Support, collector ring of the rotor windings through being socketed on armature spindle and carbon brush electrical connection, formed by belt drive rotation during work
Rotating excitation field；Stator includes stator core and stator winding, and stator, which is located at, to be surrounded and formed in installation cavity simultaneously by drive end bearing bracket, rear end cap
It is arranged on by stator core on drive end bearing bracket, passes through stator cutting magnetic line during work and produce electric current；Rectifier is used for will exchange
Direct current is converted into, adjuster is used to control the electrical equipment such as output voltage, rectifier, adjuster, carbon brush to be typically mounted on rotor
In cavity between rear end cap.
In said structure, carbon brush is arranged on a carbon brush holder, has the brush box placed for carbon brush on carbon brush holder, in installation carbon
Brush it is latter as by spring and make its under stress with sliding surface keep contact, in some cases, the length of brush box inner chamber is spent
Long, carbon brush, with build-up of pressure deficiency after sliding surface contact wear, makes carbon brush cisco unity malfunction under Spring driving, and to increase
The electricity of conversion is added to need to increase the quantity of carbon brush, and traditional method is exactly the circumferential arrangement increasing on the end face of carbon brush holder
Add the quantity of brush-box, due to needing to keep certain interval make it that space is extremely narrow between brush-box.
The content of the invention
To solve the above problems, the purpose of this utility model is to provide a kind of long lifespan and electricity transformation efficiency is high
Automobile current generator, mainly increase the installation number reality of carbon brush by increasing assistant spring seat to spring and improving carbon brush holder structure
It is existing.
To achieve the above object, the utility model provides following technical scheme：A kind of long lifespan and electricity conversion effect
The high automobile current generator of rate, including housing, stator module, rotor assembly, carbon brush holder, carbon brush and belt pulley, described rotor
There is armature spindle on component, described carbon brush holder, described carbon brush holder front and back difference are arranged with described armature spindle
Annular array has several carbon brush grooves, and the carbon brush groove at the positive back side on the carbon brush holder interlocks circumferential arrangement at regular intervals, carbon
The described carbon brush of installation, is provided with spring in the afterbody of the carbon brush, is installed between the bottom land of spring and carbon brush groove in brush groove
There is the assistant spring seat of quality of rubber materials.
The spring groove being caught in for the spring one end is provided with one end of the assistant spring seat, in the assistant spring seat
The other end relative with described spring groove is convexly equipped with elastic cambered surface.
The base diameter of the elastic cambered surface is less than the diameter of bore of the spring.
Had the beneficial effect that by using what above-mentioned technical proposal was reached：Between front carbon brush groove and back side carbon brush groove are pressed necessarily
After staggeredly circumferential arrangement, more carbon brush quantity can be installed in same space and make it that electric energy conversion efficiency is higher, and
It is provided between the bottom land of spring and carbon brush groove after the assistant spring seat of quality of rubber materials, it is possible to provide the more extruding forces of spring,
Make carbon brush groove（Brush box）When the length of inner chamber is long, after carbon brush abrasion under the process auxiliary drive of assistant spring seat all the time with rotating shaft
Sliding surface contacts, and has so just reached long lifespan and the high technique effect of electricity transformation efficiency.
The utility model is further described with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment；
Fig. 2 is the enlarged drawing of A in Fig. 1；
Fig. 3 is the lower view of carbon brush holder in the utility model embodiment；
Fig. 4 is the top view of carbon brush holder in the utility model embodiment.
Embodiment
As shown in Fig. 1-Fig. 4, this long lifespan and the high automobile current generator of electricity transformation efficiency, including it is housing 1, fixed
Sub-component 2, rotor assembly 3, carbon brush holder 4, carbon brush 5 and belt pulley 8, have armature spindle 31 on rotor assembly 3, on armature spindle 31
Carbon brush holder 4 is arranged with, 4 positive annular array of carbon brush holder there are several front carbon brush grooves 41, has in the back side annular array of carbon brush holder 4
Several back side carbon brush grooves 42, front carbon brush groove 41 and back side carbon brush groove 42 it is close to each other and at regular intervals interlock circumferential row
Row, carbon brush groove（41、42）Interior installation carbon brush 5, is provided with spring 6, in spring 6 and carbon brush groove in the afterbody of carbon brush 5（41、42）'s
The assistant spring seat 7 of quality of rubber materials is installed between bottom land.
The spring groove 71 that the one end of ammunition feed spring 6 is caught in is provided with one end of assistant spring seat 7, in assistant spring seat 7 and spring
The relative other end of groove 71 is convexly equipped with elastic cambered surface 72.Effect can be such that spring 6 positions well, and be played by elastic cambered surface 72
The effect supply auxiliary force of carbon brush 5 of elasticity.
The base diameter of elastic cambered surface 72 is less than the diameter of bore of spring 6.Elastic cambered surface 72 can so be made to play a role
When can somewhat squeeze into the endoporus of spring 6, spring 6 uphold after elastic cambered surface 72 slowly from the endoporus of spring 6 elasticity extruding
Out, increase the auxiliary force of the elasticity of spring 6, effectively improve the service life of carbon brush 5 so as to extend the service life of engine.
In embodiment, front carbon brush groove 41 and back side carbon brush groove 42 interlock after circumferential arrangement at regular intervals, same
More quantity of carbon brush 5 can be installed in space and make it that electric energy conversion efficiency is higher, and in spring 6 and carbon brush groove（41、42）Groove
It is provided between bottom after the assistant spring seat 7 of quality of rubber materials, it is possible to provide 6 more extruding forces of spring, make carbon brush groove（41、42）
（Brush box）When the length of inner chamber is long, carbon brush 5 wear after under the process auxiliary drive of assistant spring seat 7 sliding surface with rotating shaft all the time
Contact, long lifespan and the high technique effect of electricity transformation efficiency are so just reached.
