440058000 | Having toothed or threaded member to move propulsion unit or a segment of the propulsion unit | 10 |
20100105261 | POWER STEERING APPARATUS OF WATERCRAFT WITH PROPELLER - In a power steering apparatus of a watercraft | 04-29-2010 |
20110117798 | STEERING DEVICE FOR OUTBOARD ENGINE - In a steering device for an outboard engine, a drive shaft of a helm mechanism and an output shaft of an electric assist mechanism are disposed orthogonally to a steering output shaft of a steering operation member. Where the steering operation member is a tiller handle, a torque sensor, provided between an outboard engine body and the tiller handle, detects, as steering torque, a difference between steering angles of the engine body and the tiller handle, and the helm mechanism, drivable by the assist mechanism, operates to compensate for the difference between the steering angles. The assist mechanism and the helm mechanism are provided on the body of the boat. | 05-19-2011 |
20110117799 | STEERING DEVICE FOR OUTBOARD ENGINE - A steering device for an outboard engine includes: a helm mechanism operable, in response to operation of a steering wheel, to steer the outboard engine and including a drive shaft parallel to an output shaft of the operation member; an electric assist mechanism for detecting steering torque, applied to the steering wheel, to assist operation of the helm mechanism on the basis of the detected steering torque; and a power transmission section for connecting the output shaft of the steering wheel and the helm mechanism to transmit rotation of the output shaft to the helm mechanism. | 05-19-2011 |
440059000 | Screw type | 5 |
20080200080 | STEERING SYSTEM FOR OUTBOARD MOTOR - A swivel bracket of an outboard motor pivots about an axis of a tilt shaft disposed at a front end of the bracket unit and extending horizontally in a vertical plane to adjust a tilt angle and a trim angle of the outboard motor. A steering system for the outboard motor includes a pivotal gear attached to the swivel shaft, a drive mechanism driving the pivotal gear, and an electric motor providing drive force to the drive mechanism. Preferably these steering system components are positioned between the swivel bracket and an engine cowling of the outboard motor. | 08-21-2008 |
20100120303 | PROPULSION DEVICE - A propulsion device includes a propulsion device main body, an attachment mechanism, and a steering mechanism. The attachment mechanism is arranged to attach the propulsion device main body to a hull such that the propulsion device main body turns right and left with respect to the hull about a swivel shaft. Further, the attachment mechanism is arranged to attach the propulsion device main body to the hull such that the propulsion device main body turns up and down with respect to the hull about a tilt shaft. The steering mechanism includes a motor and a transmitting mechanism. The transmitting mechanism is arranged to transmit a driving force of the motor to the propulsion device main body to turn the propulsion device main body to the right or the left. The attachment mechanism includes a housing space in which the motor and the transmitting mechanism are housed. | 05-13-2010 |
20100173543 | OUTBOARD MARINE MOTOR THAT ALLOWS A LARGE STEERING ANGLE - In an outboard marine motor including an upper case ( | 07-08-2010 |
20120040572 | STEERING APPARATUS FOR OUTBOARD MOTOR - Support arms are disposed on a tilting shaft on a bracket of an outboard motor. An electric actuator is mounted between the support arms. The electric actuator includes a cover member, first and second electric motors disposed individually on the opposite ends of the cover member, a feed screw configured to be rotated by the electric motors, a nut member configured to move along an axis as the feed screw rotates, a drive arm configured to move integrally with the nut member and transversely relative to the boat body, and protective boots. The drive arm is connected to a steering arm through an engaging member. If the drive arm moves in the direction of the axis along the cover member, the steering angle of the steering arm changes depending on the degree of movement of the drive arm. | 02-16-2012 |
20140113513 | Calibrable Maneuver Control Arrangement for Boats - An arrangement for the maneuver control of a twin-engine boat ( | 04-24-2014 |
440060000 | Rack and pinion | 2 |
20100167604 | OUTBOARD MARINE MOTOR THAT ALLOWS A LARGE STEERING ANGLE - In an outboard marine motor including an upper case ( | 07-01-2010 |
20120094558 | MARINE VESSEL PROPULSION APPARATUS - A marine vessel propulsion apparatus includes a transom bracket, a steering shaft, an outboard motor, a tilt mechanism, and a steering mechanism. The steering shaft is joined to the transom bracket, and is turnable around a steering axis extending in an up-down direction. The outboard motor is joined to the steering shaft, turnable around a tilt axis, and turnable around the steering axis together with the steering shaft. The tilt mechanism is arranged to turn the outboard motor around the tilt axis with respect to the steering shaft. The steering mechanism includes a power conversion mechanism arranged to convert power of the electric motor into turning of the steering shaft around the steering axis. | 04-19-2012 |
