본 고안은 차량변속기 내부압력저감용 브리더에 관한 것으로, 특히 적은 압력하에서도 작동이 용이하면서도, 조립공수가 적어 조립이 용이하도록 된 차량변속기 내부압력저감용 브리더에 관한 것이다.The present invention relates to a breather for reducing the internal pressure of the vehicle transmission, and more particularly to a breather for reducing the internal pressure of the vehicle transmission that is easy to operate under low pressure, and easy to assemble due to the low assembly labor.

일반적으로 차량변속기 내부의 압력이 높아지게 되면 이를 배출시켜 변속기내부를 항상 적정압력으로 유지시켜야만 되므로 이를 위해 브리더가 사용되어지는데, 종래에는 제3도에 도시된 바와 같이, 외주면의 한곳에 공기배출홀(101b)을 형성한 캡(101)의 내부에; 스프링(104)과, 이 스프링(104)을 지지하는 러버패드(103) 및, 이 러버패드(103)에 접촉되는 삽입부재(102)의 상단부위가 삽입되되, 상기 삽입부재(102)에는 몸체(102d)의 중앙부위에 형성된 플랜지(102b)의 상단부에 외주면을 따라 소정폭으로 홈(102c)이 구비됨과 더불어 내부를 관통하는 공기경로홀(102a)이 형성되어져 있다.In general, when the pressure inside the vehicle transmission increases, it is necessary to maintain the inside of the transmission at a proper pressure at all times by discharging it, so that a breather is used for this purpose, as shown in FIG. In the cap 101 formed; A spring 104, a rubber pad 103 supporting the spring 104, and an upper end portion of the insertion member 102 in contact with the rubber pad 103 are inserted, and the body is inserted into the insertion member 102. A groove 102c is provided along the outer circumferential surface of the flange 102b formed at the central portion of the 102d with a predetermined width, and an air path hole 102a penetrating therein is formed.

따라서, 변속내의 압력이 높아 제4도에 도시된 바와 같이, 삽입부재(102)의 공기경로홀(102a)을 통해 변속기내의 공기가 흐르게 되면 이로 인해, 러버패드(103)가 스프링(104)을 압축시키게 되고, 유입공기 압력에 의해 스프링(104)의 압축되고 나면 캡(101) 내부의 압력상승에 따라 삽입부재(102)가 밑으로 이동되어지면서, 상기 삽입부재(102)의 홈(102c)과 캡(101) 내부로 돌출된 오목홈(101a) 사이에 틈이 발생되고, 이로 인해 상기 캡(101) 내부의 공기가 흐르면서 오목홈(101a)에 형서된 공기배출홀(101b)로 빠져나가게되는 한편, 변속기내부의 압력이 낮아 공기의 유입이 없게되면 스프링(104)의 복원력에 의해 초기상태로 돌아가게 된다.Therefore, as the pressure in the shift is high, as shown in FIG. 4, when the air in the transmission flows through the air path hole 102a of the insertion member 102, the rubber pad 103 causes the spring 104 to move. After the compression of the spring 104 by the inlet air pressure, the insertion member 102 is moved downward in accordance with the increase in pressure inside the cap 101, the groove 102c of the insertion member 102. And a gap is generated between the concave groove 101a protruding into the cap 101, thereby causing the air inside the cap 101 to flow out into the air discharge hole 101b formed in the concave groove 101a. On the other hand, when the pressure inside the transmission is low so that no inflow of air is returned to the initial state by the restoring force of the spring (104).

또한 상기 캡(101)의 내부로 돌출된 오목홈(101a)은 높은 압력으로 유입되는 공기에 의해 삽입부재(102)가 이탈되는 것을 방지하게 된다.In addition, the concave groove 101a protruding into the cap 101 prevents the insertion member 102 from being separated by air introduced at a high pressure.

그러나 이와 같이 변속기내부의 압력이 캡(101)내에 삽입되어 러버패드(103)를 매개로 삽입부재(102)에 지속적인 힘을 가하는 스프링(104)의 힘을 이겨내는 경우 즉, 변속내부의 압력이 스프링(104)의 힘보다 클 경우에만 변속기내부의 공기가 배출되어지는 문제가 있었다.However, when the pressure inside the transmission is inserted into the cap 101 to overcome the force of the spring 104 which exerts a constant force on the insertion member 102 via the rubber pad 103, that is, the pressure inside the transmission is There is a problem that the air inside the transmission is discharged only when the force of the spring 104 is greater.

이에 본 고안은 이와 같은 문제를 해소하기 위해 고안된 것으로, 변속기내부의 압력이 대기압력보다 높을 경우에 항상 작동될 뿐만 아니라, 부품수를 줄여 조립이 용이하도록 된 차량변속기 내부압력저감용 브리더를 제공함에 그 목적이 있다.Therefore, the present invention is designed to solve such a problem, and it is not only always operated when the pressure inside the transmission is higher than the atmospheric pressure, but also to provide a breather for reducing the internal pressure of the vehicle transmission that is easy to assemble by reducing the number of parts. The purpose is.

