Damping Adjustment for Different Strokes

Compression stroke: When 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 elements play a major role.
Stretch stroke: When the axle and frame are far away from each other, the damping force of the shock absorber should be large, and the shock should be rapidly absorbed to prevent the excessive spring rebound resulting in vehicle turbulence.
Automatic adjustment during high-speed movement: when the relative speed between the axle (or wheel) and the axle is too large, the shock absorber can automatically increase the liquid flow, so that the damping force is always kept within a certain limit to avoid excessive impact load.
