본 발명은 디스크 브레이크에 관한 것으로, 캐리어를 이루는 내·외측빔 중에 외측빔의 위치를 캐리어 하중 작용 중심점 상으로 변경함으로써, 캐리어 설치 변형 응력을 최소화하여 그에 따른 내구성을 좋게 하고, 노이즈 발생을 개선 시킬 수 있는 디스크 브레이크에 관한 것이다.The present invention relates to a disc brake, and by changing the position of the outer beam in the inner and outer beams forming the carrier on the center point of the carrier load action, it minimizes the carrier installation strain stress to improve durability and improve noise generation To a disc brake.

일반적으로 디스크 브레이크란 차량의 힐과 동일하게 회전하는 디스크의 양면에 패드가 접촉되어서 차량을 제동하는 것으로서, 이러한 종래의 디스크 브레이크는 대한민국 등록실용신안공보 20-0137140 에 개시되어 있는 바와 같이, 차량의 적소에 캐리어가 고정되고, 캐리어에는 차량과 휠과 결합되어 휠과 동일한 회전 운동을 하는 디스크의 일측이 돌출된다. 그리고, 디스크의 양측면에 접촉되어 디스크의 회전을 멈추게 하는 내,외측 패드가 캐리어에 설치된다. 캐리어의 상측에는 하우징이 슬라이딩 가능하게 결합되는데, 이 하우징에는 피스톤이 내장된 실린더가 마련되어 있다.In general, a disc brake is a brake of a vehicle by pads contacting both sides of a disk rotating in the same way as a heel of the vehicle. Such a conventional disc brake is disclosed in Korean Utility Model Publication No. 20-0137140. The carrier is fixed in place, one side of the disk is coupled to the vehicle and the wheel to the same rotational motion as the wheel protrudes. In addition, inner and outer pads are provided in the carrier to contact both sides of the disk to stop the rotation of the disk. A housing is slidably coupled to the upper side of the carrier, and the housing is provided with a cylinder with a built-in piston.

또, 패드가 캐리어와 저항없이 왕복 운동 되도록 하는 패드 스프링이 패드와 캐리어 사이에 마련된다.In addition, a pad spring is provided between the pad and the carrier to allow the pad to reciprocate without resistance with the carrier.

이의 작용을 간단히 설명하면 브레이크 페달을 밟으면 실린더에 내장된 피스톤이 내측 패드의 디스크 쪽으로 밀고 내측 패드가 디스크와 접촉하게 되어 더 이상 디스크 측으로 이동될 수 없어도 피스톤은 내측 패드를 계속하여 밀고 있으므로, 하우징 자체가 이동하게 된다. 즉 캐리어는 차체에 고정되어 있고, 하우징은 캐리어에 슬라이딩 가능하게 결합되어 있으므로 하우징은 내측 패드 쪽으로 이동된다. 하우징이 내측 패드 쪽으로 이동되면서 캐리어에 안치된 외측 패드를 디스크 측으로 이동시켜 외측 패드가 디스크에 접촉하게 되는 것이다.In brief, when the brake pedal is pressed, the piston built into the cylinder is pushed toward the disk of the inner pad and the inner pad is brought into contact with the disk so that the piston continues to push the inner pad even when it can no longer be moved to the disk. Will be moved. In other words, the carrier is fixed to the vehicle body and the housing is slidably coupled to the carrier so that the housing is moved toward the inner pad. As the housing is moved toward the inner pad, the outer pad placed in the carrier is moved to the disk side so that the outer pad contacts the disk.
