The left hydraulic shock absorber 4 is located at the center of the left coil spring 7. The left hydraulic shock absorber 4 and the upper end of the left coil spring 7 are fixedly connected with a left top plate 5, which connects the hydraulic shock absorber and the upper end of the coil spring, and is connected to the vehicle body to transmit the shock and vibration after shock absorption to the vehicle body. The left end of the bracket 1 is movably connected with a left fixed plate 14, which is used as a connecting bridge between the wheel and the suspension system. The left surface of the left fixed plate 14 is fixedly connected with a left wheel 15, which is used to support the weight of the vehicle together with other wheels of the vehicle, and contact with the road surface during driving to transmit the driving force and braking force of the vehicle.

[0024] The upper surface of the bracket 1 is fixedly connected with a right bottom plate 9 by bolts 8, which is used as the installation basis for the right shock-absorbing assembly (including a hydraulic shock absorber and a coil spring). The right bottom plate 9 is located on the upper surface of the right support rod.
