Patent ID: 8777806

Claim:
A drivetrain for a parallel hybrid vehicle, comprising: an internal combustion engine having an output shaft, an electric machine having a shaft, a transmission having an input shaft connected in a rotationally conjoint manner to the shaft of the electric machine and the transmission having an output shaft for driving at least one axle of the hybrid vehicle, and a clutch between the internal combustion engine and electric machine, the clutch having a first element that is closable for achieving a positive locking connection of the electric machine to the internal combustion engine so that both the electric machine and the internal combustion engine drive the input shaft of the transmission, and the clutch having a second element that is closable for achieving a frictional locking connection of the electric machine to the internal combustion engine with a sufficient torque transmission to enable the electric machine to start the internal combustion engine, and the first and second elements being openable to decouple the internal combustion engine from the input shaft of the transmission.
