Abstract
The utility model discloses a novel car motor, including dust cover, carbon brush frame, rear end cap, front end housing and rotor assembly, set up the rotor assembly between rear end cap and the front end housing, the rotor assembly is by collecting ring, main shaft, bluff piece, coil and bearing, and wherein the afterbody surface cover of main shaft has the collecting ring, and the collecting ring contact sets up on the carbon brush of carbon brush frame, the bottom of carbon brush frame fixed connection rear end cap, the contact of carbon brush frame and the outside of collecting ring set firmly the brush yoke dust cover. This practicality has increased effective power through the collecting ring with the carbon brush magnetic conduction after not increasing complete machine overall dimension with under the prerequisite of weight, change the carbon brush structure into to the cost is reduced has improved productivity ratio.
Description
Technical field
The utility model relates to a kind of electric motor of automobile, specifically a kind of novel electric motor of automobile.
Background technology
Electric motor of automobile is widely used in automobile making, and existing electric motor of automobile all adopts brushless electric machine, because the volume of brushless electric machine is little, and working stability, but the air magnetic conduction power of brushless electric machine is low, makes motor working efficiency not high, thus reduces the performance of vehicle.
Utility model content
The purpose of this utility model is to provide a kind of novel electric motor of automobile, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of novel electric motor of automobile, comprise dust cover, carbon brush holder, rear end cap, front end housing and rotor assembly, between described rear end cap and front end housing, rotor assembly is set, rotor assembly is by collector ring, main shaft, bluff piece, coil and bearing, wherein the tail surface cover of main shaft has collector ring, collector ring contact is arranged on the carbon brush of carbon brush holder, and carbon brush holder is fixedly connected with the bottom of rear end cap, and the contact of described carbon brush holder and the outside of collector ring set firmly brush holder dust cover.
As further program of the utility model: be installed with upper and lower two bluff pieces in the middle part of described main shaft.
As further program of the utility model: the afterbody of described rear end cap arranges rectifier assembly.
As further program of the utility model: the afterbody of rear end cap is sealed by dust cover.
As further program of the utility model: the head of described main shaft connects belt pulley.
Compared with prior art, the beneficial effects of the utility model are: this practicality, not increasing machine shape size with under the prerequisite of weight, after changing carbon brush structure into, adds effective power by collector ring with carbon brush magnetic conduction, and reduce cost, improve productivity ratio.
Accompanying drawing explanation
Fig. 1 is the partial exploded view of the utility model rear end cap afterbody.
Fig. 2 is the structural representation of rotor assembly.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, a kind of novel electric motor of automobile, comprise dust cover screw 1, dust cover 2, wiring board fixed screw 3, rectifier assembly 4, brush holder dust cover 5, carbon brush holder fixed screw 6, carbon brush holder 7, rear end cap 8, collector ring 9, main shaft 10, bluff piece 11, bearing 12, front end housing 13, belt pulley 14 and rotor assembly 15, between described rear end cap 8 and front end housing 13, rotor assembly 15 is set, rotor assembly 15 is by collector ring 9, main shaft 10, bluff piece 11, coil 16 and bearing 12, wherein the tail surface cover of main shaft 10 has collector ring 9, collector ring 9 contact is arranged on the carbon brush of carbon brush holder 7, carbon brush holder 7 is fixedly connected with the bottom of rear end cap 8, the contact of described carbon brush holder 7 and the outside of collector ring 9 set firmly brush holder dust cover 5, thus play the effect of fixing brush holder and dust-proof interference.
Arrange upper and lower two bluff pieces 11 in the middle part of described main shaft 10 with coil 16, technique is herein: two bluff pieces 11 are pressed on main shaft 10 with coil 16 simultaneously and produce.
The afterbody of described rear end cap 8 arranges rectifier assembly 4, and the afterbody of rear end cap 8 is sealed by dust cover 2.
The head of described main shaft 10 connects belt pulley 14.
Former brushless electric machine air magnetic conduction power is low, not increasing machine shape size with under the prerequisite of weight, after changing carbon brush structure into, adding effective power, and reducing cost, improve productivity ratio by collector ring with carbon brush road magnetic.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
