Abstract

The invention belongs to the technical field of vehicle suspensions, and discloses a vehicle side-turn-prevention suspension device. The vehicle side-turn-prevention suspension device comprises a suspension oil cylinder, a cross arm, a damping valve group, a low-voltage energy accumulator and a high-voltage energy accumulator, wherein the suspension oil cylinder is used for supporting the weight of a vehicle body, the upper portion of the suspension oil cylinder is hinged to the vehicle body, a lower portion piston rod is hinged to the middle of the cross arm, one end of the cross arm is connected with a wheel, and the other end of the cross arm is hinged to the vehicle body; the damping valve group is used for attenuating the vibration of the vehicle body, one end of the damping valve group is communicated with an upper cavity of the suspension oil cylinder and the high-voltage energy accumulator through oil pipes, the other end of the damping valve group is communicated with the low-voltage energy accumulator through an oil pipe, the damping valve group has resistance on oil liquid passing in the damping valve group, and the vibration energy carried by the oil liquid is dissipated in a temperature rise mode. By controlling the rigidity and damping of the suspension device, side turning in the steering process of a vehicle is restrained, and therefore the driving safety of the vehicle is improved. The vehicle side-turn-prevention suspension device plays an important role especially for large buses, heavy trucks and concrete mixers with a high gravity center on the aspect of preventing side turning of vehicles.

Description

technical field [0001] The invention belongs to the technical field of vehicle suspension, and relates to an anti-rollover suspension device for a vehicle. Through the improvement of the suspension structure and a damping valve group, the vehicle anti-rollover function can be realized. Background technique [0002] Vehicle rollover will cause traffic accidents. With the increase of the number of vehicles, vehicle rollover has become a serious vehicle safety problem, and at the same time it has brought great adverse effects and huge economic losses to the society. [0003] The reason for rollover is: when turning, due to the centrifugal force, the left and right loads are transferred, and at the same time, the left and right suspensions are greatly deformed under the action of the rollover moment generated by the centrifugal force, causing the car body to tilt and turn to the outside. From the analysis of the mechanism of the rollover, the root cause of the rollover is the tr...
