Abstract

A mobile transport system for transporting objects in a technical system, includes a vehicle frame, a first wheel pair, a second wheel pair, and a third wheel pair, each having two wheels rotatable relative to the vehicle frame, and a swing frame pivotable about a swing axis extending in a transverse direction relative to the vehicle frame. The first wheels of the first wheel pair are attached to the vehicle frame, and the second wheels of the second wheel pair are attached to the swing frame. The third wheels of the third wheel pair are attached to a tilt frame pivotable relative to the swing frame about a tilt axis extending approximately in the longitudinal direction.

First claim

The invention claimed is:

1. A mobile transport system for transporting objects in a technical system, comprising:
a vehicle frame;
a swing frame pivotable about a swing axis extending in a transverse direction relative to the vehicle frame;
a tilt frame pivotable relative to the swing frame about a tilt axis extending approximately in a longitudinal direction;
a first wheel pair including two first wheels rotatable relative to the vehicle frame and attached to the vehicle frame;
a second wheel pair including two second wheels rotatable relative to the vehicle frame and attached to the swing frame; and
a third wheel pair including two third wheels rotatable relative to the frame and attached to the tilt frame;
wherein a braking device is arranged on each of the third wheels and is adapted to brake a rotation of the third wheel about an axis of rotation extending in a horizontal direction.

2. The mobile transport system according to claim 1 , wherein the first wheels and/or the third wheels are arranged as support wheels, are pivotable relative to the vehicle frame about a pivot axis extending a vertical direction, and are supported rotatably relative to the vehicle frame about an axis of rotation extending in a horizontal direction.

3. The mobile transport system according to claim 1 , wherein the first wheels are arranged as support wheels, are pivotable relative to the vehicle frame about a pivot axis extending a vertical direction, and are supported rotatably relative to the vehicle frame about an axis of rotation extending in a horizontal direction.

4. The mobile transport system according to claim 1 , wherein the third wheels are arranged as support wheels, are pivotable relative to the vehicle frame about a pivot axis extending a vertical direction, and are supported rotatably relative to the vehicle frame about an axis of rotation extending in a horizontal direction.

5. The mobile transport system according to claim 1 , wherein the first wheels and the third wheels are arranged as support wheels, are pivotable relative to the vehicle frame about a pivot axis extending a vertical direction, and are supported rotatably relative to the vehicle frame about an axis of rotation extending in a horizontal direction.

6. The mobile transport system according to claim 1 , wherein the second wheels are arranged as drive wheels, are rotatably supported relative to the swing frame about a drive axis extending in the transverse direction, and are adapted to be driven by a drive unit.

7. The mobile transport system according to claim 1 , wherein the first wheels, the second wheels, and/or the third wheels are arranged offset to each other in the transverse direction.

8. The mobile transport system according to claim 1 , wherein the first wheels are arranged offset to each other in the transverse direction, the second wheels are arranged offset to each other in the transverse direction, and/or the third wheels are arranged offset to each other in the transverse direction.

9. The mobile transport system according to claim 1 , wherein a distance between the second wheels from each other in the transverse direction is greater than a distance of the first wheels from each other in the transverse direction, and/or a distance of the second wheels from each other in the transverse direction is greater than a distance of the third wheels from each other in the transverse direction.

10. The mobile transport system according to claim 1 , wherein a distance between the second wheels from each other in the transverse direction is greater than a distance of the first wheels from each other in the transverse direction.

11. The mobile transport system according to claim 1 , wherein a distance of the second wheels from each other in the transverse direction is greater than a distance of the third wheels from each other in the transverse direction.

12. The mobile transport system according to claim 1 , wherein a distance between the second wheels from each other in the transverse direction is greater than a distance of the first wheels from each other in the transverse direction, and a distance of the second wheels from each other in the transverse direction is greater than a distance of the third wheels from each other in the transverse direction.

13. The mobile transport system according to claim 1 , the second wheels are arranged between the first wheels and the third wheels in the longitudinal direction.

14. The mobile transport system according to claim 1 , wherein a distance from the second wheels to the swing axis in the longitudinal direction is at least approximately equal to a distance from the third wheels to the swing axis in the longitudinal direction.

15. The mobile transport system according to claim 1 , wherein a distance from the second wheels to the swing axis in the longitudinal direction is equal to a distance from the third wheels to the swing axis in the longitudinal direction.

16. The mobile transport system according to claim 1 , further comprising a receiving unit arranged on the swing frame and adapted to receive energy transferred inductively from a charging unit.

17. The mobile transport system according to claim 1 , further comprising at least one inductive sensor arranged on the swing frame and adapted to detect a magnetic field.

18. The mobile transport system according to claim 1 , further comprising an angle sensor adapted to detect a pivot angle of the swing frame relative to the vehicle frame about the swing axis.

19. The mobile transport system according to claim 1 , further comprising an angle sensor adapted to detect a pivot angle of the tilt frame relative to the swing frame about the tilt axis.

20. The mobile transport system according to claim 1 , further comprising a first angle sensor adapted to detect a pivot angle of the swing frame relative to the vehicle frame about the swing axis and a second angle sensor adapted to detect a pivot angle of the tilt frame relative to the swing frame about the tilt axis.

21. A mobile transport system for transporting objects in a technical system, comprising:
a vehicle frame;
a swing frame pivotable about a swing axis extending in a transverse direction relative to the vehicle frame;
