Shifting device for a change-speed gearbox

The invention relates to a switching device for a change-speed gearbox, having at least one sliding sleeve (1) which is placed in a rotationally fixed and axially displaceably on a transmission shaft (3) and to which at least on one side of a respective idler wheel (4) is placed adjacent to the freely rotatable on the transmission shaft (3) is arranged, wherein the at least one sliding sleeve (1) in the direction of a respective idler wheel (4) into a switching position is movable by an actuation of associated actuating means from a neutral position axially and, on reaching the switching position of a coupling of a respective the loose wheel (4) causing the transmission shaft (3), further wherein the associated adjusting means are arranged stationary, and when operated in at least one shift groove (7, 8) engage, which is provided on an outer diameter of the at least one sliding sleeve (1) and one in having axially curved course so that according to the shape of the at least ei NEN shift groove (7; 8) an axial displacement of at least one sliding sleeve (1) be brought about during rotation of the transmission shaft (3).
