Description
Technical field
The invention belongs to electric vehicle engineering field, more particularly, relate to the coupling of a kind of major-minor motor and take into account extended-range drive system.
Background technology
Along with the development of society, limited oil resources and problem of environmental pollution become and become increasingly conspicuous, this makes electronlmobil more and more cause the attention of countries in the world government and various circles of society, in electronlmobil kind, the advantage such as pure electric automobile is high with its zero-emission, efficiency, convenient driving, operation is comfortable, energy source is extensive has become the final developing direction of future automobile industry.But, the battery volume that current pure electric automobile loads is large, heavy, price are high, charging duration is long, continuous make mileage short become its bottleneck developed, so there is stroke-increasing electric automobile in recent years, its technology path is the length of getting pure electric vehicle, mend the short of its pure electric vehicle with vehicle-mounted high-energy backup power or generator set, one be reasonable prestowage decrease battery weight, reduce cost; Two is that user can select vehicle according to the traveling radius often used, and expands pure electronic total kilometrage; Three is have oil-fired power generating unit to provide electric energy when minority long-distance running, expands the advantages such as continual mileage.In stroke-increasing electric automobile, load the battery-driven car of generator set, because of its continue to use conventional fuel oil car energy recharge comfort feature, make it have marketable, economic pragmatic feature, receive the favor of industry and the welcome of user, one of mainstream technology direction having become current power development of automobile for this reason.But, increase a set of independently single cylinder generator set, the little meeting of its power makes electrical generator and drive motor often work simultaneously, be difficult to meet vehicle multi-state, high-performance requirement, and noise, vibrations, efficiency, control etc. encounter difficulties, safe reliability is lower, is unfavorable for vehicle drive and travelling comfort; Increase high-power independently generator set, bring difficulty to cost, weight, space, structure, efficiency etc.The technology path analyzing domestic and international extended-range electric vehicle is all increase independently power generating system, lower with Integral automobile optimal control conjugation, is difficult to ensure car load combined efficiency, has limited to extended-range electric vehicle to integrated, intelligent development.For this reason, this case proposes the coupling of a kind of major-minor motor and takes into account extended-range drive system, and this drive system is integrated by suitable height, and the basis of pure electric vehicle before goes a step further again, and taken into account extended-range drive pattern, improve the complex optimum degree of drive system; Can meet the high-performance needs of multi-state, can meet again the needs of the long distance travel of high speed, improve efficiency, save the energy, reduce cost, bring conveniently, the development for battery-driven car proposes a technical strategies.
Summary of the invention
A kind of major-minor motor coupling that the present invention proposes takes into account extended-range drive system, it is characterized in that: adopt two motors, one of them motor is as main drive motor, another electrical motor is except the electrical generator doing distance increasing unit, be coupled with main drive motor and participate in driving work, (under be called for short auxiliary motor), its one end output shaft is connected with driving engine by power-transfer clutch, other end output shaft and main drive motor output shaft staggered relatively, and coaxial line is inserted in the coupler of retarder; When participating in driving, driving engine is separated with secondary electrical motor by power-transfer clutch, coupler simultaneously in retarder combines, and the secondary electrical motor of assistive drive and the power of driver motor realize collecting in retarder coupler, realizes the driving of major-minor motorcoupling and improves vehicles dynamic performance; When vehicle is less to power demand, auxiliary motor can leave unused or go compatible generating, thus expands and continuously make mileage; Become one above assembly machine, under car load network control, single motor individual drive when can obtain high speed, high-power time double-motor couple drive, especially big load time driving engine and extended-range when the combination drive of major-minor motor, energy content of battery deficiency generate electricity and the multiple drive modes such as to drive, facilitate employing intelligent and networked control, ensure that the reasonably optimizing of various drive pattern is selected and switches; Native system comprises: driving engine, power-transfer clutch, secondary driving motor, retarder, driver motor, generator set controller, Double Motor Control device.
Driving engine described in native system takes V-arrangement two cylinder water-cooled four cycle engine, improves power, also possess compartment heating condition with small-sized Zengcheng device driving engine ratio, and its threshold value to be operated at full capacity scope to meet main drive motor; Native system power-transfer clutch ensures connecting and switching smoothly of driving engine and secondary electrical motor; The secondary electrical motor of native system be its power of permagnetic synchronous motor can from main drive that electrical motor is identical also can be different, guarantee to participate in smoothly driving, connect with driving engine when needs increase Cheng Fa electricity, ensure to generate electricity smoothly under generator set controller control; The retarder of native system is the function possessing double-motor couple drive, and its major-minor motor output shaft confronting coaxial line is placed, and is inserted in the coupler of retarder, coupler in conjunction with time the coupler of power in retarder in realize collecting rear drive vehicle and travel; The driver motor of native system is permagnetic synchronous motor, and its power threshold is less about one times than single motor-driven pure electric vehicle driving motor power.
As mentioned above, because secondary electrical motor participates in driving, make main drive motor reduce power, so can improve motor rotations, cover by revolution and can expand retarder speed ratio, thus can Direct driver be taked, deducted gearshift; Because secondary motor power (output) superposes with driver motor power the tractive performance that ensure that vehicle, when increasing under journey pattern as occur large load, secondary electrical motor still participates in the tractive performance driving maintenance excellent instantaneously; Because main drive motor power reduction makes electrical motor be operated between high efficient area, motor own loss reduces to save the energy; Because power of motor decreases motor diameter, facilitate integrated with layout; Due to power of motor reduce electrokinetic cell bus current is reduced, decrease line loss, save the energy expand continue make mileage; Because power of motor reduces, decrease heavy current impact chance and improve battery life.
As mentioned above, single motor individual drive when native system has possessed high speed, high-power time major-minor motorcoupling drive, especially big load time increase journey machine and extended-range when double-motor combination drive, energy content of battery deficiency and generate electricity and the multiple drive modes such as to drive, more adapt to the various working demand of automobile, facilitate intelligentized control method and management, close driveability and in-use performance with exceeding orthodox car, possesses advance and practicality; Due to highly integrated and unified consideration loading space with rationally supports, native system keeps in repair in entire vehicle design layout, manufacture, reduce costs, increase the benefit, facilitate volume production etc. in also all there is the incomparable advance of present battery-driven car; As mentioned above, this technology path is that the industrialization of electronlmobil proposes a Tiao Xin road, has great importance and positive effect to the development of new-energy automobile.
