Abstract

The invention discloses a bottom valve assembly of a shock absorber. The bottom valve assembly comprises a valve seat, a circulation valve plate arranged at the left side of the valve seat, and an adjustable valve plate arranged at the right side of the valve seat. The left side and the right side of the valve seat are each provided with two layers of valve lines, namely the outer valve line and the inner valve line, wherein the height of the outer valve lines at the left side and the right side is larger than that of the corresponding inner valve lines. The outer valve lines and the inner valve lines of the valve seat have a certain height difference, the width of the end face of each valve line is reduced, and therefore the quality and the product percent of pass of the bottom valve assembly are improved, and the usability of the shock absorber is improved.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a novel shock absorber bottom valve assembly structure. Background technique [0002] With the continuous improvement of people's requirements for the comfort of automobiles, the performance and quality requirements of automobile shock absorbers are also higher and higher. At present, the composite gas-filled two-way hydraulic shock The structure can adjust the damping force required by the main engine factory, so that the shock absorber can achieve a good vibration reduction effect, and at the same time, it can better eliminate the distortion of the external characteristics and achieve better NVH performance. To improve the damping effect of the shock absorber, it is necessary to continuously debug the structure of the shock absorber valve system. The existing shock absorber bottom valve assembly is usually composed of a valve seat and a valve plate. The damping force i...
