Abstract

An electric drive unit includes a first electric engine having a first rotor, a second electric engine having a second rotor, and a transmission unit having a differential transmission with exactly three first shafts arranged coaxially with one another. The three first shafts are a sum shaft to which the first rotor is connected such that torques provided by the first rotor can be introduced into the transmission unit via the sum shaft, a first differential shaft coupled to a first vehicle wheel such that torques can be discharged from the transmission unit and transmitted to the first vehicle wheel via the first differential shaft, and a second differential shaft coupled to a second vehicle wheel such that torques can be discharged from the transmission unit and transmitted to the second vehicle wheel via the second differential shaft.
