Abstract

A torque tube for a brake assembly, the torque tube includes a first tube segment, a second tube segment coupled to the first tube segment at a concatenation location, and a foot portion extending radially from the concatenation location, wherein said torque tube undergoes a change of thickness resulting in said first tube segment having a first thickness different than a second thickness of said second tube segment.

First claim

What is claimed is:

1. A torque tube for a brake assembly, the torque tube comprising:
a first tube segment having a first end, the first tube segment including a first outer diameter extending from the first end to a concatenation location;
a second tube segment coupled to said first tube segment at the concatenation location, the second tube segment having a conical back leg portion, the second tube segment including a second outer diameter extending from the concatenation location to the conical back leg portion; and
a foot extending radially from said concatenation location,
wherein said torque tube undergoes a change of thickness resulting in said first tube segment having a first thickness different than a second thickness of said second tube segment,
wherein said second thickness is greater than said first thickness,
wherein the first outer diameter and the second outer diameter are equal, and
wherein said second thickness extends from the concatenation location to the conical back leg portion.

2. The torque tube of claim 1 , wherein said change of thickness is an abrupt change of thickness.

3. The torque tube of claim 1 , wherein said first thickness is 0.174 inches and said second thickness is 0.254 inches.

4. The torque tube of claim 1 , wherein said change of thickness occurs starting at a first transition location and ends at a second transition location.

5. The torque tube of claim 1 , wherein said first tube segment is an inboard barrel and said second tube segment is an outboard barrel.

6. The torque tube of claim 1 , wherein said first tube segment and said second tube segment combine to form a barrel.

7. The torque tube of claim 1 , wherein the first thickness and the second thickness are along a single plane taken from a longitudinal cross-section from the torque tube.

8. A method of mitigating damage in a brake assembly, comprising:
thickening a first tube segment to a first thickness, the first tube segment having a first end and a first outer diameter;
thickening a second tube segment to a second thickness, the second tube segment having a second outer diameter;
coupling a back conical portion to the second tube segment;
combining said first tube segment and said second tube segment at a concatenation location to form a torque tube and
extending a foot radially from said concatenation location,
wherein the first outer diameter extends from the first end of the first tube segment to the concatenation location,
wherein the second outer diameter extends from the concatenation location to the back conical portion,
wherein the first outer diameter and the second outer diameter are equal, and
wherein the second thickness is greater than the first thickness.

9. The method of claim 8 , wherein a change of thickness occurs at said concatenation location.

10. The method of claim 9 , wherein said change of thickness is an abrupt change of thickness.

11. The method of claim 9 , wherein said change of thickness is a gradual change of thickness.

12. The method of claim 9 , wherein said change of thickness occurs at a specific point.

13. The method of claim 9 , wherein said change of thickness occurs within a range starting at a first transition location and a second transition location.

14. The method of claim 8 , wherein the first thickness and the second thickness are along a single plane taken from a longitudinal cross-section from the torque tube.

15. A torque tube for a brake assembly, the torque tube comprising:
a first tube segment having a first transition location;
a second tube segment coupled to said first tube segment, the second tube segment having a second transition location;
a concatenation location disposed between the first tube segment and the second tube segment;
a conical back leg portion coupled to the second tube segment; and
a foot extending radially from the concatenation location, wherein a change of thickness occurs at the first transition location and increases gradually to the second transition location, wherein said first tube segment is at a first thickness forward of the first transition location different from a second thickness aft of the second transition location of said second tube segment, wherein the first transition location is forward of the concatenation location, and wherein the second transition location is aft of the concatenation location.

16. The torque tube of claim 15 , wherein a thickness rate of change between the first transition location and the second transition location is between 1% and 8%.

17. The torque tube of claim 15 , wherein the first thickness and the second thickness are along a single plane taken from a longitudinal cross-section from the torque tube.

18. A torque tube for a brake assembly, the torque tube comprising:
a first tube segment having a first end, the first tube segment including a first outer diameter extending from the first end to a concatenation location; and
a second tube segment coupled to said first tube segment at the concatenation location, the second tube segment having a conical back leg portion, the second tube segment including a second outer diameter extending from the concatenation location to the conical back leg portion,
wherein said torque tube undergoes a change of thickness resulting in said first tube segment having a first thickness different than a second thickness of said second tube segment,
wherein said second thickness is greater than said first thickness,
wherein the first outer diameter and the second outer diameter are equal,
wherein said second thickness extends from the concatenation location to the conical back leg portion, and
wherein said change of thickness is an abrupt change of thickness.

19. A method of mitigating damage in a brake assembly, comprising:
thickening a first tube segment to a first thickness, the first tube segment having a first end and a first outer diameter;
thickening a second tube segment to a second thickness, the second tube segment having a second outer diameter;
coupling a back conical portion to the second tube segment; and
combining said first tube segment and said second tube segment at a concatenation location to form a torque tube,
wherein the first outer diameter extends from the first end of the first tube segment to the concatenation location,
wherein the second outer diameter extends from the concatenation location to the back conical portion,
wherein the first outer diameter and the second outer diameter are equal,
wherein the second thickness is greater than the first thickness,
wherein a change of thickness occurs at said concatenation location, and
wherein said change of thickness is an abrupt change of thickness.
