Description
Technical field
The utility model belongs to automotive engineering field, and in particular to a kind of AC generator for vehicle for reducing electromagnetic noise.
Background technique
In automotive engineering field, especially electric car, AC generator for vehicle work when can generate mechanical noise and
Electromagnetic noise, mechanical noise be mechanical equipment operating when component between frictional force, impact force or unbalanced force make mechanical part and
The sounding bodies such as shell generate the irregular noise for vibrating and giving off, and electromagnetic noise is alternately to be changed by electromagnetic field and caused certain
Mechanical part or spatial volume vibration and the noise generated, common electromagnetic noise producing cause have coil and iron core gap it is big,
Improper, coil magnetic saturation etc. that coil loosens, carrier frequency is arranged.
Mechanical noise and electromagnetic noise can all influence the service life and whole comfortable of automobile of AC generator for vehicle
Degree, in order to reduce noise, people absorb vibration by installation rubber ring to reduce noise, but current rubber ring is all
It is mounted at hole axle cooperation or between engine support and engine, mechanical noise can only be reduced, electromagnetic noise can not be reduced.
As depicted in figs. 1 and 2, currently, AC generator for vehicle includes field frame assembly, rotor assembly, drive end bearing bracket and rear end
Lid, rotor assembly shaft is respectively supported on drive end bearing bracket and rear end cap by bearing, field frame assembly respectively with drive end bearing bracket and rear end
Lid rigid connection fix, field frame assembly, drive end bearing bracket and rear end cap by rotor assembly surround and field frame assembly face rotor assembly magnetic
Property part, drive end bearing bracket and rear end cap with engine support for being connected and fixed.
Utility model content
The purpose of the utility model is to provide a kind of AC generator for vehicle for reducing electromagnetic noise, the automobile alternative electric generations
Machine reduces electromagnetic noise, good damping result.
Technical solution used by the utility model is：
A kind of AC generator for vehicle reducing electromagnetic noise, including field frame assembly, rotor assembly, drive end bearing bracket and rear end
Lid, rotor assembly shaft are respectively supported on drive end bearing bracket and rear end cap by bearing, and field frame assembly, drive end bearing bracket and rear end cap will turn
Sub- assembly surrounds and field frame assembly face rotor assembly magnetic part, and drive end bearing bracket and rear end cap are connected with each other and by field frame assembly pressures
It fastens, is the rubber ring of L-type, the inside of rubber ring and stator across section between field frame assembly and drive end bearing bracket and rear end cap
Where the end face of assembly edge angle and side fitting, outside are stuck in the card slot of end cap.
Further, entire rubber ring is combined by several isometric segmentations.
It is improved as another kind, entire rubber ring is integrally formed.
Further, drive end bearing bracket and rear end cap are bolted.
The utility model has the beneficial effects that：
When work, electromagnetic force in air gap, generates rotation Reeb or pulsation Reeb between field frame assembly, rotor assembly,
So that field frame assembly is generated vibration and electromagnetic radiation noise, field frame assembly and drive end bearing bracket and rear end cap by after rubber ring assembly by rigid
Property connection become being flexibly connected, reduce the vibration amplitude of field frame assembly, reduce electromagnetic noise, moreover, rubber ring is by stator
Assembly edge angle package carries out vibration damping, good damping result in axially and radially both direction.

As shown in Figures 3 to 5, in example 1 and example 2, the AC generator for vehicle of electromagnetic noise is reduced, is wrapped
Field frame assembly 2, rotor assembly 1, drive end bearing bracket 3 and rear end cap 4 are included, 1 shaft of rotor assembly is respectively supported at drive end bearing bracket 3 by bearing
On rear end cap 4, field frame assembly 2, drive end bearing bracket 3 and rear end cap 4 surround rotor assembly 1 and 2 face rotor assembly 1 of field frame assembly
Magnetic part, drive end bearing bracket 3 and rear end cap 4 are connected with each other and are fixed field frame assembly 2, field frame assembly 2 and drive end bearing bracket 3 and after
It is the rubber ring 6 of L-type, the inside of rubber ring 6 and the end face and side of 2 edge angle of field frame assembly across section between end cap 4
Where fitting, outside are stuck in the card slot of end cap.When work, electromagnetic force in 1 field frame assembly 2, rotor assembly air gap,
Generate rotation Reeb or pulsation Reeb, field frame assembly 2 made to generate vibration and electromagnetic radiation noise, field frame assembly 2 and drive end bearing bracket 3 and
Rear end cap 4 is become being flexibly connected after assembling by rubber ring 6 from rigid connection, reduces the vibration amplitude of field frame assembly 2, is reduced
Electromagnetic noise carries out vibration damping in axially and radially both direction, subtracts moreover, rubber ring 6 wraps up field frame assembly 2 edge angle
Effect of shaking is good.
As shown in figure 4, in example 1, entire rubber ring 6 is integrally formed.
As shown in figure 5, in example 2, entire rubber ring 6 is combined by several isometric segmentations.Rubber ring 6 is segmented
It is combined into, is easily installed, if concentrated wear is serious, need to only replace segmentation, it is not necessary to whole replacement.
As shown in Figure 4 and Figure 5, in example 1 and example 2, drive end bearing bracket 3 and rear end cap 4 are connected by bolt 5.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations all should belong to the protection scope of the appended claims for the utility model.
