Shock absorbers (Absorber) are used to suppress the shock and impact from the road surface when the spring rebounds after absorbing shock. It is widely used in automobiles to accelerate the attenuation of frame and body vibrations to improve the driving smoothness of the car. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump.

The shock absorber can make the vehicle run smoothly. The shock absorber has the function of buffering vibration. Due to the structure of the vehicle shock absorber, the entire shock absorber will be compressed when the vehicle passes through a bumpy section, thereby compressing the external spring, but after the vehicle passes through a bumpy section, the elastic force of the spring will reset the shock absorber. There will be a hissing or hissing sound during the compression and reset of the shock absorber. We don’t need to panic, this is a normal phenomenon. In addition to this, the abnormal noise of the shock absorber needs our attention and treatment.
