Abstract

Transmission element, coupling gear as well as mechanical gear shift for motor vehicle transmission with a transmission element for a mechanical coupling gear with a pipe section shaped outer ring and within the outer ring an axis parallel oriented inner ring a good adjustability to individual requirements is achieved with the possibility to realize force/path characteristics by the fact that between the inner ring and the outer ring several pipe section shaped compression bodies are located.

Claims (24)

1 . A transmission element for a mechanical gear coupling, comprising:

a pipe section shaped outer ring;

a pipe section shaped inner ring within the pipe section shaped outer ring and axial parallel with the pipe section shaped outer ring; and

a plurality of pipe section shaped compression bodies arranged between the pipe section shaped inner ring and the pipe section shaped outer ring.

2 . The transmission element according to claim 1 wherein the pipe section shaped inner ring comprises an annular cross section.

3 . The transmission element according to claim 1 wherein the pipe section shaped outer ring comprises an elliptic cross section.

4 . The transmission element according to claim 1 wherein the plurality of pipe section shaped compression bodies comprise an annular shaped cross section.

5 . The transmission element according to claim 1 wherein the plurality of pipe section shaped compression bodies comprise an elliptic shaped cross section

6 . The transmission element according to claim 1 wherein the plurality of pipe section shaped compression bodies are in a loose arrangement along the pipe section shaped inner ring.

7 . The transmission element according to claim 6 wherein the plurality of pipe section shaped compression bodies are firmly fixed to at least one of the pipe section shaped inner ring and the pipe section shaped outer ring.

8 . The transmission element according to claim 6 wherein the plurality of pipe section shaped compression bodies are incorporated as one piece with at least one of the pipe section shaped inner ring and the pipe section shaped outer ring.

9 . The transmission element according to claim 4 wherein the plurality of pipe section shaped compression bodies are in an axially parallel arrangement to the pipe section shaped inner ring and the pipe section shaped outer ring.

10 . The transmission element according to claim 1 wherein contours of the pipe section shaped inner ring and the pipe section shaped outer ring intersect.

11 . The transmission element according to claim 1 wherein an entire thickness of a wall of at least one of the plurality of pipe section shaped compression bodies where it is in contact with at least one of the pipe section shaped inner ring and the pipe section shaped outer ring is contained within a wall of at least one of the pipe section shaped inner ring and outer ring.

12 . The transmission element according to claim 1 wherein at least one of the pipe section shaped inner ring, the pipe section shaped outer ring, and the plurality of pipe section shaped compression bodies are manufactured from an elastomer.

13 . The transmission element according to claim 1 , wherein the pipe section shaped inner ring, the pipe section shaped outer ring, and the plurality of pipe section shaped compression bodies are manufactured from one piece.

14 . The transmission element according to claim 1 , wherein at least one of the pipe section shaped inner ring and the pipe section shaped outer ring have a plurality of bars running in an axial direction, positioned around the pipe section shaped inner ring in between the plurality of pipe section shaped compression bodies.

15 . The transmission element according to claim 14 , wherein the plurality of bars are formed semi-circular in cross-section.

16 . A mechanical coupling gear; comprising:

a first connector element;

a pipe section shaped outer ring connected with the first connector element;

a pipe section shaped inner ring within the pipe section shaped outer ring and axial parallel with the pipe section shaped outer ring;

a second connector element connected with the pipe section shaped inner ring; and

a plurality of pipe section shaped compression bodies arranged between the pipe section shaped inner ring and the pipe section shaped outer ring.
