Hub assembly for automotive vehicles

摘要

A steering knuckle is supported on a road wheel of an automotive vehicle by a hub assembly which includes a housing fitted into a bore in the knuckle and hub having a flange to which the road wheel is attached and also a spindle which projects from the flange into the housing. The bearing has cones which fit over the spindle between a shoulder on the hub flange and an integrally formed abutment on the other end of the spindle. The ends of the bearing contain seals which exclude contaminants from the interior of the bearing. A slinger is fitted to the spindle and may be captured between the cone at the inboard end of the bearing and the abutment. The slinger extends outwardly past the spindle abutment and seal at the inboard end of the bearing and has a circular peripheral edge which lies close to the surface of the bore in the steering knuckle, thus providing an additional barrier to exclude contaminants from the bearing.
