  • Patent number: 9776498
    Abstract: An assembly includes a transmission and an electric machine for a hybrid drive of a motor vehicle, and the transmission is a multi-stage standard transmission with first and second subtransmissions, each of which has a separate input shaft and shares an output shaft. Both input shafts are coupled to the shared output shaft via form locking shift elements of the subtransmissions. The assembly includes a first shiftable clutch which is allocated to a first input shaft such that the internal combustion engine is coupled to the first input shaft via the first shiftable clutch, and a second shiftable clutch which is allocated to the second input shaft such that the electric machine is coupled to the second input shaft via the second shiftable clutch. The electric machine is coupled to the internal combustion engine via a third shiftable clutch, and to the first input shaft via a fourth shiftable clutch.
