Abstract
A clutch assembly configured to selectively engage and disengage a power source and a transmission includes an input member configured for coupling to the power source and an output member configured for coupling to the transmission. A clutch pack is engaged with the input member for co-rotation about an axis. A housing is engaged with the output member and with the clutch pack and is further configured to move in a first direction along the axis and in a second direction opposite to the first direction. The clutch assembly includes a cover and a ring member positioned along the axis from the cover such that the cover and the ring member define a movable chamber therebetween configured to receive a hydraulic fluid. The clutch pack is operable to decouple the input member from the output member in response to a pressure of the hydraulic fluid within the chamber.
