为研究多离合器对液压机械无级变速器(Hydro-mechanical continuously variable transmission,HMCVT)传动效率的影响,针对变速器中包含多个湿式摩擦离合器构成闭式回路的结构特征,分析了离合器带排转矩对液压机械无级变速器效率特性的影响。通过对影响传动效率的离合器分离阶段所产生的带排转矩的分析与计算,建立了闭式回路中离合器分离阶段的动力传递计算模型,推导出闭式传动中离合器带排转矩造成的功率损失计算公式,进而推导出传动系总效率的计算方法,通过实例计算表明了HMCVT中的多个摩擦离合器的带排损失对其传动效率的影响较大。
In order to study the influence of multiple clutches on the transmission efficiency of a hydro-mechanical continuously variable transmission (HMCVT),the structure characteristics of a closed loop consisting of multiple wet friction clutches in the transmission are investigated. The influence of clutch drag torque on the efficiency characteristics of hydro-mechanical CVT is analyzed. By analysis and calculation of the drag torque generated in the clutch disengagement stage,which affects the transmission efficiency,a calculation model for power transmission in the clutch disengagement stage in a closed loop is established,a calculation formula for power loss caused by clutch drag torque in closed transmission is deduced and a calculation method for the total efficiency of the transmission system is further derived. The calculation results show that the band and row loss of multiple friction clutches in HMCVT has a great influence on its transmission efficiency.
