A drive device for driving wheels of a motor vehicle includes a housing, an electric machine with a stator and rotor, a first output shaft for driving a first wheel, and a second output shaft for driving a second wheel. Via a differential transmission, first and second planetary gearsets are drivable by the rotor. First and second differential shafts transfer drive power from the differential transmission to the first and second planetary gearsets. The first differential shaft is mounted rotatably on an input shaft via bearings and the rotor is connected non-rotationally to the input shaft. A stable and non-buckling bearing of the second differential shaft in relation to the rotor is carried out via further bearings arranged on the second differential shaft or in the first differential shaft. The further bearings are arranged spaced apart from one another at least at a distance of twice an average bearing diameter.
