Triangular crawler walking system with suspended shock-absorbing device

Abstract

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.

Description

technical field [0001] The invention relates to a crawler walking system, in particular to a triangular crawler walking system with an all-terrain belt suspension shock absorber that can replace tires of a four-wheel drive skid steer loader. Background technique [0002] The skid steer loader is a multifunctional construction machine that can adapt to such working conditions. At present, the walking system of the skid steer loader is divided into two types: tire type and crawler type. These two types of walking systems have their own advantages and disadvantages, and the differences are relatively large and cannot be replaced with each other. [0003] Chinese patent CN102069856A discloses a replaceable crawler wheel for a loader. The crawler wheel adopts an intermediate supporting base frame structure, and the drive wheel, supporting wheel set, guide wheel set and tensioning wheel set are connected through the base frame. Among them, the supporting wheel set adopts a three-...

AI Technical Summary

Problems solved by technology

However, for smaller skid loaders, the relevant components cannot be arranged according to the above scheme, especially the arrangement of the three-axis swinging support wheel is even more difficult.

If the structure is scaled down, the obstacle surmounting performance of the support wheel will be reduced, and the effect of slowing down the impact load of the road on the track wheel will also be greatly reduced
