Torque transmission device for motor vehicles robotized gear box, has tightening discs radial at clutchs exterior to link two flywheels and to allow their rotation when actuator is in and starts from rest position, respectively

摘要

The device has primary and secondary flywheels connected in rotation by a vibration damper (20), and a clutch (E1) controlled by a hydraulic actuator (48) that is controlled by a hydraulic pressure. The actuator controls tightening discs (118, 120) radial at an exterior of clutch to link the flywheels when the actuator is in a rest position and to allow their rotation relative to start of the actuator from its rest position. The clutch (E1) connects the secondary flywheel to a shaft (38).
