Problems solved by technology

However, the inner valve cylinder and the outer valve cylinder of this adjustable damping valve are connected by extrusion deformation, which is difficult to process. Adjustable damping valve can only provide 4 kinds of fixed damping coefficients, and cannot realize continuous control of damping coefficients

Abstract

The invention discloses an electricity proportion type damping regulating valve for a shock absorber which comprises a valve seat A, a damper valve A, a damper valve B, a damper valve cylinder, a hinge pin and a valve seat B; the hinge pin is installed in the damper valve cylinder in the axial mode and the two ends of the hinge pin are supported by the valve seat A and the valve seat B; the damper valve A and the damper valve B are installed on the hinge pin and separated by a locating sleeve A, a locating sleeve B and a locating sleeve C; a circular hole A is arranged in the axial center of the damper valve A; a L-shaped hole is respectively arranged in the two sides of the circular hole A, however, the directions of the two L-shaped hole structures are opposite, a valve plate a and a valve plate b are installed at the two sides of the damper valve A; and the damper valve cylinder is arranged at the outer side of a damper cylinder and connected with the damper cylinder in the fixed mode through a transition block. The electricity proportion type damping regulating valve for the shock absorber is capable of effectively achieving ratio control on damping coefficient of the damping regulating valve, improving the boundedness in damping coefficient adjustment in the prior art, optimizing and integrating the integrated structure of the damping regulating valve, and improving the manufacturability of processing and assembling.

Description

technical field [0001] The invention relates to a damping regulating valve for an automobile shock absorber, in particular to an electric proportional damping regulating valve for the shock absorber, which is suitable for continuous adjustment of the damping of the automobile shock absorber and belongs to the technical field of fluid and automation control. Background technique [0002] The automobile vibration damping system is the connecting mechanism between the vehicle suspension and the chassis, and it is the link to control the up and down vibration of the automobile. When the car is running, the piston rod of the shock absorber reciprocates, and the oil circulates back and forth between the recovery chamber and the compression chamber of the piston through a series of damping valve holes. During the cycle, the damping coefficient of the damping valve hole determines the damping effect of the car. [0003] So far, the application number is CN104482101A Chinese patent ...
