Beschreibung
Zusammenfassung:	An electric axle drive has a transmission arrangement with two gears, with an electric machine for driving two output shafts of the axle of the motor vehicle, a first spur gear stage which can be driven by the electric machine for driving an intermediate shaft and a planetary carrier of a planetary gear mechanism, which planetary carrier is connected fixedly to the intermediate shaft and receives planetary gears, and with an internal gear of the planetary gear mechanism for driving a second spur gear stage, a sun gear of the planetary gear mechanism and shifting elements for shifting the two gears. A first shifting element is configured as a clutch, by way of which the internal gear and the sun gear or the internal gear and the planetary carrier or the sun gear and the planetary carrier can be connected in a torque-transmitting manner.
