System and method for pivoting a coupling component

1. A system for pivoting a coupling component for a semi-trailer tractor, comprising:

a rotation device configured to pivot the coupling component between a primary position and a secondary position; and

at least one line configured to be guided via the rotation device into the coupling component;

a pivot arm configured to entrain the at least one line when the coupling component is pivoted between the primary position and the secondary position;

wherein the pivot arm is configured to telescope;

wherein the pivot arm changes a length of the pivot arm when the coupling component is pivoted between the primary position and the secondary position;

wherein the rotation device comprises a disc-shaped turntable rotatable about an axis of rotation; and

wherein an opening for the passage of the at least one line is recessed in the turntable at a distance from the axis of rotation.

2. The system according to claim 1 , wherein the pivot arm has a hollow body area in which the at least one line is at least partially arranged.

3. The system according to claim 2 , wherein the at least one line is configured to be arranged stress-free in the hollow body area in the primary position and the secondary position.

4. The system according to claim 1 , wherein in an assembled state the pivot arm is slidably and/or pivotably mounted on a support element of a vehicle frame in a first area, and pivotably connected to the rotation device in a second area.

5. The system according to claim 4 , further comprising:

a spring element configured to return the pivot arm from the secondary position to the primary position, the spring element being arranged between the first area and the second area.

6. The system according to claim 5 , wherein the spring element is connected with one end to the support element through which the pivot arm is passed.

7. The system according to claim 6 , wherein the spring element comprises a spiral spring which embraces the pivot arm.

8. The system according to claim 7 , wherein the at least one line extends up to the opening on an upper side of the vehicle frame facing away from a roadway and the coupling component is configured to guide the at least one line on the underside of the vehicle frame opposite the upper side below the opening.

9. The system according to claim 7 , wherein the opening in the primary position, viewed in the direction of travel, is arranged behind a pin element for coupling a semi-trailer to a tractor unit.

10. The system according to claim 1 , wherein a ratio of the distance of the opening to the axis of rotation to a radius of the turntable is between 0.25 and 0.78.

11. The system according to claim 10 , wherein the ratio is between 0.3 and 0.65.

12. The system according to claim 11 , wherein the ratio is between 0.35 and 0.45.

13. The system according to claim 10 , wherein a ratio between a radius of the turntable and a length of the pivot arm measured in the longitudinal direction of the pivot arm is between 0.25 and 0.8.

14. The system according to claim 13 , wherein the ratio between the radius of the turntable and the length of the pivot arm is between 0.35 and 0.65.

15. The system according to claim 14 , wherein the ratio between the radius of the turntable and the length of the pivot arm is between 0.45 and 0.55.

16. The system according to claim 1 , wherein the coupling component comprises an outrigger.

17. A method for pivoting a coupling component, comprises:

providing a rotation device configured to pivot the coupling component between a primary position and a secondary position; and

providing at least one line configured to be guided via the rotation device into the coupling component;

wherein a pivot arm for guiding the ate least one line is pivoted between the primary position and the secondary position when the coupling component is pivoted;

wherein the pivot arm is configured to telescope;

wherein the pivot arm changes a length of the pivot arm when the coupling component is pivoted between the primary position and the secondary position;

wherein the rotation device comprises a disc-shaped turntable rotatable about an axis of rotation; and

wherein an opening for the passage of the at least one line is recessed in the turntable at a distance from the axis of rotation.

18. The method of claim 17 , wherein the coupling component comprises an outrigger.
