Description

디스크 브레이크의 심{The Shim for Disk Brake}The Shim for Disk Brake

본 발명은 차량용 디스크브레이크에 관한 것으로써 더욱 상세하게는 디스크브레이크의 패드플레이트와 심(shim)의 개선된 연결구조에 관한것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc brake for a vehicle, and more particularly, to an improved connection structure of a pad plate and a shim of a disc brake.

종래 디스크 브레이크는 제동 유압에 의해 진퇴 운동하도록 피스톤이 내장된 캘리퍼 하우징(10)과, 차체에 고정되며 캘리퍼 하우징(10)의 양단이 가이드로드를통해 슬라이딩 가능하게 장착되는 캐리어(미도시)와, 한 쌍의 패드플레이트(30,30′) 사이에 외주연 일부가 삽입되면서 휠과 함께 회전하는 디스크(40)를 구비한다.Conventional disc brakes include a caliper housing (10) with a built-in piston to move forward and backward by braking hydraulic pressure, a carrier (not shown) fixed to the vehicle body, and both ends of the caliper housing (10) being slidably mounted through a guide rod; A portion of the outer circumference is inserted between the pair of pad plates 30 and 30 'and includes a disk 40 that rotates with the wheel.

캘리퍼 하우징(10)은 피스톤(12)이 설치되는 실린더(13)와, 후술하는 아웃터패드플레이트(30′)를 감싸도록 굽어진 핑거부(11)를 갖추고 있어서, 제동 작용 시 한 쌍의 패드플레이트(30,30′)를 디스크 측으로 밀게 된다.The caliper housing 10 has a cylinder 13 on which a piston 12 is installed and a finger portion 11 bent to surround the outer pad plate 30 ', which will be described later, so that a pair of pad plates can be used during braking action. (30,30 ') is pushed to the disc side.

그리고 캐리어는 차체의 너클에 마운팅 볼트를 통해 견실하게 장착되며, 여기에는 내,외측의 패드플레이트(30,30′)가 디스크(40)를 향해 슬라이딩 가능하게 설치된다. 이 패드플레이트는 피스톤과 접하도록 캐리어 안쪽에 배치되는 인너패드플레이트(30)와, 핑거부(11)와 접하도록 캐리어 바깥쪽에 배치되는 아웃터패드플레이트(30′)로 구별된다. 이러한 인너패드플레이트(30)와 아웃터패드플레이트(30′)에는 이들의 외측면을 덮도록 각각 커버심(60)이 설치되어 있다. 이 커버심(60)은 소정의 두께를 갖는 금속판으로 이루어져 있는데, 이것에 의해 제동 마찰열이 캘리퍼 하우징 측으로 전달되는 것이 방지되게 된다.The carrier is firmly mounted to the knuckle of the vehicle body through mounting bolts, and inner and outer pad plates 30 and 30 'are slidably installed toward the disk 40. The pad plate is divided into an inner pad plate 30 disposed inside the carrier so as to contact the piston, and an outer pad plate 30 'disposed outside the carrier so as to contact the finger portion 11. The inner pad plate 30 and the outer pad plate 30 'are provided with cover shims 60 so as to cover their outer surfaces. The cover shim 60 is made of a metal plate having a predetermined thickness, whereby the braking frictional heat is prevented from being transferred to the caliper housing side.

따라서 운전자가 브레이크패달을 밟아 마스터실린더로부터 발생된 제동유압이 실린더에 전달되면, 피스톤(12)과 함께 인너패드플레이트(30)가 전진하며, 동시에 인너패드플레이트(30)의 전면에 결합되어있는 패드(20)가 회전하는 디스크(40)의 일측면에 순간적으로 압착된다. 아울러 실린더(13)에 잔존하는 유압에 의해 캘리퍼 하우징(10)이 피스톤(12)과 반대방향으로 이동하면서 핑거부(11)가 아웃터패드플레이트(30′)를 밀어, 이에 부착된 패드(20′)가 디스크(40)의 타측면에 압착되어 제동력을 발휘한다. 이러한 제동 작용 시 발생된 마찰열은 대부분 대기 중으로 발산되며, 커버심에 의해 캘리퍼 하우징으로 직접 전달되는 것이 방지된다.Therefore, when the driver presses the brake pedal and the brake hydraulic pressure generated from the master cylinder is transmitted to the cylinder, the inner pad plate 30 moves forward together with the piston 12, and at the same time, the pad coupled to the front surface of the inner pad plate 30. 20 is instantaneously crimped to one side of the rotating disk 40. In addition, while the caliper housing 10 moves in the opposite direction to the piston 12 due to the hydraulic pressure remaining in the cylinder 13, the finger portion 11 pushes the outer pad plate 30 'and the pad 20' attached thereto. ) Is pressed against the other side of the disk 40 to exert a braking force. Most of the frictional heat generated during this braking action is dissipated into the atmosphere and is prevented from being transferred directly to the caliper housing by the cover shim.

