  • Patent number: 9016453
    Abstract: A connecting device (1) for the rotationally fixed connection of first and second shafts (2, 3) that can rotate relative to one another. The connecting device (1) comprises an axially movable connecting element (5) designed such that, in a first axial position (A), the connecting element (5) forms an interlock between the first and second shafts (2, 3) and, in a second axial position (B), the connecting element (5) releases the interlock. The connecting device (1) also comprises an actuating system (6, 8, 9, 10, 11) for moving the connecting element between the first and second axial positions (A, B) and a stop (16) which limits the axial movement of the connecting element (5) in the first or second axial position (A, B). An impact damper (17) is provided for the stop (16) in order to reduce annoying noise when the connecting element (5) strikes against the stop (16).
