Device for a vehicle driveline with an axle differential

A device for a vehicle drivetrain, comprising:

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