Good afternoon friends! We continue to talk about the various intricacies of the car device. We have already considered the varieties. It's time to pay more attention to suspension and chassis issues. Do you know what a torsion bar suspension is? If not, then it's time to talk about this in more detail.

Today, there are various options for car suspensions, each of which has its own operating principle. But we will pay attention to the type indicated above. At their core, these are torsion shafts that are designed to work in torsion. One end of the shaft is secured to the chassis, while the other is secured to a lever perpendicular to it. For the manufacture of parts, high-strength steel is used, which is capable of withstanding very heavy loads during the torsion process.

In contrast to the spring structure, where the main working element is the spring, here this role is played by the torsion bar. This is an elastic shaft, which is rigidly fixed to the supporting frame, and at the other end it is connected to the wheel hub. If the suspension is front, then in such cases the torsion bars are attached to the transverse lower arm.

The main elements of the torsion bar suspension are the following parts and mechanisms:

• upper and lower wishbones;
• wheel hub;
• stabilizer lateral stability;
• shock absorber;
• longitudinal torsion bar;
• stretcher.

Mounting options

The location of the torsion beams can be transverse and longitudinal. On passenger cars especially those with rear wheel drive, they are usually located transversely. The principle of operation of the torsion bar suspension is aimed at making the ride smoother, regulating the roll of the car during maneuvers, and reducing oscillations of the steered wheels. In some Vehicle ah, this suspension option is used for automatic leveling to give the beams additional rigidity, which is sometimes needed when driving on poor-quality road surfaces.

The most common version of this type of suspension is a semi-dependent rear suspension in vehicles with front wheel drive. In this case, it is a pair trailing arms, which are interconnected by a U-shaped beam. Thanks to this device, the beam has the ability to work for twisting, as a result of which the wheels overcome road irregularities independently of each other.

Advantages and disadvantages

So, the main advantages of this design are as follows:

• easy height adjustment if necessary;
• relatively low weight and dimensions;
• durability and reliability;
• compact design in relation to the width of the car, compared to some other types of suspensions;
• ease of maintenance and operational simplicity.

In addition, the suspension of the torsion sample has the ability to adjust its rigidity, which will not work in the case of a spring structure. This adjustment can be made not only in manual mode, but also with the help of specially designed electric motors.

Of the disadvantages inherent in such a suspension, one can note the excessive maneuverability that the car acquires. Such disadvantages can be especially noticeable in the case of small cars. Instead of the usual turn, they can easily turn around if the driver loses his guard. Today, torsion bars are not used as often as before. They were gradually replaced by multi-link designs. But torsion bars are often equipped with trucks, trailers and classic SUVs, designed not only for movement in urban mode.

A little history in the end

For the first time designs of this type began to be used on Volkswagen Beetle cars from the 30s of the last century... During the war and post-war times, they were repeatedly refined, modernized, used in truck structure. Today, torsion beams can be found in some Toyota models (in particular, SUVs are equipped with it), sports cars Ferrari. The French auto industry has developed its own varieties of such systems. So, the Citroen concern found a connection between the beam length and the degree of suspension comfort, which found expression in this manufacturer's own designs.

The system worked so reliably that it was used more than once for military equipment... As for the Soviet auto industry, ZIL trucks, as well as passenger cars Zaporozhets and LUAZs, were equipped with torsion bars. Until the early 1960s, they were installed exclusively on the rear suspension, but it was Jaguar who first used front torsion bars.

When choosing a car, every car enthusiast spends a long time in deep thought, sometimes tormented by his experiences and fears, and sometimes lives in anticipation of this joyful moment - - for someone first, and for someone the next. However, there are many issues to be resolved, and one of them is the car with which suspension to choose.

It's better to decide in advance what kind of suspension you want.

Suspension - what is it?

Surely not every one of us in the 21st century had the opportunity to ride in a horse-drawn cart on a cart, to experience the sensations of every dimple and pothole. So this is the clearest example of a vehicle without the same suspension. It is such an important part of the car as the suspension that determines the level of comfort, ease of control, as well as stability and cross-country ability. Today there are several types of pendants, among which the following main parts can be distinguished:

• Fasteners.
• Stabilizing elements of lateral elasticity.
• Distributing elements of the direction of force.
• An extinguishing moment.
• Elastic elements.

Each type of suspension has its own pros and cons.

