Abstract
컨넥팅 로드(52)와 피스톤(51)을 피스톤 핀(54)으로 연결함은 조립이 어려워 생산성이 저하될 뿐만 아니라 피스톤 핀(54)과 피스톤(51) 그리고 컨넥팅 로드(52)와의 사이에서 소음이 발생되고 피스톤 핀(54)에 모든 힘이 인가되기 때문에 엔진에 과부하가 걸릴 경우 원통형상인 피스톤 핀(54)이 파손되는 경우를 방지하기 위하여, 피스톤(51)과 컨넥팅 로드(52)가 직접 연결 수단에 의해 연결되어 피스톤(51)의 폭발력이 컨넥팅 로드(52)에 직접 전달되도록 구성함으로써 피스톤(51)과 컨넥팅 로드(52)의 조립을 단순화하고 소음을 방지할 수 있게 된다.Connecting the connecting rod 52 and the piston 51 with the piston pin 54 is difficult to assemble, which leads to a decrease in productivity as well as between the piston pin 54 and the piston 51 and the connecting rod 52. Since the noise is generated and all the force is applied to the piston pin 54, the piston 51 and the connecting rod 52 are connected to prevent the cylindrical piston pin 54 from being broken when the engine is overloaded. By connecting by direct connection means configured to transmit the explosive force of the piston 51 directly to the connecting rod 52 it is possible to simplify the assembly of the piston 51 and the connecting rod 52 and to prevent noise.

일반적으로, 자동차는 차체와 새시로 구성되는 바, 상기한 새시는 엔진, 동력 전달 장치, 스티어링 장치, 서스펜션등으로 구성되어 있고, 상기한 차체가 이를 감싸고 외면을 이루고 있다.In general, a car is composed of a body and a chassis, the chassis is composed of an engine, a power transmission device, a steering device, a suspension, etc., the body is wrapped around it and forms an outer surface.
여기서, 상기한 엔진은 실질적으로 자동차의 동력을 발생시키는 부품으로써 OHV(Over Head Valve)형과, OHC(Over Head Camshaft)으로 대별되지만 현재는 OHC형의 엔진이 많이 사용된다.Here, the engine is a part that substantially generates the power of the vehicle, but is roughly divided into an OHV (Over Head Valve) type and an OHC (Over Head Camshaft), but many engines of the OHC type are currently used.
상기한 엔진의 일반적인 구성은 엔진 블럭 내부에 형성된 다수의 연소실에 다수의 피스톤 핀이 결합되어 있는 피스톤을 삽입함과 아울러 이를 실린더 헤드로 밀폐시키고, 상기한 피스톤에는 크랭크 축에 연결되어 있는 컨넥팅 로드가 연결되어 있는 상태로 구성됨으로써 크랭크 축을 통해 연소실의 폭발력을 구동바퀴에 전달하게 되는 것이다.The general configuration of the engine includes inserting a piston having a plurality of piston pins coupled to a plurality of combustion chambers formed inside the engine block and sealing it with a cylinder head, wherein the connecting rod is connected to a crank shaft. Is configured to be connected to transmit the explosive force of the combustion chamber to the drive wheel through the crankshaft.
여기서, 상기한 피스톤과 컨넥팅 로드는 제4도에 도시된 바와 같이 다수의 피스톤 링(50)이 결합되어 있는 피스톤(51)과, 상기한 피스톤(51)에 삽입됨과 아울러 크랭크 축(미 도시)이 연결되는 컨넥팅 로드(52)가 피스톤(51)과 컨넥팅 로드(52)에 형성된 결합공(53)을 통해 피스톤 핀(54)으로 연결되어 있다.Here, the piston and the connecting rod is inserted into the piston 51 and the piston 51 to which the plurality of piston rings 50 are coupled as shown in FIG. Connecting rod 52 is connected to the piston pin 54 through the coupling hole 53 formed in the piston 51 and the connecting rod 52.
즉, 실질적으로 피스톤(51)과 컨넥팅 로드(52)는 피스톤 핀(54)에 의해 연결되는 바, 상기한 피스톤 핀(54)은 피스톤(51)의 왕복 운동과 컨넥팅 로드(52)의 회전, 왕복 운동에 발생되는 압력을 극복할 정도의 강도를 갖고 있어야 된다.That is, substantially the piston 51 and the connecting rod 52 is connected by the piston pin 54, the piston pin 54 is the reciprocating motion of the piston 51 and the connecting rod 52 It must be strong enough to overcome the pressure generated during rotation and reciprocation.
