Abstract
A brake rotor assembly and a method of assembly. The brake rotor assembly includes a brake rotor, a tone ring, and a rivet. The rivet is disposed in a hole in the brake rotor and a hole in the tone ring and fixedly secures the tone ring to the brake rotor.
Claims16
A brake rotor assembly comprising:
- a brake rotor that encircles a brake rotor axis and has a mounting flange, wherein the mounting flange of the brake rotor extends toward the brake rotor axis and has a through hole;
- a tone ring that engages the mounting flange of the brake rotor and that defines a tone ring hole;
- and
- a rivet that is disposed in the through hole and the tone ring hole and that fixedly secures the tone ring to the brake rotor,
- wherein the mounting flange has a first side that faces toward the tone ring and a second side that is disposed opposite the first side, and the through hole extends from the first side to the second side and
- wherein the through hole extends along a through hole axis and the mounting flange has a step surface that is axially positioned with respect to the through hole axis between the first side and the second side.

A method of assembling a brake rotor assembly, the method comprising:
- positioning a tone ring against a brake rotor such that a tone ring hole is aligned with a through hole in the brake rotor to permit insertion of a rivet;
- inserting the rivet into the through hole and the tone ring hole, wherein the rivet extends along a rivet axis;
- and
- upsetting the rivet to form a rivet head and to expand a portion of the rivet that is disposed in the through hole away from the rivet axis and into contact with the brake rotor in the through hole and to expand a portion of the rivet that is disposed the tone ring hole away from the rivet axis and into contact with the tone ring in the tone ring hole;
- wherein the rivet has a first rivet head and inserting the rivet includes positioning the first rivet head into contact with a mounting flange of the brake rotor;
- and
- wherein the through hole extends along a through hole axis, the mounting flange has a first side that contacts the tone ring, a second side that is disposed opposite the first side, and a step surface that is axially positioned along the through hole axis between the first side and the second side, and inserting the rivet includes positioning the first rivet head into contact with the step surface.
