본 고안은 씰링기능이 향상된 캘리퍼브레이크용 슬라이딩핀 부트에 관한 것으로서 더욱 상세하게는 기밀성이 향상되도록 부트의 구조를 개선한 것이다.The present invention relates to a sliding pin boot for caliper brake with improved sealing function, and more particularly, to improve the structure of the boot to improve the airtightness.
캘리퍼브레이크는 캘리퍼하우징에 대하여 상대적으로 이동하는 캐리어를 구비하고, 상기 캘리퍼하우징에는 실린더, 피스톤 및 패드를 구비하고 패드와 패드사이에는 구동축의 회전을 전달받아 구동하는 디스크가 마련되는 구성이다.The caliper brake has a carrier which moves relatively to the caliper housing, and the caliper housing includes a cylinder, a piston and a pad, and a disk for driving the rotation of the drive shaft between the pad and the pad.
상기와 같은 캘리퍼브레이크의 작동은 유압연결부를 통하여 압력이 높은상태로 유입되는 오일이 피스톤을 신장시키고, 상기 피스톤은 고무씰을 가지고 캐리어에 지지된 패드를 실린더 내에서 회전하는 디스크를 잡아주어 제동시키는 것이다.The operation of the caliper brake is such that the oil flowing in the state of high pressure through the hydraulic connection extends the piston, and the piston has a rubber seal to hold the disk rotating in the cylinder and brake the disk. will be.
상기 캘리퍼브레이크의 캐리어에는 슬라이딩핀을 삽입하여 패드를 압착하여주는 피스톤작동에 대한 반력으로 작동하는 캘리퍼하우징과 캐리어를 슬라이딩이동시켜주는 가이드 역할을 하며, 캘리퍼브레이크의 캐리어에 형성된 핀공에 장입된 슬라이딩핀의 선단부에 형성된 결합공을 통하여 캘리퍼하우징과 고정볼트로 결합되며, 이 부위에 개입되는 것이 슬라이딩핀 부트이다.The sliding pin is inserted into the carrier of the caliper brake and serves as a guide for sliding the carrier and the caliper housing which acts as a reaction to the piston acting to press the pad to squeeze the pad. It is coupled to the caliper housing and the fixing bolt through the coupling hole formed at the front end of the sliding pin boot.
상기 슬라이딩핀 부트는 핀공과 슬라이딩핀의 외면에 형성되는 그리스보지(保持)부에 윤활을 목적으로 밀봉되는 그리스의 유출을 방지하는 목적으로 사용되며, 이외에 수분의 침투나 기타 이물질이 침투하는 것을 방지하여주는 역할을 동시에 수행하는 것이다.The sliding pin boot is used to prevent the outflow of grease, which is sealed for lubrication to the grease retaining portion formed on the outer surface of the pin hole and the sliding pin, and also prevents penetration of moisture or other foreign substances. It is to perform the role at the same time.
이러한 슬라이딩핀 부트(1)의 종래 기술이 제 1 도에 도시되어 있으며 이를 살펴보면, 슬라이딩핀과 결합되는 부위의 외측에는 캐리어의 선단부와 연접할 수 있도록 하여 수분 및 기타 이물질의 침투를 막기위한 돌기(2)가 돌출되어있도 하우징과 결합되는 부위에는 별다른 강구수단이 없었다.The prior art of such a sliding pin boot (1) is shown in Figure 1, and looking at it, the projections for preventing the ingress of moisture and other foreign matter to be connected to the front end of the carrier on the outside of the portion coupled to the sliding pin ( Even though 2) was protruding, there were no steel balls at the part where the housing was combined.
이러한 관계로 잦은 작동이 일어날 경우 초기상태에 발생하던 씰링기능이 상실되어 수분이나 기타 이물질이 슬라이딩핀 내부로 유입되는 경우가 발생하게된다.Due to this relationship, frequent operation occurs and the sealing function that occurred in the initial state is lost, and water or other foreign substances are introduced into the sliding pin.
이러한 경우에는 슬라이딩핀이 원활한 작동을 기대할 수 없기 때문에 실질적인 제동이 이루어지지 않게되는 것이다.In this case, since the sliding pin cannot be expected to operate smoothly, the actual braking is not performed.
