Abstract

Systems and methods disclosed herein may be useful for use in a wheel assembly which includes a heat shield. In this regard heat shield for a wheel may comprise a first member; a second member positioned radially of the first member defining an annular cavity between the first member and the second member; an opening in at least one of the first member and the second member configured to provide fluidic communication between the annular cavity and an outside of the annular cavity; and a mounting feature in operable communication with the first member and the second member configured to attach the heat shield to the wheel.

First claim

What is claimed is:

1 . A heat shield for a wheel comprising:
a first member; a second member positioned radially of the first member defining an annular cavity between the first member and the second member; an opening in at least one of the first member and the second member configured to provide fluidic communication between the annular cavity and an outside of the annular cavity; and a mounting feature in operable communication with the first member and the second member configured to attach the heat shield to the wheel.

2 . The heat shield of claim 1 , wherein the first member and the second member are separated by a gap.

3 . The heat shield of claim 1 , wherein the opening is disposed on at least one of an outboard rim or an inboard rim of the heat shield.

4 . The heat shield of claim 1 , wherein the heat shield comprises a key slot tab and a key slot disposed in the key slot tab.

5 . The heat shield of claim 4 , wherein a first key slot ventilation aperture and a second key slot ventilation aperture are located between the first member of the heat shield and the key slot tab.

6 . The heat shield of claim 4 , wherein the key slot is configured to receive at least a portion of a torque bar to couple the torque bar to the heat shield.

7 . The heat shield of claim 1 , wherein at least one of the first member or the second member comprise a dimple, the dimple configured to maintain a gap between the first member and the second member.

8 . The heat shield of claim 1 , wherein the mounting feature is configured to maintain a gap between the heat shield and the wheel.

9 . The heat shield of claim 1 , wherein the heat shield comprises a single unitary member.

10 . A wheel assembly comprising:
a wheel; and a heat shield comprising:
a first member;
a second member positioned radially inward of the first member defining an annular cavity between the first member and the second member;
an opening in at least one of the first member and the second member configured to provide fluidic communication between the annular cavity and an outside of the annular cavity; and
a mounting feature in operable communication with the first member and the second member configured to attach the heat shield to the wheel.

11 . The wheel assembly of claim 10 , further comprising a torque bar located radially inward from the heat shield, the torque bar configured to be coupled to a brake stack.

12 . The wheel assembly of claim 10 , further comprising a key slot, wherein the key slot is configured to receive at least a portion of a torque bar to couple the heat shield to the torque bar.

13 . The heat shield of claim 10 , wherein the opening is disposed on at least one of an outboard rim or an inboard rim of the heat shield.

14 . The heat shield of claim 10 , wherein the heat shield comprises a key slot tab and key slot disposed in the key slot tab.

15 . The heat shield of claim 14 , wherein a first key slot ventilation aperture and a second key slot ventilation aperture are located between the first member of the heat shield and the key slot tab.

16 . The heat shield of claim 10 , wherein at least one of the first member or the second member comprise a dimple, the dimple configured to maintain a gap between the first member and the second member.

17 . The heat shield of claim 10 , wherein the mounting feature is configured to maintain a gap between the heat shield and the wheel.

18 . The heat shield of claim 10 , wherein the heat shield comprises a single unitary member.

19 . A method for assembling a wheel assembly, the method comprising:
coupling a heat shield comprising a circular geometry to a wheel via a mounting feature, the heat shield located radially inward from a wheel rim and the wheel rim circumferentially surrounding the heat shield; and coupling the heat shield to a torque bar via a key slot.

20 . The method of claim 19 , wherein the key slot is located on a first rim of the heat shield and the mounting feature is located on a second rim of the heat shield.
