본 고안은 자동차용 브레이크에 있어서, 슈우를 라이너에 접탈 작동시키는 휠실런더에 관한 것이다.The present invention relates to a wheel cylinder for engaging a shoe to a liner in an automobile brake.
종래 일반적인 자동차용 브레이크는 제4도에 도시한 바와 같이 라이너(L)에 접탈되는 슈우(S)를 복원 스프링(RS)과 휠실린더(WC)에 의하여 작동하도록 구성된 것으로, 상기 휠실린더(WC)는 제5도와 같이, 브레이크 하우징에 착설되는 실린더 하우징(H) 중안부에 리턴스프링(RS)이 개장된 한쌍의 컵(C)을 삽설하고, 그 양측에 각각 피스톤(P)을 접설하여 그 양단에 연설된 푸시롯드(PR)선단을 슈우(S)의 단부에 연결한 것이었다.Conventional automotive brake is configured to operate the shoe (S) attached to the liner (L) by the restoring spring (RS) and the wheel cylinder (WC), as shown in Figure 4, the wheel cylinder (WC) As shown in Fig. 5, a pair of cups C with return springs RS installed in the central portion of the cylinder housing H mounted on the brake housing is inserted, and the piston P is connected to both sides thereof, respectively. The push rod (PR) tip addressed at the end was connected to the end of the shoe (S).
그러나 종래의 휠실린더는 외부의 이물질 침입과 실린더 내의 오일누설을 방지하기 위하여 중앙에 푸시롯드(PR)가 관통되는 고무부우터(B)를 실린더 하우징(H)의 양단에 감각한 것으로푸시롯드(PR)와 부우터(B)사이의 기밀을 단순히 부우터(B)자체의 탄성력에 의존하였기 때문에 완전한 기밀이 유지되지 않아서 이물질(먼지나 물)이 침입되고 내부 오일이 누설되므로 휠실린더(WC)를 손상시키는 폐단이 있었다.However, in the conventional wheel cylinder, the rubber rod (B) through which the push rod (PR) penetrates in the center to prevent foreign substances from entering the outside and oil leakage in the cylinder is sensed at both ends of the cylinder housing (H). Since the airtight between the PR) and the woofer (B) simply depends on the elastic force of the woofer (B) itself, the complete airtightness is not maintained and foreign matter (dust or water) is infiltrated and the internal oil leaks, so the wheel cylinder (WC) There was a disintegration that hurts.
따라서 본 고안은 이러한 종래의 폐단을 해소하기 위하여 안출된 것으로 이를 첨부 도면에 따라서 상세히 설명하면 다음과 같다.Therefore, the present invention has been devised to solve such a conventional discontinuation, which will be described in detail with reference to the accompanying drawings.
제1도 내지 제3도에 있어서 (1)은 원통형 휠실린더 하우징으로서, 내부 중앙부에는 리턴스프링(2)이 개장되는 한쌍의 컵(3)이 삽설되어 있으며 그 양측에는 각각 피스톤(4)이 접설되어 있고, 피스톤(4)의 외측면에는 푸시롯드(5)가 연설되어 있으며, 하우징(1)의 양단에는 푸시롯드(5)가 관통되는 고무부우터(6)가 감착되어 있다.In Figs. 1 to 3, reference numeral 1 denotes a cylindrical wheel cylinder housing, in which a pair of cups 3 with return springs 2 are inserted in the inner central portion thereof, and pistons 4 are connected to both sides thereof. The push rod 5 is protruded on the outer surface of the piston 4, and the rubber booter 6 through which the push rod 5 penetrates is attached to both ends of the housing 1.
푸시롯드(5)의 중간부에는 요환(7)이 요설되어 있으며, 부우터(6)의 중앙에는 상기 요환(7)에 감착되는 돌환(8)에 의해 관통공(9)이 형성되어 있다.The intermediate part of the push rod 5 is provided with a concave ring 7, and a through hole 9 is formed in the center of the woofer 6 by a projection 8 that is attached to the concave ring 7.
