본 고안은, 캘리퍼 보디를 미끄럼 운동핀으로 슬라이드시켜서 제동작용을 하는 핀 슬라이드형의 차량용 디스크 브레이크의 캘리퍼 보디에 관한 것이다.The present invention relates to a caliper body of a pin slide type vehicle disc brake which slides a caliper body with a sliding motion pin to perform a braking action.
제5도는, 종래의 핀 슬라이드형 차량용 디스크 브레이크의 1예를 나타내며, 캘리퍼 보디(20)는, 부착아암(21), (21)의 앞끝단에 돌출설치한 각 미끄럼운동핀(22)을, 캘리퍼 브래킷(23)의 캘리퍼 지지아암에 형성한 삽통구멍에 각각 끼워넣고, 디스크 축 방향으로 이동가능하게 지지되어 있다. 부착아암(21), (21)은, 작용부(24)에 형성된 실린더 구멍(25)의 둘레벽(25a)의 양쪽으로 부터 연장시켜서 일체로 형성하고, 또한 디스크 로터(26)의 측면과 평행하도록 형성 되어 있다.5 shows an example of a conventional pin slide type vehicle disc brake, and the caliper body 20 has each sliding pin 22 protruding from the front end of the attachment arms 21 and 21, It is inserted in the insertion hole formed in the caliper support arm of the caliper bracket 23, respectively, and is supported so that a movement to the disk axial direction is possible. The attachment arms 21 and 21 extend integrally from both sides of the circumferential wall 25a of the cylinder hole 25 formed in the acting portion 24 and are integrally formed and parallel to the side surface of the disc rotor 26. It is formed to
그러나, 이러한 종류의 형상에서는, 제동시에 캘리퍼 보디(20)가, 제동반력에 의하여, 디스크 로터 바깥 쪽의 브리지부를 중심으로, 작용부(24)와 반작용부 쪽의 반력동기가 八자 형상으로 벌어지고, 또 이 변형이 부착아암(21)을 통하여, 미끄럼운동핀(22)에 전달된다. 이 때문에, 미끄럼운동핀(22)을 기울게 하여, 캘리퍼 보디(20)의 미끄럼운동성을 나쁘게 한다고 하는 문제가 있다.However, in this type of shape, the caliper body 20 at the time of braking causes the acting portion 24 and the reaction force side of the reaction portion to be in an octagonal shape by the braking reaction centering on the bridge portion outside the disc rotor. This deformation is transmitted to the sliding pin 22 through the attachment arm 21. For this reason, there exists a problem that the sliding pin 22 is inclined and the sliding motion of the caliper body 20 is bad.
또, 실린더 구멍(25)의 둘레(25a)에서는, 부착아암(21)이 일체로 형성되는 것에 의하여, 부착아암 연결부분이 다른 부분의 둘레벽(25a) 보다도 두꺼워지므로, 캘리퍼 보디(20)를 주조할 때에는, 이 부분의 냉각은 다른 부분의 냉각보다 더디며, 특히 둘레벽(25a)의 내벽쪽에서는 기공(gross porosity)이 발생하는 원인으로 되어 있었다.In the circumference 25a of the cylinder hole 25, the attachment arm 21 is integrally formed, so that the attachment arm connecting portion becomes thicker than the circumferential wall 25a of the other portion. At the time of casting, cooling of this part is slower than cooling of other parts, and in particular, it was the cause of generation of pores (gross porosity) on the inner wall side of the peripheral wall 25a.
그래서 본 고안은, 제동반력에 의한 임의로운 운동을 강제로 억제하여, 캘리퍼 보디의 미끄럼운동성을 확보함과 동시에, 실린더 구멍의 두께가 불균일을 적게하고, 주조불량의 발생을 방지할 수 있는 핀 슬라이드형 차량용 디스크 브레이크의 캘리퍼 보디를 제공하는 것을 목적으로 하고 있다.Therefore, the present invention forcibly suppresses arbitrary movement by the braking reaction force, secures sliding motion of the caliper body, reduces the thickness of the cylinder hole, and prevents the occurrence of casting defects. An object of the present invention is to provide a caliper body for a disc brake for a mold vehicle.

[실시예]EXAMPLE
이하, 본 고안의 각 실시예를 도면에 의거하여 설명한다.Hereinafter, each embodiment of the present invention will be described with reference to the drawings.
