Large Harvester Modified With Half Chain Rail Anti Slip and Non Sinking Vehicle

As a new type of walking mechanism, replaceable triangular track wheels combine the advantages of tires and track walking mechanisms, improving the vehicle's passing performance while maintaining the original vehicle's maneuverability. Due to its light weight and no special requirements for the vehicle chassis, the triangular track walking device can quickly achieve the exchange of tires and track wheels. Therefore, applying it to engineering repair equipment can enhance the vehicle's adaptability to harsh environments and expand the equipment's operating range. This article focuses on the development of a triangular track wheel walking device for a 50 type loader used in backbone engineering emergency repair equipment. On the basis of studying the technology form of replaceable triangular track wheels, combined with the practical application requirements of engineering repair equipment, this article first designs a scheme for the triangular track walking device applied to a certain 50 type loader, and determines the structural layout and component composition of the walking device. Secondly, the main parameters of key components such as the base frame, drive wheels, support wheel system, damping and tensioning device, and tracks of the triangular crawler walking device were selected. The overall structure of the base frame adopts a middle support type, which poses a load-bearing challenge for the track wheels;