그리고 브레이크패달에서 발을 떼면, 실린더에 작용하던 제동유압이 해제되며, 디스크와 패드의 잔류 마찰력(잔류 드래그, Residual Drag)에 의해 패드플레이트(30,30′)와 함께 피스톤(12)이 복원되면서 다시 디스크(40)와 패드(20,20′)가 떨어진다.When the foot is released from the brake pedal, the braking hydraulic pressure acting on the cylinder is released, and the piston 12 is restored along with the pad plates 30 and 30 'by the residual friction of the disk and the pad (residual drag). The disk 40 and the pads 20 and 20 'fall again.

이러한 종래 디스크 브레이크에서는 도1에 도시되어 있듯이 커버심(2)과 패드플레이트(1)가 연결됨에 있어서, 커버심(2)에 절곡된 연장부(4)를 두어 접착제를 사용하여 연장부를 플레이트에 접착하거나 패드플레이트(1)에 홈을 만들고 클립으로 고정하는등의 방법을 이용하였다. 그러나 이러한 방식의 연결구조는 접촉면적이 좁고 또한 한 쌍의 패드플레이트(1)가 슬라이딩 가능하도록 캐리어에 헐겁게 장착되어 있기 때문에, 커버심(2)이 밀리게 되고 이들이 복원되는 과정에서 상당한 소음이 발생되는 문제점이 있다. 즉 제동 작용이 해제되면서 인너패드플레이트와 아웃터패드플레이트는 캐리어 단부와 부딪치며, 시끄럽게 덜컥거리는 떨림 현상에 의해 레틀 노이즈(rattle noise)가 발생된다.In the conventional disc brake, as shown in FIG. 1, when the cover shim 2 and the pad plate 1 are connected, the extension 4 is bent on the cover shim 2 and the extension is attached to the plate using an adhesive. A method of bonding or making a groove in the pad plate 1 and fixing it with a clip was used. However, this connection structure has a narrow contact area and is loosely mounted on the carrier so that the pair of pad plates 1 can slide, so that the cover shim 2 is pushed back and considerable noise is generated in the process of restoring them. There is a problem. That is, as the braking action is released, the inner pad plate and the outer pad plate collide with the carrier end, and rattle noise is generated by a noisy trembling phenomenon.

본 발명은 이와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 커버심과 패드플레이트의 연결구조를 개선하여 확고하게 커버심을 패드플레이트에 고정시킴으로써 레틀 노이즈 발생원인을 효과적으로 제거할 수 있는 디스크 브레이크를 제공하는 것이다.The present invention is to solve such a problem, an object of the present invention is to improve the connection structure of the cover shim and the pad plate to firmly secure the cover shim to the pad plate by disc brake which can effectively eliminate the cause of the noise noise To provide.

Carrier, caliper mounted on both sides of the carrier and arranged to cover the outer surface of the inner and outer pad plate to prevent braking frictional heat from being transferred to the caliper housing side to operate the inner and outer pad plates. In the disc brake with cover shim,

상기 커버심은 중간 소정부위 패드플레이트측으로 절곡된 제1절곡부와 반대편으로 절곡된 제2절곡부를 복수개 가지고 있으며,The cover shim has a plurality of second bent portions bent to the opposite side of the first bent portion bent toward the pad portion of the middle predetermined portion,

이하, 본 발명에 따른 하나의 바람직한 실시 예를 첨부도면을 참조하여 상세히 설명한다. 도에서 보듯이, 본 실시예에 따른 디스크 브레이크의 커버심(60)은 회전하는 디스크(40)와 피스톤(12)과 같은 가압부재에 의해 디스크(40)에 대해 전진하여 밀착 가능하게 설치된 브레이크 패드(20) 사이에서 발생되는 소음을방지하기 위한 것으로서, 패드플레이트의 실린더측 외면에 밀착 고정된다. 본 실시예에 의한 구성은 ,Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings. As shown in the figure, the cover shim 60 of the disc brake according to the present embodiment is a brake pad provided to be in close contact with the disc 40 by a pressing member such as a rotating disc 40 and a piston 12. It is to prevent the noise generated between the (20), it is fixed close to the cylinder-side outer surface of the pad plate. The configuration according to the present embodiment,

