Abstract

본 발명은 주차브레이크, 특히 압축공기와 스프링챔버를 이용하는 주차브레이크의 안전장치에 관한 것이다.The present invention relates to a parking brake, in particular a parking brake safety device using compressed air and a spring chamber.

종래에는 주행중 주차용 에어탱크 및 주차용밸브와 릴레이밸브간의 압축계통에 이상 발생시 급제동이 걸렸는바 본 발명을 이를 막기 위하여, 주차용에어탱크에서 릴레이밸브를 통해 스프링챔버를 압축공기로 작동시키는 주차브레이크 시스템에 있어서, 상기 주차용 에어탱크 및 상기 주차용 밸브에서 상기 릴레이밸브에 이르는 압축계통의 이상을 감지하는 저공기압스위치와, 주행중임을 감지하는 속도센서와, 상기 저공기압스위치와 상기 속도 센서의 동시신호에 의하여 점등되는 경고등과, 보조에어탱크와, 상기 동시신호에 의하여 상기 보조에어탱크의 압축공기를 제어하는 마그네틱밸브 및 상기 마그네틱밸브쪽에서 보내지는 압축공기를 스프링챔버 쪽으로 공급할 수 있는 더블첵크밸브를 구비한 주차브레이크의 안전장치이다.Conventionally, a sudden braking was applied when an abnormality occurred in the compression system between the parking air tank and the parking valve and the relay valve while driving. A system, comprising: a low air pressure switch for detecting an abnormality of a compression system from the parking air tank and the parking valve to the relay valve, a speed sensor for detecting driving, and simultaneous operation of the low air pressure switch and the speed sensor A warning lamp illuminated by a signal, an auxiliary air tank, a magnetic valve controlling compressed air of the auxiliary air tank by the simultaneous signal, and a double check valve capable of supplying compressed air sent from the magnetic valve side to the spring chamber. It is a safety device of the equipped parking brake.
