Abstract

본 발명은 지게차의 에어브레이크 시스템에서 전후진 레버를 조작시 록킹밸브를 통해 중립상태에서 브레이크가 작동하도록 하는 지게차의 전/후진 레버를 통한 에어브레이크 록킹시스템에 관한 것이다.The present invention relates to an air brake locking system through a forward / reverse lever of a forklift truck such that the brake is operated in a neutral state through a locking valve when operating the forward / backward lever of the forklift air brake system.

본 고안의 구체적인 수단은, 에어탱크로부터 압축된 공기를 개폐시키는 브레이크 밸브와 인칭밸브에 연결되어 입력된 높은 압력측의 공기를 개방하는 디바이드 밸브와, 이 디바이드밸브의 입력된 공기를 2개의 에어스프링 챔버로 보내고 동시에 순간 압력의 감소에 따라 리턴압력을 방출하는 릴리즈 밸브와, 상기 에어 스프링챔버의 로드와 연결되어 브레이크장치의 캠샤프트에 연결되어 회전운동으로 브레이크장치에 제동력을 전달하고 간극조정이 가능하도록 한 슬랙어저스트를 갖는 지게차의 브레이크 록킹 시스템에 있어서, 상기 브레이크 밸브의 출구측 라인과 에어탱크의 출구포트에 튜브어셈블리로 연결되어 전후진 레버의 전진에서 후진 또는 후진에서 전진동작에 따라 에어탱크의 압축공기를 상기 디바이드밸브로 보내도록 하여 브레이크가 작동되도록 하는 록킹밸브를 설치한 것을 특징으로 한다.Specific means of the present invention is a brake valve for opening and closing the compressed air from the air tank, a divide valve for opening the air of the high pressure side input to the inching valve, and the input air of the divide valve two air springs A release valve that sends to the chamber and releases the return pressure according to the decrease in the instantaneous pressure, and is connected to the rod of the air spring chamber and connected to the cam shaft of the brake device to transmit the braking force to the brake device by rotational movement and adjust the clearance. In the brake locking system of a forklift truck having a slack adjust, a tube assembly is connected to the outlet side line of the brake valve and the outlet port of the air tank so that the air tank can be operated according to the forward or backward movement of the forward and backward levers. Pressurized air to the divide valve Characterized in that a locking valve to operate.
