Abstract

PURPOSE: A hydraulic and pneumatic pressure hose of a car is provided to improve reliability between a hydraulic and pneumatic pressure device and a rubber hose by preventing separation of the rubber hose from a protrusion of a metal pipe even though excessive shock and pressure occur. CONSTITUTION: A hydraulic and pneumatic pressure hose of a car includes a hollow and cylindrical rubber hose(16), a jaw(18), and a crack(20). The jaw is formed by a stepped cone of a sectional area from a location separated at a predetermined interval from an end of the hose. The crack is formed in a longitudinal direction from the end of the hose to a start portion of the jaw. The sectional area of the jaw is gradually reduced toward the end of the rubber hose.

Description

자동차의 유,공압 호스{OIL AND AIR PRESSURE HOSE FOR VEHICLE}OIL AND AIR PRESSURE HOSE FOR VEHICLE

본 발명은 자동차의 유/공압 장치들에 연결되어 유/공압을 전달하는 고무호스에 관한 것으로, 특히 유/공압 장치와 고무호스의 연결부에서 충격 압력이 발생하여도 빠지지 않도록 개선한 자동차의 유/공압 고무호스에 관한 것이다.The present invention relates to a rubber hose which is connected to the oil / pneumatic devices of an automobile and transmits oil / pneumatics. Pneumatic rubber hose.

자동차의 유/공압 장치들에서 발생된 유/공압은 고무호스를 통하여 목적하는 곳으로 전달하게 된다.The oil / pneumatics generated from the oil / pneumatic devices of the vehicle are transferred to the desired place through the rubber hose.

상기한 유/공압 장치들은 대부분 금속으로 이루어져 있고, 유/공압 장치들의입/출력부는 금속재의 파이프를 연장 형성하여 고무호스와 연결시킨다.The oil / pneumatic devices are mostly made of metal, and the input / output part of the oil / pneumatic devices extends a metal pipe to connect with the rubber hose.

도 1에 도시된 바와 같이, 종래에는 금속 파이프를 고무호스의 내경에 삽입한다. 즉, 금속 파이프의 일단에 금속 파이프의 지름 보다 크게 돌출부를 형성한다. 상기 돌출부는 끝단으로 갈수록 직경이 점점 감소되어 최종적으로 금속 파이프의 내경과 동일하게 한다.As shown in FIG. 1, a metal pipe is conventionally inserted into an inner diameter of a rubber hose. That is, at one end of the metal pipe, a protrusion is formed larger than the diameter of the metal pipe. The protrusion gradually decreases in diameter toward the end to finally equal the inner diameter of the metal pipe.

상기한 금속 파이프를 고무호스에 억지로 삽입한 다음 고무호스의 외주에 클램프를 체결시킨다.The metal pipe is forcibly inserted into the rubber hose, and then the clamp is fastened to the outer circumference of the rubber hose.

상기한 바와 같이 종래에는 고무호스의 내경면이 평평한 면으로 되어 있어 금속 파이프와 고무호스가 마찰로만 연결이 되어 있는 상태이다. 그래서 클램프를 세게 조이더라도 갑작스런 충격 압력에 의해 빠지는 경우가 자주 발생하고, 특히 ATF 호스, MASTER BAG 진공호스, PCV 호스 같은 경우에는 상당히 치명적이다.As described above, the inner diameter of the rubber hose is a flat surface, and the metal pipe and the rubber hose are connected by friction only. Therefore, even if the clamp is tightened, it is often caused by sudden impact pressure, especially in case of ATF hose, MASTER BAG vacuum hose and PCV hose, which is quite fatal.

상기한 ATF 호스 같은 경우 한 번 빠지면 TM을 교체해야 하는 극단적인 상황에 이르게되며, MASTER BAG 호스의 이탈의 경우에도 브레이크 페달의 답력이 사람의 힘으로는 누를 수 없을 정도에 이르게 되어 안전사고를 일으킬 수 있다.In the case of the above-mentioned ATF hose, once it is pulled out, an extreme situation is required to replace the TM, and even when the MASTER BAG hose is removed, the pedal pedal's pedaling force can not be pressed by human force, which may cause a safety accident. Can be.

상기한 PCV 호스가 이탈할 경우 흡기 매니폴더의 부압이 실린더의 부압보다 커지는 경우가 생겨 흡기 매니폴더로의 BACKFIRE가 생긴다.When the PCV hose is detached, the negative pressure of the intake manifold may be greater than the negative pressure of the cylinder, resulting in a backfire to the intake manifold.

본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로, 고무호스의 내경에 걸림턱을 형성하여 금속 파이프가 고무호스에 체결되면 빠지지 않게 하기 위한 것이다.The present invention is to solve the problems as described above, to form a locking jaw in the inner diameter of the rubber hose so as not to fall out when the metal pipe is fastened to the rubber hose.

상기의 목적을 달성하기 위한 본 발명의 자동차의 유/공압 고무호스는, 중공 원통형의 고무호스가 구비되고, 상기 호스 끝단에서 일정거리 이격된 위치부터 단면적 단차에 의한 걸림턱이 형성되고, 상기 호스 끝단에서 상기 걸림턱의 시작부까지는 결절홈 형태의 크랙이 길이방향으로 형성된 것을 그 특징으로 한다.Hydraulic / pneumatic rubber hose of the vehicle of the present invention for achieving the above object is provided with a hollow cylindrical rubber hose, the locking jaw is formed by the cross-sectional step difference from the predetermined distance from the hose end, the hose From the end to the beginning of the locking jaw is characterized in that the crack in the form of nodular groove is formed in the longitudinal direction.

