## Abstract

A wheel assembly includes a wheel portion comprises a web having an inboard surface. The web may define a torque bar retention slot that extends from the inboard surface of the web. The wheel assembly may also include a bushing disposed in the torque bar retention slot, wherein the bushing comprises an open end and a closed end. Still further, the wheel assembly may include a torque bar coupled to the wheel, and the torque bar may include a boss extending into the bushing through the open end of the bushing such that the boss of the torque bar is at least partially disposed within the torque bar retention slot of the wheel portion.

## Claims

### Claim 1

A wheel assembly comprising:
an inboard wheel portion comprising a web having an inboard surface and a first mating surface, wherein a torque bar retention slot is defined in the web and extends completely through the web from the inboard surface to the first mating surface;
an outboard wheel portion comprising an outboard web having a second mating surface, wherein the first mating surface and the second mating surface are disposed adjacent each other and form a joining interface between the inboard wheel portion and the outboard wheel portion;
a bushing disposed in the torque bar retention slot, wherein the bushing comprises an open end and a closed end; and
a torque bar coupled to the wheel portion, the torque bar comprising a boss extending into the bushing through the open end of the bushing such that the boss of the torque bar is at least partially disposed within the torque bar retention slot of the wheel portion.

### Claim 2 (depends on 1)

The wheel assembly of claim 1, further comprising a plurality of bolts extending through the inboard web and the outboard web to retain together the inboard wheel portion and the outboard wheel portion, wherein the torque bar retention slot is substantially parallel to the plurality of bolts.

### Claim 3 (depends on 1)

The wheel assembly of claim 1, wherein the open end of the bushing comprises a flange that engages the inboard surface of the web of the wheel portion.

### Claim 4 (depends on 1)

The wheel assembly of claim 1, wherein the closed end of the bushing is tapered.

### Claim 5 (depends on 1)

The wheel assembly of claim 1, wherein the bushing has an interference fit within the torque bar retention slot and the boss of the torque bar is loosely fit within the bushing.

### Claim 6

A method of assembling a wheel assembly, the method comprising:
inserting a bushing into a torque bar retention slot of a web of a wheel portion, wherein the torque bar retention slot is a pass-through hole that extends completely through the web of the wheel portion, wherein the bushing comprises a closed end and an open end; and
inserting a boss of a torque bar into the bushing through the open end.

### Claim 7 (depends on 6)

The method of claim 6, wherein inserting the boss of the torque bar into the bushing is performed after inserting the bushing into the torque bar retention slot.

### Claim 8 (depends on 6)

The method of claim 6, further comprising coupling the torque bar to an inboard flange of the wheel portion.

### Claim 9 (depends on 8)

The method of claim 8, wherein coupling the torque bar to the inboard flange of the wheel portion is performed after inserting the boss of the torque bar into the bushing.
