Improved vehicle suspension mechanism

The utility model discloses an improved vehicle suspension mechanism. The improved vehicle suspension mechanism comprises a hub base and a suspension base. The upper end and the lower end of the hub base are connected with the upper end and the lower end of the suspension base through an upper connecting rod and a lower connecting rod respectively. The suspension base is fixed to a vehicle body chassis. A shock absorber connected with the upper end of the suspension base is arranged in the middle of the lower connecting rod. A compensator is arranged between the upper end of the hub base and the lower end of the suspension base. The shock absorber comprises a piston assembly A and a compression medium assembly, a support A and a support B are elastically connected through the compression medium assembly, and a piston cavity A of the piston assembly A is filled with damping oil. The compensator comprises a piston assembly B, and a piston cavity B of the piston assembly is filled with damping oil. The bottom of the piston cavity B and the bottom of the piston cavity A are connected through a flow limiting valve. The flowing rate of the damping oil can be adjusted through an adjusting valve. By means of the improved vehicle suspension mechanism, the environment tolerance of the suspension structure can be effectively improved.