Suspension by degree of elasticity

According to the type of elastic element, the suspension is usually divided into four types:

• Torsion bar.
• Spring loaded.
• Leaf springs.
• Pneumatic.

Torsion bar suspension represents rods twisting under load. One of the torsion bars is high elasticity. The basis of the structure is made of steel, hardened under the influence of high temperatures... If the torsion bar suspension is briefly characterized, in just a few words, then the following immediately comes to mind: resistance to shock loads, durability, compactness.

The leaf spring suspension has found its application for a long time. Even wealthy nobles could afford to equip carts with a spring suspension, which significantly increased the comfort of travel. The base is metal plates connected together, which partially act as shock absorbers, reducing the load on the latter. Advantage - high endurance, disadvantage - not the best, to put it mildly, elasticity indicators and a large mass of the structure.

The air suspension is characterized primarily by high cost and increased level comfort. In vehicles with air suspension ground clearance can be adjusted in height, and the degree of elasticity can also be adjusted. Due to its complexity, this type of chassis is not widely used in our country.

The spring undercarriage, which is the main "competitor" of the torsion bar, has a very wide application... The main advantages are low cost, availability, reliability, as well as providing more comfort. Cons - low load capacity, spring sensitivity to high loads.

Torsion bar or spring?

So which suspension is better: torsion bar or spring? Owners, experts and ordinary people cannot find common ground, challenging each of the opinions on the question of which, in the end, undercarriage select. Modern manufacturers began to combine in some car models and use both types of elastic elements. For example, the so-called "heels" or "pickups" have a front spring suspension, and the rear - a torsion bar, which provides excellent softness and comfort for passengers and the driver, and it is possible to carry small loads weighing a couple of hundred kilograms. Fully spring-loaded suspension can be used in cars executive class, in those vehicles that do not imply the transportation of even medium-sized cargo.

Dependent or independent ?!

Every motorist should also think about this question when choosing his "swallow". It is on the suspension is divided: dependent and independent. Dependent is a structure in which two wheels of one axle are rigidly connected to each other. In this case, the movement of one wheel in the axle affects the movement of the second. The dependent "design" is used mainly on rear-wheel drive cars, a shining example are "Zhiguli", as well as powerful heavy-duty cars and tractors. One of the main disadvantages of this type is the heavy assembly weight. In the case when the bridge is used as a leading one, the smoothness of the ride is lost.

Independent suspension is a complex design in which one wheel in an axle does not depend on another wheel in the same axle, and if there is some dependence, then it is minimal. Now manufacturers use several types of this type of construction: McPherson (McPherson), multi-link, single-link. Each of them, naturally, has its own advantages and disadvantages. The most effective, soft and comfortable is multi-link, but it is also the most impractical and expensive to operate. It is widely used in executive cars. Most of the vehicles in use use the MacPherson strut - semi-independent suspension with average cost service and an acceptable level of comfort.

Operation in Russia

Determine which is the best suspension for Russian roads, our compatriots cannot specifically. It all depends on the purpose for which you take, what you expect from it, from what price range it is. Your driving style also greatly influences the choice. Best suspension the car is one with which you will feel confident on the road and comfortable in the cabin. For the transportation and delivery of goods, it is better to use a more durable suspension, that is, a torsion bar or even a spring one. For daily driving in the city in a small car or an economy class car, you can choose a MacPherson strut or single-link suspension. Business class, of course, got used to comfort, for them a multi-link independent suspension will be an excellent basis for a comfortable ride.

Make a choice only in the right direction, and, as they say, no nail, no rod!

Torsion beam refers to a type of suspension that uses a torsion bar as an elastic element. This metal bar is characterized by a circular cross-section, at the ends of which there is a splined connection. The torsion bar itself includes:

• set of plates;
• rods;
• beams of the established section.

The torsion bar structure is attached from one end to the frame or car body, and from the other to the lever. The rotation of the wheels contributes to the twisting of the torsion bar, due to this, an elastic bond is achieved between the body and the wheel. The peculiarity of the mechanism: it rotates only in one direction - in the direction of twisting. Another feature is that the torsion bar is used to adjust the height of the body. This type of suspension is used among independent suspensions:

• double wishbone;
• trailing arm;
• associated trailing arm.

