본 발명은 차량용 디스크 브레이크에 관한 것으로, 더욱 상세하게는 캐리어와 패드플레이트의 접촉부위에 오일이 함침된 베어링 메탈을 구비하는 차량용 디스크 브레이크에 관한 것이다.The present invention relates to a disc brake for a vehicle, and more particularly to a disc brake for a vehicle having a bearing metal impregnated with oil at the contact portion of the carrier and the pad plate.

일반적으로 차량용 디스크 브레이크는 차량의 휠과 함께 회전되는 디스크의 양면에 마찰패드를 강제 압착시켜 마찰력을 발생시키고, 이 마찰력을 통해 디스크의 회전을 정지시킴으로써 차량을 제동하는 장치이다. 도 1은 이러한 기능을 하는 종래의 차량용 디스크 브레이크를 도시한 것이다.Generally, a disc brake for a vehicle is a device for braking a vehicle by forcibly compressing friction pads on both sides of a disc rotated together with a wheel of a vehicle to generate a friction force, and stopping the rotation of the disc through the friction force. Figure 1 shows a conventional vehicle disc brake having such a function.

종래 차량용 디스크 브레이크는 도 1에 도시된 바와 같이 캐리어(1)와 패드플레이트(2)사이에는 패드스프링(3)이 설치된다. 패드스프링(3)은 캐리어(1)에 설치되어 패드플레이트(2)의 양측부를 슬라이딩 이동가능하게 지지한다.In the conventional vehicle disc brake, as shown in FIG. 1, a pad spring 3 is installed between the carrier 1 and the pad plate 2. The pad spring 3 is installed in the carrier 1 to support both sides of the pad plate 2 in a slidable manner.

그러나, 이러한 차량용 디스크 브레이크에 있어서, 제동 및 제동 해제시 패드플레이트(2)는 패드스프링(3)의 면을 따라 이동하게 되는데, 이때 패드플레이트(2)와 패드스프링(3)은 서로 접촉이 되어 있으므로, 그 사이의 마찰력이 커 패드플레이트(2)의 슬라이딩 이동이 원활하지 않다는 문제점이 있다.However, in such a disc brake for a vehicle, the pad plate 2 moves along the surface of the pad spring 3 when the brake and the brake are released. In this case, the pad plate 2 and the pad spring 3 come into contact with each other. Therefore, there is a problem that the sliding force of the pad plate 2 is not smooth because the friction force between them is large.

이러한 목적을 달성하기 위하여 본 발명은, 제동 및 제동해제시 패드플레이트가 패드스프링의 면을 따라 원활하게 이동할 수 있게 되며, 패드플레이트의 마찰력을 줄임으로써, 연비향상과 소음감소특성을 갖는 차량용 디스크 브레이크를 제공하는 것이다.In order to achieve the above object, the present invention, when braking and braking release the pad plate can be moved smoothly along the surface of the pad spring, by reducing the friction force of the pad plate, the vehicle disk brake having fuel efficiency improvement and noise reduction characteristics To provide.

이와같은 목적을 달성하기 위한 본 발명은: The present invention for achieving this object is:

차량의 휠과 함께 회전하는 디스크와, 상기 디스크의 양측에 배치되며 그 일면에 마찰패드가 부착된 한쌍의 패드플레이트와, 상기 패드플레이트를 디스크에 접촉되도록 피스톤이 설치된 실린더부를 구비하는 캘리퍼하우징과, 상기 캘리퍼하우 징을 지지하는 캐리어와, 상기 패드플레이트와 상기 캐리어의 사이를 탄성적으로 지지하는 패드스프링을 구비한 차량용 디스크 브레이크에 있어서,A caliper housing having a disk rotating together with a wheel of a vehicle, a pair of pad plates disposed on both sides of the disk, and having a friction pad attached to one surface thereof, and a cylinder portion provided with a piston for contacting the pad plate with the disk; A vehicle disc brake having a carrier for supporting the caliper housing and a pad spring for elastically supporting the pad plate and the carrier,

상기 패드스프링과 접하는 상기 두 플레이트의 접촉면에 차량의 제동과 제동해제시 플레이트의 슬라이딩 마찰력을 줄여 연비향상과 원활한 슬라이딩 및 소음특성을 개선시키는 오일이 함침된 베어링 메탈이 마련된 것을 특징으로 한다.A bearing metal impregnated with oil is provided on the contact surfaces of the two plates in contact with the pad springs to reduce the sliding friction of the plate when braking and releasing the vehicle, thereby improving fuel economy and improving smooth sliding and noise characteristics.

