Abstract

본 발명은, 비상 브레이크 주 도관을 통해 비상 브레이크 압력 소스로부터 공급될 수 있는 휠 브레이크와, 동력원 및 동력원과 적어도 한 휠 브레이크사이에서 브레이크 압력이 발생되어 동력원으로부터의 압력 매체를 사용하여 감소될 수 있는 적어도 하나의 밸브 장치를 갖는 동력 보조 브레이크 디바이스를 구비하는, 페달에 의해 작동될 수 있는 이중-회로 비상 브레이크 압력 소스를 갖는 차량 유압 브레이크 시스템에 관한 것이다. 적어도 하나의 밸브 장치는 비상 브레이크 압력 소스와 휠 브레이크 상이에 설치되며, 비상 브레이크 작동시 이 밸브 장치는 비상 브레이크 압력 소스를 휠 브레이크에 접속시키는, 동력 보조 브레이크 작동시 비상 브레이크 압력 소스를 휠 브레이크로부터 분리시킨다.
이러한 밸브 장치(29,30)는 동력 보조 브레이크 작동시 휠 브레이크로부터 배출되어야 하는 압력 매체가 비상 브레이크 주 도관(12,13)과 복귀 도관(59)을 통해 비상 브레이크 압력 소스(6)의 저장실(7)로 빠져나가도록 설계된다. 이러한 밸브 장치(29,30)는 미세한 제어력에 의해 제어될 수 있으며 비용이 저렴하다.
본 차량 브레이크 시스템은 자동차에 적합하다.
