Abstract
The specification discloses a clutch assembly made up of a sleeve and a hub supported on each other for free rotation and being suitable for connecting a drive member to a driven member. The hub and sleeve have friction discs attached to them and the friction discs engage a pressure ring. A supply of oil under pressure is connected to the cavity that receives the clutch plate and when oil is admitted to the friction ring cavity it first fills this cavity then spills over into a cavity containing an actuating piston connected to the pressure ring where the oil forces the actuating piston together with the pressure ring into engagement with the clutch plates thereby forcing them into frictional engagement with each other. A reaction force against the clutch plate is provided by a pressure and adjusting ring from which a reaction force is transmitted to the clutch plate through a Belleville spring. By means of the adjusting ring, the pressure at which the clutch plates will slip can be adjusted.
