According to an embodiment of the present invention, a vehicle wheel bearing for rotatably mounting and supporting a vehicle wheel on a vehicle body is provided. A vehicle wheel bearing according to an embodiment of the present invention may include: a wheel hub configured to mount thereon a vehicle wheel; at least one inner race press-fitted and mounted on the wheel hub; an outer race mounted in a vehicle body; at least one transmission body mounted at the radially inner side of the outer race; and a sealing member mounted between the outer race and the wheel hub or the inner race. According to an embodiment of the present invention, the sealing member includes a frame mounted on the outer race and an elastic sealing part attached to the frame, the elastic sealing part includes an over-molded part extending from the frame and closely mounted on the outer race and a protrusion extending from the over-molded part and having an end to come into contact with the outer race, and the protrusion may be configured such that the end thereof comes into contact with the outer race at a position spaced apart from the over-molded part so as to define a space part by the over-molded part, the protrusion, and the outer race.
Selon un mode de réalisation, la présente invention concerne un palier de roue de véhicule destiné à monter et à supporter de façon rotative une roue de véhicule sur une carrosserie de véhicule. Le palier de roue de véhicule selon un mode de réalisation de la présente invention peut comprendre : un moyeu de roue conçu pour accueillir une roue de véhicule ; au moins une bague intérieure ajustée par pression et montée sur le moyeu de roue ; une bague extérieure montée sur une carrosserie de véhicule ; au moins un corps de transmission monté sur le côté radialement intérieur de la bague extérieure ; et un élément d'étanchéité monté entre la bague extérieure et le moyeu de roue ou la bague intérieure. Selon un mode de réalisation de la présente invention, l'élément d'étanchéité comprend un cadre monté sur la bague extérieure et une partie d'étanchéité élastique fixée au cadre, la partie d'étanchéité élastique comprend une partie surmoulée s'étendant à partir du cadre et montée étroitement sur la bague extérieure et une saillie s'étendant à partir de la partie surmoulée et dotée d'une extrémité pour entrer en contact avec la bague extérieure, et la saillie peut être conçue de telle sorte que son extrémité vienne en contact avec la bague extérieure à une position espacée de la bague extérieure de la partie surmoulée de manière à définir une partie d'espace par la partie surmoulée, la saillie et la bague extérieure.
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, 휠허브에 압입되어 장착되는 하나 이상의 내륜과, 차량의 차체에 장착되는 외륜과, 외륜의 반경방향 내측에 장착되는 하나 이상의 전동체와, 외륜과 휠허브 또는 내륜 사이에 장착되는 씰링부재를 포함하여 구성될 수 있다. 본 발명의 일 실시예에 따르면, 씰링부재는 외륜에 장착되는 프레임과 프레임에 부착된 탄성 씰링부를 포함하고, 탄성 씰링부는 프레임으로부터 연장하여 외륜에 밀착하여 장착되는 오버몰드부와 오버몰드부로부터 연장하며 끝단이 외륜에 접촉하는 돌출부를 포함하고, 돌출부는 오버몰드부로부터 이격된 위치에서 끝단이 외륜에 접촉해 오버몰드부, 돌출부, 외륜 사이에 공간부가 형성되도록 구성될 수 있다.
