The present invention relates to a wheel bearing having a wheel speed sensor having a plurality of sensing units. According to one embodiment of the present invention, provided is the wheel bearing for rotationally mounting and supporting a wheel of a vehicle on a vehicle body. The wheel bearing according to one embodiment of the present invention may comprise: a rotating element mounted on the wheel and rotating together with the wheel; a non-rotating element mounted on and fixed to the vehicle body; at least one rolling body interposed between the rotating element and the non-rotating element; a sensor target mounted on the rotating element and rotating together with the rotating element; and a wheel speed sensor disposed adjacent to the sensor target to detect a rotation speed of the rotating element. According to one embodiment of the present invention, the wheel speed sensor includes a first sensing unit and a second sensing unit for sensing a change in a magnetic field due to rotation of the sensor target. The second sensing unit may be configured to be disposed to be spaced apart from the first sensing unit in the longitudinal and width directions of the wheel speed sensor.
본 발명의 일 실시예에 따르면, 차량의 차륜을 차체에 회전 가능하게 장착하여 지지하는 휠베어링이 제공된다. 본 발명의 일 실시예에 따른 휠베어링은 차륜에 장착되어 차륜과 함께 회전하는 회전요소와, 차체에 장착되어 고정되는 비회전요소와, 회전요소와 비회전요소 사이에 개재되는 하나 이상의 전동체와, 회전요소에 장착되어 회전요소와 함께 회전하는 센서타겟과, 센서타겟에 인접하게 배치되어 회전요소의 회전속도를 감지하는 휠속도 센서를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 휠속도 센서는 센서타겟의 회전에 의한 자기장의 변화를 감지하는 제1 센싱부 및 제2 센싱부를 포함하고, 제2 센싱부는 제1 센싱부로부터 휠속도 센서의 길이방향 및 폭방향으로 이격되어 배치되도록 구성될 수 있다.
