Description

Technical Field

[0001] The utility model relates to the technical field of automobile shock absorbers, in particular to an adaptive automobile shock absorber. Background Art

[0002] In order to improve the comfort of the vehicle, leaf springs and shock absorbers are installed between the longitudinal beams and the suspension beams of the vehicle body as buffers. In existing automobiles, the most widely used is the hydraulic cylinder damping shock absorber; this type of shock absorber has a simple structure, low cost, and basically does not require maintenance.

[0003] Shock absorbers are mainly used to suppress the shock of the leaf spring rebounding after shock absorption and the impact from the road surface. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump. However, the damping force of the automobile shock absorber in the prior art is fixed and cannot be adaptively adjusted according to different road conditions. The damping force of the shock absorber is not matched, which affects the comfort of the vehicle. Therefore, it is necessary to propose an adaptive automobile shock absorber. Utility Model Content
