Abstract
본 발명은 디스크 브레이크의 캘리퍼 하우징에 관한 것으로, 그 목적은 캘리퍼 하우징의 보어를 패드의 중심선에 대해 편심되게 가공하여 패드의 편마모를 방지하는 것이다.The present invention relates to a caliper housing of a disc brake, and its object is to process the bore of the caliper housing eccentrically with respect to the center line of the pad to prevent uneven wear of the pad.
본 발명에 따른 디스크 브레이크의 캘리퍼 하우징에 의하면, 패드(41)(51)의 중심선(D1)을 기점으로 피스톤(13)이 진퇴운동 가능하게 설치되는 보어(11)를 디스크(30)의 전진방향측으로 편심되게 가공하여 피스톤(13)의 압력이 전진방향 출구측에 상대적으로 강하게 가해짐으로써, 실제 제동작용 시 패드(41)(51)의 마모상태가 전체적으로 보다 균일하게 이루어져 내구성이 증대되고 제동소음이 감소하여 전체적인 디스크 브레이크의 신뢰성이 보다 향상되는 이점이 있다.According to the caliper housing of the disc brake according to the present invention, the bore 11 in which the piston 13 is installed to move forward and backward from the center line D1 of the pads 41 and 51 is moved forward.

This reduction has the advantage that the reliability of the overall disc brake is further improved.
Description
본 발명은 디스크 브레이크에 관한 것으로, 더욱 상세하게는 제동유압에 의해 피스톤이 진퇴운동 가능하게 설치되도록 보어가 형성된 디스크 브레이크의 캘리퍼 하우징에 관한 것이다.The present invention relates to a disc brake, and more particularly, to a caliper housing of a disc brake in which a bore is formed so that the piston can be installed to move forward and backward by braking hydraulic pressure.
차량에 장착되는 브레이크는 드럼식 유압 브레이크와 디스크식 유압브레이크등이 있다.The brakes mounted on the vehicle include a drum hydraulic brake and a disk hydraulic brake.
종래 디스크 브레이크는 드럼 대신에 휠과 함께 회전하는 원판형의 디스크를 양쪽에서 패드로 강하게 압박하여 제동력을 얻는 것으로, 휠과 함께 회전운동하는 디스크, 디스크의 양측면에 설치된 한쌍의 패드플레이트, 피스톤이 내장된 캘리퍼 하우징을 구비한다.Conventional disc brakes obtain a braking force by strongly pressing a disk-shaped disk that rotates together with a wheel instead of a drum with pads on both sides, and a disk that rotates with the wheel, a pair of pad plates installed on both sides of the disk, and a piston A caliper housing.
캘리퍼 하우징은 후방부 중심에 피스톤이 진퇴운동할 수 있도록 가공된 보어와 전방부에 하측방향으로 굽어지게 형성되어 후술하는 아웃터패드플레이트를 감싸는 핑거부를 구비한다. 보어의 내주면에는 제동유압이 해제되면 피스톤을 복원시키도록 탄성재질의 시일이 설치되며, 이러한 보어를 중심으로 캘리퍼 하우징은 좌우 대칭되게 마련된다.The caliper housing includes a bore processed to move the piston forward and backward at the center of the rear part and a finger part formed to be bent downward in the front part to surround the outer pad plate, which will be described later. The inner circumferential surface of the bore is provided with an elastic seal to restore the piston when the braking hydraulic pressure is released, the caliper housing is provided symmetrically around the bore.
패드플레이트는 차체에 장착되는 캐리어에 내측방향으로 유격가능하게 설치되는데, 일면에 인너패드가 부착되며 타면 중심부가 피스톤 선단과 접촉되게 배치되는 인너패드플레이트, 일면에 아웃터패드가 부착되며 타면은 핑거부 내면과 접하도록 배치되는 아웃터패드플레이트로 구별된다.The pad plate is installed in the carrier mounted on the vehicle body so as to be spaced inwardly. An inner pad is attached to one surface and an inner pad plate is disposed such that the center of the other surface is in contact with the piston tip. It is distinguished by an outer pad plate disposed to be in contact with the inner surface.
