The multiple groups of limiting holes 10 are evenly distributed on the surface of the wheel hub 4. The buffer column 11 is installed at both ends of the limiting holes 10. The No. 1 buffer plate 12 is welded and installed on the top of the buffer column 11. Multiple groups of No. 1 dampers 13 are installed between the No. 1 buffer plate 12 and the wheel hub 4.
