Abstract

본 발명은 비상용 브레이크장치에 관한 것으로, 마스터 실린더(20)와 휠 실린더(40) 사이의 브레이크 파이프(30)에는 오일압 감지센서(50)가 설치되고, 휠 실린더(40)측에는 3 웨이 밸브(60)가 설치되며, 3 웨이 밸브(60)의 3포트(P1, P2, P3)에는 각각 휠 실린더(40), 기존의 브레이크 파이프(30), 신설된 브레이크 파이프(70)가 접속되며, 신설된 브레이크 파이프(70)의 타단에는 엔진(E)에 의하여 구동되는 오일펌프(80)가 접속된 것으로, 본 발명에 의하면 브레이크장치에서 누유에 의한 제동력의 이상발생시 이를 보완하여 안정적인 제동력을 얻을 수 있으므로, 주행중 브레이크의 불량동작으로 인한 사고를 방지할 수 있다.An oil pressure detection sensor (50) is provided on a brake pipe (30) between a master cylinder (20) and a wheel cylinder (40), and a three - way valve Wheel cylinders 40, a conventional brake pipe 30, and a newly installed brake pipe 70 are connected to the three ports P1, P2, and P3 of the three-way valve 60, The oil pump 80 driven by the engine E is connected to the other end of the brake pipe 70. According to the present invention, when an abnormality of the braking force due to oil leakage occurs in the brake apparatus, , It is possible to prevent an accident caused by a defective operation of the brake during traveling.
