Abstract: A shifting device for a drivetrain of a motor vehicle, includes a housing which a first and a second drive shaft are rotatably mounted. The first and second drive shafts are arranged coaxially to one another such that they have a common axis of rotation. The shifting device also includes a shiftable clutch device which is arranged between the first and the second drive shaft. The clutch device has an open shift position in which the first drive shaft is freely rotatable with respect to the second drive shaft, and the clutch device has a closed shift position in which the first drive shaft is connected non-rotatably by the clutch device to the second drive shaft. A control element is displaceable in the direction of the axis of rotation of the drive shafts and, depending on its displacement position, shifts the clutch device to the open or closed shift position.
