摘　　要：履带式机械具有降低接地比压和防止下陷的优点,履带机械的转向普遍采用离合器和制动器,结构简单,但存在转向费力、不能实现原地转向的缺点。本研究采用的液压驱动设计方案,解决了转向灵活,能实现原地转向等问题,对工程应用有较大的参考价值。Tracked machinery has the advantages of reducing the ground pressure and avoiding sinking. Tracked machinery adopt clutch and brake which has the advantage of suppleness and has the disadvantage of difficult to be turned and can＇t turning at original point. In this study, the hydraulic-driven design programs to address the shift flexible, realization of in continuous rotational direction ect problems of engineering applications have a greater reference value.
