Hydraulic clutch

Patent ·
OSTI ID:6969647
This patent describes a hydraulic clutch comprising: an input member, an output member rotatable coaxially with the input member; friction means provided between the input and output members for selectively engaging and disengaging the members from each other; an annular hydraulic piston slidably mounted on one of the members for selectively actuating the friction means, and having an axially directed back face and an annular coned disc spring interposed between the piston and the friction means, the spring having a radially inner peripheral end, a radially outer peripheral end, and a piston-contacting portion radially intermediate inner and outer peripheral ends. The inner peripheral end is supported on the piston-mounting member at a position apart from the piston, the spring having a cross-sectional shape such that the piston contacting portion is axially closest to the back face of the piston relative to both the inner peripheral end and the outer peripheral end. The piston-contacting portion move gradually radially outwardly with increasing contact pressure by the piston.