Schematic torsion bar suspension arrangement

Double wishbone torsion bar suspensions are located along the body. This factor provides that their length, respectively, and elastic properties are adjustable in a wide range. As mentioned earlier, the torsion bar structure is attached from one end to the body or frame of the car, and from the other to the lever. Some models of Japanese and American SUVs uses this mechanism as the front suspension of light vehicles with off-road vehicles.

In a torsion-type suspension, the trailing arms of the torsion bars are connected longitudinally, respectively, located across the body. This design looks like a rear suspension on some models light vehicles small class.

Schematic structure of a torsion beam

A special place in the construction of this type of suspension is given to the torsion beam. As a guiding device, two trailing arms are used here, fastened together by a beam. The trailing arms are fastened to the body on one side and to the wheel hubs on the other. The beam is characterized by a U-shaped cross-section. This factor gives the unit a greater degree of flexural rigidity and less torsional rigidity. And thanks to this property, the wheels are able to move up and down from each other independently.

An approximate schematic composition includes:

1. rubber-metal hinge;
2. shock absorber;
3. cross beam (torsion bar);
4. coil spring;
5. wheel hub;
6. trailing arm

Longitudinal or transverse placement

The placement of the torsion bar parallel to the longitudinal axis of the vehicle is characteristic of the front wheels of certain types of SUVs and commercial models. Rear torsion bar suspensions are characterized exclusively by passenger cars designed for a small or lower segment of the middle class. In this case, they are characterized by a transverse arrangement relative to the body.

The peculiarities of each type of torsion suspension are reflected when it is necessary to resolve issues related to their maintenance in a technically sound condition. Let's take a rear-type torsion beams as an example. And let's start looking for an answer to the question regarding the restoration of car beams with our own hands.

Causes of malfunctions

• The most weak point beams are bearings. The service life of any type of bearing is governed by its wear. Needle-type bearings are no exception, because no one has canceled the factors that accelerate depreciation. This part of the beam system is not subject to shock loads. Therefore, the impact of jolts from high-speed driving, in contrast to hub bearings, is unusual for them. In most cases, they suffer from entrained dirt. Any sealant cannot be avoided from aging, and water will immediately flow through the smallest hole. As soon as moisture gets inside, you can say goodbye to the bearing. Extraneous sounds emanating from the beam on an uneven surface are signs of bearing failure. If you start repairing immediately, the car owner will get off with a simple replacement of worn parts. Neglecting this factor leads to a complete replacement of the shafts. It was not in vain that they were developed standard terms replacement of bearings every 60 thousand km, even though no signs are observed. When the wheels of the vehicle fit into the shape of a house, it will hardly be possible to get out of the situation solely by replacing the bearings.
• Shock absorbers and springs. These problems are not very common in practice.
• Torsion bar as a source of malfunctions. Depending on the model, there may be two, three or four of them. The reason for the wear of each option is damage to the splines, with the help of which the torsion bars are connected to the pipe and levers, or the break of the rod. The fatigue strength of the torsion bars is high, but not unlimited. The torsion bars settle in the same way as the springs settle, thus reducing the clearance of the rear of the car. The features of the torsion bar suspension allow, by reinstalling the torsion bars, not only to return the original position of the body, but also to increase the ground clearance, if necessary. However, fatigue stress gradually builds up in the rod, and corrosion reduces the torsion section, which ultimately leads to breakage. There is nothing more to break in the torsion beams.

Self-replacement problems

If it is necessary to dismantle the beam, it is unrealistic to cope with this work on its own. The part is characterized by significant weight and dimensions. Pressing out old shafts and further installation in their original place requires heating and associated hot work. Shafts cannot be dismantled otherwise without the help of a special press. It requires quality preparation seats... And without solid experience, it is extremely difficult to correctly set the torsion bars and ground clearance.

Role of additional elements

Shock struts in a torsion-type system are very important. Thanks to their device, vibrations of the body, suspension elements and attachments... Shock absorber in modern production presented in two types: one-pipe and two-pipe. The characteristics of each type of shock absorber depend on their design. Automotive shock absorbers depending on working fluid are divided into gas, oil and gas-oil. The shock absorber strut support is a device with which the shock absorber itself is attached to the upper part of the car body.

Modern analogues

The torsion beam has now become popular as a rear suspension in front-wheel drive cars belonging to the small and middle class. Due to the design, the suspension and shock absorber with a torsion beam occupy an intermediate position between the dependent and independent type of suspension, it is this factor that determines its second name - semi-independent suspension.

