A wheel bearing assembly according to one embodiment of the present invention comprises a wheel hub, one or more inner wheels, an outer wheel, and one or more bearings, wherein, at the end of the vehicle body-side interior of the wheel hub, an accommodating space for accommodating a universal joint is provided, and along the inner circumferential surface of the accommodating space, a plurality of recesses, spaced apart along the circumferential direction, for accommodating a rotating element of the universal joint may be provided. According to one embodiment of the present invention, a first heat-treated hardened part is provided on the inner circumferential surface of the accommodating space, and the first heat-treated hardened part may comprise a part with which the rotating element of the universal joint comes into contact. According to one embodiment of the present invention, a second heat-treated hardened part is provided on the outer circumferential surface of the wheel hub, and the first and second heat-treated hardened parts may be formed so as not to overlap with each other. Un ensemble roulement de roue selon un mode de réalisation de la présente invention comprend un moyeu de roue, une ou plusieurs roues internes, une roue externe et un ou plusieurs roulements. Au niveau de l'extrémité de l'intérieur côté carrosserie de véhicule du moyeu de roue, un espace de réception pour recevoir un joint universel est prévu, et le long de la surface circonférentielle interne de l'espace de réception, une pluralité d'évidements, espacés le long de la direction circonférentielle, pour recevoir un élément rotatif du joint universel peuvent être prévus. Selon un mode de réalisation de la présente invention, une première pièce durcie traitée thermiquement est prévue sur la surface circonférentielle interne de l'espace de réception, et ladite première pièce durcie traitée thermiquement comporte une partie avec laquelle l'élément rotatif du joint universel vient en contact. Selon un mode de réalisation de la présente invention, une seconde pièce durcie traitée thermiquement est prévue sur la surface circonférentielle externe du moyen de roue, et lesdites première et seconde pièces durcies traitées thermiquement peuvent être formées de manière à ne pas se chevaucher l'une l'autre. 본 발명의 일 실시예에 따른 휠베어링 조립체는 휠허브와 하나 이상의 내륜과 외륜과 하나 이상의 전동체를 포함하고, 휠허브의 차체측 단부 내측에는 등속조인트를 수용하기 위한 수용공간이 형성되고, 수용공간의 내주면에는 등속조인트의 회전요소가 수용되는 리세스가 원주방향을 따라 이격되어 복수로 형성되도록 구성될 수 있다. 본 발명의 일 실시예에 따르면, 수용공간의 내주면에는 제1 열처리 경화부가 형성되고, 제1 열처리 경화부는 등속조인트의 회전요소가 접촉되는 부분을 포함하여 형성될 수 있다. 본 발명의 일 실시예에 따르면, 휠허브의 외주면에는 제2 열처리 경화부가 형성되고, 제1 열처리 경화부와 제2 열처리 경화부는 서로 중첩되지 않도록 형성될 수 있다.
