Description
본 고안은 차량용 디스크브레이크에 관한 것으로, 더 상세하게는 캐리어에 슬라이딩 가능하게 결합되는 하우징을 개선하여 브레이킹시 브레이크의 슬라이딩 저항을 감소시킨 차량용 디스크브레이크에 관한 것이다.The present invention relates to a vehicle disk brake, and more particularly, to a vehicle disk brake that has improved the housing slidably coupled to the carrier to reduce the sliding resistance of the brake during braking.
도 1은 일반적인 디스크 브레이크의 일부분해 사시도로서 이를 간단히 설명한다. 차량의 적소에 고정된 캐리어(1)가 마련되고 캐리어에는 내,외측 패드(2a,2b)가 일정간격을 가지며 안치된다. 패드(2) 사이에는 차량의 휠과 동일하게 회전되는 디스크(20)의 일부가 위치되고 캐리어에는 하우징(3)이 결합된다.1 is a partial perspective view of a typical disc brake, briefly explaining it. The carrier 1 fixed in place of the vehicle is provided, and the inner and outer pads 2a and 2b are placed at regular intervals. A portion of the disk 20 which is rotated in the same way as the wheel of the vehicle is located between the pads 2 and the housing 3 is coupled to the carrier.
하우징(3)은 캐리어(1)를 감싸는 형태로 슬라이딩 가능하게 결합되는데,상세히 설명한다. 캐리어(1)의 양측면에는 가이드로드(6)가 삽입되는 삽입로(1a)가 형성되고 가이드로드(6)의 머리부에는 결합로(6a)가 형성된다. 그리고 하우징(3)의 양측면에는 관통공(3a)이 형성되는데,이 관통공(3a)으로는 가이드로드볼트(5)가 관통되어 가이드로드의 결합로(6a)에 결합된다. 미설명부호 7은 실린더이고, 8은 피스톤이며, 9는 가이드로드부트이다.The housing 3 is slidably coupled in a form surrounding the carrier 1, which will be described in detail. Inserting passages 1a through which guide rods 6 are inserted are formed at both side surfaces of the carrier 1, and coupling paths 6a are formed at the head of the guide rod 6. And through holes (3a) are formed on both sides of the housing (3), the guide rod bolt (5) is passed through the through hole (3a) is coupled to the coupling path (6a) of the guide rod. Reference numeral 7 is a cylinder, 8 is a piston, and 9 is a guide rod boot.
상기와 같은 종래의 디스크브레이크는 가이드로드가 캐리어의 삽입로에 편심되게 설치되어 브레이킹시 슬라이딩 저항이 증가되는 단점이 있었다. 상세히 설명하면,가이드로드와 가이드로드볼트는 나사결합되어 있는데,가이드로드 결합로(6a)의 나사 및 조립관련 부분의 가공공차와 하우징 관통공(3a)의 가공정도에 따라서 가이드로드는 그 일측이 도 2와 같이 편심되어져 삽입로의 내주면과 접촉되게 된다. 그러면 브레이킹시 하우징이 슬라이딩될 때 슬라이딩 저항을 많이받게 되므로 브레이크에 떨림 및 소음이 발생되어 브레이크의 성능이 저하되는 단점이 있었다.The conventional disc brake as described above has a disadvantage in that the guide rod is eccentrically installed in the insertion path of the carrier and the sliding resistance is increased during the braking. In detail, the guide rod and the guide rod bolt are screwed together. According to the machining tolerances of the screw and assembly-related parts of the guide rod coupling passage 6a and the degree of machining of the housing through hole 3a, the guide rod has one side thereof. It is eccentric as shown in FIG. 2 and comes into contact with the inner peripheral surface of the insertion path. Then, when the housing is slid during braking, a lot of sliding resistance is received, so that vibration and noise are generated in the brake, thereby degrading the performance of the brake.
본 고안은 상기의 단점을 해소하기 위하여 안출된 것으로, 본 고안의 목적은 하우징에 가이드로드의 단부가 안치되는 안치홈을 형성하여 가이드로드가 편심되지 않도록 함으로서, 브레이킹시 브레이크의 떨림 및 소음을 저감시킬 수 있음과 동시에 브레이크의 성능을 향상시킬 수 있는 차량용 디스크브레이크를 제공함에 있다.The present invention is devised to solve the above disadvantages, an object of the present invention is to form a settling groove in which the end of the guide rod is placed in the housing so that the guide rod is not eccentric, thereby reducing vibration and noise of the brake during braking. In addition, the present invention provides a disc brake for a vehicle that can improve the performance of the brake.

