Piston valve system, shock absorber provided with piston valve system and vehicle

Abstract

The invention discloses a piston valve system, a shock absorber provided with the piston valve system and a vehicle. The piston valve system comprises a piston rod and a valve plate assembly. A valve plate deformation supporting part and a valve plate inner supporting part protruding downwards are formed on the lower end face of the piston rod, a valve plate shaft is arranged at the position of the valve plate inner supporting part, and the valve plate deformation supporting part is located on the periphery of the valve plate inner supporting part. The valve plate assembly is arranged on the valve plate shaft in a sleeving manner and provided with a compression valve plate, the compression valve plate comprises a compression joint part in compression joint with the valve plate inner supporting part and a deformation part located on the periphery of the compression joint part, and the deformation part is provided with a deformation position making contact with the valve plate deformation supporting part and a free position separated from the valve plate deformation supporting part. According to the piston valve system, the function of a compression supporting block used for supporting the compression valve plate is integrated at the lower end of the piston rod, and therefore the number of components of the piston valve system can be reduced, the axial length and weight of the piston valve system can be reduced, and it is guaranteed that the piston valve system is simple in structure, compact and low in cost.

Description

Technical field [0001] The present invention relates to the field of damper, and in particular, in particular, a piston valve system and a damper and a vehicle mounted with the piston valve. Background technique [0002] The piston valve system in the current damper is typically disposed in each of the two ends of the valve assembly, which results in a redundancy increase of the piston valve system, and the axial length of the piston valve and increases by weight. And as the time to the damper is increased, the valve is deformable, resulting in deterioration of the performance of the damper, affecting the manipulation stability of the vehicle. Inventive content [0003] The present invention is intended to solve one of the technical problems in the prior art at least to some extent. To this end, the present invention proposes a piston valve, which integrates a valve support block to ensure a compact structure of the piston valve, and has high work reliability. [0004] The prese...

AI Technical Summary

Problems solved by technology

[0002] The piston valve system in the current shock absorber is generally provided with a valve plate support block at both ends of the valve plate assembly, which will lead to an increase in the redundancy of the piston valve system, an increase in the axial length and weight of the piston valve system

And as the shock absorber is used longer, it will also lead to deformation and failure of the valve plate, which will lead to the deterioration of the performance of the shock absorber and affect the handling stability of the vehicle.
