Carrying structure of a rail vehicle

1. A carrying structure of a rail vehicle, comprising:

at least one coupling element arranged below a carriage body such that the carriage body is supported by the at least one coupling element;

at least one of a positive connection and a non-positive connection connecting the at least one coupling element to the carrying structure;

wherein at least a part of the carrying structure disposed below or above at least one of the positive connection and the non-positive connection or at least one surface upwardly delimiting the coupling element is configured as a supporting element.

2. The carrying structure as claimed in claim 1 , wherein the at least one coupling element has a longitudinal axis, and wherein the supporting element is arranged coaxially with respect to the longitudinal axis of the at least one coupling element.

3. The carrying structure as claimed in claim 2 , wherein the part of the carrying structure disposed below at least one of the positive connection and the non-positive connection , which is formed as a supporting element, is formed as a thread of a bore hole in the carrying structure.

4. The carrying structure as claimed in claim 2 , wherein that the part of the carrying structure disposed below at least one of the positive connection and the non-positive connection, which is formed as the supporting element, is a balcony-shaped mold of the carrying structure.

5. The carrying structure as claimed in claim 2 , wherein the part of the carrying structure disposed below at least one of the positive connection and the non-positive connection, which is formed as the supporting element, is a delimitation of a blind hole in the carrying structure.

6. The carrying structure as claimed in claim 1 , wherein that the part of the carrying structure disposed below at least one of the positive connection and the non-positive connection, which is formed as the supporting element, is a balcony-shaped mold of the carrying structure.

7. The carrying structure as claimed in claim 1 , wherein the part of the carrying structure disposed below at least one of the positive connection and the non-positive connection, which is formed as the supporting element, is a delimitation of a blind hole in the carrying structure.

8. The carrying structure as claimed in claim 1 , wherein the part of the carrying structure disposed below at least one of the positive connection and the non-positive connection, which is formed as a supporting element, is formed as a thread of a bore hole in the carrying structure.

9. The carrying structure as claimed in claim 1 , wherein a lifting apparatus is supportable or supported on the supporting element.

10. The carrying structure as claimed in claim 9 , wherein the lifting apparatus comprises one of (i) a hydraulic drive unit for power generation, (ii) a mechanical drive unit for power generation, (iii) an electrical drive unit for power generation and (iv) a pneumatic drive unit for power generation for power generation.

11. The carrying structure as claimed in claim 10 , wherein the mechanical drive unit is a spindle.

12. The carrying structure as claimed in claim 10 , wherein the hydraulic drive unit is a piston of a hydraulic cylinder.

13. The carrying structure as claimed in claim 9 , wherein the lifting apparatus is arrangeable or arranged in one of (i) the blind hole or in the bore hole in the carrying structure, (ii) between the coupling element and the carriage body, (iii) within the coupling element and (iv) in a lower region of the carriage body.

14. The carrying structure as claimed in claim 1 , wherein the coupling element is a secondary spring of the rail vehicle.

15. The carrying structure as claimed in claim 14 , wherein the secondary spring is formed as one of (i) a hydraulic spring, (ii) a helical spring and (iii) a pneumatic spring.
