| 摘 要： | 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。

| Abstract: | When sliding in the sliding-friction clutch of the automatic transmission,engine power is transferred through both hydraulic transmission and mechanic sliding transmission,which can improve transmission efficiency in a large range.The power balance equation of automatic transmission during sliding is derived.The control oil pressure during sliding are calculated with the equation.It can apparently improve transmission efficiency,cushion characteristic and vibration resistance of automatic transmission to select rational sliding control area.Engine torsional vibration conditions,sliding rate of sliding clutch of automatic transmission,power distributing ratio,output characteristic and shifting rule of the automatic transmission,etc.,shall be considered when the control area is to be selected. |
