Claim 9:
10. A wheel hub drive for a vehicle, the wheel hub drive comprising:
a drive housing;
a hub output for coupling to a driven wheel, the hub output being mounted rotatably relative to the drive housing;
a wheel brake configured to brake the hub output relative to the drive housing, the wheel brake having a stationary brake partner and a rotating brake partner, the stationary brake partner being connected to the drive housing, and the rotating brake partner being connected to the hub output in at least one of a geared manner or for conjoint rotation therewith, the stationary and rotating brake partners being movable relative to one another when the wheel brake is actuated, and being frictionally connected to one another in a braking state,
a parking brake configured to fix the hub output relative to the drive housing, the stationary and rotating brake partners being movable relative to one another when the parking brake is actuated and being frictionally connected to one another in a parked state;
the parking brake has a ramp mechanism with a rotatable ramp section configured to move linearly in an axial direction upon a rotational movement thereof to transfer a parking force to at least one of the stationary or rotating brake partner, the ramp mechanism comprising a stationary and a rotatable ramp section; and
the parking brake further has a fixing section for fixing the stationary ramp section on the drive housing, the fixing section being mounted on the drive housing, and the stationary ramp section and the fixing section each being in engagement with one another via a straight toothing.
