Description

A kind of car and boat travel and drive kinetic energy conversion transfer device

Technical field

The utility model belongs to traffic machinery, relates generally to a kind of driving kinetic energy conversion transfer device that uses on car, ship.

Background technology

At present, most automobiles or steamer all with combustion engine as its driving propulsion source that travels, and the high heat energy that produces after the fuel oil detonation of combustion engine drives its bent axle and rotates and become mechanical energy, this mechanical energy directly drives wheel or blade rotates, and car and boat are moved ahead.But, in the car and boat driving process, car and boat advance travel energy that energy needed and combustion engine sent can not be rationally and high efficiency cooperate, produce and cause the partly loss of energy.For example, when automobile travelled with bottom gear, internal-combustion engine rotational speed was still higher, and the wheel uniform rotation, driving kinetic energy required during automobile advances is less than the combustion engine energy output, and power of IC engine has very big waste.Also there is same phenomenon in other gears.Because being rigidity, the automobile of band retaining drives, so combustion engine often is in and does under the negative work state when running car.When the descent run, when gravitional force transformed kinetic energy greater than resistance to motion, combustion engine was made negative work as vehicle, not work done when equating, less than the time work efficiency not high yet; When vehicle moves with economic speed on flat road surface, the load power of combustion engine is generally between the 20-40% of rating horsepower, under this kind state, the combustion engine gas consumption rate is still higher, in other words, because positive drive, internal-combustion engine rotational speed and change speed gear box gear are constant, and the real-world operation resistance does not need current combustion engine horsepower output, and 3000 rev/mins of rotation horsepower outputs have just equaled car resistance such as 4000 rev/mins of combustion engines rotate.Equally, because the positive drive of combustion engine outputting power, when combustion engine was lower than 4000 rev/mins, combustion engine was not make useful work, was adventurous and adopt the ride the clutch method, and navigating mate can produce driving fatigue simultaneously, drove and felt also bad.In addition, infinite variable speed vehicle transmission efficient is low, and fuel economy is poor, and when being in top gear, some road conditions danger is run at high speed as descending, can not keep the horsepower output of combustion engine and energy needed to mate at any time.

Summary of the invention

The purpose of this utility model is exactly problem and the defective that exists at above-mentioned prior art, design provides a kind of car and boat of new construction to travel and drives kinetic energy conversion transfer device, reach and simplify the car and boat drive configuration that travels, rationally use the combustion engine horsepower output, significantly save fuel oil, make things convenient for driver behavior, improve the purpose of safety.

Basic design of the present utility model is, this device by combustion engine, it encourage dynamo generator, series excitation or D.C. compound generator and drive wheels or screw blade be connected in series successively the assembling constitute, its I. C. engine crankshaft clutch end is encouraged the dynamo generator rotating shaft with it and is connected, the lead two ends are fixed in it respectively and encourage on dynamo generator and series excitation or the D.C. compound generator, and the motor shaft of series excitation or D.C. compound generator is connected with drive wheels or screw blade.

The utility model still is the car and boat driving power sources that travel with the combustion engine, adopt combustion engine, it encourages the structure that dynamo generator, series excitation or D.C. compound generator and drive wheels or screw blade are connected in series, the heat energy of fuel oil is converted into successively the mode of mechanical energy, electric energy, mechanical energy, the driving car and boat travel, and its characteristics are as follows: 1, simple, the saving fuel oil of the bassinet structure than existing machinery transmission type.2, good dynamic property, because the horsepower output of driving engine is relevant with the negative work of resistance, there is not the positive drive change-speed box, thereby make propulsive effort on the drive wheel increase power gradually not interrupt, the driving engine energy output is through being that transmission of energy is mended rather than the transmission of power of mechanical rigid after transforming, and starting, acceleration capability, the average ground speed of automobile improved, the maximum speed of automobile also can improve.3, control is simple, stepless change.4, good braking ability is arranged, uniformly braking energy.5, increase the stationarity of safety and car.Need not the operation of clutch operating and manual shift at vehicle starting with when travelling, can make chaufeur concentrate one's energy to note the road traffic situation.6, can realize sliding anywhere or anytime, and can realize not reducing the speed of car or the speed of a motor vehicle is controlled.7, counter-rotating glancing impact front truck wheel load is less than the people, for the people that is not pressed onto the place ahead or thing can allow the wheel plugging, is people or the thing that has arranged the place ahead, and do not roll people or thing.8, combustion engine will obtain prolonging service life, because native system has cut off the positive drive of combustion engine and wheel, therefore just reduce the impact that takes place in the power transmission process and live load to the part infringement of combustion engine and driving system, also just prolonged service life.9, improved the through performance of automobile.Series excitation or D.C. compound generator are the variations that adapts to automobile running resistance voluntarily in the engine power output area, its excitation of encouraging dynamo generator of scalable changes the rotating speed of combustion engine rapidly again where necessary, the energy output of combustion engine changes to satisfy the needs of tractive force, has therefore significantly improved the through performance of automobile.10, reduced exhaust emission.The manual shift process usually has the fuel feeding steep variation, and internal-combustion engine rotational speed changes situation greatly, causes incomplete combustion easily, makes that objectionable impurities increases in the engine exhaust gas.The rotating speed that combustion engine keeps relative stability in native system, the combustion conditions of combustion engine can not worsen, and therefore can reduce the pollution of the waste gas of engine emission to air.11, reduced man-made failure operation and the oil consumption that causes.Combustion engine can not stop working when 12, going up a slope.Because the underproof of automobile or shift gears untimelyly, regular meeting causes flame-out parking and the combustion engine that causes of combustion engine to restart problem, promptly dangerous also oil consumption.

