Background

The shock absorber is an apparatus for accelerating the attenuation of the vibration of a frame and a vehicle body so as to improve the running smoothness (comfort) of the vehicle, and is arranged in a suspension system of most vehicles. The shock absorber used on the automobile comprises 3 types of bidirectional cylinder shock absorbers, inflatable shock absorbers and damping adjustable shock absorbers.

A vibration damper for a motor vehicle is a vibration damper which is used not only in suspension systems but also in the driver's cab, the vehicle seat, the steering wheel, etc., and also as a damper in the vehicle bumper. When the frame and the axle reciprocate relative to each other and the piston in the shock absorber also reciprocates in the cylinder, oil in the shock absorber housing repeatedly flows from one chamber to the other chamber through narrow apertures. At the moment, the friction between the hole wall and the oil liquid and the friction in the liquid molecules form damping force to the vibration, so that the vibration energy of the vehicle body and the vehicle frame is converted into heat energy, absorbed by the oil liquid and the shock absorber shell and then dissipated into the atmosphere.
