As an important part of the car's suspension system, the role of shock absorbers cannot be ignored. In addition to the driver's operation, whether a driving car is stable and whether the people in the car is comfortable or not depends largely on the quality of the shock absorber.
The shock absorber is mainly used to suppress the shock and the impact from the road surface when the spring rebounds after absorbing the shock. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will reciprocate. The shock absorber is used to restrain this kind of spring jumping. If the shock absorber is too soft, the body will jump up and down. If the shock absorber is too hard, it will bring too much resistance and prevent the spring from working properly. In the process of modifying the suspension system, hard shock absorbers should be matched with hard springs, and the hardness of the spring is closely related to the weight of the car. Therefore, heavier cars generally use harder shock absorbers.
