1. 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.

Abstract
A mounting system for disc brake rotors. Drive pins are mounted to a wheel hub. Alignment bushings having outer flanges defining a channel are slidably held in slots in a disc brake rotor, with the rotor engaging the bushing channel. The alignment bushings are each mounted on a drive pin inserted through a hole in the alignment bushing. Drag rings prevent unwanted movement between the alignment bushings and the drive pins. The drag rings can be mounted in grooves in the alignment bushings or, alternatively, in grooves on the drive pins. Retaining rings on the drive pins prevent the bushings from coming off of the drive pins.

9. A disc brake rotor mounting system comprising:
-
a rotor having a plurality of slots; a plurality of alignment bushings, each configured to be slidably insertable into one of said slots in said rotor and each having a drive hole therein; a plurality of drive pins, each configured to be mountable on a hub and to be slidably insertable into the drive hole of one of said alignment bushings; and a plurality of drag rings, each said drag ring located between one of said drive pins and the alignment bushing into which said one drive pin is inserted, 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 ma 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. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 22)

17. A method of installing a disc-drive rotor onto a hub comprising:
-
mounting a plurality of drive pins on said hub; inserting a plurality of alignment bushings into respective slots in a rotor; mounting said rotor onto said hub by inserting each of said drive pins into a hole in a respective one of said alignment bushings; inserting a drag ring between each of said drive pins and the associated alignment bushing into which the drive pin is inserted, 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 maybe 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; and securing said rotor to said hub by installing a retaining ring on each of said drive pins. - View Dependent Claims (18, 19, 20)
