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 include 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;
a key slot tab; and
a key slot disposed in the key slot tab,
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.

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 key slot is configured to receive at least a portion of a torque bar to couple the torque bar to the heat shield.

5. 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.

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

7. The heat shield of claim 1 , wherein the first member comprises a first single unitary member and the second member comprises a second single unitary member, wherein the first member and the second member collectively form a circle.

8. 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;
a mounting feature in operable communication with the first member and the second member configured to attach the heat shield to the wheel;
a key slot tab; and
a key slot disposed in the key slot tab,
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.

9. The wheel assembly of claim 8 , further comprising a torque bar located radially inward from the heat shield, the torque bar configured to be coupled to a brake stack.

10. The wheel assembly of claim 8 , 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.

11. The heat shield of claim 8 , wherein the opening is disposed on at least one of an outboard rim or an inboard rim of the heat shield.

12. The heat shield of claim 8 , 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.

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

14. The heat shield of claim 8 , wherein the first member comprises a first single unitary member and the second member comprises a second single unitary member, wherein the first member and the second member collectively form a circle.

15. A method for assembling a wheel assembly, the method comprising:
coupling a heat shield comprising a circular geometry to a wheel with a mounting feature, the heat shield located radially inward from a wheel rim and the wheel rim circumferentially surrounding the heat shield; and
coupling a torque bar to a key slot disposed in a key slot tab of the heat shield,
wherein a first key slot ventilation aperture and a second key slot ventilation aperture are located between a first member of the heat shield and the key slot tab.

16. The method of claim 15 , 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.
