본 발명은 캘리퍼 어셈블리의 브레이크패드와 커버심 결합구조에 관한 것으 로서, 보다 상세하게는 플로팅 타입 캘리퍼를 사용하는 캘리퍼 어셈블리에서 피스톤과 접촉되도록 패드에 설치된 커버심의 결합력을 향상시키고 소음 발생을 감소시킬 수 있는 캘리퍼 어셈블리의 브레이크패드와 커버심 결합구조에 관한 것이다.The present invention relates to a brake pad and cover shim coupling structure of the caliper assembly, and more particularly, to improve the coupling force of the cover shim installed in the pad to contact the piston in the caliper assembly using a floating type caliper and to reduce noise generation. The brake pad and cover shim coupling structure of the caliper assembly.

일반적으로, 자동차의 브레이크에는 디스크 브레이크 장치가 많이 적용되는 바, 상기한 디스크 브레이크 장치에는 캘리퍼 어셈블리가 설치되어 있다.In general, a disc brake device is widely applied to a brake of an automobile, and the disc brake device is provided with a caliper assembly.

상기한 캘리퍼 어셈블리는 브레이크 패드가 내재됨과 아울러 너클에 고정되는 캐리어와, 상기한 캐리어에 가이드로드 및 가이드공으로 결합되어 이동 자재하고 피스톤이 설치된 캘리퍼로 구성되어 있는 바, 상기한 피스톤은 브레이크 유압에 의해 작동하게 구성되어 있을 뿐만 아니라 패드를 가압하도록 설치된다.The caliper assembly is composed of a carrier which has a brake pad inherent and is fixed to a knuckle, and a caliper having a piston installed in the carrier by being coupled to the carrier by a guide rod and a guide hole. It is not only configured to operate but also to pressurize the pad.

상기한 바와 같은 캘리퍼 어셈블리에서 캘리퍼와 브레이크 패드의 결합 상태는 도2에 도시된 바와 같이 캘리퍼 하우징(50)의 실린더(51)에 설치된 피스톤(52)과, 상기한 캘리퍼 하우징(50)의 핑거부(53)에 개재된 상태에서 피스톤(52)에 의해 가압되도록 설치됨과 아울러 가운데 브레이크 디스크(D)가 위치되는 브레이크 패드(54)와, 상기한 브레이크 패드(54)에 설치되어 피스톤(52)의 가압 시 접촉되도록 설치된 커버심(55)으로 이루어져 있다.In the caliper assembly as described above, the caliper and the brake pad are coupled to each other by the piston 52 installed in the cylinder 51 of the caliper housing 50 and the finger part of the caliper housing 50 as shown in FIG. 2. The brake pad 54 is installed so as to be pressurized by the piston 52 in the state interposed in the 53 and the brake pad D in which the brake disc D is located, and the brake pad 54 is installed to the brake pad 54. It consists of a cover shim 55 installed to be in contact when pressed.

상기한 피스톤(52)과 직접 접촉되도록 패드(54)에 커버심(55)이 결합되어 있는 바, 상기한 커버심(55)에는 다수의 클립(56)이 연장 형성되어 패드(54)에 끼워지면서 고정된다.The cover shim 55 is coupled to the pad 54 so as to be in direct contact with the piston 52. A plurality of clips 56 are formed on the cover shim 55 to be inserted into the pad 54. Built and fixed.

즉, 도3에 도시된 바와 같이 커버심(55)에 형성된 클립(56)의 종단이 패드(54)에 끼워지면서 소정 탄성으로 가압 및 결합됨으로써, 커버심(55)이 패드(54) 에 안정적으로 결합되도록 구성된 것이다.That is, as shown in FIG. 3, the end of the clip 56 formed on the cover shim 55 is pressed and coupled with a predetermined elasticity while being fitted to the pad 54, whereby the cover shim 55 is stable to the pad 54. It is configured to be combined.

특히, 상기한 패드(54)에는 피스톤(52)과 커버심(55)의 접촉 시 커버심(55)과 패드(54)의 간섭을 방지하기 위해 코이닝(COINING) 가공으로 경사부(57)가 형성되어 있다.In particular, the pad 54 has an inclined portion 57 by a coining process to prevent interference between the cover shim 55 and the pad 54 when the piston 52 and the cover shim 55 are in contact with each other. Is formed.

