ABSTRACT:
A clutch actuating device for use in a vehicle drivetrain subassembly having a clutch and a rotatable drive member, comprising a first rotating member which is coupled to the drive member and a second rotating member which is free to rotate relative to the drive member. The first and second rotating members are differentially driven by a gear device and may include first and second ramp surfaces which engage one another so as to permit axial translation of the members relative to one another or alternatively, may comprise threaded screw members which engage one another so as to permit axial translation relative to one another. First and second pilot clutches comprising at least one rotatable plate are provided, with at least one of the pilot clutches being connected to the gear device. Pilot clutch activating devices are provided for selectively activating, and thereby selectively grounding, the first and second pilot clutches, wherein activating one of the first and second pilot clutches causes the second rotating member to translate axially relative to the first rotating member so as to load the drivetrain subassembly clutch, and wherein activating the other of the first and second pilot clutches causes the second rotating member to translate axially relative to the first rotating member so as to unload the drivetrain subassembly clutch.