한편, 원판상으로 이루어진 디스크는 인너패드와 아웃터패드 사이에 외주 일부가 삽입되는데, 제동작용이 이루어지지 않는 경우에는 이들과 일정한 간극을 유지하면서 휠과 함께 회전운동한다.On the other hand, the disk-shaped disk is inserted into a portion of the outer circumference between the inner pad and the outer pad, when the braking action is not made, while maintaining a constant gap with them to rotate with the wheel.
이와 같이 구성된 디스크 브레이크를 갖춘 자동차가 주행하고 있는 상태에서 운전자가 브레이크패달을 밟게 되면, 마스터실린더에서 발생된 제동유압이 유압라인을 통해 보어 내부로 전달된다. 제동유압 전달에 의해 피스톤이 전진하여 인너패드플레이트가 디스크 측으로 밀림으로써, 인너패드가 디스크에 압착되어 제동력이 발생된다. 아울러 보어 내부에는 유압이 잔존하기 때문에 캘리퍼 하우징 자체가 반대방향으로 이동함으로써, 이것에 의해 핑거부가 아웃터패드플레이트를 디스크 측으로 밀고 아웃터패드는 디스크에 압착되어 제동력을 발휘한다.When the driver presses the brake pedal while the vehicle having the disc brake configured as described above is running, the braking hydraulic pressure generated in the master cylinder is transferred into the bore through the hydraulic line. The piston advances by braking hydraulic pressure and the inner pad plate is pushed to the disk side, whereby the inner pad is pressed against the disk to generate a braking force. In addition, since the hydraulic pressure remains inside the bore, the caliper housing itself moves in the opposite direction, whereby the finger portion pushes the outer pad plate to the disk side, and the outer pad is pressed against the disk to exert a braking force.
그리고 운전자가 브레이크패달에서 밟을 떼면, 피스톤은 시일의 탄성력으로 인해 복원되며, 인너패드와 아웃터패드는 다시 디스크로부터 일정간격 이격된다.When the driver steps on the brake pedal, the piston is restored due to the elasticity of the seal, and the inner pad and the outer pad are again spaced apart from the disk.
그러나 이러한 종래 디스크 브레이크는 계속적인 제동작용에 따라 디스크를 압착하는 패드가 도 1에 보인 바와 같이, 편마모되는 문제점이 발생된다.However, such a conventional disc brake has a problem that the pad which compresses the disc according to the continuous braking action is unevenly worn as shown in FIG. 1.
즉, 피스톤(1)에 의해 인너패드(2) 및 아웃터패드(3)가 화살표 A방향으로 회전(자동차가 전진하는 경우)하는 디스크(4)에 전체적으로 접촉하여도, 실제 디스크(4)에 가해지는 패드(2)(3)의 면압력은 디스크(4)의 회전토크에 의해 디스크(4) 진입측과 대응하는 후방측으로 집중된다.That is, even if the inner pad 2 and the outer pad 3 are in contact with the disk 4 rotating in the direction of arrow A (when the vehicle moves forward) by the piston 1, the inner pad 2 and the outer pad 3 are applied to the actual disk 4; The surface pressure of the losing pads 2 and 3 is concentrated by the rotational torque of the disk 4 toward the rear side corresponding to the entry side of the disk 4.
이에 따라 디스크 브레이크를 장시간 사용하면 패드(2)(3)의 마모상태가 중심선(B)에 대해 그 후방측으로 편중된다. 이러한 패드(2)(3)의 편마모현상은 제동성능 저하의 요인이 될 뿐만 아니라 패드(2)(3)와 디스크(4) 사이에서 발생되는 제동소음의 원인이 되고, 그 수명 또한 단축됨으로써 전체적인 디스크 브레이크의 신뢰성이 저하된다.Accordingly, when the disc brake is used for a long time, the wear state of the pads 2 and 3 is biased to the rear side with respect to the center line B. FIG. The wear and tear of the pads 2 and 3 not only causes deterioration of braking performance but also causes braking noise generated between the pads 2 and 3 and the disk 4, and the life of the pads is also shortened. The reliability of the disc brake is reduced.
본 발명은 이러한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 캘리퍼 하우징에 형성된 보어를 개선하여 패드의 편마모를 방지하며 제품 내구성과 신뢰성을 향상시킬 수 있는 디스크 브레이크의 캘리퍼 하우징을 제공하는 것이다.The present invention is to solve this problem, it is an object of the present invention to provide a caliper housing of a disc brake that can improve the bore formed in the caliper housing to prevent uneven wear of the pad and improve product durability and reliability.