Tanks are the most famous carriers of torsion suspensions among vehicles.

The rear beams and shock absorber of French cars sometimes characterize that - tank - meaning their reliability. They are really reliable, however, they can be reproached with the difficulties of repair and its high cost in comparison with beams, where elastic elements are springs.

Not really

The article describes the principle of operation and the device of a torsion bar suspension of a car. The main pros and cons are introduced, as well as the device, diagram and prices of parts. At the end of the article, see a video review of torsion bar suspension repair.

The content of the article:

Torsion bar - refers to the class of independent suspensions, which is based on a torsion bar. He is like the main one elastic element, which is applied flush with the air bellows or spring. This type of suspension provides the car whole line pluses: smooth running, compactness, simplicity of design. But there are also significant disadvantages, such a design has the worst controllability and rolls of the machine itself. As a result, given view not often found on modern cars.

The history of the appearance of the torsion bar suspension

The first mention of the appearance of the torsion bar suspension dates back to the 1930s of the last century. Then it was installed on French Citroen cars. Since the 1940s, the mechanism migrated to racing cars from Porsche. In the future, the design began to be used on ZiL, Chrysler and Renault 16 cars.

Then the main plus was in the smoothness of the ride, simplicity of design, and of course inexpensive parts in case of repair or production. Progress was not long in coming, and over time, due to poor handling, the entire mechanism faded into the background, giving way to the suspension. Nevertheless, at Chrysler, this suspension lived the longest, due to its simple design, it was installed on cars from 1957 to 1989 inclusive. The very word torsion is translated as twisting, respectively, this is the basis of the work of the part.

What are the torsion bar suspensions of the car

Despite the fact that the torsion bar suspension showed itself only 50% with better side, she found many applications on different cars... Accordingly, there are several types of refinement of the mechanism. As a rule, there are three main variations:

• front torsion bar on wishbones;
• rear suspension with transverse torsion bars;
• semi-independent rear torsion bar suspension (beam).

Each of the listed types differs not only in structure, but also in characteristics and design. The front torsion bar suspension includes:

• longitudinal torsion bar working on the twisting principle;
• lower and upper arm;
• shock absorber;
• anti-roll bar.

Such a set of parts makes the whole mechanism compact, which makes it possible to modify the wheel drives, install tires of a larger diameter. It was these moments that served as a plus for the production frame SUVs, which should combine softness, smoothness and increased cross-country ability... As an example, such a suspension can be found on Toyota SUVs Land cruiser 100 or Toyota Hilux Surf.

The second type is the rear suspension with transverse torsion bars. In such a mechanism, the main torsion bars are located transversely. This is exactly how the system was arranged in the legendary French car Renault 16, produced in the 90s of the twentieth century. At the front, the car received a suspension with a longitudinal arrangement of torsion bars, but at the rear - with a transverse arrangement. The popularity of the model was due to free space in the cabin, in particular luggage compartment... The use of this design significantly freed up space in the trunk, but there were also disadvantages.

Was very interesting design feature of such cars... To the extent that one torsion bar is located behind the other, this led to a difference in the wheelbase of the car. One wheel on one side was closer to the front by a few centimeters, the other wheel, on the contrary, was a few centimeters farther. It was difficult to see by eye, since there was practically no comparison from the side, but the car's handling was not the best, in the same way as stability on the track (especially on high speed). Today, such a suspension scheme is not used by auto manufacturers, to the extent of safety reasons.

The last option is a rear semi-independent torsion bar suspension. As a rule, it is of the correct U-shape, which has received an elastic rod inside. Due to this design, the wheels of one axle can move slightly from each other, which makes it possible to drive bumps more smoothly. Thus, it is achieved better stability and vehicle handling. As a rule, the suspension is used on rear axle most of budget cars front-wheel drive. Inexpensive production, relatively cheap parts and good performance.

What is a torsion and how it works

Often, the principle of the structure of one of the above-mentioned types of suspension is different, respectively, and the details will differ from each other.

According to the device, a torsion bar is a metal rod or shaft, the main task of which is to work on twisting (only in one direction). If we consider it in a dissected form, then in shape it can be square or round, much less often in the form of plates, which consist of several layers.

For the system to work, one part of the torsion bar is rigidly attached to the suspension (carrier arm), due to spline connection... The second part is fixed on the car frame or body, depending on the design. Engineers calculate in advance the torsional resistance force of the torsion bar, thereby optimally designing it to support the weight of the car and a stable connection between the frame and the car body.

