Abstract

본 발명은 브레이크 배압 장치에 관한 것으로 특히, 파워 스티어링의 유압을 이용하여 브레이크 배압 장치를 구성함으로서 보통의 브레이크 배압 장치를 구성하는 부스터의 사용을 없애 브레이크 배압 장치가 차지하는 공간을 축소하고, 비교적 간단한 배압장치를 구성하여 브레이크 배압 장치의 제작 단가를 낮출 수 있도록 하기 위하여 브레이크 페달측 피스톤 로드의 작동 영향을 받아 가감압을 바퀴측에 작용시키는 마스터 실린더와, 상기 마스터 실린더내를 움직이는 피스톤 로드에 종속되는 작동성을 갖는 밸브 작동 로드와, 상기 밸브 작동 로드의 움직임에 의해 외부측 유압을 마스터 실린더 내로 유도하는 밸브 개폐 기구부와, 상기 밸브 개폐 기구부측에 파워 스티어링측 유압을 공급하기 위해 밸브개폐 기구부에 포함되는 유압 파이프라인과, 상기 마스터 실린더 측으로의 유압 공급 여부에 따라 피스톤을 복귀시키는 리턴 스프링을 포함하는 브레이크 배압 장치를 제공한 것이다.The present invention relates to a brake back pressure device, and in particular, by configuring the brake back pressure device using the hydraulic pressure of the power steering, eliminating the use of the booster constituting the normal brake back pressure device, thereby reducing the space occupied by the brake back pressure device, and relatively simple back pressure. In order to reduce the manufacturing cost of the brake back pressure device by configuring the device, the operation is dependent on the master cylinder which acts on the wheel side under the influence of the operation of the piston rod on the brake pedal side, and the piston rod moving in the master cylinder. And a valve opening and closing mechanism for guiding external hydraulic pressure into the master cylinder by the movement of the valve operating rod, and a valve opening and closing mechanism for supplying power steering side hydraulic pressure to the valve opening and closing mechanism. With hydraulic pipeline, It provides a brake back pressure device including a return spring for returning the piston depending on whether or not the hydraulic supply to the master cylinder side.
