摘　　要：本文论述了定量泵-变量马达容积调速回路的转速、转矩和功率特性,并对负载为恒功率和恒转矩负载时的实际回路的转速特性作了理论推导,分析了回路泄漏引起的“损失转速”对回路实际转速的影响。This paper deals with the speed, torque and power characteristics of rotating speed regulation circuit of constant displacement pumpvariable displacement hydraulic motor system. Theoretical derivation of speed charecteristics of actual circuits under constant power or constant torque load conditions are performed and the effect of 'speed loss' caused by circuit leakage on actual rotating speed of the circuit is analyzed.
