1번 실린더에 의한 럼블링소음제거장치Rumbling noise removing device by 1 cylinder

본 발명은 엔진 럼블링 소음(rumbling noise)에 가장 큰 영향을 주는 요인인 엔진 1번실린더의 연소압력에 의한 진동소음을 억제하는 장치에 관한 것으로서, 더욱 구체적으로는 1번 실린더가 폭발행정을 할 때 크랭크축의 선단에 압력을 가하여 크랭크축의 진동을 방지함으로써 럼블링소음을 방지하는 1번 실린더에 의한 럼블링소음제거장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for suppressing vibration noise caused by combustion pressure of an engine No. 1 cylinder, which is a factor that has the greatest influence on engine rumbling noise. The present invention relates to a rumbling noise removing device by cylinder 1 that prevents rumbling noise by applying pressure to the tip of the crankshaft to prevent vibration of the crankshaft.

엔진은 실린더내에서 피스톤이 상하왕복운동을 함으로써 구동을 하는 것이고 또한 피스톤이 상하왕복운동을 하기 위해서는 실린더내에서 연소작용이 이루어져야 한다.The engine is driven by the piston reciprocating up and down in the cylinder, and the combustion action must be performed in the cylinder in order for the piston to reciprocate up and down.

피스톤은 4행정기관인 경우에는 흡입행정, 압축행정, 폭발행정, 배기행정을 반복하면서 상하왕복운동을 하는 것이다. 피스톤이 상하왕복운동을 하면 크랭크축이 회전운동을 한다.The piston is a four-stroke engine that moves up and down while repeating the suction stroke, compression stroke, explosion stroke, and exhaust stroke. When the piston moves up and down, the crankshaft rotates.

도 1은 상기와 같은 엔진의 개략 단면도이다.1 is a schematic cross-sectional view of such an engine.

크랭크축(1)의 선단부에는 오일펌프, 캠축등을 구동하기 위한 풀리(3)가 설치되어 있고, 크랭크축(1)의 후단부에는 안정된 회전을 위한 플라이휠(4)이 설치되어 있다. 실린더가 형성되어 있는 실린더블럭(2)에 크랭크축(1)이 설치된다.The front end of the crankshaft 1 is provided with a pulley 3 for driving an oil pump, a camshaft, and the like, and the flywheel 4 for stable rotation is provided at the rear end of the crankshaft 1. The crankshaft 1 is provided in the cylinder block 2 in which the cylinder is formed.

피스톤(미도시)은 상기 실린더내에서 왕복운동을 하는데, 폭발행정시에 폭발력에 의하여 크랭크축(1)에 큰 힘을 가한다. 이 힘에 의해서 도 1에서 점선으로 표시된 바와 같이 실린더블럭(2)의 외부로 뻗어 있는 부분의 크랭크축(1)이 휘면서 진동을 하게 되고 그에 따라서 실린더블럭(2)도 변형을 일으키게 된다.A piston (not shown) reciprocates in the cylinder, and applies a large force to the crankshaft 1 by the explosive force during the explosion stroke. As a result of this force, the crankshaft 1 of the portion extending outwardly of the cylinder block 2 is bent and vibrated as indicated by a dotted line in FIG. 1, and thus the cylinder block 2 also causes deformation.

이 진동이 소음을 유발하여 럼블링소음의 주요한 원인이 되고 있다. 자동차에 있어서 진동소음은 운전자의 컨디션에 중요한 역할을 하므로 가능하면 제거를 하는 것이 바람직하다.This vibration causes noise and is a major cause of rumble noise. In a car, vibration noise plays an important role in the driver's condition, so it is desirable to remove it if possible.

그러나 종래의 엔진에는 전술한 1번 실린더에 의한 럼블링소음제거수단이 구비되지 않아 운전자에게 짜증과 피곤함을 느끼게 하고 또한 차량수명을 단축시키고 있는 문제점이 있었다.However, the conventional engine is not provided with the above-described rubbing noise removing means by the first cylinder, there is a problem that makes the driver feel irritable and tired and also shorten the vehicle life.

본 발명은 전술한 종래 자동차의 문제점을 해결하기 위해서 안출된 것으로서, 본 발명의 목적은 1번 실린더의 연소압력, 즉 1번피스톤의 폭발행정시 받는 힘에 의하여 크랭크축이 진동하는 현상을 방지하고 그에 따라 림블링소음도 제거하는 엔진의 1번 실린더에 의한 럼블링소음제거장치를 제공하는데 있다.The present invention has been made to solve the above problems of the conventional vehicle, the object of the present invention is to prevent the crankshaft from vibrating due to the combustion pressure of the first cylinder, that is, the force received during the explosion stroke of the first piston Accordingly, to provide a rumbling noise removing device by the first cylinder of the engine also removes rimbling noise.

