Claims (10)

1 . Wheel hub drive unit for driving a vehicle wheel of a motor vehicle, comprising

a wheel hub drive that has a bearing element by which the wheel hub drive is arranged on a wheel hub of the motor vehicle,

the wheel hub drive has a mechanical blocking element for applying a braking force on the wheel hub.

2 . Wheel hub drive unit according to claim 1 , wherein for applying the braking force, the blocking element acts in at least one of a radial or an axial direction relative to a rotational axis of the wheel hub on a surface of the bearing element.

3 . Wheel hub drive unit according to claim 1 , wherein for applying the braking force, the blocking element acts in at least one of a radial or an axial direction relative to a rotational axis of the wheel hub on a surface of a brake drum provided on the wheel hub drive.

4 . Wheel hub drive unit according to claim 1 , wherein for applying the braking force, the blocking element acts in at least one of a radial or an axial direction relative to a rotational axis of the wheel hub on a surface of a flange journal provided on the wheel hub drive.
