Patent ID: 7484892

Claim:
A wheel bearing assembly composed of inner and outer bearing rings, one of which is intended to rotate and the other of which is intended to remain stationary, sets of rolling elements between the rings and in angular contact with tracks defined by the rings, the sets of rolling elements being spaced in the direction of the axis of rotation with each set of rolling elements retained by a cage and a sensing arrangement composed of at least two annular encoders with alternate north and south magnetic poles and at least two sensors operably associated with the encoders and each serving to provide electrical signals generated by the passage of the poles of the associated encoder; wherein one of the encoders is mounted on the rotatable one of the bearing rings and, the other of the encoders is mounted on one of the cages and wherein the inner bearing ring is secured onto a wheel hub, a cover is located on the outer bearing ring to enclose the sensors which are carried by an axial portion of the cover.
