Description
Technical field
The present invention relates to a kind of automotive transmission motor, a kind of specifically electric gear shift(ing) double-rotor machine that is used for hybrid vehicle.
Background technology
Along with holding of the United Nations's meteorological meeting, reduce the emphasis that greenhouse gas emission has become the whole world to pay close attention to, according to statistics; In the discharging of whole world greenhouse gas; Automobile is approximately 14%, is only second to power station (accounting for 21.3%) and industrial processes (16.8%), is listed as the 3rd.The discharging that reduces automobile will become the most important thing of reduction of discharging, with the input that attracts fund with technology more and more.National governments have also strengthened policy support dynamics, the especially Chinese government aspect the automobile reduction of discharging one after another, are constantly putting into effect new preferential policy and are encouraging enterprise's exploitation that the new-energy automobile of emission reduction effect is arranged.New-energy automobile is just with annual 130% speed increment; The new-energy automobile that comprises hybrid power makes orthodox car face a revolutionary variation; It is predicted; By 2015, with hybrid power and pure electronic be that master's new-energy automobile will replace the main flow that automobile powered by conventional energy becomes automobile market.
The hybrid vehicle of formation commodity is representative with general sharp this of Toyota at present, all carries out mechanical couplings through planetary gear, adopts the hybrid vehicle of bi-motor (EVT) to adopt the electric coupling principle; Owing to saved engine flywheel, clutch and gearbox; Make weight lighter, efficient is higher, and is external just in research and development since 80 years of last century; Recent years is domestic also in exploitation, produces but fail so far to finalize the design.Fig. 1 is the structure principle chart of the present Hybrid Vehicle double-rotor machine of researching and developing both at home and abroad; This is a double-rotor machine under the unified magnetic field; Internal rotor 1 has three phase windings with stator 3; Be evenly equipped with permanent magnet inside and outside the external rotor 2, internal rotor 1 is formed first motor (motor promptly) with external rotor 2 inboard permanent magnets, and the permanent magnet in external rotor 2 outsides and stator 3 are formed second motor (promptly outer motor).When engine drives internal rotor 1 rotated, external rotor 2 was also followed rotation under the effect in magnetic field, did not lose if do not consider the magnetic field of causing in the gap of inner and outer rotors, and output torque on the external rotor 2 and the engine input torque on internal rotor equates.External rotor output shaft 4 connects automobile driving system, and there is speed discrepancy in internal rotor power shaft 5 sending and receiving motivations between the inner and outer rotors under the general operating mode, if engine speed greater than drive shaft speed, interior motor just becomes generator.The power output of engine is divided into two parts, and a part directly is penetrated into the driving shaft of automobile through magnetic induction, and another part converts electric energy to through generator.The alternating current that generator sends can be to battery charge through over commutation; Also can convert alternating current to and link to each other through straight/interchange again with stator winding; As the driving power of second motor (promptly outer motor), when the power that penetrates of first motor is replenished by second motor can not satisfy the needs of vehicle behavior the time.Second motor can be when engine shutdown battery-powered direct driving automobile.Same principle, when the rotating speed of driving shaft greater than engine speed or drive shaft torque when penetrating moment of torsion, second motor also can be as generator, to battery charge.The same with present most popular hybrid vehicle, two motors all can be accomplished the conversion of mechanical energy-electric energy-mechanical or electrical energy-mechanical energy-electric energy, and just coupled modes are through electric coupling rather than through the planetary gear coupling.
Can find out that from the structure principle chart of Fig. 1 in order to reduce magnetic loss, the gap between internal rotor 1 and the external rotor 2 must be as far as possible little; Be generally less than 1mm; Therefore, maximum technical barrier is exactly the coil heating cooling problem of internal rotor 1, owing to be rotating shaft; Can not be cooled with circulating water, use air-cooled enough airflow spaces that do not have again.And the work of the winding of internal rotor 1 time generally is under the situation of long-time big electric current (load), and heating problem is more outstanding, has exceeded the tolerance range of enamelled wire commonly used.Existing for a long time to the research and development of double-rotor machine both at home and abroad, but do not form industrialization all the time, it is one of major reason that the cooling problem does not break through.
