Description
본 발명은 윤활계의 이상경고장치에 관한 것이다.The present invention relates to an abnormality warning device of the lubrication system.
엔진의 캠축, 밸브트레인, 크랭크축 및 피스톤등 각 운동부에는 마모를 방지하기 위한 목적 및 부재가 과열되어 손상되는 것을 피하기 위하여 엔진오일을 공급하고 있다.Engine oils are supplied to each of the moving parts such as the camshaft, valve train, crankshaft, and piston of the engine in order to prevent wear and to prevent overheating and damage to the members.
이 엔진오일은 도 3에 도시하는 것과 같이 오일팬(1)내에 저장된 오일을 오일펌프(2)로 퍼올려 급송하게 되며 도중에 엔진오일속에 포함된 이물질을 제거하기 위하여 오일여과기(8)를 거쳐 공급하게 된다.As shown in FIG. 3, the engine oil is pumped up by supplying oil stored in the oil pan 1 to the oil pump 2 and supplied through the oil filter 8 to remove foreign substances contained in the engine oil. Done.
상기 오일여과기(8)는 오일속에 포함된 이물질 여과에 의해 필터(7)가 막히게 되면 오일갤러리에 공급되는 오일량이 줄어들어 부재들을 마모 및 소착시키게 되기 때문에 필터압이 높아지면 바이패스밸브(18)가 열려 여과되지 아니한 오일이 오일갤러리로 급송되도록 되어 있다.When the filter 7 is blocked by the filtration of foreign substances contained in the oil, the oil filter 8 reduces the amount of oil supplied to the oil gallery, which causes wear and squeeze of the members. Unopened oil is fed to the oil gallery.
그러나 오일의 바이패가 지속되면 오일속에 함유된 이물질이 각 운동부의 마찰면에 끼여서 부재의 마모를 촉진하게 되므로 오일여과기(5)를 교체하여 주어야한다.However, if the oil by-pass persists, foreign matter contained in the oil is caught on the friction surface of each moving part to promote the wear of the member, so the oil filter (5) should be replaced.
교체시점을 정확히 알 수 없다는 문제점이 있으며 또한 오일공급관로(3)상에 유압계(19)를 설치하여 엔진오일의 적정 공급압을 체크토록 하고 있으나 이 역시 엔진룸을 열고 수시로 확인하여 주어야 하므로 불편하다는 문제점이 지적되고 있다.There is a problem that it is not possible to know the exact time of replacement, and the hydraulic system 19 is installed on the oil supply line 3 to check the proper supply pressure of the engine oil, but this is also inconvenient because the engine room must be opened and checked at any time. The problem is pointed out.
이에 본 발명은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 바는 기존에 오일공급압을 체크하기 위해 장착되어져 있던 유압계를 삭제하고 바이패스밸브 개방작동 및 유압센서에 의한 전기적 신호를 통해 시각적으로 오일압의 이상과 오일여과기의 이상유무를 확인할 수 있는 윤활계의 이상경고장치를 제공하는 데 있다.Accordingly, the present invention has been proposed in view of the above-mentioned problems, and its purpose is to delete the hydraulic system that has been previously installed to check the oil supply pressure, and through the bypass valve opening operation and the electrical signal by the hydraulic sensor. An object of the present invention is to provide an abnormality warning device for a lubrication system that can visually confirm an abnormality in oil pressure and an oil filter.
상기한 목적을 달성하기 위하여 본 발명은 오일팬내의 오일을 퍼올려 급송하는 오일펌프와, 오일속에 포함된 이물질을 여과하는 오일여과기를 포함하는 윤활계에 있어서, 오일펌프의 토출압을 검출하기 위하여 오일공급관로상에 설치되는 유압센서와; 상기 유압센서로부터 검출된 유압이 기준치 이하일 때 신호를 출력하는 전자제어장치와; 상기 오일여과기의 필터가 막혀 필터전후의 압력차가 일정치 이상일 때 회로를 온 접속하는 위치까지 개방되어 오일을 바이패스 공급하는 바이패스밸브와; 및 상기 전자제어장치로부터 신호출력이 있거나 또는 상기 바이패스밸브가 개방되어 스위치 접속될 때 점등되는 경고등과; 를 포함하여 구성되는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a lubricating system including an oil pump for pumping up and feeding oil in an oil pan, and an oil filter for filtering foreign substances contained in the oil, in order to detect the discharge pressure of the oil pump.

이하 본 발명의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.
도 1은 본 발명에 의한 윤활계의 이상경고장치를 나타내는 도면이며 도 2는 본 발명의 바이패스밸브의 상세도이다.1 is a view showing an abnormality warning device of the lubrication system according to the present invention, Figure 2 is a detailed view of the bypass valve of the present invention.
