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.

Drive unit for a vehicle

A device for a vehicle drivetrain has an axle differential, a differential blocking device for blocking and releasing the equalization function of the axle differential, a parking lock for blocking and releasing the drive output of the vehicle drivetrain, and an actuation mechanism configured to be driven by a drive unit. By way of the actuation mechanism, the differential blocking device and the parking lock can be actuated by the drive unit. Actuating the parking lock and the differential blocking device are correlated with one another in such manner that at the end of a first phase of actuation, only the equalization function of the axle differential can be blocked and the parking lock is in its disengaged condition. At the end of a second phase of actuation, the equalization function of the axle differential can be blocked, and the parking lock can be engaged.
