Chassis for rail vehicle
A chassis for rail vehicles includes at least one support structure, at least one first primary spring and a second primary spring, at least one first drive motor transmission unit connected to the at least one support structure via at least one first suspension element, at least one first wheelset and at least one first clutch connected to the at least one drive motor transmission unit and to the at least first wheelset, wherein the at least first drive motor transmission unit is connected to the at least one support structure via a coupling element that is loadable primarily in the direction of a chassis longitudinal axis so as to create advantageous construction conditions such that an advantageous movability of the support structure and the first wheelset relative to each other is achieved.
1. A chassis for rail vehicles comprising:
at least one support structure;
at least one primary spring and a second primary spring;
at least one first suspension element;
at least one first drive motor transmission unit which is connected to the at least one support structure via the at least one first suspension element;
at least one first wheelset; and
at least one first clutch which is connected to the at least first drive motor transmission unit and to the at least first wheelset;
wherein the at least first drive motor transmission unit is connected to the at least one support structure via a coupling element which is loadable primarily along a longitudinal axis of the chassis such that support and longitudinal force transmission functions are performed independently of one another.
2. The chassis as claimed in claim 1 , wherein a first cross-section surface of the first coupling element is disposed in a vertical longitudinal center plane of the at least one support structure.
3. The chassis as claimed in claim 2 , wherein the first cross-section surface is disposed centrally in the first coupling element.
4. The chassis as claimed in claim 1 , wherein a second cross-section surface of the at least first clutch is disposed in a vertical transverse central plane of the at least first wheelset.
5. The chassis as claimed in claim 2 , wherein a second cross-section surface of the at least first clutch is disposed in a vertical transverse central plane of the at least first wheelset.
6. The chassis as claimed in claim 3 , wherein a second cross-section surface of the at least first clutch is disposed in a vertical transverse central plane of the at least first wheelset.
7. The chassis as claimed in claim 4 , wherein the second cross-section surface is disposed centrally in the at least first clutch.
8. The chassis as claimed in claim 1 , further comprising:
at least one first wheelset actuating device.
9. The chassis as claimed in claim 1 , wherein the first coupling element comprises a spherical bearing.
10. The chassis as claimed in claim 1 , wherein the first coupling element comprises a steering rod.
11. The chassis as claimed in claim 1 , wherein the at least one support structure comprises a chassis frame.
12. The chassis as claimed in claim 1 , wherein the at least first wheelset includes an inner bearing arrangement.
13. The chassis as claimed in claim 1 , wherein the at least first wheelset includes an outer bearing arrangement.
14. The chassis as claimed in claim 1 , further comprising:
a second suspension element disposed between the at least first drive motor transmission unit and the at least one support structure.