이러한 목적을 달성하기 위한 본 발명은, 휠과 함께 회전하는 디스크, 디스크의 측면과 인접하게 배치되며 패드가 부착된 패드플레이트, 패드플레이트를 작동시키도록 제동유압에 의해 진퇴운동하는 피스톤, 피스톤이 설치되도록 후방부에 보어가 가공된 캘리퍼 하우징을 갖춘 디스크 브레이크에 있어서,In order to achieve the above object, the present invention provides a disk that rotates with a wheel, a pad plate attached to a side of the disk, and a piston attached to and retracted by braking hydraulic pressure to operate the pad plate. In a disc brake with a caliper housing bore-machined at the rear,
보어는 패드의 중심선을 기점으로 디스크의 전진회전 출구측으로 편심되게 가공된 것을 특징으로 하는 구성이다.The bore is a configuration characterized in that it is eccentrically machined to the forward rotation exit side of the disk starting from the center line of the pad.
이러한 구성에 의하면, 피스톤의 압력이 디스크의 전진방향 출구측으로 편심되게 가해지지만, 디스크의 회전토크에 의해 전체적으로 패드의 마모상태가 균일하게 이루어져 내구성과 신뢰성을 향상시킬 수 있다.According to this configuration, the pressure of the piston is eccentrically applied to the exit side of the disk in the forward direction, but the wear of the pad is uniform throughout by the rotational torque of the disk, thereby improving durability and reliability.
이하, 본 발명에 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.
본 발명에 따른 디스크 브레이크는 도 2에 도시한 바와 같이, 한쌍의 패드플레이트(40)(50)가 일정간격 이격되게 배치되며 차체에 고정되는 캐리어(20), 가장자리 일부가 패드플레이트(40)(50) 사이에 삽입되면서 휠(미도시)과 함께 회전하는 디스크(30), 제동유압에 의해 진퇴운동하도록 피스톤(13)이 내장된 캘리퍼 하우징(10)을 포함한다.In the disc brake according to the present invention, as shown in FIG. 2, a pair of pad plates 40 and 50 are arranged to be spaced apart at regular intervals, and the carrier 20 fixed to the vehicle body and a part of the edge of the pad plate 40 ( The disk 30 is inserted between the 50 and rotates together with the wheel (not shown), and the caliper housing 10 in which the piston 13 is built to move back and forth by the braking hydraulic pressure.
캐리어(20)는 차체의 너클에 볼트 고정되며, 여기에는 일면에 인너패드(41)가 부착된 인너패드플레이트(40)와 아웃터패드(51)가 부착된아웃터패드플레이트(50)가 디스크(30)를 중심으로 유격가능하게 길이방향으로 설치된다. 이 때, 인너패드플레이트(40)의 타면은 피스톤(13)의 선단과 접하도록 배치된다.The carrier 20 is bolted to the knuckle of the vehicle body, wherein the inner pad plate 40 having the inner pad 41 attached thereto and the outer pad plate 50 having the outer pad 51 attached thereto have a disk 30. It is installed in the longitudinal direction so as to be freely centered. At this time, the other surface of the inner pad plate 40 is disposed in contact with the tip of the piston (13).
그리고 캘리퍼 하우징(10)은 캐리어(20)의 양단부에 가이드로드(60)를 통해 유격가능하게 장착되고, 피스톤(13)이 설치되도록 후방부에 가공된 보어(11)와 아웃터패드플레이트(50)를 감싸도록 전방부에서 하측방향으로 굽어지게 성형된 핑거부(14)를 구비한다. 미설명부호 12는 제동유압이 전달되도록 보어(11)와 연통되게 가공된 유압포트이고, 15는 피스톤(13)을 자체 탄성력으로 복원시키도록 보어(11)의 내주에 설치된 시일이다.In addition, the caliper housing 10 is mounted at both ends of the carrier 20 so as to be freely spaced through the guide rod 60, and the bore 11 and the outer pad plate 50 which are machined at the rear portion so that the piston 13 is installed. It is provided with a finger portion 14 is formed to be bent in the downward direction from the front to surround the. Reference numeral 12 is a hydraulic port machined in communication with the bore 11 so that the braking hydraulic pressure is transmitted, 15 is a seal installed on the inner circumference of the bore 11 to restore the piston 13 to its own elastic force.
