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.
An hydraulic clutch comprising, in combination, an input shaft, a male cone member, interconnector means mounting said male cone member on the input shaft for rotation therewith and for limited axial sliding movement therealong, a female cone member having an open end for receiving the input shaft and male cone member, the female cone member having a conically-shaped, annular wall surrounding the male cone member, and also including a portion shaped to form an output shaft, fluid pressure means including at least one slidable piston for applying sufficient axial pressure to the male cone member to urge the male cone member into engagement with the female cone member, and bearing means for transferring the piston motion to the rotatable male cone member, thereby drivingly coupling the input and output shafts, and means for separating the cone members when the fluid pressure is released.
An hydraulic clutch comprising an input shaft, a first cone member mounted for rotation on said input shaft and for axial sliding motion therealong, an output shaft coaxial with the input shaft and carrying a second cone member adapted for driving engagement with the first cone member, and coupling means for drivingly coupling the cone members, said coupling means including a piston movable in one direction for applying axial force to one cone member, a stop pin mounted for motion with the piston, a stop abutment for limiting the movement of the stop pin and piston, and a return spring for applying force to move the piston toward a clutch-disengaged position.
An hydraulic clutch comprising coaxial first and second shafts, driving and driven clutch cone members respectively coupled to said first and second shafts, fluid power means including a translatably movable piston for urging one cone member into driving engagement with the other cone member, bearing means for transferring piston motion to said one cone member, one of the members being integrally formed with one of the shafts, mechanical means including a resilient element for urging the cone members apart from one another, and a housing forming a chamber containing the cones, the piston, the resilient element and at least part of each of said shafts.
