters. Fuel consumption in the campaign - 30 liters. per 100 km.

The trick with getting out of the water to the ice edge (however, quite practical) is one of the most impressive features of the “cheburator”, which is not least evidenced by the number of views on YouTube of the corresponding video. In this video, Garagashyan either falls into a hole on his all-terrain vehicle, then, having swum for some distance in open water, he again climbs onto the ice and rolls as if nothing had happened.

Of course, to do this, the machine must have a number of design features. The first of them is the ratio of the volume of wheels and the mass of the car. If an all-terrain vehicle that finds itself in the water stays afloat, plunging somewhere to the axle line, then it has a chance to get out onto the ice. To jump onto the ice, you need a certain acceleration. But where to get it if the all-terrain vehicle does not have a propeller? The rowing machine will be wheels, for which it needs a sufficiently embossed tread. Such a protector is also needed in order to cling to the edge of the ice. And one more important point: in order for the wheel not to slip, the pressure in it must be very low, for example, 0.02 atm. If the pressure is high, and the wheel is hard, unbreakable, then driving an all-terrain vehicle onto ice will be as difficult as climbing onto the sidewalk curb with an asphalt roller.

In general, low-pressure wheels are a prerequisite for super-passability. True, such wheels have one problem: when deformed, they are easily disassembled. You can, of course, use beadlocks - special locking devices that are used, for example, on jeep trial cars. But the "cheburator" has its own zest.

Big ears "cheburator"

“Instead of beadlocks, Garagashyan’s machines are embodied in the know-how created by the designer — wheels of a special design,” says Vyacheslav Ermakov, another St. Petersburg enthusiast, head of the lunohodov.net website dedicated to snow and swamp construction. These discs are very light, dirt falls off them, and ice does not freeze on them, sometimes forming lumps weighing up to 100 kg on the wheels of all-terrain vehicles. But the main feature is that the disc body is rolled onto the bead ring. The protector is rigidly attached to the disc and does not rotate, which eliminates disassembly. And there is nothing low-tech in this - after all, in any case, a large wheel is placed on the disk for almost its entire service life, unless it suffers fatal damage as a result of an explosion or a collision with a metal pin.

The quality and properties of tires also affect the properties of the all-terrain vehicle. Tires for snow and swamp vehicles are produced in Russia, but Aleksey Garagashyan does not consider their quality to be optimal. Rubber needs to be refined: individual tread elements are cut off from it, which makes the wheel lighter, improves its self-cleaning and makes it less brittle. In addition, additional grooves are cut out on the surface of the wheel. "Cheburator" climbs steep slopes, and then again rushes down, dashingly rolls over the crust, successfully fights with loose snow, and on the still strong ice of a small pond, arranges a real drift dance. As mentioned above, there is no steering wheel in the all-terrain vehicle: it is controlled like a tank - by braking one of the sides.

peaceful tank

“I use the onboard drive according to the simplest scheme,” says Alexei Garagashyan, “with a large KAMAZ differential between the sides. Shafts come out of the differential, on which ventilated brake discs with a diameter of 315 mm are installed. From the shafts - chain transmission to the wheel hubs. The control is carried out using the gas and clutch pedals, as well as two brake levers. The advantage of this design is high maneuverability (all-terrain vehicles with steering have a very large turning radius), relatively low weight, and overall simplicity of design.

The disadvantage is that when driving, you need to slow down one side. In this case, the energy of the engine is wasted, the brakes are heated. Accordingly, you need a very high-torque engine, and even with a good diesel, you have to shift to a gear or two lower in order to turn sharply enough. One of the most interesting features of this side-turning “cheburator” is the lack of suspension. Or, more correctly, a mechanical suspension. Instead, a pneumocirculation suspension was used (this is the designer's own term). Its essence is that all four wheels are connected by a large-section air line - 45 mm. Therefore, when hitting an obstacle, the air flows very quickly inside the system and the pressure in all wheels equalizes.

When hitting a large stone or stump, the wheel is deformed almost to the disk, but the machine does not lose contact with the ground. But if the excess pressure from the compressed wheel had nowhere to “bleed”, the car would simply hang out. The suspension, which essentially consists of wheels and an air line, provides a soft, jerk-free ride, but ... at low speeds. With faster driving, the absence of shock absorbers, of course, affects. By the way, the wide air line also serves to quickly inflate or deflate tires - these processes can be controlled from the cab. Pumping is carried out using the exhaust of a diesel engine, which, contrary to popular belief, does not corrode rubber at all.

Designer - Denis Globin. The funny name "mymyklovoz" comes from the Internet nickname of Denis Globin. A car can safely run over a person, and he will remain safe and sound: thanks to low tire pressure, the weight of the all-terrain vehicle is distributed over the huge contact patches of the wheels.

