Abstract:
A single-rod shifting device for a six-speed motor vehicle manual transmission comprising a central shifting shaft, having fork-shaped shifting elements in the form of shifting links that engage sliding bushings, and a locking device which, upon shifting of one of the shifting elements out of the neutral position into a shifting position, locks in their neutral positions the shifting elements that are not to be shifted,wherein the locking device has a lever (3,11) whose rotation point lies on the rotation axis of the axially displaceably mounted central shifting shaft (1) and which is joined to it via a radial entrainment arrangement; and has a blocking part (5) that is arranged immovably with respect to the housing in the shifting direction; and has a coupling drive that converts the rotation of the lever (3,11) into a linear motion of the blocking part (5) transversely to the shifting direction of the central shifting shaft (1); and has blocking elements (15, 15â€² . . . ) on the shifting elements (14, 14â€² . . . ) and on the blocking part (5), which are configured in such a way that upon superposition of said blocking elements in the shifting direction, a shifting motion of the shifting elements (14, 14â€² . . . ) is prevented.
