The present invention relates to a hydraulic brake apparatus for a motorcycle. According to the present invention, the hydraulic brake apparatus for a motorcycle comprises: a master cylinder (10) transferring oil of an oil tank (14) to a caliper (20) installed on a front wheel while moving a push rod (13) by an operation of a lever (12), and returning the push rod (13) to its initial status through a return spring (15); and pistons (22) installed on both sides of the caliper (20), and controlling the rotation by pushing both sides of a front wheel disc (30) by a front end pad (23) through an oil pressure transferred through the master cylinder (10). On one side of the body of the caliper (20), an oil pressure buffer machine (100) is presented for instantaneously resolving the oil pressure in an oil chamber formed in the caliper (20). The present invention is able to, when a brake is generated on the front wheel with the hydraulic brake apparatus applied to the motorcycle, a hydraulic buffering force is applied in multiple stages, and the brake is controlled slowly, and the vehicle body can be prevented from overturning in accordance with the control of inertia.

    본 발명은 이륜차용 유압 브레이크 장치에 관한 것이다. 본 발명은 레버(12) 동작에 따른 푸시로드(13)가 이동하면서 오일탱크(14)의 오일을 전륜에 설치된 캘리퍼(20)로 전달하며 리턴스프링(15)을 통해 푸시로드(13)를 초기 상태로 복귀시키는 마스터실린더(10)와 상기 캘리퍼(20)의 양쪽에 설치되어 상기 마스터실린터(10)를 통해 전달되는 오일 압력을 통해 선단 패드(23)로 전륜 디스크(30)의 양쪽을 밀어 회전을 제어하는 피스톤(22)으로 이루어지는 이륜차용 브레이크 장치에 있어서, 상기 캘리퍼(20)의 바디 일측에, 상기 캘리퍼(20)에 형성된 오일실내의 오일압력이 순간적으로 해소될 수 있도록 오일압력 완충기(100)를 제시한다. 본 발명은 이륜차에 적용된 상태에서 주행중 전륜에 브레이크가 발생되는 경우 유압 완충력이 다단으로 작동되면서 서서히 제어되도록 하여 관성력 제어에 따른 차체의 전도를 방지할 수 있도록 하는 장점이 있다.
