Wheel hub

A wheel hub of a corner assembly of a vehicle wherein the wheel hub is attached to a stationary member though 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 having a peripheral surface with a flange for receiving the wheel and the rotor and a bearing surface on which the bearing is located such that a perpendicular space relationship is established between first and second faces on said rotor first and second friction members retained by the caliper, said flange being characterized by a scalloped torque receiving surface located adjacent a first radial surface that extends from an annular surface and a second radial surface that extends from the torque receiving surface to an annular peripheral surface;

• and wherein said rotor is characterized by a first radial member that is offset from a second radial member on which said first and second faces are located by a cylindrical member, said first radial member having an inner peripheral surface with a plurality of arcuate projections thereon that are complementary to said scalloped torque receiving surface on said flange, said cylindrical member having an inner arcuate groove located between said first radial member and said second radial member, said arcuate projections being mated with said scalloped torque receiving surface such that said first radial member engages said second radial surface to establish said perpendicular space relationship;
• and clip means attached to said annular peripheral surface on said flange and engaging said arcuate groove to provide a resultant force that resiliently urges said first radial member toward said second radial surface to sustain said perpendicular relationship.

A wheel hub of a corner assembly of a vehicle wherein the wheel hub is attached to a stationary member though a bearing, a rim for a wheel is fixed to the wheel hub, a rotor for a brake system is secured to the wheel hub and a caliper is fixed to the stationary member, said wheel hub having a peripheral surface with a flange for receiving the rim for the wheel and the rotor and a bearing surface on which the bearing is located such that a perpendicular space relationship is established between first and second faces on said rotor and first and second friction members retained by the caliper, said flange being characterized by a scalloped torque receiving surface located adjacent a first radial surface that extends from an annular surface and second radial surface that extends from said scalloped torque receiving surface to an annular peripheral surface;

• and wherein said rotor is characterized by a first radial member that is offset from a second radial member on which said first and second faces are located by a cylindrical member, said first radial member having an inner peripheral surface with a plurality of arcuate projections thereon that are complementary to said scalloped torque receiving surface on said flange, said cylindrical member having a plurality of arcuate slots on an inner surface located between said first radial member and said second radial member, said arcuate projections being mated with said scalloped surface such that said first radial member engages said second radial surface to establish said perpendicular space relationship;
• and clip means attached to said annular peripheral surface on said flange and engaging said cylindrical member though said plurality of arcuate slots to provide a resultant force that resiliently urges said first radial member toward said second radial surface to sustain said perpendicular relationship.
