ABSTRACT:
A package bearing includes a nonrotatable outer bearing ring having flanges along which it is attached to the suspension system of a vehicle, a rotatable inner bearing ring located within the outer ring and having a flange to which a road wheel is attached, and tapered rollers arranged in two rows between the outer and inner rings. The large ends of rollers on the outboard row bear against a rib at the flange on the inner ring, while the large ends of the rollers of the inboard row bear against a rib ring that is formed as a separate element and is subsequently connected to one of the rings. Between its inboard and outboard raceways the inner ring has a cylindrical intervening surface, the diameter of which exceeds the largest diameter on the inboard raceway of the inner ring. This enables an encoder ring to advance over the inboard raceway, and to be pressed over the intervening surface to its final position. Thereafter, the rollers of the inboard row are likewise advanced over the large end of the inboard raceway for the inner ring, all while confined in a cage--but the cage has breaks in its small end ring to enable it to expand and accommodate the large end of the raceway. Then the separate rib ring is secured against one of the rings at the large end of the inboard raceway for that ring. The outer ring carries a sensor which monitors the encoder ring, producing an electrical signal which reflects the angular velocity of the encoder ring.
