Title:
SHIP PROPULSION HYBRID SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/054217
Kind Code:
A1
Abstract:
In this hybrid system (1) for driving a propeller (2), a drive transmission shaft (23) rotates by means of the driving force of one or both of an engine (5) and a motor (6). A marine gear (12) reduces the rotation speed of the drive transmission shaft (23). An engine clutch (41) is disposed in a drive transmission path extending from the engine (5) to the drive transmission shaft (23) and is switched between a connected state and disconnected state. A transmission clutch (42) is disposed in a drive transmission path extending from the drive transmission shaft (23) to the propeller (2) and is switched between a connected state and disconnected state. In an electrical propulsion mode for driving the propeller (2) by means of the motor (6), a control part (14) performs a control that supplies power to the motor (6) to rotate the motor, puts the engine clutch (41) in the disconnected state by cutting off the supply of working oil from a hydraulic pump (45), and thereby puts the transmission clutch (42) in the connected state by supplying working oil from the hydraulic pump (45).
