Electronic control shock absorber

Abstract

The invention relates to an electronic control shock absorber which comprises a working cylinder at the inner layer, an oil storage tank at the intermediate layer, an outer cylinder sleeve at the outer layer, a piston, a piston rod, an upper electromagnetic valve, a lower electromagnetic valve, an upper check valve, a lower check valve, a shock-absorbing spring, an upper cavity and a lower cavity, wherein the piston is arranged in the working cylinder; the piston rod shifts up and down along with the piston; the upper / lower electromagnetic valve is positioned at the top / bottom end of the working cylinder to communicate or close the working cylinder and the oil storage tank; the upper / lower check valve is positioned between the upper / lower electromagnetic valve and the piston; one end of the shock-absorbing spring is connected with the upper end of the oil storage tank, the other end of the shock-absorbing spring is connected with the upper end of the outer cylinder sleeve; the upper / lower check valve is communicated with or closes the upper / lower chamber of the oil storage tank and the working cylinder through opening or closing; the lower end of the outer cylinder sleeve issealed by an end cover; and the piston rod extends out of the lower electromagnetic valve and is fixedly connected with the end cover to drive the outer cylinder sleeve to shift up and down. The electronic shock absorber provided by the invention has 4 working states (free stretching, only stretch but no contract, only contract but no stretch, no stretch and contract), has a simple structure, hasthe same overall dimension with the shock absorber, has low cost and reliable performance, the requirement of travelling comfort and control stability for the shock absorber of an automobile can be considered.

Description

technical field [0001] The present invention relates to a shock absorber, and more particularly to an electronically controlled shock absorber. Background technique [0002] Cars have gradually become a part of people's lives. As a means of transportation, people hope that the car has good ride comfort to slow down the bumps of the car on uneven roads. At the same time, they also hope that the car has good handling stability to prevent the car The quality of the car suspension system plays an important role in ensuring ride comfort and handling stability when the car body tilts and shakes during acceleration or deceleration braking at a start and high-speed cornering. The automobile suspension system is an elastic structure connecting the wheels and the body, and one of its main components is the damping shock absorber. The damping shock absorber cooperates with the elastic element to play the role of buffering, reducing vibration and maintaining the stable posture of the v...
