Abstract

A shifting device for a motor vehicle transmission includes several transmission shafts which each are rotatable about a transmission axis, a synchronizer ring which is firmly connected with a transmission shaft, a first disk carrier, a plurality of first disks which are non-rotatably and axially shiftably connected with the first disk carrier, a second disk carrier which is axially shiftable relative to the first disk carrier and in circumferential direction can be coupled with the synchronizer ring both frictionally and positively, a plurality of second disks which are non-rotatably and axially shiftably connected with the second disk carrier and form a multidisk clutch with the first disks, and an actuating body for axially pressurizing the second disk carrier, wherein the actuating body and the second disk carrier are rotatable relative to each other in circumferential direction and substantially are firmly connected with each other in axial direction.
