In general, a disc brake for a vehicle is a device that obtains a braking force by pressing a portion of a disk-shaped disk that rotates together with a wheel with a friction pad on both sides, and is coupled to the vehicle body as shown in FIG. The carrier 10 is installed to be spaced apart from each other by a predetermined distance (11), the piston 10 is provided on one side so as to move forward and backward on the carrier 10 and to press the two friction pads 11 with the disk (D). It includes a caliper housing 20 is provided with a cylinder portion 20a which is installed to move forward and backward and the finger portion 20b is provided on the other side.

However, in such a conventional disc brake for a vehicle, when the electric power supply to the electric motor is cut off due to battery discharge or electric wire short-circuit while the parking brake function is being performed, a dedicated tool is used after disassembling the wheel of the vehicle. There is a problem that the parking brake function is released only when the operating shaft is rotated so that the vehicle can move.

상술한 바와 같이 본 발명에 따른 차량용 디스크 브레이크는 전기모터에 전기가 직접 공급될 전기모터에 전원입력단자가 마련되어 외부의 전원공급유닛을 통해 전기모터에 직접 전기를 공급할 수 있게 되므로, 주차 브레이크 기능을 용이하게 해제시킬 수 있게 되는 효과가 있다. As described above, the disc brake for a vehicle according to the present invention is provided with a power input terminal in an electric motor to which electricity is directly supplied to the electric motor, so that the disc brake can be directly supplied to the electric motor through an external power supply unit. There is an effect that can be easily released.

본 발명에 따른 디스크 브레이크는 도 2에 도시한 바와 같이, 차체에 고정 설치되는 캐리어(10)와, 캐리어(10)에 이동 가능하게 결합되는 캘리퍼 하우징(20)을 포함한다. As shown in FIG. 2, a disc brake according to the present invention includes a carrier 10 fixed to a vehicle body and a caliper housing 20 movably coupled to the carrier 10.

캐리어(10) 내에는 차량의 휠과 함께 회전하는 디스크(D)와 마찰하는 한 쌍의 마찰패드(11)가 진퇴이동 가능하게 설치되어 있으며, 한 쌍의 마찰패드(11)는 서로 이격되게 설치되어 사이에 디스크(D)가 배치되도록 되어 있다. 따라서, 마찰패드(11)가 디스크(D)를 향하여 진퇴이동하며 제동이 이루어진다. In the carrier 10, a pair of friction pads 11, which friction with the disk D rotating together with the wheel of the vehicle, are installed to move forward and backward, and the pair of friction pads 11 are spaced apart from each other. The disk D is arranged between them. Therefore, the friction pad 11 moves forward and backward toward the disk D and braking is performed.

캘리퍼 하우징(20)의 일측에는 전달된 유압에 따라 진퇴이동하며 한 쌍의 마찰패드(11) 중 어느 하나의 마찰패드(11)를 디스크(D)측으로 전진시켜 마찰패드(11)가 디스크(D)와 마찰하게 하는 피스톤(21)이 설치되어 있으며, 캘리퍼 하우징(20)의 타측에는 다른 하나의 마찰패드(11)를 디스크(D)측으로 전진시켜 마찰패드(11)가 디스크(D)와 마찰하게 하는 핑거부(20b)가 형성되어 있다. One side of the caliper housing 20 is moved back and forth in accordance with the transmitted hydraulic pressure and the friction pad 11 of any one of the pair of friction pads 11 is advanced to the disk D side, so that the friction pad 11 is the disk D. Piston 21 is provided to friction with), the other side of the caliper housing 20, the other friction pad 11 is advanced to the disk (D) side friction pad 11 friction with the disk (D) The finger portion 20b is formed.

Therefore, the piston 21 advances to the disk D side by the hydraulic pressure transmitted during braking and presses the one friction pad 11 to the disk D, and acts between the piston 21 and the one friction pad 11. By the reaction force, the caliper housing 20 moves in a direction opposite to the direction in which the piston 21 moves, so that the finger portion 20b provided on the other side of the caliper housing 20 receives the other friction pad 11 from the disk ( Braking is achieved by the frictional force acting between the two friction pads 11 and the disk D by pressing against D).

또한, 본 발명에 따른 차량용 디스크 브레이크는 주차 브레이크 기능을 수행할 수 있도록 주차장치(30)를 포함한다. 주차장치(30)는 캘리퍼 하우징(20)의 실린더부(20a) 내에 회전 가능하게 설치된 작동축(31)과, 작동축(31)의 회전방향에 따라 진퇴이동 하며 피스톤(21)을 가압하거나 가압 해제하도록 피스톤(21)의 내측에 설치되는 가압슬리브(32)와, 작동축(31)을 회전시키기 위한 전기모터(33)와, 다수 의 기어(34a, 34b)를 포함하여 전기모터(33)의 회전축(33a)에서 발생한 동력을 작동축(31)에 전달하되, 그 회전수를 감소시켜 전달하는 감속기어조립체(34)를 포함한다. In addition, the disk brake for a vehicle according to the present invention includes a parking lot 30 to perform a parking brake function. The parking lot 30 has an operating shaft 31 rotatably installed in the cylinder portion 20a of the caliper housing 20, and moves forward and backward according to the rotational direction of the operating shaft 31 to pressurize or pressurize the piston 21. An electric motor 33 including a pressure sleeve 32 installed inside the piston 21, an electric motor 33 for rotating the operation shaft 31, and a plurality of gears 34a and 34b so as to be released.
