Abstract
The single-rod shifting device for a motor vehicle manual transmission, in particular for a six-speed transmission, has a central shifting shaft, fork-shaped shifting elements that engage into sliding bushings, and a locking device. The locking device is equipped with a lever ( ) whose rotation point lies on the rotation axis of the axially displaceably mounted central shifting shaft ( ) and which is joined to it via a radial entrainment arrangement. Also provided is a blocking part ( ) that is arranged immovably in the housing in the shifting direction, as well as a coupling drive that converts the rotation of the lever into a linear motion of the blocking elements ( ′ . . . ) on the shifting elements and on the blocking part ( ) ensure that upon superposition of the blocking elements in the shifting direction, a shifting of the shifting elements is prevented.
