Abstract
본 고안은 차량의 커넥팅로드(connecting rod)에 관한 것으로, 보다 상세하게는 피스턴에 체결되는 커넥팅로드의 소단부 중심부가 고속시 가변기능을 갖도록 한 가변 커넥팅로드에 관한 것이다.The present invention relates to a connecting rod (vehicle) of the vehicle, and more particularly to a variable connecting rod such that the central portion of the small end of the connecting rod fastened to the piston has a variable function at high speed.
본 고안은 고속주행시 엔진 RPM의 회전수가 설정치 이상이 될 때 피스턴핀 상단면에 설치된 왁스에 가열된 냉각수를 인가시키고, 이때 왁스의 팽창에 의해 피스턴핀의 하향이동에 의한 피스턴의 상향이동에 의해 피스턴의 상사점 및 하사점을 상향조정하므로서 실린더내의 배기량 면적을 변화시켜 고속주행시에 발생하던 노킹(knocking) 현상을 방지할 수 있게 되며, 엔진 출력을 크게 향상시킬 수 있는 효과가 있다.The present invention applies the heated cooling water to the wax installed on the top surface of the piston pin when the rotation speed of the engine RPM is higher than the set value at high speed, and at this time, the piston is moved by upward movement of the piston by downward movement of the piston pin by expansion of the wax. By adjusting the top dead center and the bottom dead center of the engine, it is possible to prevent the knocking phenomenon that occurs during high-speed driving by changing the displacement of the displacement in the cylinder, and greatly improve the engine output.

본 고안은 차량의 커넥팅로드(connecting rod)에 관한 것으로, 보다 상세하게는 피스턴에 체결되는 커넥팅로드의 소단부 중심부가 고속시 가변기능을 갖도록 한 가변 커넥팅로드에 관한 것이다.The present invention relates to a connecting rod (vehicle) of the vehicle, and more particularly to a variable connecting rod such that the central portion of the small end of the connecting rod fastened to the piston has a variable function at high speed.
일반적으로 자동차의 엔진기관을 이루고 있는 실린더는 피스턴 및 커넥팅로드등과 함께 구성되는, 피스턴의 직선왕복 운동은 커넥팅로드를 통해 크랭크축의 회전운동으로 전환시키고, 실린더내에서 상, 하 왕복운동을 하게 된다.In general, the cylinders that make up the engine of a car are composed of pistons and connecting rods, and the linear reciprocating motion of the pistons is converted to the rotational movement of the crankshaft through the connecting rods, and the cylinder moves up and down. .
또한 차량의 배기량은 상기 실린더내에서 상, 하 왕복운동하는 피스턴이 상사점과 하사점에 있을때의 움직인 거리에 비례하게 된다.In addition, the displacement of the vehicle is proportional to the distance traveled when the piston moving up and down in the cylinder is at the top dead center and the bottom dead center.
즉, 차량의 배기량은 피스턴이 상사점에 있을때와 하사점에 있을때의 움직인 거리에 해당하는 실린더의 내부에 흡입되는 혼합공기량에 해당되는 것이다.That is, the displacement of the vehicle corresponds to the amount of mixed air sucked into the cylinder corresponding to the distance traveled when the piston is at the top dead center and the bottom dead center.
따라서 피스턴의 상사점과 하사점의 위치를 변화시키면 차량의 배기량도 변하게 된다.Therefore, if the position of the top dead center and the bottom dead center of the piston is changed, the displacement of the vehicle is also changed.
또한 차량의 고속주행시 엔진과열에 의해 흡입되는 혼합공기의 온도가 높게되면 시린더내에서 일종의 금속성 폭음인 노킹현상이 발생하게 되는 문제점이 있다.In addition, when the temperature of the mixed air sucked by the engine overheating at high speed of the vehicle is high, there is a problem that knocking phenomenon, which is a kind of metallic binge, occurs in the cylinder.
본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로 본 고안의 목적은 차량의 고속주행시 엔진출력을 높이면서 노킹현상을 방지할 수 있는 장치를 제공하는데 있다.The present invention has been made to solve the above problems is an object of the present invention to provide a device that can prevent the knocking phenomenon while increasing the engine output during high-speed driving of the vehicle.
상기 목적을 달성하기 위하여 본 고안은 커넥팅로드의 소단부에 삽입되며 상단면이 평탄(plane)을 이루는 피스턴핀과, 상기 피스턴핀의 상단면에 착설되며 인가되는 온도에 의해 체적이 변하는 특성을 갖는 왁스와, 상기 왁스에 연소실을 냉각시킨 냉각수가 인가되도록 커넥팅로드의 내부에 구비된 냉각수 유입로와, 컴퓨터부(ECU)의 제어로 실린더블럭의 냉각수가 크랭크축의 저널을 통해 커넥팅로드의 냉각수 유입로로 냉각수가 인가되도록 하는 솔레노이드 밸브와 평상시 피스턴핀이 상단면에 밀착되도록 가압하는 플런저로 구성된다.In order to achieve the above object, the present invention is inserted into a small end of the connecting rod and has a characteristic that the volume is changed by a temperature applied to the top surface of the piston rod and the top surface of which is formed a plane (plane) and applied The cooling water inlet path provided inside the connecting rod so that wax and cooling water cooling the combustion chamber is applied to the wax, and the cooling water inflow path of the connecting rod through the journal of the crankshaft under the control of the computer unit ECU. The furnace consists of a solenoid valve for applying coolant and a plunger for pressurizing the piston pin to be in close contact with the upper surface.
