Abstract

The invention discloses a valve structure of a damper, and the valve structure control damping forces under a low amplitude and a high amplitude respectively when a piston valve is compressed and expands, thus satisfying driving comfortability and stability of a vehicle. The damper comprises a cylinder filled with working fluids and comprises the piston rod, one end of the piston is positioned in the cylinder and the other end extends to outside the cylinder, and the valve structure of the damper comprises a main piston valve assembly which is mounted on one end of the piston rod and operates in the circumstance that an inner part of the cylinder is divided into an upper chamber and a lower chamber to generate a damping force based on changes of the movement speed, and a subsidiary piston valve assembly which moves together with the main piston valve assembly to generate a damping force based on frequency changes.

Description

technical field [0001] Embodiments of the present invention relate to a valve structure of a shock absorber, which respectively controls the damping force at low amplitude and high amplitude when the piston valve is compressed and expanded, thus satisfying the driving comfort of the vehicle at the same time sex and stability. Background technique [0002] Generally, a damper device is installed on a vehicle, which absorbs shock or vibration applied to an axle from a road surface during driving to improve driving comfort, and a shock absorber is used as one such damper device. [0003] The shock absorber operates according to vehicle vibration corresponding to the state of the road surface, and the damping force generated from the shock absorber varies according to the operating speed of the shock absorber, ie, whether the operating speed of the shock absorber is high or low. [0004] By adjusting the damping characteristics generated from the shock absorbers, the ride comfo...
