Description

제동성능이 향상된 디스크 브레이크Disc brakes with improved braking performance

본 고안은 제동성능이 향상된 디스크 브레이크에 관한 것으로, 특히 제동시 패드와 마찰되는 디스크의 유효마찰면적을 넓게 연장시켜 제동성능을 배가시킬 수 있도록 된 제동성능이 향상된 디스크 브레이크에 관한 것이다.The present invention relates to a disk brake with improved braking performance, and more particularly, to a disk brake with improved braking performance that can double the braking performance by extending the effective frictional area of the disk friction with the pad during braking.

일반적으로 차량에는 주행중 필요에 따라 차속을 선택적으로 감속시키거나 정지시켜 차량을 정차상태로 하는 제동장치를 구비하고 있는 바, 이러한 제동장치는 크게 기계식과 유압식으로 구분되는데, 유압식의 제동장치는 운전자의 조작력을 링크나 유압을 이용하여 증대시킨 상태로 전달하는 조작기구와, 이 조작기구의 힘을 받아 유압을 발생시키는 유압발생기구 및, 이 유압발생기구로부터 발생된 유압을 전달받아 차륜에 제동력을 발생시키는 제동기구로 구성된다.In general, a vehicle is provided with a braking device for selectively decelerating or stopping the vehicle speed to stop the vehicle as needed while driving. Such a braking device is classified into a mechanical and a hydraulic type. An operating mechanism that transmits the operating force in a state in which the operating force is increased by using a link or hydraulic pressure, a hydraulic generating mechanism that generates hydraulic pressure by the force of the operating mechanism, and generates a braking force on the wheel by receiving the hydraulic pressure generated from the hydraulic generating mechanism. It consists of a brake mechanism.

한편 상기와 같은 유압식의 제동장치에서 디스크 브레이크는 회전하는 디스크에 패드를 밀착시켜 제동력을 발생시키는 제동장치인 바, 이 디스크 브레이크는 도 1에 도시된 바와 같이, 휠허브와 함께 회전하는 디스크(11)와, 이 디스크(11)의 양측에 밀착되어 마찰력을 발생시키는 패드(12) 및, 이 패드(12)를 배면에서 지지하고 있는 백플레이트(13)를 디스크(11)쪽으로 밀도록 유압을 받는 피스톤(14), 그리고 이 피스톤(14)을 내장한 캘리퍼(15)로 구성되어 있다.Meanwhile, in the hydraulic braking device as described above, the disc brake is a braking device that generates a braking force by bringing a pad into close contact with the rotating disk. The disk brake rotates together with the wheel hub as shown in FIG. 1. ), A pad 12 in close contact with both sides of the disk 11 and generating a frictional force, and a back plate 13 supporting the pad 12 from the rear thereof to receive hydraulic pressure to push the disk 11 toward the disk 11. It consists of the piston 14 and the caliper 15 in which the piston 14 was built.

따라서, 상기와 같이 구성된 디스크 브레이크는, 제동시 상기 피스톤(14)이 제동압유에 의해 가압받게 되면, 이 피스톤(14)은 밀려 백플레이트(13)를 밀게 되고, 이에 따라 백플레이트(13)는 패드(12)를 디스크(11)쪽으로 밀어 이 디스크(11)의 양쪽 외주면에 패드(12)가 닿게 하여 디스크(11)를 가압하게 함으로써 휠허브와 함께 회전하는 디스크(11)의 회전이 저지되어 제동이 이루어지게 된다.Therefore, in the above-described disc brake, when the piston 14 is pressurized by the braking pressure oil during braking, the piston 14 is pushed to push the back plate 13, and thus the back plate 13 is By pushing the pad 12 toward the disk 11, the pads 12 are brought into contact with both outer peripheral surfaces of the disk 11 to press the disk 11, thereby preventing rotation of the disk 11 that rotates with the wheel hub. Braking is achieved.

그러나, 상기와 같은 디스크 브레이크식의 제동장치에서는, 제동시 발생되는 제동력이 전적으로 디스크(11)의 양쪽 외주면에 가압되어 마찰되는 패드(12)와 디스크(11)사이의 접촉면적과 이에 가해지는 압력에 의해 결정되므로 동일한 형상을 유지하고서도 제동성능을 향상시키는 데에는 그 한계가 있는 단점이 있었다.However, in the disc brake type braking device as described above, the contact area between the pad 12 and the disc 11 and the pressure applied thereto, the braking force generated during braking is entirely pressurized on both outer peripheral surfaces of the disc 11. Since it is determined by, there is a drawback that there is a limit in improving braking performance while maintaining the same shape.

이에 본 고안은 상기와 같은 단점을 해소하기 위해 안출된 것으로, 제동시 디스크와 이에 맞닿는 패드의 접촉면적을 확장시켜 넓혀 주도록 되어 동일한 외형에서 더 나은 제동성능을 얻도록 하여 제동효과를 배가시킬 수 있도록 된 제동성능이 향상된 디스크 브레이크를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above disadvantages, and when braking, the contact area between the disk and the pad contacting the disk is expanded to widen to obtain a better braking performance in the same shape so as to double the braking effect. The object is to provide a disc brake with improved braking performance.

