Claim 0:
1. 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 for conjoint rotation therewith, 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; and
the parking brake has a ramp mechanism, the ramp mechanism being configured to convert a rotary movement into a linear movement in order 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, one of the stationary and the rotatable ramp sections has a helical toothing on an inner circumference thereof and the other of the stationary and the rotatable ramp sections has a helical toothing on an outer circumference thereof, the ramp sections being in engagement with one another to form the ramp mechanism via the helical toothings.
