Claim 0:
1. A drive apparatus for a two-track vehicle, having an electric machine operating as a motor to drive vehicle wheels via an axle differential, comprising:
output shafts respectively coupled to the vehicle wheels, one of the output shafts being divided into first and second shaft sections, the first shaft section having spline teeth; and
a positively locking clutch, configured to couple the first and second shaft sections in a driving mode of the electric machine to drive the vehicle wheels, and to decouple the first and second shaft sections when the electric machine is deactivated, thereby reducing drag losses, the positively locking clutch including
a sliding sleeve arranged on the spline teeth of the first shaft section nonrotatably, but displaceable axially, in response to an actuating force, between an open coupling state of the sliding sleeve not in positively locking connection with the second shaft section, and a closed clutch state of the sliding sleeve in the positively locking connection with the second shaft section,
an actuator configured to generate the actuating force in response to a closing signal, and
a coordinator, communicatively connected to the actuator and in electric signal connection with the electric machine, configured to send the closing signal to the actuator when a clutch engagement requirement exists, thereby activating the actuator to close the positively locking clutch, and, when the clutch engagement requirement does not exist, to send an opening signal to the actuator to open the positively locking clutch, and to activate the electric machine before either of a coupling operation and a decoupling operation, whereby during each of the coupling operation and the decoupling operation a substantially load-free actuation of the positively locking clutch is possible.
