본 발명의 일 실시예에 따르면, 차량의 차륜을 차체에 회전 가능하게 장착하여 지지하는 차량용 휠베어링이 제공된다. 본 발명의 일 실시예에 따른 차량용 휠베어링은 차량의 차륜이 장착되는 휠허브와, 휠허브의 반경방향 외측에 배치되며 차량의 차체에 장착되는 외륜과, 휠허브와 외륜 사이에 배치되는 전동체와, 휠허브와 외륜 사이를 씰링하는 씰링부재를 포함하고, 씰링부재는 휠허브에 장착되어 고정되는 슬링거와, 슬링거에 부착되는 탄성 씰링부를 포함하도록 구성될 수 있다. 본 발명의 일 실시에에 따르면, 슬링거는 휠허브의 외주면에 압입되어 장착되는 압입부와, 압입부로부터 반경방향 외측으로 연장하여 형성되는 경방향 연장부와, 경방향 연장부의 반경방향 외측 단부로부터 축방향으로 연장하는 축방향 연장부와, 압입부의 내측 단부로부터 반경방향 외측으로 연장하는 보조 연장부를 포함하고, 경방향 연장부, 압입부, 보조 연장부에 의해 휠베어링의 회전축 주위로 환형의 공간부가 형성되도록 구성될 수 있다.

    According to an embodiment of the present invention, provided is a vehicle wheel bearing for rotatably mounting and supporting a vehicle wheel on a vehicle body. A vehicle wheel bearing, according to an embodiment of the present invention, comprises: a wheel hub on which a vehicle wheel is mounted; an outer ring disposed on a radially outer side of the wheel hub and mounted on the vehicle body; a rolling element disposed between the wheel hub and the outer ring; and a sealing member for sealing a gap between the wheel hub and the outer ring. The sealing member includes a slinger mounted on and fixed to the wheel hub, and an elastic sealing portion attached to the slinger. According to one embodiment of the present invention, a slinger includes: a press-fitting portion which is press-fitted to and mounted on the outer circumferential surface of the wheel hub; a radial extension portion formed by extending radially outward from the press-fitting portion; an axial extension portion extending in an axial direction from the radially outer end of the radial extension portion; and an auxiliary extension portion extending radially outward from the inner end of the press-fitting portion. An annular space portion is formed around the axis of rotation of the wheel bearing by the radial extension portion, the press-fitting portion, and the auxiliary extension portion.
