自动变速器中的滑摩离合器滑摩时发动机的动力同时通过液力传动和机械滑摩传动两条路线传递,它能够在大范围内提高传动效率。文中推导了汽车自动变速系统在滑摩过程中的功率平衡方程,并利用该方程计算了滑摩过程的控制油压,选择合理的滑摩控制区域能够显著提高自动变速传动系统的传动效率和缓冲、抗振性能。该控制区域应该从发动机的扭振状况、变矩器离合器的滑摩率和功率分配比、变矩器的输出特性以及自动变速系统的换挡规律多个方面进行考虑。
Sliding friction clutch in automatic transmission Sliding friction motor power at the same time through the hydraulic transmission and mechanical sliding friction transmission of two routes, it can improve the transmission efficiency in a wide range. In this paper, the power balance equation of automatic transmission system is deduced and the control hydraulic pressure is calculated by this equation. Choosing a reasonable control region can significantly improve the transmission efficiency and cushioning of automatic transmission system , Anti-vibration performance. The control region should be considered in many aspects, such as the torsional vibration condition of the engine, the slip ratio and power split ratio of the torque converter clutch, the output characteristics of the torque converter, and the shift schedule of the automatic transmission.
