A device for connecting two free ends of a rubber band track to one another or for connecting the ends of several band segments to one another. The device has two or more tubes and a pin rubber-mounted in the respective tube. The tubes are in each case inserted into the one end and into the other en
A device for connecting two free ends of a rubber band track to one another or for connecting the ends of several band segments to one another. The device has two or more tubes and a pin rubber-mounted in the respective tube. The tubes are in each case inserted into the one end and into the other end of the rubber band track or of the band segments, and at least one connector, by way of which the pins are coupled together in a rotationally fixed manner. The rotational rigidity of the pins in relation to their respective tube, brought about by the rubber mounting, is adjusted in dependence on the flexural strength of the rubber band track or of the band segments in the region of the ends.

1. A device for connecting first and second free ends of a rubber link track to one another or for connecting first and second free ends of first and second band segments, respectively, of a rubber band track to one another, the device comprising: at least two tubes each having a pin mounted therein
1. A device for connecting first and second free ends of a rubber link track to one another or for connecting first and second free ends of first and second band segments, respectively, of a rubber band track to one another, the device comprising: at least two tubes each having a pin mounted therein with a rubber mounting, wherein one of said tubes is to be inserted into the first end of the rubber band track or of a band segment and another one of said tubes is to be inserted into the second end of the rubber band track or of a band segment; andat least one connector configured to couple said pins together in a rotationally fixed manner;wherein a rotational rigidity of said pins relative to a respectively associated said tube, brought about by the rubber mounting, is adjusted via a thickness of the rubber mounting between said pins and an inside surface of said tube or via a force to be applied when pressing said pins into the respective said tube and a compression of the rubber mounting in connection with the pressing-in process. 2. The device according to claim 1, wherein a value of the rotational rigidity of said pins in relation to the respective said tube, at least in an application-specific pivoting angle region of the ends of the rubber band track or of the ends of the band segments in relation to each other, does not exceed a value of a flexural strength of the rubber band track or of the band segments in the region of the ends. 3. The device according to claim 2, wherein the value of the rotational rigidity of said pins is less than the flexural strength of the rubber band track or of the band segments in the region of the ends at least by a factor of between 1.5 and 4 times. 4. The device according to claim 2, wherein the value of the rotational rigidity of said pins in relation to the flexural strength of the rubber band track or of the band segments is negligibly small in a region of the ends. 5. The device according to claim 2, wherein the application-specific pivoting angle region of the ends of the rubber band track or of the band segments in relation to each other is between 0 and 30 degrees. 6. The device according to claim 2, wherein the application-specific pivoting angle region of the ends of the rubber band track or of the band segments in relation to each other is between 0 and 60 degrees. 7. The device according to claim 2, wherein the application-specific pivoting angle region of the ends of the rubber band track or of the band segments in relation to each other is between 0 and 80 degrees. 8. The device according to claim 1, wherein the rotational rigidity of the pins in relation to their respective tube, brought about by the rubber mounting, is adjusted in dependence on the weight of the vehicle on which the rubber band track is to be fitted. 9. The device as claimed in claim 8, wherein the rotational rigidity of said pins, brought about by the rubber mounting, when the pins are rotated by 15 degrees in relation to the respective said tube has a value of: approximately 5 Nm at a vehicle weight of 4000 kg;approximately 7 Nm at a vehicle weight of 8000 kg;approximately 12 Nm at a vehicle weight of 12000 kg;approximately 18 Nm at a vehicle weight of 15000 kg;approximately 23 Nm at a vehicle weight of 18000 kg; andapproximately 25 Nm at a vehicle weight of 20000 kg. 10. The device according to claim 8, wherein the rotational rigidity of said pins in relation to the respective said tube, brought about by the rubber mounting, is adjusted via a tensile stress of the rubber compound, and the tensile stress is greater with a greater vehicle weight. 11. The device according to claim 10, wherein the tensile stress300 to DIN 53504 of the rubber compound at vehicle weights of between 4000 kg and 20000 kg is approximately between 3.8 MPa and 12.4 MPa. 12. The device according to claim 1, wherein the thickness of the rubber mounting is provided by an approximately constant ratio between a diameter of said pin and the inside diameter of the tube, the diameter of said pin being all the bigger, the greater the vehicle weight. 13. The device according to claim 1, wherein the pressing-in force applied and the compression of the rubber mounting connected thereto is all the greater, the greater the vehicle weight. 14. The device as claimed in claim 13, wherein a value of the pressing-in force at a vehicle weight in a range between 4000 kg and 20000 kg lies between approximately 35 kN and approximately 80 kN. 15. A rubber track, comprising: first and second ends, and a singe connector device according to claim 1 connecting said first and second ends to form a closed track;a tube having a pin rubber-mounted therein being inserted in each of said first and second ends;said pins being coupled to one another in a rotationally fixed manner by way of at least one connector; andwherein a rotational rigidity of said pins in relation to the respective said tube, brought about by a rubber mounting, is adjusted in dependence on a flexural strength of the rubber track in a region of said ends. 16. The rubber band track, comprising: a plurality of band segments with ends connected to each other by one or more connector devices according to claim 1 to form a closed track;wherein in each case a tube having a pin which is rubber-mounted in said tube is inserted in each of the ends of the band segments;wherein said pins of two said band segments are connected to each other in a rotationally fixed manner by way of at least one connector; andwherein the rotational rigidity of the pins in relation to a respective said tube, brought about by the rubber mounting, is adjusted in dependence on a flexural strength of the band segments in the region of the ends. 17. The rubber band track according to claim 16, wherein said band segments each have a base body made of rubber, and said base body has tensile-resisting inserts vulcanized into the rubber and configured to wrap around said tubes that are transversely inserted in said base body.
