Abstract

An electric axle drive for a motor vehicle includes a first electric engine, which has a first rotor, a second electric engine, which has a second rotor, and a differential transmission with three shafts. The first rotor can be coupled with the input shaft such that torques originating from the first rotor are introduced into the differential transmission via the input shaft. A first switch element is configured to couple the second rotor with the first output shaft such that torques originating from the second rotor are introduced into the first output shaft. A second switch element is configured to couple the second rotor with the second output shaft such that torques originating from the second rotor are introduced into the second output shaft.