물론, 상기한 피스톤 핀(54)의 결합에서 피스톤 핀(54)과 피스톤(51) 그리고 컨넥팅 로드(52)에는 마찰이 많이 발생되기 때문에 이의 마찰을 최소화할 수 있도록 여러 가지의 방법이 개발되어 있다.Of course, since a lot of friction occurs in the piston pin 54, the piston 51 and the connecting rod 52 in the combination of the piston pin 54, various methods have been developed to minimize the friction thereof. have.
그러나, 상기한 바와 같이 컨넥팅 로드(52)와 피스톤(51)을 피스톤 핀(54)으로 연결함은 조립이 어려워 생산성이 저하될 뿐만 아니라 피스톤 핀(54)과 피스톤(51) 그리고 컨넥팅 로드(52)와의 사이에서 소음이 발생되는 문제점이 있다.However, as described above, connecting the connecting rod 52 and the piston 51 with the piston pin 54 is difficult to assemble, thereby reducing productivity, as well as the piston pin 54 and the piston 51 and the connecting rod. There is a problem that noise is generated between 52 and.
또한, 피스톤 핀(54)에 모든 힘이 인가되기 때문에 엔진에 과부하가 걸릴 경우 원통형상인 피스톤 핀(54)이 파손되는 경우가 있다.Moreover, since all the force is applied to the piston pin 54, when the engine is overloaded, the cylindrical piston pin 54 may be damaged.
따라서, 본 고안의 목적은 상기한 문제점을 해결하기 위한 것으로서, 피스톤과 컨넥팅 로드와의 조립성을 향상시킬 뿐만 아니라 피스톤과 컨넥팅 로드에서 발생되는 소음을 최소화할 수 있는 피스톤과 컨넥팅 로드 연결 구조를 제공함에 있다.Accordingly, an object of the present invention is to solve the above problems, and improves the assemblability of the piston and the connecting rod as well as connecting the piston and the connecting rod to minimize the noise generated from the piston and the connecting rod. In providing a structure.
상기한 목적을 실현하기 위하여 본 고안은 피스톤과 컨넥팅 로드가 직접 연결수단에 의해 연결되어 피스톤의 폭발력이 컨넥팅 로드에 직접 전달되도록 구성함을 특징으로 한다.In order to realize the above object, the present invention is characterized in that the piston and the connecting rod are connected by a direct connection means so that the explosive force of the piston is directly transmitted to the connecting rod.
이하, 첨부 도면을 참조하여 본 고안의 상세한 일실시예를 설명하면 다음과 같다.Hereinafter, a detailed embodiment of the present invention with reference to the accompanying drawings.
제1도와 제2도는 본 고안에 따른 피스톤과 컨넥팅 로드 연결 구조를 도시한 분해 사시도와 조립 단면도로서, 피스톤(51)과 컨넥팅 로드(52)가 직접 연결수단에 의해 연결되어 피스톤(51)의 폭발력이 컨넥팅 로드(52)에 직접 전달되도록 구성되어 있다.1 and 2 are exploded perspective view and assembly cross-sectional view showing a piston and connecting rod connecting structure according to the present invention, the piston 51 and the connecting rod 52 is connected by a direct connection means piston 51 The explosive force of is configured to be transmitted directly to the connecting rod (52).
상기한 직접 연결 수단은 컨넥팅 로드(52)의 일측 즉, 피스톤(51)과 연결되는 부분에 형성된 원형의 걸림 회전부(1)와, 상기한 걸림 회전부(1)와 대응되도록 피스톤(51)의 내측에 일체로 형성된 걸림부(2)와, 상기한 걸림부(2)와 걸림 회전부(1)의 결합시 이의 좌우 유동을 방지하기 위해 피스톤(51)에 형성된 걸림부(2)에 볼트(3)등으로 결합되는 2개의 고정부재(4)로 구성되어 있다.The direct connection means includes a circular locking rotary part 1 formed at one side of the connecting rod 52, that is, a part connected to the piston 51, and the piston 51 so as to correspond to the locking rotary part 1. In order to prevent the left and right flow of the locking portion (2) formed integrally with the inside, and the locking portion (2) and the locking rotation part (1), the bolt (3) on the locking portion (2) formed on the piston (51) It consists of two fixing members (4) that are coupled to).
