Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a shock absorber with a centering wrist guard compression valve. Background Art

[0002] Automobile shock absorber is a damping element in the automobile chassis system. Its main function is to attenuate the vibration generated by the car during driving, thereby increasing the life of the car, enhancing the smoothness and riding comfort of the car during driving, and improving driving safety and operational stability.

[0003] A known authorized invention (publication number: CN209839044U) discloses a compression component of an automobile shock absorber, which includes: a wrist guard, a compensation valve spring, a compression valve body, a compression valve plate, a compression throttle valve plate, a compression valve seat and a piston rod, wherein the compression valve plate is sleeved on the compression valve seat, the compression throttle valve plate and the compression valve plate are installed together, and the compression valve body abuts against the combination of the compression valve plate and the compression throttle valve plate, so that the compression valve plate and the compression throttle valve plate are tightly together, so that the impact force from the piston rod can be buffered when the automobile shock absorber is working;

[0004] Although this shock absorber design can buffer the impact force of the piston rod to a certain extent, it does not form an effective cooperation with the damper during buffering, resulting in limited buffering effect. When faced with a large impact force, the buffering effect of this shock absorber is not ideal, which may cause unstable driving of the vehicle and even damage the vehicle structure. Therefore, we proposed a shock absorber with a centering wrist guard compression valve to solve the above problems. Utility Model Content
