Abstract

A brake assembly having a brake carrier, a housing, and a bridge. The brake carrier may support at least one brake pad assembly. The housing may be disposed on the brake carrier. The bridge may be fixedly disposed on the housing. The bridge may extend over the brake pad assembly.

First claim

What is claimed is:

1. A brake assembly comprising:
a brake carrier that supports first and second brake pad assemblies;
first and second brake pad springs disposed on the first and second brake pad assemblies, respectively;
a housing disposed on the brake carrier, wherein the housing receives an actuator for actuating the first and second brake pad assemblies; and
a bridge that is fixedly disposed on the housing, the bridge including:
a first side surface that faces toward the brake carrier;
a second side surface that faces toward the brake carrier and is disposed opposite the first side surface;
an inner surface that extends from the first side surface to the second side surface and extends over the first and second brake pad assemblies, wherein the first and second brake pad springs engage the inner surface; and
a support bracket that extends from the inner surface, wherein the support bracket has an inner wall that extends from the inner surface and engages the second brake pad assembly, an outer wall that extends from the inner surface and is spaced apart from the inner wall, and a connecting wall that extends from an end of the inner wall that is disposed opposite the inner surface to an end of the outer wall.

2. The brake assembly of claim 1 wherein the inner surface extends continuously along an arc from the first side surface to the second side surface such that no openings are provided in the bridge between the first side surface and the second side surface in a center region that extends over the first and second brake pad assemblies.

3. The brake assembly of claim 1 wherein the bridge further comprises an abutment surface disposed proximate the housing and an end surface disposed opposite the abutment surface, wherein the inner surface extends from the abutment surface to the end surface.

4. The brake assembly of claim 3 wherein the first side surface and the second side surface extend from the abutment surface to the end surface.

5. The brake assembly of claim 1 wherein the bridge further comprises a mounting stud that extends from the bridge and couples the bridge to the housing.

6. The brake assembly of claim 5 further comprising a mounting stud flange that is disposed on the inner surface, wherein the mounting stud is disposed on the mounting stud flange and extends through a hole in the housing.

7. The brake assembly of claim 6 wherein the mounting stud is spaced apart from and does not engage the inner surface.

8. A brake assembly comprising:
a housing that receives an actuator that actuates a brake pad assembly;
a bridge that is fixedly disposed on the housing, the bridge including:
an abutment surface disposed on the housing;
an end surface disposed opposite the abutment surface;
a first side surface that extends from the abutment surface to the end surface;
a second side surface that extends from the abutment surface to the end surface and is disposed opposite the first side surface;
an inner surface that extends from the abutment surface to the end surface and from the first side surface to the second side surface; and
a support bracket that extends from the inner surface, wherein the support bracket has an inner wall that extends from the inner surface and engages the brake pad assembly, an outer wall that is spaced apart from the inner wall and extends from the inner surface, and a connecting wall that extends from an end of the inner wall that is disposed opposite the inner surface to an end of the outer wall.

9. The brake assembly of claim 8 wherein the inner wall faces toward the housing and the support bracket extends from the inner surface and is spaced apart from the first side surface and the second side surface.

10. The brake assembly of claim 9 wherein the support bracket has a first reinforcement flange that extends from a first end of the inner wall toward the first side surface, wherein the first reinforcement flange extends toward the end surface such that the first reinforcement flange does not engage the brake pad assembly.

11. The brake assembly of claim 10 wherein the first reinforcement flange extends from the inner surface.

12. The brake assembly of claim 10 wherein the support bracket has a second reinforcement flange that extends from a second end of the inner wall that is disposed opposite the first end toward the second side surface, wherein the second reinforcement flange extends toward the end surface such that the second reinforcement flange does not engage the brake pad assembly.

13. The brake assembly of claim 12 wherein the second reinforcement flange extends from the inner surface.

14. The brake assembly of claim 8 wherein the bridge further comprises a mounting stud that extends from the bridge and couples the bridge to the housing.

15. The brake assembly of claim 8 wherein the connecting wall extends along an arc.

16. The brake assembly of claim 8 further comprising a brake pad spring that is disposed on the brake pad assembly and engages the inner surface.

17. The brake assembly of claim 8 wherein the outer wall is disposed between the inner wall and the end surface.

18. The brake assembly of claim 8 wherein the connecting wall is disposed further from the inner surface than the inner wall and the outer wall.

19. The brake assembly of claim 10 wherein the first reinforcement flange is disposed further from the housing than the connecting wall.

20. The brake assembly of claim 8 wherein the outer wall is disposed adjacent to the end surface of the bridge.
