본 고안은 탄지부재를 갖춘 디스크 브레이크에 관한 것으로, 더 상세하게는 디스크 브레이크의 제동이 완료되면 디스크의 양측을 협지하던 패드를 원위치시키는 탄지부재의 구조를 개선하여 디스크 쪽으로부터 패드를 신속히 이탈시키고, 또한 탄지부재의 내구성을 향상시켜 수명을 연장할 수 있는 패드플레이트의 탄지부재에 관한 것이다.The present invention relates to a disc brake having a stop member, and more particularly, when the braking of the disc brake is completed, by improving the structure of the stop member to reposition the pad that pinched the both sides of the disc to quickly release the pad from the disc side, The present invention also relates to a pad member of the pad plate, which can prolong the life by improving the durability of the pad member.
일반적으로 차량에 장착되는 브레이크는 주행 중의 자동차를 감속하거나 정지 또는 정지 상태를 유지하기 위한 장치이다.In general, a brake mounted on a vehicle is a device for decelerating, stopping or maintaining a stopped state of a vehicle while driving.
이러한 기능을 하는 브레이크는 주행 중의 운동에너지를 기계적인 마찰장치에 의해서 열에너지로 바꾸어 그의 마찰열을 대기중에 방출하여 제동을 하는 방식으로써, 드럼식 유압 브레이크와 디스크식 유압 브레이크 등이 있는데, 이 디스크 브레이크는 드럼 대신에 휠과 더불어 회전하는 원판형의 디스크를 양쪽에서 패드로 강하게 압박하여 제동력을 얻는 것이다.The brake that functions as this is a method of converting the kinetic energy while driving into thermal energy by the mechanical friction device to release the frictional heat to the air and braking. There are a drum hydraulic brake and a disk hydraulic brake. Instead, the disks, which are rotating along with the wheels, are strongly pressed against the pads on both sides to obtain braking force.
제1도는 디스크 브레이크의 전체적인 구성을 보인 개략도이다.1 is a schematic view showing the overall configuration of a disc brake.
디스크 브레이크는 도시한 바와 같이, 캐리어(10)의 설치홈(11)에 진퇴운동을 할 수 있도록 일정한 간격으로 이격된 패드(51a,52a)가 부착된 한 쌍의 패드플레이트(50)가 설치된다. 이 한 쌍의 패드플레이트(50)는 인너(INNER)패드플레이트(51)와 아웃터(OUTER)패드플레이트(52)로 구별되는데, 한 쌍의 패드플레이트(50) 사이에는 일부삽입되어 패드(51a,52a)와 일정한 간극을 두고 휠(미도시)과 더불어 회전하는 원판형의 디스크(60)가 설치된다.As shown in the figure, a pair of pad plates 50 having pads 51a and 52a spaced at regular intervals are installed in the installation groove 11 of the carrier 10 so as to move forward and backward. . The pair of pad plates 50 are divided into an inner pad plate 51 and an outer pad plate 52, and partially inserted between the pair of pad plates 50 to form pads 51a, 52a) and a disk 60 of a disk-shaped to rotate with a wheel (not shown) is provided with a predetermined gap.
그리고, 디스크 브레이크의 몸체를 이루는 하우징(20)이 실린더(22)에는 인너패드플레이트(51)의 일측과 결합되어 마스터 실린더(미도시)의 유압에 의해 이를 진퇴운동시키는 피스톤(30)이 설치되고, 실린더(22)의 상부에는 유압을 안내하는 유입구(21)가 마련되어 있다.In addition, the housing 20 forming the body of the disc brake is coupled to one side of the inner pad plate 51 to the cylinder 22, and a piston 30 is installed to move it back and forth by hydraulic pressure of a master cylinder (not shown). In the upper portion of the cylinder 22, an inlet 21 for guiding hydraulic pressure is provided.
한편, 실린더(22)의 내주면에는 환형의 홈(32)이 마련되어 있고 이 홈(32)에는 고무재질의 시일(31)이 피스톤(30)의 외주면과 밀접하게 접하여 설치되어 있는데, 액압을 해제하게 되면 시일(31)의 복원력에 의해 피스톤(30)이 복원되도록 구성된다.On the other hand, the inner circumferential surface of the cylinder 22 is provided with an annular groove 32, and the rubber seal 31 is provided in close contact with the outer circumferential surface of the piston 30, so as to release the hydraulic pressure. When the piston 30 is restored by the restoring force of the seal 31.
