Research on the driving torque transition of a crawler vehicle affected by some objects

Abstract

Some objects, like gravels, sands or stones, comes into the crawler during these types of vehicle moves on rough terrain. These objects can be a key factor to hamper their locomotion. However, the causal relationship has been unclear. Therefore, the relationship between the sprocket rotation torque and the tension applied to the crawler has been investigated in this research. Experimental setup that can be changed the tension between two axes connected by crawler, and be measured both the sprocket torque, and belt tension was established to be shown the results of the transition of a tension of the crawler and a torque when foreign substance was caught into the sprocket.
