Abstract

A connecting member for connecting two longitudinal members of a bogie frame of a rail vehicle includes at least one fastening point for receiving add-on components, at least a first member element with a first member portion and a second member element with a second member portion, wherein the first and second member elements are connected to one another in a force-fitting manner by at least two connecting devices such that the member portions overlap one another at least in certain portions in order to damp vibrations that occur and to thus prevent oscillation of the system.

First claim

The invention claimed is:

1. A connecting member for connecting two longitudinal members of a bogie frame of a rail vehicle, said connecting member comprising:
at least one fastening point for receiving add-on components; at least a first member element with a first member portion and a second member element with a second member portion; and
at least one fastening element is provided for connecting the connecting member to a respective longitudinal member of the bogie frame;
wherein the first and second member elements are connected to one another in a force-fitting manner by at least two connecting means such that the first and second member portions overlap one another at least in certain portions; and
wherein the at least one fastening element includes a contact portion which is arranged between the two fastening portions of the member elements and is connected to the first and second member elements via the connecting means.

2. The connecting member as claimed in claim 1 , wherein the first member element and the second member element are formed as a strip in a region of the first and second member portions.

3. The connecting member as claimed in claim 1 , wherein the first member element and the second member element have an open profile in cross-section.

4. The connecting member as claimed in claim 3 , wherein the open profile is an L profile.

5. The connecting member as claimed in claim 3 , wherein the open profile is a U profile.

6. The connecting member as claimed in claim 2 , wherein the first member element and the second member element have an open profile in cross-section.

7. The connecting member as claimed in claim 1 , wherein the first and second member elements have a plurality of openings in the overlapping first and second member portions.

8. The connecting member as claimed in claim 1 , wherein the first and second member elements have two fastening portions overlapping in each case; and wherein the at least two connecting means are arranged in the fastening portions.

9. The connecting member as claimed in claim 8 , wherein the two fastening portions are arranged at ends of the first and second member portions, said ends facing in a direction of the two longitudinal members in a mounted state.

10. The connecting member as claimed in claim 1 , wherein at least one the fastening elements formed as a mounting bracket.

11. The connecting member as claimed in claim 10 , wherein the at least one fastening element is formed in an L-shape.

12. The connecting member as claimed in claim 10 , wherein the at least one fastening element includes at least one elastomer element via which the at least one fastening element is connectable to the respective longitudinal member.

13. The connecting member as claimed in claim 1 , wherein the at least one fastening element is formed in an L-shape.

14. The connecting member as claimed in claim 1 , wherein the at least one fastening element includes at least one elastomer element via which the at least one fastening element is connectable to the respective longitudinal member.

15. The connecting member as claimed in claim 1 , wherein the first member element includes at least one receiving portion which protrudes at an angle from the first member portion; and wherein at least one fastening point is arranged on the at least one receiving portion.

16. The connecting member as claimed in claim 1 , wherein the at least one receiving portion protrudes at a right angle from the first member portion.

17. The connecting member as claimed in claim 1 , wherein the second member element includes at least one further receiving portion which protrudes at an angle from the second member portion; and wherein at least one fastening point is arranged on the at least one further receiving portion.

18. The connecting member as claimed in claim 1 , wherein the at least one further receiving portion protrudes at a right angle from the second member portion.

19. The connecting member as claimed in claim 1 , wherein the first and second member portions form between 70% and 90% of a length of the first and second member elements.

20. The connecting member as claimed in claim 1 , wherein the first and second member portions form between 80% and 90% of the length of the first and second member elements.

21. The connecting member as claimed in claim 1 , wherein the first and second the member elements are implemented as sheet metal bent parts are implemented as sheet metal bent parts.

22. The connecting member as claimed in claim 1 , wherein the first and second the member elements and the at least one fastening element are implemented as sheet metal bent parts.

23. The connecting member as claimed in claim 21 , wherein the sheet metal bent parts are fabricated from stainless steel.

24. A bogie frame of a rail vehicle having two longitudinal members and at least one connecting member connecting the two longitudinal members as claimed in claim 1 .

25. The bogie frame as claimed in claim 24 , wherein the connecting member includes a right angle with the two longitudinal members.

26. The bogie frame as claimed in claim 25 , wherein a cross-section of the first member element is open in a longitudinal direction of the bogie frame and a cross-section of the second member element is open in a direction counter to the longitudinal direction of the bogie frame.

27. The bogie frame as claimed in claim 24 , wherein a cross-section of the first member element is open in a longitudinal direction of the bogie frame and a cross-section of the second member element is open in a direction counter to the longitudinal direction of the bogie frame.

28. The bogie frame as claimed in claim 24 , wherein a length of the first and second member elements amounts to between 80% and 120% of the clear width between the two longitudinal members.

29. The bogie frame as claimed in claim 24 , wherein the length of the first and second member elements amounts to between 90% and 110% of the clear width between the two longitudinal members.

30. The bogie frame as claimed in claim 24 , wherein the connecting member is connected to the two longitudinal members via the fastening elements.

31. The bogie frame as claimed in claim 24 , wherein the fastening elements include a projecting portion which extends in a direction of respective longitudinal members.

32. The bogie frame as claimed in claim 24 , wherein the connecting member is arranged behind a wheel axle of the rail vehicle when viewed from a transom member of the bogie frame.