그러나, 상기한 바와 같이 커버심을 패드에 결합시키기 위해 커버심에 결합부를 형성하고 상기한 결합부가 패드의 백플레이트 모서리 부분을 가압하면서 결합하도록 하면, 상기한 결합부와 패드가 점접촉하게 됨으로써 결합력이 낮아 피스톤의 가압 시 커버심이 유동하면서 소음을 발생시키는 문제점이 있다.However, if the coupling portion is formed on the cover core to couple the cover core to the pad as described above, and the coupling portion is pressed while pressing the edge portion of the back plate of the pad, the coupling portion and the pad are brought into point contact so that the bonding force is increased. When the pressure of the piston is low, there is a problem of generating noise while the cover shim flows.

또한, 커버심과 패드이 간섭을 방지하기 위해 패드에 별도의 공정인 코이닝 공정을 통해 경사부를 형성하여야 하기 때문에, 제작 공정이 복잡하게 되는 문제점이 있다.In addition, since the cover seam and the pad should be inclined through a coining process which is a separate process on the pad to prevent interference, the manufacturing process is complicated.

따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 패드를 제작할 때 코이닝 공정을 통해 경사부를 형성하지 않아도 패드와 커버심의 간섭을 방지할 수 있고, 패드와 커버심의 결합력을 향상시켜 소음 발생을 개선한 캘리퍼 어셈블리의 브레이크패드와 커버심 결합구조를 제공함에 있다.Accordingly, an object of the present invention is to solve the above problems, it is possible to prevent the interference between the pad and the cover seam without forming the inclined portion through the coining process when manufacturing the pad, improve the coupling force between the pad and the cover seam noise The present invention provides a brake pad and cover shim coupling structure of the caliper assembly which has improved generation.

상기한 목적을 실현하기 위하여 본 발명은, 피스톤에 의해 가압되는 브레이크 패드와 결합되는 커버심에 다수 형성됨과 아울러 패드에 결합되었을 때 면접촉하도록 접촉면이 형성되고 패드의 모서리 부분과 커버심의 간섭되지 않도록 곡선부가 형성된 클립으로 구성함을 특징으로 한다.In order to realize the above object, the present invention is formed in a plurality of cover shims coupled to the brake pads pressed by the piston, and the contact surface is formed so as to be in surface contact when coupled to the pad, and so as not to interfere with the edge of the pad and the cover shim. It is characterized by consisting of a clip formed a curved portion.

도1은 본 발명에 따른 캘리퍼 어셈블리의 브레이크패드와 커버심 결합구조를 도시한 확대 단면도로서, 모서리 부분에 코이닝 가공되지 않은 상태인 패드(1)와, 상기한 패드(1)에 결합되는 커버심(55)에 다수 형성됨과 아울러 패드(1)에 결합되었을 때 면접촉하도록 접촉면(2)이 형성되고 패드(1)의 모서리 부분과 커버심(55)의 간섭되지 않도록 곡선부(3)가 형성된 클립(4)으로 이루어져 있다.Figure 1 is an enlarged cross-sectional view showing the structure of the brake pad and the cover core coupling of the caliper assembly according to the present invention, the pad (1) is not coined in the corner portion and the cover is coupled to the pad (1) A plurality of shims 55 are formed and a contact surface 2 is formed to be in surface contact when coupled to the pad 1, and the curved portion 3 is formed so that the edge portion of the pad 1 does not interfere with the cover shim 55. It consists of a formed clip (4).

즉, 상기한 커버심(55)을 패드(1)에 결합시키게 되면, 상기한 곡선부(3)는 충분히 길게 형성되어 있기 때문에 패드(1)와 간섭되지 않게 되고, 접촉면(2)은 넓은 면적으로 패드(1)와 결합됨으로써, 결합력을 향상시키도록 하는 것이다.That is, when the cover shim 55 is coupled to the pad 1, the curved portion 3 is formed long enough so that it does not interfere with the pad 1, and the contact surface 2 has a large area. By being combined with the pad 1, to improve the bonding force.

또한, 상기한 클립(4)의 접촉면(2)이 패드(1)와 결합되었을 때 클립(4)이 빠지지 않도록 패드(1)에 걸림턱(5)이 형성되어 있다.In addition, when the contact surface 2 of the clip 4 is engaged with the pad 1, the locking jaw 5 is formed on the pad 1 so that the clip 4 does not fall out.

