본 발명은 수동변속기의 윤활유 드레인 플러그에 관한 것으로서, 특히 수동변속기 내 윤활유를 다중으로 드레인할 수 있는 수동변속기의 윤활유 드레인 플러그에 관한 것이다.The present invention relates to a lubricating oil drain plug of a manual transmission, and more particularly to a lubricating oil drain plug of a manual transmission capable of draining a plurality of lubricating oils in the manual transmission.

일반적으로 수동변속기는 엔진과 구동바퀴 사이에 장착되어 차량의 주행 상태 변화에 따라 엔진의 동력을 변속시킨 후 변속된 엔진의 동력을 구동바퀴에 전달하는 장치로서, 운전자가 차실 내에 구비된 변속레버를 직접 조작함으로써 작동된다.In general, the manual transmission is mounted between the engine and the driving wheel to change the power of the engine according to a change in the driving state of the vehicle, and then transmits the power of the shifted engine to the driving wheel. It is operated by direct operation.

종래 기술에 따른 수동변속기는 엔진의 동력을 변속시키기 위한 동기장치 및 베어링 등의 회전요소를 윤활하고, 고속 회전으로 인한 각 접동부의 마찰 및 열화를 방지토록 내부에 일정 수위까지 윤활유가 충전되어 있다. 따라서, 상기 수동변속기 내 윤활유가 동기장치의 회전시 비산되어 각 회전요소 및 접동부에 자연윤활방식으로 공급되거나 윤활유 펌프에 의해 수동변속기 상부로 압송되어 수동변속기의 상부에서 비산됨으로써 공급된다. The manual transmission according to the prior art lubricates rotating elements such as a synchronous device and a bearing for shifting engine power, and is filled with lubricating oil to a predetermined level to prevent friction and deterioration of each sliding part due to high speed rotation. . Therefore, the lubricating oil in the manual transmission is scattered at the time of rotation of the synchronous device and supplied to each rotating element and the sliding part in a natural lubrication manner, or is pumped to the upper part of the manual transmission by a lubricating oil pump and is supplied by the upper part of the manual transmission.

이러한 수동변속기 내 윤활유는 회전요소 및 접동부의 마찰시 쇳가루 등의 이물질이 혼입되기 때문에 윤활유 수명에 한계가 있어 일정 시간이 지나면 윤활유 속에 혼입된 이물질을 제거하기 위해 드레인(Drain)되어야 한다. 따라서 상기 수동변속기에는 상기 수동변속기 내 윤활유 드레인을 위해 일반 플랜지 볼트 구조의 드레인 플러그가 구비된다.The lubricant in the manual transmission has a limitation in the life of the lubricant due to the mixing of foreign matters such as crushed powder during the friction of the rotating element and the sliding part. Therefore, the lubricant should be drained to remove the foreign matter mixed in the lubricant after a certain time. Accordingly, the manual transmission is provided with a drain plug having a general flange bolt structure for draining lubricant in the manual transmission.

그러나 상기한 바와 같은 종래 기술에 따른 수동변속기의 윤활유 드레인 플러그는 단순히 상기 수동변속기 내 윤활유 드레인을 위해 상기 수동변속기에 형성된 윤활유 드레인 홀을 막고 있는 용도이기 때문에 상기 윤활유 드레인 홀로부터 탈거되면, 상기 수동변속기 내 윤활유가 한꺼번에 쏟아져 작업성이 저하되고, 주변 이 오염되기 쉬운 문제점이 있다.However, since the lubricating oil drain plug of the manual transmission according to the related art as described above is simply used to block the lubricating oil drain hole formed in the manual transmission for lubricating oil drain in the manual transmission, when removed from the lubricating oil drain hole, the manual transmission My lubricant is poured all at once, the workability is lowered, there is a problem that the surroundings tend to be contaminated.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 수동변속기 내 윤활유가 다중으로 드레인될 수 있도록 구비되어 윤활유 드레인 작업성이 향상될 수 있고, 주변 오염을 방지할 수 있는 수동변속기의 윤활유 드레인 플러그를 제공하는데 그 목적이 있다.The present invention has been made to solve the above-mentioned problems of the prior art, it is provided so that the lubricating oil in the manual transmission can be drained in multiple, the lubricating oil drain workability can be improved, and the pollution of the manual transmission can be prevented The object is to provide a lubricant drain plug.

상기한 과제를 해결하기 위한 본 발명에 따른 수동변속기의 윤활유 드레인 플러그는 수동변속기 케이스에 형성된 윤활유 드레인 홀을 개폐할 수 있고, 상기 윤활유 드레인 홀보다 크기가 작은 플러그 홀이 형성된 제1차폐부재와; 상기 플러그 홀을 개폐할 수 있는 제2차폐부재를 포함하여 구성된다.The lubricating oil drain plug of the manual transmission according to the present invention for solving the above problems can open and close the lubricating oil drain hole formed in the manual transmission case, the first shield member having a smaller plug hole than the lubricating oil drain hole; It comprises a second shield member that can open and close the plug hole.

