Abstract

A rail vehicle has a bogie, which is covered in such a way that a bogie cavity exists, which is formed in the under floor region of the rail vehicle by a cover assembly and walls adjacent to the bogie. A device for producing pressurized air is connected, with respect to flow, to an air inlet device in the walls of the bogie cavity in such a way that the air can be blown into the bogie cavity.

First claim

The invention claimed is:

1. A rail vehicle, comprising:
a bogie;
a covering arrangement and walls adjacent said bogie in an under floor region of the rail vehicle;
said covering arrangement and said walls together forming a bogie cavity;
an air inlet device formed in said walls of said bogie cavity;
a device for producing pressurized air connected to fluidically communicate with said air inlet device, said device being configured for providing pressurized air with an increased temperature to be blown into said bogie cavity such that added heat is provided for increasing the temperature in said bogie cavity, said device for producing pressurized air controllable such that a pressure produced in said bogie cavity is greater than an exterior ambient pressure outside of said bogie cavity.

2. The rail vehicle according to claim 1 , wherein the rail vehicle has a base plate forming an upper wall of said walls of said bogie cavity and said air inlet device is formed in a portion of the base plate located above said bogie.

3. The rail vehicle according to claim 1 , wherein said walls of said bogie cavity comprise bulkheads disposed forward of said bogie and rearward of said bogie in a longitudinal direction of the rail vehicle, and wherein said air inlet device is provided in at least one of said bulkheads.

4. The rail vehicle according to claim 1 , wherein said air inlet device is configured for blowing the air into said bogie cavity in a planar manner.

5. The rail vehicle according to claim 1 , wherein said air inlet device is configured for blowing the air into said bogie cavity in a punctiform localized manner.

6. The rail vehicle according to claim 1 , wherein said air inlet device is a nozzle that projects into said bogie cavity.

7. The rail vehicle according to claim 1 , wherein said device for producing pressurized air is an exhaust air device of an air-conditioning system of the rail vehicle.

8. The rail vehicle according to claim 1 , wherein said device for producing pressurized air is a transformer cooler of the rail vehicle.

9. The rail vehicle according to claim 1 , wherein said device for producing pressurized air is a power converter cooler of the rail vehicle.

10. The rail vehicle according to claim 1 , wherein the pressurized air is derived from spent air from cooling other components of the rail vehicle and is resistance neutral during further use thereof.
