Abstract:
1. A drive device for a motor vehicle, comprising: at least one electric machine having at least one rotor element which includes a single-piece, essentially sleeve-shaped rotor carrier to delimit an installation area in a radial direction; at least one transmission device disposed, at least partly, in the installation area and configured to be driven by the electric machine via the rotor element, the transmission device including a transmission housing located radially inside of the rotor element and a differential gear having a differential case; two drive shafts rotatable by the rotor element through the transmission device and extending in an axial direction; and a plurality of roller bearings including two roller bearings spaced from each other in the axial direction and directly supporting the drive shafts in the transmission housing in absence of intermediate elements, two further roller bearings spaced from each other in the axial direction and directly supporting the rotor carrier on the transmission housing in absence of intermediate elements, and an additional roller bearing rotatably supporting one axial end of the differential case on the transmission housing.
