摘要:
A transmission for a human-powered vehicle. The transmission has a primary system that includes a transmission case, a crankshaft with cog, a pair of receiver cranks, a pair of connecting rods, a pair of oscillating driver cranks, and a pair of pedals. A secondary biasing system is engaged with the primary system to provide a favorable torque around dead centers of the primary system. The transmission 150 may be configured to transmit power by driveshaft, chain, or belt to drive a wheel or propeller. In a watercraft application, an operator alternatingly applies force to a pair of pedals while seated close to the floor of a kayak 145. Power from the transmission is transmitted through a steerable lower gear case 134 via a propeller to propel the craft. The operator maneuvers the craft by means of a control lever 135 operably connected to the lower gear case by cables 136.

A boat capable of assigning device instance numbers in accordance with the placement order of boat propulsion units, irrespective of the activation order of the boat propulsion units, comprises a plurality of control units for controlling a plurality of boat propulsion units. A plurality of gauge sections for displaying operation information of the respective boat propulsion units are connected to each other and to the plurality of control units via a communication network. The respective control units assign device instance numbers to the operation information of the boat propulsion units and transmit the device instance numbers, and the respective gauge sections identify and receive the device instance numbers for display. The control units are connected to each other via a communication line, and respectively include DI-number setting sections capable of setting device instance numbers, and determining sections capable of determining the positions of the boat propulsion units. The DI-number setting sections are adapted to set device instance numbers based on the number of the control units, and the positions of the boat propulsion units.

A propulsion system and power plant for boats, preferably for naval vessels, consisting of two Diesel engines, a gas turbine and two drive shafts located next to one another with propellers, is characterized by the fact that there is also a water jet or hydrojet propulsion unit (1) between the two drive shafts (2, 3) which are located next to one another with propellers (4, 5), that the Diesel engines (6,7) are used to drive the two propellers (4, 5), that the water jet propulsion (1) is provided by the gas turbine (8) and that the gas turbine (8) is located between the Diesel engines (6, 7) and the stern of the vessel (9).
摘要:
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.

摘要:
A method for controlling the hybrid drive system of a water craft, comprising a combustion engine (1), an electric engine/generator (2), a drive train (5) having a propeller (7) and a storage battery (3), a control unit (8) and a clutch (4). In order to increase efficiency, during travel in the upper power range the electric engine (2) is additionally operated as a generator, and during travel in the middle and lower power ranges the electric engine (2) is operated with current from a storage battery (3). The drive train is designed so that the characteristic (20) thereof lies by a defined charging capacity below the point of minimum specific fuel consumption (e.g. 25), or is steeper than the characteristic (16) of a conventional construction.
