摘要： A rotary actuator is used to steer a watercraft with an outboard motor. First and second brackets are attached to the outboard motor and the transom of the watercraft, respectively. The rotary actuator can be a hydraulic rotary actuator and either the rotor portion or stator portion of the rotary actuator can be attached to the outboard motor with the other portion being attached to the transom. A hydraulic pump is used to provide pressurized fluid to the actuator and a valve is used to selectively direct the pressurized fluid to one of two ports in the rotary actuator to select the directional rotation and speed between the stator portion and the rotor portion.

摘要： A remote, electrical steering system for marine vehicles including an electrical motor operable by a control and power circuit to rotate a drive screw having a screw connection to a nut in a drive tube for moving the drive tube in translation to cause steering movement of a motor/rudder with the control circuit sensing various fault conditions for placing the electrical motor in a brake condition to inhibit inadvertent steering and with the screw and nut connection resisting backlash from the motor/rudder to inhibit inadvertent steering and isolate the electrical motor and associated gearing from backlash loads.

摘要： A marine autopilot includes a roll compensation feature to improve autopilot performance. An additional parameter is included in a proportional-integral-derivative control algorithm. The additional term corresponds to the roll angle of the vessel. Since, roll precedes deviation of a vessel from a desired course, the rudder moves to compensate for the disturbance prior to deviation from the desired course. In this way, the vessel's course keeping performance is improved and the overall rudder activity is reduced since the vessel remains more closely aligned with the desired course.

摘要： A power steering system for an outboard motor capable of permitting an electric motor to be driven only when the driving of the electric motor is required and automatically controlling the steering force of a steering wheel depending upon the steering reaction force. The system is so constructed that a steering cable is moved depending upon the rotation of the steering wheel and the movement of the steering cable is detected by means of a steering force sensor, which supplies a signal to a controller. The controller controls the output of the electric motor depending upon the signal.

摘要： Steering mechanism for a boat motor having a shaft which turns to turn the boat motor. A plurality of first contacts is spaced circumferentially around the shaft. A sweep contact mounted on the shaft sequentially engages the first contacts as the shaft turns. A pivotally mounted pedal swings a contact plate. A plurality of second contacts, each of which is connected to a respective one of the first contacts, is engageable with the contact plate. Upon movement of the pedal power is supplied to the steering motor until the sweep contact engages one of the first contacts which is connected to a second contact that is free of the contact plate. The contact plate can include two contact plate portions, one of which is connected in series with the steering motor when the pedal is moved in one direction and the other of which is connected in series with the steering motor when the pedal is moved in an opposite direction. Polarity of the connection to the steering motor is reversed as the connection with contact plate portions is changed to reverse the direction of steering motor advance.

摘要： An electro-hydraulic system especially adapted for the steering of riverboats and the like according to which accurate control is gained in the steering operation. The system includes a variable volume piston pump under the control of a servo controller so as to produce variable rates of fluid flow from the pump to an output steering device which is operative to effectuate precision steering of the vehicle. A steering device position feedback arrangement is provided according to which a signal is fed back, responsive to movement of the steering device, in such a way as to effectively nullify the initiating signal input to the servo controller, thereby to return the pump to a null position at a time when the steering device has assumed the position desired.

摘要： According to at least one embodiment, an electric actuator for a marine steering system is disclosed. The electric actuator includes a housing, an output shaft, a screw assembly coupled to the output shaft, a rotor coupled to the screw assembly, and a motor configured to rotate the rotor. Rotation of the rotor causes the output shaft to translate axially relative to the housing.

摘要： A ship steering device includes a handle which is mechanically separated from a rudder mechanism, a steering angle detecting unit that detects a steering angle of the handle, a reaction force motor that generates reaction force torque to be applied to the handle, and a reaction force controller that controls, based on a steering characteristics map, the reaction force motor in such a way that the reaction force torque in accordance with the steering angle is obtained. The steering characteristics map has characteristics in such a way that the amount of change in an aiming steering torque relative to the steering angle is smaller in a second steering range where the steering angle is larger than that in a first steering range than the first steering region where the steering angle is set in advance from zero.
