Description
본 고안은 차량등 진동이 발생하는 부위에 장착되는 부시에 관한 것으로, 특히 부시의 내부에 개재되는 방진 고무내부에 내장되는 인너링을 개선한 변형 방지용 인너링이 내장된 부시에 관한 것이다.The present invention relates to a bush mounted on a vibration generating part such as a vehicle, and more particularly, to a bush having a built-in strain preventing inner ring having improved inner ring embedded in a dustproof rubber interposed inside the bush.
일반적으로 부시는 차량등 진동을 직, 간접적으로 받는 부위에 장착하여 진동전달의 감쇄와 소음의 감소를 시킬 목적으로 사용한다.In general, the bush is used to directly or indirectly receive vibrations, such as a vehicle, for the purpose of reducing vibration transmission and reducing noise.
상기한 부시의 종래 기술은 도 1에 도시한 바와 같이 아웃 파이프(1)와 인너 파이프(2) 사이에 방진고무(3)를 개재한 구조로서, 방진 고무의 성형시 방진 고무 내부에는 원통형의 인너링(4)을 축삽시켜 인너링을 입설시킨 상태에서 고온의 용융된 방진고무를 부어 냉각시켜 성형하는 것이다.The prior art of the bush has a structure in which the anti-vibration rubber 3 is interposed between the out pipe 1 and the inner pipe 2, as shown in FIG. In the state in which the inner ring is inserted by inserting the ring 4, hot molten dustproof rubber is poured and cooled to be molded.
상기한 종래 부시의 제조시 인너링을 사이에 두고 방진 고무의 냉각시 인너링 외부의 용융고무는 급속히 냉각되는 반면 인너링 내측의 용융고무는 냉각 속도가 더디므로 냉각 속도차에 의한 밀도의 변화가 생겨 인너링의 위치가 셋팅된 위치에서 성형되어 이로 인한 작동 효과상의 변화가 발생하였다.In the manufacture of the conventional bush, the melted rubber outside the inner ring is rapidly cooled while the inner rubber is cooled with the inner ring interposed, while the melted rubber inside the inner ring has a slow cooling rate. Therefore, the inner ring was molded at the set position, thereby causing a change in operating effect.
본 고안은 상기한 점을 감안하여 안출된 것으로서, 본 고안은 부시의 제작시 아웃 파이프와 인너 파이프 사이에 개재되는 인너링의 구조를 개선시켜 방진 고무의 성형시 냉각속도를 일정하게 유지시켜 인너링의 입설 위치가 가변되지 않도록 하는데 본 고안의 목적이 있는 것으로서, 본 고안은 상기 목적을 달성하기 위하여금속재로된 아웃 파이프와 인너 파이프의 사이에 개재되는 인너링에 있어서, 인너링의 외주연에 용융고무의 이동이 자재롭도록 흐름공을 천공하고 상하단에도 흐름홈을 절개한 구조를 갖는 변형 방지용 인너링이 내장된 부시를 제공하려는데 본 고안의 기술적 과제가 있는 것이다.The present invention has been devised in view of the above, the present invention improves the structure of the inner ring interposed between the out pipe and the inner pipe during the manufacture of the bush to maintain a constant cooling rate when forming the dust-proof rubber inner ring The purpose of the present invention is to prevent the installation position of the variable, the present invention is melted on the outer periphery of the inner ring in the inner ring interposed between the outer pipe and the inner pipe made of metal material to achieve the above object There is a technical problem of the present invention to provide a bush with a deformation preventing inner ring having a structure in which a flow hole is drilled so as to move rubber and a flow groove is cut in the upper and lower ends thereof.

이하 본 고안의 일실시예를 첨부된 도면을 참조하여 상세히 살펴본다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 고안인 변형 방지용 인너링이 내장된 부시의 일부 분리 사시도로서, 금속재로된 아웃 파이프(10)와 인너 파이프(20)의 사이에 개재되는 인너링(30)에 있어서,2 is a partially separated perspective view of a bush in which the inner ring for deformation prevention according to the present invention is incorporated, and in the inner ring 30 interposed between the outer pipe 10 and the inner pipe 20 made of metal,
인너링(30)의 외주연에 일측에 소정 간격으로 사각의 흐름공(21)을 천공하고 흐름공의 상하단에도 흐름홈(22)을 절개하되, 인너 파이프와 아웃 파이프속에 용융되어 냉각된 방진고무(40)는 상기 흐름공(21)과 흐름홈(22)을 관통하여 일체로 성형한 구조이다.Perforated rectangular flow holes 21 on one side at predetermined intervals on the outer circumference of the inner ring 30 and cut the flow grooves 22 at the upper and lower ends of the flow holes, but melted and cooled in the inner pipe and the out pipe. 40 is a structure that is integrally molded through the flow hole 21 and the flow groove 22.
상기한 구조를 갖는 본 고안의 작용은 도 3에 도시한 바와 같이 인너 파이프와 아웃 파이프 중앙 소정위치에 인너링을 입설시킨 상태에서, 상부에 고온에서 용융된 용융고무를 쏟아 부어 냉각 성형하는데, 냉각시 흐름공을 통하여 용융고무분자들의 상호 왕래가 빈번하므로 온도차에 의해 개별적인 부분 냉각이 발생되지 않아 부분적 냉각으로 인한 밀도차에 의해 인너링의 입설 위치가 벗어나는 것을 방지 시킬수 있는 것이다.The operation of the present invention having the above-described structure, as shown in Figure 3 in the inner pipe and the out pipe in the state in which the inner ring is placed in a predetermined position, by pouring the molten rubber melted at a high temperature in the upper portion, the cooling molding Since the molten rubber molecules come and go frequently through the time flow hole, the individual partial cooling does not occur due to the temperature difference, thereby preventing the entrance position of the inner ring from the density difference due to the partial cooling.
상기한 구성과 작용을 하는 본 고안은 인너링의 입설시 방진 고무의 냉각시에 부분적 냉각으로 인한 밀도차에 의해 인너링의 입설 위치가 벗어나는 것을 방지 시킬수 있어 부시의 내구성을 향상시키고 불량율을 줄일수 있는 것이다.The present invention having the above-described configuration and function can prevent the entry position of the inner ring out of the position of the inner ring due to the density difference due to the partial cooling during the cooling of the anti-vibration rubber during the installation of the inner ring, thereby improving the durability of the bush and reducing the defective rate. It is.
