In a clutch toothing of a shift clutch, mutually confronting tooth ends of the clutch teeth of two clutch rings are equipped, for the axial insertion of the clutch teeth, with two angled unequal length sloping faces, which sloping faces have an equal length along the direction of the clutch axis and a common vertex. One clutch ring and a synchronizing ring mounted on the clutch rings so as to be rotatably and axially movable to a limited extent are equipped with matching blocking faces. The blocking faces of the respective rings likewise have the same axial extent along the axial direction of the clutch axis. To prevent renewed relative rotations after completed synchronism as a result of external forces on a synchronously unstable clutch ring, the vertex on the one clutch ring is offset in the direction of the relative rotation cancelling the synchronism and the vertex on the other clutch ring is offset in the opposite direction in relation to the tooth mid-plate, containing the clutch axis, of the respective clutch tooth. |
