Hydrokinetic fluid turbines utilize a flowing body of liquid to translate the kinetic energy of the fluid into electric power or other useful energy. The available kinetic energy is proportional to the squared fluid velocity in an open channel with a fixed cross-sectional area. The proposed twin turbine system coupled with a cycloidal magnetic gear exploits the hydrokinetic energy existing in open-channels.

Hydrokinetic turbine system

A cycloidal magnetic gear system for a turbine system is disclosed. The system includes a first stator magnet ring, a second stator magnet ring positioned opposite the first stator magnet ring, and a rotor positioned between the first and second stator rings of magnets. The rotor may include a first side positioned adjacent the first stator magnet ring, and a second side positioned adjacent the second stator magnet ring. The system may include a first rotor magnet ring affixed to the first side of the rotor, adjacent the first stator magnet ring. Additionally, the system may include a second rotor magnet ring affixed to the second side of the rotor, adjacent the second stator magnet ring. The rotor may be configured to rotate eccentrically about a center-axis of the first and/or second stator magnet ring.

Transmission systems and methods are for a marine propulsion device having an internal combustion engine that drives a propulsor. An input shaft is driven into rotation at a non-zero first rotational speed by the internal combustion engine. An output shaft drives the propulsor into rotation at a non-zero second rotational speed. A planetary gearset transfers power from the input shaft to the output shaft. A band brake is on the planetary gearset. Actuation of the band brake effects a gear change in the planetary gearset. A band brake actuator actuates the band brake to effect the gear change. A controller controls the band brake actuator. Based upon one or more operational characteristics of the marine propulsion device the controller is programmed to control the band brake actuator so that the second rotational speed is less than the first rotational speed.

Systems and methods for controlling planetary transmission arrangements for marine propulsion devices

A marine transmission includes a synchronizer on a counter rotating shaft to shift into a high speed gear. The synchronizer includes friction surfaces on both sides of the gear body for the high speed gear. The high speed gear mesh is helical and generates axial force that enhances the torque carrying capacity of synchronizing friction surfaces, thereby enabling the shifting into the high speed gear without torque interrupt.

A band brake actuator is for actuating a band brake on a planetary gearset. The band brake actuator comprises a actuator shaft; an output finger; and a linkage assembly. The linkage assembly connects the actuator shaft to the output finger such that rotation of the actuator shaft in a first rotation direction causes the output finger to engage the band brake on the planetary gearset, and such that rotation of the actuator shaft in an opposite, second rotation direction causes the output finger to disengage the band brake from the planetary gearset. Engagement of the band brake and the planetary gearset shifts the planetary gearset into one of a forward and a reverse gear and wherein disengagement of the band brake and the planetary gearset shifts the planetary gearset into a neutral gear.

A dual clutch transmission (DCT) with double-range change. In one embodiment, the dual clutch transmission includes odd and even lay shafts and a separate range change shaft for each, thereby providing a range change for both the odd and even gear sets. The input shaft may include an extension gear that can be selectively driven by the inner input shaft or the outer input shaft to provide additional gear pairings. The extension gear may include a synchronizer on each face to allow it to be coupled to either the outer or inner input shaft. The transmission may include a reverse shaft coupled with the even lay shaft. The transmission may include a dual half synchronizer having a single hub and a split sleeve. The parts of the split sleeve are separately movable to allow independent synchronization of two pairs of rotating components.

The kinematic arrangement of a multiple-speed automatic transmission for an automotive vehicle includes three simple planetary units, hydraulically actuated clutches and brakes applied and released selectively, and several overrunning couplings that produce one-way drive connection between the inner and outer races, which are connected to various components of the gear units. Each of the planetary gear units includes a sun gear, a ring gear surrounding the sun gear, a carrier, and a set of planet pinions in continuous meshing engagement with the sun gear and ring gear and rotatably supported on the carrier. At least one of the gear units includes an overrunning clutch that produces a one-way drive connection between its carrier and one of the planet pinions supported on the carrier.

A valve (36) for controlling pressure supplied to a friction clutch (32) of an automatic transmission includes several valve spools (38,40,44) each formed with control lands located within a bore (42) opening to various ports (60,66,68,72,76,80) that are supplied selectively with line pressure depending upon the operating state of the transmission. The valve operates in a primed condition, whereby a predetermined low pressure is supplied continually to the friction clutch. The valve supplies the clutch with a higher pressure that operates to stroke the clutch cylinder and friction element and thereafter regulates clutch pressure in accordance with changes in pressure in one of the ports. The clutch is stroked rapidly because the valve provides a relatively unrestricted supply of pressurized fluid through one of its inlet ports. After the clutch free-pack clearances are taken up, the valve restricts the clutch stroke against a cushion spring by opening the clutch cylinder to an orificed supply circuit. A delayed response to a change in operating state of the valve is minimized such that the control lands of the valve spools do not fully open line pressure supplied to the valve.
