The present invention relates to an electric motor type braking actuator using a rotating screw drum method. The electric motor type braking actuator includes: a motor unit which generates a rotating force in accordance with a braking command of a vehicle braking engine control unit (ECU); a reduction gear unit which increases the torque in accordance with the speed reduction motor of RPMs of the motor unit; a rotating screw drum which is integrated and connected to the reduction gear and has a male screw line formed on the outer periphery to rotate; and a straight screw drum which has a female screw line formed on the inner periphery to mesh with the male screw line of the rotating screw drum to convert the rotational movement of the rotating screw drum to a linear movement. According to the present invention, the electric motor type braking actuator drives a braking device of a train vehicle or ordinary vehicle with an electrical signal to significantly reduce the braking time due to quick response characteristics during a vehicle braking operation and is highly reliable by constantly generating the braking force of reproducible performance regardless of external temperature changes.

    본 발명은 회전나사드럼방식의 전기모터식 제동엑츄에이터에 관한 것으로; 차량 제동 ECU의 제동지령에 따라 회전력을 발생하는 구동모터부, 상기 구동모터부의 회전수의 감속비에 맞추어 토크를 증가시키는 감속기어부, 상기 감속기어부의 출력축과 일체로 연결되고 외주연에 수나사선이 형성되어 회전운동을 하는 회전나사드럼과, 상기 회전나사드럼의 수나사선이 치합되는 암나사선이 내주연에 형성되어 상기 회전나사드럼의 회전운동을 직진 운동으로 변환하는 직진나사드럼으로 구성되는 것을 특징으로 한다. 본 발명에 따르면, 철도차량 및 일반차량 등의 제동장치를 전기적인 신호로 구동함에 따라 차량 제동시 빠른 응답특성으로 인해 공주시간을 대폭 단축시킬 수 있고, 외부 온도변화에 관계없이 재현성 있는 제동력을 일정하게 발생시킬 수 있 신뢰도 역시 높은 장점이 있다.