상기한 바의 목적을 달성하기 위한 본 고안은, 휠허브와 함께 회전하는 디스크와, 이 디스크의 양측에 밀착되어 마찰력을 발생시키는 패드, 이 패드를 배면에서 지지하는 백플레이트 및, 제동시 이 백플레이트를 가압하여 디스크쪽으로 밀도록 유압을 받는 피스톤, 그리고 이 피스톤을 내장한 캘리퍼로 구성된 자동차의 디스크 브레이크장치에 있어서, 상기 디스크의 가장자리부위에는 동심원상으로 복수개로 오목하게 파이도록 형성된 요홈부가 마련되고, 이 디스크의 요홈부에 대응되는 패드의 전면에는 볼록하게 돌출된 형태의 돌기부가 역시 복수개로 마련되어 제동시 디스크의 요홈부내로 패드의 돌기부가 삽입되도록 구성된 것을 특징으로 한다.The present invention for achieving the above object is a disk that rotates with the wheel hub, a pad in close contact with both sides of the disk to generate a friction force, a back plate supporting the pad on the back, and the back during braking In a disc brake device of an automobile comprising a piston pressurized to press a plate and pushed toward a disc, and a caliper incorporating the piston, the disc edge portion of the disc is provided with a concave groove formed to concave a plurality of concentrically. On the front surface of the pad corresponding to the recess of the disk, a plurality of protrusions having convex protrusions are also provided, so that the protrusion of the pad is inserted into the recess of the disk during braking.

이하, 본 고안의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 고안에 따른 제동성능이 향상된 디스크 브레이크의 캘리퍼부위를 도시한 부분단면도이다.Figure 2 is a partial cross-sectional view showing a caliper portion of the disk brake with improved braking performance according to the present invention.

본 고안에 따른 제동성능이 향상된 디스크 브레이크는 도면에 도시된 바와 같이, 휠허브와 함께 회전하는 디스크(1)와, 이 디스크(1)의 양측에 밀착되어 마찰력을 발생시키는 패드(2), 이 패드(2)를 배면에서 지지하는 백플레이트(3) 및, 제동시 이 백플레이트(3)를 가압하여 디스크(1)쪽으로 밀도록 유압을 받는 피스톤(4), 그리고 이 피스톤(4)을 내장한 캘리퍼(5)로 구성된 자동차의 디스크 브레이크장치에 있어서, 상기 디스크(1)의 가장자리부위에는 동심원상으로 오목하게 파일 형태의 요홈부(6)가 복수개로 형성되고, 이 디스크(1)의 요홈부(6)에 대응되는 패드(2)의 전면에는 볼록하게 돌출된 형태의 돌기부(7)가 역시 복수개로 형성되어 있는 구조로 되어 있다.As shown in the drawing, a disk brake having improved braking performance according to the present invention includes a disk 1 rotating together with a wheel hub, and a pad 2 in close contact with both sides of the disk 1 to generate frictional force. The back plate (3) supporting the pad (2) from the back, a piston (4) receiving hydraulic pressure to press the back plate (3) to the disk (1) during braking, and this piston (4) built-in In the disc brake device of an automobile composed of one caliper (5), a plurality of groove-shaped groove portions (6) are formed in a concave concave shape at the edge portion of the disc (1), and the yaw of the disc (1) The front surface of the pad 2 corresponding to the groove 6 has a structure in which a plurality of protrusions 7 are formed.

여기서 제동시 상기 피스톤(4)이 백플레이트(3)를 디스크(1)를 향해 가압하게 되면, 상기 디스크(1)의 양쪽 가장자리부위에 동심원상으로 오목하게 파인 형태의 요홈부(6)는 백플레이트(3)와 일체로 이동되는 패드(2)의 전면에 형성된 돌기부(7)내로 삽입되면서 패드(2)로부터 마찰력을 전달받아 제동이 이루어지게 되는데, 이 경우 상기 디스크(1)와 패드(2) 사이의 접촉면적이 종래보다 넓게 연장되게 된다.Here, when the piston 4 presses the back plate 3 toward the disk 1 during braking, the groove 6 having a concave concave shape is formed on both edges of the disk 1. Inserted into the projection 7 formed on the front surface of the pad (2) which is integrally moved with the plate (3) is braking is made by receiving a friction force from the pad (2), in this case the disk (1) and the pad (2) The area of contact between the two ends is wider than in the prior art.

따라서 상기와 같이 디스크(1)의 가장자리부위에 동심원상으로 오목하게 파인 형태의 요홈부(6)와 패드(2)의 전면에 형성된 돌기부(7)는, 제동시 디스크(1)와 패드(2) 사이의 접촉면적을 넓게 연장시켜 주도록 되어 제동성능이 보다 더 향상될 수 있도록 해 준다.Therefore, as described above, the recess 6 formed in the concave concave shape at the edge of the disk 1 and the projection 7 formed on the front surface of the pad 2 are the disc 1 and the pad 2 during braking. The contact area between the wheels is extended to a wide range, so that the braking performance can be further improved.

이상 설명한 바와 같이 본 고안에 따른 제동성능이 향상된 디스크 브레이크에 의하면, 제동시 디스크와 접촉되는 패드가 종래보다 더 넓은 면적으로 접촉될 수 있게 구성됨으로써, 동일한 외형에서 더 나은 제동효과를 기대할 수 있는 이점이 있게 된다.As described above, according to the disk brake having improved braking performance according to the present invention, the pad that comes into contact with the disk during braking is configured to be in contact with a larger area than before, so that a better braking effect can be expected in the same appearance. This will be.
