Abstract
A transmission having at least one shaft, on which a guide sleeve which has a first external toothing system is arranged fixedly so as to rotate with it and at least one slider sleeve which has an internal toothing system is arranged, it being possible to adjust the slider sleeve between a disengaged position, in which the internal toothing system and a second external toothing system on a clutch element are not operatively connected, and an engaged position, in which the internal toothing system meshes with the second external toothing system. The internal toothing system and/or the first external toothing system are/is configured in such a way that there is merely punctiform contact between them in the engaged position. As a result, in particular, an undesired gear disengagement can be suppressed.

A transmission comprising:
- at least one shaft on which a guide sleeve which has a first external toothing system is arranged fixedly so as to rotate with it and at least one slider sleeve which has an internal toothing system is arranged,
- said slider sleeve being adjustable between a disengaged position, in which the internal toothing system and a second external toothing system on a clutch element are not operatively connected, and an engaged position, in which the internal toothing system meshes with the second external toothing system,
- wherein the internal toothing system and/or the first external toothing system are/is configured in such a way that there is merely punctiform contact between them in the engaged position,
- wherein the first external toothing system of the guide sleeve has a plurality of teeth with, in each case, one thrust flank and one traction flank, at least the thrust flanks having two convex bulges.