상기 하우징에는 상기 가이드로드의 결합로측이 안치되어 가이드로드가 하우징에 대하여 수직상태를 유지하도록 하기 위한 안치홈이 상기 관통공과 연통되게 형성된 구성이다.In the housing, a side of the coupling path of the guide rod is settled so that a guide groove for maintaining the guide rod perpendicular to the housing is formed in communication with the through hole.
이하 첨부한 도면에 의하여 본 고안에 따른 차량용 디스크브레이크의 바람직한 실시예를 상세히 설명한다.Hereinafter, preferred embodiments of a vehicular disk brake according to the present invention will be described in detail with reference to the accompanying drawings.
본 고안에 따른 디스크브레이크는 도 3에 도시하듯이,차량의 적소에 고정되는 캐리어(51)가 마련된다. 상기 캐리어(51)에는 마찰재인 내,외측패드(52a,52b)가 일정간격을 가짐과 동시에 대향되게 안치되고 상기 패드(52) 사이에는 디스크(20)의 일측이 위치된다. 상기 디스크는 차량의 휠과 연결되어 휠과 동일하게 회전된다. 상기 캐리어(51)에는 캐리어를 감싸는 형태로 하우징(53)이 결합되는데,상기 하우징(53)은 슬라이딩 가능하게 결합된다. 그리고 상기 하우징(53)의 배면측에는 피스톤(58)이 내장된 실린더(57)가 마련된다. 상기 피스톤(58)은 브레이크페달에 외력이 작용되면 내측패드(52a)를 밀어서 회전중인 디스크(20)에 접촉되게 한다.Disc brake according to the present invention, as shown in Figure 3, is provided with a carrier 51 fixed in place of the vehicle. The inner and outer pads 52a and 52b, which are friction materials, are placed in the carrier 51 so as to face each other at the same time, and one side of the disk 20 is positioned between the pads 52. The disk is connected to the wheel of the vehicle and rotated in the same manner as the wheel. The housing 53 is coupled to the carrier 51 in a form surrounding the carrier, and the housing 53 is slidably coupled. And the cylinder 57 in which the piston 58 is built is provided in the back side of the said housing 53. As shown in FIG. The piston 58 is in contact with the rotating disk 20 by pushing the inner pad (52a) when an external force is applied to the brake pedal.
캐리어(51)와 하우징(53)의 결합구조를 설명하면,상기 캐리어(51)의 양측면에는 삽입로(51a)가 형성되고 상기 하우징(53)의 양측면에는 상기 삽입로(51a)에 대응되는 관통공(53a)이 형성된다. 상기 삽입로(51a)에는 가이드로드(56)가 삽입되는데,상기 가이드로드(56)는 몸체(56a)와 머리부(56b)를 가지며 상기 몸체가 삽입로에 삽입된다. 그리고 상기 머리부(56b)에는 결합로(56c)가 형성되는데,상기 결합로(56c)의 내주면에는 나사가 형성된다. 상기 관통공(53a)으로는 가이드로드볼트(55)가 관통되어 가이드로드(56)의 결합로(56c)에 결합된다. 그리고 가이드로드와 하우징 사이에는 신축성을 가진 가이드로드부트(59)가 마련된다. 상기 가이드로드부트(59)는 가이드로드가 캐리어의 삽입로에 조립되었을 때,상대 슬라이딩 부위로 이물질이 침입되는 것을 방지하여 슬라이딩저항이 증가되는 것을 방지한다.When the coupling structure of the carrier 51 and the housing 53 is described, insertion paths 51a are formed on both sides of the carrier 51 and through holes corresponding to the insertion paths 51a on both sides of the housing 53. The ball 53a is formed. A guide rod 56 is inserted into the insertion passage 51a, and the guide rod 56 has a body 56a and a head 56b and the body is inserted into the insertion passage. And the coupling portion 56c is formed in the head portion 56b, and a screw is formed on the inner circumferential surface of the coupling passage 56c. The guide rod bolt 55 passes through the through hole 53a and is coupled to the coupling path 56c of the guide rod 56. In addition, a guide rod boot 59 having elasticity is provided between the guide rod and the housing. The guide rod boot 59 prevents foreign matter from entering the relative sliding portion when the guide rod is assembled in the insertion path of the carrier, thereby preventing the sliding resistance from increasing.