이하 첨부된 도면을 참조하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도를 참조하여 설명하면, 피스턴의 핀보스(도시안됨)와 커넥팅로드(10)의 소단부(12)를 상호 체결시키는 피스턴핀(20)은 상단면을 평탄(plane)하게 형성시키고, 상기 피스턴핀(80) 상단면에는 열을 받으면 팽창하는 특성을 갖는 왁스(30)를 착설시키며, 피스턴핀 하단면에는 리턴스프링으로 된 플런저(plunger)(40)를 착설시킨다.Referring to FIG. 1, the piston pin 20 connecting the pin boss (not shown) of the piston and the small end 12 of the connecting rod 10 forms a flat top surface. On the top surface of the piston pin 80, a wax 30 having a property of expanding upon being heated is installed, and a plunger 40 made of a return spring is installed on the bottom surface of the piston pin.
또한 커넥팅로드(10) 내부에는 크랭크축(50)의 저널을 통해 인가되는 냉각수가 왁스(30)에 유입되도록 냉각수유입로(14)를 형성시키고, 실린더블럭(60)에는 솔레노이드밸브(70)를 착설시킨다.In addition, a cooling water inflow path 14 is formed in the connecting rod 10 such that the cooling water applied through the journal of the crankshaft 50 flows into the wax 30, and the solenoid valve 70 is provided in the cylinder block 60. Install it.
상기 솔레노이드밸브(70)에는 컴퓨터부(ECU)(72)가 접속되며, 상기 컴퓨터부(72)는 RPM이 메모리된 양과 일치하였을 때 솔레노이드밸브(70)를 열어 실린더블럭(60)을 냉각시킨 냉각수가 크랭크축(50)의 저널을 통해 커넥팅로드(10)에 유입되고, 커넥팅로드(10)에 유입된 냉각수는 냉각수유입로(14)를 통해 왁수(30)에 인가된다.A computer unit (ECU) 72 is connected to the solenoid valve 70, and the computer unit 72 opens the solenoid valve 70 to cool the cylinder block 60 when the RPM matches the stored amount. Is introduced into the connecting rod 10 through the journal of the crankshaft 50, the cooling water introduced into the connecting rod 10 is applied to the wax water 30 through the cooling water inlet (14).
이때 냉각수는 실린더블럭(60)의 연소실 주위를 냉각시켜 고온의 상태로 변환된 상태가 되어 왁스(30)에 고온의 열을 인가하게 되므로 왁스(30)가 팽창하게 된다.At this time, the cooling water cools around the combustion chamber of the cylinder block 60 and is converted into a high temperature state, thereby applying high temperature heat to the wax 30, thereby expanding the wax 30.
일실시예를 통해 상세히 설명하면, 차량이 고속주행을 하여 RPM 회전수가 설정된 값 이상이 되면 컴퓨터부(72)에서 이를 감지하여 솔레노이드밸브(70)를 오픈(open)시키게 된다.In detail through an embodiment, when the vehicle is driving at a high speed and the RPM rotation speed is more than the set value, the computer unit 72 detects this and opens the solenoid valve 70.
상기 솔레노이드밸브(70)가 오픈되면 냉각수가 크랭크축의 저널을 통해 커넥팅로드(10)의 냉각수유입로(14)로 유입되고, 이때 냉각수는 냉각수유입로(14)를 거쳐 피스턴핀(80) 상단부에 착설된 왁스(30)에 인가되어 왁스를 팽창시키게 된다.When the solenoid valve 70 is opened, the coolant flows into the coolant inlet 14 of the connecting rod 10 through the journal of the crankshaft, and the coolant passes through the coolant inlet 14 to the upper portion of the piston pin 80. It is applied to the installed wax 30 to expand the wax.
상기 왁스(30)가 팽창되면 왁스가 피스턴핀(80)을 지지하고 있던 플런저(40)의 압력을 이기고 피스턴핀을 하향으로 밀게 된다.When the wax 30 is expanded, the wax overcomes the pressure of the plunger 40 supporting the piston pin 80 and pushes the piston pin downward.
상기 피스턴핀(80)이 왁스(30)에 의해 하향이동하게 되면 반대로 피스턴이 피스턴핀을 중심으로 상향이동하게 되어 피스턴의 상사점 및 하사점의 위치가 상향조정 되게 된다.When the piston pin 80 is moved downward by the wax 30, the piston moves upwardly around the piston pin, and the positions of the top dead center and the bottom dead center of the piston are upwardly adjusted.
이상 설명에서 알 수 있는 바와같이, 본 고안은 고속주행시 엔진 RPM의 회전수가 설정치 이상이 될 때 피스턴핀 상단면에 설치된 왁스에 가열된 냉각수를 인가시키고, 이때 왁스의 팽창에 의해 피스턴핀의 하향이동에 의한 피스턴의 상향이동에 의해 피스턴의 상사점 및 하사점을 상향조정하므로서 실린더내의 배기량 면적을 변화시켜 고속주행시에 발생하던 노킹(knocking) 현상을 방지할 수 있게 되며, 엔진 출력을 크게 향상시킬 수 있는 효과가 있다.As can be seen from the above description, the present invention applies the heated coolant to the wax installed on the upper surface of the piston pin when the rotational speed of the engine RPM is higher than the set value at high speed, and at this time, the downward movement of the piston pin by expansion of the wax By adjusting the upper and lower dead centers of the pistons by changing the upward movement of the pistons, it is possible to prevent the knocking phenomenon that occurs during high-speed driving by changing the displacement of the cylinder in the cylinder, and greatly improve the engine output. It has an effect.
