为了满足ZL30和ZL20装载机需要,对D310双涡轮液力变矩器的泵轮和导轮的出口角做了一系列的改变试验,选择了相应的出口角度,达到降低能容,提高输出性能的目的。双涡轮滚力变矩器有一个轴流涡轮和一个向心涡轮。原始设计者为了提高变矩系数及传递能量的效率,把轴流涡轮的工作特性用在起动工况和低速工况。而在高速工况时只允许向
In order to meet the needs of ZL30 and ZL20 loaders, a series of change experiments were made on the exit angles of the impeller and guide wheel of the D310 twin-turbo torque converter. The corresponding exit angle was selected to reduce the capacity and improve the output performance the goal of. Twin-turbine torque converter has an axial turbine and a radial turbine. In order to improve the torque conversion coefficient and the energy transfer efficiency, the original designers used the operating characteristics of axial-flow turbines in starting conditions and low-speed operating conditions. In the high-speed conditions only allowed to
