본 발명의 일 실시예에 따르면, 차량의 휠을 차체에 회전 가능하게 장착하여 지지하는 휠베어링 조립체가 제공된다. 본 발명의 일 실시예에 따른 차량용 휠베어링 조립체는 차량의 휠이 장착되어 차량의 휠과 함께 회전하는 휠허브와; 휠허브의 외주면에 압입되어 장착되는 하나 이상의 내륜과; 차체측 부재에 장착되어 고정되는 외륜과; 휠허브 및 내륜을 외륜에 대해 상대회전 가능하게 지지하는 복수의 전동체와; 휠허브에 결합되는 등속조인트를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 등속조인트는 숄더부의 외측 축방향 단면이 휠허브 또는 내륜의 내측 축방향 단면에 접촉하여 장착되도록 구성될 수 있고, 등속조인트의 숄더부의 외측 축방향 단면과 휠허브 또는 내륜의 내측 축방향 단면 사이의 접촉면 중 어느 일측에는 저마찰 금속 코팅층이 구비되도록 구성될 수 있다.

    According to an example embodiment of the present invention, there is provided a wheel bearing assembly for rotatably mounting and supporting a wheel of a vehicle on a vehicle body. According to an example embodiment of the present invention, the wheel bearing assembly may comprise: a wheel hub to which the wheel of the vehicle is mounted and configured to rotate together with the wheel of the vehicle; at least one inner ring mounted on an outer circumferential surface of the wheel hub in a press-fitting manner; an outer ring mounted on and fixed to a vehicle-body-side member; a plurality of rolling elements configured to rotatably support the wheel hub and the inner ring relative to the outer ring; and a constant velocity joint coupled to the wheel hub. According to an example embodiment of the present invention, the constant velocity joint may be configured such that an outer axial end surface of a shoulder portion is in contact with an inner axial end surface of the wheel hub or the inner ring, and a low-friction metal alloy layer may be provided on one side of a contact surface between the outer axial end surface of the shoulder portion of the constant velocity joint and the inner axial end surface of the wheel hub or the inner ring.
