Claim:
1. An axle drive system for a motor vehicle, comprising: a dynamoelectric drive motor having a first rotor shaft; a shiftable superimposing transmission having a first and a second gear stage; a shift actuator system having an axially movable shifting sleeve for shifting the two gear stages, the superimposing transmission having a transmission input shaft non-rotatably connected to the first rotor shaft of the drive motor and operatively connectable via the shifting sleeve to the second gear stage through the first gear stage, and a power divider having a first power divider shaft driving a first output shaft and a second power divider shaft driving a second output shaft, the first and second power divider shafts, the first and second output shafts, and the first rotor shaft being rotatably arranged about a common axis of rotation oriented transverse to a direction of travel of the motor vehicle, the shift actuator system including an electric motor for moving the shifting sleeve and disposed in a space bounded in the axial direction by the first gear stage on a first side and the second gear stage on a second side of the drive system; wherein the power divider is configured as a planetary differential, the first power divider shaft is a planet carrier of the power divider, the second power divider shaft is non-rotatably connected to a sun gear of the planetary differential.