This is the same principle used by engineers when designing anti-roll bars. The main characteristics to consider are thickness and length. It is they who play a role in the softness of the suspension and are able to withstand the necessary overloads; if these data are violated, breakage or bending may occur. To protect against rye and other damage, from the moment of production, the parts are covered with a special rubberized material, as well as an anti-corrosion agent.

The principle of operation of a torsion bar suspension reminds many of the operation of a leaf spring, air or spring suspension. Above the described parts, it is clear that the torsion bar, the main part, acts as a spring. At the moment of operation, the force is transmitted to the torsion bar from the main, bearing lever.

Thus, the rod is twisted to the required or possible limit. At the moment when the load decreases, the bar returns to starting position... This aligns the position of the support arm.

The video shows the principle of torsion twisting

Pros and cons of torsion bar suspension

As with any mechanism, the torsion bar suspension can surprise with both positive and negative aspects. To do this, consider them in the table:

Pros and cons of torsion bar suspension
pros	Minuses
Compact dimensions	Poor vehicle handling
Light weight of parts	Difficulty in the production of the torsion bars themselves
Smooth running	It is almost impossible to achieve good sound insulation
Good maintainability	You need to drive carefully and carefully.
Reliable and simple suspension design	The torsion bar has a tendency to pop
Inexpensive service	-
Self-adjustment of suspension stiffness (sometimes clearance)	-

To fully appreciate the pros and cons of the torsion bar suspension, you can only travel on cars with different kinds pendants. But if for some reason you haven’t come across or were not interested in the structure of the mechanism, then before buying a car, you should definitely drive at least a few kilometers in order to fully feel the pros and cons.

Torsion bar suspension parts price

Finding a car on a torsion bar suspension today is quite easy, most often it is installed as a rear axle for inexpensive front wheel drive vehicles... To understand how much the parts for repair cost, consider an example Renault kangoo.

Torsion bar parts prices Renault suspension Kangoo 2008
Name	Price from, rub. ($)
Torsion	6501 ($87)
Torsion bar holder	320 ($5)
Silentblock	320 ($5)
Rear spring	3810 ($51)

Despite the very simple design, the parts for the torsion bar suspension of the car are not that cheap. Accordingly, maintenance of the suspension is not the cheapest, especially when one of the torsion bars bursts.

Due to its size, the mechanism takes up little space, and according to the type of construction, some experts attribute it between dependent and independent suspension... Therefore, in some sources it is also called a semi-independent suspension. From the pros, you can note the smoothness and compactness, with the minuses, poor controllability and the possibility of failure of the torsion itself.

Rear torsion bar suspension repair video:

In this article we will talk about what a torsion bar suspension is, answer the question, what is its advantage, what material it is made of.

The material from which this type of suspension is made is called a torsion bar. It is a cylindrical rod made of metal. It is a very resilient material. The rod is made in stages so that it is of high quality and elastic. The steel undergoes a specialized heat treatment, and then the manufactured rod undergoes mechanical twisting.

One end of the torsion bar is attached to the frame of the machine, and the other is connected to the wheel hub. Today, in order for cars to drive well and overcome various impact obstacles (pits, bumps), in addition to the torsion beam, shock absorbers are additionally attached. This is necessary in order to increase the reliability of the connecting nodes.

This image shows a torsion beam

Principle of operation

We will describe in detail the principle of operation of the torsion bar suspension in this section. After one and the other end of the rod are rigidly fixed, when work is done, torsional forces act on the steel shaft. Since it is a very resilient and durable material, it bounces very well. When twisting occurs, the rod tends to return the wheel of the machine to its proper place.

In this picture we see a fragment of the work

Attention! To fully understand how this type of suspension works, you need to look clearly. Therefore, we have attached a video of the principle of operation of the torsion bar suspension:

Which suspension to choose

Very often, many people have a question: “What kind of suspension is better: torsion bar or spring?” In principle, both are good in terms of their parameters and are in great demand in the market. The main difference is the cost and its replacement in case of breakdown. The spring is much cheaper than the torsion bar and in maintenance too. The main part of the spring suspension is the springs, which makes the ride comfortable and improves the handling of the car, and the torsion bar, as we said above, is a steel rod. The advantage of the spring beam is that the coil springs are very light and you can arrange it as you like best and more conveniently, that is, for your car. But this does not mean that the torsion bar suspension has no advantages. We will talk about them further in our article.

