Description

오일팬의 드레인 밸브{Drain valve of oil pan}Drain valve of oil pan

본 발명은 오일팬의 드레인 밸브에 관한 것으로, 보다 상세하게는 볼트형의 플러그 형상을 변경하여 오일팬의 내의 금속찌거기를 제거하는데 오일을 배출할 필요가 없으며, 이를 실현하기 위한 구성부품의 수가 적어 제작비용도 절감되는 오일팬의 드레인 밸브에 관한 것이다.The present invention relates to a drain valve of an oil pan, and more particularly, it is not necessary to discharge oil to remove metal residues in the oil pan by changing a bolt-shaped plug shape, and the number of components for realizing this is small. It relates to a drain valve of an oil pan that also reduces manufacturing costs.

일반적으로 오일팬은 차량의 엔진 하측에 취부되어 엔진 및 변속기의 운전 중 기계적인 마찰에 의해 발생되는 금속찌꺼기 를 엔진오일(또는 트랜스 밋션오일)과 함께 회수하는 것으로, 도 4에는 일반적인 오일팬의 일예를 보인 단면도가 도시되어 있다.In general, the oil pan is installed under the engine of the vehicle to recover metal residues generated by mechanical friction during operation of the engine and the transmission together with the engine oil (or the transmission oil). A cross-sectional view is shown.

즉, 오일팬(10)은 그 외형을 형성하는 용기형상의 저유탱크(11)와, 상기 저유탱크(11)의 하방에 구비된 배유구(12) 및 그 배유구(12)에 대해 나사 결합되는 볼트형상의 플러그(15)고 구비된다.That is, the oil pan 10 is screwed to the container-shaped oil storage tank 11 forming the outer shape, the drain port 12 provided below the oil storage tank 11, and the drain port 12 thereof. The bolt-shaped plug 15 is provided.

상기 플러그(15)는 몸체의 상부가 자석으로 형성되어 있다.The plug 15 is formed of a magnet on the upper portion of the body.

즉, 엔진이 운전하게 되면 엔진에서 발생된 동력에 의해 저유탱크(11)로부터 펌핑된 오일이 소정의 유로를 통하여 순화하게 되고, 또 기계적인 마찰 등에 의해 발생된 금속찌꺼기 등은 상기와 같이 오일이 순환되는 동안에 오일과 함께 저유탱크(11)의 내측으로 회수된다.That is, when the engine is operated, the oil pumped from the oil storage tank 11 is purified through a predetermined flow path by the power generated by the engine, and the metal residue generated by the mechanical friction or the like is oil as described above. The oil is withdrawn into the oil storage tank 11 while being circulated.

또, 상기와 같이 저유탱크(11)의 내측으로 회수된 오일에 함유된 금속찌꺼기들은 자석으로 구비된 플러그(15)의 몸체에 달라붙게 된다.In addition, the metal residues contained in the oil recovered into the oil storage tank 11 as described above are attached to the body of the plug 15 provided with a magnet.

따라서, 작업자는 플러그(15)를 바디로부터 분리한 후 오일을 교환하며 플러그(15)에 달라붙은 금속찌꺼기를 제거하게 된다.Therefore, the operator separates the plug 15 from the body and then exchanges oil to remove the metal residue stuck to the plug 15.

그러나 상기와 같은 일반적인 오일팬에 있어서는 다음과 같은 문제점이 있었다.However, in the general oil pan as described above, there were the following problems.

즉, 프러그(15)에 달라붙은 금속찌꺼기를 제거하기 위해서는 저유탱크(11)로부터 플러그(15)를 분리해야 하는데, 상기와 같이 저유탱크(11)로부터 플러그(15)를 분리하게 되면 그 내측에 저유된 오일을 전부 드레인할 수밖에 없는 문제점이 있었다.That is, in order to remove the metal residue stuck to the plug 15, it is necessary to remove the plug 15 from the oil storage tank 11, and when the plug 15 is removed from the oil storage tank 11 as described above, There was a problem that can drain all the stored oil.

