본 발명은 차량용 디스크 브레이크에 관한 것으로, 더욱 상세하게는 캐리어와 캐리어에 이동가능하게 설치되는 패드플레이트를 구비한 차량용 디스크 브레이크에 관한 것이다. The present invention relates to a vehicle disc brake, and more particularly, to a vehicle disc brake having a carrier and a pad plate movably mounted to the carrier.                         

일반적으로 차량용 디스크 브레이크는 휠과 함께 회전하는 원판형의 디스크 일부를 양쪽에서 마찰패드로 강하게 압박하여 제동력을 얻는 장치로써, 종래의 차량용 디스크 브레이크는 도 1에 도시되어 있는 바와 같이, 마찰패드(4a)가 부착된 한 쌍의 패드플레이트(4)가 서로 일정간격 이격되게 내부에 설치되며 차체에 결합되는 캐리어(2)와, 캐리어(2)에 슬라이딩 가능하게 결합되며 두 패드플레이트(4)를 디스크(1)로 압박할 수 있도록 일측에 피스톤(3a)이 설치되는 실린더부(3b)와 타측에 핑거부(3c)가 마련된 캘리퍼하우징(2)을 구비한다. In general, a vehicle disc brake is a device for obtaining a braking force by pressing a portion of a disk-shaped disk that rotates with the wheel with a friction pad on both sides, the conventional vehicle disc brake, as shown in Figure 1, the friction pad (4a) A pair of pad plates (4) attached to each other are installed in a spaced space apart from each other, and the carrier (2) is coupled to the vehicle body, and the two pad plates (4) are slidably coupled to the carrier (2). It is provided with the cylinder part 3b in which the piston 3a is provided in one side, and the caliper housing 2 in which the finger part 3c was provided in the other side so that it may press by (1).

따라서 제동유압이 전달되면 캘리퍼하우징(2)의 피스톤(3a)과 핑거부(3c)가 두 패드플레이트(4)를 디스크(1)의 양측으로 각각 압박하여 마찰패드(4a)와 디스크(1)의 마찰에 의해 제동력을 얻는다. Accordingly, when the braking hydraulic pressure is transmitted, the piston 3a and the finger portion 3c of the caliper housing 2 press the two pad plates 4 to both sides of the disk 1, respectively, so that the friction pad 4a and the disk 1 Braking force is obtained by friction.

이와 같이 패드플레이트(4)가 슬라이딩 가능하게 캐리어(2)에 설치될 수 있도록 패드플레이트(4)에는 설치돌기(4b)가 마련되고, 캐리어(2)에는 설치돌기(4b)를 슬라이딩 이동가능하게 수용하는 설치홈(2a)이 마련되어, 설치돌기(4b)가 설치홈(4b)의 면을 따라 미끄러지며 이동할 수 있게 되어 있는 것이다. In this way, the mounting plate 4b is provided on the pad plate 4 so that the pad plate 4 can be slidably installed on the carrier 2, and the mounting protrusion 4b is slidably movable on the carrier 2. The installation groove 2a which accommodates is provided, and the installation protrusion 4b is able to slide along the surface of the installation groove 4b, and to move.

그런데 이러한 차량용 디스크 브레이크에 있어서, 전술한 바와 같이 제동 및 제동해제 시 패드플레이트(4)의 설치돌기(4b)가 캐리어(2)의 설치홈(2a) 면을 슬라이딩하며 이동한다. 이 때, 설치돌기(4b)와 설치홈(2a)은 서로 면접촉하고 있으므로 슬라이딩시 그 사이에서 작용하는 마찰력이 크다. 따라서 패드플레이트(4)의 슬라이딩 이동은 원활하지 않다는 문제점이 있다. However, in the disc brake for a vehicle, as described above, the mounting protrusion 4b of the pad plate 4 moves while sliding the surface of the mounting groove 2a of the carrier 2 when braking and releasing the braking. At this time, since the installation protrusion 4b and the installation groove 2a are in surface contact with each other, the frictional force acting between them is large. Therefore, there is a problem that the sliding movement of the pad plate 4 is not smooth.

본 발명은 이러한 문제를 해결하기 위한 것으로, 그 목적은 패드플레이트가 캐리어 내에서 원활하게 슬라이딩 이동할 수 있도록 되어 있는 차량용 디스크 브레이크를 제공하는 것이다.  The present invention has been made to solve this problem, and an object thereof is to provide a disc brake for a vehicle in which the pad plate can be slid and moved smoothly in the carrier.

