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.
