본 고안은 자동차의 엔진에 오일을 공급하는 윤활장치에 관한 것으로서, 특히 오일여과기의 릴리이프밸브 대신에 압력에 따라 개폐되는 보조여과기를 설치함으로써 항상 여과된 오일을 공급할 수 있도록 한 자동차의 윤활장치에 관한 것이다.The present invention relates to a lubrication device for supplying oil to an engine of a car, and in particular, to the lubrication device of a car that can always supply filtered oil by installing an auxiliary filter that opens and closes according to pressure instead of a relief valve of an oil filter. It is about.

일반적으로 자동차의 윤활장치는 엔진의 주요 운동부분 및 밸브장치에서 실린더까지 오일을 주입하여 엔진내부의 마찰저항을 줄이고 동시에 엔진내부를 냉각시키는 장치이다.In general, the lubricator of a vehicle is a device that cools the engine at the same time by reducing the frictional resistance inside the engine by injecting oil from the main movement part of the engine and the valve device to the cylinder.

종래 자동차의 윤활장치는 제1도에 도시된 바와 같이 오일을 저장하는 오일팬(10)과, 상기 오일팬(10)에 저장된 오일을 공급하는 오일펌프(20)와, 상기 오일펌프(20)에서 공급되는 오일을 여과하는 오일여과기(30)와, 상기 오일여과기(30)에서 여과된 오일이 공급되는 윤활부(40)로 구성된다.The lubrication apparatus of the related art vehicle includes an oil pan 10 for storing oil, an oil pump 20 for supplying oil stored in the oil pan 10, and the oil pump 20 as shown in FIG. 1. It consists of an oil filter (30) for filtering the oil supplied from, and the lubrication unit 40 is supplied with the oil filtered in the oil filter (30).

그리고, 상기 오일펌프(20)와, 오일여과기(30)를 연결하는 제1오일통로(50)와, 상기 오일여과기(30)로부터 윤활부(40)로 오일을 공급하는 제2오일통로(60)와, 상기 제1오일통로(50)와 제2오일통로(60)를 연결하는 릴리이프관(70)과, 상기 릴리이프관(70) 상에 설치되는 릴리이프밸브(80)가 포함되어 구성된다.Then, the first oil passage 50 connecting the oil pump 20, the oil filter 30, and the second oil passage 60 for supplying oil from the oil filter 30 to the lubrication unit 40. ), A relief pipe (70) connecting the first oil passage (50) and the second oil passage (60), and a relief valve (80) installed on the relief tube (70) is included. It is composed.

상기와 같이 구성된 종래의 자동차의 윤활장치는 오일팬(10)에 저장된 오일을 오일펌프(20)에서 강제로 빨아올려 윤활부(40)로 공급하는 데, 상기 오일펌프(20)와 윤활부(40)사이에 설치된 오일여과기(30)는 엔진의 각 접동부분에서 발생한 금속가루나 연소잔류물 등의 이물질을 여과하여 윤활부(40)에 청정된 오일을 공급한다.The conventional lubrication device of the vehicle configured as described above is forcibly sucked oil stored in the oil pan 10 from the oil pump 20 and supplied to the lubrication part 40. The oil pump 20 and the lubrication part ( The oil filter 30 installed between the 40 filters foreign substances such as metal powder or combustion residues generated at each sliding portion of the engine to supply clean oil to the lubrication unit 40.

상기 오일여과기(30)는 내부의 여과지에 의해 이물질을 여과하는데 여과된 이물질이 여과지를 막아 오일투과저항이 증대되는 경우 릴리이프밸브(8)를 통해 윤활부(40)에 오일을 공급하게 된다. 즉, 오일의 투과저항이 증대되어 오일여과기(30)에 인입되는 오일의 압력이 기준압력 이상 올라가게 되면 릴리이프밸브(80)가 개방되어 오일여과기(30)를 거치지 않고 곧바로 윤활부(40)에 오일이 공급된다.The oil filter 30 filters the foreign matter by the filter paper therein, and when the filtered foreign matter blocks the filter paper and the oil permeation resistance is increased, the oil filter 30 supplies oil to the lubrication part 40 through the relief valve 8. That is, when the permeation resistance of the oil is increased and the pressure of the oil introduced into the oil filter 30 rises above the reference pressure, the relief valve 80 is opened so that the lubrication part 40 is immediately passed without passing through the oil filter 30. Oil is supplied.

그러나, 상기와 같이 구성되고 사용되는 종래 자동차의 윤활장치는 릴리이프밸브(80)를 통해 청정되지 않은 오일이 공급되기 때문에 오일내부에 함유된 이물질에 의해 엔진내부의 주요 접동부분이 손상되는 문제점이 발생되었다.However, the conventional lubrication device of the vehicle constructed and used as described above has a problem that the main sliding part of the engine is damaged by the foreign matter contained in the oil because clean oil is supplied through the relief valve 80. Occurred.

따라서, 본 고안은 상기와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 릴리이프밸브 대신에 보조여과기를 설치하여 항상 여과된 오일을 공급함으로써 엔진이 마모되는 것을 방지하도록 한 자동차의 윤활장치를 제공하는데 있다.Therefore, the present invention is devised to solve the conventional problems as described above, the object of the present invention is to install the auxiliary filter in place of the relief valve to supply the filtered oil at all times to prevent the engine wear To provide a lubrication device.

