The present invention relates to a door system for a cabin on a railroad car, which is durable and easy to maintain since there are no problems such as checking and replacing a belt due to failure and applying lubricant for smooth operation, and is excellent in responsiveness, operation accuracy, and reliability, and can minimize noise. According to the present invention, the door system comprises: a base member installed on a door frame; a door panel mounted on the base member to be slidably movable; a spindle rotatably installed on the base member; a motor coupled to one end of the spindle via a coupler and fixedly installed to the base member; and a nut for the spindle coupled to the spindle and moving in a longitudinal direction of the spindle when the spindle rotates and coupled to the door panel.

    본 발명은 고장 발생으로 인해 벨트 점검 및 교체, 원활한 작동을 위한 윤활제 도포 등과 같은 문제가 없어 내구성이 우수하고 유지보수가 용이하며, 응답성, 작동의 정확성 및 신뢰성이 우수하며 소음 발생을 최소화 할 수 있도록 하는 철도 차량 객실용 도어 시스템에 관한 것으로서, 도어 프레임에 설치되는 베이스 부재, 상기 베이스 부재에 장착되어 슬라이딩 이동 가능하게 설치되는 도어 패널, 상기 베이스 부재 상에 회전 가능하게 설치되는 스핀들, 상기 스핀들 일단에 커플러를 통해 결합되며 상기 베이스 부재에 고정 설치되는 모터 및 상기 스핀들에 결합되어 스핀들 회전시 스핀들 길이방향으로 이동하며 상기 도어 패널에 결합되는 스핀들용 너트를 포함하여 구성되는 것을 특징으로 한다.
