Abstract

본 발명은 자동차의 안티-로크 브레이크 시스템을 개시한다. 개시된 본 발명은, 마스터 실린더(2)에서 발생되어 각 차륜(8)에 장착된 브레이크 본체(9)로 전달되는 유압의 이동라인(10)에 형성되고, 끝단이 다시 상기 차륜(8)에 연결되도록 폐로(페로)구조로 이루어져, 브레이크 본체(9)의 유압이 토출되는 분기라인(10a); 상기 분기라인(10a)에 설치되어, 유압의 토출량을 제어하는 압력 조절용 솔레노이드 밸브(20); 상기 압력 조절용 솔레노이드 밸브(20)의 개도량을 차륜(8)의 회전속도에 따라 제어하는 전자 제어 유니트(12); 상기 전자 제어 유니트(12)에 의해 제어되고 상기 분기라인(10a)을 통해 유압을 강제압송시키기 위한 진공압을 제공하는 진공펌프(16); 및 상기 진공펌프(16)에 의해 강제압송된 유압이 일시적으로 저장되는 어큐뮬레이터(18)를 포함하는 것을 특징으로 한다.The present invention discloses an anti-lock brake system of a motor vehicle. The disclosed invention is formed in the hydraulic movement line 10 generated in the master cylinder 2 and delivered to the brake body 9 mounted on each wheel 8, the end of which is connected to the wheel 8 again. Branch line (10a) is made of a closed (ferro) structure so as to discharge the hydraulic pressure of the brake body (9); A pressure adjusting solenoid valve (20) installed in the branch line (10a) to control a discharge amount of hydraulic pressure; An electronic control unit 12 controlling the opening amount of the pressure regulating solenoid valve 20 according to the rotational speed of the wheel 8; A vacuum pump (16) controlled by the electronic control unit (12) and providing a vacuum pressure for forcing hydraulic pressure through the branch line (10a); And an accumulator 18 in which the hydraulic pressure forcedly pushed by the vacuum pump 16 is temporarily stored.
