For the drive train of a motor vehicle, a drive train assembly can be used which comprises two operational components which are separate from one another, each of which comprises a motor and a transmission which faces the drive wheel to be driven. The transmission, which can be a spur gear transmission with a driven shaft part oriented eccentrically with respect to the axis of rotation of the motor device, or can be a planetary transmission, is located together with the motor device on a common support part, on which the driven shaft of the motor device and the driven shaft part of the transmission are also mounted. The transmission is coupled to the drive wheel by means of a universal joint propeller shaft. To install the transmission-side joints of the universal joint propeller shafts, even with short universal joint propeller shafts, in the vicinity of the instantaneous center of rotation of the drive wheel, the two components are connected to one another by means of an auxiliary frame and with the bolster of the drive axle system. Merely by adapting the auxiliary frame, which may also be a component of the bolster, the drive train can be adapted to meet the special requirements of the motor vehicle, without having to make extensive modifications to the design of the components. The component can thus be constructed using standardized transmission and motor components.