이 때 인너패드플레이트(51)와 피스톤(30)은 롤 백(33, roll back)으로 결합되어 있어서, 피스톤(30)이 복원될 때 동시에 인너패드플레이트(51)도 디스크(60)의 측면으로 부터 분리된다.At this time, the inner pad plate 51 and the piston 30 are coupled to the roll back 33 so that the inner pad plate 51 also moves to the side of the disk 60 at the same time when the piston 30 is restored. To be separated.
또한, 피스톤(30)이 설치되는 하우징(20)과 패드플레이트(50)가 설치된 캐리어(10)는 슬라이딩부재(40)로 결합되어 일체로 구성된다.In addition, the housing 20 in which the piston 30 is installed and the carrier 10 in which the pad plate 50 is installed are integrally combined with the sliding member 40.
이와 같이 구성된 디스크 브레이크를 갖춘 자동차의 주행시, 브레이크 페달(미도시)을 밟게 되면 마스터 실린더(미도시)로 부터 유압이 작용하게 되고 계속하여 이 유압은 하우징(20)의 유입구(21)를 통해 실린더(22) 내로 전달된다.When driving a vehicle having a disc brake configured as described above, when the brake pedal (not shown) is pressed, hydraulic pressure is applied from the master cylinder (not shown), and the hydraulic pressure is continuously applied to the cylinder through the inlet 21 of the housing 20. Is passed into (22).
따라서, 이 유압에 의해 피스톤(30)은 패드(51a)가 부착된 인너패드플레이트(51)를 순간적으로 디스크(60)에 압착함과 동시에, 실린더(22)에 유압이 존재하기 때문에 이것에 의해 슬라이딩 가능한 패드(52a)가 부착된 아웃터패드플레이트(52)가 설치홈(11)에서 슬라이딩하여 디스크(60)에 압착함으로써 제동작용을 한다.Therefore, the piston 30 presses the inner pad plate 51 on which the pad 51a is attached to the disk 60 by this hydraulic pressure, and at the same time, the hydraulic pressure is present in the cylinder 22. The outer pad plate 52 to which the slidable pad 52a is attached slides in the installation groove 11 to press the disc 60 to brake.
그러나, 이와 같은 종래의 디스크 브레이크에서는 다음과 같은 문제점이 발생한다.However, the following problem occurs in such a conventional disc brake.
제동시 브레이크 페달을 밟으면 마스터 실린더에서 유압이 피스톤(30)에 작용하게 되고 이 피스톤(30)에 의해 패드플레이트(51,52)의 패드(51a,52a)가 디스크(60)의 외측면과 강하게 밀착되며 제동을 수행한다. 그리고, 브레이크 패달을 떼면 디스크(60) 외측면에 밀착되었던 패드(51a,52a)가 디스크(60)와 이격되어 최초의 상태대로 다시 원위치 해야 되는데, 패드(51a,52a)가 디스크(60) 쪽에서 쉽게 이격되지 않아 패드(51a,52a)가 마찰 손상을 입게 되는 문제점이 있었다.When the brake pedal is pressed during braking, hydraulic pressure acts on the piston 30 in the master cylinder, which causes the pads 51a and 52a of the pad plates 51 and 52 to be strongly connected to the outer surface of the disk 60. Close contact and braking. Then, when the brake pedal is released, the pads 51a and 52a that are in close contact with the outer surface of the disk 60 should be spaced apart from the disk 60 and returned to their original state. The pads 51a and 52a should be in the original state. Since the pads 51a and 52a are not easily spaced apart, there is a problem in that the friction is damaged.
