Brake rotor and tone ring assembly
First Claim
1. A wheel assembly comprising:
- a wheel hub defining an axis of rotation;
a brake rotor having a first set of mounting bosses and a second set of mounting bosses that are both circumferentially spaced about said axis of rotation wherein said brake rotor includes an inner circumferential portion with an opening surrounding an outer surface of said wheel hub, an outer circumferential portion defining a braking surface, and a wall portion interconnecting said inner circumferential portion with said outer circumferential portion, said first set of mounting bosses being formed within said wall portion and said second set of mounting bosses being formed within said inner circumferential portion; and
a tone ring mounted to said brake rotor wherein said first set of mounting bosses provides a first mount interface between said tone ring and said brake rotor and said second set of mounting bosses provides a second mount interface between said brake rotor and said wheel hub, said first mount interface being independent from said second mount interface such that said brake rotor is removable from said wheel hub without having to remove said tone ring from said brake rotor and such that said tone ring is removable from said brake rotor without having to remove said brake rotor from said wheel hub.

Abstract
A wheel assembly includes a wheel hub and brake rotor that rotate about an axis. The brake rotor includes an outer circumferential surface area that cooperates with brake pads to provide braking for the wheel assembly. The brake rotor includes an inner circumferential surface area that has two different sets of mounting bosses. A first set of mounting bosses is spaced circumferentially about the axis and provides a mounting interface for a tone ring as used in an anti-lock brake system. A second set of mounting bosses is also spaced circumferentially about the axis but does not overlap the first set of mounting bosses. The second set of mounting bosses provides a mounting interface for securing a brake rotor and tone ring assembly to the wheel hub.

6. A method for assembling a wheel comprising the steps of:
-
(a) forming a first mount interface in a brake rotor to include a first plurality of openings, and mounting a tone ring to the brake rotor at the first mount interface; (b) forming a second mount interface in the brake rotor to include a second plurality of openings, and mounting the brake rotor to a wheel hub at the second mount interface that is independent from the first mount interface such that the brake rotor is removable from the wheel hub without having to remove the tone ring from the brake rotor and such that the tone ring is removable from the brake rotor without having to remove the brake rotor from the wheel hub; and (c) inserting a first set of fasteners through the first plurality of openings to secure the tone ring and brake rotor together, and inserting a second set of fasteners through the second plurality of openings to secure the brake rotor and wheel hub together. - View Dependent Claims (7, 8, 9, 10)