그래서 상기와 같은 문제점을 해결하고자 출원된 기술이 대한민국 특허공개공보번호 특2000-0038550에 공개되어 있다. 도 5는 상기 공개공보에 공개된 기술을 도시한 것으로, 오일팬(10)의 하부 내측면에 제1플러그(40)를 우선 형성하고, 이 제1플러그(40)의 내부공간에 스프링(41)에 의해 탄력지지되는 차단판(42)을 형성하고, 상단이 자석으로 형성된 제2플러그(43)를 배유구(44)에 체결하도록 구성되어 있다.Therefore, the technology applied to solve the above problems is disclosed in Korean Patent Laid-Open No. 2000-0038550. FIG. 5 illustrates a technique disclosed in the above publication, in which a first plug 40 is first formed on a lower inner surface of the oil pan 10, and a spring 41 is formed in an inner space of the first plug 40. And a blocking plate 42 which is elastically supported by (), and is configured to fasten the second plug 43 formed of a magnet to the drain hole 44.

하지만 상기한 기술을 실시하려면 도면에서도 알 수 있듯이 제1플러그 및 제2플러그, 스프링, 차단판 등 상당히 많은 부품이 필요하게 되어 제작비용이 많이 들게 되는 문제점이 있었다.However, in order to implement the above technology, as shown in the drawing, there is a problem in that a large number of parts, such as a first plug and a second plug, a spring, a blocking plate, and the like, require a lot of manufacturing costs.

따라서 본 발명은 상기한 문제점을 해결하고자 안출된 것으로서, 보다 상세하게는 볼트형의 플러그 형상을 변경하여 오일팬의 내의 금속찌거기를 제거하는데 오일을 배출할 필요가 없으며, 이를 실현하기 위한 구성부품의 수가 적어 제작비용도 절감되는 오일팬의 드레인 밸브를 제공하는 데 목적이 있다.Therefore, the present invention has been made to solve the above problems, more specifically, it is not necessary to discharge the oil to remove the metal residues in the oil pan by changing the shape of the bolt-shaped plug, of the component for realizing this Its purpose is to provide an oil pan drain valve that reduces the number and reduces manufacturing costs.

도면 중에 표시된 도면부호 20은 오일이 저장되는 오일팬이며, 도면부호 30은 상기한 오일팬의 오일을 배출하기 위한 드레인 밸브이다.Reference numeral 20 denoted in the drawings is an oil pan in which oil is stored, and reference numeral 30 is a drain valve for discharging oil of the oil pan.

상기한 오일팬(20)은 종래와 마찬가지로 하부에 배출공(22)이 형성된 저유탱크(21)와, 상기 배출공(22)에는 오일을 교환하는 경우에 기존의 오일을 제거하기 위한 드레인 밸브(30)로 구성된다.The oil pan 20 is a storage tank 21 having a discharge hole 22 formed at a lower portion of the oil pan 20, and a drain valve for removing existing oil when the oil is exchanged in the discharge hole 22 ( 30).

상기한 드레인 밸브(30)는 크게 저유탱크(21)의 하부에 고정형성되는너트(31)부와, 너트(31)부에 채워져 배출공(22)을 차단하는 볼트(34)부로 구성된다.The drain valve 30 is largely composed of a nut 31 portion fixed to the lower portion of the oil storage tank 21, and a bolt 34 portion filled in the nut 31 to block the discharge hole 22.

상기 너트(31)의 내주연에는 암나사부(32)가 형성되어 있으며, 배출공(22)의 상부로 그 하면이 고정형성된다.An internal thread portion 32 is formed at an inner circumference of the nut 31, and a lower surface thereof is fixed to an upper portion of the discharge hole 22.

그리고 상기 볼트(34)는 상단나사부(35)와 하단나사부(36)로 2단으로 구성되는데, 상기 상단나사부(35)와 하단나사부(36) 사이에는 상기 나사부(35,36)의 외경보다 가는 환형의 자석부(37)이 형성된다.And the bolt 34 is composed of two stages, the upper screw section 35 and the lower screw section 36, between the upper screw section 35 and the lower screw section 36 is thinner than the outer diameter of the screw section (35, 36) An annular magnet portion 37 is formed.

