According to one embodiment of the present invention, a vehicle wheel bearing is provided that supports a wheel of a vehicle by rotatably mounting the wheel of a vehicle on a vehicle body. According to one embodiment of the present invention, a vehicle wheel bearing may include: a wheel hub having a wheel mounting flange; an inner ring mounted on the outer circumferential surface of the wheel hub; an outer ring having a vehicle body-side mounting flange; and a plurality of rolling elements that support the wheel hub and the inner ring so as to be able to rotate relative to the outer ring. According to one embodiment of the present invention, an axial spline part may be provided on the inner circumferential surface of the inner ring so that the axial spline part may be configured to be coupled to a spline engaging part provided on the outer circumferential surface of the wheel hub, and a cross-sectional tooth part may be provided on an inner axial cross section of the inner ring so as to be tooth-engaged with a cross-sectional tooth part provided on the outer axial cross section of a constant velocity joint. According to one embodiment of the present invention, the number of spline teeth of the axial spline part provided on the inner circumferential surface of the inner ring may be formed to be greater than the number of teeth of the cross-sectional tooth part provided on the inner axial cross section of the inner ring.

    본 발명의 일 실시예에 따르면, 차량의 휠을 차체에 회전 가능하게 장착하여 지지하는 차량용 휠베어링이 제공된다. 본 발명의 일 실시예에 따른 차량용 휠베어링은, 휠장착 플랜지를 구비하는 휠허브와; 휠허브의 외주면에 장착되는 내륜과; 차체측 장착 플랜지를 구비하는 외륜과; 휠허브 및 내륜을 외륜에 대해 상대회전 가능하게 지지하는 복수의 전동체를 포함하도록 구성될 수 있다. 본 발명의 일 실시예에 따르면, 내륜의 내주면에는 축방향 스플라인부가 구비되어 축방향 스플라인부가 휠허브의 외주면에 구비된 스플라인 결합부에 결합되도록 구성될 수 있고, 내륜의 내측 축방향 단면에는 단면 치형부가 구비되어 등속조인트의 외측 축방향 단면에 구비된 단면 치형부와 치형 결합되도록 구성될 수 있다. 본 발명의 일 실시예에 따르면, 내륜의 내주면에 구비된 축방향 스플라인부의 스플라인 잇수는 내륜의 내측 축방향 단면에 구비된 단면 치형부의 잇수 보다 크게 형성될 수 있다.
