Torque converter having variable pitch stator and bypass clutch

A transmission includes a torque converter with both a variable pitch stator and a bypass clutch. These are controlled in two modes to maintain a target slip speed. In a first mode, the bypass clutch is fully released and slip is controlled by varying the pitch of the stator blades. In a second mode...

Zusammenfassung:A transmission includes a torque converter with both a variable pitch stator and a bypass clutch. These are controlled in two modes to maintain a target slip speed. In a first mode, the bypass clutch is fully released and slip is controlled by varying the pitch of the stator blades. In a second mode, the stator is held in the tightest position and slip is controlled by varying the torque capacity of the bypass clutch. The target slip is calculates based on a variety of different input signals depending on what type of vehicle maneuver is being performed. 本发明涉及种具有可变节距导轮和旁通离合器的变矩器。传动装置包括具有可变节距导轮和旁通离合器的变矩器。这些部件以两种模式被控制以保持目标打滑速度。在第模式中,旁通离合器完全释放,并且通过改变导轮叶片的节距来控制打滑。在第二模式中,导轮保持在最紧缩的位置,并且通过改变旁通离合器的扭矩容量来控制打滑。取决于正在执行什么类型的车辆操作,基于各种不同的输入信号来计算目标打滑。