상기 푸시롯드(5)에는 요환(7)의 양측에 각각 반대방향 나사부(10)(10')가 설치되어 있으며, 각 나사부(10)(10')에는 각각 상기 돌환(8)의 양측면(8')을 협지하는 반대방향 나사로된 링너트(11)(11')가 나합되어 있다.The push rods 5 are provided with opposite threaded portions 10, 10 ′, respectively, on both sides of the concave ring 7, and each of the threaded portions 10, 10 ′, both sides 8 of the protrusion 8, respectively. Ring nuts (11) (11 ') with counterscrews sandwiching') are screwed together.
이러한 구성의 본 고안은 실린더(1)의 양단에 부우터(6)를 감착함에 있어서, 푸시롯드(5)의 요환(7)에 부우터(6)의 돌환(8)을 감착하고, 상기 나사부(10)(10')에 각각 링너트(11)(11')를 나합하여 조인 다음 푸시롯드(5)를 돌리면 나사부(10)과 (10' 및 링너트(11)와 (11')는 각각 나선 방향이 반대(즉, 한쪽은 오른나사이고, 다른쪽은 왼나사)이므로 링너트(11)(11')는 서로 접근하면서 돌환(8)의 양측면(8')을 조이게 되는 것이다.According to the present invention of the above configuration, in attaching the woofer 6 to both ends of the cylinder 1, the protrusion 8 of the woofer 6 is attached to the urine 7 of the push rod 5, and Ring nuts 11 and 11 'are screwed into the threaded portions 10 and 10', respectively, and then the push rod 5 is turned to turn the threaded portions 10 and 10 'and ring nuts 11 and 11'. Since the spiral directions are opposite to each other (that is, one side is a right side thread and the other side is a left side thread), the ring nuts 11 and 11 'close to each other and tighten both sides 8' of the turn 8.
따라서, 푸시롯드(5)와 부우터(6)의 관통공(9)사이는 돌환(8)의 양측면(8')과 링너트(11)(11')에 의해 밀폐되며, 외부의 이물질은 1차적으로 외측 링너트(11)와 돌환(8)에 의해 차단되고 내측 링너트(11')와 돌환(8)에 의해 2차적으로 차단되며, 내부 오일은 1차적으로 내측 링너트(11')와 돌환(8)에 의해 차단되고 외측 링너트(11)와 돌환(8)에 차단되므로 이 물질의 침투와 내부 오일의 누설이 확실하게 방지된다.Therefore, the push rod 5 and the through hole 9 of the woofer 6 are sealed by both side surfaces 8 'of the annular ring 8 and the ring nuts 11 and 11', and the foreign matter It is primarily blocked by the outer ring nut 11 and the annulus 8 and is secondarily blocked by the inner ring nut 11 'and the annulus 8, and the inner oil is primarily the inner ring nut 11'. ) And the round ring 8 and the outer ring nut 11 and the round ring 8, thereby preventing the penetration of this material and the leakage of the inner oil.
또한 부우터(6)를 교환할 경우에는 푸시롯드(5)를 반대방향으로 돌리는 것에 의해 링너트(11)(11')를 이완시키므로써 간편하게 분리할 수 있다.In addition, when the woofer 6 is replaced, the ring nuts 11 and 11 ′ can be easily removed by turning the push rod 5 in the opposite direction.
이상과 같이 본 고안에 의하면 푸시롯드와 부우터의 관통공 사이를 내의측 링너트와 돌환에 의해 2중으로 밀폐하는 것이므로 이물질의 침입과 오일의 누설을 확실하게 방지할 수 있는 효과가 있다.As described above, according to the present invention, since the inside of the push rod and the woofer through-hole is double sealed by the inner ring nut and the annular ring, it is possible to reliably prevent the intrusion of foreign substances and the leakage of oil.
