Abstract
A wheel hub drive for a vehicle, having: a drive housing; a hub output mounted rotatably relative to the drive housing; a wheel brake for the hub output that has a stationary and a rotating braking partner, the stationary braking partner being connected to the drive housing for conjoint rotation therewith, and the rotating braking partner being connected to the hub output. The two braking partners are frictionally connected in a braking state, A parking brake for fixing 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 has a ramp mechanism for converting a rotary movement into a linear movement in order to transfer a parking force to the stationary and/or rotating brake partner.
