Triangular crawler walking system with suspended shock-absorbing device

The invention relates to a triangular crawler walking system with a suspended shock-absorbing device. The triangular crawler walking system comprises a driving wheel, a tensioning wheel, a guide wheel, supporting wheels, a crawler and a support. The tensioning wheel and the guide wheel are respectively arranged at the two ends of the support. The driving wheel is arranged above the support. The supporting wheels are arranged between the tensioning wheel and the guide wheel and are connected with the support. The crawler surrounds the driving wheel, the tensioning wheel, the supporting wheels and the guide wheel to form a triangular structure. The supporting wheels are connected with the supporting through the suspended shock-absorbing device. The tensioning wheel is connected with the support through a V-shaped swinging rack. An adjusting rod which can adjust the tightness of the crawler is arranged between the swinging rack and the support. The support, the swinging rack and the adjusting rod form a linkage mechanism which can enable the tensioning wheel to swing. The triangular crawler walking system with the suspended shock-absorbing device has the beneficial effects that: 1) the rapid switching between a tire type and a crawler type of a skid loader can realized; and 2) by adopting the suspended shock-absorbing device, the obstacle detouring capacity of the entire loader is improved, the shock absorbing effect is guaranteed and the service life of the crawler walking system is improved.
