본 고안은 자동차에 장착되는 오토매틱 트랜스미션의 에어배출용 캡에 관한 것이며, 더욱 상세하게는 체적이 작은 캡이 내면에 나선형의 통기로를 형성하여 에어배출이 자유로운 반면에 이물질 유입의 차단효과가 뛰어나고, 조립이 용이함은 물론 제작단가를 저렴하게한 에어배출용 캡에 관한 것이다.The present invention relates to an air discharge cap of an automatic transmission mounted on an automobile, and more specifically, a small volume cap forms a spiral vent on the inner surface to free air discharge, while having excellent blocking effect of foreign matter inflow. Easy to assemble, as well as the manufacturing cost of the air discharge cap relates to.

이제까지 사용되고 있는 에어배출수단으로는 제 3 도에 나타낸 바와같이, 오토매틱 트랜스미션(1) 일측의 출구가 상방을 향하는 에어배출관(2) 상단 확개부(3)에 신축성을 갖는 역 U 자형의 길다란 호스(4)를 끼움식으로 고정하고, 반대쪽 배출단 내부에는 작은구멍을 뚫은 이물질 유입억제용 단관(5)을 끼워서 구성한 것이다.As shown in FIG. 3, the air discharge means used so far has an inverted U-shaped elongated hose having an elasticity in the upper end portion 3 of the air discharge pipe 2 having the outlet on one side of the automatic transmission 1 facing upward ( 4) is fitted by fitting, and the inside of the opposite discharge end is fitted by inserting a short pipe (5) for preventing the inflow of foreign substances perforated small holes.

그러나, 이와같은 구성의 호스는 이물질의 유입을 억제하기 위하여 그 길이를 상대적으로 길게 하고 있으므로 배치상 복잡하여 조립작업이 불편하며, 또한 동절기에는 호스 내부공간의 공기의 결빙으로 막힘현상이 발생하여 제기능을 발휘할 수 없을 뿐만 아니라 이물질 유입억제용 단관을 사용하더라도 미세한 먼지 등의 이물질 유입을 억제하는데는 미흡한 문제점이 있었다.However, since the hose of such a configuration has a relatively long length in order to suppress the inflow of foreign substances, it is complicated in arrangement and inconvenient to assemble, and in winter, clogging occurs due to freezing of the air in the inner space of the hose. Not only can not exert a function, there is also a problem to suppress the inflow of foreign matter, such as fine dust even when using a short pipe for inhibiting foreign matter inflow.

따라서, 본 고안의 목적은 캡 타입으로 체적을 작게하여 그 내면에 통기로, 즉 에어배출로를 나선형으로 구성함으로써, 통기로의 길이를 최대로 연장하여 에어배출이 자유롭고 이물질 유입의 차단효과가 뛰어나며, 또한 조립성이 양호함은 물론 제작단가가 저렴한 오토매틱 트랜스미션의 에어배출용 캡을 제공하는데 있다.Therefore, the object of the present invention is to reduce the volume of the cap type to form a vent on the inner surface, that is, the air discharge passage in a spiral, to extend the length of the passage to the maximum free air discharge and excellent blocking effect of foreign matter inflow In addition, the present invention provides a cap for the air discharge of an automatic transmission that has good assemblability and a low manufacturing cost.

이하, 본 고안을 첨부도면에 따라 구체적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제 1 도 및 제 2 도에 나타난 바와 같이, 오토매틱 트랜스미션(1) 일측의 출구가 상방을 향하는 상단에 확개부(3)를 형성한 공지의 에어배출관(2)에 있어서, 상기 에어배출관(2)에 끼움설치하는 캡(6)은 그 내부중앙에 에어배출관(2) 상단의 확개부(3) 내면과 동형의 끼움돌부(7)를 일체로 형성하여 경사상의 유입로(8)를 상부의 공간부(9)와 연통되도록 하고, 내면의 상기한 공간부(9)와 연접되는 지점 하부에 나선형의 통기로(10)를 형성하여 상기한 공간부(9)와 연통되도록 구성한 것이다.As shown in FIG. 1 and FIG. 2, in the well-known air exhaust pipe 2 in which the expansion part 3 was formed in the upper end which the exit of one side of the automatic transmission 1 faces upwards, the said air exhaust pipe 2 is carried out. The cap 6 to be fitted in the interior of the air outlet tube 2 is formed integrally with the inner part of the expansion part 3 of the upper part of the air outlet pipe 2 so as to integrally form an inclined inlet 7 with an inclined inflow path 8 in the upper space. It is configured to communicate with the space (9), and to form a helical vent (10) in the lower portion of the point that is in contact with the space (9) of the inner surface is configured to communicate with the space (9).

이와같이 구성된 본 고안의 에어배출용 캡(6)은 오토매틱 트랜스미션(1)의 에어배출관(2) 상단에 끼움식으로 간단히 고정설치 하는 것으로, 그 끼움상태는 제 2 도에 잘 나타나 있다.The air discharge cap 6 of the present invention configured as described above is simply fixed to the top of the air discharge pipe 2 of the automatic transmission 1 by fitting, and the fitted state is well shown in FIG. 2.

이러한 상태에서 오토매틱 트랜스미션(1) 내부에서 발생하는 에어는 에어배출관(2)을 거쳐서 끼움돌부(7)내의 경사상의 유입로(8), 공간부(9) 그리고 나선형의 통기로(10)를 통하여 외부로 배출 되는 것이다.In this state, the air generated inside the automatic transmission (1) is passed through the air discharge pipe (2) through the inclined inflow path (8), the space (9) and the helical vent (10) in the fitting portion (7). It is discharged to the outside.

그리고, 에어가 마지막 에어배출로인 나선형의 통기로(10)를 거치는 과정인 배출은 적정압에 의하여 자유롭게 이루어지더라도, 그와는 반대로 이물질이 통기로(10)의 나선형을 역방향으로 돌아서 유입될 수 없는 것이다.And, even though the discharge is a process of passing the air through the helical aeration passage 10, which is the last air discharge passage, is freely made by the appropriate pressure, on the contrary, foreign substances are introduced by turning the helical passage of the aeration passage 10 in the reverse direction. I can't.

이상 설명한 바와같이, 본 고안의 에어배출용 캡은 적은 체적의 캡타입으로 에어배출이 자유롭고 이물질의 유입차단효과가 뛰어나며, 조립성이 양호할 뿐만 아니라 제작단가가 저렴한 매우 유용한 고안인 것이다.As described above, the cap for air discharge of the present invention is a small volume cap type that is free of air discharge and excellent inflow blocking effect of foreign substances, good assembly properties and low production cost is a very useful design.
