Abstract

본 발명은 브레이크 작동 감응식 엔진 동력 차단장치에 관한 것으로서, 브레이크 페달 근접부위에는 브레이크 작동을 감지할 수 있도록 전자제어장치에 연결된 감지센서가 부착되고, 전자제어장치에 브레이크 패달의 답입량에 따라 엔진의 분당 회전수를 감지하는 회전수 감지센서가 연결되며, 전자제어장치에는 브레이크 페달 작동시 엔진 회전수가 설정치 이하(1000 RPM)일때 클러치의 작동을 제어시킬 수 있도록 에어탱크의 공압이 제공된 마그네트 밸브가 연결되고, 마그네트 밸브에는 공압에 따라 이동되어 트랜스미션의 입력축으로 전달된 엔진의 회전력을 차단시키기 위해 피스톤이 내설된 클러치 작동 실린더가 장착되고, 피스톤 일단부에는 힌지를 중심으로 회전하여 클러치를 수동적으로 작동시키는 링크가 고정됨으로써, 브레이크 미숙 및 엔진의 과부하에 따른 엔진의 정지를 미연에 방지할 수 있음은 물론 브레이크 조작 후 차량을 정상적으로 운행시킬 수 있다.The present invention relates to a brake actuation-sensitive engine power cut-off device, wherein a proximity sensor is attached to a brake pedal to detect an operation of a brake, and a detection sensor connected to the electronic control device is attached to the electronic control device according to the depression amount of the brake pedal. A rotation speed sensor is used to detect the revolutions per minute, and the electronic control unit has a magnet valve provided with air pressure in the air tank to control the clutch operation when the engine speed is lower than the set value (1000 RPM) when the brake pedal is operated. The magnetic valve is equipped with a clutch actuating cylinder with a built-in piston to block the rotational force of the engine, which is moved according to pneumatic pressure and transmitted to the input shaft of the transmission, and one end of the piston rotates about the hinge to manually operate the clutch. Brakes are fixed so that the brake is immature It is possible to prevent the engine from being stopped due to overload of the jeans, and to operate the vehicle normally after the brake operation.
