The present invention relates to an electronic parking brake actuator assembly. The assembly includes: an outer housing (10) having an internal space (10′) where a gear installation space (13) and a motor installation space (12) are separately formed; an inner housing (30) installed in the internal space (10′) of the outer housing (10), and having a brush card part (31) and a gear installation part (34) formed to be integrated; a motor assembly (1) combined with the brush card part (31) to be electrically connected, and installed in the motor installation space (12); gear assemblies installed in the gear installation part (34) and the gear installation space (13) respectively to deliver the rotation speed of the motor assembly (1) by changing the same; and a cover housing (20) combined with the outer housing (10) while having the inner housing (30) laid therebetween, and having a shaft insertion part formed such that one side is dented. According to the present invention, the electronic parking brake actuator assembly is capable of eliminating an inner cover covering an upper part of an existing gear assembly, and forming an idle shaft insertion part and a deceleration gear shaft insertion part in a cover housing to reduce the number of components, thus reducing accumulated tolerances. Also, the present invention can have an effect of reducing the total number of assembly processes.

    본 발명은 전자식 주차 브레이크 액추에이터 조립체에 관한 것으로, 내부공간(10')에 기어설치공간(13)과 모터설치공간(12)이 각각 형성된 외부하우징(10)과, 상기 외부하우징(10)의 내부공간(10')에 설치되고, 브러시카드부(31)와 기어설치부(34)가 일체로 형성된 내부하우징(30)과, 상기 브러시카드부(31)와 결합되어 전기적으로 연결되고, 상기 모터설치공간(12)에 설치되는 모터조립체(1)와, 상기 기어설치부(34) 및 기어설치공간(13)에 각각 설치되어 상기 모터조립체(1)의 회전속도가 변화하여 전달하는 기어조립체와, 상기 내부하우징(30)을 사이에 두고 상기 외부하우징(10)과 결합되며, 일면이 요입되게 축삽입부가 형성되는 커버하우징(20)을 포함한다. 본 발명에 의하면, 종래에 기어조립체의 상부를 덮는 내부 커버를 삭제하고, 커버하우징 자체에 아이들축삽입부와 감속기어축삽입부가 형성되므로 부품수가 감소하고, 이에 따른 누적공차를 줄일 수 있다. 또한, 전체조립공수가 감소하는 효과가 있다.
