Abstract
본 발명은 유압식 브레이크의 마스터 실린더와 휘일 실린더 사이에 액압 제어밸브가 제공되어 있는 전자 제어 브레이크용 유압 작동기가 장착된 유압식 브레이크에 관한 것으로, 상기 유압 브레이크의 구조를 개선하여 제동초기에 마스터 실린더의 액압이 휘일 실린더에 직접 연결되므로써 제동초기의 브레이크 작동지연을 해소시키는 것을 목적으로 하며, 이를 위하여, 본 발명은, 브레이크 페달을 밟으면 상부에 장착된 리저버로부터의 오일에 의해 유압이 발생되는 마스터 실린더와, 그 유압을 받아 브레이크 슈를 드럼에 밀어 붙여 제동력을 발생시키는 휘일 실린더 및 유로를 형성하는 브레이크 파이프 및 호스를 포함하는 전자 제어 브레이크용 유압작동기가 장착된 유압식 브레이크에 있어서, 상기 마스터 실린더와 휘일 실린더의 사이 및 리저버와 액압원으로서의 펌프 사이에는 밸브 하우징, 파이롯 밸브, 모터 ,반력핀 및 반력실을 포함하는 액압 제어 밸브가 제공되는 것을 특징으로 한다.The present invention relates to a hydraulic brake equipped with a hydraulic actuator for an electronically controlled brake provided with a hydraulic control valve between a master cylinder and a wheel cylinder of a hydraulic brake. The hydraulic brake of the master cylinder is improved by improving the structure of the hydraulic brake. It is an object of the present invention to eliminate the brake operation delay of the initial braking by being directly connected to the wheel cylinder. To this end, the present invention provides a master cylinder in which hydraulic pressure is generated by oil from an upper mounted reservoir when the brake pedal is pressed; A hydraulic brake equipped with a hydraulic actuator for an electronically controlled brake, comprising a brake cylinder and a hose forming a wheel cylinder and a flow path for receiving a hydraulic pressure and pushing a brake shoe to a drum to generate a braking force. Between and reservoir And a hydraulic pressure control valve including a valve housing, a pilot valve, a motor, a reaction pin, and a reaction chamber between the pump and the pump as the hydraulic pressure source.
