Abstract

A stiffened torque bar is provided. Stiffened torque bar may include a torque bar body, a mounting hole, and a bolt strap. Stiffened torque bar may also comprise a first sleeve and a second sleeve. Stiffened torque bars of the present disclosure can exhibit improved desired characteristics, such as improved stiffness and vibration damping in order to enhance dynamic stability in the stiffened torque bar.

First claim

What is claimed is:

1. A stiffened torque bar, comprising:
a torque bar body having a first end and a second end;
a bolt strap having a front surface and a back surface and a first aperture and a second aperture, wherein the bolt strap is perpendicular to the torque bar body, and wherein the bolt strap meets the torque bar body between the first aperture and the second aperture; and
a mounting hole located in the torque bar body by the first end.

2. The stiffened torque bar of claim 1 , further comprising a first sleeve defining the first aperture and protruding from the first aperture in a direction axially away from the torque bar body, and a second sleeve defining the second aperture and protruding from the second aperture in a direction axially away from the torque bar body.

3. The stiffened torque bar of claim 2 , wherein the first sleeve and the second sleeve are configured to operatively fit within a tie bolt hole of a wheel.

4. The stiffened torque bar of claim 1 , wherein the first aperture and the second aperture are configured to receive a tie bolt.

5. The stiffened torque bar of claim 1 , wherein the stiffened torque bar is formed by an additive manufacturing process.

6. The stiffened torque bar of claim 1 , wherein the stiffened torque bar is formed by an investment casting process.

7. The stiffened torque bar of claim 1 , wherein the stiffened torque bar is coated with a tungsten carbine cobalt coating.

8. A wheel and brake assembly, comprising:
a wheel having a radially inner surface and an at least one tie bolt hole; and
an at least one stiffened torque bar comprising:
a torque bar body having a first end and a second end;
a bolt strap having a front surface and a back surface and a first aperture and a second aperture, wherein the front surface of the bolt strap is perpendicularly coupled between the first aperture and the second aperture to the second end; and
a mounting hole located in the torque bar body by the first end;

wherein the at least one stiffened torque bar is coupled to the radially inner surface at the mounting hole, and the bolt strap is coupled to the at least one tie bolt hole.

9. The wheel and brake assembly of claim 8 , wherein the at least one stiffened torque bar further comprises a first sleeve defining the first aperture and protruding from the first aperture in a direction axially away from the at least one torque bar body, and a second sleeve defining the second aperture and protruding from the second aperture in a direction axially away from the at least one torque bar body.

10. The wheel and brake assembly of claim 9 , wherein the first sleeve and the second sleeve are configured to operatively fit within the at least one tie bolt hole of the wheel.

11. The wheel and brake assembly of claim 8 , wherein the bolt strap is coupled to the wheel by inserting a tie bolt through the first aperture and a tie bolt through the second aperture, and securing the tie bolts into the at least one tie bolt hole.

12. The wheel and brake assembly of claim 8 , wherein the at least one stiffened torque bar is formed by an additive manufacturing process.

13. The wheel and brake assembly of claim 8 , wherein the at least one stiffened torque bar is formed by an investment casting process.

14. The wheel and brake assembly of claim 8 , wherein the at least one stiffened torque bar is coated with a tungsten carbine cobalt coating.

15. A method, comprising:
mounting a stiffened torque bar onto a wheel and brake assembly, wherein the stiffened torque bar comprises: a torque bar body having a first end and a second end; a bolt strap having a front surface and a back surface and a first aperture and a second aperture, wherein the front surface of the bolt strap is perpendicularly coupled between the first aperture and the second aperture to the second end; and a mounting hole located in the torque bar body by the first end; and the wheel and brake assembly comprises a wheel having a radially inner surface and an at least one tie bolt hole;
coupling the bolt strap to the wheel; and
coupling the stiffened torque bar to the radially inner surface.

16. The method of claim 15 , wherein coupling the bolt strap to the wheel comprises inserting a tie bolt into the first aperture and a tie bolt into the second aperture, and securing the tie bolts into the at least one tie bolt hole.

17. The method of claim 15 , wherein coupling the stiffened torque bar to the radially inner surface comprises inserting a bolt through the mounting hole and securing the bolt into a bolt hole in the radially inner surface.

18. The method of claim 15 , wherein the stiffened torque bar further comprises a first sleeve defining the first aperture and protruding from the first aperture in a direction axially away from the torque bar body, and a second sleeve defining the second aperture and protruding from the second aperture in a direction axially away from the torque bar body.

19. The method of claim 18 , further comprising inserting the first sleeve and the second sleeve into the at least one tie bolt hole of the wheel prior to coupling the bolt strap to the wheel.

20. The method of claim 19 , wherein coupling the bolt strap to the wheel comprises inserting a tie bolt into the first aperture and through the first sleeve, and inserting a tie bolt into the second aperture and through the second sleeve, and securing the tie bolts into the at least one tie bolt hole.
