A secondary seal arrangement for a wheel bearing assembly, the wheel bearing assembly comprising: a fixed inner axle with a circumferential outer surface and a bearing inner race; an outer hub rotatable about the inner axle and having a circumferential inner surface and a bearing outer race; a rolling element disposed between the inner ring and the outer ring; and a primary seal (s) connected with the inner axle and sealingly engaged with the outer hub. The secondary sealing device includes a rigid annular body having: a radially inner end coupled with the inner hub; and a radially outer end spaced radially inwardly from a circumferential inner surface of the outer hub to define an annular gap between the body and the outer ring. The body is located between the primary seal and an axial end of the hub to provide a barrier configured to prevent contaminants from contacting the primary seal.
一种用于车轮轴承组件的副密封装置,所述车轮轴承组件包括:固定的内轮轴,带有圆周外表面和轴承内圈;外轮毂,能够绕着所述内轮轴旋转,并且具有圆周内表面和轴承外圈;滚动元件,布置在所述内圈与所述外圈之间;以及(多个)主密封件,与所述内轮轴连接并且与所述外轮毂密封地接合。所述副密封装置包括刚性环形主体,所述环形主体具有:径向内端部,与所述内轮毂联接;以及径向外端部,与所述外轮毂的圆周内表面在径向上向内间隔开,以在所述主体与所述外圈之间限定环形间隙。所述主体位于所述主密封件与所述轮毂的轴向端部之间,以提供被构造为防止污染物接触所述主密封件的屏障。
