Shock absorber is used to restrain the shock of spring after the rebound and the impact from the road. Widely used in automobiles, for accelerating the attenuation of frame and body vibration, in order to improve the ride smoothness of cars. The shock-absorbing spring filters the vibrations of the road when it passes through rough roads, but the spring itself moves back and forth, and the shock absorber is used to keep the spring from jumping.
This suspension provides a smoother ride and better overall damping management
Working principle :
(1) in the compression stroke (the axle and frame are close to each other), the damping force of the shock absorber is small, so as to give full play to the elastic effect of the elastic components and mitigate the impact. At this point, the elastic element plays a major role.
(2) in the stretching travel of suspension (the axle and frame are far away from each other), the damping force of shock absorber should be large, and the shock absorber should be rapid.
(3) when the relative speed between vehicle bridge (or wheel) and vehicle bridge is too high, the shock absorber is required to automatically increase the liquid flow so that the damping force is always kept within a certain limit to avoid bearing too large impact load.
