Rescue pillow - car suspension
Every year the number of car owners is swiftincreases. The world auto industry is an industry that has multiplied its capacities in a short time. There is nothing surprising. After all, now most of us choose road transport. Get the right - does not mean to understand the car.
Why in the technical specifications of anymachines, except engine power and body dimensions, the manufacturer always mentions the chassis? Everything is very simple. It is the suspension of the car that affects its stability and controllability. Plus, the chassis isolates the driver from vibrations, noise and other speed problems. In any case, the suspension of the car should keep the wheels well in close contact with the road. Why? The fact is that all the power that the motor gives out is transmitted to the tires of the car. Moreover, the suspension keeps passengers and cargo from damage. That is, it softens the blows. If our roads were perfectly even, then the running gear of the car would not be needed. But the realities of life dictate a completely different scenario. Even recently made trails are far from ideal. All small irregularities are transferred to the wheels of the car. Then the impact reaches the body, the cabin and the driver himself. To avoid such inconvenience, and was invented car suspension.
This mechanism is a chassis,which includes all important systems. Much of this depends on the stiffness of the wheel axles. Proceeding from this, two types of suspension are distinguished: dependent and independent. The first type is characterized by rigid coupling of both wheels of one axis. A solid beam forms. If you drive one wheel on a stone, then both will deviate to the same angle. Most often, such a construction is equipped with rear suspension of cars of economy class. This model of the chassis is quite cheap and durable, but it has a significant drawback. Most of the weight of the car is not transmitted to the shock absorbers of the undercarriage. In the case of an independent system, the wheels of one axis are not connected with each other. That is, when one wheel hits a bump, the second will not change its position. This suspension of the car has become more popular.
There is another type of car chassis. This is a semi-independent suspension. It is something middle between the two above mentioned species. The design includes longitudinal arms and a cross member between them. Only here the latter, unlike the rear suspension, is shifted closer to the levers and their supports. Thus, the cross member takes on not only the lateral forces, but also acts as a stabilizer of the car's movement. In this case, twisting is observed with a different direction of the wheels. If to look from the point of view of kinematics, the semi-independent suspension took from its "great-grandfathers" only the best qualities. The straight wheels do not get camber, and entering the turn the camber changes both relative to the road, and relative to the body. The simplicity of the construction plus excellent stability on the straight road and cornering made the semi-independent suspension popular among motorists.
Any design sooner or later comes out ofbuilding. In our case, the repair of the car suspension plays an important role. The thing is that this part of the vehicle takes on all the loads connected with the irregularities of our domestic roads. Accordingly, there is a rapid wear of the components of the suspension. Mechanical damage is the most common cause of its failure. When causing significant damage, the car will lose stability. The car will not obey the helm. Thus, riding will become life-threatening. In this case, immediately it is necessary to use highly qualified specialists, to diagnose, to identify faults and to eliminate them as soon as possible. Particular attention should be paid to shock absorbers. They are subjected to a tremendous load.
