Abstract

The application relates to a shock absorber with variable damping according to the strength of the road surface, belonging to the technical field of automobile shock absorbers, including: a working cylinder with a piston and a piston rod inside, and the piston divides the working cylinder into an upper chamber and a lower chamber One end of the piston rod is connected with the piston and drives the piston to reciprocate in the working cylinder; the plunger rod moves inside the piston rod, the piston rod is provided with a first channel, and the plunger rod is provided with a second channel, when the plunger When the rod moves to a set position in the piston rod, the upper chamber and the lower chamber communicate through the first passage and the second passage. In the shock absorber of the present application, a plunger rod is added in the piston rod, and the plunger rod moves adaptively in the piston rod according to different road conditions and driving states of the vehicle to adjust the damping force of the shock absorber. The plunger rod of the present application is a passive adjustment element, which can adaptively adjust the damping force of the shock absorber without external control, improves the reliability of the shock absorber, and reduces the manufacturing cost.

Description

technical field [0001] The present application relates to the technical field of automobile shock absorbers, in particular to a shock absorber with variable damping according to road surface strength. Background technique [0002] In the vehicle suspension system, the main function of the shock absorber is to accelerate the attenuation of the vibration of the frame and the body to improve the ride comfort of the vehicle. For automobiles, excellent ride comfort and operational stability are crucial, and the important component that affects the characteristics of the suspension system is the shock absorber, so the ideal damping adjustable shock absorber can improve the ride comfort and stability of the car. ride comfort. [0003] There are many principles, structures, and adjustment methods to realize the adjustable damping of the shock absorber, and the performances are different. The damping coefficient of the hydraulic shock absorber can be adjusted by changing the viscos...
