Patent ID: 6988598

Claim:
A wheel assembly comprising: a hub; a plurality of drive pins mounted on said hub; a rotor having a plurality of slots; a plurality of alignment bushings, each said alignment bushing slidably inserted into one of said slots in said rotor, each said alignment bushing slidably held by one of said drive pins; and a plurality of drag rings, each said drag ring located between one of said alignment bushings and the drive pin by which said one alignment bushing is held, each said drag ring resisting relative axial movement between the associated alignment bushing and drive pin, whereby, when said rotor is engaged by calipers during braking, the resistance provided by the drag ring may be overcome allowing the associated alignment bushing to move axially relative to the associated drive pin to a position in which the forces applied by the calipers to the opposed sides of the rotor are balanced and, when the calipers are released, the resistance provided by the drag ring maintains the relative axial positions of the associated alignment bushing and drive pin.
