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.

Transmission

A switching mechanism of a multiple change-over gear with an axially displaceable and pivoted gearshift lever shaft having a shift finger formed on the gearshift lever shaft with switching wings which are operatively connected with a synchronization and coupling device for wheels supported on a wheel set shaft of the gearing unit, and with cams formed on the switching wings with which the shift finger can mesh for the execution of a process of gear ratio modification and, over the cams, can axially displace the switching wings.