피스톤(13)은 보어(11)에 진퇴운동 가능하게 설치되어 마스터실린더(미도시)에서 형성된 제동유압에 의해 작동하는데, 보어(11)는 피스톤(13)의 압력이 패드(41)(51) 중심선(D1)을 기점으로 디스크(30)의 전진회전방향(화살표 C방향) 출구측에 상대적으로 강하게 가해지도록 디스크(30)의 전진회전방향 출구측으로 편심되게 가공된다.The piston 13 is installed in the bore 11 so as to move forward and backward and is operated by the braking hydraulic pressure formed in the master cylinder (not shown), the pressure of the piston 13 is the pad (41) (51) From the center line D1, it is machined eccentrically toward the exit direction of the forward rotation direction of the disk 30 so as to be applied relatively strongly to the exit direction of the disk 30 in the forward rotation direction (arrow C direction).
즉, 도 3에 도시한 바와 같이 보어(11)는 중심선(D2)이 패드(41)(51)의 중심선(D1)을 기점으로 디스크(30) 전진회전방향 출구측으로 "E"의 길이만큼 편심되게 마련되는데, 보어(11)의 편심량(E)은 패드(41)(51)의 초기두께와 마찰계수 등의 인자를 고려하여 산출된 값이다.That is, as shown in FIG. 3, the bore 11 has the center line D2 eccentric by the length of "E" toward the exit direction of the disk 30 in the forward rotation direction starting from the center line D1 of the pads 41 and 51. The eccentricity E of the bore 11 is a value calculated in consideration of factors such as the initial thickness of the pads 41 and 51 and the coefficient of friction.
이러한 보어(11)의 편심량(E)은 패드(41)(51)의 초기두께를 T, 패드(41)(51)의 마찰계수를 F라 할 경우, 다음식으로 표현된다.The eccentricity E of the bore 11 is expressed by the following equation when the initial thickness of the pads 41 and 51 is T and the friction coefficient of the pads 41 and 51 is F.
E = T × FE = T × F
따라서 패드(41)(51)의 초기두께(T)와 마찰계수(F)를 고려하여 보어(11)를 편심되게 가공하면, 패드플레이트(40)(50)를 작동시키는 피스톤(13)의 가압력 역시 디스크(30)의 전진회전방향 출구측으로 편중되지만, 디스크(30)의 회전토크에 의해 실제적으로 디스크(30)와 마찰하는 패드(41)(51) 전체에 균일한 면압력이 형성된다.Therefore, when the bore 11 is eccentrically processed in consideration of the initial thickness T and the friction coefficient F of the pads 41 and 51, the pressing force of the piston 13 for operating the pad plates 40 and 50 is eccentric. Again, the disk 30 is biased toward the exit direction in the forward rotational direction, but a uniform surface pressure is formed on the entirety of the pads 41 and 51 that actually rub against the disk 30 by the rotational torque of the disk 30.
다음에는 이와 같이 구성된 본 발명에 따른 편심 보어(11)가 형성된 캘리퍼 하우징(10)의 작동 및 효과를 설명한다.Next, the operation and effect of the caliper housing 10 in which the eccentric bore 11 according to the present invention configured as described above is formed will be described.
먼저, 자동차의 전진 시 운전자가 브레이크패달(미도시)을 밟으면 마스터실린더에서 제동유압이 형성되고, 이것은 유압포트(12)를 통해 보어(11)내로 전달되어 피스톤(13)이 전진한다.First, when the driver steps on the brake pedal (not shown) when the vehicle moves forward, a braking hydraulic pressure is formed in the master cylinder, which is transmitted into the bore 11 through the hydraulic port 12 so that the piston 13 moves forward.
