According to one embodiment of the present invention, provided is a wheel bearing for mounting a wheel on a vehicle body to be rotatable and supporting the same. According to one embodiment of the present invention, the wheel bearing includes: a rotating element having a wheel mounted thereon to be rotated together with the wheel; a non-rotating element mounted on a chassis part of a vehicle to be fixed to a vehicle body; at least one electric motion body interposed between the rotating element and the non-rotating element to support the rotating element to the non-rotating element to be rotatable; and a center locking member used for mounting the wheel on the rotating element. According to one embodiment of the present invention, the rotating element can include a wheel-side mounted flange extended outward in a radial direction, and a wheel pilot extended from the wheel-side mounted flange to a wheel side. According to one embodiment of the present invention, the center locking member is formed to be coupled with the wheel pilot, and at least one locking pin placed to be extended in a radial direction is formed to be combined with a loosening prevention part formed on an inner circumference surface of a wheel hub to prevent the loosening of the center locking member.

    본 발명의 일 실시예에 따르면, 휠을 차체에 회전 가능하게 장착하여 지지하는 휠베어링이 제공된다. 본 발명의 일 실시예에 따른 휠베어링은 휠이 장착되어 휠과 함께 회전하는 회전요소와, 차량의 샤시 부품에 장착되어 차체에 고정되는 비회전요소와, 회전요소와 비회전요소 사이에 개재되어 회전요소를 비회전요소에 대해 회전 가능하게 지지하는 하나 이상의 전동체와, 회전요소에 휠을 장착하는데 이용되는 센터로킹부재를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 회전요소는 반경방향 외측으로 연장하는 휠측 장착 플랜지와 휠측 장착 플랜지로부터 휠측으로 연장하는 휠파일럿을 구비할 수 있다. 본 발명의 일 실시예에 따르면, 센터로킹부재는 휠파일럿에 체결되도록 구성되며, 반경방향으로 연장하도록 배치된 하나 이상의 잠금핀이 휠허브의 내주면에 형성된 풀림방지부에 결합되어 센터로킹부재의 풀림을 방지하도록 구성될 수 있다.
