Abstract
An electric axle drive () for a motor vehicle has an electric machine () for driving at least one output shaft () of the axle () of the motor vehicle and has a spur gear unit () with two spur gear stages (). The electric machine () can drive the spur gear stages (), which, in turn, can drive a planetary gear unit (). The planetary gear unit () can be shifted between two gears. In the first gear, a transmission ratio is shifted in the planetary gear unit (), and, in the second gear, the planetary gear unit () is shifted as a block.
