Abstract
본 발명은 브레이크 액 리저버내의 수위와 압력을 감지하여 그 감지결과를 기초로 브레이크의 이상상태를 판단하여 브레이크의 이상상태를 경보할 수 있도록 된 드럼식 브레이크 이상경보장치를 제공한다.The present invention provides a drum type brake abnormality warning device capable of detecting a level and a pressure in a brake fluid reservoir and determining an abnormal state of the brake based on a result of the detection, thereby alerting an abnormal state of the brake.
그에 따라 본 발명은 바퀴와 일체형으로 회전하는 브레이크 드럼(5)내에 2개의 브레이크슈(6)가 설치되고, 그 브레이크 슈(6)의 외면에 압착된 브레이크 라이닝(8)이 상기 브레이크 드럼(5)에 접촉하여 발생되는 마찰력에 의해 제동하는 드럼식 브레이크에 있어서; 브레이크 액 리저버(7)의 내면 상단과 중단에 각각 설치되어 브레이크 액의 수위에 따라 온/오프되는 제1,2리미트스위치(10,12)와 상기 브레이크 액 리저버(7)의 내면하단에 설치되어 상기 브레이크 액의 압력에 따라 온/오프되는 압력스위치(14), 상기 제1,2리미트스위치(10,12)와 상기 압력스위치(14)로부터의 검출신호를 근거로 브레이크의 이상상태를 판단하여 브레이크 이상상태가 경고되도록 제어하는 제어부(16); 상기 제어부(16)의 제어하에 브레이크 이상시 브레이크경고등(20)이 점등되도록 하는 램프구동부(18) 및 브레이크 이상시 부저음을 발생하는 부저(22)를 포함하여 구성되는 것을 특징으로 한다.Accordingly, the present invention is characterized in that two brake shoe (6) are provided in a brake drum (5) rotating integrally with a wheel, and a brake lining (8) pressed on the outer surface of the brake shoe (6) And a braking device for braking the brakes by friction force generated by contact with the brakes. First and second limit switches 10 and 12 provided respectively at an upper end and an inner end of the brake fluid reservoir 7 to be turned on and off in accordance with the level of the brake fluid and a brake fluid reservoir 7 provided at the lower end of the brake fluid reservoir 7 An abnormality of the brake is determined on the basis of a pressure switch 14 which is turned on / off in accordance with the pressure of the brake fluid, a detection signal from the first and second limit switches 10 and 12 and the pressure switch 14 A controller (16) for controlling the brake abnormal state to be warned; A lamp driving unit 18 for turning on the brake warning lamp 20 when a brake abnormality occurs under the control of the controller 16 and a buzzer 22 for generating a buzzer sound when the brake abnormality occurs.
