  • Hybrid drive train
    Patent number: 9045034
    Abstract: A drive train for a motor vehicle has an internal combustion engine and a hydraulically shiftable transmission unit. The input of the transmission can be connected via a clutch arrangement to a crankshaft of the internal combustion engine. The output of the transmission can be connected to driven wheels of the motor vehicle. The crankshaft is connected to a pump shaft which drives a pump arrangement for a hydraulic arrangement, by means of which the transmission unit is shifted and/or lubricated. The pump shaft is connected to an electric machine. The pump shaft is connected to the crankshaft via a constrained motion mechanism. The electric machine is arranged in the axial direction between the constrained motion mechanism and a pump of the pump arrangement.
