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).
