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. Also, a balance cap is operatively connected onto the hub to form a balance chamber in front of the piston to receive oil and compensate for the centrifugal effect of the oil in the pressure chamber behind the piston. |
