HEAT SHIELD ASSEMBLY

Abstract

A heat shield assembly for a braked aircraft wheel is provided. The heat sheild assembly includes a heat shield and at least one spacer having both a main body projecting from an outwardly-facing surface of the heat shield and a clamping element of generally cylindrical shape projecting from the body and passing perpendicularly through an opening in the heat shield. The clamping element can include an enlarged free end so as to co-operate with the body to form an annular groove engaged with the opening in the heat shield.

Description

Claims

1. A heat shield assembly for a braked aircraft wheel, the heat shield assembly comprising: a heat shield; andat least one spacer comprising: a main body projecting from an outwardly-facing surface of the heat shield; anda clamping element of generally cylindrical shape projecting from the body and passing perpendicularly through an opening in the heat shield, the clamping element having an enlarged free end so as to co-operate with the body to form an annular groove engaged with the peripheral edge of the opening in the heat shield,wherein the opening has the shape of a drop of water.

2. The heat shield assembly of claim 1, wherein the peripheral edge of the opening includes both a larger-diameter circular portion and a smaller-diameter circular portion the portions being connected together by two identical rectilinear portions.

3. The heat shield assembly of claim 2, wherein the opening has a length that is substantially equal to a diameter of the enlarged free end of the clamping element.

4. The heat shield assembly of claim 2, wherein the larger-diameter circular portion of the opening has a diameter substantially equal to a diameter of the bottom of the groove in the spacer.

5. The heat shield assembly of claim 1, wherein the smaller-diameter circular portion of the opening hasa diameter greater than or equal to a thickness of the enlarged free end of the clamping element.

6. The heat shield assembly of claim 1, wherein the groove has a thickness greater than or equal to a thickness of the heat shield.

7. The heat shield assembly of claim 1, wherein the body of the spacer further comprises a cylindrical portion having one end from which the clamping element projects along the axis of the cylindrical portion and an opposite end that is free and covered by a spherical cap.

8. The heat shield assembly of claim 1, wherein the heat shield includes two openings, and the spacer includes two clamping elements, the body of the spacer being elongate in shape and having two ends, each of which ends is provided with a respective one of the clamping elements cooperating with a respective one of the openings in the heat shield.

9. The heat shield assembly of claim 8, wherein the openings in the heat shield present a common longitudinal axis of symmetry and the openings point towards each other.
