为了保证干式双离合器在摩擦片磨损后仍能可靠传递扭矩,首先利用解析法对常分离式膜片弹簧载荷-变形特性进行理论分析,提出了基于压力控制的膜片弹簧磨损后压力保持方法,其次通过优化设计对膜片弹簧的结构参数进行了优化,并利用MSC.Patran/Marc软件对优化后常分离式离合器膜片弹簧工作过程进行了有限元接触仿真,最终得到了更符合实际工况的膜片弹簧载荷-变形特性曲线。结果表明:经过优化后的膜片弹簧,采用压力控制方法,摩擦片磨损后无需机械补偿,仍能保证扭矩的可靠传递。
In order to ensure that the dry double clutch can still transmit the torque reliably after the wear of the friction plate, a theoretical analysis of the load-deformation characteristics of the normally-disengaged diaphragm spring is made by analytical method first, and the pressure-holding method of the diaphragm spring wear- Secondly, the structural parameters of the diaphragm spring were optimized through the optimization design. The finite element contact simulation of the diaphragm spring was carried out by using MSC.Patran / Marc software. Finally, Diaphragm spring load - deformation curve. The results show that the optimized diaphragm spring adopts the pressure control method, the mechanical wear compensation is not required, and the reliable torque transmission can be guaranteed.
