본 고안은 차량, 특히 지게차의 파킹 브레이크와 서비스 브레이크의 연동장치에 관한 것이다.The present invention relates to a linkage between a parking brake and a service brake of a vehicle, in particular a forklift.
종래에는 에어탱크에서 서비스 브레이크밸브와 파킹 브레이크밸브로 각각의 압축공기 공급라인이 설치되어 독립하여 작동하도록 되어 있었다.Conventionally, each compressed air supply line has been installed from the air tank to the service brake valve and the parking brake valve to operate independently.
그에 따라 구조가 매우 복잡하고 파킹 브레이크밸브가 개방된 상황에서 운전자의 부주의로 서비스 브레이크를 작동시키는 경우 압축공기가 브레이크 라이닝에 연결된 피스톤 로드작동용 에어스프링 챔버에 과도한 공기압이 작용하여 부품을 손상시켜 수명이 단축되는 문제가 있었다.As a result, when the service brake is inadvertently operated when the parking brake valve is very complicated and the parking brake valve is opened, excessive air pressure is applied to the piston rod actuating air spring chamber connected to the brake lining, causing damage to the parts. There was a problem of being shortened.
본 고안의 목적은 복잡하지 않은 구조를 상기 종래 기술의 문제점을 해소하여 파킹 브레이크의 작동시 서비스 브레이크를 작동시키더라도 에어 스프링챔버로의 공기압이 조정되어 에어 스프링챔버를 손상시키지 않는 파킹 브레이크와 서비스 브레이크 연동장치를 제공하는 것이다.An object of the present invention is to solve the problem of the prior art, the parking brake and the service brake does not damage the air spring chamber by adjusting the air pressure to the air spring chamber even if the service brake is operated during the operation of the parking brake to solve the problem of the prior art It is to provide an interlock device.
본 고안에 따른 파킹 및 서비스 브레이크 연동장치는 에어탱크와 그로부터 연장된 공급라인에 서비스 브레이크밸브와 파킹 브레이크밸브를 장착하고 서비스 브레이크밸브와 파킹 브레이크밸브 사이에 첵밸브가 제공되며,서비스 브레이크밸브로부터 에어스프링챔버로의 공압라인에 릴리즈밸브가 제공되고 파킹 브레이크밸브로부터 에어 스프링챔버로의 공압라인에 퀵 릴리즈밸브가 제공되며, 상기 릴리즈밸브와 퀵 릴리즈밸브 사이에는 공압밸런스라인이 제공되어 서비스 브레이크밸브와 파킹 브레이크밸브로부터 전달되어 에어 스프링챔버에 작용하는 공기압이 일정하도록 연동시키는 구성으로 되어있다.The parking and service brake interlock according to the present invention is provided with a service brake valve and a parking brake valve in an air tank and a supply line extending therefrom, and a check valve is provided between the service brake valve and the parking brake valve. A release valve is provided on the pneumatic line to the spring chamber, and a quick release valve is provided on the pneumatic line from the parking brake valve to the air spring chamber, and a pneumatic balance line is provided between the release valve and the quick release valve. It is configured to interlock so that the air pressure transmitted from the parking brake valve and acting on the air spring chamber is constant.
이하 첨부도면을 참고하여 본 고안을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.
제 1 도와 2도에서, 에어탱크(1)로부터의 공압라인(2)에 서비스 브레이크밸브(3)가 연결되어 있고 이어서 첵벨브(4)를 통하여 파킹 브레이크밸브(5)가 제공되어 있다. 상기 서비스 브레이크는 브레이크 패달로 작동되는 통상의 브레이크이고, 파킹 브레이크는 파킹시 손으로 조작하는 소위 사이드 브레이크이다. 서비스 브레이크밸브(3)의 출력측 공압라인(12)은 릴리즈밸브(6)를 통하여 에어 스프링챔버(7)로 연결되고, 파킹 브레이크밸브(5)의 출력측 공압라인(8)은 퀵 릴리즈밸브(9)를 통해 에어 스프링챔버(7)에 연결되어 있다. 에어 스프링챔버(7)의 피스톤로드는 조정기(9)를 회전 또는 역회전시켜 도면에 도시되지 않은 브레이크 라이닝을 확장 또는 수축시켜 브레이크작용을 한다.In FIGS. 1 and 2, a service brake valve 3 is connected to the pneumatic line 2 from the air tank 1, and then a parking brake valve 5 is provided through the check valve 4. The service brake is a conventional brake operated by a brake pedal, and the parking brake is a so-called side brake which is operated by hand when parking. The output pneumatic line 12 of the service brake valve 3 is connected to the air spring chamber 7 via the release valve 6, and the output pneumatic line 8 of the parking brake valve 5 is a quick release valve 9. Is connected to the air spring chamber (7). The piston rod of the air spring chamber 7 rotates or counter-rotates the regulator 9 to expand or contract the brake lining not shown in the drawing to brake.
