Abstract

A retainer assembly may comprise: a retainer main body having a first mounting flange, a second mounting flange, a body portion, a first rib and a second rib, the body portion extending from the first mounting flange to the second mounting flange, the first rib extending from the second mounting flange towards the first mounting flange, the second rib extending from the second mounting flange towards the first mounting flange, the first rib and the second rib extending orthogonal to the body portion; and a retainer sleeve having a first slot extending from the first axial end towards the second axial end and a second slot extending from the first axial end towards the second axial end, a portion of the first rib disposed in the first slot, and a portion of the second rib disposed in the second slot.

First claim

What is claimed is:

1. A retainer assembly for use in a wheel assembly, the retainer assembly comprising:
a retainer main body having a first mounting flange, a second mounting flange, a body portion, a first rib and a second rib, the body portion extending from the first mounting flange to the second mounting flange, the first rib extending from the second mounting flange towards the first mounting flange, the second rib extending from the second mounting flange towards the first mounting flange, the first rib and the second rib extending orthogonal to the body portion;
a retainer sleeve having a flat plate extending from a first axial end to a second axial end, the retainer sleeve having a first slot extending from the first axial end towards the second axial end and a second slot extending from the first axial end towards the second axial end, a portion of the first rib disposed in the first slot, and a portion of the second rib disposed in the second slot, the retainer sleeve further comprising:
a first axially extending hook disposed on a first circumferential side of the flat plate and extending from the first axial end to the second axial end; and
a second axially extending hook disposed on a second circumferential side of the flat plate and extending from the first axial end to the second axial end, the second circumferential side opposite the first circumferential side, wherein:
the first axially extending hook defines a first groove and the second axially extending hook defines a second groove, and
the first groove and the second groove configured to receive the body portion of the retainer main body.

2. The retainer assembly of claim 1 , wherein:
the first rib and the second rib are configured to provide stiffness to the retainer assembly; and
the first slot and the second slot are sized and configured to provide substantially similar insulation properties for the retainer sleeve relative to a retainer sleeve without slots.

3. The retainer assembly of claim 1 , wherein a plurality of wing segments are coupled to the retainer main body on a radial side opposite the retainer sleeve.

4. The retainer assembly of claim 1 , wherein:
the retainer main body further comprises a first flange extending circumferentially from a first circumferential side of the body portion and a second flange extending circumferentially from a second circumferential side of the body portion, the second circumferential side opposite the first circumferential side,
the first flange is disposed in the first groove, and
the second flange is disposed in the second groove.

5. The retainer assembly of claim 1 , further comprising:
a first wing segment and a second wing segment disposed on a first circumferential side of the retainer main body, the first wing segment spaced apart axially from the second wing segment; and
a third wing segment and a fourth wing segment disposed on a second circumferential side of the retainer main body, the third wing segment spaced apart axially from the second wing segment, the second circumferential side opposite the first circumferential side.

6. A wheel assembly, comprising:
an axially inner portion of a wheel;
a torque bar coupled to an outboard end of the axially inner portion of the wheel and coupled axially to an inboard end of the axially inner portion of the wheel;
a retainer assembly disposed between the torque bar and the axially inner portion of the wheel, the retainer assembly comprising:
a retainer main body having a body portion, a first mounting flange coupled to the axially inner portion of the wheel at the outboard end, a second mounting flange coupled to the axially inner portion of the wheel at the inboard end, the body portion extending axially from the first mounting flange to the second mounting flange, a first rib extending axially from the second mounting flange towards the first mounting flange and orthogonally from a first circumferential side of the body portion, and a second rib extending axially from the second mounting flange towards the first mounting flange and orthogonally from a second circumferential side of the body portion; and
a retainer sleeve coupled to the retainer main body, the retainer sleeve having a first axial slot and a second axial slot, the first rib disposed in the first axial slot, the second rib disposed in the second axial slot, the retainer sleeve further comprising:
a flat plate extending from a first axial end to a second axial end, the first axial slot extending from the first axial end towards the second axial end and the second axial slot extending from the first axial end towards the second axial end, a portion of the first rib disposed in the first axial slot, and a portion of the second rib disposed in the second axial slot;
a first axially extending hook disposed on a first circumferential side of the flat plate and extending from the first axial end to the second axial end, and
a second axially extending hook disposed on a second circumferential side of the flat plate and extending from the first axial end to the second axial end, the second circumferential side opposite the first circumferential side.

7. The wheel assembly of claim 6 , wherein the flat plate of the retainer sleeve is disposed radially between the retainer main body and the torque bar.

8. The wheel assembly of claim 6 , wherein:
the retainer assembly is separated from a radially inner surface of the axially inner portion of the wheel by a gap, and
the retainer assembly is configured to deflect less than the gap during operation of the wheel assembly.

9. The wheel assembly of claim 6 , further comprising a first heat shield segment and a second heat shield segment, wherein the first heat shield segment is retained radially by the retainer assembly and the second heat shield segment is retained radially by the retainer assembly.

10. The wheel assembly of claim 6 , wherein:
the first rib and the second rib are configured to provide stiffness to the retainer assembly; and
the first axial slot and the second axial slot are sized and configured to provide substantially similar insulation properties for the retainer sleeve relative to a retainer sleeve without slots.

11. The wheel assembly of claim 6 , wherein a plurality of wing segments are coupled to the retainer main body on a radial side opposite the retainer sleeve.

12. The wheel assembly of claim 6 , wherein the retainer assembly further comprises:
a first wing segment and a second wing segment disposed on a first circumferential side of the retainer main body, the first wing segment spaced apart axially from the second wing segment; and
a third wing segment and a fourth wing segment disposed on a second circumferential side of the retainer main body, the third wing segment spaced apart axially from the second wing segment, the second circumferential side opposite the first circumferential side.

13. A system for retaining adjacent heat shield segments, the system comprising:
an axially inner portion of a wheel;
a first heat shield segment disposed radially inward from the axially inner portion of the wheel;
a second heat shield segment disposed radially inward form the axially inner portion of the wheel;
a retainer assembly disposed circumferentially between the first heat shield segment and the second heat shield segment, the retainer assembly, comprising:
a retainer main body including:
a first mounting flange coupled to the axially inner portion of the wheel proximate an outboard end of the axially inner portion of the wheel;
a second mounting flange coupled axially to the axially inner portion of the wheel proximate an
