Abstract

A heat shield assembly includes a first heat shield segment having a first end and a second end spaced from the first end, and a heat shield retainer including a radial extension, wherein a torque bar aperture extends through the radial extension, the torque bar aperture configured to receive a torque bar. The heat shield retainer is secured from radial movement via the radial extension.

First claim

What is claimed:

1. A heat shield assembly, comprising:
a first heat shield segment having a first end and a second end spaced from the first end; and
a heat shield retainer including a radial extension and a torque bar aperture disposed in the radial extension, the torque bar aperture configured to receive a torque bar,
wherein the heat shield retainer is radially secured via the radial extension,
the radial extension comprises a distal portion, a proximal portion, a first side portion, and a second side portion, the distal portion is disposed opposite the torque bar aperture from the proximal portion, the first side portion is disposed opposite the torque bar aperture from the second side portion, and the first and second side portions extend from the distal portion to the proximal portion;
the torque bar is configured to be received radially between the distal portion of the radial extension and the proximal portion of the radial extension such that a radially outermost surface of the torque bar is disposed radially inward from the distal portion and a radially innermost surface of the torque bar is disposed radially outward from the proximal portion of the radial extension, and
the torque bar aperture is at least partially defined by the distal portion of the radial extension, the proximal portion of the radial extension, the first side portion of the radial extension, and the second side portion of the radial extension.

2. The heat shield assembly of claim 1 , wherein the first end of the first heat shield segment includes a first hook member and the second end of the first heat shield segment includes a second hook member.

3. The heat shield assembly of claim 2 , wherein the heat shield retainer includes a first clip member configured to engage the first hook member and a second clip member.

4. The heat shield assembly of claim 3 , wherein the first hook member extends along at least a first portion of a length between an inboard end and an outboard end of the first heat shield segment.

5. The heat shield assembly of claim 4 , wherein the first clip member extends along at least the first portion of the length between the inboard end and the outboard end of the first heat shield segment.

6. The heat shield assembly of claim 5 , wherein the first hook member and the first clip member each comprise a U-shaped profile in a circumferential cross section.

7. The heat shield assembly of claim 5 , wherein the second hook member extends along at least a second portion of the length between the inboard end and the outboard end of the first heat shield segment.

8. The heat shield assembly of claim 7 , wherein the second clip member extends along at least the second portion of the length between the inboard end and the outboard end of the first heat shield segment.

9. The heat shield assembly of claim 8 , wherein the second clip member is configured to engage the second hook member of the first heat shield segment.

10. The heat shield assembly of claim 8 , further comprising a second heat shield segment and wherein the second clip member is configured to engage the second heat shield segment.

11. The heat shield assembly of claim 1 , wherein the heat shield retainer is configured for positioning proximate a radially inner surface of the first heat shield segment.

12. The heat shield assembly of claim 1 , further comprising a second heat shield segment and wherein the heat shield retainer is configured to engage the second heat shield segment.

13. A wheel assembly, comprising:
a wheel having a rim and configured to rotate about an axis;
a torque bar disposed radially inward of the rim;
a heat shield segment having a first end and a second end spaced from the first end; and
a heat shield retainer including a radial extension and a torque bar aperture disposed in the radial extension, the torque bar aperture configured to receive the torque bar,
wherein the heat shield retainer is radially secured via the radial extension,
the radial extension comprises a distal portion, a proximal portion, a first side portion, and a second side portion, the distal portion is disposed opposite the torque bar aperture from the proximal portion, the first side portion is disposed opposite the torque bar aperture from the second side portion, and the first and second side portions extend from the distal portion to the proximal portion;
the torque bar is configured to be received radially between the distal portion of the radial extension and the proximal portion of the radial extension such that a radially outermost surface of the torque bar is disposed radially inward from the distal portion and a radially innermost surface of the torque bar is disposed radially outward from the proximal portion of the radial extension, and
the torque bar aperture is at least partially defined by the distal portion of the radial extension, the proximal portion of the radial extension, the first side portion of the radial extension, and the second side portion of the radial extension.

14. The wheel assembly of claim 13 , wherein the first end of the heat shield segment includes a first hook member and the second end of the heat shield segment includes a second hook member, and
the heat shield retainer includes a first clip member configured to engage the first hook member and a second clip member.

15. The wheel assembly of claim 14 , wherein the first hook member extends along a length between an inboard end and an outboard end of the heat shield segment, and
the first clip member extends along the length between the inboard end and the outboard end of the heat shield segment.

16. The wheel assembly of claim 15 , wherein the second clip member is configured to engage the second hook member of the heat shield segment.

17. A method for assembling a heat shield assembly, comprising:
positioning a heat shield segment first end adjacent a heat shield segment second end;
sliding a heat shield retainer to engage the heat shield segment first end and the heat shield segment second end; and
positioning a torque bar to extend through a torque bar aperture disposed in a radial extension of the heat shield retainer,
wherein the radial extension comprises a distal portion, a proximal portion, a first side portion, and a second side portion, the distal portion is disposed opposite the torque bar aperture from the proximal portion, the first side portion is disposed opposite the torque bar aperture from the second side portion, and the first and second side portions extend from the distal portion to the proximal portion;
the torque bar is received radially between the distal portion of the radial extension and the proximal portion of the radial extension such that a radially outermost surface of the torque bar is disposed radially inward from the distal portion and a radially innermost surface of the torque bar is disposed radially outward from the proximal portion of the radial extension, and
the torque bar aperture is at least partially defined by the distal portion of the radial extension, the proximal portion of the radial extension, the first side portion of the radial extension, and the second side portion of the radial extension.

18. The method of claim 17 , wherein the heat shield segment first end includes a first hook member and the heat shield segment second end includes a second hook member.

19. The method of claim 18 , wherein the heat shield retainer includes a first clip member configured to engage the first hook member and a second clip member configured to en
