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 전동체와; 휠허브와 외륜 사이의 공간을 씰링하는 아웃보드측 씰링부재와; 내륜의 일측에 장착되어 내륜과 함께 회전하는 타겟링과; 차량의 작동 상태에 대한 정보를 검출하는 센서 조립체를 포함하도록 구성될 수 있다. 본 발명의 일 실시예에 따르면, 센서 조립체는 차량의 휠과 함께 회전하는 타겟링의 센서타겟에 의해 발생하는 자기장의 변화를 검출해 휠의 회전 속도를 측정하는 휠속도 센싱부를 포함할 수 있고, 센서 조립체의 일측에는 외부의 이물질이 내부로 유입되는 것을 방지하는 씰링부가 구비되도록 구성될 수 있다.

    According to an embodiment of the present invention, provided is a vehicle wheel bearing configured such that a vehicle wheel is rotatably mounted to and supported by a vehicle body. The vehicle wheel bearing according to an embodiment of the present invention may include: a wheel hub provided with a wheel-mounting flange; an inner ring mounted on the outer circumferential surface of the wheel hub; an outer ring provided with a vehicle body-side mounting flange; a plurality of rolling elements that support the wheel hub and the inner ring so that the wheel hub and the inner ring can rotate relative to the outer ring; an outboard-side sealing member that seals a space between the wheel hub and the outer ring; a target ring mounted on one side of the inner ring and rotating together with the inner ring; and a sensor assembly that detects information about an operating state of the vehicle. According to an embodiment of the present invention, the sensor assembly may include a wheel speed sensing unit that measures the rotation speed of the wheel by detecting changes in the magnetic field generated by a sensor target of the target ring that rotates together with the vehicle wheel. A sealing portion for preventing external foreign substances from entering inside is provided on one side of the sensor assembly.
