Abstract
The invention is directed to a clutch actuating device for use in a vehicle drivetrain subassembly having a clutch. The clutch actuating device comprises first and second rotating members which are rotatably mounted to a drive member of a vehicle drivetrain subassembly. The first and second rotating members are rotatable relative to the drive member, and are also rotatable relative to each other. First and second clutch loading members are also rotatably mounted to the drive member, and relative to one another, with the first and second clutch loading members engaging one another to cause axial translation relative to one another upon relative rotation therebetween. First and second pilot clutches, including at least one rotatable plate, are coupled to one of the first or second rotating members. The pilot clutches are selectively grounded to cause relative rotation between the first and second rotating members, which in turn causes differential rotation of the clutch loading members. Differential rotation between the clutch loading members causes axial translation of the first clutch loading means relative to the other so as to engage the drivetrain subassembly clutch. Alternatively, the other of the pilot clutches may be activated to cause axial translation in an opposite direction so as to disengage the drivetrain subassembly clutch.
