Abstract
A vehicle drive unit has a first and second electrical machines arranged in parallel, a manual gearbox arranged parallel to the electrical machines, a differential, a hollow drive shaft for connecting the first electrical machine to the gearbox, an output shaft within the drive shaft and for connecting the gearbox to the differential. A positive-locking shift unit has first and second shift elements and a sliding sleeve that is displaceable into 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.