계속하여 피스톤(13)의 전진으로 인너패드플레이트(40)가 내측으로 밀려 회전하는 디스크(30)와 인너패드(41)가 마찰하고, 아울러 보어(11)에 잔존하는 유압에 의해 캘리퍼 하우징(10)이 피스톤(13)과 반대방향으로 이동함에 따라 핑거부(14)가 아웃터패드플레이트(50)를 밀게됨으로써 아웃터패드(51)가 디스크(30)에 압착되어 제동력이 발휘된다.Subsequently, the inner pad plate 40 is pushed inward by the advance of the piston 13 and the disk 30 and the inner pad 41 are rotated, and the caliper housing 10 is caused by hydraulic pressure remaining in the bore 11. As the) moves in the opposite direction to the piston 13, the finger portion 14 pushes the outer pad plate 50 so that the outer pad 51 is pressed against the disk 30 and the braking force is exerted.
이러한 제동력은 피스톤(13)의 진퇴운동에 의해 발휘되는데, 피스톤(13)이 내장되는 보어(11)가 디스크(30)의 전진회전방향측으로 "E"만큼 편심되게 가공되어 있기 때문에, 피스톤(13)은 인너패드플레이트(40)에 편심압력을 가하게 된다. 즉, 보어(11)의 편심가공으로 인해 피스톤(13) 선단은 인너패드(41)의 중심선(D1)을 기점으로 인너패드플레이트(40)의 디스크(30) 전진회전방향 출구측을 상대적으로 강하게 밀게 된다.This braking force is exerted by the forward and backward motion of the piston 13, and since the bore 11 in which the piston 13 is built is eccentrically processed by " E " toward the forward rotation direction side of the disk 30, the piston 13 ) Exerts an eccentric pressure on the inner pad plate 40. That is, due to the eccentric machining of the bore 11, the end of the piston 13 is relatively strongly at the exit side of the disk 30 in the forward rotation direction of the inner pad plate 40 from the center line D1 of the inner pad 41. Pushed.
따라서 디스크 브레이크의 특성, 즉 디스크(30)의 회전토크에 의해 디스크(30)의 양측면에 가해지는 인너패드(41)와 아웃터패드(51)의 면압력은 자동차의 전진방향에 대해 디스크(30)의 입구측으로 집중되려고 하지만, 인너패드플레이트(40)와 아웃터패드플레이트(50)에 피스톤(13)으로부터 가해지는 압력이 디스크(30) 전진회전방향의 출구측으로 강하게 편심으로 작용함으로써, 실제 제동작용 시 인너패드(41)와 아웃터패드(51)는 전체적으로 디스크(30)의 측면에 균일한 압력으로 마찰하여 제동력이 보다 향상된다. 또한, 인너패드(41)와 아웃터패드(51)의 마모상태가 균일하게 이루어져 이들의 내구성이 향상되며, 제동소음 역시 줄어들게 된다.Therefore, the surface pressure of the inner pad 41 and the outer pad 51 applied to both side surfaces of the disk 30 by the characteristics of the disk brake, that is, the rotational torque of the disk 30, is determined by the disk 30 against the vehicle's forward direction. The pressure applied from the piston 13 to the inner pad plate 40 and the outer pad plate 50 acts strongly eccentrically toward the outlet side of the disk 30 in the forward rotational direction. The inner pad 41 and the outer pad 51 are generally rubbed with a uniform pressure on the side surface of the disk 30 to further improve the braking force. In addition, since the wear state of the inner pad 41 and the outer pad 51 is uniform, their durability is improved, and the braking noise is also reduced.
이상에서 상세히 설명한 바와 같이, 본 발명에 따른 디스크 브레이크의 캘리퍼 하우징에 의하면, 패드의 중심선을 기점으로 피스톤이 진퇴운동 가능하게 설치되는 보어를 디스크의 전진방향측으로 편심되게 가공하여 피스톤의 압력이 전진방향 출구측에 상대적으로 강하게 가해짐으로써, 실제 제동작용 시 패드의 마모상태가 전체적으로 보다 균일하게 이루어져 내구성이 증대되고 제동소음이 감소하여 전체적인 디스크 브레이크의 신뢰성이 보다 향상되는 이점이 있다.As described in detail above, according to the caliper housing of the disc brake according to the present invention, the pressure of the piston is moved forward by processing the bore in which the piston is installed to move forward and backward from the center line of the pad so as to be eccentrically toward the forward direction of the disc. By being applied relatively strongly to the outlet side, the wear state of the pad is more uniform throughout the actual braking action, the durability is increased, the braking noise is reduced, there is an advantage that the reliability of the overall disc brake is more improved.
