Abstract

The invention discloses a piston rod assembly which comprises a piston rod, an adjustable bolt and a valve needle. At least one through hole is formed in the piston rod; the adjustable bolt is arranged in the piston rod; a channel is arranged in the adjustable bolt and communicates with the through hole in the piston rod; the valve needle is arranged at one end of the adjustable bolt; one end, faraway from the adjustable blot, of the valve needle is fixedly connected with a valve rod; one end, far away from the valve needle, of the valve rod is connected with an adjustable rod; and the adjustable rod is in threaded connection with the piston rod. Through adjusting a gap between the valve needle and the adjustable bolt, a specific value of a damping force is adjusted through controlling the oil capacity, so that the shock absorber can adapt to different road conditions, and the comfort in driving is realized.

Description

technical field [0001] The invention relates to the technical field of vehicle parts, in particular to a piston rod assembly of a shock absorber. Background technique [0002] In order to increase the comfort of the vehicle, the chassis system of the car uses a shock absorber for shock absorption and buffering. The shock absorber is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will reciprocate, and the shock absorber is used to suppress this jump. The shock absorber relies on damping force to suppress the jump of the spring. The damping of the common shock absorber cannot be adjusted, so it cannot be well adapted to various road conditions. For many vehicle enthusiasts, it is impossible to enjoy the corresponding fun. [0003] Therefore, a shock absorber adaptable to diffe...
