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.