상기한 패드(1)에 코이닝 가공을 통해 종래와 같은 경사부(57)를 형성하지 않아도 됨으로써, 패드 가공 공정이 단순화되어 작업 효율이 대폭 향상될 수 있다.Since the inclined portion 57 does not need to be formed on the pad 1 through coining, the pad processing process can be simplified and the work efficiency can be greatly improved.

상기한 바와 같은 본 발명의 작용 효과를 설명하면 패드(1)에 커버심(55)을 결합시키기 위해서는 패드(1)의 일측면(피스톤과 접촉되는 부분)에 커버심(55)을 위치시키고, 커버심(55)의 클립(4)을 패드(1)에 끼우게 된다.In describing the operation and effect of the present invention as described above, in order to couple the cover shim 55 to the pad 1, the cover shim 55 is positioned on one side (part in contact with the piston) of the pad 1, The clip 4 of the cover shim 55 is fitted to the pad 1.

클립(4)이 패드(1)에 끼워지게 되면 패드(1)의 걸림턱(5)에 의해 클립(4)이 배면 방향으로는 쉽게 빠지지 않는 상태가 되는 바, 이 상태에서 곡선부(3)는 패드(1)와는 비교적 멀리 이격된 상태로서 패드(1)와 커버심(55)이 서로 간섭되지 않는 상태가 된다.When the clip 4 is inserted into the pad 1, the clip 4 is not easily pulled out in the back direction by the locking jaw 5 of the pad 1. In this state, the curved portion 3 Is a state in which the pad 1 and the cover shim 55 do not interfere with each other relatively relatively apart from the pad 1.

상기한 바와 같이 커버심(55)이 결합된 캘리퍼 어셈블리가 차량에 장착되어 사용되면, 브레이크의 작동 시 피스톤(52)이 유압에 의해 작동하면서 커버심(55)을 가압하게 된다.As described above, when the caliper assembly coupled with the cover shim 55 is mounted and used in the vehicle, the piston 52 pressurizes the cover shim 55 while being operated by hydraulic pressure when the brake is operated.

이때, 상기한 커버심(55)이 매우 큰 압력으로 가압됨과 아울러 패드(1)가 브레이크 디스크에 의해 회전력을 받아 일정량 회전 유동하게 되지만, 상기한 커버심(55)이 패드(1)에 견고하게 결합되어 있기 때문에, 커버심(55)과 패드(1)와의 사이에서 소음이 발생되지 않게 된다.At this time, while the cover shim 55 is pressurized to a very large pressure and the pad 1 is rotated by a predetermined amount under rotational force by the brake disc, the cover shim 55 is firmly attached to the pad 1. Since it is coupled, the noise is not generated between the cover shim 55 and the pad 1.

즉, 커버심(55)의 클립(4)이 패드(1)에 면접촉되어 있기 때문에 종래에 비해 매우 큰 결합력을 갖게 됨으로써, 패드(1)와 커버심(55)과의 유동에 의한 소음 발생을 감소시킬 수 있는 것이다.That is, since the clip 4 of the cover shim 55 is in surface contact with the pad 1, it has a much larger bonding force than in the related art, thereby generating noise due to the flow between the pad 1 and the cover shim 55. Can be reduced.

물론, 상기한 커버심(55)이 패드(1)와 분리되려는 힘을 받게 되어도 상기한 걸림턱(5)이 커버심(55)을 지지하고 있기 때문에, 커버심(55)이 쉽게 분리되지는 않게 된다.Of course, even if the cover shim 55 is subjected to the force to be separated from the pad 1, because the locking jaw 5 supports the cover shim 55, the cover shim 55 is not easily separated. Will not.

이상과 같이 본 발명은 브레이크 패드와 커버심을 결합시킬 때 커버심에서 연장된 클립과 패드가 면접촉하도록 형성함과 아울러 패드와 간섭되지 않도록 곡선부를 형성함으로써, 패드 가공 공정중 코이닝 공정을 삭제하여 패드 제작 효율을 향상시킬 수 있고, 커버심과 패드의 결합력을 향상시켜 소음 감소을 이룰 수 있는 잇점이 있는 것이다.As described above, the present invention eliminates the coining process of the pad processing process by forming a curved portion so as not to interfere with the pad and to form a clip and the pad extended from the cover core when the brake pad and the cover shim are engaged. The pad manufacturing efficiency can be improved, and the coupling force between the cover seam and the pad can be improved to achieve noise reduction.
