## Abstract

A torque tube for a brake assembly may include a tube portion having a first centerline axis, a conical back-leg portion extending from the tube portion in a radially outward angled orientation relative to the first centerline axis, and a lip portion disposed at a radially outward end of the conical back-leg portion. The lip portion may have added structural material to improve the structural properties of the torque tube to prevent or mitigate damage that would otherwise be caused by friction-induced vibrations.

## Claims

### Claim 1

A torque tube for a brake assembly, the torque tube comprising:
a tube portion having a first centerline axis;
a conical back-leg portion extending from the tube portion in a radially outward angled orientation relative to the first centerline axis, the conical back-leg portion comprising a radially inward surface; and
a lip portion disposed at a radially outward end of the conical back-leg portion, the lip portion having a proximal surface, a distal surface, and a radially outward surface, wherein the lip portion defines a hole extending from the proximal surface to the distal surface that is configured to receive a fastener for mounting a brake stack of the brake assembly, wherein the hole has a second centerline axis that is substantially parallel to the first centerline axis, wherein the radially inward surface of the conical back-leg portion continuously extends, at the radially outward angled orientation, to the radially outward surface of the lip portion such that the radially inward surface of the conical back-leg portion comprises the distal surface of the lip portion;
wherein a distal end of the hole is defined by the distal surface of the lip portion such that the distal end of the hole comprises the radially outward angled orientation.

### Claim 2 (depends on 1)

The torque tube of claim 1, wherein the radially inward surface of the conical back-leg portion is parallel with the distal surface of the lip portion.

### Claim 3 (depends on 1)

The torque tube of claim 1, wherein a first angle between the first centerline axis and the radially inward surface of the conical back-leg portion has the same magnitude as a second angle between the radially outward surface of the lip portion and the distal surface of the lip portion.

### Claim 4 (depends on 1)

The torque tube of claim 1, wherein the radially outward surface of the lip portion is parallel with the second centerline axis.

### Claim 5 (depends on 1)

The torque tube of claim 1, wherein the radially outward surface of the lip portion is directly adjacent the distal surface.

### Claim 6 (depends on 1)

The torque tube of claim 1, wherein the radially outward surface is a radially outermost section of the lip portion.
