Description
본원 발명은 엔진의 피스톤의 왕복 구동는 충격흡수장치에 관한 것이다.The present invention relates to a shock absorbing device for reciprocating driving of a piston of an engine.
엔진은 연소실로 유입된 혼합기를 점화하여 그때의 폭발력으로 피스톤을 왕복 구동하고 이를 크랭크에 의해 회전 운동으로 변환하게 된다.The engine ignites the mixer introduced into the combustion chamber, drives the piston reciprocally by the explosive force at that time, and converts it into rotational motion by the crank.
엔진의 연소실 내에서 폭발이 일어나면 피스톤이 고속으로 왕복 운동하게 되며 이때의 폭발력이 피스톤과 실친더블록면에 전달되어지게 되나 종래의 경우 워터재킷이외에는 충격 및 진동 소음을 저감할 수 있는 별도의 차단장치가 구비되어 있지 아니하여 소음이 그대로 차실내로 유입되어 안락한 운행을 방해하고 엔진의 내구성을 떨어뜨리는 문제점이 있어 왔다.When the explosion occurs in the combustion chamber of the engine, the piston reciprocates at a high speed and the explosive force is transmitted to the piston and the cylinder block surface. In the conventional case, however, a separate interrupting device There is a problem that noise is introduced into the passenger compartment of the vehicle as it is, which hinders comfortable driving and lowers the durability of the engine.

이하 본 발명의 실시예를 첨부한 도면을 창조하며 상술한다.BRIEF DESCRIPTION OF THE DRAWINGS Fig.
도 1은 본 발명에 의한 엔진의 충격흡수장치를 나타내는 도면으로 도면에 있어서 부호 1은 실린더블록이며, 부호 2는 실린더 보어(3)를 따라 왕복 운동하는 피스톤이다.1 is a view showing a shock absorbing device for an engine according to the present invention. In the figure, reference numeral 1 denotes a cylinder block and reference numeral 2 denotes a piston reciprocating along the cylinder bore 3.
상기 실린더블록(2)에는 실린더 보어(3)에 연통하는 구멍(4)이 수평방향으로 천공되며 구멍(4)의 후방에는 챔버(5)가 형성되어 있다.A hole 4 communicating with the cylinder bore 3 is horizontally drilled in the cylinder block 2 and a chamber 5 is formed behind the hole 4.
상기 구멍(4)에는 구멍(4)을 따라 움직임이 허용되는 볼(6)이 수용되어 있으며 그 볼(6)은 챔버(5)내에 설치되는 액츄에이터(7)의 플런저(8)선단에 기지되고 있다.The hole 4 receives a ball 6 allowed to move along the hole 4 and the ball 6 is fixed to the tip of the plunger 8 of the actuator 7 installed in the chamber 5 have.
상기 액츄에이터(7)는 전기적 수단에 의해 작동하는 솔레노이드로서 RPM 게이지(9)로부터 측정되는 엔진의 회전수 정보에 따라 전자제어장치(10)에 의해 작동이 제어 된다.The actuator 7 is a solenoid operated by an electric means and its operation is controlled by the electronic control unit 10 in accordance with the information on the number of revolutions of the engine measured from the RPM gauge 9. [
이와같이 구성된 본 발명은 엔진의 연소실에 도입된 혼합기가 점화 폭발되어 피스톤(2)이 상하 운동하게 되면 RPM 게이지(9)를 통해 엔진의 회전수 정보가 전자제어장치(10)에 인가되어지게 되며 엔진의 회전수 정보에 비례하여 액츄에이터(7)의 플런저(8)를 후퇴시켜 폭발시의 충격파에 의해 구멍(4)을 통해 작용하는 압력이 볼(6)을 움직여 충격 및 진동을 감쇄하게 되는 것비다. 여기서 미설명부호(11)은 프런저(6)를 복귀시키는 탄발 스프링이다.When the mixer introduced into the combustion chamber of the engine is ignited and exploded and the piston 2 moves up and down, information on the number of revolutions of the engine is applied to the electronic control unit 10 through the RPM gauge 9, The plunger 8 of the actuator 7 is retracted in proportion to the rotation number information of the ball 7. The pressure acting through the hole 4 by the shock wave at the time of explosion moves the ball 6 to attenuate impact and vibration. . Here, the reference numeral 11 is a spring for returning the plunger 6.
이상과 같은 본원 발명에 의한 엔진의 충격 흡수장치에 의하면 실린더 보어에 연통하는 구멍과 챔버를 실린더블록에 형성하고 구멍속에 움직임이 허용되는 볼을 내장한 후 엔진의 최전수 정보에 따라 작동하는 액츄에이터의 플런지가 그 볼을 지지토록 하므로써 엔진의 회전수에 따라 플런저를 후퇴시키도록 제어하AM로써 구멍 속의 볼을 움직여 폭발시의 충격파를 흡수 완화하여 감쇄하게 되므로써 엔진의 소음을 저감하고 내구성을 증대시키는 효과가 있다.According to the shock absorbing device for an engine according to the present invention as described above, the hole communicating with the cylinder bore and the actuator formed in the cylinder block in the cylinder block and incorporating a ball allowed to move in the hole, As the plunger supports the ball, it controls the plunger to move backward according to the number of revolutions of the engine. By moving the ball in the hole by AM, the shock wave at the explosion is absorbed and attenuated to reduce the noise of the engine and increase the durability It is effective.
