Abstract

An electric drive device for a vehicle axle includes first and second electric engines having first and second rotors, respectively. A transmission has a first and second input shafts arranged coaxially with the first and second rotors, respectively, and an output shaft arranged in parallel with the first and second input shafts. An axle drive has a differential gear permanently meshing with at least one drive gearwheel connected to the at least one output shaft in a manner fixed against rotation. A first switchable spur gear pairing and a second spur gear pairing respectively couple the first and second input shafts with the differential gear in a torque-transmitting manner. When viewed in an axial direction along the at least one output shaft, the first electric engine, the first spur gear pairing, the at least one drive gearwheel, the second spur gear pairing, and the second electric engine are arranged one after the other in the specified order.
