Abstract
A wheel end (A, B, C) for mounting a road wheel (W) of an automotive vehicle includes a knuckle (2) having a bearing cavity (20, 24, 26), a hub having a spindle (40) that projects into the bearing cavity of the knuckle and a flange (42) at one end of the spindle, with the road wheel being attached to it, and a bearing (6) located within the bearing cavity and around the spindle of the hub to enable the hub to rotate on the spindle. The bearing includes tapered rollers (72) organized in outboard and inboard rows as well as raceways (60, 76, 82) along which they roll. The rollers of the inboard row roll along tapered raceways on a cup pressed into the bearing cavity and a cone (66) pressed over the spindle. The bearing is closed at that end by an inboard seal (12, 174, 184, 208) which includes a case (130) pressed into a bore (24) that forms part of the bearing cavity, a shield (132) pressed over a thrust rib at the end of the cone, and a seal element (134, 178) bonded to the case and establishing a fluid barrier with the shield. The shield has a wall (142, 188) which serves as a tone ring, and this ring is monitored by a sensor (14, 186, 212) which is fitted to the knuckle at the in…
