Background
The shock absorber is used for inhibiting vibration and impact from road surface when the spring rebounds after absorbing the vibration. The damping device is widely used for automobiles, and is used for accelerating the damping of the vibration of the frames and the automobile bodies so as to improve the running smoothness of the automobiles.
While the shock absorbing spring can filter the shock of road surface when passing over uneven road surface, the spring itself can reciprocate, and the shock absorber is used to restrain the spring from jumping. The shock absorber is too soft, the automobile body will jump from top to bottom, and too hard of shock absorber will bring too big resistance, prevents the spring normal operating. In the modification of suspension systems, the hard shock absorber is matched with the hard spring, and the hardness of the spring is closely related to the vehicle weight, so that the heavier vehicle generally adopts the hard shock absorber to restrain the shock and the impact from the road surface when the spring bounces after absorbing the shock.
