Abstract
A clutch assembly includes a clutch pack, and a rotating control piston selectably engageable with the clutch pack via movement of the clutch piston along an axis of rotation of the control piston. The clutch piston includes a piston member engageable with the clutch pack, a cover plate installed into the piston member to define an enclosed volume, and an axially fixed chamber divider positioned in the enclosed volume to divide the enclosed volume into a control pressure chamber and a pressure balancing chamber. Both the control pressure chamber and the pressure balancing chamber are filled with hydraulic fluid, and the control piston is moved between a disengaged position and an engaged position via modulation of hydraulic pressure in the control pressure chamber.
