多参数耦合下湿式换挡离合器滑摩特性

Slipping Friction Characteristics of Wet Shifting Clutch With Multi-Parameter Coupling

以某车辆的湿式换挡离合器为研究对象,分析多参数耦合下湿式换挡离合器的滑摩特性.基于多体动力学和Hertz接触理论,在ADAMS软件中建立和验证离合器动态分析模型,仿真研究接合油压、摩擦副主、从动件初始转速差、摩擦因数,以及摩擦片刚度等因素对湿式换挡离合器滑摩特性的影响规律.结果表明:适当提高接合油压,增大摩擦因数、摩擦片刚度和摩擦副主、从动件初始转速差,可以有效改善湿式换挡离合器滑摩特性.

Taking a vehicle′s wet shifting clutch as a research object,the slip characteristics of the wet shifting clutch under multi-parameter coupling were analysed.Based on multi-body dynamics and Hertz contact theory,a dynamic analysis model of the clutch was established and verified in ADAMS software.The influence oil pressure,friction sub-master,speed difference of follower,friction factor,and friction plate stiffness on the slip characteristics of wet shift clutch was studied through simulation.The results show that:properly improving the hydraulic pressure,increasing the friction factor,stiffness of friction plates and deputy chief of friction and initial rotation difference of follower can effectively improve the slip characteristics of the wet shift clutch.
