[0002] Independent suspension is to suspend the wheels on each side under the frame through elastic suspension. The axle is disconnected. Within the elastic deformation range of the suspension, the wheels on both sides move independently, which can reduce the vibration of the frame and body during driving, help eliminate the yaw of the steering wheel, and improve driving stability and smoothness. However, compared with the ordinary bridge hub oil seal first installed in the hub, the independent suspension needs to be assembled using a hanger. After the assembly is completed, the hanger is used to seal the independent suspension bridge hub outer oil seal to the shaft head outer oil seal seat, and then assembled in the hub. The installation process is more complicated. In addition, during the independent suspension assembly process, the hanger needs to be used multiple times to adjust the independent suspension posture, and the assembly efficiency is low.
