Abstract

A heat shield assembly for a braked aircraft wheel is provided. The heat shield 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.

Claims (13)

1 . A heat shield assembly for a braked aircraft wheel, the heat shield assembly comprising:

a heat shield; and

at least one spacer comprising:

a main body projecting from an outwardly-facing surface of the heat shield; and

a clamping element of generally cylindrical shape projecting from the main 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 main body to form an annular groove engaged with a peripheral edge of the opening in the heat shield,

wherein the opening has the shape of a drop of water, the peripheral edge of the opening includes a larger-diameter circular portion, a smaller-diameter circular portion, and two identical rectilinear portions connecting the larger-diameter circular portion to the smaller-diameter circular portion.

2 . The heat shield assembly of claim 1 , wherein the opening has a length that is substantially equal to a diameter of the enlarged free end of the clamping element.

3 . The heat shield assembly of claim 1 , 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.

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

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

6 . The heat shield assembly of claim 1 , wherein the main 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.

7 . The heat shield assembly of claim 1 , wherein the heat shield includes two openings, and the spacer includes two clamping elements, the main 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.

8 . The heat shield assembly of claim 7 , wherein the openings in the heat shield present a common longitudinal axis of symmetry and the openings point towards each other.
