액압 공급장치가 개시된다. 본 발명의 일 측면에 따르면, 내부에 제동유압의 조절을 위한 유로 및 밸브가 마련되는 모듈레이터블록에 결합되고, 고정자와 회전자를 구비하는 모터; 상기 회전자와 결합되고, 상기 회전자와 함께 회전 운동하는 회전축; 일측에 피스톤이 결합되고, 상기 회전축과 동일축 상에서 볼스크류 방식으로 연결되어 상기 회전축의 회전 운동을 직선 운동으로 변환하는 볼너트; 상기 회전축과 볼너트가 함께 회전하는 것을 방지하는 회전방지부; 및 상기 회전축에 결합되어 상기 회전축의 회전량을 측정하는 센서조립체;를 포함하는 액압 공급장치가 제공될 수 있다.

    Disclosed is a hydraulic supply apparatus. According to one aspect of the present invention, the hydraulic pressure supply apparatus may be provided, and comprises: a motor coupled to a modulator block having a flow path and a valve for controlling a brake hydraulic pressure therein, and having a stator and a rotor; a rotary shaft coupled to the rotor and rotating with the rotor; a ball nut having a piston coupled to one side and connected in a ball screw manner on the same axis as the rotary shaft to convert a rotational motion of the rotary shaft into a linear motion; a rotation preventing unit preventing the rotary shaft and the ball nut from rotating together; and a sensor assembly coupled to the rotary shaft to measure an amount of rotation of the rotary shaft. The hydraulic supply apparatus according to an embodiment of the present invention has a simple structure so that a magnet for a motor position sensor can be installed.
