본 발명은 자동차의 디스크 브레이크 열분산장치에 관한 것으로, 더욱 상세하게는 제동시 클리퍼의 패드가 디스크를 밀어붙여 마찰열로 인해 디스크의 변형이 발생되는 것을 방지할 수 있도록 디스크의 내주면에 엠보싱부를 형성하여 열분산이 원활히 이루어지도록 한 자동차의 디스크 브레이크 열분산장치에 관한 것이다.The present invention relates to a disc brake heat dissipation device of an automobile, and more particularly, by forming an embossed portion on an inner circumferential surface of a disc so that the pad of the clipper pushes the disc during braking to prevent deformation of the disc due to frictional heat. Disclosed is a disc brake heat dissipation device for an automobile, which facilitates heat dissipation.
일반적으로 발 브레이크는 바퀴의 안쪽에 장치되어 있는 브레이크 드럼 또는 브레이크 디스크 등에 마찰재를 밀어붙여 그 마찰력을 이용하여 제동력을 발생시키는 것으로 운전자가 브레이크 페달을 밟음으로써 모든 바퀴에 제동력이 발생하도록 되어 있는 것이다.In general, a foot brake pushes a friction material to a brake drum or a brake disc installed inside the wheel to generate a braking force by using the friction force, and the driver brakes the brake pedal to generate braking force on all the wheels.
특히 자동차의 고속화에 따른 드럼식보다 성능이 뛰어난 디스크 브레이크가 많이 사용되는 추세이며, 디스크 브레이크는 예시도면 제1도에 도시한 바와 같이, 바퀴와 함께 회전하는 브레이크 디스크(50)로 양쪽에서 제동패드(52)를 유압에 의해 밀어 붙여 제동하도록 되어 있으며 이와 같은 형식을 캘리퍼형이라고 한다.In particular, disc brakes having better performance than the drum type according to the speed of automobiles are used. Disc brakes are brake discs 50 that rotate together with wheels as shown in FIG. 52) to press the brake by hydraulic pressure, and this type is called caliper type.
예시도면 제2도는 디스크 브레이크의 작동원리를 나타낸 도면으로서, 캘리퍼내의 실린더(60)에 유압을 거는 피스톤(62)은 패드(52)를 화살표 방향으로 이동시켜 양쪽에서 디스크(50)를 압착시킨다. 또한 실린더(60)내의 유압을 없애면 피스톤(62)은 피스톤 시일의 탄성변형에 의해 위치로 되돌아가게 한다. 패드(52)가 마모하면 브레이크 페달의 페달 스트로크가 증대하므로 디스크 브레이크에서는 디스크(50)와 패드(52) 틈새를 자동적으로 조정하는 기능으로 피스톤(62)은 패드(52)의 마모분만큼 진행할 수 있도록 피스톤(62)과 피스톤 시일 사이에 미끄럼이 생겨 피스톤(62)이 마모분만큼 송입되며 그 결과로 브레이크 페달을 놓아줌으로서 실린더(60)내의 유압이 없어지면 시일의 변형분만큼 피스톤(62)을 되돌려져서 패드(52)와 디스크(50)의 틈새를 유지하게 된 것이다.Exemplary Drawing 2 is a view showing the operation principle of the disc brake, the piston 62 for applying hydraulic pressure to the cylinder 60 in the caliper moves the pad 52 in the direction of the arrow to compress the disk 50 on both sides. In addition, eliminating the hydraulic pressure in the cylinder 60 causes the piston 62 to return to position due to the elastic deformation of the piston seal. As the pad 52 wears, the pedal stroke of the brake pedal increases, so the disc brake automatically adjusts the clearance between the disc 50 and the pad 52 so that the piston 62 can proceed as much as the wear of the pad 52. A slip is generated between the piston 62 and the piston seal so that the piston 62 is fed by the amount of wear, and as a result, the brake pedal is released, thereby releasing the hydraulic pressure in the cylinder 60, thereby removing the piston 62 by the deformation of the seal. It is returned to maintain the gap between the pad 52 and the disk 50.
예시도면 제3도의 (a),(b)는 종래의 디스크의 측면과 정면을 나타낸 것으로, 휘일의 허브와 결합할 수 있도록 허브결합부가 디스크의 중심부에 형성되어 있으며 디스크의 양쪽면은 평면으로 형성되어 디스크의 바깥쪽에 패드가 위치하고 있다.Exemplary drawings (a) and (b) of FIG. 3 show side and front surfaces of a conventional disk. Hub coupling portions are formed at the center of the disk so as to be coupled to the hub of the wheel, and both sides of the disk are formed in a plane. The pad is located outside the disk.
그런데 이와같은 종래의 캘리퍼형 디스크 브레이크 장치는 패드가 디스크를 밀어붙여 압착하는 과정에서 고온의 열이 발생되어 디스크가 열팽창으로 인해 변형이 발생되며 이는 차가 정지할 때 스티어링이 떨리는 쥬더현상(Judder Effect)이 발생되는 문제가 있었다.However, in the conventional caliper disc brake device, a high temperature heat is generated while the pad pushes the disk and compresses the disk, so that the disk is deformed due to thermal expansion, which causes the judder effect of the steering shaking when the vehicle is stopped. There was a problem that occurred.
본 발명은 이와같은 종래의 쥬더현상을 방지하기 위하여 발명한 것으로, 제동시 캘리퍼의 패드와 디스크가 압착하면서 발생되는 고온의 열을 원활하게 분산시킬 수 있도록 된 자동차의 디스크 열분산장치를 제공하는데 본 발명의 목적이 있다.The present invention has been invented to prevent such a conventional juder phenomenon, to provide a disk heat dissipation device of a vehicle that can smoothly dissipate the high temperature heat generated when the caliper pad and the disk is pressed during braking. There is an object of the invention.
