Description

유면 추종형 오일스트레이너{An oil surface following typed oil strainer}An oil surface following typed oil strainer}

본 발명은 유면 추종형 오일스트레이너에 관한 것으로, 보다 상세하게는 차량의 급 가속이나 제동시에도 오일의 유면으로 오일 유입구를 노출시키지 않아 공기를 흡입하지 않도록 된 유면 추종형 오일스트레이너에 관한 것이다.The present invention relates to an oil level following oil strainer, and more particularly, to an oil level following oil strainer which does not expose the oil inlet to the oil level during the rapid acceleration or braking of the vehicle so as not to inhale air.

일반적으로 고속회전을 하는 엔진에 있어서 각 베어링 메탈부위나 기어류의 치접합부 또는 피스톤 스커트부 등 습동부에는 오일이 지속적으로 일정한 압력을 유지하며 공급되어야 하며 적절한 오일의 공급은 윤활, 냉각, 세정, 방청작용 등을 통하여 엔진의 성능과 내구성을 유지시킨다.In general, in an engine that rotates at a high speed, oil is continuously supplied at a constant pressure to each bearing metal part, a toothed part of a gear, or a piston skirt part, and an appropriate oil supply is lubricated, cooled, cleaned, Maintains engine performance and durability through antirust action.

이러한 오일은 통상 도1에 도시된 바와 같이 오일펌프에 의해 오일팬(1)내의 오일속에 위치한 오일스트레이너(2) 끝단으로부터 강제로 흡입되어 엔진의 각 오일 통로를 따라 압송되게 된다.This oil is forcibly sucked from the end of the oil strainer 2 located in the oil in the oil pan 1 by the oil pump, as shown in FIG. 1, and then pumped along each oil passage of the engine.

여기서, 상기 오일스테이너(2)의 하부에는 도 2에 도시된 바와 같이 오일에 함유된 불순물을 거르도록 격자망(4)을 구비하면서 충분한 양의 오일을 유입시키도록 넓은 입구를 형성한 캡(3)이 구비되어짐은 물론이다.Here, as shown in FIG. 2, the lower portion of the oil stayer 2 includes a grid having a grid 4 to filter impurities contained in the oil, and a cap having a wide inlet for introducing a sufficient amount of oil ( 3) is provided, of course.

그러나, 이와 같이 오일팬(1)내의 오일을 유입하는 오일스테이너(2)의 오일 흡입구인 캡(3)은 평소 오일팬(1)의 오일내에 잠겨있지만 만약, 차량이 급정거하거나 급 출발하는 경우나 경사로를 주행하는 경우에는 오일의 관성력에 의해 오일이 급격하게 쏠리면서 경사진 경사유면(O')을 형성하고 이에 따라, 상기 캡(3)의 일부부위가 오일팬(1)내의 공기 중에 노출되어져 오일과 함께 공기가 흡입되는 문제가 있게 된다However, the cap 3, which is the oil inlet of the oil stayer 2, which introduces the oil in the oil pan 1, is normally locked in the oil of the oil pan 1, but if the vehicle suddenly stops or starts quickly. In the case of driving on a slope, the oil is rapidly inclined by the inertial force of the oil to form an inclined inclined oil surface O ', whereby a part of the cap 3 is exposed to the air in the oil pan 1. There is a problem that air is sucked in with the oil.

이와 같이, 상기 오일스트레이너(2)로 공기가 흡입되면 유압이 급격히 저하되어 오일의 공급이 제대로 이루어지지 않을 뿐만 아니라 오일속에 포함된 공기에의하여 습동부의 유막이 끊어지게 되는데 이는, 각종 금속 표면에 피팅(Pitting)이나 메탈(Metal)소착을 일으켜 엔진에 치명적인 손상을 주는 문제가 있게 된다.As such, when the air is sucked into the oil strainer 2, the hydraulic pressure is rapidly lowered so that the oil is not supplied properly, and the oil film of the sliding part is cut off by the air contained in the oil. There is a problem of causing damage to the engine by causing fitting or metal adhesion.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 오일스테이너의 오일흡입구가 경사진 유면을 따라 이동되어 오일팬내의 공기가 유입되지 않고 오일 만 유입되도록 함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above, and an object of the present invention is to allow the oil suction port of the oil stainer to move along the inclined oil level so that only the oil is introduced without introducing air into the oil pan.

상기와 같은 목적을 달성하기 위한 본 발명은, 오일펌프를 매개로 오일팬내의 오일속에 담가진 오일스테이너가 차량의 주행 상태에 따라 경사지는 오일의 유면을 따라 함께 이동되도록 힌지축을 매개로 결합된 유입구를 구비한 것을 특징으로 한다.The present invention for achieving the above object, the oil inlet coupled through the hinge shaft so that the oil stainer immersed in the oil in the oil pan through the oil pump is moved along the oil surface inclined according to the running state of the vehicle. Characterized in having a.

