Abstract
A shifting device for shifting a transmission with a shifting shaft upon which a plurality of shifting forks are located in an axial, slidable manner for carry out desired shifting procedures. The shifting device includes a selection apparatus for choosing the shifting fork to be activated for carrying out the shifting procedure and a blocking mechanism, which prevents movement of each of the non-chosen shifting forks. The blocking mechanism is located on an additional shaft which extends parallel to the shifting shaft and supports elements of the selection apparatus. A first actuator axially displaces the shifting shaft, when carrying out of the shifting procedure, and another actuator causes the additional shaft to rotate for choosing a desired the shifting fork to carry out the shifting procedure and for preventing movement of non-chosen shifting forks.
