유압 브레이크 장치에 관한 발명이 개시된다. 본 발명에 따른 유압 브레이크 장치는: 오일을 토출하는 펌프; 펌프와 제1유로로 연통되고, 펌프로부터 토출되는 오일의 압력 맥동을 감소시키는 맥동저감부; 및 펌프와 제2유로로 연통되고, 펌프로부터 토출되는 오일을 차륜으로 전달하는 차륜전달부를 포함하고, 맥동저감부는, 내부 공간이 형성되는 바디부; 바디부에 고정되고, 제1유로로부터 유입되는 오일에 의해 팽창되며 오일의 압력 맥동을 감소시키는 댐퍼부; 댐퍼부를 감싸고, 바디부의 내부 공간 상에서 이동되며, 댐퍼부의 팽창을 제한하는 플런저부; 및 차량의 제동 여부에 따라 플런저부를 작동시키는 가압부를 포함하는 것을 특징으로 한다.

    According to the present invention, a hydraulic brake apparatus is disclosed. According to the present invention, the hydraulic brake apparatus comprises: a pump discharging oil; a pulsation reduction unit communicating with the pump with a first flow path, and configured to reduce pressure pulsation of the oil discharged from the pump; and a wheel transmission unit communicating with the pump with a second flow path, and configured to transfer the oil discharged from the pump to a wheel. The pulsation reduction unit comprises: a body unit having an internal space formed therein; a damper unit fixated to the body unit, expanded by the oil flowing from the first flow path, and reducing pressure pulsation of the oil; a plunger unit surrounding the damper unit, moving in the internal space of the body unit, and limiting expansion of the damper unit; and a pressurization unit operating the plunger unit according to whether a vehicle is braked.