도 3은 본 발명에 따른 유면 추종형 오일스트레이너의 오일유입구 부분 구성도를 도시한 것인바, 본 발명은 오일펌프를 매개로 오일팬(1)내의 오일속에 담가진 오일스테이너(2)가 차량의 주행 상태에 따라 경사지는 오일의 유면을 따라 함께 이동되도록 힌지축(5)을 매개로 결합된 유입구(2a)를 구비하게 된다.Figure 3 shows a partial configuration of the oil inlet of the oil level following oil strainer according to the present invention, the present invention is the oil sterilizer (2) immersed in the oil in the oil pan (1) via the oil pump vehicle It is provided with an inlet (2a) coupled via the hinge shaft (5) so as to move along the oil surface of the inclined oil according to the running state of the.

여기서, 상기 유입구(2a)는 그 끝 부위를 넓게 형성한 나팔관 모양을 이루면서 그 외경으로 오일을 담을 수 있도록 소정의 공간을 형성한 오일버켓(6)이 구비되어진다.Here, the inlet (2a) is provided with an oil bucket (6) forming a predetermined space so as to contain the oil in its outer diameter while forming the shape of the fallopian tube to form a wide end portion thereof.

이때, 상기 힌지축(5)과 유입구(2a)의 거리인 회전반경(R)은 오일의 경사시유입구(2a)의 끝 부위가 오일 속에 잠길 수 있는 거리임은 물론이다.At this time, the rotation radius (R), which is the distance between the hinge shaft (5) and the inlet (2a) is, of course, the distance that the end portion of the inlet (2a) when the oil is inclined in the oil.

이에 따라, 오일팬(1)내의 오일이 한 쪽으로 쏠리지 않고 수평을 이루는 초기유면(O)시 상기 오일스테이너(2)의 유입구(2a)가 수직하게 직선을 이루면서 오일을 유입시키게 된다.Accordingly, the oil inlet (2a) of the oil stainer (2) is in a vertical straight line when the oil in the oil pan (1) is not horizontal to the side to the horizontal (O) is introduced into the oil.

한편, 차량이 급정거하거나 급 출발하는 경우나 경사로를 주행하는 경우에는 차체의 관성력에 의해 오일이 도면의 좌측이나 우측에서 급격하게 쏠리면서 경사진 경사유면(O')을 형성하면, 이와 같이 경사지게 한 쪽으로 이동되는 오일을 따라 오일스테이너(2)의 유입구(2a)가 힌지축(5)을 매개로 함께 이동되어진다.On the other hand, when the vehicle stops or starts quickly, or when driving on a slope, when the oil is sharply drawn on the left or right side of the drawing due to the inertia force of the vehicle, the inclined slope oil surface O 'is formed. The inlet 2a of the oil stainer 2 is moved together via the hinge shaft 5 along the oil which is moved to the side.

이때, 상기 유입구(2a)에 구비된 오일버켓(6)은 한 쪽으로 이동되는 오일과 함께 이동되는 유입구(2a)의 움직임에 부가되는 힘을 부여 즉, 이동되는 오일의 이동력을 받아 오일의 이동 방향으로 유입구(2a)를 이동시키게 됨은 물론이다.At this time, the oil bucket (6) provided in the inlet (2a) imparts a force added to the movement of the inlet (2a) is moved along with the oil moved to one side, that is, the movement of the oil by receiving the movement force of the moved oil Of course, it moves the inlet (2a) in the direction.

이와 같이, 오일팬(1)내의 오일이 한쪽으로 쏠리더라도 오일스테이너(2)의 유입구(2a)가 오일의 유면을 따라 추종되는 이동을 하여 오일팬(1)내의 공기 중에 노출되지 않게 됨은 물론이다.As such, even if the oil in the oil pan 1 is pulled to one side, the inlet port 2a of the oil stayer 2 moves along the oil level so that the oil pan 1 is not exposed to the air in the oil pan 1. to be.

이상 설명한 바와 같이 본 발명에 의하면, 차량의 주행상태에 따라 오일팬내의 오일이 한 쪽으로 쏠리더라도 오일스테이너의 오일 흡입구가 오일팬 내의 오일속에 항시 잠겨 있도록 하여 오일의 공급이 지속적으로 이루어지므로 각 습동부의 비 정상적인 마모를 방지할 뿐 만 아니라 내구수명도 연장할 수 있는 효과가 있게 된다.As described above, according to the present invention, even if the oil in the oil pan is pulled to one side according to the driving state of the vehicle, the oil intake port of the oil stayer is always locked to the oil in the oil pan so that the oil is continuously supplied to each sliding part. This will not only prevent abnormal wear, but also extend the service life.

또한, 본 발명은 오일을 유입하는 유입구를 오일스테이너와 동일하게 형성하므로 캡과 같은 별도의 부품으로 인한 용접이나 트리밍 작업이 요구되지 않아 조립공정이 단순해지는 효과가 있게됨은 물론이다.In addition, since the present invention is formed in the same inlet for the oil inlet to be the same as the oil stainer, there is no need for welding or trimming operation due to a separate part such as a cap, there is, of course, the effect of simplifying the assembly process.
