发明名称 OUTBOARD MOTOR
摘要 A dog clutch selectively meshes with a forward gear and a reverse gear according to an operation of a shift operating member such that connection of the forward gear or the reverse gear to a propeller shaft is changed. A friction clutch transmits the rotation of a drive shaft to the propeller shaft by a first friction surface and a second friction surface contacting together. Before a shifting stage in which the dog clutch meshes with the forward gear or with the reverse gear, a control unit is configured or programmed to control an actuator so as to execute synchronization control by making the first friction surface and the second friction surface of the friction clutch contact one another.

主权项 1. An outboard motor comprising: an engine; a drive shaft extending downward from the engine; a drive gear fixed to the drive shaft; a propeller shaft extending in a direction that intersects the drive shaft; a forward gear meshed with the drive gear; a reverse gear meshed with the drive gear; a shift operating member configured to be operated to change between forward and reverse; a dog clutch disposed on the propeller shaft, the dog clutch being configured to change between connecting the forward gear to the propeller shaft and connecting the reverse gear to the propeller shaft by selectively meshing with the forward gear or the reverse gear according to an operation of the shift operating member; a friction clutch including a first friction surface configured to transmit rotation of the drive shaft, and a second friction surface configured to transmit rotation of the propeller shaft, the friction clutch being configured to transmit rotation of the drive shaft to the propeller shaft by the first friction surface and the second friction surface contacting together; an actuator configured to drive the friction clutch; and a control unit configured or programmed, before a shifting stage in which the dog clutch meshes with the forward gear or with the reverse gear, to execute synchronization control by controlling the actuator to contact the first friction surface and the second friction surface of the friction clutch together.