The specific embodiment

Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.A kind of car and boat travel and drive kinetic energy conversion transfer device, this device by combustion engine 1, it encourage dynamo generator 2, series excitation or D.C. compound generator 4 and drive wheels or screw blade 5 be connected in series successively the assembling constitute, its combustion engine 1 bent axle clutch end is encouraged dynamo generator 2 rotating shafts with it and is connected, lead 3 two ends are fixed in it respectively and encourage on dynamo generator 2 and series excitation or the D.C. compound generator 4, and the motor shaft of series excitation or D.C. compound generator 4 is connected with drive wheels or screw blade 5.The bent axle of combustion engine 1 is encouraged with it and can be adopted coupler or universal joint shaft to carry out coaxial mechanical connecting structure between dynamo generator 2 rotating shafts, also can adopt diaxon dislocation physical construction to connect.Adopt universal joint shaft connectivity scenario conventional on the car and boat to get final product between series excitation or D.C. compound generator 4 and drive wheels or the screw blade 5, also can be put into series excitation or D.C. compound generator on the wheel.

With the more four-stroke engine of car and boat adapted is example, and the bent axle driving engine that whenever takes two turns is finished a cycle of operations, and the energy that is sent is relevant with the total displacement of cylinder.At a cycle of operations, set excitation that it encourages dynamo generator to reach the purpose of efficient absorption energy, can rationally adjust the load factor of driving engine, to reach the requirement of engine speed change by changing the excitation size.What cycle of operationss the rotating speed of driving engine just just finishes in the unit time, when being reflected to it and encouraging dynamo generator, it is the respective change of voltage, finish the at any time Conversion of energy of electrical generator to combustion engine, the mechanical specialities of its separately ex-cited generator variation relation hard and series excitation or D.C. compound generator load is little, thus the positive drive of cancellation change-speed box one class.Electrical motor has following characteristics with the mechanical specialities of series excitation or D.C. compound generator: 1, be a nonlinear software feature, 2, when electromagnetic torque hour rotating speed very high, 3, square being directly proportional of electromagnetic torque and electric current, so detent torque is very big, overload capacity is strong.As can derive the wheel reversing braking with wheel and electrical motor one, the logical no power of each wheel may be finished the control to wheel speed, reaches steadily the purpose of control car load rationally.The theoretical basis of setting up is that the electrical generator rotation will produce electric current, and electrical motor has electric current will produce externally acting of rotation, thereby the energy of realizing combustion engine changes into energy needed at any time with high efficiency.Up to now, driving engine does not also appear, it encourages dynamo generator and series excitation or D.C. compound generator, wheel, the direct-connected report that is used and precedent.With the combination of the excitation of the excitation of resistance braking or reversal connection series excitation or D.C. compound generator or resistance braking and reversal connection series excitation DC motor, to reach the purpose of braking.The result who finishes is that the rotating speed of the rotating speed of driving engine and wheel is separated.If the driving engine acting is greater than resistance to motion, automobile will speed up; If the driving engine acting equals resistance to motion, automobile will be kept former form in the past; If the driving engine acting is less than resistance to motion, automobile is with Reduced Speed Now.Thereby improved the useful work of driving engine greatly, avoided the rigid of transmission of driving engine exactly, made engine traction match with car resistance, irrelevant with engine speed, relevant with the horsepower output of driving engine, and realized stepless change, improved driving performance and safety.During from engine starting to maximum speed of revolution, therefore the maximum torque of driving engine and maximum power can not require the excitation size to do respective change according to engine speed, to reach the extraction to driving engine energy output maximum on same rotating speed.

The electrical motor or the electrical generator that can satisfy above condition are not a kind of.Alternating-current motor/AC motor also is gradually improved, and can both use AC speed regulating with the occasion of DC speed regulation such as every.DC speed regulation is inaccessible, as high capacity, and high rotating speed, AC speed regulating can both be used in the place that high potential and environment are very abominable.Also have permanent magnet motor, permanent magnetism mixing brushless motor, switched reluctance motor, universal motor etc., the possibility that reaches corresponding requirements is all arranged.