특히, 캐리어 부위에 형성되는 돌기(2)는 슬라이딩핀의 축중심에 대하여 직각으로 형성되어 있으므로 캐리어의 선단부와 단순히 연접되는 형상이기 때문에 충분한 눌림에 의한 기밀성이 유지되지 않기 때문에 시간이 지나면서 캐리어의 선단부와 이격율이 높이 수분 및 기타 이물질의 침투가 가장 우려되는 부분이다.In particular, since the protrusions 2 formed on the carrier portion are formed at right angles to the axial center of the sliding pin, they are simply connected to the front end of the carrier, so that airtightness due to sufficient pressing is not maintained. The separation rate from the tip is high, so the penetration of moisture and other foreign matter is the most concerned part.
이에 본 고안에서는 상기한 문제점들을 해결하기 위하여 안출이 된 것으로서 캐리어의 선단부와 연접하는 부위의 돌기형상을 변경하여 충분함 눌림효과를 얻을 수 있도록 함은 물론, 하우징과의 연접부위에도 별도의 돌기를 더 형성하여 기밀성을 향상시켜 수분이나 기타 이물질의 침투가 방지되도록 한 것이 특징이다.Therefore, in the present invention, as a solution to solve the problems described above, by changing the shape of the projection of the portion that is in contact with the front end of the carrier to obtain a sufficient depressing effect, as well as a separate projection in the connection with the housing It is further formed to improve airtightness to prevent penetration of moisture or other foreign matter.
이하 첨부되는 도면과 관련하여 본 고안의 구성과 작용 및 효과에 대하여 설명을 하면 다음과 같다.Hereinafter, the configuration, operation and effects of the present invention will be described with reference to the accompanying drawings.
제 2 도는 본 고안의 기술이 적용된 슬라이딩핀 부트의 단면도, 제 3 도는 본 고안의 적용상태를 도시한 일부 단면도, 제 4 도는 본 고안의 부트가 적용된 캘리퍼브레이크의 사시도로서 함께 설명을 한다.2 is a cross-sectional view of a sliding pin boot to which the technique of the present invention is applied, FIG. 3 is a partial cross-sectional view showing an application state of the present invention, and FIG. 4 is a perspective view of a caliper brake to which the boot of the present invention is applied.
캘리퍼브레이크(31)에서 패드를 압착하여주는 피스톤작동에 대한 반력으로 작동하는 캘리퍼하우징(14)과 캐리어(13)를 슬라이딩 이동시켜주는 가이핀인 슬라이딩핀(30) 내에 밀봉되는 그리스의 유출방지와 함께 기타 수분과 이물질의 유입방지를 위하여 캐리어의 선단부와 캘리퍼하우징의 후단부에 개입되는 슬라이딩핀 부트를 구성함에 있어서;Prevents the leakage of grease sealed in the caliper housing 14 and the sliding pin 30, which is a guiding pin for sliding the carrier 13, in response to the piston acting to press the pad in the caliper brake 31 and In combination with the front end of the carrier and the rear end of the caliper housing in order to prevent the ingress of other moisture and foreign matters;
상기 슬라이딩핀 부트(10)의 양측에는 슬라이딩핀 부트(10)의 중심에 대한 외측방향으로 씰링용 돌기(11,12)를 형성하여 조립시 상기 돌기(11,12)가 캐리어(13)의 선단과 캘리퍼하우징(14)의 후단부에 의하여 눌림현상과 눌림에 대한 지지력이 일어나 기밀성이 향상되도록 한 것이다.Sealing protrusions 11 and 12 are formed on both sides of the sliding pin boot 10 in the outward direction with respect to the center of the sliding pin boot 10 so that the protrusions 11 and 12 are at the tip of the carrier 13 during assembly. And by the rear end of the caliper housing 14, the pressing phenomenon and the support force for the pressing occurs to improve the airtightness.
상기 캐리어(13)의 선단부와 연접하는 부위에 형성되는 돌기(11)는 캐리어(13) 방향으로 약 20 - 25。의 기울기를 가지게 형성하고, 돌기(11) 상단면의 폭(15)은 1 - 2 ㎜정도로 하는 것이 캐리어(13)의 선단부에 의하여 직접적인 눌림현상을 받도록 한 것이다.The protrusion 11 formed at a portion of the carrier 13 that is in contact with the distal end portion of the carrier 13 is formed to have an inclination of about 20-25 ° toward the carrier 13, and the width 15 of the top surface of the protrusion 11 is 1. 2 mm is to be subjected to direct pressing by the tip of the carrier (13).
