Shock Absorber Action

The Absorber is used to suppress the shock of the spring after absorbing the shock and the impact from the road surface. It is widely used in automobiles to accelerate the attenuation of frame and body vibration to improve the ride comfort of automobiles. When passing through the uneven road surface, although the shock absorbing spring can filter the vibration of the road surface, the spring itself will also have reciprocating motion, and the shock absorber is used to inhibit this spring jumping

The shock absorber and the elastic element bear the task of shock mitigation and shock absorption, too large damping force will make the suspension elasticity deteriorate, and even make the shock absorber connector damaged. Therefore, it is necessary to adjust the contradiction between elastic elements and shock absorbers.
(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 role of the elastic elements and mitigate the impact. At this time, the elastic element plays a major role.
(2) In the suspension stretch travel (the axle and the frame are far away from each other), the damping force of the shock absorber should be large and the shock absorption should be rapid.
(3) When the relative speed between the axle (or wheel) and the axle is too large, 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 excessive impact load.
In the automotive suspension system is widely used in the cylinder shock absorber, and in the compression and stretch stroke can play a shock absorber called two-way acting shock absorber, and the use of new shock absorber, including inflatable shock absorber and resistance adjustable shock absorber.
