Abstract

The invention provides a crawler wheel walking device capable of realizing wheel-crawler conversion. The crawler wheel walking device comprises a wheel-type drive system, a rotary high-pressure oil supply mechanism, a crawler belt drive system, a wheel-type power transmission system, a plurality of deformation adjusting mechanisms and a deformable crawler belt. The deformable crawler belt is positioned at the outermost layer of a walking device body and adopts flexible materials. The deformation adjusting mechanisms are uniformly arranged in the deformable crawler belt to control the walking device body to switch between a tire state and a crawler belt state. The rotary high-pressure oil supply mechanism provides deformation power for the deformation adjusting mechanisms, the crawler beltdrive system is located in the deformable crawler belt and is connected with teeth of the deformable crawler belt, and the wheel-type drive system is located at the axial center of the walking devicebody and is connected with the wheel-type power transmission system. The problem of poor adaptability of a traditional walking device to road conditions is solved. The designed crawler wheel walking device can switch the driving state according to different ground conditions, and thus the adaptability and trafficability of a vehicle to different ground conditions are improved.

Description

technical field [0001] The invention relates to the technical field of vehicle driving systems, in particular to a crawler wheel traveling device capable of realizing wheel-shoe conversion. Background technique [0002] Different walking devices have different adaptability and passability to various complex and changing road conditions. Complex terrain conditions and unpredictable working environments place higher requirements on the flexibility of the vehicle walking unit. The traditional wheel structure is divided into: wheel structure and crawler structure. The wheel structure has the advantages of fast moving speed, simple structure, convenient control, and flexible movement. However, this structure is highly dependent on the ground and is not suitable for overcoming obstacles. The contact area and obstacle-crossing performance are very good, and it is suitable for all kinds of complex terrains. The disadvantage is that it is slow, bulky, inflexible in movement, and con...
