Abstract

Various embodiments provide a stabilizing transom. Various embodiments provide a vehicle truck such as a railroad car truck including a first side frame, a second side frame, a bolster, and a stabilizing transom connected to the first side frame and the second side frame and configured to reduce, inhibit, minimize, and/or prevent truck hunting and warping.

First claim

The invention claimed is:

1. A railroad car truck comprising:
a first side frame;
a second side frame;
a bolster; and
a transom including:
a panel assembly; and
a first connector assembly connecting the panel assembly to the first side frame,
a second connector assembly connecting the panel assembly to the first side frame,
a third connector assembly connecting the panel assembly to the second side frame,
a fourth connector assembly connecting the panel assembly to the second side frame,
wherein each connector assembly includes:
a top connection plate,
a spacer connection plate, and
at least one bottom connection plate.

2. The railroad car truck of claim 1 , wherein the connection plates of each of the connector assemblies are made from steel.

3. The railroad car truck of claim 2 , wherein the connection plates of each of the first and second connector assemblies are welded to the first side frame and the connection plates of each of the third and fourth connector assemblies are welded to the second side frame.

4. The railroad car truck of claim 1 , wherein each connector assembly includes a first bottom connection plate and a second bottom support plate.

5. The railroad car truck of claim 4 , wherein for each connector assembly, the top connection plate, the spacer connection plate, the first bottom connection plate, and the second bottom support plate have decreasing widths along their respective connection edges.

6. The railroad car truck of claim 4 , wherein for each connector assembly, the top connection plate, the spacer connection plate, the first bottom connection plate, and the second bottom support plate are vertically aligned.

7. The railroad car truck of claim 1 , wherein for each connector assembly, the top connection plate, the spacer connection plate, and the at least one bottom connection plate are positioned to form a space between the top connection plate and the at least one bottom connection plate.

8. The railroad car truck of claim 1 , wherein the panel assembly includes a first transom plate, a second transom plate, and a third transom plate.

9. The railroad car truck of claim 8 , wherein the first transom plate is connected to each of the first, second, third, and fourth connector assemblies by a plurality of fasteners.

10. The railroad car truck of claim 8 , wherein the first transom plate defines tapered cutouts extending from opposite ends of the first transom plate.

11. The railroad car truck of claim 8 , wherein the second transom plate is connected to the first side frame by the first connector assembly and is connected to the second side frame by the third connector assembly.

12. The railroad car truck of claim 11 , wherein the third transom plate is connected to the first side frame by the second connector assembly and is connected to the second side frame by the fourth connector assembly.

13. The railroad car truck of claim 1 , wherein the transom is configured to twist about an axis extending from the first side frame to the second side frame.

14. The railroad car truck of claim 1 , wherein the transom is configured to enable lateral swing of the first and second side frames together.

15. The railroad car truck of claim 1 , wherein the transom is configured to enable bending along an axis from the first side frame to second side frame.

16. A transom comprising:
a panel assembly;
a first connector assembly connectable to the panel assembly and a first side frame;
a second connector assembly connectable to the panel assembly and the first side frame;
a third connector assembly connectable to the panel assembly and to a second side frame; and
a fourth connector assembly connectable to the panel assembly and to the second side frame,
wherein each connector assembly includes:
a top connection plate,
a spacer connection plate, and
at least one bottom connection plate.

17. The transom of claim 16 , wherein the connection plates of each of the connector assemblies are made from steel.

18. The transom of claim 17 , wherein the connection plates of each of the first and second connector assemblies are weldable to the first side frame and the connection plates of each of the third and fourth connector assemblies are weldable to the second side frame.

19. The transom of claim 16 , wherein each connector assembly includes a first bottom connection plate and a second bottom support plate.

20. The transom of claim 19 , wherein for each connector assembly, the top connection plate, the spacer connection plate, the first bottom connection plate, and the second bottom support plate have decreasing widths along their respective connection edges.

21. The transom of claim 20 , wherein for each connector assembly, the top connection plate, the spacer connection plate, the first bottom connection plate, and the second bottom support plate are vertically aligned.

22. The transom of claim 16 , wherein for each connector assembly, the top connection plate, the spacer connection plate, and the at least one bottom connection plate are positioned to form a space between the top connection plate and the at least one bottom connection plate.

23. The transom of claim 16 , wherein the panel assembly includes a first transom plate, a second transom plate, and a third transom plate.

24. The transom of claim 23 wherein the first transom plate is connected to each of the first, second, third, and fourth connector assemblies by a plurality of fasteners.

25. The transom of claim 23 , wherein the first transom plate defines tapered cutouts extending from opposite ends of the first transom plate.
