Abstract

Torque transmission unit includes an input shaft and an output shaft with a torsion damping device functionally arranged between the input shaft and an output shaft. A shift clutch is also operatively arranged between the input shaft and the output shaft for selectively varying the torque transmitted from the input shaft to the output shaft. The torsion damping device has at least a primary mass and a secondary mass, the primary mass being effectively connected to the input shaft and the secondary mass being effectively connected to the output shaft. The torque transmission unit further comprises an electric machine with a stator and a rotor effectively connected to the input shaft. At least one of the shift clutch and the torsion damping device is arranged within an annular space delimited by the rotor and the stator of the electric machine.
