Abstract
A drive unit has first and second electrical machines arranged axially parallel, a manual gearbox arranged axially parallel to the electrical machines, a differential, a drive shaft, an output shaft, and a positive-locking shift unit having a first shift element, a second shift element, and a sliding sleeve displaceable via a first actuator into one of three shift positions. In a first shift position, the first shift element is closed and the second electrical machine is connected to the drive shaft with an actuating effect; in a second shift position, both shift elements are open and the second electrical machine is decoupled from the gearbox; in a third shift position, the second shift element is closed and the second electrical machine is connected to the output shaft with an actuating effect. The drive shaft is hollow, and the output shaft is arranged within the drive shaft.
