Abstract

A power train between the output shaft of the engine and the input shaft of the transmission in the power train of a motor vehicle has a composite flywheel receiving torque from the output shaft and transmits torque to the input shaft by way of a clutch disc in response to engagement of a friction clutch which is arranged to transmit torque between the clutch disc and the flywheel. The clutch disc has an input section adapted to receive torque from the flywheel and an output section adjacent the mass of a dynamic damper. Transmission of torque between the mass and the clutch disc takes place by way of the coil springs of an oscillation damper and a slip clutch in series with the oscillation damper.
