Description
본 발명은 오일펌프의 열화방지장치에 관한 것이다.The present invention relates to an apparatus for preventing deterioration of an oil pump.
엔진은 고속으로 운동하고 연소실 주변은 고열에 노출되어 있어 윤활 및 냉각을 위하여 크랭크축 베어링이나 캠축 베어링 등에 오일을 공급하게 된다.The engine moves at high speed and the combustion chamber is exposed to high heat, supplying oil to crankshaft bearings or camshaft bearings for lubrication and cooling.
오일을 급송하는 수단으로는 오일펌프에 의한 강제 급송수단을 주로 사용하며 오일펌프는 통상 크랭크축의 회전력을 이용하여 구동토록 되어 있다.As a means of feeding oil, a forced feeding means by an oil pump is mainly used, and the oil pump is usually driven by using the rotational force of the crankshaft.
그런데 엔진을 순환하는 오일은 엔진열을 받아 온도가 상승하고 더우기 오일펌프에서 고압으로 압축되어 급송하게 될 때 더욱 온도가 높아져 열화되기 쉬우며 엔진 오일이 열화될 경우 점도가 떨어져 제 기능을 발휘하기 어렵게 된다.However, the oil that circulates in the engine increases in temperature due to the heat of the engine and, moreover, when it is compressed and fed at high pressure from the oil pump, the temperature becomes higher and is more likely to deteriorate. do.
한편 엔진에 공급되는 공기는 에어크리너와 서지탱크를 통해 각 실린더로 유입되어지게 되나 서지탱크는 구조상 일측 유입구와 흡기매니폴드가 거의 직각 방향을 이루도록 접속되어 있기 때문에 유입구를 통해 서지탱크 내부로 들어온 공기가 반대편 벽면에 충돌하여 흡기매니폴드로의 원활한 흐름을 방해하고 소음을 발생시키는 문제점이 있다.On the other hand, the air supplied to the engine is introduced into each cylinder through the air cleaner and the surge tank, but since the surge tank is structurally connected so that one inlet port and the intake manifold are almost perpendicular to each other, the air entered into the surge tank through the inlet port. There is a problem that impinges on the opposite wall to interfere with the smooth flow to the intake manifold and generate noise.
이에 본 발명은 상기한 각각의 문제점을 해결코자 제안된 것으로서 그의 목적으로 하는 것은 서지탱크로 유입되는 공기가 부딪히는 벽면으로부터 공기를 인출하여 오일펌프의 구동기어에 공급하므로써 서지탱크의 소음 발생을 줄이고 오일을 냉각시켜 열화를 방지토록한 오일펌프의 열화방지장치를 제공하는데 있다.Therefore, the present invention has been proposed to solve each of the above problems, and its object is to draw out air from the wall hit by the air flowing into the surge tank and to supply the driving gear of the oil pump to reduce the noise of the surge tank and reduce the oil. It is to provide a deterioration preventing device of the oil pump to prevent deterioration by cooling.
상기한 목적을 달성하기 위한 본 발명은 에어크리너측 유입구와 흡기매니폴드가 거의 직각으로 접속되는 서지탱크와; 펌프 흡입구와 펌프 토출구를 갖는 하우징과 하우징 내에서 맞물려 회전하여 오일을 펌프 토출구측으로 압송하는 한쌍의 구동기어를 포함하는 오일펌프와; 서지탱크의 유입구에 대향되는 공기 충돌 벽면으로부터 오일펌프측에 접속되는 공기공급라인과; 상기 공기공급라인으로부터 공급되는 공기가 회전축을 통하여 구동기어 몸체 내부를 순환하도록 형성되는 공기냉각통로와; 상기 공기냉각통로를 순환하면서 오일과 열교환된 공기를 다시 에어크리너측에 되돌리는 공기리턴라인과; 를 포함하여 구성되는 것을 특징으로 한다.The present invention for achieving the above object is a surge tank which is connected to the air cleaner side inlet and the intake manifold at a right angle; An oil pump including a housing having a pump suction port and a pump discharge port, and a pair of drive gears which rotate in engagement with the pump and feed oil to the pump discharge port; An air supply line connected to an oil pump side from an air collision wall facing the inlet of the surge tank; An air cooling passage formed so that air supplied from the air supply line circulates inside the drive gear body through a rotating shaft; An air return line circulating the air cooling passage and returning air exchanged with oil back to the air cleaner; Characterized in that comprises a.

