Abstract
A disconnect clutch and method of controlling the connection of a parasitic load to an engine disposed on a machine is disclosed. The disconnect clutch may comprise a flywheel assembly, a friction plate and a coupling. The flywheel assembly may include a flywheel having a cavity, a chamber, a piston moveable between a contracted position and an expanded position, a pressure plate, a lever, and a coupling operably connected to the friction plate. The flywheel may include an end plate. The chamber may be defined by the flywheel and the piston. The lever may apply an activation force to the pressure plate when the piston is in the expanded position. The friction plate may be attached to and rotatable with the flywheel assembly when the piston is in the expanded position and generally stationary when the piston is in the contracted position.
