Abstract

Hybrid drive containing a clutch between an engine power-output shaft (4) and a transmission power-input shaft (16) arranged axially with respect to the said power-output shaft; a first electric machine (6) connected to the engine power-output shaft (4) in a torque-transmitting manner; a second electric machine (14) connected to the transmission power-input shaft (16) in a torque-transmitting manner; preferably also a torsional vibration damper (8), which is connected in a rotationally fixed manner to the engine power-output shaft (4), the first-electric machine (6) being connected to the engine power-output shaft (4) in a torque-transmitting manner, ahead of the torsional vibration damper (8) in terms of the direction in which the torsional vibration damper (8) transmits the power of the propulsion drive engine. The parts of the hybrid drive are nested axially one inside the other.
