Abstract

A brake shoe assembly includes the first and second sections defining a lining surface and a mounting tab. The mounting tab extends perpendicular from the lining surface and includes a series of notches allowing the formation of the lining surface into an arcuate shape. The mounting tabs are secured together such that subsequent manufacturing operations to correct distortion are not required. A brake lining is secured to the lining surface.

Claims

1. A brake shoe assembly comprising:

2. The assembly of claim 1, wherein said series of notches are v-shaped.

3. The assembly of claim 1, wherein said fastening points define corresponding openings in each mounting tab, and a fastener extends through each of said mounting tabs securing said first and second sections together.

4. The assembly of claim 1 wherein said fastening point defines a spot-weld to secure said first and second sections together.

5. The assembly of claim 1, wherein one of said mounting tabs includes a lip extending substantially perpendicular to said mounting tab and cooperating with the other of said mounting tabs to align said lining surfaces.

6. The assembly of claim 1, wherein said mounting tabs define mounting notches for mounting said brake shoe assembly within a brake assembly.

7. The assembly of claim 1, further including a joint member, said joint member fastened between said mounting tabs of said first and second sections.

8. The assembly of claim 7, wherein said joint member defines a u-shape.

9. The assembly of claim 8, wherein said joint member includes mounting tabs, and said mounting tabs including a series of notches allowing formation of said arcuate lining surface.

10. The assembly of claim 7, further including openings in said joint member corresponding with an opening defined in each of said mounting tabs, and a fastening member extending through said joint member and said mounting tab to secure said mounting tabs to said joint member.

11. The assembly of claim 7, further including a spot weld between said joint member and each of said mounting tabs to secure said mounting tabs to said joint member.

12. The assembly of claim 7, wherein said joint member defines a portion of said lining surface.

13. The assembly of claim 7, wherein said joint member includes brake shoe mounting notches for mounting of the brake shoe within a brake assembly.

14. The assembly of claim 1, further including a brake lining bonded to said lining surface.

15. The assembly of claim 1, further including a brake lining riveted to said lining surface.

16. The assembly as recited in claim 1, wherein said series of notches are uniformly shaped.

17. The assembly as recited in claim 1, wherein said series of notches are uniformly spaced along said radial inner end.

18. The assembly as recited in claim 1, wherein said mounting tabs comprise first and second distal ends and said series of notches are uniformly spaced between said first and second distal ends.
