1, shock absorber, which is used to suppress the vibration when the spring bounces after shock absorption and the impact from the road surface. It is widely used in automobiles to accelerate and attenuate the vibration of the frame and body and improve the ride comfort of automobiles. When passing through the uneven road surface, although the damping spring can filter the vibration of the road surface, the spring itself will reciprocate, and the shock absorber is used to suppress this spring jump.
2. In the suspension system, the elastic element is impacted and vibrates. In order to improve the ride comfort of the car, the shock absorber is installed in parallel with the elastic element. In order to attenuate vibration, most of the shock absorbers used in automobile suspension system are hydraulic shock absorbers. Its working principle is that when the frame (or car body) and the axle vibrate and have relative motion, the piston in the shock absorber moves up and down, and the oil in the shock absorber cavity repeatedly flows from one cavity to another through different holes.
3. Shock absorbers and elastic elements undertake the tasks of shock absorption and shock absorption. Excessive damping force will make the suspension elasticity worse and even damage the shock absorber connector. Therefore, it is necessary to adjust the contradiction between elastic elements and shock absorbers.