제1도는 본 발명의 전체 구성을 나타내는 개략도이며, 제2도는 본 발명의 오일펌프를 나타내는 도면이며, 제3도는 본 발명의 구동기어의 측단면도를 나타내는 도면이다.FIG. 1 is a schematic diagram showing the overall configuration of the present invention, FIG. 2 is a diagram showing the oil pump of the present invention, and FIG. 3 is a side cross-sectional view of the drive gear of the present invention.
도면중 부호 1은 대략 직사각형 형상의 통체인 서지탱크이며 에어크리너(2)측에 연통하는 일측 유입구(3)와 거의 직각으로 흡기매니폴드(4)가 접속되어 있다.In the figure, reference numeral 1 denotes a surge tank which is a cylindrical body having a substantially rectangular shape, and an intake manifold 4 is connected at a substantially right angle to one inlet port 3 communicating with the air cleaner 2 side.
상기 에어크리너(2) 측으로부터 유입구(3)를 통하여 유입된 공기가 부딪히는 반대측의 서지탱크 벽면(5)에는 공기공급관로(6)의 일단이 접속되며 공기공급관로(6)의 타단은 오일펌프(7), 구체적으로는 구동기어축(8)에 접속된다.One end of the air supply line 6 is connected to the surge tank wall 5 on the opposite side where the air introduced through the inlet 3 from the air cleaner 2 side hits, and the other end of the air supply line 6 is an oil pump. (7), specifically, is connected to the drive gear shaft 8.
상기 오일펌프(7)는 펌프 흡입구(9)와 펌프 토출구(10)를 갖는 하우징(11) 및 하우징(11) 내에서 맞물려 회전하여 오일을 압송하는 한쌍의 구동기어(12)(12)로 구성되며 구동기어축(8)과 기어(12) 몸체 내에는 공기공급라인(6)에 접속되어 서지탱크(1)측의 공기(신기)가 순환하게 되는 공기냉각통로(13)(14)가 형성되어 있으며 구동기어 몸체 내부를 순환한 공기는 구동기어축(8)에 형성된 공기리턴라인(15)을 통하여 빠져나가 에어크리너(2)로 되돌려져 다시 서지탱크(1)에 공급되어지게 된다.The oil pump 7 is composed of a housing 11 having a pump inlet 9 and a pump outlet 10, and a pair of drive gears 12 and 12 that rotate and engage in the housing 11 to feed oil. Air cooling passages 13 and 14 are formed in the drive gear shaft 8 and the body of the gear 12 so as to be connected to the air supply line 6 to circulate air in the surge tank 1 side. The air circulated in the drive gear body exits through the air return line 15 formed in the drive gear shaft 8 and is returned to the air cleaner 2 to be supplied to the surge tank 1 again.
이와 같이 서지탱크에 유입되어 벽면에 충돌하게 되는 차가운 공기를 빼내어 오일펌프의 구동기어 몸체 내를 순환시켜 오일 냉각은 행할 수 있게 되는 것이다.In this way, the cool air that flows into the surge tank and collides with the wall is removed, and the oil is cooled by circulating in the drive gear body of the oil pump.
이상과 같은 본 발명은 서지탱크 벽면에 충돌하는 공기를 외부로 유출시키게 되므로 흡기매니폴드를 통해 공급되는 공기와 충돌을 일으켜 유동 특성을 저하시키는 일이 없고 소음 발생도 줄어들게 되며, 서지탱크로부터 빼낸 차가운 공기는 오일펌프의 구동기어 몸체를 순환하도록 공급하므로써 오일을 냉각시켜 열화를 방지하여 엔진기능을 정상으로 유지시키게 되는 효과가 있다.In the present invention as described above, the air colliding with the surge tank wall is leaked to the outside, so that it does not collide with the air supplied through the intake manifold, thereby reducing the flow characteristics and reducing the noise, and removing the cold air from the surge tank. Air is supplied to circulate the drive gear body of the oil pump to cool the oil to prevent deterioration, thereby maintaining the engine function normal.
