The present invention relates to an electronic parking brake actuator assembly. The electronic parking brake actuator assembly includes: a main housing (30) integrated with a motor installation part (31) and a gear installation part (40); a motor part (20) assembled with the motor installation part (31) of the main housing (30); a gear part (70) assembled with the gear installation part (40) of the main housing (30) and interlocked to be rotated by the rotation force of the motor part (20); and a cover assembled with the main housing (30) to close the motor part (20) and the gear part (70). A brush card assembly (50) is directly assembled with the motor installation part (31), and terminals (56) constituting the brush card assembly (50) are inserted and injected into the motor installation part (31). According to the present invention, the motor part (20) and the gear part (70) are not pre-assembled but are assembled directly with the main housing (30) as a structure for the assembly of the motor part (20) and the gear part (70) is made in the main housing (30). Thus, the number of components and assembly processes for an actuator can be reduced, and, as a result, costs for manufacturing the actuator can be lowered.

    본 발명은 전자식 주차 브레이크 액츄에이터 조립체에 관한 것이다. 본 발명은 모터설치부(31) 및 기어설치부(40)가 일체로 만들어지는 메인하우징(30)과, 상기 메인하우징(30)의 모터설치부(31)에 조립되는 모터부(20)와, 상기 메인하우징(30)의 기어설치부(40)에 조립되고 상기 모터부(20)의 회전력에 의해 맞물려 회전되는 기어부(70)와, 상기 메인하우징(30)에 조립되어 모터부(20) 및 기어부(70)를 차폐하는 커버를 포함하고, 상기 모터설치부(31)에는 브러시카드조립체(50)가 직접 조립되되 상기 브러시카드조립체(50)를 구성하는 터미널(56)은 상기 모터설치부(31)에 인서트사출된다. 본 발명에서는 모터부(20)와 기어부(70)가 미리 조립되지 않고, 메인하우징(30)에 바로 조립된다. 이것은 메인하우징(30)에 모터부(20)와 기어부(70)의 조립을 위한 구조가 만들어져 있기 때문에 가능한 것으로, 이를 통해 액츄에이터의 부품수와 조립공수가 줄어들고, 결과적으로는 액츄에이터의 제조비용이 낮아지게 된다.
