본 고안은 캠축으로 오일펌프를 구동하는 자동차 엔진윤활장치에 관한 것이다.The present invention relates to an automotive engine lubricator for driving an oil pump with a camshaft.

종래의 엔진윤활장치는 제2도와 같이 오일펌프(21)를 크랭크축(22)에 연결하고 오일필터(23)를 주오일통로(24)에 연결하며 오일필터(23)는 오일팬(25)내에서 흡인파이프(26)로 연결하여, 오일팬(25)에서 오일스크린(27)을 거쳐 흡인파이프(26)로 들어오는 오일이 오일펌프(21)에 의하여 오일필터(23)를 거쳐 주오일통로(24)로 들어갔다가 실린더헤드의 오일통로(28)를 통해 캠축(29)등에 공급된 후 다시 오일팬(25)으로 귀환되도록 하고 있었다.The conventional engine lubricator connects the oil pump 21 to the crankshaft 22, the oil filter 23 to the main oil passage 24, and the oil filter 23 is an oil pan 25 as shown in FIG. The oil flowing into the suction pipe 26 through the oil screen 25 from the oil pan 25 through the oil pipe 23 is connected to the suction pipe 26 within the main oil passage through the oil filter 23 by the oil pump 21. After entering (24), it was supplied to the camshaft 29 through the oil passage 28 of the cylinder head, and then returned to the oil pan 25 again.

그러나 이러한 종래의 윤활장치는 오일펌프가 크랭크축에 의하여 구동되면서 오일팬의 오일을 상측으로 쏘아올리는 형식이기 때문에 펌프의 능력이 상대적으로 커야 하고 오일의 관성력을 이용하지 못하며 오일펌프가 크랭크축과 1 : 1 로 회전하기 때문에 오일량부족으로 인한 스커핑이 발생할 소지가 다분히 있었던 것이다.However, such a conventional lubrication device is a type of pumping the oil of the oil pan upward while the oil pump is driven by the crankshaft, so the capacity of the pump must be relatively large and the oil pump cannot use the inertia force of the oil pump. : There was a lot of possibility of scuffing due to lack of oil because it rotates to 1.

본 고안은 오일펌프를 크랭크축이 아닌 캠축을 이용해 회전비가 다르게 구동할 수 있고 오일의 관성을 이용하여 실린더헤드로 부터 오일이 거꾸로 흘러내러 올 수 있도록 하여 엔진의 윤활효과를 개선하고, 또 엔진의 높이도 축소시킬 수 있도록 하는데 그 목적이 있는 것이다.The present invention improves the lubrication effect of the engine by allowing the oil pump to be driven differently by the camshaft rather than the crankshaft and by allowing the oil to flow backwards from the cylinder head by using the inertia of the oil. Its purpose is to reduce the height.

본 고안은 상기 목적은 달성하기 위하여 오일팬의 일측에 오일의 송출량 이상의 오일저장용량을 갖는 흡인파이프를 일체로 형성하여 오일펌프와 연결시키고, 상기 오일펌프는 크랭크축의 회전수 이상의 회전수를 갖도록 캠축과 연결시키며, 상기 오일펌프와 연결되는 오일필터를 실린더헤드의 오일통로와 연결시킨 것이다.The present invention is connected to the oil pump by integrally forming a suction pipe having an oil storage capacity of more than the amount of oil delivery to one side of the oil pan to achieve the above object, the oil pump has a rotation speed of the crankshaft or more of the camshaft The oil filter connected to the oil pump is connected to the oil passage of the cylinder head.

이하 본 고안의 실시예를 도면에 의하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the drawings.

