Title: Hydraulically actuated starting clutch assembly
Inventor: MCCOLL JOHN W
IPC: F16D25/0635
Filed: 1985-12-05
Granted: 1991-07-30
Abstract: 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.
