본 발명은 직류 모터의 브러쉬 조립체에 관한 것이다.The present invention relates to a brush assembly of a direct current motor.

자동차에 설치된 ABS(Anti-Lock Brake System) 모터 및 시동 모터 등과 같은 자동차용 모터로는 직류 모터가 사용된다.DC motors are used for automobile motors such as anti-lock brake system (ABS) motors and starting motors installed in automobiles.

도 1은 종래의 직류 모터의 브러쉬 조립체를 보인 사시도로서, 이를 설명한다.1 is a perspective view illustrating a brush assembly of a conventional DC motor, which will be described.

도시된 바와 같이, 상호 결합된 하우징(미도시)과 커버(미도시)의 내부에 회전축(미도시)이 회전가능하게 설치되고, 상기 회전축의 외주면에는 정류자 결합된다. 상기 커버의 저면에는 상기 정류자와 접촉하는 브러쉬(13)를 가지는 브러쉬 조립체(10)가 결합된다.As shown, a rotating shaft (not shown) is rotatably installed inside the housing (not shown) and the cover (not shown) that are coupled to each other, and a commutator is coupled to an outer circumferential surface of the rotating shaft. A brush assembly 10 having a brush 13 in contact with the commutator is coupled to the bottom of the cover.

브러쉬 조립체(10)는 상기 커버의 저면에 결합된 브러쉬홀더(11), 일측은 브러쉬홀더(11)의 내부에 위치되고 타측은 브러쉬홀더(11)의 외측으로 노출되어 상기 정류자와 접촉하는 브러쉬(13), 브러쉬홀더(11)의 내부에 설치되어 브러쉬(13)를 브러쉬홀더(11)의 외측으로 탄성 지지하는 탄성부재(15)를 가진다.The brush assembly 10 is a brush holder 11 coupled to the bottom of the cover, one side is located inside the brush holder 11 and the other side is exposed to the outside of the brush holder 11 to contact the commutator ( 13) has an elastic member 15 installed inside the brush holder 11 to elastically support the brush 13 to the outside of the brush holder 11.

상기와 같은 종래의 브러쉬 조립체(10)는 조립공정 손실이 큰 단점이 있다. 상세히 설명하면, 브러쉬조립체(10)를 조립하여 상기 커버에 결합한 후, 브러쉬(13)가 브러쉬홀더(11)로부터 이탈되지 않도록 지그 등을 이용하여 브러쉬(13)를 눌러서, 상기 커버를 상기 하우징에 결합하면서 브러쉬(13)가 상기 정류자에 접촉되게 한다.The conventional brush assembly 10 as described above has a disadvantage in that the loss of the assembly process is large. In detail, after assembling and assembling the brush assembly 10 to the cover, by pressing the brush 13 using a jig or the like so that the brush 13 is not separated from the brush holder 11, the cover is pressed into the housing. While engaging, the brush 13 is brought into contact with the commutator.

그런데, 브러쉬홀더(11)에 탄성부재(15)와 브러쉬(13)가 단계별로 조립되므로, 조립공정 손실이 발생하는 단점이 있다.However, since the elastic member 15 and the brush 13 are assembled in the brush holder 11 step by step, there is a disadvantage in that an assembly process loss occurs.

또한, 브러쉬홀더(11) 및 브러쉬(15)에 탄성부재(15)를 지지하기 위한 아무런 수단이 없으므로, 브러쉬홀더(11)에 탄성부재(15)를 조립할 때나, 브러쉬 조립 체(10)를 상기 커버에 결합한 후 상기 커버를 상기 하우징에 결합할 때, 탄성부재(15)가 분실될 우려가 있다. 이로인해, 더욱 조립공정 손실이 발생하는 단점이 있다.In addition, since there is no means for supporting the elastic member 15 in the brush holder 11 and the brush 15, when assembling the elastic member 15 to the brush holder 11, the brush assembly 10 is described above. When the cover is coupled to the housing after the cover is coupled, the elastic member 15 may be lost. As a result, there is a disadvantage that the loss of the assembly process more.

While the brush 183 is in contact with the commutator 170.

본 실시예에 따른 직류 모터는 브러쉬(183)와 탄성부재(185)가 일체로 형성된다. 그러므로, 브러쉬(183)를 잡고서 탄성부재(185)측을 브러쉬홀더(181)의 내부에 삽입하면, 탄성부재(185) 및 브러쉬(183)가 조립되므로, 조립공정이 간단하다. 그리고, 탄성부재(185)가 브러쉬(183)에 일체로 형성되므로, 탄성부재(185)가 분실될 우려가 줄어든다. 탄성부재(185)는 사출에 의하여 브러쉬(183)와 일체로 형성된다.In the DC motor according to the present embodiment, the brush 183 and the elastic member 185 are integrally formed. Therefore, when the elastic member 185 is inserted into the brush holder 181 by holding the brush 183, the elastic member 185 and the brush 183 are assembled, so that the assembly process is simple. In addition, since the elastic member 185 is integrally formed with the brush 183, the risk of losing the elastic member 185 is reduced. The elastic member 185 is formed integrally with the brush 183 by injection.

도 4는 본 발명의 다른 실시예에 따른 브러쉬 조립체의 사시도로서, 탄성부재(285)가 브러쉬홀더(281)에 일체로 형성된다. 이 또한, 브러쉬홀더(281)에 브러쉬(283)만 조립하면 조립이 완료되므로, 조립공정이 간단하고 탄성부재(185)가 분 실될 우려가 줄어든다.Figure 4 is a perspective view of a brush assembly according to another embodiment of the present invention, the elastic member 285 is integrally formed in the brush holder 281. In addition, since assembling is completed by assembling only the brush 283 to the brush holder 281, the assembly process is simple and the risk of the elastic member 185 being lost is reduced.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 직류 모터의 브러쉬 조립체는 탄성부재가 브러쉬 또는 브러쉬홀더에 일체로 형성되므로, 한번의 작업으로 탄성부재 및 브러쉬가 브러쉬홀더에 조립된다. 그러므로, 조립 공정이 간편하여 조립 공정의 효율이 향상된다.As described in detail above, in the brush assembly of the DC motor according to the present invention, since the elastic member is integrally formed with the brush or the brush holder, the elastic member and the brush are assembled to the brush holder in one operation. Therefore, the assembly process is simple and the efficiency of the assembly process is improved.

또한, 탄성부재가 손실될 우려가 줄어들므로, 더욱 조립 공정의 효율이 향상된다.In addition, since the risk of losing the elastic member is reduced, the efficiency of the assembly process is further improved.