본 고안은 제1도에 도시하는 바와 같이 오일팬(1)을 높이가 낮게 형성하고 그 일측에 오일의 송출량 이상의 오일저장용량을 갖는 흡인파이프(2)를 일체로 형성하여 오일팬(1)의 용적을 실질적으로 확장시키며, 이러한 흡인파이프(2)의 상단은 오일펌프(3)에 연결한 것으로, 오일펌프(3)는 크랭크축(4)의 회전수 이상의 회전수를 갖도록 캠축(5)과 연결시키는 바 이것은 예컨대, 캠 샤프트 타이밍 기어 외측에서 캠축(5)에 캠축 풀리(6)를 설치하고 오일펌프(3)의 축에 상기 캠축 풀리(6)와 벨트(7)로 연결되는 펌프축 풀리(8)를 설치하며 그 회전비를 캠축 대비 펌프축이 1 : 4 를 이루도록 하여 오일펌프(3)의 회전수가 크랭크축(4)의 회전수의 2 배 정도를 갖도록 한 것이다.In the present invention, as shown in FIG. 1, the oil pan 1 is formed with a low height, and on one side thereof, the suction pipe 2 having an oil storage capacity equal to or greater than the amount of oil delivery is integrally formed. It substantially expands the volume, the upper end of the suction pipe (2) is connected to the oil pump (3), the oil pump (3) and the cam shaft (5) so as to have a rotational speed or more than the rotation speed of the crankshaft (4) This is for example provided with a camshaft pulley 6 on the camshaft 5 outside the camshaft timing gear and a pumpshaft pulley connected to the camshaft pulley 6 and the belt 7 on the shaft of the oil pump 3. (8), the rotation ratio of the pump shaft to the cam shaft to achieve 1: 4 so that the rotation speed of the oil pump (3) has about twice the rotation speed of the crank shaft (4).

또, 상기 오일펌프(3)와 연결되는 오일필터(9)의 출구측은 실린더헤드의 오일통로(10)에 연결한 것이다.In addition, the outlet side of the oil filter 9 connected to the oil pump 3 is connected to the oil passage 10 of the cylinder head.

따라서 오일펌프(3)는 크랭크축(4)의 1/2 에 해당하는 회전수로 회전되는 캠축(5)의 4 배속으로 회전하여 오일팬(1)내의 오일을 흡인파이프(2)를 통해 흡인시킨 후 가압하여 오일필터(9)를 통해 실린더헤드의 각부(캠축, 캠 및 밸브, 로커암, 로커암축)로 보내진 오일은 실린더 블록을 거쳐 오일팬(1)내로 다시 귀환하게 되는 것이다.Therefore, the oil pump 3 rotates at four times the speed of the camshaft 5 which is rotated at the rotational speed corresponding to 1/2 of the crankshaft 4 to suck the oil in the oil pan 1 through the suction pipe 2. After pressurizing, the oil sent to each part of the cylinder head (camshaft, cam and valve, rocker arm, rocker arm shaft) through the oil filter 9 is returned to the oil pan 1 via the cylinder block.

이와 같은 본 고안은 오일펌프가 기존에 크랭크축과 등일하게 회전되는 오일펌프보다도 더욱 큰 회전수로 회전될 수 있어 송유량을 증대시키는 효과가 있고 이로 말미암아 오일량부족으로 인한 스커핑의 발생확률이 적어지며 오일을 실린더헤드로 부터 오일팬쪽으로 내려보내기 때문에 실린더헤드에서 떨어질 때 관성력이 오일에 작용하여 오일의 윤활효과가 개선되고, 또 오일팬의 용량을 흡인파이프에서도 차지하고 있으므로 오일팬의 용적을 줄일 수 있어 상대적으로 오일팬의 높이가 낮아지므로 결국 엔진의 높이가 축소되는 등의 효과가 있는 것이다.The present invention has the effect of increasing the flow rate because the oil pump can be rotated at a larger rotation speed than the conventional oil pump that is rotated equally with the crankshaft, and thus the probability of occurrence of scuffing due to lack of oil Since the oil is lowered from the cylinder head toward the oil pan, the inertia force acts on the oil when it falls off the cylinder head, improving the oil lubrication effect, and also reducing the volume of the oil pan since the oil pan occupies the capacity of the suction pipe. Since the height of the oil pan is relatively low, the height of the engine is eventually reduced.
