Drive unit for a vehicle

A drive unit for a vehicle, comprising:

• a first electrical machine;
• a second electrical machine arranged axially parallel to the first electrical machine;
• a manual gearbox with a plurality of gears, the manual gearbox arranged axially parallel to the first and second electrical machines;
• a differential with one differential input shaft, a first differential output shaft and a second differential output shaft;
• a drive shaft configured for connecting the first electrical machine to the manual gearbox;
• an output shaft configured for connecting the manual gearbox to the differential;
• a first positive-locking shift unit having a first shift element, a second shift element, and a first sliding sleeve which is displaceable by means of a first actuator into a respective one of three shift positions;
• and
• a first spur gear stage, a second spur gear stage, a third spur gear stage, and a fourth spur gear stage, wherein the first electrical machine is connected to the drive shaft via the first spur gear stage and the second spur gear stage, and wherein the second electrical machine is configured to be connected to the drive shaft or to the output shaft via the third spur gear stage and the fourth spur gear stage,
• wherein, in a first shift position of the first sliding sleeve, the first shift element is closed and the second electrical machine is connected to the drive shaft with an actuating effect;
• wherein, in a second shift position of the first sliding sleeve, both shift elements are open and the second electrical machine is decoupled from the manual gearbox;
• wherein in a third shift position of the first sliding sleeve the second shift element is closed and the second electrical machine is connected to the output shaft with an actuating effect;
• wherein the drive shaft is configured as a hollow shaft and the output shaft is arranged within the drive shaft.