상기와 같은 목적을 달성하기 위한 본 발명은 패드와 디스크가 압착되면서 발생되는 열을 충분히 분산시켜 발산되도록 디스크 내주면에 표면적을 크게 하는 엠보싱부가 구비된 디스크를 설치한 것에 그 특징이 있다.The present invention for achieving the above object is characterized in that the disk is provided with an embossing portion to increase the surface area on the inner peripheral surface of the disk so as to dissipate the heat generated while the pad and the disk is compressed sufficiently.
이하 본 고안에 따른 자동차의 디스크 브레이크 열분산장치를 첨부된 예시도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the disk brake heat dissipation device for a vehicle according to the present invention will be described in detail with reference to the accompanying drawings.
본 발명은 자동차의 디스크 브레이크장치에 있어서, 패드(52)와 접촉되지 않는 디스크(50)의 동심원상의 내측면 양쪽에 환형의 엠보싱부(10)을 갖추도록 한 구조로 되어 있다.In the disk brake apparatus of an automobile, the annular embossing part 10 is provided in both the concentric inner surfaces of the disk 50 which are not in contact with the pad 52.
예시도면 제4도는 본 발명에 따른 자동차의 디스크 브레이크장치의 디스크를 보인 정면도 및 측면도이다.4 is a front view and a side view showing a disk of a disk brake apparatus of a vehicle according to the present invention.
본 발명에 따른 자동차의 디스크 브레이크장치는 원판형상의 디스크(50)가 바퀴와 함께 회전할 수 있도록 중심부에 휘일의 허브와 결합되는 허브결합부(64)와, 유압피스톤으로 작용하는 패드(52)가 내장된 캘리퍼와, 디스크(50) 양쪽의 바깥쪽에 패드(52)가 디스크(50)와 접촉하도록 설치된 것으로써, 패드(52)와 접촉되지 않는 디스크(50)의 동심원상의 내측면에 표면적을 크게 할 수 있도록 돌기형상의 엠보싱부(10)를 형성시킨 구조로 되어 있다.The disc brake device of the vehicle according to the present invention has a hub coupling portion 64 coupled to the hub of the wheel at the center so that the disc-shaped disk 50 can rotate with the wheel, and the pad 52 acting as a hydraulic piston. And the pads 52 on both sides of the disk 50 so as to contact the disk 50, the surface area is formed on the inner surface of the concentric circle of the disk 50 that is not in contact with the pad 52. The protrusion embossed part 10 is formed so that it may enlarge.
상기와 같은 구조로된 본 발명에 따른 자동차의 디스크 브레이크장치의 작용 및 효과는 다음과 같다.The operation and effects of the disc brake device of the vehicle according to the present invention having the above structure are as follows.
본 발명에 따른 자동차의 디스크 브레이크장치는 캘리퍼내의 실린더에 유압을 작동시켜 피스톤에 의해 패드(52)를 밀어붙이면 디스크(50)는 양쪽에서 패드(52)에 의해 압착되어 마찰력에 의해 제동되며, 실린더내의 유압을 차단하면 피스톤은 피스톤 시일의 탄성변형에 의해 복원되려는 힘에 의해 피스톤의 원래의 위치로 돌아가게 되어 디스크와 패드 사이에 틈새가 발생되어 제동작용은 소멸되도록 이루어진 것이며, 이때 디스크(50)의 양측면에 패드(52)가 압착할때에 순간적으로 금속재질의 디스크(50)는 약 400도 가량의 고온으로 상승되는데 열전도가 공기중보다 디스크(50)의 동심원상의 패드(52)와 접촉하지 않는 내측면으로 더 빠르게 전달되어 공기중으로 방열될 때 디스크(50)의 동심원상의 패드(52)와 접촉하지 않는 내측면에는 표면적을 크게 할 수 있도록 엠보싱부(10)가 형성되어 열분산 효과와 함께 방열시간을 단축할 수 있도록 되는 것이다. 따라서 디스크가 고온에 노출되어 열변형을 일으켜 디스크의 변형이 발생되는 것을 억제할 수 있으므로 디스크의 변형으로 차가 정지할 때 스티어링이 떨리게 되는 현상을 방지하게 된 것이다.In the disc brake device of the vehicle according to the present invention, when the hydraulic pressure is applied to the cylinder in the caliper to push the pad 52 by the piston, the disc 50 is pressed by the pad 52 on both sides and braked by the friction force. When the hydraulic pressure is blocked, the piston is returned to its original position by the force to be restored by the elastic deformation of the piston seal, so that a gap is generated between the disk and the pad, and the braking action is extinguished. When the pad 52 is squeezed on both sides of the disk, the metal disk 50 instantly rises to a high temperature of about 400 degrees, and the thermal conductivity does not contact the pad 52 on the concentric circle of the disk 50 than in the air. The surface area can be increased on the inner surface that is not in contact with the concentric pads 52 of the disk 50 when it is delivered to the inner surface more quickly and radiated to the air. So that the embossment 10 is formed will be to reduce the radiation time with the heat dissipation effect. Therefore, since the disk is exposed to high temperature to cause thermal deformation, the deformation of the disk can be suppressed, so that the steering is shaken when the vehicle is stopped due to the deformation of the disk.
따라서 본 발명에 따른 자동차의 디스크 브레이크 열분산장치는 디스크의 변형으로 인해 제동시 스티어링이 떨리게 되는 쥬더현상을 미연에 방지하여 운전자에게 쾌적한 주행환경을 제공할 수 있는 효과가 있다.Therefore, the disk brake heat dissipation device of the vehicle according to the present invention has an effect of providing a comfortable driving environment to the driver by preventing the judder phenomenon that the steering is shaken when braking due to the deformation of the disk.
