Abstract

The invention relates to an electric control variable damping shock absorber for vehicle debugging, which comprises an upper lifting lug, a piston assembly, a dust cover, an oil seal, an upper magnet exciting coil, an oil cylinder barrel, an upper oil cavity, an oil inlet valve, a lower oil cavity, a lower magnet exciting coil, a transition cylinder barrel, a pressure sensor, a lower lifting lug, an oil return valve, an oil storage cavity, a compression valve, a speed sensor transmitting end, a compensation valve and a speed sensor receiving end, the shock absorber is used for being arranged on an automobile suspension or the upper position and the lower position of the suspension, the non-stop damping force can be adjusted according to the smoothness performance condition of an automobile, and the driving smoothness of the whole automobile is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile suspension design, in particular to an electronically controlled variable damping shock absorber used for vehicle debugging. Background technique [0002] Whether the design of automobile suspension or suspension is reasonable or not is one of the key factors affecting the ride comfort of the vehicle, especially the adjustment of the damping characteristics of the shock absorber is of great significance to improve the ride comfort of the vehicle. [0003] For OEMs, it is an indispensable link in the vehicle test stage to determine the optimal damping characteristics according to the test results by replacing shock absorbers with different damping characteristics. The contradiction between the number of vibrator samples and the calibration accuracy led to an increase in the test cycle. Contents of the invention [0004] The invention discloses an electronically controlled variable damping sho...
