(9) Push the piston of the master cylinder to compress the hydraulic pressure to generate a mechanical brake without the power of the engine.
Description
본 고안은 자동차 부스터 기계식 겸용 제동 장치에 관한 것으로 더욱 상세하게는 부스터를 장착한 자동차가 고속 주행중 갑자기 시동정지로 부스터의 동력기능을 상실 했을 때 자동차 제동이 불완전한 것을 완전하게 제동 할수 있도록 한 구조의 자동차 부스터 기계식 겸용 제동장치에 관한 것이다. 종래의 자동차가 고속주행이나 비탈길 주행중 엔진시동이 정지로 인하여 제동능력이 불완전하여 사고 발생되는 일이 종종 있다. 종래의 부스터(동력 제동장치)를 장착한 자동차는 운행중 엔진 시동이 정지되면 제동장치가 동력을 상실하여 진공압에 의해 작동하는 부스터 내의 A 진공실에 대기압이 충진되므로 폐달을 밟을수록 딱딱해지면서 제동이 불완전해 운전자의 의지대로 움직여 주지 않으므로 사고를 유발케 되는 것이다.The present invention relates to an automobile booster mechanical brake system, and more specifically, a vehicle having a structure in which a vehicle equipped with a booster completely brakes an incomplete braking when the booster loses its power function due to sudden start stop during high-speed driving. It relates to a booster mechanical brake system. In a conventional vehicle, an accident occurs due to an incomplete braking ability due to an engine stop while driving at high speed or driving on a slope. In a vehicle equipped with a conventional booster (power braking device), when the engine is stopped while driving, the braking device loses power and the atmospheric pressure is filled in the vacuum chamber A in the booster operated by vacuum pressure. It is incomplete and does not move according to the driver's will, causing an accident.
본 고안은 이러한 자동차 부스터제동장치의 결점으로 인한 사고를 막기위해 창안된 것으로 자동차가 고속주행이나 비탈길 주행중 갑자기 엔진정지시 차를 정지 시키기 위하여 브레이크 페달을 밟아 쓸 때 부스터 A 진공실에 대기압(공기)이 충만되 다이어프램 피스톤이 움직이지 않으면 공기 밸브피스톤 하우징이 다이어프램 과 분리되면서 앞으로 전진 타이로드를 압축 매스터 실린더 유압 피스톤을 기계식으로 밀어 제동이 되도록 한 것이다.The present invention was devised to prevent accidents caused by faults of the automobile booster braking system. When the vehicle presses the brake pedal to stop the car suddenly when the engine stops during high speed driving or slope driving, the air pressure (air) is increased in the booster A vacuum chamber. If the diaphragm piston is full but the air valve piston housing is not diaphragm The forward tie rods are mechanically pushed against the compression master cylinder hydraulic piston to be braked.