이러한 결점을 보완하기 위해 종래에는 제2도에 도시한 바와 같이, 패드플레이트(50)의 상부 양측에 각각 굴곡된 탄성부재(70)를 설치하였다. 이 탄성부재(70)는 패드플레이트(50)의 양측에 제1탄성부재(71)와 제2탄성부재(72)로 구성되어 있는데, 각각이 탄성부재(71,72)는 그 일단이 인너패드플레이트(51)의 가장자리에 설치되고 타단은 아웃터패드플레이트(52)의 상응하는 부분에 고정시켰다.In order to make up for this drawback, conventionally, as shown in FIG. The elastic member 70 is composed of a first elastic member 71 and a second elastic member 72 on both sides of the pad plate 50, each of the elastic members 71 and 72, one end of the inner pad It was installed at the edge of the plate 51 and the other end was fixed to the corresponding part of the outer pad plate 52.
따라서, 이 탄성부재(70)의 탄성 복원력에 의해 패드플레이트(50)를 강제적으로 원위치시키는 것이다.Therefore, the pad plate 50 is forcibly returned by the elastic restoring force of the elastic member 70.
그러나, 이러한 종래의 탄성부재(70)은 탄성 복원력이 약해서 제 기능을 충분히 수행하지 못하게 되고, 탄성부재(70)의 절곡부위가 쉽게 파손되어 내구성이 저하되고이에 따른 수명이 저하되었다.However, the conventional elastic member 70 has a weak elastic restoring force, so that it is not able to sufficiently perform its function, and the bending portion of the elastic member 70 is easily broken, so that durability is lowered and its lifetime is lowered.
또한, 원상태로 복귀되지 못한 패드플레이트(50)의 패드(51a,52a)는 고속으로 회전하는 디스크(60)의 측면과 마찰하며 이격되는데, 이 마찰로 인해서 패드(51a,52a)가 쉽게 마모된다.In addition, the pads 51a and 52a of the pad plate 50, which are not returned to their original state, are separated from each other by friction with the side surfaces of the disk 60 that rotates at high speed, and the friction causes the pads 51a and 52a to be easily worn. .
본 고안은 이러한 문제점을 해결하기 위한 것으로, 본 고안의 목적은 제동이 완료된 후 패드플레이트를 원상태로 복귀시키는 탄지부재의 구조를 개선하여 디스크 쪽으로부터 패드를 신속히 이탈시킴으로써, 패드의 마모손상을 줄이고 또한 탄지부재의 내구성을 향상시켜 수명을 연장시키는 탄지부재를 갖춘 디스크 브레이크를 제공하는 것이다.The present invention is to solve this problem, the object of the present invention is to improve the structure of the support member for returning the pad plate to the original state after the braking is completed by quickly releasing the pad from the disk side, reducing the wear damage of the pad It is to provide a disc brake having a finger member to improve the durability of the finger member to extend the life.
이러한 목적을 달성하기 위한 본 고안은, 디스크 브레이크의 하우징, 하우징에 내설되어 진퇴운동하는 피스톤, 피스톤에 의해 작동하는 패드가 부착된 한 쌍의 패드플레이트, 패드플레이트가 슬라이딩이 가능하도록 설치되는 설치홈이 마련된 케리어, 케리어와 하우징을 결합하는 슬라이딩 부재, 패드플레이트 사이에 일부가 삽입되어 회전하는 디스크를 갖춘 디스크 브레이크에 있어서, 패드플레이트에는 그 양단이 벤딩되어 그 일단은 패드플레이트의 단부에 결합되고 그 타단은 설치홈에 압착지지되어 패드플레이트를 디스크로부터 외향지지하는 탄지부재가 마련되는 것을 특징으로 한다.The present invention for achieving this purpose, the housing of the disc brake, the piston in the housing to move forward and backward, a pair of pad plate attached to the pad actuated by the piston, the installation groove is installed so that the pad plate is slidable A disc brake having a provided carrier, a sliding member for coupling a carrier and a housing, and a disc rotating with a part inserted between the pad plates, wherein both ends of the pad plate are bent and one end thereof is joined to an end of the pad plate. The other end is crimped and supported by the installation groove is characterized in that the support member for supporting the pad plate outward from the disk is provided.
이하, 본 고안에 따른 하나의 바람직한 실시예를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings.
