Automobile shock absorber is an important part of automobile suspension system. Its function is:

1. In order to rapidly attenuate the vibration of the frame and body and improve the ride comfort and comfort of the vehicle, the vehicle suspension system is generally equipped with shock absorbers, and the two-way acting cylindrical shock absorbers are widely used in the vehicle. Shock absorber is a vulnerable part in the process of automobile use. The working quality of shock absorber will directly affect the stability of automobile driving and the service life of other parts. Therefore, the shock absorber should always be in good working condition.

2. The shock absorber can make the vehicle run smoothly. The shock absorber has the function of cushioning vibration. If the shock absorber is missing in the suspension, the car will run unsteadily and shake. Now many automobile shock absorbers are hydraulic shock absorbers. Its principle is to fill a cylinder drilled with a small hole and equipped with a piston with pressure oil. When the spring vibrates, the oil will be forced to flow through the small hole, so it has a limiting effect. The size of the small hole diameter determines the role of the limit. If the diameter of the small hole is small, there are strong restrictions and the vehicle stability will be high; On the contrary, the car feels more comfortable. When designing, the size of the small hole diameter should give consideration to stability and comfort.