제1도 내지 제3도는 본 고안의 제1실시예를 나타내며, 디스크 브레이크(1)는, 디스크 로터(2)의 한 쪽에서 차체에 고정설치되는 캐리어 브래킷(3)에, 디스크 로터(2)의 바깥면을 걸친 1쌍의 지지아암(3a), (3a)이 설치되어 있고, 양 지지아암(3a), (3a)의 사이에는, 캘리퍼 보디(4)가, 양측부의 부착아암(4d), (4d)에 돌출설치된 각 미끄럼운동핀(5)을, 지지아암(3a)의 삽통구멍(3b)에 끼워서, 디스크 축 방향으로 이동가능하게 지지되어 있다.1 to 3 show a first embodiment of the present invention, wherein the disc brake 1 is mounted on the carrier bracket 3 fixed to the vehicle body at one side of the disc rotor 2, and thus the disc rotor 2 is removed. A pair of support arms 3a and 3a are provided across the outer surface, and the caliper body 4 is provided between the attachment arms 4d on both sides between the support arms 3a and 3a. Each sliding pin 5 protruding in 4d is inserted into the insertion hole 3b of the support arm 3a, and is supported to be movable in the disc axial direction.
캘리퍼 보디(4)는, 디스크 로터(2)의 양 쪽에 배치되는 작용부(4a) 및 반작용부(4b)와, 이것들을 디스크 로터(2)의 바깥면에 걸쳐서 연결하는 브리지부(4c)로 이루어져 있으며, 작용부(4a)와 반작용부(4b) 사이에는, 1쌍의 마찰패드(6), (6)가 디스크 로터(2)를 끼고 대향 배치되어 있다.The caliper body 4 is provided with the acting part 4a and the reaction part 4b which are arrange | positioned on both sides of the disc rotor 2, and the bridge part 4c which connects these over the outer surface of the disc rotor 2; A pair of friction pads 6 and 6 are disposed to face each other with the disc rotor 2 between the acting portion 4a and the reaction portion 4b.
작용부(4a)에 디스크 로터쪽을 트이게 하여 실린더구멍(4e)으로하고, 이 컵형상의 피스톤(7)이 안 쪽에 끼워진다. 이 실린더 구멍(4e)의 바닥부에 액압실(8)이 구분되어 형성됨과 동시에, 실린더 구멍(4e)의 둘레벽(4h)에는, 상기 부착아암(4d), (4d)이, 양측부로 부터 디스크 로터(2)의 측면과 평행하게 돌출설치되어 있다.The disc rotor side is opened to the acting portion 4a to form the cylinder hole 4e, and the cup-shaped piston 7 is fitted inside. The hydraulic chamber 8 is formed separately at the bottom of the cylinder hole 4e, and the attachment arms 4d and 4d are formed on the circumferential wall 4h of the cylinder hole 4e from both sides. It protrudes in parallel with the side surface of the disc rotor 2.
실린더 구멍(4e)의 저벽(4f)에 형성된 유니온구멍(4g)에는, 도시하지 않은 액공급관이 접속되어 있으며, 유니온 구멍(4g)을 통하여 액압실(8)에 작동액이 공급되면, 이 작동액의 액압에 의하여 피스톤(7)이 디스크로터 방향으로 이동한다.A liquid supply pipe (not shown) is connected to the union hole 4g formed in the bottom wall 4f of the cylinder hole 4e. When the working liquid is supplied to the hydraulic chamber 8 through the union hole 4g, this operation is performed. The piston 7 moves in the disc rotor direction by the hydraulic pressure of the liquid.
각 부착아암(4d)의 기초부에는, 디스크 내면 쪽에 실린더 구멍(4e)의 바깥면을 따라서 각각 오목부(4i)가 형성되어 있고, 또 디스크 바깥쪽에는, 브리지부(4c)로 부터 리브(4j), (4k)가 각각 뻗어나 있다.At the base of each attachment arm 4d, recesses 4i are formed on the inner surface of the disk along the outer surface of the cylinder hole 4e, and on the outer surface of the disk, ribs 4 are formed from the bridge portion 4c. 4j) and 4k extend respectively.
이 리브(4j), (4k)는, 각각 실린더 구멍(4e)을 향하여 형성되어 있고, 리브(4j)는 실린더 구멍(4e)의 둘레벽(4h)에 접하는 위치에 형성되며, 리브(4k)는, 리브(4j)보다 바깥 쪽에, 실린더 구멍(4e)을 향하여 경사지도록 형성되어 있다.The ribs 4j and 4k are formed toward the cylinder holes 4e, respectively, and the ribs 4j are formed at positions contacting the circumferential wall 4h of the cylinder holes 4e, and the ribs 4k are provided. Is formed so as to incline toward the cylinder hole 4e on the outer side of the rib 4j.
