Abstract

A piston housing may comprise: a main annular ring defining a main bore; a torque takeout annular ring defining a torque takeout bore; a torque takeout arm extending from the main annular ring to the torque takeout annular ring and defining an aperture therethrough; and a structural rib disposed within the aperture and extending from the main annular ring to the torque takeout annular ring.

First claim

What is claimed is:

1. A piston housing, comprising:
a main annular ring defining a main bore;
a torque takeout annular ring defining a torque takeout bore;
a torque takeout arm extending from the main annular ring to the torque takeout annular ring and defining an aperture therethrough; and
a structural rib disposed within the aperture and extending from the main annular ring to the torque takeout annular ring.

2. The piston housing of claim 1 , wherein the torque takeout arm is configured to provide for transfer of torque from a brake rod coupled to the torque takeout bore to an axle coupled to the main bore.

3. The piston housing of claim 2 , wherein the structural rib is configured to dampen vibration of the piston housing during a braking event.

4. The piston housing of claim 1 , further comprising a first chamber configured to house a first piston and a second chamber configured to house a second piston, the first chamber and the second chamber being supported by the torque takeout arm.

5. The piston housing of claim 4 , wherein the torque takeout arm comprises a first leg extending from the main annular ring to the first chamber and a second leg extending from the first chamber to the torque takeout annular ring.

6. The piston housing of claim 5 , wherein the torque takeout arm further comprises a third leg extending from the main annular ring to the second chamber and a fourth leg extending from the second chamber to the torque takeout annular ring.

7. The piston housing of claim 1 , further comprising a plurality of chambers disposed radially outward of the main annular ring, each chamber in the plurality of chambers configured to house a piston therein.

8. The piston housing of claim 7 , wherein:
the plurality of chambers includes a first chamber and a second chamber; and
the torque takeout arm structurally couples the main annular ring, the first chamber, the torque takeout annular ring, and the second chamber together.

9. The piston housing of claim 1 , wherein the piston housing is a monolithic component.

10. A system for mitigating vibrations in an aircraft brake system, the system comprising:
a main annular ring defining a main bore, the main bore configured to couple to an axle of a landing gear assembly;
a torque takeout annular ring defining a torque takeout bore, the torque takeout bore configured to couple to a brake rod of the landing gear assembly;
a torque takeout arm extending from the main annular ring to the torque takeout annular ring and defining an aperture therethrough, the torque takeout arm configured to provide for transfer of torque from the brake rod to the axle; and
a structural rib disposed within the aperture and configured to dampen vibration of the system during a braking event.

11. The system of claim 10 , wherein the structural rib extends from the main annular ring to the torque takeout annular ring.

12. The system of claim 10 , wherein the torque takeout arm extends from the main annular ring to the torque takeout annular ring.

13. The system of claim 12 , further comprising a first chamber configured to house a first piston and a second chamber configured to house a second piston, the first chamber and the second chamber being supported by the torque takeout arm.

14. The system of claim 13 , wherein the torque takeout arm comprises a first leg extending from the main annular ring to the first chamber and a second leg extending from the first chamber to the torque takeout annular ring.

15. The system of claim 14 , wherein the torque takeout arm further comprises a third leg extending from the main annular ring to the second chamber and a fourth leg extending from the second chamber to the torque takeout annular ring.

16. The system of claim 10 , further comprising a plurality of chambers disposed radially outward of the main annular ring, each chamber in the plurality of chambers configured to house a piston therein.

17. The system of claim 16 , wherein:
the plurality of chambers includes a first chamber and a second chamber; and
the torque takeout arm structurally couples the main annular ring, the first chamber, the torque takeout annular ring, and the second chamber together.

18. The system of claim 10 , further comprising a piston housing, the piston housing being a monolithic component.

19. A method of retrofitting a structural rib on a piston housing assembly, the method comprising;
coupling a first end of the structural rib to a main annular ring of the piston housing assembly;
coupling a second end of the structural rib to a torque takeout annular ring of the piston housing assembly, wherein the structural rib is disposed within an aperture defined by a torque takeout arm extending from the main annular ring to the torque takeout annular ring.

20. The method of claim 19 , wherein:
the first end is coupled to the main annular ring via at least one of welding or brazing, and
the second end is coupled to the torque takeout annular ring via at least one of welding or brazing.
