Abstract

PURPOSE:To prevent the rattling noise due to torque fluctuation by outputting an oil pressure decreasing signal when an arithmetic result of thrust transmitting rate is 100% upon detection of an on-state of a hydraulic clutch, and outputting an oil pressure increasing signal when the arithmetic result is less than 100%. CONSTITUTION:A thrust transmitting rate computing means 9 computes a thrust transmitting rate according to a rotational speed of an engine 1 detected by a sensor 7 and a rotational speed of a propeller 2 detected by a sensor 8. When an on-state of a hydraulic clutch 3 is detected by a sensor 6, a motor-driven hydraulic control device control means 10 outputs an oil pressure decreasing signal to a motor-driven hydraulic control device 5 if an arithmetic result of the thrust transmitting rate is 100%. On the other hand, if the arithmetic result is less than 100%, the control means 10 outputs an oil pressure increasing signal to the control device 5. Thus, an operating oil pressure of the hydraulic clutch 3 is increased or decreased by a predetermined value, and the above control operation is repeated. Therefore, the operating oil pressure may be always maintained at a minimum value capable of maintaining the thrust transmitting rate of 100%, thereby preventing the generation of a rattling noise. Further, slip of the hydraulic clutch. may be prevented.
