Abstract

A multipart torque bar is provided. Multipart torque bar may include an outer torque bar body, an inner torque bar body, a mounting hole, and a connecting end. Outer torque bar body may include a groove, wherein the inner torque bar body may removably insert within the groove. Multipart torque bars of the present disclosure can exhibit improved characteristics, such as improved vibration damping.

First claim

What is claimed is:

1. A multipart torque bar, comprising:
an outer torque bar body having a first end and a second end, a top surface and a bottom surface, and a groove, wherein the groove defines an opening on the outer torque bar body beginning on the first end of the top surface and extending in an axial direction proximate the second end; and
an inner torque bar body having a first end, a second end, a top surface, and a bottom surface, wherein the inner torque bar body is configured to be removably inserted within the groove of the outer torque bar body.

2. The multipart torque bar of claim 1 , further comprising a mounting hole located on the top surface of the inner torque bar body proximate the first end of the inner torque bar body.

3. The multipart torque bar of claim 1 , further comprising a connecting end located on the second end of the outer torque bar body.

4. The multipart torque bar of claim 3 , wherein the connecting end is a pin end connector.

5. The multipart torque bar of claim 1 , wherein the groove is in a shape of a box joint.

6. The multipart torque bar of claim 1 , wherein the groove is in a shape of a dove-tail joint.

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

8. A wheel and brake assembly, comprising:
a wheel having a radially inner surface and an at least one connecting hole; and
a multipart torque bar comprising:
an outer torque bar body having a first end and a second end, a top surface and a bottom surface, and a groove, wherein the groove defines an opening on the outer torque bar body beginning on the first end of the top surface and extending in an axial direction proximate the second end;
an inner torque bar body having a first end and a second end and a top surface and a bottom surface, wherein the inner torque bar body is configured to be removably inserted within the groove of the outer torque bar body;
a mounting hole located on the top surface of the inner torque bar body by the first end of the inner torque bar body; and
a connecting end located on the second end of the outer torque bar body;

wherein the multipart torque bar is coupled to the radially inner surface at the mounting hole, and the connecting end is coupled to the at least one connecting hole.

9. The wheel and brake assembly of claim 8 , wherein the groove is in a shape of a box joint.

10. The wheel and brake assembly of claim 8 , wherein the groove is in a shape of a dove-tail joint.

11. The wheel and brake assembly of claim 10 , wherein the inner torque bar body comprises a dove-tail shape.

12. The wheel and brake assembly of claim 8 , wherein the multipart torque bar is coated with a tungsten carbide cobalt coating.

13. The wheel and brake assembly of claim 8 , wherein the connecting end is a pin end connector.

14. The wheel and brake assembly of claim 8 , wherein the multipart torque bar is formed by an investment casting process.

15. A method, comprising:
inserting an inner torque bar body into an outer torque bar body to form a multipart torque bar, wherein the outer torque bar body comprises a first end and a second end, a top surface and a bottom surface, and a groove, wherein the groove defines an opening on the outer torque bar body beginning on the first end of the top surface and extending in an axial direction proximate the second end, and wherein the inner torque bar body is configured to removably insert within the groove of the outer torque bar body;
mounting the multipart torque bar onto a wheel and brake assembly, wherein the wheel and brake assembly comprises a wheel having a radially inner surface and a connecting hole; and
coupling the multipart torque bar to the wheel and brake assembly.

16. The method of claim 15 , wherein the outer torque bar body further comprises a connecting end located at the second end, and the inner torque bar body further comprises a mounting hole located on the top surface of the inner torque bar body proximate the first end.

17. The method of claim 16 , wherein coupling the multipart torque bar to the wheel and brake assembly comprises coupling the connecting end to the wheel and coupling the multipart torque bar to the radially inner surface.

18. The method of claim 15 , wherein coupling the multipart 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.

19. The method of claim 15 , wherein the groove is in a shape of a box joint.

20. The method of claim 15 , wherein the groove is in a shape of a dove-tail joint.
