摘　　要：对大功率推土机的差速转向技术做了介绍,并对该机构的组成、工作原理及使用特点进行了讨论分析。This paper introduced a new type of differential steering gear equipped with heave-duty crawler dozer and analyzed its working principle as well as its special application by kinematics analysis. It is discovered that the revolving direction of hydraulic motor decided revolving direction of the dozer, and the revolving speed of hydraulic motor decided revolving radius of the dozer. Differential steering gear had more advantages of steering, smaller revolving radius and less maintenance. The results indicate that the differential steering gear had more advantages than steering clutches-brake steering.
