Abstract

A rail vehicle includes a bogie, a bogie cavity in which the bogie is embedded, and a bogie cladding via which the bogie is at least partially clad, where the bogie cladding includes an opening, and where the bogie includes a flow-inhibitor arranged at the opening to reduce the inflow of air through the opening into the bogie cavity in order to reduce the inflow of air through the opening into the bogie cavity in an economical manner.

First claim

The invention claimed is:

1. A rail vehicle, comprising:
a bogie;
a bogie cavity into which the bogie is embedded; and
a bogie cladding via which the bogie is at least partially clad, the bogie cladding including an opening;
wherein the bogie cladding includes a planar flow inhibitor arranged at the opening and extends across a width of the rail vehicle and is oriented along a longitudinal direction of the bogie cladding or surrounds a wheelset bearing protruding from the opening in the circumferential direction thereof to reduce an inflow of air through the opening into the bogie cavity.

2. The rail vehicle as claimed in claim 1 , wherein the flow-inhibitor is elastically deformable.

3. The rail vehicle as claimed in claim 2 , wherein the flow-inhibitor is formed as a brush.

4. The rail vehicle as claimed in claim 2 , wherein the opening is an opening of a cladding element of the bogie cladding through which an element of the bogie is guided.

5. The rail vehicle as claimed in claim 1 , wherein the flow-inhibitor is formed as a brush.

6. The rail vehicle as claimed in claim 5 , wherein the opening is an opening of a cladding element of the bogie cladding through which an element of the bogie is guided.

7. The rail vehicle as claimed in claim 1 , wherein the flow-inhibitor is formed as a sealing lip.

8. The rail vehicle as claimed in claim 7 , wherein the opening is an opening of a cladding element of the bogie cladding through which an element of the bogie is guided.

9. The rail vehicle as claimed in claim 1 , wherein the bogie cladding includes a first cladding element and a second cladding element arranged adjacent to the first cladding element; and wherein said opening is a gap between the first and the second cladding element.

10. The rail vehicle as claimed in claim 9 , wherein the first and the second cladding elements are attached to the bogie.

11. The rail vehicle as claimed in claim 10 , further comprising:
a further flow-inhibitor arranged at the opening to reduce an inflow of air through the opening into the bogie cavity;
wherein the flow-inhibitor is attached to the first cladding element and the further flow-inhibitor is attached to the second cladding element.

12. The rail vehicle as claimed in claim 11 , wherein at least one of (i) the flow-inhibitor is in contact with the second cladding element and (ii) the further flow-inhibitor is in contact with the first cladding element.

13. The rail vehicle as claimed in claim 9 , further comprising:
a body;
wherein the first and the second cladding element are attached to the body.

14. The rail vehicle as claimed in claim 13 , further comprising:
a further flow-inhibitor arranged at the opening to reduce an inflow of air through the opening into the bogie cavity;
wherein the flow-inhibitor is attached to the first cladding element and the further flow-inhibitor is attached to the second cladding element.

15. The rail vehicle as claimed in claim 14 , wherein at least one of (i) the flow-inhibitor is in contact with the second cladding element and (ii) the further flow-inhibitor is in contact with the first cladding element.

16. The rail vehicle as claimed in claim 9 , further comprising:
a further flow-inhibitor arranged at the opening to reduce an inflow of air through the opening into the bogie cavity;
wherein the flow-inhibitor is attached to the first cladding element and the further flow-inhibitor is attached to the second cladding element.

17. The rail vehicle as claimed in claim 16 , wherein the flow-inhibitor are spaced apart from one another.

18. The rail vehicle as claimed in claim 16 , wherein the flow-inhibitor are at least one of (i) in contact with one another and (ii) engage in one another.

19. The rail vehicle as claimed in claim 16 , wherein at least one of (i) the flow-inhibitor is in contact with the second cladding element and (ii) the further flow-inhibitor is in contact with the first cladding element.

20. The rail vehicle as claimed in claim 1 , wherein the opening is an opening of a cladding element of the bogie cladding through which an element of the bogie is guided.

21. The rail vehicle as claimed in claim 9 , further comprising:
a body;
wherein one of:
(i) the first cladding element is attached to the bogie and the second cladding element is attached to the body and
(ii) the first cladding element is attached to the body and the second cladding element is attached to the bogie.

22. The rail vehicle as claimed in claim 21 , further comprising:
a further flow-inhibitor arranged at the opening to reduce an inflow of air through the opening into the bogie cavity;
wherein the flow-inhibitor is attached to the first cladding element and the further flow-inhibitor is attached to the second cladding element.
