Abstract

A mobile transport system includes a vehicle frame, first and second pairs of support wheels, first and second drive wheels, and a swing frame pivotable about an swing axis relative to the vehicle frame. The first support wheels are disposed on the vehicle frame, and the second support wheels are disposed on the swing frame. A drive unit including a drive frame is disposed on the swing frame. The first drive wheel is rotatably supported on a first swing arm pivotable about a first swing axis relative to the drive frame, and the second drive wheel is rotatably supported on a second swing arm pivotable about a second swing axis relative to the drive frame. The drive frame is pivotable about a steering axis relative to the swing frame.

First claim

The invention claimed is:

1. A mobile transport system for transporting objects, comprising
a vehicle frame;
a swing frame pivotable about a swing axis relative to the vehicle frame;
a drive unit arranged on the swing frame and including a drive frame, the drive frame being pivotable about a steering axis relative to the swing frame;
a pair of first support wheels arranged on the vehicle frame;
a pair of second support wheels arranged on the swing frame;
a first drive wheel rotatable about a first drive axis extending in a transverse direction and rotatably supported on a first swing arm pivotable about a first swing axis relative to the drive frame; and
a second drive wheel rotatable about a second drive axis extending in the transverse direction and rotatably supported on a second swing arm pivotable about a second swing axis relative to the drive frame;
wherein the steering axis extends in a vertical direction extending perpendicular to the transverse direction.

2. The mobile transport system according to claim 1 , wherein the drive unit includes a swivel attached to the swing frame, the drive frame is pivotable about the steering axis relative to the swivel, and the drive unit includes an actuator motor adapted to drive the drive frame relative to the swivel.

3. The mobile transport system according to claim 1 , wherein the drive unit includes a rotary transmitter adapted to transmit electrical energy and data between the drive frame and the swing frame.

4. The mobile transport system according to claim 1 , wherein a distance between the second support wheels and the swing axis in a base direction is at least approximately equal to a distance between the steering axis and the swing axis in the base direction.

5. The mobile transport system according to claim 1 , wherein the first swing axis extends in the transverse direction, the second swing axis extends in the transverse direction, and/or the first swing axis and the second swing axis are aligned to each other.

6. The mobile transport system according to claim 1 , wherein the drive unit includes a first drive motor arranged on the first swing arm and adapted to drive the first drive wheel and a second drive motor arranged on the second swing arm and adapted to drive the second drive wheel.

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

8. The mobile transport system according to claim 7 , wherein the second support wheels are each supported rotatably relative to the vehicle frame about a second axis of rotation extending in a horizontal direction and are pivotable relative to the vehicle frame about a second pivot axis extending in the vertical direction.

9. The mobile transport system according to claim 1 , wherein the second support wheels are each supported rotatably relative to the vehicle frame about a second axis of rotation extending in a horizontal direction and are pivotable relative to the vehicle frame about a second pivot axis extending in the vertical direction perpendicular to the transverse direction.

10. The mobile transport system according to claim 1 , wherein a braking device is arranged on each of the two support wheels adapted to brake a rotation of the corresponding second support wheel about a second axis of rotation extending in a horizontal direction.

11. The mobile transport system according to claim 1 , wherein the drive wheels are arranged between the first support wheels and the second support wheels in a base direction.

12. The mobile transport system according to claim 1 , wherein at least one inductive sensor adapted to detect a magnetic field of a linear conductor is arranged on the drive frame.

13. A mobile transport system for transporting objects, comprising
a vehicle frame;
a swing frame pivotable about a swing axis relative to the vehicle frame;
a drive unit arranged on the swing frame and including a drive frame, the drive frame being pivotable about a steering axis relative to the swing frame;
a pair of first support wheels arranged on the vehicle frame;
a pair of second support wheels arranged on the swing frame;
a first drive wheel rotatable about a first drive axis extending in a transverse direction and rotatably supported on a first swing arm pivotable about a first swing axis relative to the drive frame; and
a second drive wheel rotatable about a second drive axis extending in the transverse direction and rotatably supported on a second swing arm pivotable about a second swing axis relative to the drive frame;
wherein the first swing arm and the second swing arm are coupled to each other by a coupling unit, such that a pivot motion of the first swing arm about the first swing axis in a first pivot direction causes a pivot motion of the second swing arm about the second swing axis in a second pivot direction arranged opposite the first pivot direction.

14. The mobile transport system according to claim 13 , wherein the coupling unit includes a rocker pivotable about a coupling axis, a first strut connecting the first swing arm to the rocker, and a second strut connecting the second swing arm to the rocker.

15. The mobile transport system according to claim 14 , wherein the coupling axis extends in a longitudinal direction extending perpendicular to the transverse direction.

16. A mobile transport system for transporting objects, comprising
a vehicle frame;
a swing frame pivotable about a swing axis relative to the vehicle frame;
a drive unit arranged on the swing frame and including a drive frame, the drive frame being pivotable about a steering axis relative to the swing frame;
a pair of first support wheels arranged on the vehicle frame;
a pair of second support wheels arranged on the swing frame;
a first drive wheel rotatable about a first drive axis extending in a transverse direction and rotatably supported on a first swing arm pivotable about a first swing axis relative to the drive frame; and
a second drive wheel rotatable about a second drive axis extending in the transverse direction and rotatably supported on a second swing arm pivotable about a second swing axis relative to the drive frame;
wherein the first drive axis and the second drive axis are displaceable relative to each other perpendicular to the transverse direction.

17. A mobile transport system for transporting objects, comprising
a vehicle frame;
a swing frame pivotable about a swing axis relative to the vehicle frame;
