Document Type and Number:
WIPO Patent Application WO/2022/131247
Kind Code:
A1
Abstract:
In order to provide a vessel propulsion apparatus capable of engaging a clutch even with a difference in rotation between input and output of the clutch to some extent and capable of driving a propeller shaft by either one or both of an engine and an electric motor, clutches (17, 18) are provided between gears (15, 16) meshed with a gear (14) on an engine (2) side and a propeller shaft (11), respectively, and power of the motor (4) is transmitted to the shaft (11) along a path independent of both the clutches (17, 18). The clutches (17, 18) are each configured to: move an engaging element (40) to an engagement position by magnetically attaching, to a rotor (90) through an electromagnet (80), an armature (70) rotationally fixed relative to a cage (50) holding the engaging element (40) between an outward portion (20) on the gear (15, 16) side and an inward portion (30) on the shaft (11) side; and return the armature (70) to a neutral position by a spring (60, 100).
