Abstract

A retainer for connecting two panels of a heat shield assembly, the retainer comprising: a central elongate panel having a length l and a width w, a top end, a bottom end and first and second long sides extending from the top end to the bottom end; a first side panel extending along the first long side of the central elongate panel and a second side panel extending along the second long side of the central elongate panel; and wherein the central elongate panel is corrugated, with corrugations running along the length of the central elongate panel from the top end to the bottom end.

First claim

What is claimed is:

1 . A retainer for connecting two panels of a heat shield assembly, the retainer comprising: a central elongate panel having a length l and a width w, a top end, a bottom end and first and second long sides extending from the top end to the bottom end; a first side panel extending along the first long side of the central elongate panel and a second side panel extending along the second long side of the central elongate panel; wherein the central elongate panel is corrugated, with corrugations running along the length of the central elongate panel from the top end to the bottom end, and wherein the retainer is formed of a top section, a middle section and a bottom section, the top section welded to one end of the middle section and the bottom section welded to the other end of the middle section.

2 . The retainer of claim 1 , further comprising a tab extending from the top end.

3 . The retainer of claim 2 , further comprising a fastening hole formed in the tab.

4 . The retainer of claim 1 , further comprising a foot at the bottom end.

5 . The retainer of claim 4 , further comprising a locating hole in the foot.

6 . The retainer of claim 1 , the central panel and the first and second side panels being formed from a single piece of sheet metal.

7 . A heat shield assembly for a wheel assembly, comprising a plurality of arcuate heat shield panels arranged to be connected together to form a heat shield to be attached to an interior of a wheel, and the retainer as claimed in claim 1 , for attaching adjacent panels.

8 . The heat shield assembly as claimed in claim 7 , wherein one or more retainers is provided between each pair of adjacent panels.

9 . The heat shield assembly of claim 7 , wherein each panel comprises two heat shield panel layers arranged radially adjacent each other and wherein the retainer prevents relative movement of the layers.

10 . A wheel assembly comprising a wheel rim having a radially inner surface and a radially outer surface, and the heat shield assembly as claimed in claim 7 , attached to and having a radially outer surface and a radially inner surface, the radially outer surface of the heat shield assembly radially spaced from the radially inner surface of the wheel rim.

11 . The wheel assembly of claim 10 , further comprising a plurality of torque bars arranged around the radially inner surface of the heat shield, a torque bar positioned along the central elongate panel of each retainer.

12 . The wheel assembly of claim 10 being the wheel assembly for a landing gear of an aircraft.
