Problems solved by technology

[0003] In order to solve the problem that the piston valve seat of the shock absorber in the prior art is in use, because the space of the fan-shaped lower platform cannot support the valve plate, the valve plate is easily deformed and fatigued, thereby affecting the use effect and service life of the shock absorber. Problem, the present invention proposes a shock absorber piston valve seat with bumps

Abstract

The invention provides a shock absorber piston valve seat. The two end faces of the shock absorber piston valve seat are respectively provided with a plurality of bosses with the same number and a plurality of fan-shaped low tables between the bosses, and the heights of the table tops of the bosses are consistent with the heights of the end faces of the valve seat. Forward normally-through holes penetrate through the bosses on one end face and the fan-shaped low tables on the other end face, reverse normally-through holes penetrate through the fan-shaped low tables on one end face and the bosses on the other end face, protruding points are evenly distributed on the multiple fan-shaped low tables on the two end faces of the valve seat, and the heights of the protruding points are consistentwith the heights of the table tops of the bosses. The positions of the protruding points do not coincide with the positions of the forward normally-through holes and the reverse normally-through holes. In the working process of the shock absorber piston valve seat, when valve plates located on the two end faces of a piston are stressed, the protruding points and the bosses can abut against the valve plates at the same time, bending deformation of the valve plates is reduced, the valve plates are not prone to fatigue or deformation, the service life of the valve plates can be prolonged, and normal use of a shock absorber is guaranteed.

Description

technical field [0001] The invention relates to the field of shock absorbers, in particular to a piston valve seat of a shock absorber. Background technique [0002] In the prior art, both ends of the shock absorber piston valve seat are provided with a plurality of bosses and fan-shaped low platforms between the bosses. , the boss and fan-shaped low platform on both ends are staggered, the forward normal through hole penetrates the boss on one end surface and the fan-shaped low platform on the other end surface, and the reverse normal through hole penetrates the fan-shaped low platform on one end surface and the other end surface boss settings. When the piston moves down in the cylinder, the valve plate close to the lower end of the piston will cover the positive normal through hole, while the reverse normal through hole is unblocked. When the piston moves up in the cylinder, the valve plate close to the upper end of the piston will The reverse normal through hole is cove...
