Wheel hub for a corner assembly

1 . A wheel hub of a corner assembly for a vehicle wherein the wheel hub is attached to a stationary member through a bearing, a wheel is attached to the wheel hub, a rotor for a brake system is secured to the wheel hub and a caliper is attached to the stationary member, said wheel hub being characterized by a cylindrical body having an axial bore that extends from a first end to a second end, a peripheral surface with a first flange located adjacent said first end with the wheel being attached to said first flange, a second flange located adjacent said first flange with said rotor being attached to said second flange and a bearing surface that extends from said second end toward said second flange with said bearing being located on said bearing surface such that a perpendicular relationship is established between the axis of said bearing and faces on said rotor and as a result during rotation of said wheel hub a desired space relationship is maintained between first and second faces on said rotor and corresponding first and second friction members retained by said caliper.

2 . The wheel hub as recited in claim 1 wherein said first flange has a first plurality of axial openings for receiving a corresponding plurality of studs through which said wheel is attached to said first flange.

3 . The wheel hub as recited in claim 2 wherein said second flange has a second plurality of axial openings aligned with said first plurality of openings, said plurality of studs passing through said second plurality of openings and being fixed in said first plurality of openings to secure said wheel to said first flange.

4 . The wheel hub as recited in claim 3 wherein said second flange has a first radial section offset from a second radial section by an axial section, said offset section aligning said second radial section over said bearing to orient said rotor with respect to said caliper wherein said desired space is equal between said first and second faces on said rotor and corresponding first and second friction members.

5 . The wheel hub as recited in claim 4 wherein said second radial section has a third plurality of axial openings therein for receiving a plurality of fasteners through which said rotor is attached to said second flange.

6 . The wheel hub as recited in claim 4 wherein said second radial section has a plurality of radial slots on its periphery and a third plurality of axial openings interspersed between said plurality of radial slots, said rotor has a corresponding plurality of keys thereon that pass through said plurality of radial slots until a plurality of tabs engage said second radial section, said plurality of tabs having a fourth plurality of axial openings located therein; and fasteners that are inserted into said third and fourth plurality of openings to attach said rotor to said second radial section.

7 . A wheel hub of a corner assembly for a vehicle wherein the wheel hub is attached to an axle of a vehicle and to a stationary member through a bearing, a wheel is attached to the wheel hub, a rotor for a brake system is secured to the wheel hub and a caliper is attached to the stationary member, said wheel hub being characterized by a cylindrical body having an axial bore that extends from a first end to a second end, a peripheral surface with a first flange located adjacent said first end with the wheel being attach to said first flange, a second flange located adjacent said first flange with said rotor being attached to said second flange and a bearing surface that extends from said second end toward said second flange with said bearing being located on said bearing surface such that a perpendicular relationship is established between said axis of said bearing and faces on said rotor and as a result during rotation of said wheel hub a desired space relationship is maintained between first and second engagement faces on said rotor and corresponding first and second friction members retained by said caliper.

8 . A wheel hub of a corner assembly for a vehicle wherein the wheel hub is attached to an axle of a vehicle and to a stationary member through a bearing, a wheel is attached to the wheel hub, a rotor for a brake system is secured to the wheel hub and a caliper is attached to the stationary member, said wheel hub being characterized by a cylindrical body having an axial bore that extends from a first end to a second end, a peripheral surface with a first flange located adjacent said first end with the wheel being attached to said first flange, an annular ledge located adjacent said first flange with said rotor being located on said annular ledge and a bearing surface that extends from said second end toward said annular ledge with said bearing being retained on said bearing surface such that a perpendicular relationship is established between the axis of said bearing and first and second engagement faces on said rotor and as a result during rotation of said wheel hub a desired space relationship is maintained between said first and second engagement faces on said rotor and corresponding first and second friction members retained by said caliper.

9 . The wheel hub as recited in claim 8 wherein said annular ledge is characterized by an irregular surface such that said rotor is inhibited from rotating independently of said wheel hub.

10 . The wheel hub as recited in claim 9 wherein said annular ledge is located adjacent a radial face in achieving said perpendicular relationship between said rotor and said first and second friction members.
