YJSW315型双涡轮液力变矩器是轮胎式装载机的核心部件,由泵轮、一级和二级涡轮、导轮等组成,以液力传动油为工作介质,其功能主要是自动无级变矩和变速、自动离合,并具有减缓冲击和过载保护作用,以使装载机及其发动机运转平稳。近几年随着液力变矩器四元件(导轮、一级和二级涡轮、泵轮)冲压焊接技术、叶轮精密铸造技术,以及精密加工机床、信息化性能试验台的应用,液力变矩器的质量得到很大提高,但是也发现YJSW315型双涡轮液力变矩器存在5
YJSW315 twin-turbo torque converter is the core component of the wheel loader. It consists of pump impeller, primary and secondary turbine, guide wheel and so on. The hydraulic transmission oil is used as working medium. Its function is mainly automatic and stepless Torque and speed change, automatic clutch, and has the impact of mitigation and overload protection, in order to make the loader and its engine running smoothly. In recent years, with the torque converter four components (guide wheel, the first and second turbine, pump wheel) stamping welding technology, precision casting impeller technology, and precision machining machine tools, information technology test bench applications, hydraulic Torque converter quality has been greatly improved, but also found YJSW315 twin-turbo torque converter exists 5
