Abstract
Through the comparative analysis of different types of transport vehicles, the paper puts forward the concept of Track-Wheel transport vehicles and expounds the crawler travel mechanism of the wheel-shift interchange transport vehicles. It is concluded that the Track-Wheel transport vehicle has the advantage of operating in harsh environments such as mud and sand. The article designs the track mechanism and focuses on the strength checks of the important components of the track walking mechanism, namely the track, the load wheel and the load wheel axle. And it is concluded that under the maximum load, the track, the load wheel and the load wheel axle can meet the bearing requirements.
