摘　　要：通过分析变量泵与变量马达的效率及排量比与主参数的关系,建立 了静压推土机变量泵-变量马达传动系统效率与车速的计算方法,提出 了相应参数的控制范围。Through analyzing the relation of efficiency and displacement, rotation speed, pressure of variable pump, motor, and the relation of displacement ratio and velocity of crawler dozer, the authors set up the analytic methods on the efficiency of variable pump-variable motor transmission system and vehicle speed. At last, by comparing the results of sample machine in the theoretic and test, the control scope of displacement ratio, rotation speed, pressure and working velocity of hydrostatic transmission crawler bulldozer are put forward.
