Abstract: A bearing assembly having improved impact Brinell resistance is provided. Due to a controlled gap between a rotating component and a non-rotating component or a vehicle suspension structure, the non-rotating component or the vehicle suspension structure is permitted to share impact loads caused by a sufficient side impact to the rotating component, thus preventing excessive loads from being transmitted to rolling elements, and providing greater resistance against Brinell impact damage that would generate a noise and/or vibration condition in the bearing assembly. The width of the controlled gap and of the area of potential contact between the rotating component and the vehicle suspension structure or the non-rotating component are optimized to increase impact Brinell resistance while avoiding excessive contact between the rotating component and the non-rotating component or the vehicle suspension structure during extreme cornering maneuvers.

Abstract: A support member (14) for rotatably coupling a first element to a second element. The support member includes a sleeve (50) for rotatably supporting the first element, and a flange (56) having a concave central portion. The flange (56) is coupled to the sleeve (50). The flange (56) has bearing surfaces (68a, 68b) formed thereon along which the flange (56) is mounted to the second element. In one embodiment, the first element is a spindle (12) of a vehicle wheel assembly (11) and is rotatably supported in the sleeve (50) by rollable bearing elements positioned therein. Multiple tapered lobes (64) extend outwardly from the sleeve (50), and the support member (14) is mounted to a vehicle via bearing surfaces (68a, 68b) along the lobes (64).