이와 같은 목적을 달성하기 위한 본 발명은, The present invention for achieving such an object,

내부에 마찰패드가 부착된 한 쌍의 패드플레이트가 슬라이딩 가능하게 설치되며 차체에 고정된 캐리어와, 상기 캐리어에 슬라이딩 가능하게 설치된 캘리퍼하우징과, 상기 캐리어의 내측 양단부와 상기 패드플레이이트의 양단부 중 어느 하나에 오목하게 마련된 설치홈과, 다른 하나로부터 돌출형성되어 상기 설치홈에 슬라이딩 이동가능하게 수용되는 설치돌기를 구비한 차량용 디스크 브레이크에 있어서, 상기 설치홈과 상기 설치돌기 중 어느 하나에는 슬라이딩 돌기가 구비되어 상기 슬라이딩 돌기를 통해 상기 설치홈과 상기 설치돌기가 접촉하도록 되어 있다.A pair of pad plates having a friction pad attached therein is slidably installed and fixed to a vehicle body, a caliper housing slidably mounted to the carrier, an inner end of the carrier and both ends of the pad plate. In a disc brake for a vehicle having an installation recess provided in one concave, and an installation protrusion protruding from the other and slidably accommodated in the installation groove, one of the installation groove and the installation projection is a sliding projection. It is provided to be in contact with the installation groove and the installation projection through the sliding projection.

또한, 상기 슬라이딩돌기는 상기 캘리퍼하우징의 슬라이딩방향으로 길게 형성된다. In addition, the sliding protrusion is formed long in the sliding direction of the caliper housing.

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

본 발명에 따른 디스크 브레이크는 도 2에 도시되어 있는 바와 같이 휠(미도시)과 함께 회전하는 디스크(10)의 일부를 마찰패드(41a, 41b)가 부착된 패드플레이트(40a, 40b)로 압박하여 마찰패드(41a, 41b)와 디스크(10)의 마찰에 의해 제동력을 얻는 장치로써, 차체에 고정설치되는 캐리어(20)와, 캐리어(20)에 슬라이딩 가능하게 결합되는 캘리퍼하우징(30)을 갖추고 있다.The disc brake according to the present invention presses a part of the disk 10 which rotates together with a wheel (not shown) to the pad plates 40a and 40b to which the friction pads 41a and 41b are attached, as shown in FIG. 2. To obtain a braking force by friction between the friction pads 41a and 41b and the disk 10, the carrier 20 fixed to the vehicle body and the caliper housing 30 slidably coupled to the carrier 20. Equipped.

캘리퍼하우징(30)의 일측에는 실린더부(31)가 마련되어 있어, 실린더부(31) 내에 설치되어 유압에 따라 진퇴이동하며 일측 패드플레이트(40a)를 디스크(10)에 압박하는 피스톤(32)을 설치할 수 있게 되어 있으며, 캘리퍼하우징(30)의 타측에는 핑거부(33)가 마련되어 캘리퍼하우징(30)의 슬라이딩 이동과 함께 타측 패드플레이트(40b)를 디스크(10)에 압박할 수 있게 되어 있다. One side of the caliper housing 30 is provided with a cylinder portion 31, the piston 32 is installed in the cylinder portion 31 to move back and forth according to the hydraulic pressure and to press the pad plate 40a on the disk 10 to one side. The other side of the caliper housing 30 is provided with a finger portion 33 is provided so as to press the other pad plate 40b to the disk 10 with the sliding movement of the caliper housing 30.

이러한 차량용 디스크 브레이크에 있어서, 캐리어(20) 내측 양단부에는 두 패드플레이트(40a, 40b)를 설치할 수 있도록 오목하게 설치홈(21)이 마련된다. 설치홈(21)은 캐리어(20) 내측 양단부에 서로 마주보며 대응하도록 오목하게 형성되며 두 패드플레이트(40a, 40b)가 나란히 설치될 수 있도록 내측 양단에 각각 한 쌍씩 마련된다. In such a disc brake for a vehicle, mounting grooves 21 are recessed in both ends of the inner side of the carrier 20 so as to install two pad plates 40a and 40b. The installation grooves 21 are formed in a concave shape so as to face each other at both ends of the inner side of the carrier 20 and are provided in pairs at both ends of the inner side so that the two pad plates 40a and 40b can be installed side by side.

한편, 패드플레이트(40a, 40b)에는 캐리어(20)의 설치홈(21)에 끼워 설치될 수 있도록 양단에 설치돌기(42a, 42b)가 돌출형성된다. On the other hand, the mounting plate (42a, 42b) is formed on both ends of the pad plate (40a, 40b) so as to be fitted into the installation groove 21 of the carrier 20.