Sukhaty and six hunters

When spring took its toll and water splashed near the shores of recently tightly ice-bound reservoirs, we again came to St. Petersburg to get acquainted with another machine created by St. Petersburg enthusiasts and test it in action. The snow and swamp-going “myklovoz” boldly rushed into the water of the lake, most of which was still covered with a translucent crust. In order to understand how cool this car is, it would be enough for us just to drive to the place of our tests.

The engine is from Daewoo Matiz, but any small engine can be used. The transfer box from the "Niva", two bridges from the UAZ car. Tires "Trekol" are protected from disassembly by beadlocks. Steering gear from Tiyota Land Cruiser. The technical solutions used in such all-terrain vehicles sometimes contradict the classical principles of automotive engineering. Can tractor wheels be adjacent to a transmission brake from a moped? In the "mymyklovoz" - yes.

All-terrain vehicle weighing a ton with an engine with a capacity of about 50 hp. jokingly drove along a rollicking forest path at once six people. In the cab, in the rear luggage compartment and in the roof rack. Experienced hunters said that when hunting (and hunting in the distant wilds is one of the main purposes of the "mymyklovoz"), voluminous equipment is added to the crew of the same size, and if you're lucky, the carcass of an elk.

The owner and author of the “mymyklovoz” is Denis Globin, and his creation is somewhat different from the airborne “cheburator” of Alexei Garagashyan. “That car is a professional, super-maneuverable all-terrain vehicle,” explains Vyacheslav Ermakov. - A "mymyklovoz" - a car for outdoor activities. She has conventional steering, is also capable of off-road capability, can swim, climb steep banks, has a higher cruising speed and is more aesthetically pleasing.”

While we are looking at how the "myklovoz" cheerfully beats up the lead, the color of the sky, the water of the lake with its protectors, storming the already thinned ice edge, I remember that these cars were not created at all for demonstration performances. They are built for long trips through forests and swamps, for example, on the Kola Peninsula. The cars purr over the swamps and then stop. To communicate with each other, chart the way forward or organize a tea party, the crews get out of the cabs and stand on huge wheels. In no case should you go down - you can get pretty wet, or even die in the swamp. But the machine will withstand everything, it can be completely trusted.

A distinctive feature of this all-terrain vehicle of the Cheburator type is an independent suspension. On the all-terrain vehicle, a pumping system with fast exhausts was implemented. A special place in the all-terrain vehicle is given to comfort, this applies to both the suspension, steering, and the actual placement of goods and passengers in the car.

Materials and parts used to create this all-terrain vehicle:
1) diesel turbocharged Kubota engine with a capacity of 44 hp with a volume of 1500 cubic cm.
2) Radiator VAZ 2108
3) 40 A generator
4) battery 75A per hour
5) gearbox from VAZ 2108
6) Brakes and caliper from VAZ 2108
7) Gazelle gearbox
8) Dosing pump 100 cm cube
9) Power steering pump ZF
10) Power cylinder from GAZ 66
11) Fuel tank 63 liters
12) Electric winch.
13) LED headlight 120 watts
14) Tires 1300 x 700 x 21 Arktiktrans
15) cardan joints from Kamaz

Let us consider in more detail the main elements of the schemes of all-terrain vehicle mechanisms.

The all-terrain vehicle has the following dimensions: width 240 centimeters, base width 210 centimeters, weight under a ton.
the machine is capable of carrying loads up to 400 kilograms. the all-terrain vehicle also has a trunk with a volume of 400 liters.
The width of the disk is 55 centimeters, the weight is 15 kilograms.

The engine of the cube has a torque of 120 Nm, as well as a fuel consumption of about 2 liters per hour.

This is what the engine bay looks like:

The holes are designed to switch the winch lock, as well as laying the cable correctly.

Steering mechanism:

Dosing pump installed:

Driver's seat:

The steering is made according to the hydrostatic scheme, without mechanical connection.
Thanks to this control scheme, at low speeds, there is almost no effort on the steering wheel, but when you try to quickly turn the steering wheel, there is noticeable resistance.

Instead of a differential for the bridge, a special one-piece assembly part was made, which is sharpened for native bearings and to which the driven gear will be screwed, and oversized axle shafts are inserted into the ends.

The all-terrain vehicle is equipped with a quick pumping system, which increases the overall cross-country ability of the vehicle.
Thanks to the use of the suspension, it becomes possible to develop greater speed while remaining in comfort.

Thanks to the width of the all-terrain vehicle at 2 meters 40 centimeters on the wheels, the all-terrain vehicle has excellent stability on the water. When overcoming rivers and lakes, the all-terrain vehicle plunges along the axis. Also, thanks to the large size of the wheels, the all-terrain vehicle travels quite easily through the swamps.

