HYDRAULICALLY ACTUATED STARTING CLUTCH ASSEMBLY ABSTRACT: A hydraulically actuated starting clutch (10) 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 (52) connected to the drive shaft (11) through a hub (33) forming a pressure chamber (44) behind a piston (45), a Belleville spring (81) acted upon by the piston (45) and urging a pressure plate (62) against the clutch plate (65) and an end plate secured in the cover. Weights (85) are mounted on the Belle- ville spring (81) to compensate for the centrifugal effect of the oil in the pressure chamber, and a cooling oil impeller (75) is positioned between the end plate (56) and a clutch plate hub (67) and operatively connec- ted 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. Also, the hydraulic pressure acting on the secondary pulley of the continuously variable transmission to change its effective diameter simulta- neusly acts on the piston actuating the clutch.