이러한 캐리어(20)의 설치홈(21)과 패드플레이트(40a, 40b)의 설치돌기(42a, 42b) 사이에는 패드플레이트(40a, 40b)를 캐리어(20)에 이동가능하게 지지하는 패드스프링(50)이 설치된다. 패드스프링(50)에는 판상의 부재를 밴딩하여 형성되며 그 중도에 대략 "ㄷ"자형상으로 이루어진 슬라이딩부(51)가 마련되어 슬라이딩부(51)가 캐리어(20)의 설치홈(21)과 패드플레이트(40a, 40b)의 설치돌기(42a, 42b) 사이에 끼워진다. 따라서 설치돌기(42a, 42b)는 슬라이딩부(51)에 슬라이딩 가능하게 수용되어 유압에 따라 진퇴운동 한다. Between the mounting groove 21 of the carrier 20 and the mounting protrusions 42a and 42b of the pad plates 40a and 40b, the pad spring 40 supports the pad plates 40a and 40b to be movable on the carrier 20. 50) is installed. The pad spring 50 is formed by bending a plate-like member, and a sliding part 51 having a substantially "c" shape is provided in the middle of the pad spring 50, and the sliding part 51 is provided with the mounting groove 21 and the pad of the carrier 20. It fits in between the mounting protrusions 42a and 42b of the plates 40a and 40b. Therefore, the installation protrusions 42a and 42b are slidably accommodated in the sliding part 51 to move forward and backward according to the hydraulic pressure.                     

또한, 설치돌기(42a, 42b)의 슬라이딩부(51)와 접촉하는 단부에는 도 3과 4에 도시되어 있는 바와 같이 접촉면적을 감소시킬 수 있도록 슬라이딩돌기(43)가 마련되어 있다. 슬라이딩돌기(43)는 설치돌기(42a, 42b)의 측면과 상하측 면에 배치되어, 그 끝단만이 패드스프링(50)의 슬라이딩부(51)와 접촉한다. 따라서 설치돌기(42a, 42b)와 패드스프링(50)의 접촉면적을 대폭 축소할 수 있게 되는 것이다. In addition, sliding end portions 43 are provided at ends of the installation protrusions 42a and 42b in contact with the sliding portions 51 so as to reduce the contact area as shown in FIGS. 3 and 4. Sliding protrusions 43 are disposed on the side and upper and lower surfaces of the installation projections (42a, 42b), only the end thereof contacts the sliding portion 51 of the pad spring (50). Therefore, the contact area between the installation protrusions 42a and 42b and the pad spring 50 can be greatly reduced.

슬라이딩돌기(43)는 유압이 전달되어 패드플레이트(40a, 40b)가 슬라이딩 이동할 때, 패드플레이트(40a, 40b)가 기울어짐 없이 슬라이딩부(51)의 면을 따라 수평하게 이동할 수 있도록 슬라이딩 방향으로 길게 형성되며, 패드스프링(50)의 패드플레이트(40a, 40b)를 지지하는 힘이 설치돌기(42a, 42b)에 골고루 분산될 수 있도록 다수개가 나란히 일정 간격으로 배치된다. When the hydraulic pressure is transmitted and the pad plates 40a and 40b slide, the sliding protrusions 43 slide in the sliding direction so that the pad plates 40a and 40b can move horizontally along the surface of the sliding part 51 without tilting. It is formed long, and a plurality of the springs are arranged side by side at regular intervals so that the force supporting the pad plates 40a and 40b of the pad spring 50 can be evenly distributed to the installation protrusions 42a and 42b.

또한, 슬라이딩돌기(43)는 그 끝단이 슬라이딩부(51)의 면을 따라 원활하게 슬라이딩 이동할 수 있도록 곡면으로 이루어진다. In addition, the sliding protrusion 43 is formed of a curved surface so that the end thereof can smoothly move along the surface of the sliding portion 51.

본 실시예에서는 설치돌기(42a, 42b)는 패드플레이트(40a, 40b)에, 설치홈(21)은 캐리어(20)에 설치되어 있는 차량용 디스크 브레이크가 개시되어 있으나, 반대로 설치돌기를 캐리어에, 설치홈을 패드플레이트에 마련하는 것도 가능하다. In the present embodiment, although the mounting protrusions 42a and 42b are provided on the pad plates 40a and 40b, and the mounting groove 21 is installed on the carrier 20, a vehicle disc brake is disclosed. It is also possible to provide an installation groove in the pad plate.

또한, 본 실시예에서 패드플레이트(40a, 40b)는 패드스프링(50)을 통해 캐리어(20)에 설치되어 있으나, 패드스프링 없이 패드플레이트(40a, 40b)를 캐리어(20)의 설치홈(21)에 직접 설치하는 구성도 가능하다. In addition, in the present embodiment, the pad plates 40a and 40b are installed in the carrier 20 through the pad springs 50, but the pad plates 40a and 40b are installed in the carrier 20 without the pad springs. It is also possible to install directly on).

