Abstract

A thread-reinforced joint device for a coupling device of a vehicle drive, particularly of a low-platform vehicle, includes a plurality of coupling elements, at least one thread packet coupling two adjacent coupling elements so that a force is transmittable, a support device arranged on at least one of the coupling elements for axially guiding the at least one thread packet and at least one elastic body, into which, the at least one thread packet and the coupling elements are at least partially embedded. The coupling elements are designed and/or can be positioned so that the thread-reinforced joint device is adaptable to different mounting interfaces of a respective coupling device.

First claim

What is claimed is:

1. A thread-reinforced joint device for a coupling device of a vehicle drive, comprising:
a plurality of coupling elements configured to allow the thread-reinforced joint device to be adapted to different mounting interfaces of a coupling device;
at least one thread packet configured to couple adjacent ones of the coupling elements for transmission;
a support device arranged on at least one of the adjacent coupling elements and configured to axially guide the at least one thread packet; and
at least one elastic body having at least partially embedded therein the at least one thread packet and the adjacent coupling elements,
wherein in the presence of a plurality of said elastic body and a plurality of said thread packet, each of the elastic bodies has received therein a corresponding one of the thread packets.

2. The thread-reinforced joint device of claim 1 , wherein the elastic bodies are coupled to one another by at least one of the coupling elements.

3. The thread-reinforced joint device of claim 1 , wherein the at least one of the adjacent coupling elements includes a screw thread.

4. The thread-reinforced joint device of claim 1 , wherein at least one of the adjacent coupling elements includes a segment with a predetermined screw head.

5. The thread-reinforced joint device of claim 1 , wherein the at least one of the adjacent coupling elements includes a segment to form a shoulder element.

6. The thread-reinforced joint device of claim 1 , further comprising a bushing configured to receive the at least one of the adjacent coupling elements.

7. A coupling device for a vehicle drive, comprising:
a first flange configured for coupling to a gear unit;
a shaft segment extending through the at least one first flange;
a first thread-reinforced joint device comprising a plurality of coupling elements configured to allow the thread-reinforced joint device to be adapted to different mounting interfaces of a coupling device, at least one thread packet configured to couple adjacent ones of the coupling elements for transmission, a support device arranged on at least one of the adjacent coupling elements and configured to axially guide the at least one thread packet, and at least one elastic body having at least partially embedded therein the at least one thread packet and the adjacent coupling elements, wherein in the presence of a plurality of said elastic body and a plurality of said thread packet, each of the elastic bodies has received therein a corresponding one of the thread packets;
a second flange coupled to the first flange by the first thread-reinforced joint device;
a third flange configured for coupling to a wheel of the vehicle drive, said third flange being coupled to the second flange via the shaft segment; and
a second thread-reinforced joint device arranged on the third flange.

8. The coupling device of claim 7 , wherein the elastic bodies are coupled to one another by at least one of the coupling elements.

9. The coupling device of claim 7 , wherein the at least one of the adjacent coupling elements includes a screw thread.

10. The coupling device of claim 7 , wherein at least one of the adjacent coupling elements includes a segment with a predetermined screw head.

11. The coupling device of claim 7 , wherein the at least one of the adjacent coupling elements includes a segment to form a shoulder element.

12. The coupling device of claim 7 , wherein the first thread-reinforced joint device includes a bushing configured to receive the at least one of the adjacent coupling elements.

13. A drive arrangement for a vehicle, comprising:
a gear unit operably connected to at least one vehicle wheel of the vehicle;
a motor coupled to the gear unit; and
a coupling device arranged between the gear unit and the at least one vehicle wheel, said coupling device including a first flange configured for coupling to the gear unit, a shaft segment extending through the at least one first flange, a first thread-reinforced joint device, a second flange coupled to the first flange by the first thread-reinforced joint device, a third flange configured for coupling to a wheel of the vehicle drive, said third flange being coupled to the second flange via the shaft segment, and a second thread-reinforced joint device arranged on the third flange,
wherein at least one of the first and second thread-reinforced joint devices includes a plurality of coupling elements configured to allow the thread-reinforced joint device to be adapted to different mounting Interfaces of a coupling device, at least one thread packet configured to couple adjacent ones of the coupling elements for transmission, a support device arranged on at least one of the adjacent coupling elements and configured to axially guide the at least one thread packet, and at least one elastic body having at least partially embedded therein the at least one thread packet and the adjacent coupling elements, wherein in the presence of a plurality of said elastic body and a plurality of said thread packet, each of the elastic bodies has received therein a corresponding one of the thread packets.

14. The drive arrangement of claim 13 , wherein the elastic bodies are coupled to one another by at least one of the coupling elements.

15. The drive arrangement of claim 13 , wherein the at least one of the adjacent coupling elements includes a screw thread.

16. The drive arrangement of claim 13 , wherein at least one of the adjacent coupling elements includes a segment with a predetermined screw head.

17. The drive arrangement of claim 13 , wherein the at least one of the adjacent coupling elements includes a segment to form a shoulder element.