도면중 부호 1은 오일팬이며 오일팬(1)내에 저장된 엔진오일은 오일펌프(2)에 의해 퍼올려져 오일공급관로(3)를 통하여 오일갤러리로 급송된다.In the drawing, reference numeral 1 denotes an oil pan, and engine oil stored in the oil pan 1 is pumped up by the oil pump 2 and fed to the oil gallery through the oil supply line 3.
상기 오일공급관로(3)의 도중에는 오일의 펌프토출압을 검출하기 위한 유압센서(4)와 오일속에 포함된 이물질을 여과하기 위한 오일여과기(5)가 설치되어 있다.In the middle of the oil supply line 3, the oil pressure sensor 4 for detecting the pump discharge pressure of the oil and the oil filter 5 for filtering the foreign matter contained in the oil is installed.
상기 오일여과기(5)는 케이스(6) 내부에 필터(7)와 필터(7)가 막혀 유압이 높아질 때 필터(7)를 거치지 않고 오일을 바이패스 공급하는 바이패스밸브(8)로 구성된다.The oil filter (5) is composed of a bypass valve (8) for bypass supplying oil without passing through the filter (7) when the filter (7) and the filter (7) inside the case (6) is blocked, the hydraulic pressure is high. .
상기 바이패스밸브(8)는 오일압에 의해 이동하여 통로(9)를 개방하는 밸브(10)와 밸브(10)를 탄발지지하는 스프링(11)과 절연체의 밸브 지지케이싱(12)에 고정되는 고정접점(13)과 상기 밸브(10)에 고정되어 함께 이동하는 가동접점(14)을 포함하여 구성되어 있다.The bypass valve 8 is fixed to the valve 10 which moves by oil pressure to open the passage 9, the spring 11 which supports the valve 10 and the valve support casing 12 of the insulator. The fixed contact 13 and the movable contact 14 which are fixed to the said valve 10 and move together are comprised.
상기 고정접점(13)과 가동접점(14)은 서로 접촉하게 되면 회로를 접속하게 되는 스위치로서 회로의 온 접속시 운전석 계기판에 마련된 경고등(15)을 점등시키게 된다.When the fixed contact 13 and the movable contact 14 are in contact with each other, the switch is connected to the circuit to turn on the warning light 15 provided in the driver's seat instrument panel when the circuit is turned on.
그리고 상기 유압센서(4)는 오일펌프로부터 공급되는 오일압을 전기적 신호를 변환시켜 전자제어장치(16)에 신호 인가하게 되며 이 유압이 기준치 이하(즉 전기적 출력값이 기준치 이하)일 때 전자제어장치(16)는 신호를 출력하여 경고등(15)을 점등시키게 된다.The hydraulic sensor 4 converts an electrical signal from the oil pressure supplied from the oil pump to apply an electric signal to the electronic controller 16. When the hydraulic pressure is equal to or less than the reference value (ie, the electrical output value is equal to or less than the reference value), the electronic controller Numeral 16 outputs a signal to light the warning lamp 15.
또한 상기 필터(7)가 막혀 바이패스밸브(8)가 개방될 때 필터(7) 전후의 압력차가 기준치, 예를들면 1.5kg/㎠ 이상이 되면 밸브(10)가 스프링(11)을 압축하여 이동한 상태(점선도시)에서 가동접점(14)과 고정접점(13)이 닿아 스위치 접속되므로 역시 경고등(15)이 점등된다.In addition, when the filter 7 is clogged and the bypass valve 8 is opened, the valve 10 compresses the spring 11 when the pressure difference before and after the filter 7 becomes a reference value, for example, 1.5 kg / cm 2 or more. Since the movable contact 14 and the fixed contact 13 come into contact with each other in the moved state (dotted line), the warning lamp 15 is also turned on.
이때 운전자는 경고등(15)의 점등을 보고 오일펌프의 이상유무 및 오일필터의 교체시기를 점검하게 되는 것이다.At this time, the driver is to check the lighting of the warning light (15) to check the abnormality of the oil pump and the replacement time of the oil filter.
이상과 같은 본 발명에 의하면 오일공급관로상에 유압센서를 설치하고 또 오일여과기의 바이패스밸브에 스위치 기능을 부여하여 오일펌프의 공급유압이 기준치 이하로 떨어지거나 또는 필터가 막혀 필터 전후의 압력차가 기준치 이상이 되면 경고 등을 자동으로 점등시키게 되므로써 윤활계의 이상유무를 즉시 확인하여 필터를 교체하거나 오일펌프 및 오일공급관로의 이상을 제거토록 하여 엔진 고장을 예방하게 되는 효과가 있다.According to the present invention as described above by installing a hydraulic sensor on the oil supply line and by providing a switch function to the bypass valve of the oil filter, the supply pressure of the oil pump falls below the reference value or the filter is clogged so that the pressure difference before and after the filter When the standard value is exceeded, the warning light is automatically turned on to immediately check whether there is an abnormality in the lubrication system and replace the filter or remove the abnormality in the oil pump and oil supply line to prevent engine failure.
