Suspension of any vehicle is always the first to take a blow from irregularities on the road. For optimal perception of these irregularities, it is equipped with elastic elements, which using a transverse beam, redistributing the accepted efforts, shift the wheels. This system, which consists of levers and beams, is called a transverse stability stabilizer. Its appointment is to maintain the stability of the car during corners or other external efforts.

Car suspension, device and principle

Common elements for all types of suspension are:

1. Power distribution components.
2. Components of ensuring elasticity.
3. Components of transverse stability stabilization.
4. Quenching component.
5. Fasteners

Components of ensuring elasticity They are a kind of buffer between the vehicle body and road irregularities. This includes torsion bars, springs and coil springs. The springs are of variable rigidity and constant. Suspension is a set of elastic strips of metal which are tightened kind of "ladder" and have different lengths. Torsion bars are a metal pipe in which the rods are functioning according to the principle of twisting.

There is another type of elastic components - hydro-pneumatic and pneumatic. The first is a symbiosis of compressed air and working fluid in one chamber, which is divided by a partition, a second action based on compressed air properties.

The components of the distribution direction of the force simultaneously serve for fastening the suspension to the car body, force transmission body and proper location of the vehicle wheels relative to the body horizontally and vertically. Data features include a double leverage, leverage the longitudinal and transverse installation.

extinguishing components (Dampers) are used to counteract the elastic components, namely for smoothing fluctuations. Structurally, the shock absorbers are in the form of a metal tube with fixing elements and apply the principle of the hydraulic resistance. There are two types of shock absorbers - monotube and twin tube. According to the method steps are shock absorbers, oil, pneumatic and gazomaslyanye.

Components stabilizing transverse stability - bar with fixing pillars to the car body, which connects the levers opposite wheels. The components are designed to reduce roll and lateral distribution of the load of the car when cornering.

Fastening suspension components vehicle to the body and supports the wheels is performed via bolted connections, ball joints and rubber bushes (rubber plugs).

Anti-roll bar, the place of installation, the device is assigned the task

Anti-roll bar is easy to see, if you put the car on a viewing hole or drive to the ski lift. On the front axle, including shock absorbers, springs and other levers you will notice a curved steel rod, which at its one arm is attached to the wheel hub, and the other - the subframe. fastening of the stabilizer are not rigid and allowed to move around in the same plane as the axis.

The principle of operation of the stabilizer based on the redistribution of the weight of the vehicle body on wheels under the appearance of the roll. For example, during a sudden change of trajectory driving and cornering with a small radius.

stabilizer bushings, why they break down, signs of destruction

For the maximum desired vibration damping and force effects that go to the vehicle body, the vast majority of suspension components connected by means of elastic elements. This applies to the anti-roll bar. special bushings are used to secure it (cushion gum), polyurethane or hard rubber.

Under the influence of time and a variety of factors, such as the poor state of the road surface, the use of aggressive reagents, driving style, and so on, data of the sleeve can begin to break down. As a result of this work the stabilizer becomes unsatisfactory. They may also begin to arise more serious defects.

The first symptom, boding replacement bushings - a slight knocking suspension. Such hammering can also be heard at the "tired" dampers. However, in the case of the bushes, he will be heard not only in the pits and potholes, but also when entering the sharp turns. The vehicle is not seldom felt too sluggish and rolls. Emerged knock will result appeared backlash in the connection units levers stabilizer because of wear sleeves.

Risk of faulty operation of the vehicle with bushings stabilizer

If you do not take action in time in the future knocks only be strong, and must accompany the work suspension due to the increasing destruction and bushings strain. It may be excessive play and steering cross-pitching of the body. Perhaps the "yaw" of the vehicle not only when cornering, and in the case of rebuilding or braking. Automakers usually recommend changing sleeve every thirty or forty thousand run. But in our conditions, it is desirable to focus on their wear. Therefore, suddenly appeared light chatter and clatter when cornering are clear symptoms of impending replacement of elements.

How to check the quality of bushings

There is a people's way to check the bushings of the stabilizer in good condition. It is necessary to drive a lying policeman "Decion" on the second gear. In the area of \u200b\u200bthe pedal, there was a deaf knock - most likely, the bushings were worn out. You can also just climb under the car and see everything yourself. On the worn sleeve, cracks and scuffs will be noticeable, which are characteristic of lightering and worn rubber. Sometimes the automaster also calls such cracks with "daisies".

In addition, the rubber of the sleeves can simply cry and lose the desired elasticity. If it does not work normally consider the sleeve, shake the stabilizer itself. The presence of a backlash, squeaks and knocks in the lower part of the suspension indicates that the stabilizer bushings were unusable.

Tools, fixtures, consumables

1. Caid head.
2. Gorog.
3. Ratchet with extension.
4. Rozhki and precipitant keys.

Replacing cross-stability sleeves with their own hands (step by step)

1. It is necessary to post a car on jacks and secure securely.
2. Next, remove the wheels.
   
3. Remove the protection of the crankcase and the sneakers.
4. Lift the bottom lever using the jack or put the focus on it. In the case of replacing the bushings from both wheels, it is desirable to put the stops under the an axis of the front wheels or take advantage of the jack. It is necessary to remove the load from the beam of the stabilizer and facilitate the further replacement of the sleeves.
   
5. Then loosen the fastening of the stabilizer to the subframe or body (on both sides). If there are difficulties with bolts as a result of their oxide and contamination, process them with "WEDEshka" or other similar solutions to facilitate their unscrewing.
6. Remove the fastening of the sleeve and the sleeve itself. To date, the bushings often make split, which significantly facilitates the procedure for their dismantling.
   
7. Take a new sleeve and set the old one. Well wash and wipe the seat of the element on the stabilizer. You can also wash the sleeve a little to make it more convenient to move it or use the special lubricant that does not rarely go in Remkomplekt.
   
8. Tighten the fastening bolts of the sleeve clamp.
   
9. Remove the jack from the lever and install the wheel.

Tips Prof.

It should be understood that the suspension device on various cars can differ significantly and this instruction is not universal. However, for the general understanding of the procedure and the procedure for performing work, it is quite enough.
