<p><P>PROBLEM TO BE SOLVED: To provide a wet clutch brake control device preventing shock on operating a clutch brake without requiring complicated and large hydraulic control circuit and skill of press operation. <P>SOLUTION: The hydraulic control device of the wet clutch brake 10 for selectively operating either a clutch mechanism 15 or a brake mechanism 20 by a clutch cylinder 25 provided between a flywheel W and a crankshaft A to which a rotation power is supplied from an external driving source is provided with a hydraulic cylinder 30 for supplying hydraulic oil to the clutch cylinder 25, a screw/nut mechanism 33 for moving a piston 32 of the hydraulic cylinder 30 forward and backward and a servo motor 38 for rotation control of the screw/nut mechanism 33. As its component only includes the hydraulic cylinder 30 driven by the servo motor 38 basically, a complicated and large hydraulic circuit is not required. The hydraulic control device controls only a rotation quantity of the servo motor 38, skill is not required for the press operation. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
