The car must be comfortable and safe. Must move evenly. Resist tipping and cornering. To achieve such indicators, there are many different ways. Now we will talk about the anti-roll bar and its elements in the car's suspension system .
Surely, each driver has repeatedly noticed that the car rolls sideways when cornering. Another car, on the contrary, as if clinging to the roadway with tires, passes a turn without unnecessary rocking.
Of course, a lot depends on the type and design of the suspension. And by the way, from series to series, it is undergoing significant changes. It should be noted that for a comfortable ride, the suspension should be soft. But there are many drawbacks to softness. One of them is rocking the body. To prevent this phenomenon, designers can go for various tricks. About it further.
Installing a stabilizer allows the suspension to be a little stiff, to keep the car from swinging excessively while maintaining comfortable driving characteristics. The stabilizer bushings actively help him in this.
The stabilizer is made in the form of a metal bar and has spring properties. The front stabilizer bushings are mounted approximately in the middle (depending on the design) and are made of rubber.
In the middle part, the stabilizer is attached to the body or beam. It has a U-shape. The ends, through the hinged racks (popularly called the bones), are attached to the suspension elements, more often to the levers.
Now consider what a sleeve is. Bushing, in the context of a stabilizer, is an interfaced part. That is, it is worn on the part with its internal hole (an example is a hand grip), fasteners are placed on it from the outside and screwed to a rigid element (in our case, the car body or the suspension beam). Result: the stabilizer is fixed rigidly, but thanks to the bushings it has the ability to "swim", performing its working functions.
The stabilizer bushings can annoy with an unpleasant knock when worn. How to avoid this?
The lateral stability of the car is extremely important, especially when cornering. If, for example, you do not take into account the rate of entry into a turn, the machine can easily roll over. Of course, if driving a “daredevil”, a car may not be able to save even the most modern-day stability control systems. When changing the trajectory of movement, the machine leans in the direction opposite to the turn. There is a risk of tipping over. In this case, one wheel is more loaded than the other. From this it follows that a more loaded wheel must be "supported". This function is assigned to the stabilizer. The stabilizer bushings, in turn, provide it with a "floating rotation" to prevent rupture of the metal from overload.
The stabilizer is a very reliable element in the suspension of the car. Since it perceives variable loads, the parts associated with it wear out. It is advisable to replace the defective parts with new ones at the next maintenance, without waiting for their complete destruction. Stabilizer bushings, subject to their proper quality, serve for a long time, about 10,000 km. But they can remind of themselves before with a characteristic creak and knock. You do not need to be scared! But delaying the solution of the issue is also not worth it. You can replace the stabilizer bushings yourself. High qualification and rich locksmith experience is not required. But be sure to read the manual for car repair. It is also equally important to find and purchase high-quality bushings, thereby eliminating the likelihood of premature wear.
