Description
Technical field
The present invention relates to a kind of power system of boats and ships, particularly a kind of carry double dynamical ship power system with and How It Works.
Background technology
Along with the increase of mankind's activity, no matter be in transportation, tourism or commercial affairs, significantly improve for the demand of transport facility, thereby brought huge energy resource consumption and environmental pollution.In view of this, the mankind begin to research and develop the power system that has more efficient, in the hope of using still less fuel driven transport facility to farther distance.With present technology, power system takes electrical motor (such as electro-motor) or combustion engine (such as Diesel Engine) as the propulsion source of outputting power more.The characteristic of electrical motor is can have under the slow speed of revolution performance of goodish torsion, simultaneously can discharging waste gas in running, and the noise of generation is also very little, if the electric power that can use the power plant to produce, energy prices are cheap, the pollution that electrogenesis causes is also less.And internal combustion engine development is with a long history, and correlation technique is ripe, therefore has the fiduciary level height, is difficult for fault and advantage with low cost.
But this two still have shortcoming, electrical motor must carry the battery of supplying with its power supply when using simultaneously, movability is subject to limit, even because provide the battery of motor power large and heavy, increases unnecessary heavy burden, has increased on the contrary the consumption of the energy.And the combustion engine of use fossil fuel, inevasible meeting discharging waste gas.More seriously, even if use at present most advanced science and technology, the transformation of energy that combustion engine includes fuel becomes the efficient of power still only to have 30%, and most energy all overflows loose in environment with the form of used heat, noise.
And when these two is loaded in land conveying tools, also can produce other problems.General land conveying tools is such as automobile, locomotive, can run into multi-form road conditions in use, the speed, the torsion that need are ever-changing, under this situation, combustion engine or electrical motor must carry out power output under various rotating speeds, the designer can't be optimized for specific rotation speeds, also can't guarantee during use in the interval running of the optimum speed of design, so can consume unnecessary fuel, further reduce running efficiency.
Therefore people develop the transport facility that carries two kinds of power systems, with the power output mixing of two kinds of power systems, and then the hybrid power system of driving transport facility.Under the situation of low speed, mainly by the electrical motor outputting power of high torsion, under situation at a high speed, mainly by the combustion engine outputting power, with the time combustion engine battery is charged, and the allocation proportion of power output is transferred to the judgement of driving computing machine.No matter thus in the face of any road conditions, can allow electrical motor and combustion engine in the optimum speed of setting separately, work.Rotating speed when having determined running is interval, and the designer more can be optimized electrical motor or combustion engine for this rotating speed environment, further promotes running efficiency, reduces environmental pollution.
Hybrid power system seems the problem of having solved, but produces new shortcoming.The oil pressure that the power-transfer clutch function that general known change speed gear box has must rely on the inputting shaft rotation of change speed gear box to provide starts energy and operates, when using general combustion engine, can lean on its lazy speed to supply with oil pressure and start energy, if but use electrical motor, but can be for utilizing without lazy speed, known change speed gear box thereby can't operate.Therefore in power mixes process with output, must use complicated transmission and gear shift device, so that maintenance and maintenance are difficult for, the whole system price is also quite expensive.And two kinds of power are when mixing output, powershift with mixes between cause easily sluggishness, the transport facility generation is jolted, the passenger experiences discomfort, the danger of driving has also increased.
The advantage of hybrid power system maximum is and can changes the export ratio of two kinds of power systems according to different road conditions, reaches good operational paradigm.But these advantages are lack scope for their abilities when navigating by water on the water, land conveying tools needs larger torsion when starting, and the middle meeting of travelling changes speed because of traffic (traffic congestion, traffic sign), perhaps loiter and repeatedly carry out starting-up action, can cause again needed rotating speed to change when running into uphill/downhill, therefore known hybrid power system is played a role.But during water sailing, traffic is stable, the needed thrust that drives boats and ships is directly proportional with the cube of its speed merely, add that again the density of liquid is far above air, therefore be equal to forever all in climbing compared to the land conveying tools operation situation, and almost can both advance with a fixing speed in the whole voyage of boats and ships, this moment known hybrid power system advantage thereby can't bring into play.And boats and ships single duration of voyage is compared the many of land conveying tools length, in the navigation way, be difficult to carry out supply, so highlighted on the contrary that known hybrid power system causes whole power system complex structure and so that the shortcoming of maintenance difficulty is unfavorable for use waterborne more.
