Universal shock absorber valve seat and shock absorber

Abstract

The invention relates to a universal shock absorber valve seat and a shock absorber. A shock absorber valve seat body is of a hollow cylindrical structure with the upper end closed, a piston rod penetrating hole is formed in the center of the upper end face of the shock absorber valve seat body, three concentric circular-ring-shaped protruding structures are arranged on the outer side of the piston rod penetrating hole, and are respectively a first circular ring protrusion, a second circular ring protrusion and a third circular ring protrusion, through holes penetrating through the upper end face are evenly distributed between the first circular ring protrusion and the second circular ring protrusion, throttling holes are formed in the positions, outside the first circular ring protrusion and the second circular ring protrusion, of the through holes, and the height of the first circular ring protrusion and the height of the third circular ring protrusion are the same and are both larger than the height of the second circular ring protrusion. According to the shock absorber valve seat technology of the technical scheme, generalization is achieved, the damping adjusting range is enlarged, shock absorber valve seats can be completely the same even if damping forces of different vehicle types or vehicle types with different configurations are different, and the cost of production management and the like is reduced.

Description

technical field [0001] The invention belongs to the technical field of shock absorbers, and in particular relates to a generalized shock absorber valve seat and a shock absorber. Background technique [0002] The damping characteristic of the shock absorber is one of the important characteristics of the shock absorber, which directly affects the handling, comfort, NVH and safety of the car. Different cars require different damping characteristics, and even different configurations such as the powertrain of the same car have different damping characteristics. Therefore, the adjustability and differentiated damping characteristics of the shock absorber are highly required. There are not many types of damping adjustment structures used for shock absorber valve systems, but the differences are quite large. In terms of damping adjustment methods, there are mainly: one is to rely on the variable stiffness limit spring to change the hydraulic flow and flow speed to realize hydrau...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a generalized shock absorber valve seat and shock absorber to solve the problem that the damping adjustment range of the existing shock absorber valve seat is small, and different vehicle models use a kind of shock absorber valve seat, which leads to vibration reduction. There are many types of valve seats, which is not convenient for production consistency control
