Abstract

The invention relates to a damping regulating valve for a shock absorber. The damping regulating valve mainly comprises piston rods, limiting blocks, a valve plate group, a piston, springs, spring positioning seats, a fastening nut, a throttle valve core, sealing rings and the like. The valve can be applied to single-cylinder shock absorbers and double-cylinder shock absorbers. The throttle valvecore installed in the piston automatically senses road surface vibration and automatically switches to a suitable damping value. The damping characteristic of the shock absorber equipped with the damping regulating valve automatically changes with the driving condition, and the steplessly adjustable function and the wide adjusting range are realized, so that a vehicle has excellent smoothness andmaneuverability; and meanwhile the damping regulating valve has the beneficial effects of being simple in structure, sensitive in response, high in reliability, free of sensors and power sources, lowin cost and the like.

Description

technical field

[0001] The invention relates to a damping regulating valve which can be used in the field of single cylinder and double cylinder shock absorbers, in particular to a damping regulating valve of the shock absorber which can change the damping characteristics of the shock absorber according to the working conditions. Background technique

[0002] The driving comfort and safety of a car are a pair of natural contradictions. Comfort requires the shock absorber to provide a softer damping force, while driving safety requires the shock absorber to provide a larger damping force. When the up and down movement speed of the suspension is high and the acceleration is high, the damping is required to be large; when the suspension is moving up and down at a low speed and the acceleration is small, a small damping is required so that the vehicle has better driving comfort and manipulative. When traditional passive shock absorbers face this contradiction, they often can on...