제3도는 본 고안에 따른 디스크 브레이크를 도시한 것이다.(본 고안에 따른 디스크 브레이크는 패드플레이트를 외향 탄지하여 액압 해제시 이를 복원시키는 탄지부재의 구조를 제외하고는 종래의 구성요소와 동일하기 때문에 동일구성요소에 대해서는 동일명칭과 동일부호를 사용하여 간략하게 설명한다.)3 shows the disc brake according to the present invention. (The disc brake according to the present invention is the same as a conventional component except for the structure of the finger member which restrains the pad plate outward and restores it when the hydraulic pressure is released. The same components will be briefly described using the same names and the same reference numerals.)
이에 도시한 바와 같이, 케리어(10)의 설치홈(11)에는 패드(51a,62a)가 부착된 한 쌍의 패드플레이트(50)가 진퇴운동이 가능하도록 일정간격 이격되어 설치되고, 이 패드플레이트(50) 사이에는 일부삽입되어 휠과 더불어 회전하는 디스크(60)가 구성된다.As shown in the figure, a pair of pad plates 50 to which the pads 51a and 62a are attached to the installation grooves 11 of the carrier 10 are spaced apart at regular intervals to enable the forward and backward movement. A disc 60 is inserted between the parts 50 to rotate together with the wheel.
그리고 디스크 브레이크의 몸체를 이루는 하우징(20)에는 유압을 안내하는 유입구(21)가 마련된 실린더(22)와, 이 실린더(22)에는 유압에 의해 진퇴운동하는 피스톤(30)이 마련되고, 실린더(22)의 내주면에는 환형의 홈(32)과 이 홈에(32) 시일(31)이 마련되어 액압 해제시 시일(31)의 복원력에 의해 피스톤(30)이 복원된다. 한편, 인너패드플레이트(51)와 피스톤(30)은 롤 백(33)으로 결합되어 피스톤(30)의 작동에 따라 인너패드플레이트(51)도 동시에 움직이고, 패드플레이트(50)가 설치된 케리어(10)에는 하우징(20)이 슬라이딩부재(40)에 의해 슬라이딩이 가능하게 체결되어 있다.The housing 20 constituting the body of the disc brake is provided with a cylinder 22 provided with an inlet 21 for guiding hydraulic pressure, and the cylinder 22 is provided with a piston 30 for moving back and forth by hydraulic pressure. An annular groove 32 and a seal 31 in the groove 32 are provided on the inner circumferential surface of 22 to restore the piston 30 by the restoring force of the seal 31 when the hydraulic pressure is released. Meanwhile, the inner pad plate 51 and the piston 30 are coupled to the roll back 33 so that the inner pad plate 51 also moves simultaneously with the operation of the piston 30, and the carrier plate 10 having the pad plate 50 installed thereon. ) Is coupled to the housing 20 so as to be slidable by the sliding member 40.
또한, 본 고안의 특징적인 요소로, 아웃터패드플레이트(52)의 단부에는 이를 디스크(60)로 부터 외향 탄지하는 탄지부재(80)가 마련되어 있다.In addition, as a characteristic element of the present invention, at the end of the outer pad plate 52 is provided with a finger member 80 for gripping outwardly from the disk 60.
이 탄지부재(80)는 판상으로 되어 그 양단이 벤딩되더 있는데, 일단은 아웃터패드플레이트(52)의 단부에 고정 결합되고 벤딩된 타단은 아웃터패드플레이트(52)가 삽입결합된 케리어(10)의 설치홈(11)에 단순히 억지끼움되어 그 탄성력으로 인해 압착지지되어 있다.The finger member 80 has a plate shape, and both ends thereof are bent, and one end is fixedly coupled to the end of the outer pad plate 52, and the other end of the outer finger plate 52 is inserted into and coupled to the outer pad plate 52. It is simply pressed into the installation groove 11 and is crimped and supported by its elastic force.
따라서 아춧터패드플레이트(52)가 벤딩된 판상으 탄지부재(80)의 복원력으로 의해 본래의 위치로 복원되도록 구성되어 있다.Therefore, the abutment pad plate 52 is configured to be restored to its original position by the restoring force of the plate-shaped finger member 80 which is bent.
이와 같이 구성된 본 고안에 따른 디스크 브레이크의 제동작용은 종래의 작용과 동일하기 때문에 이에 대한 설명은 생략한다.Since the braking action of the disc brake according to the present invention configured as described above is the same as the conventional action, a description thereof will be omitted.
