본 고안은 차량의 피스톤에 관한 것으로, 특히 피스톤의 외주면에 축방향으로 일정한 간격마다 오일리턴홈을 형성하여 압력다운 및 오일리턴을 유도하여 주므로서 오일소모(LOC)의 저감과 블로우바이을 개선하도록 안출한 차량의 피스톤구조에 관한 것이다.The present invention relates to a piston of a vehicle, and in particular, oil return grooves are formed at regular intervals in the axial direction on the outer circumferential surface of the piston to induce pressure down and oil return, thereby reducing oil consumption (LOC) and improving blow-by. It relates to the piston structure of a vehicle.
일반적으로 피스톤은 4싸이클행정을 위하여 실린더내에서 상,하 왕복운동하도록 되어 있으며, 실린더내벽과의 마찰방지와 원활한 습동을 위하여 피스톤의 외주면에 3개의 오일링이 조립되어 있다.Generally, the piston is designed to reciprocate up and down in the cylinder for four cycle stroke, and three oil rings are assembled on the outer circumferential surface of the piston for preventing friction and smooth sliding with the inner wall of the cylinder.
이때, 오일링은 실린더내벽과의 접촉에 의하여 피스톤의 제 1,2,3랜드와 실린더벽사이에 간극의 형성으로 피스톤의 하강행정시 각 간극사이에서 생성되는 압력의 역전에 의하여 오일이 상승되므로 오일의 소모요인이 되었으며, 또한 입력의 높아짐에 따라 블로우바이가 증가되는 문제점이 있었다.At this time, the oil ring is formed by a gap between the first, second and third lands of the piston and the cylinder wall by contact with the inner wall of the cylinder, so that the oil rises due to the reversal of the pressure generated between the gaps when the piston descends. The oil was a consumable factor, and there was a problem that the blow-by increased as the input was increased.
본 고안은 이러한 종래의 문제점을 해결하고자 하는 것으로, 피스톤의 외주면에 축방향으로 일정한 간격마다 오일리턴홈을 형성하여 압력다운 및 오일리턴을 유도하여 주므로서 오일소모(LOC)의 저감과 블로우바이를 개선하고자 차량의 피스톤구조를 제공하는 데 그목적이 있다.The present invention is to solve this conventional problem, to reduce the oil consumption (LOC) and blow-by by forming an oil return groove at regular intervals in the axial direction on the outer peripheral surface of the piston to induce pressure down and oil return The purpose is to provide a piston structure of a vehicle for improvement.
본 고안은 이러한 목적을 달성하기 위하여, 실린더내벽과의 마찰방지와 원활한 습동을 위하여 피스톤의 외주면에 조립되는 다수개의 오일링과, 최하방의 오일링에서부터 하단까지 피스톤의 외주면에 축방향으로 일정한 간격마다 다수 형성되는 오일리턴홈으로 차량의 피스톤구조를 구성한 것이 본 고안의 특징이다.In order to achieve this object, the present invention provides a plurality of oil rings assembled on the outer circumferential surface of the piston for preventing friction and smooth sliding with the inner wall of the cylinder, and at regular intervals in the axial direction on the outer circumferential surface of the piston from the lower oil ring to the lower end It is a feature of the present invention to constitute a piston structure of a vehicle with a plurality of oil return grooves are formed.
이하 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도면 제1도 내지 제3도는 본 고안의 실시예로서, 실린더(10)내벽과의 마찰방지와 원활한 습동을 위하여 피스톤(20)의 외주면에 조립되는 다수개의 오일링(30)과, 최하방의 오일링(30)에서 부터 하단까지 피스톤(20)의 외주면에 축방향으로 일정한 간격마다 다수 형성되는 오일리턴홈(21)으로 차량의 피스톤구조를 구성한다.1 through 3 are embodiments of the present invention, and a plurality of oil rings 30 and the lowest oil are assembled on the outer circumferential surface of the piston 20 for preventing friction with the inner wall of the cylinder 10 and smooth sliding. The piston structure of the vehicle is composed of a plurality of oil return grooves 21 are formed at regular intervals in the axial direction from the ring 30 to the lower end of the piston 20.
상기 오일링(30)은 3개로 구성되며, 각 오일링(30)이 설치된 피스톤(20)과 실린더(10)의 벽사이에 설정된 간극(x)이 형성된다. 상기 오일링(30)을 지지하도록 피스톤(20)에 설정된 간격마다 제 1,2,3랜드(22)(23)(24)를 형성된다.The oil ring 30 is composed of three, the gap (x) is set between the piston 20 and the wall of the cylinder 10, each oil ring 30 is installed. First, second and third lands 22, 23, 24 are formed at intervals set in the piston 20 to support the oil ring 30.
이와같이 구성된 본 고안은, 피스톤(20)의 상,하왕복운동에 의하여 엔진의 4싸이클행정이 이루어지게 된다.The present invention configured as described above, the four cycle stroke of the engine is made by the up and down reciprocating motion of the piston (20).
이때, 각 오일링(30)의 사이마다 압력이 각각 다른 P1P2,P3의 압력이 발생하게 되는 데, 피스톤(20)의 상승행정시에는 P1P2P3의 압력이 발생하게 되고, 피스톤(20)의 하강시에는 P1P2P3의 압력이 발생하게 된다.At this time, it has a pressure of P 1 P 2 P 3 generated during the rising stroke of the pressure of each of the other P 1 P 2, to which it is of P 3 of the pressure generating piston (20) each between the respective oil ring 30 When the piston 20 descends, pressure of P 1 P 2 P 3 is generated.
따라서 피스톤(20)의 외주면에 형성된 오일리턴홈(21)이 하부의 오일실과 연통되어 있으므로 피스톤(20)의 상승행정 후 하강행정시 압력의 역전발생시 오일리턴홈(21)으로 분산 및 오일실로 배출되도록 하므로서 P3의 압력을 다운시켜 주게 되는 것이며, 압력의 다운으로 피스톤(20)의 상,하강시 압력의 역전을 방지하여 오일의 상승을 억제할 수가 있는 것이다.Therefore, since the oil return groove 21 formed on the outer circumferential surface of the piston 20 communicates with the lower oil chamber, the oil return groove 21 is dispersed and discharged into the oil return groove 21 when the pressure is reversed during the lower stroke after the upward stroke of the piston 20. By lowering the pressure of P 3 , it is possible to prevent the reversal of the pressure during the up and down of the piston 20 due to the decrease in pressure, thereby suppressing the rise of the oil.
그러므로 오일의 상승을 억제하여 주므로서 오일의 소모를 현저하게 줄일 수가 있어 오일의 기능을 충분히 작용하도록 하고, 이로인해 블로우바이의 발생에 따른 오일의 소모도 방지하여 줄 수가 있는 것이다.Therefore, it is possible to significantly reduce the consumption of oil by suppressing the rise of the oil to fully function the function of the oil, thereby preventing the consumption of oil due to the generation of blow-by.
이와같이 본 고안은 피스톤의 외주면에 축방향으로 일정한 간격마다 오일리턴홈을 형성하여 압력다운 및 오일리턴을 유도하여 주므로서 오일소모의 저감과 블로우바이를 개선할 수 있는 효과가 있다.As such, the present invention forms an oil return groove at regular intervals in the axial direction on the outer circumferential surface of the piston to induce pressure down and oil return, thereby reducing oil consumption and improving blow-by.
