Abstract

An apparatus for controlling the coning in a brake rotor in which the brake rotor comprises a central rotor portion, a first set of mounting members connected to the central rotor portion and an inboard friction section and a second set of mounting members connected to the central rotor portion and an outboard friction section where the inboard and outboard friction sections are connected by a plurality of air directing structures. A channel comprising the first set of mounting members, the second set of mounting member and the plurality of air directing structures is provided.

Claims (37)

1. A brake rotor, comprising:

a central rotor portion having a circular plate having a wall extending substantially horizontally therefrom;

a first set of individual mounting members connected to said wall;

a second set of individual mounting members connected to said wall;

an inboard friction section connected to said first set of mounting members; and

an outboard friction section connected to said second set of mounting members, said outboard friction section and said inboard friction section connected at least by a plurality of air directing structures;

wherein said first set of mounting members has a greater structural rigidity than said second set of mounting members and wherein said central rotor portion, said first set of mounting members, said second set of mounting members, said inboard friction section and said outboard friction section are one-piece and integrally formed.

2. The brake rotor of claim 1 , further comprising a substantially continuous channel formed by said first set of mounting members, said second set of mounting members and said plurality of air directing structures, said channel extends circumferentially about said central rotor portion.

3. The brake rotor of claim 1 , wherein mounting members of said first set of mounting members alternately extend from said central rotor portion with mounting members of said second set of mounting members.

4. The brake rotor of claim 1 , wherein adjacent mounting members of said first set of mounting members define air inlets between them and adjacent mounting members of said second set of mounting members define air inlets between them.

5. The brake rotor of claim 4 , wherein said air inlets of said first set of mounting members are at least partially axially aligned opposite said second set of mounting members.

6. A brake rotor, comprising:

a central rotor portion having a circular plate having a wall extending substantially horizontally therefrom;

a first set of individual mounting members connected to said wall;

a second set of individual mounting members connected to said wall;

an inboard friction section connected to said first set of mounting members; and

an outboard friction section connected to said second set of mounting members, said outboard friction section and said inboard friction section connected at least by a plurality of air directing structures;

wherein said first set of mounting members has a lesser structural rigidity than said second set of mounting members and wherein said central rotor portion, said first set of mounting members, said second set of mounting members, said inboard friction section and said outboard friction section are one-piece and integrally formed.

7. The brake rotor of claim 6 , further comprising a substantially continuous channel formed by said first set of mounting members, said second set of mounting members and said plurality of air directing structures, said channel extends circumferentially about said central rotor portion.

8. The brake rotor of claim 6 , wherein adjacent mounting members of said first set of mounting members define air inlets between them and adjacent mounting members of said second set of mounting members define air inlets between them.

9. The brake rotor of claim 8 , wherein said air inlets of said first set of mounting members are at least partially axially aligned opposite said second set of mounting members.

10. The brake rotor of claim 6 , wherein mounting members of said first set of mounting members alternately extend from said central rotor portion with mounting members of said second set of mounting members.

11. A brake rotor, comprising:

a central rotor portion having a circular plate having a wall extending substantially horizontally therefrom;

a first grouping of individual mounting members, having a first structural rigidity, connected to said wall;

a second grouping of individual mounting members, having a second structural rigidity different from said first structural rigidity, connected to said wall;

a first friction section connected to said first grouping of mounting members;

a second friction section connected to said second grouping of mounting members; and

a substantially continuous channel formed about said central portion of said rotor;

wherein said central rotor portion, said first set of mounting members, said second set of mounting members, said inboard friction section and said outboard friction section are one-piece and integrally formed.

12. The brake rotor of claim 11 , wherein mounting members of said first grouping of mounting members alternately extend with mounting members of said second grouping of mounting members from said central rotor portion.

13. The brake rotor of claim 11 , wherein said substantially continuous channel is formed by said first grouping of mounting members, said second grouping of mounting members and a plurality of air directing structures.

14. The brake rotor of claim 11 , wherein said first structural rigidity is greater than said second structural rigidity.

15. The brake rotor of claim 11 , wherein said first structural rigidity is less than said second structural rigidity.

16. The brake rotor of claim 11 , wherein adjacent mounting members of said first grouping define air inlets between them and adjacent mounting members of said second grouping of mounting members define air inlets between them.

17. The brake rotor of claim 11 , wherein said first friction section is an inboard friction section and said second friction section is an outboard friction section and said first structural rigidity is greater than said second structural rigidity to urge at least said outboard friction section in an outboard direction.

18. The brake rotor of claim 11 , wherein said first friction section is an inboard friction section and said second friction section is an outboard friction section and said first structural rigidity is less than said second structural rigidity and to urge at least said outboard friction section in an inboard direction.