상기 릴리즈밸브(6)와 퀵 릴리즈밸브(9)는 밸런스 라인(10)으로 연통되어 있어서 서비스 브레이크 밸브(3)와 파킹 브레이크 밸브(5)를 운전자의 실수로 동시에 개방하더라도 에어 스프링챔버(7)에 작용하는 공압은 밸브(3,5)가 각각 작용할 때와 동일하여 에어 스프링챔버(7)에 과도한 공압이 작용하지 않으므로 손상이 방지된다. 또한, 서비스 브레이크밸브(3)의 출력축 공압라인(12)에는 분할밸브(11)가 제공되어 도면에 도시되지 않은 인칭밸브와 연결된다. 서비스 브레이크 또는 파킹 브레이크를 풀면, 릴리즈밸브(6)와 퀵 릴리즈밸브(9)는 에어 스프링챔버(7)로의 공압 공급을 차단하는 한편 작용하던 공압은 순간적으로 소멸되어 도시되지 않은 브레이크의 스프링력에 의해 바퀴에서 라이닝이 떨어져 구동가능한 상태로 된다.The release valve 6 and the quick release valve 9 communicate with the balance line 10 so that the air spring chamber 7 may be opened even if the service brake valve 3 and the parking brake valve 5 are opened at the same time by a driver's mistake. The pneumatic pressure acting on the valve is the same as when the valves 3 and 5 act, respectively, so that excessive pneumatic pressure is not applied to the air spring chamber 7, thereby preventing damage. In addition, the output shaft pneumatic line 12 of the service brake valve 3 is provided with a split valve 11 is connected to the inching valve not shown in the figure. When the service brake or parking brake is released, the release valve 6 and the quick release valve 9 shut off the pneumatic supply to the air spring chamber 7, while the actuated pneumatics are momentarily dissipated to the spring force of the brake (not shown). This causes the lining to fall off the wheel and become driven.
본 고안에 따라, 에어 탱크(1)로부터의 공압라인(2)에 첵벨브(4)를 사용하여 서비스 브레이크밸브(3)와 파킹 브레이크밸브(5)를 연결하여 사용함으로써 종래에 2개의 공압라인으로 구성한 것에 비해 매우 단순화되어 있으며, 또한 릴리즈밸브(6)와 퀵 릴리즈밸브(9)를 각각 서비스 브레이크밸브(3)와 파킹 브레이크밸브(5)로부터의 출력측공압라인(8,12)에 설치하고 밸런스라인(10)으로 연통시킨 구성으로 운전자의 부주의로 서비스 브레이크와 파킹 브레이크를 동시에 작동하더라도 에어 스프링 챔버(7)에 항상 일정한 공압만 작용하여 부품의 손상이 방지되어 내구성이 증대된다. 또한, 본 고안은 공압에 의한 것을 예로 설명하였으나 유압에 의한 브레이크장치에도 동일하게 적용될 수 있다.According to the present invention, two pneumatic lines are conventionally used by connecting the service brake valve 3 and the parking brake valve 5 to the pneumatic line 2 from the air tank 1 by using the check valve 4. Compared to the above configuration, the release valve 6 and the quick release valve 9 are installed in the output side pneumatic lines 8 and 12 from the service brake valve 3 and the parking brake valve 5, respectively. Even if the service brake and the parking brake are operated inadvertently by the configuration in communication with the balance line 10, only a constant pneumatic pressure is always applied to the air spring chamber 7, thereby preventing damage to parts and increasing durability. In addition, the present invention has been described by way of example by pneumatic pressure can be equally applied to the brake device by the hydraulic pressure.
