ABSTRACT:
A multi-plate friction torque transmitting device has a plurality of friction plates which are controlled between engaged and disengaged conditions by a fluid-operated piston. The piston is comprised of an apply piston portion and a take-up piston portion. The take-up piston portion responds rapidly when pressurized to remove the disengaged clearance between the friction plates and initiates the engagement condition. The apply piston is operable to provide the high forces necessary for a complete engagement. These high forces are transmitted through a fluid medium disposed between the apply piston and the take-up piston. A centrifugal mechanism is operable on the take-up piston to counteract the centrifugal forces applied thereto during the disengaged condition.