다만, 본 고안의 특징적인 작용은 다음과 같다.However, the characteristic operation of the present invention is as follows.
양단이 벤딩된 판상의 탄지부재(80)는 이 일단이 아웃터패드플레이트(52)의단부에 결합되고 타단은 아웃터패드플레이트(52)가 결합된 설치홈(11)에 단순히 접촉지지되어 있다.The plate-shaped finger member 80, which is bent at both ends, is coupled to the end of the outer pad plate 52, and the other end is simply contacted and supported by the installation groove 11 to which the outer pad plate 52 is coupled.
따라서 아웃터패드플레이트(52)는 설치홈(11)에서 벤딩된 탄지부재(80)에 의해 탄지결합되어 있어서, 제동시에는 아웃터패드플레이트(52)는 디스크(60)의 측면과 압착하고 액압이 해제되면 탄지부재(80)의 복원력에 의해 원래의 위치로 복원된다.Therefore, the outer pad plate 52 is finger-tightly coupled by the support member 80 bent in the installation groove 11, so that during braking the outer pad plate 52 is pressed against the side of the disk 60 and the hydraulic pressure is released. When it is restored to the original position by the restoring force of the finger member 80.
이러한 작용이 반복되면 디스크(60)와 접촉하는 패드(52a)가 마모되어 패드플레이트(52)가 움직이는 갭(GAP)이 커지게 되고, 따라서 아웃터패드플레이트(52)의 슬라이딩 폭이 커지게 되는데, 탄지부재(80)의 타단은 설치홈(11)의 접촉지지되는 점에서 그 내측으로 커진 갭만큼 슬라이딩되고 다시 아웃터패드플레이트(52)를 디스크(60)로부터 외향 탄지한다.When this action is repeated, the pad 52a in contact with the disk 60 wears out, thereby increasing the gap GAP through which the pad plate 52 moves, thus increasing the sliding width of the outer pad plate 52. The other end of the holding member 80 is slid by the gap enlarged inward at the point where the supporting groove 11 is in contact and supported, and again holds the outer pad plate 52 outward from the disk 60.
따라서 본 고안에 따른 탄지부재(80)는 지지되는 점이 설치홈(11)에서 슬라이딩 가능하여 패드(52a)가 마모되어도 항상 같은 복원력으로 아웃터패드플레이트(52)를 디스크(60)로 부터 외향 지지함으로써, 액압 해제시 패드(52a)와 디스크(60)의 불필요한 마찰이 줄어들게 되어 패드(52a)의 마찰 손상이 감소된다.Therefore, the support member 80 according to the present invention is slidable in the mounting groove 11 so that the outer pad plate 52 is always supported outward from the disk 60 with the same restoring force even when the pad 52a is worn. When the hydraulic pressure is released, unnecessary friction between the pad 52a and the disk 60 is reduced, thereby reducing the frictional damage of the pad 52a.
즉, 마찰에 의한 소음이 줄어들고, 패드(52a)이 수명이 연장되게 된다.That is, the noise due to friction is reduced, and the pad 52a is extended in life.
이상에서 상세히 설명한 바와 같이, 본 고안에서는 아웃터패드플레이트를 복원시키기 위해 양단이 벤딩된 판상의 탄지부재가 마련되어 있는데, 이 탄지부재의 일단은 아웃터패드플레이트의 단부에 결합되고 타단은 설치홈에 억지끼움되어 아웃터패드플레이트를 디스크로부터 외향 지지하도록 구성된다.As described in detail above, in the present invention, there is provided a plate-like fingerboard member bent at both ends to restore the outer pad plate, one end of which is coupled to the end of the outer pad plate and the other end is fitted into the installation groove. And to support the outer pad plate outward from the disk.
따라서 액압 해제시 아웃터패드플레이트를 빨리 복원시킴으로써, 불필요한 마찰 손상을 줄여 패드의 수명이 연장되고 브레이크의 떨림현상이 개선되는 이점이 있다.Therefore, by restoring the outer pad plate at the time of releasing the hydraulic pressure, there is an advantage in that unnecessary friction damage is reduced, thereby prolonging the life of the pad and improving shaking of the brake.
