A hub bearing unit includes an inner ring having inboard and outboard axial ends and a bearing inner race on an outer surface. An outer ring disposed about the inner ring has inboard and outboard axial ends and a bearing outer race on an inner surface. One ring is coupled with a wheel and rotatable about an axis, and the other ring is fixedly coupled with a frame. An annular displacement limiter extends radially from one ring and has a circumferential stop surface spaced radially from a surface of the other ring. The stop surface engages with the ring surface when the ring displaces radially relative to the other ring. A seal includes an annular sealing member coupled with one ring and is sealingly engageable with the limiter or is mounted on the limiter and sealingly engageable with one ring or a rigid seal member coupled with one ring.
一种轮毂轴承单元包括内圈,所述内圈具有轴向内侧端部和轴向外侧端部以及外表面上的轴承内滚道。绕着所述内圈布置的外圈具有轴向内侧端部和轴向外侧端部以及内表面上的轴承外滚道。一个圈与车轮联接并且可绕着轴线旋转,并且另一个圈与框架固定地联接。环形位移限制件从一个圈在径向上延伸,并且具有与另一个圈的表面在径向上间隔开的圆周止动表面。当一个圈相对于另一个圈在径向上移位时,所述止动表面与圈表面接合。密封件包括环形密封构件,所述环形密封构件与一个圈联接并且可与所述限制件密封地接合,或者安装在所述限制件上并且可与一个圈或与和一个圈联接的刚性密封构件密封地接合。
