The present invention relates to an electro-hydraulic brake device, which comprises: a pedal master unit for generating hydraulic pressure by pressing a pedal and having a first master chamber and a second master chamber formed therein; a reservoir unit in which a first reservoir and a second reservoir are partitioned to store oil; an electric master unit for detecting the operation of the pedal, and in which a piston reciprocates inside a cylinder to generate hydraulic pressure when the motor is driven, and having a forward chamber formed in a direction in which the piston moves forward, and a reverse chamber formed in a direction in which the piston moves backward; a wheel cylinder unit which provides braking force to front and rear wheels; a storage line unit for guiding oil by connecting the pedal master unit and the reservoir unit; a forward chamber line unit for guiding oil by connecting the first master chamber, the forward chamber, and the wheel cylinder unit; a reverse chamber line unit for guiding oil by connecting the second master chamber, the reverse chamber, and the wheel cylinder unit; and a connection unit for selectively connecting the forward chamber line unit and the reverse chamber line unit to guide the oil. Accordingly, it is possible to reduce the number of valve operations during normal braking.

    본 발명은 전자식 유압 브레이크 장치에 관한 것으로서, 페달의 가압에 의해 유압을 생성하고 제1마스터챔버와 제2마스터챔버가 형성되는 페달마스터부와, 제1리저버와 제2리저버가 구획되어 오일을 저장하는 리저버부와, 페달의 작동을 감지하여 모터가 구동되면, 피스톤이 실린더 내부에서 왕복 이동되어 유압을 생성하고, 피스톤이 전진하는 방향으로 형성되는 전진챔버와, 피스톤이 후진하는 방향으로 형성되는 후진챔버가 구비되는 전동마스터부와, 앞바퀴와 뒷바퀴에 제동력을 제공하는 휠실린더부와, 페달마스터부와 리저버부를 연결하여 오일을 안내하는 저장라인부와, 제1마스터챔버와 전진챔버와 휠실린더부를 연결하여 오일을 안내하는 전진챔버라인부와, 제2마스터챔버와 후진챔버와 휠실린더부를 연결하여 오일을 안내하는 후진챔버라인부와, 전진챔버라인부와 후진챔버라인부를 선택적으로 연결하여 오일을 안내하는 연결부;를 포함하여, 일반 제동시 밸브 작동수를 감소시킬 수 있다.
