A wheel bearing assembly includes: a fixed inner axle having at least one inner raceway; a rotatable outer hub disposed about the axle and having at least one outer raceway; and a rolling element arranged between the inner raceway and the outer raceway. An annular seal is disposed between the axle and the hub and positioned adjacent the inner raceway and the outer raceway. The shield is axially spaced from the seal such that the seal is arranged between the rolling element and the shield. The shield includes a rigid annular body having an outer radial end coupled with the outer hub, preferably by a plurality of couplings, and an inner radial end defining a central opening for receiving the axle and positioned adjacent to the inner axle or a component disposed on the axle. Thereby, the annular body substantially blocks the annular interior space to prevent matter from contacting the seal.

    一种车轮轴承组件包括:固定的内轮轴,具有至少一个内滚道;可旋转的外轮毂,绕着轮轴布置并且具有至少一个外滚道;以及滚动元件,布置在内滚道与外滚道之间。环形密封件布置在轮轴与轮毂之间并且邻近内滚道和外滚道定位。遮蔽件在轴向上与密封件间隔开,使得密封件布置在滚动元件与遮蔽件之间。遮蔽件包括刚性环形主体,刚性环形主体具有外径向端部和内径向端部,外径向端部与外轮毂联接,优选地,外径向端部通过多个联接部与外轮毂联接,内径向端部限定用于接纳轮轴的中心开口并且邻近内轮轴或布置在轮轴上的组件定位。由此,环形主体基本上阻挡环形内部空间,以防止物质接触密封件。
