Abstract
Official abstract text for this publication.
A car body for a passenger rail vehicle includes a chassis having a front assembly at each vehicle end and a vehicle floor consisting of profiled metal sheet edged in a trapezoidal-like manner within the cross-section, wherein beads of the profiled metal sheet extend in a longitudinal direction of the car body, where the vehicle floor is fixedly connected to each front assembly at transition points to the front assembly via a connecting beam oriented transversely to the longitudinal direction of the car body, where the connecting beam is formed as a profiled metal sheet having a substantially L-shaped cross-section, and where the section of the connecting beam connected to a front assembly is equipped with a trapezoidal-like bead.
First claim
Opening claim text (preview).
The invention claimed is: 1. A car body for a passenger rail vehicle, comprising: a chassis having a front assembly at each respective vehicle end; and a vehicle floor consisting of profiled metal sheet having trapezoidally-shaped beads, when viewed cross-sectionally, the beads of the profiled metal sheet extending in a longitudinal direction of the car body; wherein the vehicle floor is fixedly connected to each front assembly at transition points to said front assembly via a connecting beam oriented transversely to the longitudinal direction of the car body; wherein the connecting beam is formed as a profiled metal sheet having a substantially L-shaped cross-section; and wherein a section of the connecting beam connected to a front assembly includes a trapezoidally-shaped beam having two non-parallel sides connected to a top side. 2. The car body for a passenger rail vehicle according to claim 1 , wherein the connecting beam has cut-outs, through which a section of the vehicle floor extends. 3. The car body for a passenger rail vehicle according to claim 1 , wherein the connecting beam has at least one water outlet borehole. 4. The car body for a passenger rail vehicle according to claim 2 , wherein the connecting beam has at least one water outlet borehole. 5. The car body for a passenger rail vehicle according to claim 1 , wherein the connecting beam is assembled from a number of individual metal sheets welded together. 6. The car body for a passenger rail vehicle according to claim 2 , wherein the connecting beam is assembled from a number of individual metal sheets welded together. 7. The car body for a passenger rail vehicle according to claim 3 , wherein the connecting beam is assembled from a number of individual metal sheets welded together. 8. The car body for a passenger rail vehicle according to claim 1 , wherein the connecting beam is produced in one piece from an individual metal sheet via a deformation method. 9. The car body for a passenger rail vehicle according to claim 2 , wherein the connecting beam is produced in one piece from an individual metal sheet via a deformation method. 10. The car body for a passenger rail vehicle according to claim 3 , wherein the connecting beam is produced in one piece from an individual metal sheet via a deformation method.
