Abstract
An hydraulic clutch is provided, which is positively engaged by hydraulic means, and is disengaged by mechanical means. The clutch includes a male cone member carried for rotation on an input shaft, and for limited axial sliding movement therealong. Interconnection between the male cone member and the input shaft is provided by a series of elongated pins carried in recesses formed in the male cone member and in the input shaft. A female cone member, formed integrally with an output shaft, receives the male cone member for driving engagement. When engagement is desired, a fluid pressure piston and thrust plate urge the male cone member axially along the input shaft into driving engagement with the female cone member. A stop pin carried by the thrust plate engages an abutment for limiting the axial motion of the hydraulic piston and male cone member. When disengagement is desired, fluid pressure is released, and a resilient mechanical device such as a set of springs urges the male cone member out of engagement with the female cone member. A second mechanical device such as an additional set of springs returns the thrust plate and piston to their deactivated positions.
