A wheel bearing assembly includes a wheel hub, at least one inner ring, an outer ring, and one or more rolling elements. An accommodation space may be formed inward of a vehicle-body-side end portion of the wheel hub to accommodate a constant velocity joint, and a plurality of recesses for accommodating rotating elements of the constant velocity joint are formed on an inner peripheral surface of the accommodation space to be spaced apart from each other along a circumferential direction. A first heat-treated hardened portion may be formed on the inner peripheral surface of the accommodation space, and may be formed to have portions with which the rotating elements of the constant velocity joint is brought into contact. A second heat-treated hardened portion may formed on an outer peripheral surface of the wheel hub. The first and second heat-treated hardened portions may not overlap each other.

Wheel bearing assembly

A wheel bearing assembly may include a wheel hub having a hub flange; one or more inner rings configured to be mounted to one side of the wheel hub; an outer ring provided radially outward of the one or more inner rings; a spacer coupled to a vehicle-body-side end portion of an inner ring disposed on a vehicle-body-side; and one or more rolling elements provided between the one or more inner rings and the outer ring. The one or more inner rings may be configured to be held on the wheel hub by plastically deforming a vehicle-body-side end portion of the wheel hub in a radially outward direction. A plurality of recesses for accommodating rotating elements of a constant velocity joint may be formed on an inner peripheral surface of the vehicle-body-side end portion of the wheel hub in a spaced-apart relationship with each other along a circumferential direction.
