<P>PROBLEM TO BE SOLVED: To provide a hybrid marine propulsion device which comprises the main engine and a motor, has a compact structure and achieves low fuel consumption by highly efficient drive control. <P>SOLUTION: This marine propulsion device includes: a clutch 7 provided to an input shaft 6 extending from the main engine; a horizontal input/output shaft 8 which is connected to the clutch; a vertical shaft 11 connected to the input/output shaft through an upper bevel gear 9; a horizontal propeller shaft 13 connected to the bottom end of the vertical shaft through a lower bevel gear 12; and a propeller 14 connected to the end of the propeller shaft to which the vertical shaft is not connected. The marine propulsion device turns the propeller around the vertical shaft to set the propulsion direction. A motor-generator 20 is mounted on the top of a base 3, and directly connected to the end of the input/output shaft to which the clutch is not connected. Thus, the marine propulsion device performs a motor propulsion within the low rotating ranges and a hybrid propulsion for assisting the main engine by the motor within the high rotating ranges. <P>COPYRIGHT: (C)2011,JPO&INPIT |
