Abstract

The invention relates to a shifting device for the selection of rotationally fixed non-rotational couplings of a plurality of coaxial shafts of a motor-vehicle transmission, comprising a displacement sleeve, which can be axially displaced in relation to a housing and which has internal teeth having two axial toothed sections spaced apart from each other by an axial gap, and which coaxially surrounds a plurality of toothed elements that are arranged axially adjacent to each other and that are each non-rotationally connected to one of the shafts and that each have external teeth corresponding to the internal teeth of the displacement sleeve, wherein the displacement sleeve has a first sleeve part and a second sleeve part that are connected to each other in a manner that is axially fixed and rotationally decoupled, wherein the first sleeve part is a carrier of the first axial toothed section and the second sleeve part is a carrier of the second axial toothed section.
