Abstract

A torque barrel for use with a brake system may comprise a torque barrel having a cylindrical structure including an inner surface, an outer surface, a first opening at a first end, and a second opening at an opposing second end; and a longitudinal hole disposed through the outer surface of the barrel between a first spline of the plurality of splines and a second spline of the plurality of splines.

First claim

What is claimed is:

1. A torque barrel for use with a brake system, comprising:
a torque barrel body having a cylindrical structure including an inner surface, an outer surface, a first opening at a first end, and a second opening at an opposing second end; and
a longitudinal hole disposed through the outer surface of the torque barrel body between a first spline of a plurality of splines and a second spline of the plurality of splines, wherein the longitudinal hole has a first end, an opposing second end, and a center portion, the center portion having a first width and the first end having a second width that is greater than the first width.

2. The torque barrel of claim 1 , wherein the longitudinal hole has a first end having a tear drop shape.

3. The torque barrel of claim 2 , wherein the first end has a length and a width, the length to width ratio being about 1.5:1.

4. The torque barrel of claim 1 , wherein the longitudinal hole has a width in a circumferential direction and a length in an axial direction and the width of the longitudinal hole at a first end is greater than the width at the second end.

5. The torque barrel of claim 1 , further comprising:
a second longitudinal hole disposed between the longitudinal hole and the first end of the torque barrel body.

6. The torque barrel of claim 5 , wherein the second longitudinal hole is axially in line with and aft of the longitudinal hole.

7. The torque barrel of claim 6 , wherein the longitudinal hole has a first length and the second longitudinal hole has a second length that is less than the first length.

8. The torque barrel of claim 1 , further comprising:
a plurality of longitudinal holes disposed through the outer surface of the torque barrel body, the plurality of longitudinal holes being disposed symmetrically around an outer circumference of the torque barrel body.

9. The torque barrel of claim 1 , wherein the plurality of splines is disposed around a circumference of the torque barrel body and each spline of the plurality of splines extends from the first end to the second end along the outer surface of the torque barrel body.

10. The torque barrel of claim 1 , further comprising:
a torque plate coupled to the second end of the torque barrel body, the torque plate including a plurality of back legs, each back leg of the plurality of back legs having a hole disposed therein.

11. A brake assembly attached to a wheel, comprising:
a torque barrel having an outer surface and an axial length;
an elongated hole disposed in the outer surface along the axial length, the elongated hole having a rounded first end having a first width and an opposing rounded second end, wherein the elongated hole has a center portion extending between the first end and the second end, the center portion having a second width that is less than the first width;
a heat sink disposed around the torque barrel; and
a plurality of stator disks mounted to the torque barrel.

12. The brake assembly of claim 11 , wherein the rounded first end has a length that is greater than the first width.

13. The brake assembly of claim 11 , wherein the elongated hole is a first elongated hole, the brake assembly further comprising:
a second elongated hole disposed in the outer surface of the torque barrel, the second elongated hole being disposed along the axial length of the torque barrel and circumferentially adjacent the first elongated hole.

14. The brake assembly of claim 13 , wherein the second elongated hole is longer than the first elongated hole.

15. The brake assembly of claim 11 , further comprising:
a spline disposed along the outer surface of the torque barrel adjacent the elongated hole.

16. The brake assembly of claim 11 , wherein the elongated hole is a first elongated hole, the brake assembly further comprising:
a second elongated hole disposed axially in line with the first elongated hole.

17. The brake assembly of claim 11 , wherein the elongated hole is a first elongated hole, the brake assembly further comprising:
a second elongated hole disposed in the outer surface of the torque barrel, the second elongated hole having a first end and a second end, the first end of the second elongated being axially offset from the first elongated hole.

18. A method of forming a torque barrel, comprising:
forming a barrel having an outer surface having a first end and an opposing second end; and
forming an elongated hole in the outer surface of the barrel, the elongated hole having a first end, an opposing second end, and a center portion, the elongated hole extending between the first end and the second end, the center portion having a first width and the first end having a second width that is greater than the first width.
