Abstract

The invention relates to the technical field of shock absorbers, in particular to a passive adjustable damping force shock absorber and an automobile, and aims to solve the problem that the overall structure of an existing shock absorber is very complex in order to realize damping change. In order to achieve the purpose, the shock absorber comprises a cylinder barrel, a piston, a piston rod, a first flow adjusting valve, a second flow adjusting valve and a guide structure, wherein the first flow adjusting valve is rotationally arranged on a first valve structure, and the second flow adjusting valve is rotationally arranged on a second valve structure; and the guide structure is arranged to enable the first flow adjusting valve to rotate relative to the first valve structure and enable the second flow adjusting valve to rotate relative to the second valve structure in the compression stroke and the stretching stroke of the shock absorber, and then the damping force of the shock absorber is adjusted. Passive adjustment of damping force under different strokes can be achieved by adding a simple structure, the complexity of structural design is reduced, and the compression and stretching stability of the shock absorber can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, and specifically provides a passive adjustable damping force shock absorber and an automobile. Background technique [0002] Shock absorber is a common component to realize the function of vibration reduction. It is widely used in various fields. For example, in automobiles, shock absorbers, as an important part of the suspension system, can improve the ride comfort and ride comfort of the car. For example, in The shock absorber is connected to the structure of the frame and the axle. When the frame and the axle reciprocate relative to each other, the piston of the shock absorber also reciprocates in the cylinder, and the oil in the cylinder of the shock absorber repeatedly moves. At this time, the friction between the hole wall and the oil and the friction between the liquid molecules can form a damping force on the vibration, so that the vibration of the body and the frame The energy i...