휠과 함께 회전하는 디스크(40), 디스크(40)와 마찰하도록 내면에 패드(20,20′)가 부착되며 양측 단부에 돌출부가 마련된 인너패드플레이트(30)와 아웃터패드플레이트(30′), 돌출부가 미끄럼 가능하게 배치되도록 양측 단부에 슬라이딩 채널이 마련되며 차체에 고정되는 캐리어(미도시), 캐리어의 양측에 진퇴운동 가능하게 장착되며 인너 · 아웃터패드플레이트(30,30′)를 작동시키기 위해 피스톤이 내장된 캘리퍼 하우징(10)과, 캘리퍼 하우징(10) 측으로 제동 마찰열이 전달되지 않도록 인너 · 아웃터패드플레이트의 외면을 덮도록 배치된 커버심(60)을 갖춘 디스크 브레이크를 구비한다.Inner pad plate 30 and outer pad plate 30 'having pads 20 and 20' attached to the inner surface of the disk 40 rotating together with the wheels and the disk 40 and having protrusions at both ends thereof. Sliding channels are provided at both ends so that the protrusions are slidably arranged, and carriers (not shown) fixed to the vehicle body are mounted on both sides of the carrier so as to move forward and backward and to operate the inner and outer pad plates 30 and 30 '. A disc brake having a caliper housing 10 having a built-in piston and a cover shim 60 disposed to cover the outer surface of the inner and outer pad plates so that braking frictional heat is not transmitted to the caliper housing 10 side.

이때 상기 인너 · 아웃터패드플레이트(30,30′)의 외면에는 원형의 돌기부(31)를 소정부위에 복수개 마련한다.At this time, on the outer surface of the inner outer pad plates (30, 30 '), a plurality of circular protrusions (31) are provided at predetermined portions.

또한 상기 인너 · 아웃터패드플레이트(30,30′) 외면에는 원형의 둘레홈부(32)를 소정부위에 복수개 마련한다.In addition, a plurality of circular circumferential grooves 32 are provided at predetermined portions on outer surfaces of the inner and outer pad plates 30 and 30 '.

또한 상기 커버심(60)에는 패드플레이트(30)와 결합되는 결합면 부위로 절곡되고 중공의 제1절곡부(61)를 마련하여 상기 원형의 둘레홈부(32)에 삽입되도록 한다.In addition, the cover shim 60 is bent to the coupling surface portion coupled to the pad plate 30 to provide a hollow first bent portion 61 to be inserted into the circular circumferential groove 32.

또한 상기 커버심(60)에는 상기 제1절곡부(61)와 반대방향으로 절곡되고 중공의 제2절곡부(62)를 마련하여 상기 원형의 돌기부(31)에 지지되도록 한다.In addition, the cover shim 60 is bent in the opposite direction to the first bent portion 61 and provided with a hollow second bent portion 62 to be supported by the circular protrusion 31.

상기 제1절곡부(61)와 제2절곡부(62)는 펀칭과 같은 프레스가공으로 형성된다. 중심부에 강하게 프레싱을 하여 둘레로 절곡부를 형성하면서 가운데는 천공되도록 하는것이다.The first bent portion 61 and the second bent portion 62 are formed by press working such as punching. Pressing strongly in the center forms a bend around the periphery of the center.

이렇게 제1절곡부(61)와 제2절곡부(62)가 각각 패드플레이트(30)의 둘레홈부(32)와 돌기부(31)에 삽입되고 지지되며 절곡부를 제외한 모든면적이 접착면적이 되므로 제동시에 커버심(60)의 떨림방지와 견고한 부착에 효과적이게 된다. 이하에서는 본 발명의 실시예에 의한 작용과 효과에 대해서 알아본다.Thus, the first bent portion 61 and the second bent portion 62 are inserted and supported in the circumferential groove portion 32 and the protrusion portion 31 of the pad plate 30, respectively. At the same time, the cover shim 60 is effectively prevented from shaking and firmly attached. Hereinafter, the operation and effects of the embodiments of the present invention will be described.

먼저, 자동차가 주행하고 있는 상태에서 운전자가 브레이크패달(미도시)을 밟으면, 마스터실린더(미도시)에서 제동유압이 형성되고 이것은 휠실린더(13)로 전달되어 피스톤(12)이 전진한다.First, when the driver steps on the brake pedal (not shown) while the vehicle is running, a braking hydraulic pressure is formed in the master cylinder (not shown), which is transmitted to the wheel cylinder 13 and the piston 12 is advanced.

