Auto industry is the mark of modern industry, it it is the leading industry of the national economic development, various aspects in the life of industrial and agricultural production, transportation and human being's production all play indispensable effect, the vacuum pump of vacuum servo energy and electromotor is provided to be arranged on car independently of one another to drive for automobile brake system at present, not only occupy space but also increase cost, the electromotor adopted, ubiquity the phenomenon of low speed illuminating effect difference, and output is little, it is impossible to meet user's instructions for use.Patent of invention such as Chinese patent publication bulletin on January 10th, 2007: hybrid excitation voltage-stabilizing generator, application number: 200510044103.9, it is made up of rotor, stator, drive end bearing bracket, rear end cap, electronic controller, rotating shaft is provided with p-m rotor and electricity excitation rotor, p-m rotor and electricity excitation rotor share same armature winding, and the magnetic flux of generation is in magnetic circuit and is unified into;P-m rotor is cutting orientation structure, by pole shoe rotor core, form every magnetic lining, non-magnetic slot wedge and permanent magnet material, permanent magnet material is sequentially arranged in the groove of pole shoe rotor core by the mode that the polar surface that tangential direction and adjacent permanent magnet material are identical is relative, and fix with non-magnetic slot wedge, pole shoe rotor core is fixed on magnetic lining, every magnetic bushing press-mounting in rotating shaft;Electricity excitation rotor is salient-pole structure, it is made up of field spider iron core and electricity Exciting Windings for Transverse Differential Protection, the number of salient poles of field spider iron core is equal with the number of poles of tangential permanent magnetic rotor, and all it is uniformly distributed along circle, corresponding one by one, the polarity that electricity Exciting Windings for Transverse Differential Protection produces by the convex surface of salient pole after passing into unidirectional current is N pole, the coiling successively of rule separately of S pole, and the number of turn on each salient pole should be equal;Electricity Exciting Windings for Transverse Differential Protection is connected with electronic controller by carbon brush, slip ring.This hybrid excitation voltage-stabilizing generator structure is complicated, and cost is high, and its serviceability needs further improvement.
Summary of the invention
It is an object of the invention to provide one and can overcome drawbacks described above, compact conformation, easy for installation, take up space little, the electrical equipment that can give automobile provides electric energy, can provide the radial direction with vacuum pump of vacuum servo energy and tangential combined magnetic pole generator for brake system again, and its technology contents is:
Radial direction with vacuum pump is made up of vacuum pump, drive end bearing bracket, rear end cap, rotor, stator with tangential combined magnetic pole generator, it is characterized in that: vacuum pump is bolted on commutator end bearing support bracket, generator amature is radial direction and tangential combination type magnetic pole p-m rotor;
nullRadially with tangential combination type magnetic pole p-m rotor by axle、First rectangle permanent-magnet steel、Second rectangle permanent-magnet steel、Rotor core、Peariform slot forms every magnetic air gap,Rotor core is evenly equipped with even number and runs through the first rectangular channel of rotor core thickness,First rectangular channel is radial structure,Do not connect between outer end and the cylindrical of rotor core of the first rectangular channel,Rotor core thickness and the inverted "eight" shape groove formed by two the second rectangular channels it is provided with through in the middle of the outer end of adjacent two the first rectangular channels,Do not connect between outer end and the cylindrical of rotor core of the second rectangular channel,The inner of two the second rectangular channels forming inverted "eight" shape does not connect,It is provided with through the peariform slot of rotor core thickness every magnetic air gap in the inner of each first rectangular channel,Peariform slot connects with the inner of the first rectangular channel every the outer end of magnetic air gap,Adjacent peariform slot does not connect every magnetic air gap,First rectangle permanent-magnet steel is extremely relative with N according to the N pole of adjacent two panels the first rectangle permanent-magnet steel、The S pole mode extremely relative with S is sequentially arranged in the first rectangular channel,Again the second rectangle permanent-magnet steel is sequentially arranged in the second rectangular channel by the mode that the polarity of outer surface is identical with the polarity that adjacent two panels the first rectangle permanent-magnet steel is formed,Rotor core is fitted on axle.
Operation principle: automobile engine drive electrical generators pulley rotation, namely rotor field rotates, armature winding cutting magnetic line, produces electromotive force, provides electric energy for automobile electrical equipment.
The present invention is compared with prior art, rectangle permanent-magnet steel is embedded in the first rectangular channel and second rectangular channel of rotor core respectively, the each magnetic pole and magnetic field of generator amature is provided by four permanent-magnet steels, magnetic field intensity is big, power density is high, and it is few without electricity Exciting Windings for Transverse Differential Protection, power consumption, there is no carbon brush and mechanical commutator, failure rate is low, there is the features such as high efficiency, high power density, compact conformation, provide electric energy, vacuum servo energy can be provided for brake system again to the electrical equipment of automobile.
