Zusammenfassung:A wheel hub assembly (1) for an automotive vehicle has a spindle (14) with a flange (24) by which a wheel (15) is mounted, the spindle (4) being supported by a support member (2) and being rotated through a universal joint (8). Axially spaced inboard (77) and outboard (75) bearing members are positioned between the spindle (4) and the support member (2). The spindle (4) has a tapered raceway (36) forming a cone of the outboard bearing member (76), the raceway lying inboard of the flange (24). The outboard bearing member cone raceway (36) has no thrust rib at its large, outboard end, and a large radius is provided between the outboard end of the raceway and the flange. An outboard bearing member cup (58) has a raceway tapered complementarily to the cone raceway and a thrust rib (38) at its outboard end. Preferably, the inboard bearing member (77) has a cone (54) with no thrust rib, and a cup (56) with a thrust rib (39). L'invention concerne un ensemble de moyeu (1) de roue d'un véhicule automobile qui a un axe (14) doté d'une bride (24) qui permet de monter une roue (15), l'axe prenant appui sur un élément support (2) et tournant par le biais d'un joint de cardan (8). Espacés à l'intérieur (77) et à l'extérieur (75), des éléments paliers sont placés entre l'axe (4) et l'élément support (2). L'axe a un trajet de roulement conique (36) formant un cône de l'élément palier extérieur (76), le trajet de roulement s'étendant à l'intérieur de la bride (24). Le trajet de roulement conique (36) de l'élément palier extérieur n'est doté d'aucune nervure de poussée à sa grande extrémité extérieure, et un grand rayon est prévu entre l'extrémité extérieure du trajet de roulement et la bride. Une coquille (58) de l'élément palier extérieur a un trajet de roulement conique en complément au trajet de roulement du cône et une nervure de poussée (38) à son extrémité extérieure. De préférence, l'élément palier intérieur (77) a un cône (54) sans nervure de poussée, et une coquille (56) avec une nervure de poussée (39).
