Description

드럼브레이크
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 교지에 따라 만들어진 에스컬레이터의 입면도.
제2도는 본 발명의 교지에 따라 만들어진 브레이크를 사용한 에스컬레이터의 구동 유니트의 평면도.
제3도는 본 발명의 교지에 따라 만들어진 브레이크가 제동이 가해진 상태에서 도해 되는 입면도.
제4도는 제동이 풀린 상태에서 브레이크 작동기구를 도해하는, 제3도에 도시된 브레이크의 부분도.
제5도는 제3도와 4도에 도시된 브레이크의, 기계적 작동기구와 작동 솔레노이드(solenoid)의 힘 특성을 도해하는 그래프.
제6도는 작동 솔레노이드의 여자(enerfization) 및 그의 방출이 완화되는 본 발명의 실시예를 도해하는, 제3도에 도시된 브레이크의 부분도.
제7도는 제3도에 도시된 브레이크의 실시예에서 사용되는 대쉬포트(dashpot)의 다른 설정을 도해하는 그래프.
제8도는 제3도에 도시된 브레이크 솔레노이드의 위치와 그리하여 제동력을 제어하기 위한 피이드백 배열의 일부 구성도 및 일부 블럭 다이아그램.
제9도는 슈유 피보트 포인트(shoe pivot point)의 위치와 드럼의 중심, 그리고 드럼의 직경 간의 관계를 도해하는, 제3도에 도시된 브레이크의 드럼과 브레이크 슈우중의 하나의 개략도.
제10도는 제9도에 도시된 관계를 이해하는데 도움이 되는 그래프.

Claims (2)

  1. 회전 브레이크 드럼과, 상기 브레이크 드럼에 대해 브레이크가 걸린 위치와 브레이크가 풀린 위치 사이에서 작동하며 브레이크 드럼의 한 회전 방향으로는 자 여자 되고 다른 방향으로는 부분적으로 부세 되어지게 놓여지는 브레이크 장치와, 상기 브레이크 장치를 브레이크가 걸린 위치로 첫번째 규정된 힘에 의하여 편향시키는 제1편향장치와 상기 첫번째 규정된 힘을 이겨서 상기 브레이크 장치를 브레이크가 풀린 위치로 작동시키는 전자 장치로 구성되어지며, 상기 전자 장치가 상기 브레이크 장치를 브레이크가 풀린 위로 동치시킬 때 설정된 축적된 힘으로 편향되어 지게 놓인 제2편향장치와, 상기 제2편향 장치내의 축적된 힘의 방출을 제어하기 위하여 브레이크 장치가 브레이크가 풀린 위치에서 브레이크가 걸린 위치로 작동될 때 유효한 제어장치와, 상기 제1 및 제2편향장치는 상기 브레이크 장치에 대해 상기 브레이크 장치에 의한 상기 브레이크 드럼에 가해진 제동력이 상기 제1 및 제2편향장치간의 어떤 순간에서의 차이에 응하게하여, 상기 브레이크 드럼에 가해진 제동력이 상기 제어장치가 제2편향 장치가 그 축적된 힘을 방출하게 하는 속도에 따라 낮은 값에서 시작하여 첫번째 규정된 힘까지 증가하게 배열되어지는 것을 특징으로 하는 스프링으로 걸려지며, 전기적으로 풀려지는 드럼브레이크.