이 자석부(37)의 길이(B)는 상기 너트(31)의 높이(D)보다 작게 형성된다. 참고로 상단나사부의 길이를 A라 하고, 하단나사부의 길이를 B라 하였을 경우에 너트(31)의 바람직한 길이(D)는 아래식과 같다.The length B of the magnet portion 37 is formed smaller than the height D of the nut 31. For reference, when the length of the upper screw portion is A, and the length of the lower screw portion B is the preferred length (D) of the nut 31 is as follows.

D ≥ 0.5C+0.5A+BD ≥ 0.5C + 0.5A + B

이상과 같이 구성되는 볼트(34)는 평상시 배출공(22)을 통과하여 도 2와 같이 하단나사부(36)가 너트(31)에 체결되는데, 이때 상단나사부(35)와 자석부(37)는 너트(31)보다 돌출된 상태로 오일이 저장된다.The bolt 34 is configured as described above is usually passed through the discharge hole 22, the lower screw portion 36 is fastened to the nut 31 as shown in Figure 2, wherein the upper screw portion 35 and the magnet portion 37 The oil is stored in a protruding state than the nut 31.

따라서 오일팬(20) 내에 저장된 오일에 포함된 금속찌꺼기(S)는 상기한 자석부(37)에 달라붙게 된다.Therefore, the metal dregs S included in the oil stored in the oil pan 20 are attached to the magnet part 37.

작업자가 볼트(34)에 달라붙어 있는 금속찌꺼기(S)를 제거하기 위해서는 상기 볼트(34)를 일정구간 풀리는 방향으로 돌려 자석부(37)가 저유탱크(21)의 외측으로 노출될 수 있도록 하므로서 상단나사부(35)가 너트(31)에 체결되도록 한다.In order for the worker to remove the metal residue S stuck to the bolt 34, the magnet 34 is exposed to the outside of the oil storage tank 21 by turning the bolt 34 in a direction in which the bolt 34 is released. The upper screw portion 35 is fastened to the nut 31.

자석부(37)가 저유탱크(21) 밖으로 노출이 되면 볼트(34)를 푸는 작업을 멈추고 에어건을 이용하여 상기 자석부(37)에 강한 바람을 가하게 되면 자석부(37)에 붙어 있는 금속찌꺼기가 떨어지게 된다.When the magnet part 37 is exposed outside the oil storage tank 21, the work of loosening the bolt 34 is stopped, and when a strong wind is applied to the magnet part 37 by using an air gun, the metal dregs attached to the magnet part 37. Will fall.

자속부(37)의 오일찌꺼기를 완전히 제거한 다음에는 볼트(34)를 다시 반대방향으로 조여 하단나사부(36)가 너트(31)에 체결되도록 한다.After removing the oil residue of the magnetic flux part 37 completely, tighten the bolt 34 again in the opposite direction so that the lower screw part 36 is fastened to the nut 31.

이상과 같이 구성되는 드레인 밸브(30)는 오일팬(20) 내의 금속찌꺼기를 제거하기 위해서 오일팬 내의 오일을 완전히 비우지 않아도 되는 장점이 있다.The drain valve 30 configured as described above has an advantage that the oil in the oil pan does not need to be completely emptied in order to remove metal residues in the oil pan 20.

상기와 같이 구성되는 본 발명은 오일팬 내의 금속찌꺼기를 제거하기 위해서 오일팬 내의 오일을 완전히 비우지 않아도 되는 장점이 있을 뿐만 아니라, 종래 기술에 비해 부품수가 월등히 감소하게 되므로서 조립공정이 단순화되고 제작원가가 절감되는 커다란 장점이 있는 것이다.The present invention configured as described above not only has the advantage of not completely emptying the oil in the oil pan in order to remove metal residues in the oil pan, as well as the number of parts is greatly reduced compared to the prior art, the assembly process is simplified and production cost There is a huge advantage that is saved.
