Abstract: A hybrid drive train of a motor vehicle with a transmission (1), a transmission oil sump (2) that is associated with the transmission (1), at least one electric machine, and a power electronics unit that is associated with the electric machine. A structural space (3) is provided for the power electronics unit, which is located under the transmission oil sump (2) of the transmission (1 ).

Abstract: The proposed electric machine with integrated power electronics is modularly constructed, it being possibly prefabricated and separately to install the parts stator carrier (2), control (10) for the power semiconductor DC+ (4), DC bars (5), power semiconductor (8), cooling duct (12) for power electronics and electric machine, stator (1) and stator winding (3).

Abstract: A transmission device (3) for a vehicle with an electric machine (26) that is arranged in a housing (11) is described. The electric machine (26) can be placed in active connection with a rotating component (13, 28) that can be guided in the power flow of the transmission device such that a level of torque that can be generated by the electric machine (26) can be transmitted to the component (13, 28). At least one electric component (45; 45Y) that comprises power electronics for the electric machine (26) is arranged in a cross-sectional area inside the housing (11) that is perpendicular to the longitudinal axis of the electric machine (26) and is located directly adjacent to the electric machine (26).
