  • Patent number: 6827194
    Abstract: An actuation device for a shiftable clutch includes a pressure supply for providing a pressure of a pressure medium for actuating the clutch, and a first and a second workspace independently in communication with the pressure supply for receiving the pressure. A first piston surface is disposed in the first workspace and is operably displaceable in a first direction responsive to the pressure. A second piston surface is disposed in the second workspace and is operably displaceable in a second direction responsive to the pressure. The second direction is oriented opposite to the first direction. One of the first or second piston surfaces is responsive to an application of the pressure in the respective workspace displacing in the respective first or second direction to exert the actuation force.