이에 따라 캐리어에 설치된 인너패드플레이트(30)가 전진하면서 회전하는 디스크(40) 측면에 패드(20)가 마찰하여 제동력이 발생된다. 아울러 실린더에 잔존하는 유압에 의해 캘리퍼 하우징(10)은 피스톤(12)과 반대방향으로 이동하며, 이것에 의해 핑거부(11)가 아웃터패드플레이트(30′)를 끌어 당겨 이의 패드(20′)가 디스크(40) 측면에 압착 제동력이 발생된다.Accordingly, the pad 20 rubs against the side of the disk 40 rotating as the inner pad plate 30 installed in the carrier moves forward to generate a braking force. In addition, the caliper housing 10 moves in the opposite direction to the piston 12 due to the hydraulic pressure remaining in the cylinder, whereby the finger portion 11 pulls the outer pad plate 30 'to its pad 20'. A pressing braking force is generated on the side of the disk 40.

이러한 제동 작용 시 커버심(60)에 의해 패드(20,20′)와 디스크(40)와의 마찰로 발생된 열이 피스톤(40)과 핑거부(11)측으로 전달되는 것이 방지된다. 즉, 커버심(60)에 의해 제동 마찰열이 캘리퍼 하우징(10)측으로 전달되지 않고 대부분이 대기 중으로 발산된다.In this braking operation, heat generated by friction between the pads 20 and 20 'and the disk 40 is prevented from being transferred to the piston 40 and the finger portion 11 by the cover shim 60. That is, the braking frictional heat is not transmitted to the caliper housing 10 side by the cover shim 60 and most of the heat is dissipated to the atmosphere.

그리고 운전자가 브레이크패달을 놓아 제동유압이 해제되면, 각 패드(20,20′)는 휠과 함께 회전하는 디스크와 마찰하면서 다시 이격됨과 동시에 피스톤 역시 실린더로 복원된다.When the brake hydraulic pressure is released by the driver by releasing the brake pedal, each of the pads 20 and 20 'rubs against the disk rotating with the wheel and is spaced apart again and the piston is also restored to the cylinder.

이 때, 각 패드플레이트의 둘레홈부와 돌기부에는 커버심(60)의 제1절곡부(61)와 제2절곡부(62)가 각각 삽입되고 지지되며 그 외 전 부분에 접착제가 도포되므로 상기 커버심(60)은 매우 견고하게 상기 패드플레이트(30,30′)에 접착상태를 유지하게된다. 따라서 제동시 커버심(60)이 한쪽으로 쏠리는 현상도 없어지며 제동 작용 해제 시 레틀 노이즈 발생이 방지된다.At this time, the first bent portion 61 and the second bent portion 62 of the cover shim 60 are inserted and supported in the circumferential groove portion and the protrusion portion of each pad plate. The shim 60 is very firmly attached to the pad plates 30 and 30 '. Therefore, the phenomenon that the cover shim 60 is pulled to one side during braking is also eliminated, and when the braking action is released, the lettle noise is prevented.

이에 따라 제동 작용 해제 시 디스크와 패드의 잔류 드레그(Residual Drag)가 개선됨과 동시에 각 패드플레이트의 떨림 현상이 방지됨으로써, 전반적인 디스크 브레이크의 작동소음이 월등하게 저감된다.Accordingly, when the braking action is released, residual drag of the disc and the pad is improved, and the shaking of each pad plate is prevented, thereby reducing the overall operation noise of the disc brake.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 디스크 브레이크에 의하면, 제동 마찰열이 캘리퍼 하우징으로 전달되는 것을 방지하기 위한 커버심과 패드플레이트를 연결부재를 이용하여 밀착고정시키는 구성으로 되어 있다. 이에 따라 제동 마찰열이 캘리퍼 하우징으로 전달되는 것이 방지됨은 물론이며, 제동시에 캐리어가 변형될 경우에도 커버심이 전단력에 의하여 패드플레이트에서 이탈되는경우를 방지하며, 레틀 노이즈를 효과적으로 방지할 수 있는 작용효과가 있다.As described in detail above, according to the disc brake according to the present invention, the cover shim and the pad plate for preventing the braking friction heat from being transferred to the caliper housing are fixed by using the connecting member. As a result, the braking friction heat is prevented from being transferred to the caliper housing, and even when the carrier is deformed during braking, the cover core is prevented from being separated from the pad plate by the shear force, and the effect of effectively preventing the lettle noise have.
