Abstract

An electric drive unit has a first electric engine with a first rotor, a second electric engine which with a second rotor, and a gear unit having a differential, which has exactly three first shafts arranged coaxially to each other. The three first shafts are a sum shaft to which the first rotor is connected in such a way that torques supplied by the first rotor can be introduced into the gear unit via the sum shaft, a first differential shaft coupled to a first vehicle wheel in such a way that torques can be discharged from the gear unit via the first differential shaft and transmitted onto the first vehicle wheel, and a second differential shaft coupled to a second vehicle wheel in such a way that torques can be discharged from the gear unit via the second differential shaft and transmitted onto the second vehicle wheel.