상기와 같은 목적을 달성하기 위한 본 고안은, 고무재질인 캡에 삽입부재가 삽입되되, 상기 삽입부재는 내부를 관통하는 공기경로를 갖춘 몸체와, 이 몸체의 선단부에 공기경로홀과 연결되는 공기경로를 갖춘 상부플랜지 및, 이 플랜지에서 소정간격으로 형성된 하부플랜지로 이루어지는 한편, 상기 삽입부재와 결합되는 캡에는 하단부위에 개구된 삽입홀과, 이 삽입홀로 부터 소정위치에 구비되어 하부홈과 상부홈으로 양분하면서 중앙에 삽입홀을 갖춘 플랜지로 이루어짐과 더불어, 상단부위에서 상부홈에 연결되도록 개구된 공기배출홀이 구비된 구조로 되어 있다.The present invention for achieving the above object, the insertion member is inserted into the cap of the rubber material, the insertion member is a body having an air path penetrating through the inside, the air is connected to the air path hole in the front end of the body An upper flange having a path and a lower flange formed at predetermined intervals from the flange, while the cap coupled to the insertion member includes an insertion hole opened at a lower end portion, and a lower groove and an upper groove provided at a predetermined position from the insertion hole. In addition to the bifurcated into a flange having an insertion hole in the center, and has a structure provided with an air discharge hole opened to be connected to the upper groove at the upper end.

이하 본 고안을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안에 따른 브리더의 결합단면도를 도시한 것인바, 고무재질인 캠(1)에 삽입부재(2)가 삽입되되, 상기 삽입부재(2)는 내부를 관통하는 공기경로홀(2a)을 갖춘 몸체(2e)와, 이 몸체(2e)의 선단부에서 공기경로홀(2a)과 연결되는 공기경로홀(2b)을 갖춘 상부플랜지(2c) 및, 이 플랜지(2c)에서 소정간격으로 형성된 하부플랜지(2d)로 이루어지게 된다.1 is a cross-sectional view of the coupling of the breather according to the present invention, the insertion member 2 is inserted into the cam 1 of the rubber material, the insertion member 2 is an air path hole (2a) penetrating through the inside ) Upper flange 2c having a body 2e having a side face, an air path hole 2b connected to an air path hole 2a at the tip of the body 2e, and a predetermined distance from the flange 2c. The lower flange 2d is formed.

또한, 상기 삽입부재(2)와 결합되는 캠(1)에는 하단부위에 개구된 삽입홀(1f)과, 이 삽입홀(1f)로부터 소정위치에 구비되어 하부홈(1c)과 상부홈(1b)으로 양분하면서 중앙에 삽입홀(1e)을 갖춘 플랜지(1d)로 이루어짐과 더불어 상단부위에서 상부홈(1b)에 연결되도록 개구된 공기배출홀(1a)이 구비되어진다.In addition, the cam 1 coupled to the insertion member 2 is provided with an insertion hole 1f opened at a lower end portion, and is provided at a predetermined position from the insertion hole 1f to provide a lower groove 1c and an upper groove 1b. It consists of a flange (1d) having an insertion hole (1e) in the center while dividing into the air discharge hole (1a) is opened to be connected to the upper groove (1b) at the upper end.

따라서, 변속기내의 압력이 피기압보다 높아져 제2도에 도시된 바와 같이 삽입부재(2)의 공기경로홀(2a)을 통해 캠(1)의 상부홈(1b)으로 유입되어지면, 상기 상부홈(1b)에 채워진 공기압력에 의해 캠(1)이 위로 이동되며, 상기 삽입부재(2)의 하부플랜지(2d)가 캠(1)의 하부홈(1c)의 하부에 접촉되게 되면, 상기 캠(1)의 공기배출홀(1a)과 일치된 삽입부재(2)의 상부플랜지(2c)에 형성된 공기배출홀(2b)을 통해 유입공기가 배출되어지게 된다.Therefore, when the pressure in the transmission is higher than the piggy pressure and flows into the upper groove 1b of the cam 1 through the air path hole 2a of the insertion member 2, as shown in FIG. When the cam 1 is moved upward by the air pressure filled in 1b, and the lower flange 2d of the insertion member 2 comes into contact with the lower portion of the lower groove 1c of the cam 1, the cam Inlet air is discharged through the air discharge hole 2b formed in the upper flange 2c of the insertion member 2 coinciding with the air discharge hole 1a of (1).

그리고, 변속기내부의 압력이 낮아 삽입부재(2)의 공기경로홀(2a)로 공기가 유입되지 않게 되면, 캠(1)이 처음위치로 복귀되게 된다.When the pressure inside the transmission is low and no air flows into the air path hole 2a of the insertion member 2, the cam 1 is returned to the initial position.

이상 설명한 바와 같이 본 고안에 의하면, 변속기내부의 압력이 높을때 공기를 배출시켜 압력을 낮추는 브리퍼가 캡에 삽입부재를 끼워 결합시키게 되어 조립이 용이할 뿐만 아니라, 변속기내부의 압력에 저항하는 저항력이 없게 되어 변속기내부의 압력이 높게 되면 항상 배출되어져 변속기내부의 압력이 최상으로 유지되는 효과가 있다.As described above, according to the present invention, when the pressure inside the transmission is high, a briefer for discharging air by lowering the pressure is inserted into the cap so that the insertion member can be combined to facilitate the assembly, and the resistance to the pressure inside the transmission is increased. When the pressure inside the transmission is high, it is always discharged, so that the pressure inside the transmission is maintained at the highest level.
