Abstract

A carriage body for a railroad vehicle, said carriage body having the following: a base, two lateral walls, each of which is connected to the base, at least two longitudinal supports, each of which lies in the transitional region of the base to the lateral wall on opposing sides of the carriage body and which extend in the longitudinal direction of the carriage body, and a coupling fixing device for fixing a coupling via which the carriage body can be connected to a carriage body of another carriage. The fixing device is arranged below the base, and a lower face of the fixing device is connected directly to the longitudinal supports via a connection.

First claim

The invention claimed is:

1. A carriage body for a railroad vehicle, comprising:
a floor,
two lateral walls, which are each joined to the floor,
at least two longitudinal supports, which are arranged on opposing sides of the carriage body in each transitional region of the floor to the lateral wall and extend in a longitudinal direction of the carriage body,
a coupling fixing device for fixing a coupling via which the carriage body is hooked up to a carriage body of another carriage, wherein the fixing device is arranged beneath the floor, and
wherein a lower face of the coupling fixing device is joined directly to the longitudinal supports via a connection, wherein the connection of the lower face of the coupling fixing device to the longitudinal supports on the opposing sides of the carriage body is continuous such that the lower face of the coupling fixing device and sections of the connection extending from the longitudinal supports to the lower face of the coupling fixing device form a trough-shaped profile in a cross-section running perpendicular to the longitudinal direction of the carriage body, wherein an interior space of the trough lies below the floor of the carriage body, wherein the coupling fixing device is held on the lower face of the floor of the carriage body on a side opposite the side of the carriage body end by at least one plate-shaped element.

2. The carriage body as in claim 1 , wherein the coupling fixing device is a coupling plate and has, on an upper end that is connected to the floor of the carriage body, on a lower end that is joined via the connection to the longitudinal supports, or on the upper end that is connected to the floor of the carriage body and on the lower end that is joined via the connection to the longitudinal supports, a surface that has a receding region arranged between opposing edge regions of the surface such that a hollow space is left in the receding region between the coupling plate and the floor or the connection, and wherein the edge regions are joined to the floor or to the connection to the longitudinal supports via a joint connection that requires a heating of the parts to be joined together.

3. The carriage body as in claim 1 , wherein the coupling fixing device is a coupling plate that has on each lateral end, when viewed in a horizontal cross-sectional area at the lateral ends in proximity to the opposing longitudinal supports of the carriage body, at least one angled region such that when viewed in the horizontal cross-sectional plane, the coupling plate forms a U-shaped profile or, if the lateral ends are angled on both sides, an H-shaped profile, and wherein the coupling plate is joined via the angled region to a force transfer element, via which forces can be transferred between the base of the carriage body and the coupling plate.

4. The carriage body as in claim 1 , wherein the connection is produced by at least one plate-shaped part, wherein opposing outer surfaces of the plate-shaped part extend toward the connection and approximately in the longitudinal direction of the carriage body.

5. The carriage body as in claim 1 , wherein the connection extends over a longitudinal section of the carriage body, in which the connection is joined in two places to the floor of the carriage body via a brace element running from bottom to top to the floor, wherein the two brace elements are spaced apart from one another in a horizontal direction running transversely to the longitudinal direction of the carriage body, and wherein the separation interval defines a space through which the coupling extends from the carriage body end to the coupling fixing device when the coupling is fixed on the coupling fixing device.

6. A railroad vehicle with a carriage body as in claim 1 .

7. The carriage body as in claim 1 , wherein the connection extends in the longitudinal direction of the carriage body over at least a length of the lower face of the coupling fixing device.

8. The carriage body as in claim 1 , wherein the connection is made of at least one plate-shaped part.

9. The carriage body as in claim 8 , wherein the plate-shaped part is an extruded part.

10. The carriage body as in claim 9 , wherein the extrusion direction of the plate-shaped part is aligned with the longitudinal direction of the carriage body.

11. The carriage body as in claim 9 , wherein the plate-shaped part is an extruded aluminum part.

12. The carriage body as in claim 1 , wherein the connection is made of extruded aluminum box profiles.

13. A method for producing a carriage body for a railroad vehicle,
comprising the steps of:
provision of a carriage body floor,
provision of two lateral walls,
arrangement of at least one longitudinal support in the transitional region of the floor to one of the lateral walls, wherein the longitudinal supports extend in a longitudinal direction of the carriage body,
provision of a coupling fixing device for fixing a coupling via which the carriage body can be hooked up to a carriage body of another carriage, wherein the coupling fixing device is arranged beneath the floor, and
joining of each lateral wall to the floor,
wherein a lower face of the coupling fixing device is fixed directly to the longitudinal supports via a connection, and
wherein the connection of the lower face of the coupling fixing device to the longitudinal supports on the opposing sides of the carriage body is configured as a continuous connection such that the lower face of the coupling fixing device and sections of the connection extending from the longitudinal supports to the lower face of the coupling fixing device form a trough-shaped profile in a cross-section running perpendicular to the longitudinal direction of the carriage body, wherein the interior space of the trough lies below the floor of the carriage body, wherein the coupling fixing device is held on the lower face of the floor of the carriage body on a side opposite the side of the carriage body end by at least one plate-shaped element.

14. The method as in claim 13 , wherein provision is made of a coupling plate as a coupling fixing device, wherein the coupling plate is joined on an upper end to the floor of the carriage body and joined on a lower end via a connection to the longitudinal supports, wherein the coupling plate, on the upper end, on the lower end, or the upper end and the lower end, is configured such that the coupling plate has a surface in which a receding region is arranged between opposing edges of the surface such that a hollow space is left in the receding region between the coupling plate and the floor or the connection, and wherein the edge regions are joined to the floor or to the connection by a joint connection that requires a heating of the parts to be joined together.

15. The method as in claim 13 , wherein provision is made of a coupling plate as a coupling fixing device, which has on each lateral end, when viewed in a horizontal cross-sectional area on the ends in proximity to the opposing longitudinal supports of the carriage body, at least one angled region such that, when viewed in the horizontal cross-sectional plane, the coupling plate forms a U-shaped profile or, if the lateral ends are angled on both sides, an H-shaped profile, and wherein the coupling plate is joined via the angled region to a force transfer element, which is joined to the floor of the carriage body such that forces can be transferred by the coupling plate via the force transfer element and by the force transfer element via the coupling plate between the floor of the carriage body and the coupling plate.