상기의 목적을 실현하기 위한 본 고안에 의한 자동차의 윤활장치는 오일팬에 저장된 오일을 공급하는 오일펌프와 상기 오일펌프에서 공급되는 오일을 여과하는 오일여과기와, 상기 오일펌프와 오일여과기를 연결하는 제1오일통로와, 상기 오일여과기로부터 윤활부로 오일을 공급하는 제2오일통로로 구성된 자동차의 윤활장치에 있어서, 상기 오일여과기로 공급되는 오일의 압력을 측정하는 오일압력센서와, 상기 제1오일통로와 제2오일통로를 연결하는 제3오일통로와, 상기 제3오일통로 상에 설치된 보조여과기와, 상기 제1오일통로와 제3오일통로를 개폐하는 밸브와, 상기 오일압력센서가 측정한 오일의 압력을 입력받아 상기 밸브를 작동하는 ECU가 포함되어 구성된 것을 특징으로 한다.The lubrication apparatus of a vehicle according to the present invention for realizing the above object is an oil pump for supplying oil stored in an oil pan and an oil filter for filtering oil supplied from the oil pump, and connecting the oil pump and the oil filter. A lubrication apparatus of a motor vehicle comprising a first oil passage and a second oil passage for supplying oil from the oil filter to the lubrication unit, comprising: an oil pressure sensor for measuring a pressure of oil supplied to the oil filter; A third oil passage connecting the passage and the second oil passage, an auxiliary filter installed on the third oil passage, a valve opening and closing the first oil passage and the third oil passage, and measured by the oil pressure sensor It is characterized in that the ECU is configured to receive the pressure of the oil to operate the valve.

Oil filter 130 for filtering the oil to be formed, and the lubrication unit 14 is supplied with the clean oil from the oil filter 130, the oil filter 130 is the pressure of the oil supplied to the oil filter The oil pressure sensor 230 to be measured, the third oil passage 270 connecting the first oil passage 150 and the second oil passage 16, and an auxiliary filter installed on the third oil passage 270. 280, the valve 250 for opening and closing the first oil passage 150, the third oil passage 270, and the oil pressure measured by the oil pressure sensor 230 are input to the valve 250. ECU 290 that operates is configured to include.

그리고, 상기 보조여과기(280)는 오일을 빨리 공급을 위하여 상기 오일여과기(130)의 필터(132)보다 조밀하지 아니한 조직의 필터(282)로 구성되고, 상기 밸브(250)는 제1오일통로(150) 사이 및 제1오일통로(150)와 제3오일통로(270) 사이를 개폐하는 삼방밸브로 구성된다.In addition, the auxiliary filter 280 is composed of a filter 282 of less dense than the filter 132 of the oil filter 130 to supply the oil quickly, the valve 250 is the first oil passage It consists of a three-way valve for opening and closing between 150 and between the first oil passage 150 and the third oil passage 270.

상기와 같이 구성된 고안에 의한 자동차의 윤활장치의 작용 및 효과는 다음과 같다.The action and effect of the lubrication device of the vehicle by the devised as described above is as follows.

오일펌프(120)에 의해 오일팬(110)에 저장된 오일이 오일여과기(130)를 통해 윤활부(140)에 오일이 공급되는 과정에서 상기 오일여과기(130)를 통과하는 오일의 압력이 일정 압력이상 상승하게 되면 오일압력센서(230)가 이를 감지하여 ECU(290)에 보낸다.In the process of supplying oil to the lubrication unit 140 through the oil filter 130 through the oil stored in the oil pan 110 by the oil pump 120, the pressure of the oil passing through the oil filter 130 is constant pressure. The oil pressure sensor 230 detects this and then sends it to the ECU 290 when the temperature rises.

상기와 같이 ECU(290)에 오일의 압력이 입력되면 상기 ECU(290)에서 닫혀있던 밸브(250)를 개방하여 보조여과기(280)를 통해서 윤활부(140)로 오일을 공급하게 된다. 이때 보조여과기(280)를 통해 공급되는 오일은 금속가루등 일정입자가 큰 이물질만이 여과된 상태로 공급된다.When the oil pressure is input to the ECU 290 as described above, the valve 250, which is closed by the ECU 290, is opened to supply oil to the lubrication unit 140 through the auxiliary filter 280. At this time, the oil supplied through the sub-filter 280 is supplied in the state that only foreign substances having a large number of certain particles such as metal powder are filtered.

상기 보조여과기(280)를 통해 오일을 공급하는 과정에서 오일압력센서(230)가 감지하는 오일의 압력이 일정압력이하로 내려가면 상기 ECU(290)에서 이를 감지하여 상기 밸브(250)를 닫아 오일여과기(130)를 통해서 오일을 공급하게 된다.When the oil pressure sensed by the oil pressure sensor 230 falls below a predetermined pressure in the process of supplying the oil through the auxiliary filter 280, the ECU 290 detects this and closes the valve 250. The oil is supplied through the filter 130.

상기와 같이 구성되어 작동되는 본 고안은 릴리이프 밸브 대신에 보조여과기(280)를 사용하여 청정된 오일을 공급하기 때문에 오일을 원활하게 공급함과 동시에 이물질에 의한 엔진 접동부의 손상을 방지할 수 있는 잇점이 있다.The present invention constructed and operated as described above uses the auxiliary filter 280 instead of the relief valve to supply clean oil, thereby smoothly supplying oil and preventing damage to the engine sliding part by foreign substances. There is an advantage.
