Abstract

A shift drum arrangement includes a shift drum with at least one first shift gate and/or a shift drum path for actuating at least one shift element of a transmission, in particular of a motor vehicle. A blocking device has a blocking gate and a blocking pin which engages in the blocking gate. The blocking gate has a labyrinth contour, and therefore the blocking pin strikes against a stop contour in one direction of rotation of the shift drum and blocks the further rotation of the shift drum. The block is released after the shift drum is partially rotated back in the reverse direction of rotation.