이하에서는 첨부도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention;

본 발명에 따른 디스크 브레이크는 도 2에 도시된 바와 같이 휠(미도시)과 함께 회전하는 디스크(10)의 양측에는 마찰패드(11a,12a)가 부착된 한쌍의 패드플레이트(11,12)를 구비한다. 또한 패드플레이트(11,12)는 차량의 너클부(미도시)에 고정되는 캐리어(13)에 지지된다. 이를 위해 캐리어(13)의 양측에는 패드플레이트(11,12)를 진퇴 가능하게 지지하는 안내부(14)가 형성되고, 두 패드플레이트(11,12)의 양단에는 안내부(14)에 수용되어 걸리는 걸림홈(11b,12b)이 마련된다. 또한 패드플레이트(11,12)의 양단과 이를 지지하는 캐리어(13)의 안내부(14) 사이에는 패드플레이트(11,12)의 진동과 떨림을 방지하는 동시에 걸림홈(11b,12b)의 미끄럼이동을 안내하는 패드스프링(15)이 설치된다. 상기 두 패드플레이트(11,12)의 양단과 캐리어(13)사이에 끼워지는 패드스프링(15)은 소정의 탄성을 가진 얇은 철판이 성형된 것으로, 두 패드플레이트(11,12)를 지지하도록 마련된 양측의 두 지지부(15a,15b)와, 두 지지부의 상단을 연결하는 연결부(15c)로 이루어진다. As shown in FIG. 2, the disc brake includes a pair of pad plates 11 and 12 having friction pads 11a and 12a attached to both sides of the disc 10 rotating together with a wheel (not shown). Equipped. In addition, the pad plates 11 and 12 are supported by the carrier 13 fixed to the knuckle portion (not shown) of the vehicle. To this end, guides 14 are formed on both sides of the carrier 13 to support the pad plates 11 and 12 so as to be retractable, and both ends of the pad plates 11 and 12 are accommodated in the guides 14. Engaging grooves 11b and 12b are provided. In addition, between both ends of the pad plates 11 and 12 and the guide portion 14 of the carrier 13 supporting the pad plates 11 prevents vibration and shaking of the pad plates 11 and 12 while sliding the locking grooves 11b and 12b. The pad spring 15 for guiding the movement is installed. The pad spring 15 fitted between both ends of the two pad plates 11 and 12 and the carrier 13 is formed of a thin iron plate having a predetermined elasticity, and is provided to support the two pad plates 11 and 12. It consists of two support parts 15a and 15b on both sides, and a connection part 15c connecting the upper ends of the two support parts.                     

또한, 캐리어(13)와 접촉하는 상기 두 패드플레이트(11,12)의 걸림홈(11b,12b)에는 오일이 함침된 베어링 메탈(17)이 압입된다.In addition, bearing metals 17 impregnated with oil are press-fitted into the engaging grooves 11b and 12b of the two pad plates 11 and 12 in contact with the carrier 13.

다음에는 이와같이 구성된 차량용 디스크 브레이크의 동작 및 작용효과를 설명한다.Next, the operation and effect of the vehicular disk brake configured as described above will be described.

운전자가 브레이크 패달(미도시)을 밟아 마스터실린더(미도시)에 제동유압이 생성되면, 이 유압이 유압라인을 따라 켈리퍼하우징(미도시)의 실린더부(미도시)로 공급되어 실린더부에 결합된 피스톤(미도시)을 디스크(10)쪽으로 밀어준다. 따라서 두 패드플레이트(11,12)에 부착된 두 마찰패드(11a,12a)가 디스크에 압박되어 마찰패드(11a,12a)와 디스크(10)의 마찰에 의해 제동이 이루어진다.When the driver presses the brake pedal (not shown) to generate braking hydraulic pressure in the master cylinder (not shown), the hydraulic pressure is supplied to the cylinder portion (not shown) of the caliper housing (not shown) along the hydraulic line to be coupled to the cylinder portion. The piston (not shown) to the disk (10). Therefore, the two friction pads 11a and 12a attached to the two pad plates 11 and 12 are pressed against the disk, and braking is performed by friction between the friction pads 11a and 12a and the disk 10.

이와같은 차량용 디스크 브레이크의 제동 및 제동해제시 패드플레이트(11,12)는 패드스프링(15)의 지지부(15a,15b)내에서 이동한다. 이때 패드플레이트(11,12)의 걸림홈(11b,12b)은 오일이 함침된 베어링 메탈(17)이 압입되어 패드플레이트(11,12)는 패드스프링(15)내의 슬라이딩이 원활하게 된다. In braking and releasing braking of the vehicular disk brake, the pad plates 11 and 12 move within the support portions 15a and 15b of the pad spring 15. At this time, the locking grooves 11b and 12b of the pad plates 11 and 12 are press-fitted with bearing metal 17 impregnated with oil, so that the pad plates 11 and 12 slide smoothly in the pad spring 15.

이상에서 상세히 설명한 바와 같이. 본 발명에 따른 차량용 디스크브레이크는 패드플레이트의 걸림홈에 오일이 함침된 베어링 메탈이 압입됨으로써, 패드플레이트의 걸림홈과 패드스프링의 안내부가 접촉하여 슬라이딩할때 패드플레이트의 걸림홈과 패드스프링사이의 마찰력을 줄여 연비향상 및 소음을 줄이는 작용효과가 있다.As detailed above. In the disc brake for a vehicle according to the present invention, a bearing metal impregnated with a locking groove of the pad plate is press-fitted, so that the locking groove of the pad plate and the guide of the pad spring slide between the locking groove of the pad plate and the pad spring. Reduces friction and improves fuel economy and noise.
