<p>PURPOSE:To reduce an engagement shock of a hydraulic clutch by controlling an oil pressure regulator according to an oil pressure pattern calculated according to a detection signal from sailing condition detecting means at the time of changing-over a forward-backward hydraulic clutch. CONSTITUTION:In a marine speed reducing reversing gear 2 having a forward- backward hydraulic clutch at least, signals from an output shaft rotation sensor 23, an engine rotation sensor 24, forward and backward position sensors 58, 59 and a speed and propulsion direction sensor 65 are input to a control unit 53, and the control unit calculates the optimum oil pressure pattern to a hydraulic clutch according to the sailing condition. When a clutch change-over device 25 is operated, a control signal according to the calculated oil pressure pattern is output to an oil pressure regulator, and engagement and disengagement of a forward and backward clutch is controlled while signals of engagement sensors 60a, 60b are confirmed. Thus, the hydraulic clutch is connected moderately and quickly so as to restrain the occurrence of disadvantages such as an engagement shock of the hydraulic clutch or the like.</p> |