상기 돌기(11)의 하단부와 부트(10)와 연접되는 부위인 곡면부(16)의 반경(R)은 0.5 - 1㎜되게 하는 것이 캐리어(13)에 의하여 눌림이 일어나는 돌기(11)에 적절한 탄성을 부여할 수 있다.The radius R of the curved surface portion 16, which is a portion which is in contact with the lower end portion of the protrusion 11 and the boot 10, is 0.5 to 1 mm so that it is suitable for the protrusion 11 to be pressed by the carrier 13. Elasticity can be given.
상기 캘리퍼하우징(14)과 연접되는 부위에 형성되는 돌기(12)는 환형상의 테로 형성하는 것이 캘리퍼하우징(14)과 연접되어 눌림에 대한 지지력을 높일 수 있으며, 돌기(12)의 폭(20)은 1.0 - 1.5㎜정도로 하고 돌기(12)의 상단부 곡률부(21)의 반경(r)은 1.0 - 1.5㎜로 하는 것이 바람직 하다.The protrusion 12 formed at the portion that is in contact with the caliper housing 14 may be formed in an annular frame to be connected to the caliper housing 14 to increase the bearing capacity for pressing, and the width 20 of the protrusion 12 may be increased. Is 1.0-1.5 mm and the radius r of the upper end curvature 21 of the projection 12 is preferably 1.0-1.5 mm.
상기와 같이 구성된 본 고안의 슬라이딩핀 부트(10)를 캐리어(13)와 캘리퍼하우징(14)상간에 개입시킬 경우에는 캐리어(13)와 연접되는 부위에 경사지게 형성된 돌기(11)는 조립시 캐리어(13)의 선단부에 의하여 강한 눌림을 닫게되고, 상기 눌림부위(P)와 캐리어(13)상간에는 상당한 기밀성이 발생하게 되므로서 씰링이 유지되는 것이다.When the sliding pin boot 10 of the present invention configured as described above is interposed between the carrier 13 and the caliper housing 14, the protrusion 11 formed to be inclined at a portion connected to the carrier 13 is a carrier ( A strong pressing is closed by the tip of 13, and a significant airtightness is generated between the pressing portion P and the carrier 13 so that the sealing is maintained.
즉, 상기 돌기(11)가 캐리어(13)와 조립되면서 강한 밀착력을 갖게되므로서 수분이나 기타 이물질이 슬라이딩핀(30) 내로 유입되는 것을 방지하게 되는 것이다.That is, as the protrusion 11 is assembled with the carrier 13, it has strong adhesion, thereby preventing moisture or other foreign matter from entering into the sliding pin 30.
그리고, 상기 캘리퍼하우징(14)과 연접하는 부위에 형성되는 돌기(12)는 부트(10)의 단부가 캘리퍼하우징(14)과의 조립시 캘리퍼하우징(14)에 의한 눌림발생에 대한 지지력을 향상시켜주는 역할을 수행하여 쉽게 눌림에 의하여 변형이 일어나거나 지지력이 약화되는 것을 방지하여 주게된다.In addition, the protrusion 12 formed at a portion in contact with the caliper housing 14 improves the bearing force against the occurrence of pressing by the caliper housing 14 when the end of the boot 10 is assembled with the caliper housing 14. It serves to prevent deformation or weakening of bearing capacity by easy pressing.
그러므로, 이 부위에도 항상 긴장감이 있는 상태를 유지할 수 있게되므로 수분과 이물질이 슬라이딩핀(30)내로 유입되는 것을 방지하게 되는 것이다.Therefore, it is possible to maintain a state of tension at all times even in this part is to prevent water and foreign matter from entering into the sliding pin (30).
이상과 같은 본 고안은 부트조립시 캐리어와 캘리퍼하우징산간의 긴밀한 밀착력을 제공하고 이에 대한 지지력을 보강함으로서 기밀성이 향상되어 슬라이딩핀내로 수분이나 기타 이물질의 유입을 방지하여 원활한 작동성을 제공하여 캘리퍼브레이크의 성능을 향상시킬 수 있는 효과를 가진다.The present invention as described above provides a close adhesion between the carrier and the caliper housing during boot assembly and reinforces the supporting force to improve airtightness, thereby preventing the inflow of moisture or other foreign substances into the sliding pin, thereby providing smooth operability. Has the effect of improving the performance.
