See also the structure cutaway view of an embodiment of Fig. 1 electromagnetic compatibility structure provided by the invention.
This embodiment be employed in automobile-used have on the existing rotor assembly structure of brush alternating current generator increase by ring-type equipotential parts, i.e. the 3rd slip ring is to realize generator rotor shaft and the equipotential purpose of generator negative pole.
As shown in Figure 1 the 3rd slip ring 1 is press-fited on rotor shaft for alternator 2, and on brush assembly of electric 3, increase third brush 4 and be used, simultaneously with third brush lead-in wire 5 and generator negative pole (housing) welding with the 3rd slip ring 1.The 3rd slip ring 1 selects the material of conduction to process, and preferable selection metal material is processed.
Said the 3rd slip ring 1 (being on the rotary body) and generator housing (fixed structure) adopt and first slip ring, connected mode that second slip ring is identical, promptly form effective connection through brush.Different with original collector ring structure is that the 3rd slip ring is an electric conducting material, directly press-fit on armature spindle, and the employing of former collector ring structure is and the axle insulating Design.So this moment, the 3rd slip ring directly linked to each other with axle, and through the third brush that equates with the generator body bulk potential generator shaft and housing had been carried out the equipotential processing, was electrically connected thereby realize having brush generator rotating parts to reach effective with on-rotatably moving part.
The present invention is not limited to above-mentioned execution mode for the installation site of the 3rd slip ring; That is, the 3rd slip ring 1 as shown in Figure 1 is arranged at a side of first slip ring, also can be arranged between the side or first slip ring and second slip ring of second slip ring; That is to say; The 3rd slip ring 1 can be arranged at the optional position of slip ring assembly 12, is used with the 3rd slip ring 1 owing to will satisfy third brush 4, so; No matter where the 3rd slip ring 1 is arranged at, third brush 4 all is arranged at corresponding with it position.
It is the execution mode that is wholely set that the installation site of the present invention's the 3rd slip ring 1 also is not limited to above-mentioned being arranged on the slip ring assembly 12 with said slip ring assembly; Also can said the 3rd slip ring 1 be arranged at outside the said slip ring assembly 12 and said slip ring assembly split setting; Promptly; Said the 3rd slip ring 1 is placed any position of whole armature spindle; All can realize rotating parts and fixed part housing or the equipotential purpose of negative pole, corresponding said third brush 4 also is arranged at outside the said brush assembly of electric 3 and said brush assembly of electric split setting, and it is corresponding with said the 3rd slip ring 1 to satisfy said third brush 4.
The connected mode of said the 3rd slip ring 1 and generator rotor shaft, not only can adopt press-fit, inlay, modes such as welding, stickup are fixed on the armature spindle, also can directly on armature spindle, process, and do not do concrete qualification.
The another kind of embodiment of electromagnetic compatibility structure of the present invention can use to have and conduct electricity the bearing of grease and realize as the equipotential parts, like fore bearing, rear bearing, additional bearing etc. except that front and back bearings.
See also the structure cutaway view of another embodiment of Fig. 2 electromagnetic compatibility structure of the present invention.
As shown in Figure 2; The equipotential parts comprise a spindle guide fitting 18; This spindle guide fitting can be that sphere, hemisphere etc. be suitable for and axle produces the shape of sliding or rolling and contact, passes through elastic component 19 again like spring etc., links to each other with housing connector 20; And this housing connector can through press-fit, inlay, modes such as welding, stickup are fixed on the inner walls, realize rotating parts and fixed part housing or the equipotential purpose of negative pole.Said spindle guide fitting 18 can be arranged on the positions such as axle head, the shaft shoulder or annular groove of said relatively armature spindle 2.
To sum up; The present invention is through being provided with equipotential parts and armature spindle 2 direct-connected modes; Realized that armature spindle 2 is electrically connected with the effective of housing 10; Finally realize rotating part and retaining element housing or negative pole equipotential, thereby overcome not equipotential of existing generator complete machine excitation system and output system two loop low sides, the defective that electromagnetic interference is strong.
Seeing also Fig. 3 is the alternator construction cutaway view with electromagnetic compatibility structure provided by the invention.
The present invention disclose a kind of have an electromagnetic compatibility structure the brush alternating current generator arranged; With the equipotential parts is that the 3rd slip ring is set is the example explanation with the third brush that matches; As shown in Figure 3, said automobile-usedly have the brush alternating current generator to comprise: housing 10, be arranged at field frame assembly 16 in the housing 10, armature spindle 2, rotor assembly 17, rectifier stack 13, voltage regulator 11, slip ring assembly 12, brush assembly of electric 3, rear bearing 14, fore bearing 15 etc.The 3rd slip ring 1 is press-fited on rotor shaft for alternator 2, and third brush 4 is set on brush assembly of electric 3 opposite positions is used, with third brush lead-in wire 5 and generator negative pole (housing) welding with the 3rd slip ring 1.
When the given excitation signal of car load, after voltage regulator 11 received signal, brush assembly of electric 3 was communicated with slip ring assembly 12; Begin the to switch on excitation rotation of generator amature 17 coils produces magnetic field and makes stator 16 coil cutting magnetic induction lines, and then produces three-phase electromotive force; After rectifier stack 13 carries out the all-wave three phase rectifier; Form steady voltage, and after voltage regulator 11 is adjusted to Full Vehicle System voltage, export once more, provide vehicle mounted electrical equipment operate as normal required energy.Whole generating machine rotor part only is supported on the forward and backward housing 10 through fore bearing 15 and rear bearing 14; Can find out among the figure, remove the 3rd slip ring 1 after, complete machine structure is existing generator designs structure; Complete machine excitation system and output system two loop low sides are equipotential not, and electromagnetic interference is strong; And increased this and armature spindle 2 direct-connected the 3rd slip rings 1, and realized that then armature spindle 2 is electrically connected with the effective of housing 10, finally realized this EMC Design theory of rotating part and retaining element housing or negative pole equipotential, and be able to implement.
Certainly; The present invention also can have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