여기서, 상기한 걸림 회전부(1)는 컨넥팅 로드(52) 부분이 아닌 부분이 깎여 반원형상으로 형성되어 있고, 걸림부(2)는 상기한 걸림 회전부(1)가 측면에서 슬라이드 삽입되어 외부로 이탈되지 않고 내부에서 걸릴 수 있도록 반원이상의 형상으로 가공되어 있다.Here, the engaging rotation part 1 is formed in a semi-circular shape by cutting a portion other than the connecting rod 52 part, and the engaging part 2 is inserted into the engaging part by sliding the engaging part 1 from the side to the outside. It is processed into a shape of semi-circle or more so that it can be caught inside without being separated.
즉, 걸림 회전부(1)의 반경보다 D만큼 작게 입구(5)가 형성되어 있는 바, 이로 인하여 걸림 회전부(1)가 외부로 이탈될 수 없는 것이다.That is, the inlet 5 is formed by D smaller than the radius of the locking rotary unit 1, and thus the locking rotary unit 1 cannot be separated outward.
상기한 바와 같은 본 고안의 작용 효과를 설명하면 반원 형상으로 걸림 회전부(1)가 가공되어 있는 컨넥팅 로드(52)를 피스톤(51)의 걸림부(2) 측면에서 슬라이드시키면서 끼워 결합시킨다.When explaining the operation and effect of the present invention as described above, the connecting rod 52 is processed in the semi-circular shape of the locking rod (1) while sliding in the engaging portion (2) side of the piston 51 to engage.
이때, 상기한 걸림 회전부(1)는 걸림부(2)에 삽입되어 수평 이동은 가능하지만 수직 이동 즉, 피스톤(51)의 왕복운동 방향으로의 이탈은 불가능하게 된다.At this time, the locking rotation part 1 is inserted into the locking part 2, but the horizontal movement is possible, but the vertical movement, that is, the separation in the reciprocating direction of the piston 51 is impossible.
걸림 회전부(1)를 걸림부(2)에 삽입시킨 후 2개로 분리되어 있는 고정부재(4)를 컨넥팅 로드(52)를 중심으로 결합시켜 볼트(3)로 고정시키면 제3도에 도시된 바와 같이 컨넥팅 로드(52)를 사이에 두고 고정 부재(4)가 이를 감싸고 있기 때문에 컨넥팅 로드(52)가 수평 이동 불가능하게 되는 것이다.After inserting the locking rotating part (1) to the locking part (2), the fixing member (4), which is separated into two, is coupled to the connecting rod (52) to fix it with the bolt (3) as shown in FIG. As described above, since the fixing member 4 surrounds the connecting rod 52 therebetween, the connecting rod 52 is not movable horizontally.
상기한 바와 같이 컨넥팅 로드(52)의 걸림회전부(1)와 피스톤(51)의 걸림부(2)가 직접 연결되어 있으며 피스톤(51)의 왕복운동과, 컨넥팅 로드(52)의 회전운동에 따른 부하가 컨넥팅 로드(52)와 피스톤(51)에 분산됨으로써 그 회전부위가 보다 원활하게 운동 가능하게 된다.As described above, the engaging rotation part 1 of the connecting rod 52 and the engaging part 2 of the piston 51 are directly connected, and the reciprocating motion of the piston 51 and the rotational motion of the connecting rod 52 are made. The load is distributed to the connecting rod 52 and the piston 51, so that the rotating portion can be more smoothly moved.
여기서, 상기한 걸림 회전부(1)와 걸림부(2)의 사이에 오일리스 베어링등과 같이 마찰을 극소화시킬 수 있는 부재 또는 윤활제를 삽입하면 보다 원활하게 운동되고 소음을 극소화시킬 수 있게 된다.Here, inserting a member or a lubricant capable of minimizing friction, such as an oilless bearing, between the engaging rotation part 1 and the engaging part 2 enables smooth movement and minimizes noise.
이상과 같이 본 고안은 피스톤과 컨넥팅 로드를 직접 연결 수단을 통해 직접 연결하여 소음을 방지함과 아울러 조립을 단순화하여 생산성을 향상시킬 수 있는 잇점이 있는 것이다.As described above, the present invention is advantageous in that the piston and the connecting rod are directly connected through a direct connection means to prevent noise and simplify the assembly to improve productivity.
