Title:
ELECTRICALLY CONTROLLED HYDRAULIC/PNEUMATIC SUPPORT SHOCK ABSORBER
Document Type and Number:
WIPO Patent Application WO/2020/199754
Kind Code:
A1
Abstract:
Provided is an electrically controlled hydraulic/pneumatic support shock absorber. An electronic control valve (11) is connected between a hydraulic cylinder (10) and a hydraulic/pneumatic accumulator (2), and the pressure in the hydraulic cylinder, i.e. the support force value of the hydraulic cylinder, is controlled by damping values of the hydraulic/pneumatic accumulator and the electronic control valve. A detection device (15) for detecting the liquid flow direction is provided between the hydraulic cylinder and the hydraulic/pneumatic accumulator to detect, in real time, whether the liquid flow flows from the hydraulic cylinder to the hydraulic/pneumatic accumulator or from the hydraulic/pneumatic accumulator to the hydraulic cylinder. A force measurement element (13) measures the real-time support force value of the support shock absorber. A control assembly (6) compares the measured real-time support force value of the support shock absorber with the desired optimal support force value (the target support force value) for the support shock absorber, and bilaterally controls the damping of the electronic control valve in combination with the flowing direction signal detected by the liquid flow direction device. The support shock absorber has a simple structure, is simple in terms of the damping control method, and can achieve the automatic damping adjustment function of the shock absorber in order to realize damping self-adaption.
