摘要
把装载机工作泵分为空载工作、满载工作、半载工作3种情况,分别计算ZL50装载机的输入特性和输出特性;完成ZL50装载机的牵引特性的计算。在此基础上,提出根据装载机油门开度、车速和油泵的压力为控制参数的3参数换挡规律。建立装载机传动系统数学模型,进行了计算机仿真。从仿真结果看,3参数换挡规律符合工程车辆的实际工作状态,能更好地满足工程车辆的动力性要求。
Input and output characteristics of ZL50 loader were measured under three working conditions of no load,full load,and half load.In every case,the matching calculation of engine and torque-converter was carried out.Then the traction force calculation of ZL50 loader was finished.The shift schedule of three variable parameters coming from the throttle position,the speed and the pressure of oil pump was introduced and the shift rule of ZL50 loader was designed. The dynamic simulating model of loader power trans...
