A seal assembly for a wheel bearing assembly includes an inner axle and a rotatable outer hub disposed about the axle. The seal assembly includes an annular inner shell having an axial portion deployable about the axle and a radial portion extending radially outward from the axial portion. A seal is coupled with the hub and has a plurality of sealing lips sealingly engageable with the annular inner shell. Further, the annular slinger has an inner radial end coupled or integrally formed with the annular inner shell and an outer radial end including an outer axial portion spaced radially inward from the inner circumferential surface of the hub to define an annular labyrinth gap. The slinger includes a central portion that is at least partially frustoconical and extends between the inner and outer radial ends to block an annular space between the inner shell and the seal.
一种用于车轮轴承组件的密封组件,车轮轴承组件包括内轮轴以及绕着轮轴布置的可旋转的外轮毂。密封组件包括环形内壳,环形内壳具有能够绕着轮轴布置的轴向部分和从轴向部分在径向上向外延伸的径向部分。密封件与轮毂联接并且具有能够与环形内壳密封地接合的多个密封唇。此外,环形抛油环具有内径向端部和外径向端部,内径向端部与环形内壳联接或一体地形成,外径向端部包括外轴向部分,外轴向部分从轮毂的内圆周表面在径向上向内间隔开以限定环形迷宫间隙。抛油环包括中心部分,中心部分至少部分地为截头圆锥形,并且在内径向端部与外径向端部之间延伸,以阻挡内壳与密封件之间的环形空间。
