The present invention relates to a dual structured electromechanical braking actuator for a railway vehicle with a fail-safe function, comprising: a power unit generating a rotational force by driving first and second electric motors in accordance with control of a motor controller; a rotating screw drum unit including first and second rotating screw drums provided on the left and right sides, which receive the rotational force of the first and second electric motors; a first linear screw drum unit converting rotational motion of the first rotating screw drum to leftward linear motion; and a second linear screw drum unit converting the rotational motion of the second rotating screw drum to rightward linear motion. The dual structured electromechanical braking actuator for the railway vehicle with the fail-safe function according to the present invention is capable of shortening an idle running time by driving a braking device with an electric signal and enables construction of a braking system having quick response characteristics and high reliability, which generates a constant reproducible braking force even during changes in the external temperature.

    본 발명은 이중구조의 Fail-Safe 기능을 갖는 철도차량용 전기기계식 제동엑츄에이터에 관한 것으로; 모터제어기의 제어에 의해 제1 및 제2 전기모터를 구동시켜 회전력을 발생하는 동력부와, 상기 제1 및 제2 전기모터의 회전력을 전달받는 제1 및 제2회전나사드럼이 좌측과 우측에 구비되는 회전나사드럼부와, 상기 제1회전나사드럼의 회전운동을 좌측방향으로 직진 운동하도록 변환하는 제1 직선나사드럼부와, 상기 제2회전나사드럼의 회전운동을 우측방향으로 직진 운동하도록 변환하는 제2 직선나사드럼부로 구성되는 것을 특징으로 한다. 본 발명에 따른 이중구조의 Fail-Safe 기능을 갖는 철도차량용 전기기계식 제동엑츄에이터는 전기적인 신호로 제동장치를 구동함에 따라 공주시간을 획기적으로 단축시킬 수 있으며, 외부 온도변화에 관계없이 재현성 있는 제동력을 일정하게 발생시킬 수 있는 빠른 응답특성 및 높은 신뢰도를 갖는 제동시스템 구축의 효과가 있다.