리브(4j), (4k)의 틈새에는, 오목부(4m)가 실린더구멍(4e)의 둘레벽(4h)의 바깥면을 따라서 형성되어 있고, 디스크 내면 및 외면 쪽의 오목부(4i), (4m) 형성에 의하여, 둘레벽(4h)의 부착아암 연결부분의 두께를, 다른 부분의 둘레벽(4h)의 두께와 대략 균일하게 되도록 하고 있다.In the gaps between the ribs 4j and 4k, recesses 4m are formed along the outer surface of the circumferential wall 4h of the cylinder hole 4e, and the recesses 4i on the inner and outer surfaces of the disk, By (4m) formation, the thickness of the attachment arm connection part of the circumferential wall 4h is made to be substantially uniform with the thickness of the circumferential wall 4h of another part.
이와같이 형성된 디스크 브레이크(1)는, 액압실(8)에 작동액이 공급되면, 피스톤(7)이 실린더 구멍(4e)을 전진하여, 한 쪽의 마찰패드(6)를 디스크 로터(2)의 한 쪽면에 누르고, 다음에 이 반작용에 의하여 캘리퍼보디(4)가 미끄럼운동핀(5)을 통하여 작용부(4a) 쪽으로 이동하고, 반작용부(4b)가 다른 쪽의 마찰패드(6)를 디스크 로터(2)의 다른 쪽면에 눌러서 제동작용이 이루어진다.When the working fluid is supplied to the hydraulic chamber 8, the disk brake 1 formed as described above moves the cylinder hole 4e to move the friction pad 6 of the disk rotor 2. Pressing on one side, the caliper body 4 is moved to the acting portion 4a through the sliding pin 5 by this reaction, and the reaction portion 4b moves the friction pad 6 on the other side to the disk. Pressing on the other side of the rotor 2 is a braking action.
이 때에, 제동반력에 의하여, 디스크 로터 바깥 쪽의 브리지부(4c)를 중심으로, 작용부(4a)와 반작용부(4b)가 八자형상으로 벌어지려고 한다. 이 작용은, 작용부(4a)로 부터 부착아암(4d)으로 전해지려고 하는데, 이 아암(4d)의 기초부 디스크 내외면에, 오목부(4i), (4m)가 형성되어 있으므로써, 부착아암(4d)이 기울어지기 어렵게 되고, 미끄럼운동핀(5)이 작용부(4a)의 벌어짐의 영향을 받아서 미끄럼운동성이 저하하는 것을 방지할 수 있다. 또, 리브(4j), (4k)가 형성되어 있음으로써, 작용부(4a)의 거동을 억제한다.At this time, by the braking reaction, the acting portion 4a and the reaction portion 4b are about to be formed in an octagonal shape around the bridge portion 4c outside the disc rotor. This action is intended to be transmitted from the acting portion 4a to the attaching arm 4d. The recesses 4i and 4m are formed on the inner and outer surfaces of the base disk of the arm 4d, so The arm 4d is less likely to be inclined, and the sliding pin 5 can be prevented from being affected by the spreading of the acting portion 4a so that the sliding mobility is lowered. Moreover, since the ribs 4j and 4k are formed, the behavior of the acting portion 4a is suppressed.
또한, 오목부(4i), (4m)를 형성함으로써, 실린더(4e)의 두께가 불균일한 것을 적게 할 수 있고, 캘리퍼 보디(4)를 주조할 때에, 실린더 구멍(4e)의 내면쪽 등에 기공이 발생하는 것을 방지할 수 있다. 또, 오목부(4i), (4m)를 형성함으로써, 부착아암(4d)의 두께가 줄어들기 때문에, 캘리퍼 보디(4)의 경량화를 도모할 수 있다.In addition, by forming the recesses 4i and 4m, the thickness of the cylinder 4e can be reduced, and the pores on the inner surface side of the cylinder hole 4e and the like can be reduced when casting the caliper body 4. This can be prevented from occurring. Moreover, since the thickness of the attachment arm 4d is reduced by forming the recessed portions 4i and 4m, the caliper body 4 can be reduced in weight.
