[0049] In the related art, the axial fixation of the balance elbow shaft is achieved by threaded connection and fixed clamps. However, the threaded connection requires a tightening torque, and the pre-tightened nut can prevent the balance elbow shaft from rotating or increase the rotating friction. In addition, the nut can only achieve axial positioning in a single direction, and the opposite direction is achieved by fixed clamps, which requires higher connection strength of the fixed clamps. Moreover, the connection mode in the related art increases the axial length of the balance elbow shaft, which requires more space for safety. The threaded connection is hidden inside the vehicle body. Once the threaded connection is loose, it can cause the track to deviate, aggravate the wear of the weight wheel, and other adverse effects.
[0050] Therefore, in one aspect of the embodiments of the present disclosure, a balance elbow connecting device is provided.
