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。
Based on the analysis of the change rule of the traction force of the loader, a hydrostatic-mechanical continuously variable transmission scheme suitable for the power transfer of the loader is proposed. For the low speed, high torque excavation and starting conditions, high speed, low load transition conditions and power output changes in the conditions of the transfer of materials, described the hydrostatic - mechanical continuously variable transmission system to meet the transmission needs Principle and control of hydrostatic-mechanical continuously variable transmission system.