제4도는 본 고안의 제2실시예를 나타내는 것으로서, 실린더 구멍(4e)의 둘레벽(4h)에 연결되는 각 부착아암(4d)의 기초부에, 관통구멍(4n)을 실린더 구멍(4e)의 둘레벽(4h)의 외면형상을 따라서 형성하고 있으며, 실린더 구멍(4e)의 둘레벽(4h)의 두께를, 대략 전체 둘레에 걸쳐서 같은 두께로 함과 동시에, 브리지부(4c)로부터 각 부착아암(4d)의 디스크 외면 쪽면으로 늘어나는 보강리브(4p), (4g)를 관통구멍(4n)에 근접시켜서 형성하여, 제동반력에 의한 캘리퍼 보디(4)의 작용을 방지하고 있다.4 shows a second embodiment of the present invention, in which a through hole 4n is provided at the base of each attachment arm 4d connected to the circumferential wall 4h of the cylinder hole 4e. It forms along the outer surface shape of the peripheral wall 4h, and makes the thickness of the peripheral wall 4h of the cylinder hole 4e the same thickness over substantially the whole periphery, and attach | attaches each from the bridge part 4c. The reinforcing ribs 4p and 4g extending to the disk outer surface side of the arm 4d are formed close to the through holes 4n to prevent the action of the caliper body 4 due to the braking reaction force.
또한, 본 고안에서 사용하는 보강리브의 수는, 상술의 각 실시예와 같이 2개에 한정되는 것은 아니고, 필요에 따라서 적절하게 설정하면 좋고, 또 특히 리브를 형성하지 않아도 좋다.In addition, the number of the reinforcement ribs used by this invention is not limited to two like each Example mentioned above, What is necessary is just to set suitably as needed, and it is not necessary to especially form a rib.
또한, 제1실시예에서는, 각 부착아암의 기초부의 디스크 이면쪽과, 디스크 바깥면 쪽의 리부와 리브의 틈새에 오목부가 형성되어 있으나, 본 고안에서는, 특히 리브와 리브의 틈새에 오목부를 형성하지 않아도 지정없다.In addition, in the first embodiment, recesses are formed in the gap between the ribs and ribs on the back surface of the base of each attachment arm and the outer surface of the disk, but in the present invention, recesses are formed especially in the gaps between the ribs and the ribs. You do not have to specify it.
본 고안은 이상과 같이, 실린더 구멍의 둘레벽에 연결되는 부착아암의 기초부에 오목부 또는 관통구멍을 형성하여, 실린더 구멍 둘레벽의 부착 아암 연결부분의 두께를 다른 둘레벽과 대략 같은 두께로 하였으므로, 제동반력에 의한 실린더 구멍의 작용력은, 부착아암에 전하여지기 어려워지고, 미끄럼운동핀이 실린더 구멍의 작용의 영향을 받지 않고, 안정된 미끄럼운동성을 확보할 수 있다. 또한, 실린더 구멍의 두께가 불균일한 것을 적게 할 수 있고, 캘리퍼 보디를 주조할 때에, 실린더 구멍의 내면쪽 등에 기공이 발생하는 것을 방지할 수 있다.The present invention forms a recess or a through hole in the base of the attachment arm connected to the circumferential wall of the cylinder hole as described above, so that the thickness of the attachment arm connection portion of the circumferential wall of the cylinder hole is about the same thickness as the other circumferential wall. As a result, the action force of the cylinder hole due to the braking reaction force is less likely to be transmitted to the attachment arm, and the sliding pin can secure stable sliding motion without being affected by the action of the cylinder hole. In addition, it is possible to reduce the thickness of the cylinder hole with nonuniformity, and to prevent the generation of pores on the inner surface side of the cylinder hole or the like when casting the caliper body.
또, 브리지부로부터 상기 각 부착아암의 디스크 외면 쪽면으로 늘어나는 보강리브를 설치하였으므로, 캘리퍼 보디의 작용부가 보강되어, 제동반력에 의한 실린더 구멍의 움직임을 억제할 수 있다.Further, since a reinforcing rib extending from the bridge portion to the disk outer surface side of each attachment arm is provided, the acting portion of the caliper body is reinforced to suppress the movement of the cylinder hole due to the braking reaction force.
또한, 보강리브와 보강리브 사이에 형성되는 틈새로 부터 부착아암의 기초에 오목부를 형성하고, 상기 실린더 구멍 둘레벽의 부착아암 연결부분의 두께를, 다른 둘레벽과 대략 같은 두께로 하였으므로, 실린더 구멍의 두께를 한층더 같은 두께로 할 수 있고, 캘리퍼 보디의 슬라이드성을 더욱 향상시켜서, 실린더 구멍의 주조불량의 발생을 더욱 방지할 수 있게 된다.Further, a recess is formed in the base of the attachment arm from the gap formed between the reinforcement rib and the reinforcement rib, and the thickness of the attachment arm connection portion of the cylinder hole circumference wall is approximately the same thickness as the other circumference wall. The thickness of can be made even more, and the slidability of the caliper body can be further improved, and the occurrence of casting failure of the cylinder hole can be further prevented.
