Patent ID: 8485929

Claim:
A motor vehicle power train comprising: a main drive engine, comprising an output shaft for driving the drive wheels of the motor vehicle; an electric motor, comprising a rotor and a stator, also for driving the drive wheels of the motor vehicle; an automatic transmission, automatic gearbox or manual gearbox, comprising a plurality of selectively settable drive connections for the implementation of gears, and a transmission input shaft and a transmission output shaft in order to selectively set a plurality of gear ratios between the transmission input shaft and the transmission output shaft, with the rotor of the electric motor being disposed in a drive connection between the output shaft of the main drive engine and the transmission input shaft, and can be decoupled from the output shaft of the main drive engine by means of a first clutch; at least one ancillary unit which can be driven by the main drive engine; the rotor of the electric motor comprises an exterior drive having a gearing or friction surface which has a driving connection to the at least one ancillary unit in order to drive the at least one ancillary unit by means of the rotor, characterized in that the transmission comprises a transmission housing, with the transmission input shaft being arranged on a first face side of the transmission housing and the transmission output shaft being arranged on a second face side of the transmission housing which is arranged opposite of the first face side, and an auxiliary output module is connected on the first face side to the transmission housing, comprising a housing which encloses the electric motor, the first clutch and an auxiliary output shaft which protrudes from the housing of the auxiliary output module, with the auxiliary output shaft being in a drive connection with the rotor and bearing a pinion which meshes with an external gearing of the rotor either indirectly or via an interposed gearwheel and drives the ancillary unit or a rotor of the ancillary unit, and carries the ancillary unit.
