Abstract
A positively interlocking shifting device, in particular a claw shifting device for a vehicle transmission. The shifting device comprises at least a first clutch element (1) and a second, axially displaceable clutch element (2). For the interlocking engagement of the corresponding claws (3, 4) of the first and second clutch elements (1, 2), the axially displaceable clutch element (2) can be shifted as soon as a predetermined speed difference, between the two clutch elements (1, 2), is reached. At least one detection device is provided for detecting an offset position between the corresponding claws (3, 4) of the first and the second clutch elements (1, 2), as required for engagement.

A positively interlocking shifting device for a vehicle transmission, the positively interlocking shifting device comprising:
- at least a first rotating clutch element (1) and a second, rotating and axially displaceable clutch element (2), for the interlocking engagement of corresponding claws (3, 4) of the first and the second clutch elements (1, 2);
- the axially displaceable clutch element (2) being shifted as soon as a predetermined speed difference, between the first and the second clutch elements (1, 2) is reached;
- at least one detection device being provided for detecting a position offset between the corresponding claws (3, 4) of the first and the second clutch elements (1, 2), as required for engagement.
A positively interlocking shifting device for a vehicle transmission, the shifting device comprising:
- first and second clutch elements being engageable with one another, and each of the first and the second clutch elements comprising a plurality of claws and being rotatable;
- the second clutch element being axially displaceable when a difference in a rotational speed of the first clutch element and a rotational speed of the second clutch element is equal to a predetermined rotational speed difference;
- and
- a detection device for detecting a positional offset between the claws of the first clutch element and the claws of the second clutch element, and the positional offset being required for engagement of the claws of the first and the second clutch elements.
