Abstract

The invention relates to the technical field of shock absorbers, in particular to an active control serpentine shock absorber, a vibration damping system and a vehicle. When a piston of the active control serpentine shock absorber reciprocates in a hydraulic cylinder, the interior of the hydraulic cylinder is divided into two cylinder bodies, and the two cylinder bodies respectively communicate with an oil storage tank through two main oil paths to form a main loop between the hydraulic cylinder and the oil storage tank; and a reversing valve is arranged between the two main oil paths and theoil storage tank and used for changing the flow direction of the main loop when the shock absorber is in an active mode and adjusting the displacement of the piston in the hydraulic cylinder. When theshock absorber is switched to the active mode, the displacement of the piston is changed through the oil pressure difference between the two cylinder bodies in the hydraulic cylinder, so that the problem that the performance parameters of traditional serpentine shock absorbers cannot be adjusted and consequently a bogie is in a radial position relative to the vehicle body when the vehicle runs ina curve in the prior art is solved, the curve passing speed of the train is increased, the wheel rail abrasion is reduced, and the service life of the vehicle is prolonged.

Description

technical field

[0001] The invention relates to the technical field of shock absorbers, in particular to an actively controlled anti-serpentine shock absorber, a shock absorber system and a vehicle. Background technique

[0002] The anti-snake damper is an important part of the suspension system. Its main function is to generate a rotary damping force between the bogie frame and the car body, and consume the vibration energy between the two, thereby suppressing the snake-like vibration. .

[0003] The anti-snaking shock absorber is a key component that affects the stability of train operation. When the train is running in different states, the parameter requirements for the shock absorber are also different. According to the principle of vibration reduction, the traditional anti-serpentine shock absorber is a passive anti-snake shock absorber. The characteristic curve of the traditional passive shock absorber is fixed, and its performance parameters cannot be adjusted in r...