The first shielding member 10 may be provided with a lubricating oil filter 20 so that foreign matter in the lubricating oil in the manual transmission case 2 may be filtered. The lubricant filter 20 has an upper surface open and a circumferential surface is provided in a mesh structure. The lubricating oil filter 20 is provided with a collecting portion 22 which is concave downward so that the filtered foreign matter is easily collected. The collecting unit 22 is provided with a plurality of arranged in the vertical direction so that the foreign matter can be collected in multiple. The collecting part 22 is formed with a second shielding member hole 22A through which the second shielding member 12 penetrates.

상기 제1차폐부재(10)에는 윤활유 속 금속성 이물질 포집이 용이하도록 마그네트(26)가 구비된다. 상기 마그네트(26)는 상기 포집부(22)의 중앙에 위치된다. 상기 마그네트(26)는 상기 제2차폐부재(12)가 관통될 수 있도록 링 구조이다. The first shield member 10 is provided with a magnet 26 to facilitate the collection of metallic foreign matter in the lubricating oil. The magnet 26 is located at the center of the collecting part 22. The magnet 26 has a ring structure to allow the second shield member 12 to pass therethrough.

상기 제2차폐부재(12)는 상기 플러그 홀(10A)에 스크류 체결될 수 있도록 볼 트 구조로 구비된다.The second shield member 12 is provided with a bolt structure to be screwed into the plug hole (10A).

상기와 같이 구성된 본 발명의 동작을 살펴보면 다음과 같다.Looking at the operation of the present invention configured as described above are as follows.

상기 수동변속기 케이스(2)에 장착되어 있을 때에는, 상기 수동변속기 케이스(2) 내 윤활유가 상기 윤활유 필터(20)를 통과하면서 필터링된다. 이 때 상기 윤활유 필터(20)에서 필터링된 이물질은 상기 포집부(22)의 중앙에 포집되고, 특히 금속성 이물질은 상기 마그네트(26)에 부착된다. When attached to the manual transmission case 2, the lubricating oil in the manual transmission case 2 is filtered while passing through the lubricating oil filter 20. At this time, the foreign matter filtered by the lubricating oil filter 20 is collected in the center of the collecting unit 22, and in particular, the metallic foreign matter is attached to the magnet 26.

한편, 상기 수동변속기 케이스(2) 내 윤활유 드레인시 상기 제2차폐부재(12)를 탈거하게 되면, 상기 수동변속기 케이스(2) 내 윤활유가 상기 플러그 홀(10A)을 통해 드레인된다. 이 때 상기 플러그 홀(10A)은 크기가 작은 편이기 때문에 상기 수동변속기 케이스(2) 내 윤활유가 천천히 드레인될 수 있다. 반면 상기 수동변속기 케이스(2) 내 윤활유 드레인시 상기 제1차폐부재(10)를 탈거하게 되면, 상기 수동변속기 케이스(2) 내 윤활유가 상기 윤활유 드레인 홀(2A)을 통해 드레인된다. 이 때 상기 윤활유 드레인 홀(2A)은 크기가 큰 편이기 때문에 상기 수동변속기 케이스(2) 내 윤활유가 신속히 드레인될 수 있다. 따라서 상기 수동변속기 케이스(2) 내 윤활유 드레인시 윤활유 드레인량에 따라 상기 제1,2차폐부재(10)(12) 중 어느 하나가 선택적으로 탈거될 수 있고, 상기 제1,2차폐부재(10)(12)가 차례로 탈거될 수도 있다.On the other hand, when the second shield member 12 is removed when the lubricant is drained in the manual transmission case 2, the lubricant in the manual transmission case 2 is drained through the plug hole 10A. At this time, since the plug hole 10A is small in size, the lubricating oil in the manual transmission case 2 may be slowly drained. On the other hand, when the first shield member 10 is removed when the lubricant is drained in the manual transmission case 2, the lubricant in the manual transmission case 2 is drained through the lubricant drain hole 2A. At this time, since the lubricating oil drain hole 2A is large in size, the lubricating oil in the manual transmission case 2 can be quickly drained. Accordingly, any one of the first and second shielding members 10 and 12 may be selectively removed according to the amount of lubricant drainage when the lubricant is drained in the manual transmission case 2, and the first and second shielding member 10 may be removed. 12 may be removed in turn.

상기와 같이 구성되는 본 발명에 따른 수동변속기의 윤활유 드레인 플러그는 수동변속기 케이스에 형성된 윤활유 드레인 홀을 차폐하는 제1차폐부재와, 상기 제1차폐부재에 형성된 상기 윤활유 드레인 홀보다 작은 크기의 플러그 홀을 차폐하는 제2차폐부재를 포함함으로써, 상기 수동변속기 케이스 내 윤활유가 다중으로 드레인될 수 있어 작업성이 향상될 수 있고, 주변 오염을 방지할 수 있는 이점이 있다.The lubricating oil drain plug of the manual transmission according to the present invention configured as described above includes a first shielding member for shielding a lubricating oil drain hole formed in the manual transmission case, and a plug hole having a smaller size than the lubricating oil drain hole formed in the first shielding member. By including a second shielding member for shielding, the lubricating oil in the manual transmission case can be drained in multiple to improve workability, there is an advantage that can prevent the surrounding pollution.
