Abstract

A brake rotor having first and second panels and first and second sets of mounting flanges. The first set of mounting flanges may extend from the first panel and may be spaced apart from the second panel. The second set of mounting flanges may extend from the second panel and may be spaced apart from the first set of mounting flanges.

First claim

What is claimed is:

1. A brake rotor comprising:
a first panel that extends around an axis;
a second panel that is spaced apart from the first panel and extends around the axis, wherein the first panel and the second panel cooperate to at least partially define a rotor opening;
a first set of mounting flanges that extend from the first panel into the rotor opening and are spaced apart from the second panel;
a second set of mounting flanges that extend from the second panel into the rotor opening, wherein the second set of mounting flanges is spaced apart from the first set of mounting flanges; and
a reinforcement feature that extends from the first panel to a member of the first set of mounting flanges, wherein the reinforcement feature is spaced apart from the second panel.

2. The brake rotor of claim 1 wherein each member of the second set of mounting flanges is spaced apart from the first panel.

3. The brake rotor of claim 1 further comprising a plurality of vanes that extend from the first panel to the second panel and are arranged around the first set of mounting flanges and the second set of mounting flanges, wherein the vanes are spaced apart from the first set of mounting flanges and the second set of mounting flanges.

4. The brake rotor of claim 1 wherein the first set of mounting flanges and the second set of mounting flanges are arranged in an alternating pattern around the axis.

5. The brake rotor of claim 4 wherein each member of the second set of mounting flanges is disposed between two different members of the first set of mounting flanges.

6. The brake rotor of claim 1 wherein a tone ring mount extends from the reinforcement feature.

7. The brake rotor of claim 1 wherein the reinforcement feature is disposed in the rotor opening and extends from the first panel toward the axis.

8. The brake rotor of claim 1 wherein the reinforcement feature is disposed between a pair of mounting holes that is provided with the member of the first set of mounting flanges.

9. The brake rotor of claim 1 wherein each member of the second set of mounting flanges has an inner flange side that faces toward the axis and an outer flange side that is disposed opposite the inner flange side, wherein the outer flange side extends from the second panel and is partially received inside a portion of the rotor opening defined by the first panel.

10. The brake rotor of claim 9 wherein the outer flange side is disposed in a nonparallel relationship with the inner flange side.

11. A brake rotor comprising:
a first panel that extends around an axis;
a second panel that is spaced apart from the first panel and extends around the axis, wherein the first panel and the second panel cooperate to at least partially define a rotor opening;
a first set of mounting flanges that extend from the first panel into the rotor opening and are spaced apart from the second panel; and
a second set of mounting flanges that extend from the second panel into the rotor opening, wherein the second set of mounting flanges is spaced apart from the first set of mounting flanges;
wherein each member of the first set of mounting flanges has an inner flange side that faces toward the axis and an outer flange side that is disposed opposite the inner flange side, wherein the outer flange side extends from the first panel and is partially received inside a portion of the rotor opening defined by the second panel.

12. The brake rotor of claim 11 wherein the outer flange side is disposed in a nonparallel relationship with the inner flange side.

13. The brake rotor of claim 11 wherein a reinforcement feature extends from the first panel to a member of the second set of mounting flanges, wherein the reinforcement feature is spaced apart from the second panel.

14. The brake rotor of claim 13 wherein the member of the second set of mounting flanges is spaced apart from the first panel.

15. The brake rotor of claim 13 wherein the reinforcement feature is disposed in the rotor opening and extends from the first panel toward the axis.

16. The brake rotor of claim 13 wherein the reinforcement feature is disposed between a pair of mounting holes that is provided with the member of the second set of mounting flanges.

17. The brake rotor of claim 13 wherein a tone ring mount extends from the reinforcement feature.

18. The brake rotor of claim 17 wherein the tone ring mount has an end surface that faces in an axial direction away from the second panel, wherein the tone ring mount protrudes past the first panel such that the end surface is axially positioned further away from the second panel than the first panel.

19. A brake rotor comprising:
a first panel that extends around an axis;
a second panel that is spaced apart from the first panel and extends around the axis, wherein the first panel and the second panel cooperate to at least partially define a rotor opening;
a first set of mounting flanges that extend from the first panel into the rotor opening and are spaced apart from the second panel;
a second set of mounting flanges that extend from the second panel into the rotor opening, wherein the second set of mounting flanges is spaced apart from the first set of mounting flanges;
a reinforcement feature that extends from the first panel to a member of the first set of mounting flanges; and
a tone ring mount that extends from the reinforcement feature.

20. The brake rotor of claim 19 wherein the tone ring mount has an end surface that faces in an axial direction away from the second panel, wherein the tone ring mount protrudes past the first panel such that the end surface is axially positioned further away from the second panel than the first panel.
