Drehmomentübertragungseinrichtung und seine Steuerung

摘要

A friction torque transmitting device (14) (e.g. with a fluid actuated piston (96)), and its control comprises shaft means (84) and means (89) for transmitting torque between the device (14) and a vehicle, directional flow control means (114) having two input ports (107,108) selectively connectable to the device (14) depending on the direction of torque transmission, each input port (107;108) having a shuttle valve (126,130) to selectively direct a controlled pressure lines (122,128,138) to its respective input port (107,108).
