Marine Control-ship Transmission Control Means Patents (Class 74/DIG8)
  • Patent number: 5312277
    Abstract: A method and a device for power transmission from a motor having a supercharging assembly, particularly a supercharged diesel-engine (7), to a gear (3) with a surface water driving propeller mechanism (4) mounted in a boat of the planing variety and preferably with a large propeller with a large pitch. A turbine coupling (10), which can be filled to a variable extent, is mounted between the supercharged motor (7) and the gear (3). The motor is designed to drive the pump portion (15) of the turbine coupling (10), and the turbine portion (17) of the turbine coupling (10) is connected to the input shaft (6) of the gear (3). The turbine coupling (10), when the boat is started, is emptied completely or partially, in such a way that it is at least partially disconnected from the gear. The motor is then accelerated to such a speed that the supercharging assembly of the motor (7) is connected.

  • Patent number: 5222901
    Abstract: This invention relates in general to an electro-mechanical engine control system configured in such a manner as to provide redundant engine controls for marine engines. Microprocessor based, electronic controlled mechanical servos and an electro-mechanical transferring apparatus, facilitates the integration of the electronic control system with mechanical engine controls as they are known to the marine industry of today. This combination of electronic engine controls, integrated with clutch driven servos and mechanical transferring mechanism provides the operator of any marine craft the ease of operation of electronic controls with the security of mechanical backup operation in case of power or system failure.

  • Patent number: 5056379
    Abstract: A device for the remote control of engine functions comprising two control units, each control unit having a system consisting of an output shaft coupled with a first control potentiometer, a swiveling gear wheel segment which is coupled with the output shaft and which is connected to a push-pull cable the other end of which is connected to an operating lever of the engine, and adjusting motor coupled with the output shaft, an electronic control circuit for the adjusting motor, and a control mechanism connected to each control unit by means of an electric cable which is also connected to the electronic control circuit. The control mechanism has a second control potentiometer coupled to an operating handle, whereby the electronic control circuit compares the electric signals derived from the first and said control potentiometers and energizes the adjusting motors when the difference exceeds a given threshold value.

  • Patent number: 4952181
    Abstract: A shift cable assembly for a marine drive having a clutch and gear assembly (18), includes a remote control (11) for selectively positioning the clutch and gear assembly into forward, neutral and reverse, a control cable (10) connecting the remote control to a shift lever (3) pivotally mounted on a shift plate (2), a drive cable (17) connecting the shift lever on the shift plate to the clutch and gear assembly, and a spring guide assembly (100) with compression springs (101, 102, 103) biased to a loaded condition by movement of the remote control from neutral to forward and also biased to a loaded condition by movement of the remote control from neutral to reverse. The bias minimizes chatter of the clutch and gear assembly upon shifting into gear, and aids shifting out of gear and minimizes slow shifting out of gear and returns the remote control to neutral, all with minimum backlash of the cables.

  • Patent number: 4753618
    Abstract: A shift cable assembly for a marine drive includes a shift plate, a shift lever pivotally mounted on the plate, and a switch actuating arm pivotally mounted on the plate between a first neutral position and a second switch actuating position. A control cable and drive cable interconnect the shift lever and switching actuating arm with a remote control and clutch and gear assembly for the marine drive so that shifting of the remote control by a boat operator moves the cables to pivot the shift lever and switch actuating arm which in turn actuates a shift interrupter switch mounted on the plate to momentarily interrupt ignition of the drive unit to permit easier shifting into forward, neutral and reverse gears. A spring biases the arm into its neutral position and the arm includes an improved mounting for retaining the spring in its proper location on the arm.

  • Patent number: 4683778
    Abstract: In a system for controlling a drive unit, particularly a boat drive unit, which comprises an internal combustion engine and a reversible gearing, with an operating member for adjusting the power and the direction of rotation, the operating member (1) feeds electric signals corresponding to the power and the direction of turning to a control device (5) which contains a microcomputer (6). Actuators (11, 12) for the power of the internal combustion engine and the switching of the reversible gearing respectively are connected to the control device (5). The control device (5) is developed in such a manner that switching of the reversible gearing is only possible when the speed of rotation of the internal combustion engine lies below a predetermined value.

    Abstract: Both gas turbines of a drive system for marine vessels can be selectively connected by related first clutches with drive pinions and during so-called cruising travel, where only one drive unit or machine is operative, additionally via a gearing train with the related drive pinions. By means of speed reduction gearing the drive pinions drive two propeller shafts.

  • Patent number: 4051679
    Abstract: When reversing a marine power plant, due consideration must be given to the fact that the inertia of the ship will continue to force the ship through the water during a moment of time after the shut down of the prime mover, with the propeller then acting as a water turbine tending to rotate the propeller shaft in the same direction as before. If the propulsion plant includes a gas turbine and a reversing gear, the reversing gear is designed in such a manner that the part thereof connected to the turbine will represent, in use, a smaller inertia than the part connected to the propeller shaft, with the propeller shaft together with the propeller attached thereto representing a considerable rotating body.
