POWER STEERING SYSTEM OF OUTBOARD MOTOR

摘要

A power steering system of an outboard motor to be mounted to a body of a hull including a steering bracket secured to the body of the hull, a swivel bracket rotatable about a body of the outboard motor and a pair of clamp brackets supporting the swivel bracket, comprises a manual steering unit for manually steering a steering element to operate the outboard motor, the manual steering unit including a link mechanism connected to the steering element and connected to the steering bracket and a power unit operatively connected to the link mechanism of the manual steering unit. The power unit includes an electric motor for applying a steering asist force to the manual steering unit for reducing steering load during steering operation through the link mechanism and alos includes a mechanism for converting rotation of the electric motor into linear motion. The power steering system may further comprises a clutch means operatively connected to the manual steering unit and the power unit and a control unit for controlling the connection of the power unit so as to be cut out from the manual steering unit. The power unit may be located at a portion outside of the hull in a bracket or in front of the clamp bracket of the outboard motor.