In this photo we see a spring beam.

Benefits of torsion bar suspension

The main advantages of this type of suspension are as follows:

1. Sufficiently compact torsion bar suspension device.
2. Ease of repair and maintenance.
3. Suspension stiffness can be adjusted.
4. Smooth running of the car.
5. All mechanical vibrations of the frame and wheel are absorbed.

Of course, there are also disadvantages:

1. A very difficult rod manufacturing process.
2. The vehicle turns excessively when cornering.
3. There are needle bearings inside this structure. They stop working very quickly if dirt, dust and water gets there. If you do not service them for a long time, then soon you will have to completely change the entire structure.

Important! From all this, the following conclusion can be drawn: if you periodically inspect, fully service and perform high-quality diagnostics, then there should be no failures. Watch for serviceability.

Independent torsion bar suspension

In this section, we'll talk about the pros and cons of independent torsion bar suspension. There are several types of independent suspension:

1. MacPherson.
2. Torsion bar.
3. Multi-link.

Above, we have described in detail torsion view, and now let's talk about McPherson. The suspension is used for both the front and rear wheels... It has one wishbone at the bottom, instead of the second, a hinge-mount is used high under the wing on the mudguard of the wing-rack, which also acts as a shock absorber. Often springs are used in order to give elasticity, but some manufacturers also use a torsion bar. This is the main exception to the rule. Let's briefly talk about the pros and cons of McPherson. Pros: compact, lightweight, very reliable. Cons: Huge longitudinal vibrations. This type of construction is a very rigid frame. This frame is fitted with a swivel mechanism, which is held by means of a spring or spring. When the car hits a bump or falls into a hole, the slewing mechanism moves along the frame, thus providing a soft and comfortable ride.

In this image, we see an independent beam

Semi-independent torsion bar suspension

Semi-independent torsion bar suspensions are also very often used. The structure consists of two trailing arms connected by a U-beam. The whole structure will allow your car to overcome all the necessary obstacles, since the torsion work of such a suspension is very effective.

In this image, a semi-independent beam

Torsion bar suspension repair

As for the issue of maintenance and repair of the torsion beam, then it must be approached with special care, since the quality of the ride on your car depends on it. Before we consider questions about the repair block of problems, let's talk about adjusting the torsion bar suspension. Many are afraid that their beam is out of order, as it simply loosened. This is not at all true, and you should not be afraid of it. If the structure is loose, then you just need to adjust it using a key.

A warning! Be careful when making adjustments yourself. It is necessary to tighten the bolts so as not to overdo it. This is important to avoid unnecessary suspension stiffness.

It can also be noted that the torsion bar suspension is easier to adjust than the spring suspension.

Now let's go directly to the suspension repair and talk about the nuances and details that are important not to miss.

Attention: if you are unsure of your abilities and do not know all the nuances of repairing and adjusting suspensions, then do not get down to business to avoid troubles and breakdowns. In this case, you should contact the professionals. They will quickly and efficiently replace everything and carry out diagnostics.

If you, nevertheless, decided to independently adjust or repair the suspension, then read all the details, watch the training videos, and only then get to work. Here is a video to help you without special problems make high-quality diagnostics and replacement necessary spare parts torsion beam:

Important! Get down to business if the breakdown is minor, as otherwise, you will need to contact a car service.

Let us consider what phenomena can occur in the event of a breakdown or failure of individual spare parts:

1. If you hear a knock on the suspension while riding.
2. Rocking the car when cornering.
3. When driving straight ahead, the car will deviate to the side.

If you notice such phenomena behind your car, then you certainly need to repair the entire structure.

Important: supervise all the actions of a specialist.

If you took the car to a car service, you must do the following:

1. Inspect the suspension carefully.
2. Restore the beams.
3. Repair or replace, if necessary, the needle bearings and mounting pads.
4. Repair the shock absorber.
5. Change all levers.
6. Repair torsion bars.
7. Conduct a final inspection and make a diagnosis.

If you inspect, service and, if necessary, replace the necessary spare parts in a timely manner, then you will be guaranteed one hundred percent quality. In this article, we have described in detail the principle of operation, structure and advantages of some types of pendants, and the choice is only yours.

Good luck with your choice. Be careful and avoid cheating.
