Embodiment
Refer to Fig. 3, this is the embodiment of the application for the synchronous machine of stroke-increasing electric automobile.Housing 201 has crossed an inner chamber, is provided with external rotor 202, the first stator 203, the second stator 204 and internal rotor 205 in this inner chamber.Described housing is for example casting aluminium material.The first stator 203 and the second stator 204 are fixed on housing 201 by set bolt 208.The first stator 203 surrounds the second stator 204, and has certain interval between the two, and cooling water channel 210 is just arranged in this gap.External rotor is arranged on the periphery of the first stator 203 rotationally, and this is a permanent magnet element.Internal rotor 205 is arranged on the inside of the second stator 204 rotationally, and this is an electric exciting part.Motor power shaft 206 is fixed on housing 201 rotationally by bearing 207, and motor output shaft 211 is also fixed on housing 201 rotationally by bearing 207.Bearing 207 is for example ball deep groove ball bearing.Hall element 209 is arranged on external rotor 202 or motor output shaft 211 or both joint portions.Preferably, for example, at the multiple Hall elements 209 of the interior placement of housing 201, more than three, to improve accuracy of detection.
Wherein, motor power shaft 206, internal rotor 205 and the second stator 204 main compositions generator, this is an electric excitation synchronous motor.Described the second stator 204 comprises again the second stator core and interior winding.Motor power shaft 206 is directly connected with the output shaft (bent axle) of internal combustion engine.Because generator diameter is less, adopt electric excitation design can effectively avoid the defect that permanent magnetic steel utilance is lower.In stroke-increasing electric automobile, generator is work in the time of the electric weight deficiency of high-tension battery only, and working point is comparatively single, therefore adopts lower-cost electric excitation type to be designed to preferably in addition.
Wherein, the first stator 203, external rotor 202 and motor output shaft 211 main compositions drive motors, this is an internal permanent magnet synchronous motor.Described the first stator 203 comprises again the first stator core and outer winding.Motor output shaft 211 is connected with decelerator.
Further, between housing 201, motor power shaft 206 and bearing 207, adopt oil sealing design.Similarly, between housing 201, motor output shaft 211 and bearing 207, also adopt oil sealing design.Like this by lubricating oil or heat radiation oil seal in whole synchronous machine inside, inner and outer Rotator drives fluid to splash while rotation, can carry out inner and outer Rotator coolingly, improves the duration performance of motor.
Refer to Fig. 4 and Fig. 5, the dynamical system of the application's stroke-increasing electric automobile comprises that internal combustion engine 101, synchronous machine 200(are as shown in Figure 3), Double Motor Control device 104, high-tension battery 105, decelerator 106, fuel tank 107.In synchronous machine 200, include generator module and drive motors module.Double Motor Control device 104 also can change two independently electric machine controllers into.
Stroke-increasing electric automobile has two kinds of mode of operations, is respectively electric-only mode, increasing journey pattern.
Refer to Fig. 4, in the time that the electric weight of high-tension battery 105 is higher, obtain energy by Double Motor Control device 104 from high-tension battery 105, by the drive motors module outputting power in synchronous machine 200, be passed to driving wheel through decelerator 106, drive vehicle to move ahead.Here it is electric-only mode.Now internal combustion engine 101 is flame-out, and fuel tank 107 intermediate fuel oil amounts remain unchanged, and the generator module in synchronous machine 200 is not worked.
Refer to Fig. 5, in the time that the electric weight of high-tension battery 105 is lower, first obtain energy by Double Motor Control device 104 from high-tension battery 105 by the generator module in synchronous machine 200, export in short-term high pulling torque (being for example greater than 150Nm) with cranking internal combustion engine 101.Internal combustion engine 101 obtains energy by the fuel oil in burning fuel tank 107 subsequently, and drives the generator module operation in synchronous machine 200.Generator module in synchronous machine 200 charges to high-tension battery 105 by Double Motor Control device 104.Double Motor Control device 104 still obtains energy from high-tension battery 105, by the drive motors module outputting power in synchronous machine 200, is passed to driving wheel through decelerator 106, drives vehicle to move ahead.So just, can maintain the continuous firing of drive motors 103.Here it is increases journey pattern.
For stroke-increasing electric automobile, the output shaft of internal combustion engine 101 is not participated in car load directly and is driven, the charging during only for high-tension battery 105 electric weight deficiency.Therefore in the time that electric-only mode switches to increasing journey pattern, do not have torque ripple, car load ride comfort is guaranteed.
The application has the following advantages for the synchronous machine tool of stroke-increasing electric automobile:
One, the power of generator is little, adopts inner rotor motor; The power of drive motors is large, adopts external rotor electric machine.The stereochemical structure that this drive motors surrounds generator is effectively controlled the axial length of whole synchronous machine.For the horizontal internal combustion engine of current main flow, the dynamical system of horizontal decelerator, horizontal space in enging cabin is required to reduce, thereby can deposit and comprise generator and drive motors at interior synchronous machine at limited car load front deck space lining, compact conformation, flexible arrangement is high.The rear deck of car load can be all for placing high-tension battery group like this, thereby less change car load chassis, suspension etc.
Its two, in the gap between the stator (the first stator 203) of drive motors and the stator (the second stator 204) of generator, cooling water channel 210 is set.Can adopt like this water-cooling pattern to dispel the heat to both, can significantly reduce by two stator temperatures, improve peak value fan-out capability and the duration of drive motors and generator.Also retain oil cooling design simultaneously, by the mode of splashing, the rotor of drive motors and generator has been carried out coolingly, further improved the continuous output of drive motors and generator.
Its three, due to the obstruct of cooling water channel 210, avoided two motor winding magnetic linkages to intercouple, interfere.Due to the generator in synchronous machine 200 and drive motors decoupling zero, make the output load of internal combustion engine 101 less, and working point comparatively single (for example 80Nm, 2500rpm), therefore can adopt small displacement internal combustion engine (as three cylinder machines), to reduce to a greater degree oil consumption and discharge.
Its four, generator and drive motors can share a stator mould, have improved the stock utilization of silicon steel sheet.
Its five, generator has adopted electric excitation synchronous motor, without thulium permanent magnet, provides cost savings.
Its six, drive motors adopts the design of external rotor built-in magnet steel, with respect to surface-mount type design, its higher grade of vibration resistance, and with respect to internal rotor design, its rotor pack reinforcing rib design difficulty is lower, when high-speed cruising, can bear larger centrifugal force.The external diameter of drive motors is larger compared with generator, adopts external-rotor-type design in the circumference of external rotor, to deposit more magnet steel by cloth, promotes the torque/power density of drive motors.
Its seven, adopt Hall element 209 to detect the real time position of the external rotor 202 in external rotor electric machine.For example adopt the design of three transducers of a gear ring cooperation, with respect to external rotor resolver, the technology maturation of Hall element, more easily realization, and cost is lower.
These are only the application's preferred embodiment, and be not used in restriction the application.For a person skilled in the art, the application can have various modifications and variations.All within the application's spirit and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in the application's protection range.
