摘　　要：分析装载机牵引力的变化规律,在此基础上提出一种适合于装载机动力传递要求的静液-机械无级变速传动方案。分别针对低转速、大转矩的铲掘和起步工况,高转速、低负荷的转场工况和动力输出变化的转运物料工况,阐述静液-机械无级变速传动系统满足传动需求的原理及静液-机械无级变速系统的控制方法。An analysis of stepless gear reduction. We put forth a concept of hydrostatic-mechanical gear reduction to suite the loader's power transmission as based on a variation law analysis of the loader's draw-bar force. And then, we individually described the very system and its controls, including of the low RPM and high torque excavation and its initial conditions, high-RPM and low load traveling conditions, and conditions in materials handling with power output variation, where how the gear reduction system satisfies the drive demand.
