In order to accelerate the attenuation of the vibration of the frame and the body to improve the ride comfort (comfort) of the car, shock absorbers are installed inside the suspension system of most cars.
The shock absorption system of a car is composed of springs and shock absorbers. The shock absorber is not used to support the weight of the body, but is used to suppress the shock when the spring rebounds after shock absorption and absorb the energy of road impact.
