Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is further described.
It is illustrated in figure 1 a kind of stroke-increasing electric automobile stator permanent magnetic type double-mechanical-port motor, (can including housing 9 Use casting aluminium material), motor power shaft 6, motor output shaft 5 and be arranged on the internal rotor 4 within housing 9, forever Magnetic-type inner stator 2, motor retainer ring 7, permanent-magnet type external stator 1 and outer rotor 3, and internal rotor 4, permanent-magnet type inner stator 2, motor retainer ring 7, permanent-magnet type external stator 1 and outer rotor 3 are coaxially set from the inside to the outside;Motor retainer ring 7 is not Magnetic conductive metal material;Motor power shaft 6 right-hand member is positioned at housing 9, left end stretches out housing 9, motor output shaft 5 left end Be positioned at housing 9, right-hand member stretches out housing 9;Internal rotor 4 is fixed, in permanent-magnet type with motor power shaft 6 right-hand member coaxial line Stator 2 motor retainer ring 7 inner surface of fitting is fixed, and permanent-magnet type external stator 1 motor retainer ring 7 outer surface of fitting is fixed, Outer rotor 3 is fixed with motor output shaft 5 (crankshaft structure) left end coaxial line.
Described motor power shaft 6, internal rotor 4 and permanent-magnet type inner stator 2 constitute motor in an internal rotor stator permanent magnetic type, claim Be electromotor 11 for this;Owing to electromotor 11 diameter is less, therefore the design of this case can be effectively improved motor output shaft 5 Output, increase operational efficiency.
Described permanent-magnet type external stator 1, outer rotor 3 and motor output shaft 5 constitute the outer motor of an outer rotor stator permanent-magnet type, claim For this be drive motor 12;Owing to driving motor 12 to have the characteristic of low speed high torque, can directly drive automobile, no Need reduction gearing.
The permanent magnet of described electromotor 11 and armature winding are arranged on permanent-magnet type inner stator 2, and internal rotor 4 is by pure silicon steel disc Circumference is overrided to form;Drive the permanent magnet of motor 12 and armature winding to be arranged on permanent-magnet type external stator 1, outer rotor 3 by Pure silicon steel disc circumference is overrided to form.In this case, permanent-magnet type inner stator 2 is consistent with the stator type of permanent-magnet type external stator 1, all For flux switch motor stator, doubly salient permanent magnet motor stator or flux-reversal type motor stator.Preferably, motor retainer ring 7 On be provided with heat radiation duct 8, heat radiation duct 8 can external cooling equipment.
Further, between housing 9, motor power shaft 6, stem seal design is used.Similarly, at housing 9, motor It is also adopted by stem seal design between output shaft 5.So by lubricating oil or heat radiation oil seal inside whole synchronous motor, interior, Drive fluid to splash when outer rotor rotates, inner and outer Rotator can be cooled down, improve the duration performance of motor.
As shown in Figures 2 and 3, include for a kind of stroke-increasing electric automobile power assembly system: internal combustion engine 10, by permanent magnetism Electromotor 11 (as shown in Figure 1) that type inner stator 2, internal rotor 4 and motor power shaft 6 are constituted, by fixed outside permanent-magnet type Driving motor 12 (as shown in Figure 1) that son 1, outer rotor 3 and motor output shaft 5 are constituted, Double Motor Control device 13, Accumulator 14, differential mechanism 15.Double Motor Control device 13 can also change two independent electric machine controllers into.
Stroke-increasing electric automobile has two kinds of mode of operations, is electric-only mode respectively, increases journey pattern.
Refering to Fig. 2, when the electricity of accumulator 14 is higher, Double Motor Control device 13 obtain energy from accumulator 14, By driving motor 12 to export power, it is transferred directly to wheel differential 15, drives vehicle forward.Here it is it is pure electronic Pattern.Now internal combustion engine 10 stops working, and electromotor 11 does not works.
Refering to Fig. 3, when the electricity of accumulator 14 is relatively low, first passed through Double Motor Control device 13 from electric power storage by electromotor 11 Chi14Chu obtains energy, exports high pulling torque in short-term and, to start internal combustion engine 10, and drives internal combustion engine to best operating point and turn Speed.Subsequently, internal combustion engine 10 ignition operation, and drive electromotor 11 to run.Electromotor 11 is by Double Motor Control device 13 charge to accumulator 14.Double Motor Control device 13 still obtains energy at accumulator 14, by driving motor 12 Output power, is transferred directly to wheel differential 15, drives vehicle forward.The most just can maintain and drive motor 12 Continuous firing.Here it is increase journey pattern.
For stroke-increasing electric automobile, the output shaft of internal combustion engine 10 the most directly participates in car load and drives, and is only used for electric power storage Charge during the electricity deficiency of pond 14.Therefore, when electric-only mode switches to and increases journey pattern, there is not torque ripple, car load Ride comfort is guaranteed.
The application stroke-increasing electric automobile stator permanent magnetic type electric has the advantage that
One, significantly reduces volume, saves space in engine compartment.Inside and outside motor is concentric type distribution, this structure The axial length enabling to whole stator permanent magnetic type double-mechanical-port motor is greatly reduced.Horizontal stroke for current main flow For putting the dynamical system of internal combustion engine, horizontal decelerator, require to reduce to the horizontal space in engine compartment, thus can be Arrange in limited car load front deck include electromotor and drive the stator permanent magnetic type double-mechanical-port motor including motor, structure Compact, flexible arrangement is high.
Its two, electromotor and driving couples without magnetic field between motor, controls simply.Between electromotor and driving motor completely Decoupling, can be considered the motor of two platform independent, therefore, can be separately controlled, reduce control complexity.Simultaneously as send out Motor and drive between motor noiseless, internal combustion engine 10 can long-term stable operation at single operating point (such as optimal fuel oil Point), thus small displacement internal combustion engine (such as triplex machine) can be used, to reduce oil consumption and discharge more.
Its three, permanent magnet is arranged on stator, it is to avoid when motor runs, rotor rotates the vibrations brought, and is prevented effectively from The risk of permanent magnet loss of excitation because of vibrations, improves the overall shock resistance of motor and reliability.
Its four, motor retainer ring has louvre, motor retainer ring directly with determining of armature winding and permanent magnet is installed Son contact.By louvre external connection radiating device, can effectively take away motor heat, the performance of motor the most not appointed simultaneously What impact, thus improve the heat dispersion that motor is overall.
Its five, stator permanent magnetic type external rotor electric machine has the characteristic of low speed high torque, can directly be connected with wheel differential, Need not reduction gearing, thus reduce the complexity of cost and system, add system reliability.
Its six, inside and outside rotor is all silicon steel plate stacking and forms, without any winding and permanent magnet, add turn Sub-firmness degree, improves reliability.
Its seven, stator permanent magnetic type double-mechanical-port motor is not required to brush and slip ring, reduces system loss and maintenance cost, Add system reliability.
The above is only the preferred embodiment of the present invention, it should be pointed out that: for those skilled in the art For, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications are also Should be regarded as protection scope of the present invention.
