Abstract

A hybrid-electric powertrain includes an internal combustion engine, a transmission, and an electric machine, where the electric machine is connected to the transmission for transmitting torque. The transmission has a transmission housing, within which there is disposed an output-side gear set assembly, and also a transmission housing cover disposed on an output side of the transmission as seen in an axial direction. The electric machine has a stator, a rotor, a rotor shaft connected to the rotor for conjoint rotation, and an electric machine housing. In addition, the electric machine has a connection housing for connecting the electric machine to the transmission housing. The rotor shaft of the electric machine is disposed parallel to a transmission input shaft of the transmission.
