The present invention provides a wheel bearing which rotatably mounts a wheel on a vehicle body to support the wheel. In accordance with one embodiment of the present invention, the wheel bearing comprises: a rotary element allowing a wheel to be mounted thereon to rotate with the wheel; a nonrotary element mounted on a chassis part of a vehicle to be fixed on a vehicle body; one or more rolling bodies interposed between the rotary element and the nonrotary element to support the rotary element to be rotated with respect to the nonrotary element; and a center locking member used to mount the wheel on the rotary element. In accordance with one embodiment of the present invention, the rotary element can include a wheel hub with a wheel-side mounting flange. In accordance with one embodiment of the present invention, the center locking member can include: a locking screw coupled to the wheel-side end of the wheel hub; a locking cone coupled to the radial center of the wheel hub at a position closer to the vehicle body than the locking screw; and a locking bolt fastening the locking screw and the locking cone. In accordance with one embodiment of the present invention, the locking screw has an end surface gear tooth unit on the vehicle body-side axial end surface, and the end surface gear tooth unit is engaged with a corresponding end surface gear tooth unit provided on the wheel-side axial end surface of the locking cone to fasten the locking screw to the locking cone.

    본 발명의 일 실시예에 따르면, 휠을 차체에 대해 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 휠측 장착 플랜지를 구비하는 휠허브를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 센터로킹부재는 휠허브의 휠측 단부에 결합되는 잠금 스크류와; 잠금 스크류 보다 차체측 위치에서 휠허브의 반경방향 중심부에 결합되는 잠금콘과; 잠금 스크류와 잠금콘을 체결하는 잠금볼트를 포함할 수 잇다. 본 발명의 일 실시예에 따르면, 잠금 스크류는 차체측 축방향 단면에 단면 치형부를 구비해 단면 치형부가 잠금콘의 휠측 축방향 단면에 구비된 대응 단면 치형부에 치형결합되어 잠금콘과 체결되도록 구성될 수 있다.
