液压机械无级变速器换段品质影响因素试验

Experiment of Shift Quality Factors for Hydro-mechanical CVT

以提高拖拉机液压机械无级变速器换段品质为主要目的,运用正交试验方法进行了台架试验,并对换段品质各影响因素参数进行了合理匹配;确定了影响液压机械无级变速器换段品质的各影响因素之间的主次关系,并进行了拖拉机犁耕满负荷工况下的试验验证。研究方法及结论对提高液压机械无级变速器的换段品质具有一定的理论指导意义和实用价值。

With the aim of improving the gearbox shift quality of tractor hydro-mechanical continuously variable transmission （CVT）, the effects of factors on shift quality were investigated by bench test. Then, the orders of the above factors were obtained. The working test of tractor with full load was carried out. The research had theoretical significance and practical value in transmission shift quality and control methods of hydro-machinery CVT.