다음에는 이와 같이 구성된 차량용 디스크 브레이크의 동작 및 작용효과를 도면을 참조하여 상세히 설명한다. Next, the operation and effect of the vehicular disk brake configured as described above will be described in detail with reference to the accompanying drawings.

자동차의 주행 중 운전자가 브레이크 페달(미도시)을 밟으면 마스터 실린더(미도시)에서 제동유압이 형성되고 마스터 실린더(미도시)에서 형성된 제동유압은 캘리퍼하우징(30)에 전달된다. When the driver presses a brake pedal (not shown) while driving the vehicle, a braking hydraulic pressure is formed in the master cylinder (not shown), and the braking hydraulic pressure formed in the master cylinder (not shown) is transmitted to the caliper housing 30.

이러한 제동유압에 의해 캘리퍼하우징(30)의 일측에 마련된 실린더부(31)의 피스톤(32)은 일측 패드플레이트(40a)를 향하여 전진하면서 일측 패드플레이트(40a)를 디스크(10)에 압박한다. 또한 제동유압에 의해 캘리퍼하우징(30)은 퇴진하고 그에 따라 캘리퍼하우징(30)의 타측에 마련되어 있는 핑거부(33)가 타측 패드플레이트(40b)를 디스크(10)에 압박한다. 따라서 두 패드플레이트(40a, 40b)에 부착된 두 마찰패드(41a, 41b)가 디스크(10)에 압박되어 마찰패드(41a, 41b)와 디스크(10)의 마찰에 의해 제동이 일어난다. By the braking hydraulic pressure, the piston 32 of the cylinder part 31 provided on one side of the caliper housing 30 presses the one side pad plate 40a to the disk 10 while advancing toward the one side pad plate 40a. In addition, the caliper housing 30 is retracted by the braking hydraulic pressure, so that the finger part 33 provided on the other side of the caliper housing 30 presses the other pad plate 40b to the disk 10. Therefore, the two friction pads 41a and 41b attached to the two pad plates 40a and 40b are pressed against the disk 10 and braking is caused by friction between the friction pads 41a and 41b and the disk 10.

이와 같은 차량용 디스크 브레이크의 제동 및 제동해제 동작 시 패드플레이트(40a, 40b)는 패드스프링(50)의 슬라이딩부(51) 내에서 이동한다. 이 때, 패드플레이트(40a, 40b)의 설치돌기(42a, 42b)는 패드스프링(50)과 접하는 면에 끝단부가 곡면으로 형성된 다수의 슬라이딩돌기(43)가 슬라이딩 방향으로 길게 마련되어 있다. In the braking and releasing operation of the vehicular disk brake, the pad plates 40a and 40b move in the sliding part 51 of the pad spring 50. At this time, the mounting protrusions 42a and 42b of the pad plates 40a and 40b are provided with a plurality of sliding protrusions 43 having end portions curved in a sliding direction in a surface in contact with the pad spring 50.

따라서, 슬라이딩돌기(43)들의 끝단만이 패드스프링(50)과 접하게 되므로 접촉하는 면적이 대폭 축소되어 패드플레이트(40a, 40b)와 패드스프링(50) 사이에 작용하는 마찰력은 대폭 저감되며, 슬라이딩돌기(43)들이 슬라이딩 방향으로 길게 형성되어 있으므로 패드플레이트(40a, 40b)가 패드스프링(50)의 슬라이딩부(51) 면을 따라 안정적으로 슬라이딩 이동한다. Therefore, since only the ends of the sliding protrusions 43 come into contact with the pad springs 50, the contact area is greatly reduced, and the frictional force acting between the pad plates 40a and 40b and the pad springs 50 is greatly reduced, and the sliding is reduced. Since the protrusions 43 are formed long in the sliding direction, the pad plates 40a and 40b are slidably moved along the sliding part 51 surface of the pad spring 50.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 차량용 디스크 브레이크는 패드플레이트의 설치돌기에 곡면으로 이루어진 다수의 슬라이딩돌기를 마련함으로써, 슬라이딩돌기의 끝단부만이 슬라이딩부에 접촉되게 하면, 패드플레이트와 패드스프링의 접촉면적은 축소되고, 그에 따라 패드플레이트와 패드스프링 사이에 작용하는 마찰력이 감소되어, 패드플레이트가 패드스프링의 슬라이딩부의 면을 따라 원활하게 이동할 수 있게 되는 작용효과가 있다. As described above in detail, the vehicle disc brake according to the present invention provides a plurality of sliding protrusions having curved surfaces on the installation protrusion of the pad plate, so that only the end of the sliding protrusion contacts the sliding portion, the pad plate and the pad. The contact area of the spring is reduced, thereby reducing the frictional force acting between the pad plate and the pad spring, so that the pad plate can move smoothly along the surface of the sliding portion of the pad spring.
