Abstract: A hydraulically-actuated starting clutch adapted for a continuously variable transmission which is located at the output of the transmission to couple the vehicle wheels to the engine upon a signal from the throttle induced system oil pressure. The clutch includes a cover connected to the drive shaft through a hub forming a pressure chamber behind a piston, a Belleville spring acted upon by a pressure disc extending between the spring and the piston and urging a pressure plate against the clutch plate and an end plate secured in the cover, and retractor fingers on said pressure disc engaging said pressure plate. A cooling oil impeller is positioned between the end plate and a clutch plate hub and operatively connected to the end plate, and the clutch plate is operatively connected to a sleeve shaft to drive the differential for the vehicle wheels.

Abstract: A hydraulically actuated starting clutch adapted for a continously variable transmission which is located at the output of the transmission to couple the vehicle wheels to the engine upon a signal from the throttle induced system oil pressure. The clutch includes a cover connected to the drive shaft through a hub forming a pressure chamber behind a piston, a Belleville spring acted upon by the piston and urging a pressure plate against the clutch plate and an end plate secured in the cover. Weights are mounted on the Belleville spring to compensate for the centrifugal effect of the oil in the pressure chamber, and a cooling oil impeller is positioned between the end plate and a clutch plate hub and operatively connected to the end plate. The Belleville spring bears on the hub and cover to retain them in operative driving condition, and the clutch plate is operatively connected to a sleeve shaft to drive the differential for the vehicle wheels.