본 고안에 따른 디스크브레이크의 하우징에는 안치홈(53b)이 형성되는데,상기 안치홈(53b)은 가이드로드가 하우징에 대하여 편심되지 않고 수직상태를 유지하게 한다. 상세히 설명하면,상기 하우징(53)에는 관통공(53a)과 연통되는 안치홈(53b)이 형성되는데,상기 안치홈(53b)은 가이드로드의 머리부(56b)와 동일크기 동일형상으로 형성된다. 그리고 상기 머리부(56b)가 안치홈(53b) 안치되면 관통공(53a)과 결합로(56c)가 연통되도록 안치홈(53b)은 형성된다. 상기 가이드로드(56)가 안치홈에 억지로 끼워지면 가이드로드는 하우징에 대하여 수직상태를 유지하게 된다. 이때,가이드로드볼트(55)를 관통공으로 관통시켜 가이드로드와 결합시키고 가이드로드를 캐리어의 삽입로(51a)에 삽입하면 된다. 그러면 가이드로드는 삽입로에 편심되지 않은 채로 삽입되어 있는 것이다.Settle groove 53b is formed in the housing of the disc brake according to the present invention. The settle groove 53b allows the guide rod to maintain a vertical state without being eccentric with respect to the housing. In detail, the housing 53 is provided with a settling groove 53b communicating with the through hole 53a. The settling groove 53b is formed in the same shape and the same size as the head 56b of the guide rod. . And when the head 56b is settled in the settling groove 53b, the settling groove 53b is formed so that the through hole 53a and the coupling passage 56c communicate with each other. When the guide rod 56 is forcibly inserted into the settling groove, the guide rod 56 is maintained perpendicular to the housing. At this time, the guide rod bolt 55 may be penetrated through the through hole to be coupled to the guide rod, and the guide rod may be inserted into the insertion path 51a of the carrier. The guide rod is then inserted uneccentrically into the insertion path.
상기와 같은 구조의 본 고안에 따른 디스크브레이크의 작용을 간단히 설명한다.The operation of the disc brake according to the present invention having the above structure will be described briefly.
브레이크페달(미도시)에 외력이 작용되면 액압이 하우징의 배면에 형성된 실린더(57)로 전달되어 실린더에 내장된 피스톤(58)을 내측패드(52a) 측으로 밀어준다. 그러면 내측패드(52a)가 회전중인 디스크(20)에 접촉되는데,내측패드가 디스크에 접촉되어 더 이상 전진할 수 없어도 피스톤은 내측패드를 계속하여 밀고 있다. 그러면 하우징(53)이 실린더(57)측으로 이동되면서 외측패드(52b)를 함께 이동시켜서 외측패드(52b)가 디스크에 접촉되도록 한다. 그리고 브레이크페달에 작용되는 외력이 제거되면 피스톤(58)과 내측패드(52a)는 후퇴되고,하우징(53)은 피스톤(58)의 타측으로 이동된다. 이러한 작용에 의하여 차량이 제동되는 것이다.When an external force is applied to the brake pedal (not shown), the hydraulic pressure is transmitted to the cylinder 57 formed on the rear surface of the housing to push the piston 58 embedded in the cylinder toward the inner pad 52a. The inner pad 52a is then in contact with the rotating disk 20. The piston continues to push the inner pad even when the inner pad is in contact with the disk and can no longer be advanced. Then, the housing 53 is moved to the cylinder 57 side to move the outer pad 52b together so that the outer pad 52b contacts the disk. When the external force applied to the brake pedal is removed, the piston 58 and the inner pad 52a are retracted, and the housing 53 is moved to the other side of the piston 58. The vehicle is braked by this action.
그리고 본 고안에 따른 디스크브레이크는 가이드로드가 하우징의 안치홈(53b)에 안치되어 있으므로 가이드로드는 하우징에 대하여 수직상태를 유지한다. 그러므로 가이드로드는 삽입로의 내부에서 편심되지 않은 상태로 위치해 있게 되는 것이다.(도 4참조)In addition, the disc brake according to the present invention, since the guide rod is placed in the settled groove 53b of the housing, the guide rod maintains a perpendicular state to the housing. Therefore, the guide rod is to be located uneccentrically inside the insertion path (see Fig. 4).
이상에서 설명하듯이 본 고안에 따른 차량용 디스크브레이크는, 하우징의 안치홈에 가이드로드가 안치되어 항상 하우징에 대하여 수직상태를 유지하므로 가이드로드는 삽입로 내부에서도 편심되지 않은 상태를 유지한다. 그러므로 브레이킹시 브레이크의 떨림 및 소음이 저감되는 특징이 있고,또 브레이크의 성능이 향상된 특징이 있다.As described above, the vehicle disc brake according to the present invention, the guide rod is placed in the settling groove of the housing and always maintains a vertical state with respect to the housing, so that the guide rod is not eccentric even inside the insertion path. Therefore, vibration and noise of the brake are reduced during braking, and the brake performance is improved.