이하, 첨부된 도면을 참조하여 본 발명의 일 실시예를 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 유/공압호스의 단면도이고, 도 3은 본 발명의 유/공압호스의 사시도이다.2 is a cross-sectional view of the oil / pneumatic hose of the present invention, and FIG. 3 is a perspective view of the oil / pneumatic hose of the present invention.

도 2 내지 도 3에 도시된 바와 같이, 일단에 돌출부(14)가 형성된 금속 파이프(12)와 중공 원통형의 고무호스(16)가 구비된다. 고무호스(16)의 끝단에서 소정거리 이격된 고무호스의 내경에는 고무호스(16)의 중심방향으로 돌출된 걸림턱(18)이 고무호스의 내경면을 따라 형성된다.As shown in FIGS. 2 to 3, a metal pipe 12 having a protrusion 14 formed at one end thereof and a hollow cylindrical rubber hose 16 are provided. In the inner diameter of the rubber hose spaced a predetermined distance from the end of the rubber hose 16, a locking projection 18 protruding toward the center of the rubber hose 16 is formed along the inner diameter surface of the rubber hose.

걸림턱과 고무호스의 거리를 (D) 라고 하면, 걸림턱(18)의 끝단에서 고무호스(16)의 끝단으로 가면서 단면적을 점점 축소시켜 1/2(D) 부근에서는 고무호스(16)의 내경과 동일하게 한다.When the distance between the locking jaw and the rubber hose is (D), the cross-sectional area is gradually reduced while going from the end of the locking jaw 18 to the end of the rubber hose 16, so that the rubber hose 16 Same as the inner diameter.

상기에서 걸림턱(18)이 고무호스(16)의 끝단으로 가면서 너무 급격하게 감소되면 금속 파이프(12)가 삽입될 때에 걸려서 삽입 작업이 어려워진다.If the locking step 18 is too sharply reduced to the end of the rubber hose 16 when the metal pipe 12 is inserted, it becomes difficult to insert the work.

고무호스(16)에는 도 3에 도시된 바와 같이, 고무호스(16)의 끝단에서 걸림턱(18)의 시작부까지 직선형의 크랙(20)을 형성한다.As shown in FIG. 3, the rubber hose 16 forms a straight crack 20 from the end of the rubber hose 16 to the start of the locking jaw 18.

상기 크랙(20)은 고무호스(16)의 내경보다 큰 직경의 금속 파이프(12)의 돌출부(14)가 삽입될 때에 용이하게 삽입될 수 있도록 하기 위한 것이며, 상기 크랙(20)의 끝에는 응력 집중을 방지하기 위하여 원형의 홀 형태로 이루어진다.The crack 20 is to be easily inserted when the protrusion 14 of the metal pipe 12 of a diameter larger than the inner diameter of the rubber hose 16 is inserted, the stress concentration at the end of the crack 20 In order to prevent the circular hole is made.

상기와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

금속 파이프(12)의 돌출부(14)를 고무호스(16)의 내경으로 밀어 넣는다. 돌출부(14)가 고무호스(16)의 끝단에 걸리면 크랙(20)을 중심으로 고무호스(16)가 벌려지면서 걸림턱(18)의 시작부까지는 자연스럽게 삽입된다. 돌출부(14)를 계속 밀어 넣어 걸림턱(18)의 시작부에 걸리면 이때부터 강제로 고무호스(16)내로 삽입한다.The protrusion 14 of the metal pipe 12 is pushed into the inner diameter of the rubber hose 16. When the protrusion 14 is caught by the end of the rubber hose 16, the rubber hose 16 is opened about the crack 20 and naturally inserted to the start of the locking jaw 18. When the projection 14 is continuously pushed into the start of the locking jaw 18, it is forcibly inserted into the rubber hose 16 from this time.

돌출부(14)가 걸림턱(18)을 지나 고무호스(16)의 내부로 완전히 삽입되면 돌출부(14)의 끝과 걸림턱(18)을 일치시킨 후 고무호스(16)의 외주에서 클램프(22)로 조인다.When the protruding portion 14 is completely inserted into the rubber hose 16 through the catching jaw 18, the end of the protruding portion 14 coincides with the catching jaw 18, and then the clamp 22 is formed at the outer circumference of the rubber hose 16. Tighten

상기한 본 발명에 따르면 유/공압 장치로부터 과도한 충격 압력이 발생하더라도 금속 파이프(12)의 돌출부(14)가 고무호스(16)의 걸림턱(18)에 걸려서 빠지지 않으므로 유/공압 장치와 고무호스의 연결부간에 신뢰성이 향상된다.According to the present invention described above, even if excessive impact pressure is generated from the oil / pneumatic device, the protrusion 14 of the metal pipe 12 is not caught by the catching jaw 18 of the rubber hose 16, so the oil / pneumatic device and the rubber hose Reliability is improved between the connections of

전술한 바와 같이 본 발명의 유/공압 고무호스에는 고무호스의 내경을 따라 걸림턱이 형성되고, 이 걸림턱에 금속 파이프의 돌출부가 결합되어 걸림으로서 결합부에 과도한 충격 압력이 발생하여도 고무호스가 금속 파이프의 돌출부에서 빠지지 않게 된다. 따라서 자동차의 유/공압 장치와 결합되는 고무호스간에 신뢰성이향상된다.As described above, in the hydraulic / pneumatic rubber hose of the present invention, a locking jaw is formed along the inner diameter of the rubber hose, and the protrusion of the metal pipe is coupled to the locking jaw so that even if excessive impact pressure occurs in the coupling portion, the rubber hose Does not fall out of the protrusion of the metal pipe. Therefore, the reliability is improved between the rubber hose coupled to the hydraulic / pneumatic device of the vehicle.