The author paid special attention to easy accessibility to any mechanisms (generator, power steering pump, dosing pump) of the all-terrain vehicle in case of repair. even the gearbox and clutch can be changed directly from the car. It is possible to get the engine oil dipstick, but it is more convenient to do this not from the passenger compartment. But in order to change the air filter to leave the car is not necessary. the fuel sump is clearly visible from the outside and is serviced without special tools, and changing the fuel and oil fine filters does not even require removing the hood.

To clean the radiator, it is enough to unscrew only two M6 bolts and remove the protective shield.
It’s impossible to remove a diesel engine without special tools, but this is unlikely to be required, because diesel engines have excellent reliability.

Kubota diesel engines are made only in Japan, which is an additional guarantee of engine quality and reliability. This in-line injection pump is considered one of the most reliable in the line and has long been loved by most all-terrain vehicle builders. There are three filters that protect against water and dirt.

Even if you fill in low-quality diesel fuel with dirt impurities, then only the first of the three filters will clog, after cleaning or replacing which it will be possible to start the engine again. There will be no consequences for the engine itself.

Wheels with arctictrans tires installed:

A 120-watt headlight is installed, which turns into a combat position at night, and returns back during the day so as not to reduce the driver's view, which is quite convenient.

Below you can see the exit, as well as fixing the winch cable:

Here is the left steering knuckle, top view:

And this is how it looks from below:

From what is not visible behind the skin of the car, I would like to note the presence of the power part of the frame. The gearbox, winch, power relay from the winch are also hidden. The all-terrain vehicle has a hydraulic handbrake and a transmission brake in a single copy.

The all-terrain vehicle does not have a silencer as such, the exhaust pipe is simply insulated with thermal insulation.
Also, a short cardan shaft is installed on the all-terrain vehicle, which is hidden behind the skin of the all-terrain vehicle and a hose for pumping the rear wheels.

In the front panel you can see the air filter hatch:

Since there is no way to weld the rods to the bridge due to the strong possibility of deformation with such an attachment, the author decided to use silent blocks:

Wheeled all-terrain vehicle on low pressure tires do-it-yourself: photo of the building with a description of the all-terrain vehicle.

Craftsman Andrey from Vologda, assembled a home-made all-terrain vehicle for off-road trips, we suggest that you familiarize yourself with the design of the vehicle in more detail.

Building materials:

Wheels Trekol 1310 x 490 x 20.
Engine and gearbox from VAZ 2108.
Cardan drives for bridges, as well as bridges from UAZ.
Steering from UAZ.
The brakes are hydraulic with a vacuum booster.
Suspension rear springs lightweight UAZ.
Steering worm gear UAZ.
Other spare parts from VAZ.

The frame of the all-terrain vehicle was welded from profile pipes.

We made wheels for wheels for low pressure tires.

The bipod was lengthened to reduce the effort when turning the steering wheel.

The author of the all-terrain vehicle provided for the installation of various wheels in the all-terrain vehicle, for this it is enough to change the gear ratio from the gearbox. Thus, when installing Trekol wheels, the main pair in the gearbox changes from 3.8 to 5.1, the maximum speed is cut, but the minimum speed is 1 km / h.

The differential was welded, because if not welded, the patency will be poor. Sometimes this is solved by installing self-locks, but it only works at a time at high engine speeds, at low speeds its usefulness is doubtful.

There is a preload clutch, it connects the axle shafts with a certain force and when the force is exceeded, the axle shafts rotate relative to each other, and the mechanism works like a conventional screw lock, that is, it eliminates the occurrence of peak loads in the vehicle's transmission and on the steering wheel, as well as allows self-locking to operate earlier at low speeds.

And in a situation where the moment is absent on one rotating wheel, it makes it possible to reliably connect the second wheel of the same axle to work, that is, for example, when one wheel is in the air due to terrain conditions and is not under load. Basically, such specialized self-blocks are installed only on the rear axle of the all-terrain vehicle.

The turning radius on the outer track of the wheels is 6 meters.

Gear shifting was implemented in a similar way.

Overall dimensions of the all-terrain vehicle:

Length - 255 cm.
Width - 203 cm.
Height - 227 cm.
Length from an all-terrain vehicle with a trailer - 595 cm.
Ground clearance - 50 cm.

The mass of the all-terrain vehicle is 1050 kg.
Load capacity on land 500 kg.
Carrying capacity on water 300 kg.
The number of passengers is 5 people.

Fuel consumption is from 15 to 30 liters per hundred kilometers, depending on conditions and road surface.

Homemade all-terrain vehicle develops a maximum speed of 60 km / h. Minimum speed 3 km/h. When driving on water, the speed of the all-terrain vehicle is 4 km / h.
