A drive train is disclosed that includes an engine operable in a first engine operating state and a second engine operating state and a torsional-vibration damping system operatively connected to the engine. The torsional-vibration damping system includes a first torsional-vibration damper having a primary inertial mass and a secondary inertial mass, a second torsional-vibration damper, a first centrifugal pendulum arranged on the secondary inertial mass of the first torsional-vibration damper, and a second centrifugal pendulum arranged on the second torsional-vibration damper.

Torsional-vibration damping system for a vehicle drive train

An automatic friction clutch in a drive train of a motor vehicle is controlled to transfer a clutch torque that includes an engine torque-dependent component and a clutch slip-dependent component.

Method and system for control of an automatic friction clutch arranged between an engine and a gearbox on a motor vehicle

An automatic friction clutch, contained in the drive train of a motor vehicle is controlled such that a preset clutch torque can be transmitted. The preset clutch torque is composed of a pilot clutch torque M and a clutch torque Msr, which is dependent on slip.

Apparatus for transmitting torque between the output shaft of the engine and the input shaft of the transmission in a motor vehicle has a fluid coupling with a housing secured to the output shaft and containing an impeller, a runner and, if necessary, a guide wheel. The runner is connected to a hub on the input shaft by a carrier for a torsionally elastic damper having coil springs which receive torque from the housing. The damper is in series with a clutch which can be operated to bypass the fluid coupling.

Power transfer apparatus with fluid coupling

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.
