Abstract

An electric drive system for a motor vehicle includes a first electric machine with a first rotor, a second electric machine with a second rotor, and a reduced coupling gearing, which has a first planetary gear set, a second planetary gear set, a first input shaft, a second input shaft, a first output shaft, and a second output shaft. The first input shaft introduces first torques emanating from the first electric machine into the reduced coupling gearing. The second input shaft introduces second torques emanating from the second electric machine into the reduced coupling gearing. The first output shaft diverts third torques from the reduced coupling gearing. The second output shaft diverts fourth torques from the reduced coupling gearing.