상기 목적을 달성하기 위한 본 발명의 1번 실린더에 의한 럼블링소음제거장치는 크랭크축의 선단부상면에 설치되는 피에조재료, 상기 피에조재료와 크랭크축사이에 설치된 베어링, 상기 피에조재료의 상부를 고정하는 고정부, 상기 피에조재료에 전원을 인가하는 릴레이부, 그리고 1번실린더의 폭발행정시 상기 릴레이부를 제어하여 피에조재료로 전원을 인가토록 하는 ECU를 포함하는 것을 특징으로 한다.Rumble noise reduction device according to the first cylinder of the present invention for achieving the above object is a piezo material installed on the top end surface of the crankshaft, a bearing provided between the piezo material and the crankshaft, the fixing portion for fixing the upper portion of the piezo material It includes a relay unit for applying power to the piezoelectric material, and ECU to control the relay unit in the explosion stroke of the first cylinder to apply power to the piezoelectric material.

이하 첨부된 도면을 참조하여 본 발명의 1번 실린더에 의한 럼블링소음제거장치를 보다 상세히 설명하면 다음과 같다.With reference to the accompanying drawings, the rubbing noise removing device according to the first cylinder of the present invention in more detail as follows.

도 2는 본 발명의 1번 실린더에 의한 럼블링소음제거장치의 구성도이고, 도 3은 도 2에서 A-A선의 단면도이다.Figure 2 is a block diagram of a rubbing noise removing device according to the first cylinder of the present invention, Figure 3 is a cross-sectional view of the line A-A in FIG.

도시된 바와 같이 본 발명의 럼블링소음제거장치는 크랭크축(1)의 선단부상면에 설치되는 피에조(piezo)재료(10), 상기 피에조재료(10)와 크랭크축(1)사이에 설치된 베어링(11), 상기 피에조재료(10)의 상부를 고정하는 고정부(12), 상기 피에조재료(10)에 전원을 인가하는 릴레이부(13), 그리고 1번실린더의 폭발행정시 상기 릴레이부(13)를 제어하여 피에조재료(10)로 전원을 인가토록 하는 ECU(14)를 포함한다.As shown, the rumbling noise removing device of the present invention includes a piezo material 10 installed on the top end surface of the crank shaft 1, and a bearing provided between the piezo material 10 and the crank shaft 1 ( 11), the fixing part 12 for fixing the upper portion of the piezo material 10, the relay unit 13 for applying power to the piezo material 10, and the relay unit 13 during the explosion stroke of the first cylinder ) And an ECU 14 for applying power to the piezoelectric material 10.

상기 피에조재료(10)는 압력을 받으면 전기를 발생하고 반대로 전기를 인가하면 압력을 발생하는 특수한 재료로서 종래 널리 알려진 것이므로 이에 대한 구체적인 설명을 생략하기로 한다.The piezoelectric material 10 generates electricity when the pressure is applied, and since the piezoelectric material 10 is known as a special material that generates pressure when the electricity is applied, a detailed description thereof will be omitted.

베어링(11)로서는 로울러, 볼 등이 이용될수 있다. 그리고 고정부(12)는 상기 피에조재료(10)가 압력을 발생할 때 그 압력이 크랭크축(1)에 가해지도록 하는 역할을 하는 것이다.As the bearing 11, a roller, a ball, or the like can be used. In addition, the fixing part 12 serves to apply the pressure to the crankshaft 1 when the piezoelectric material 10 generates pressure.

상기와 같은 본 발명의 1번 실린더에 의한 럼블링소음제거장의 작용을 설명한다.The operation of the rumbling noise removing field by the first cylinder of the present invention as described above will be described.

엔진이 시동되면 실린더에서의 연소작용으로 인하여 피스톤이 왕복운동을 하고 크랭크축이 회전한다.When the engine starts, the piston reciprocates and the crankshaft rotates due to combustion in the cylinder.

이 때 1번실린더의 연소작용시, 즉 1번 피스톤의 폭발행정시에는그 폭발력이 크게 작용하여 크랭크축(1)의 선단부를 휘게 하는 힘이 전달되지만 본 발명은 1번 실린더의 연소작용시에 피에조재료(10)에 전원을 인가하여 피에조재료(10)로 하여금 압력을 발생하도록 되어 있다. 따라서 크랭크축(10)의 선단부가 상향으로 휠려고하는 힘은 피에조재료(10)에 의하여 상충되어 크랭크축(1)의 선단부를 휘지 않게 되며 그에 따라서 크랭크축(1)의 선단부에서 진동, 소음이 일어나지 않게 된다.At this time, during the combustion action of the cylinder 1, that is, during the explosion stroke of the piston 1, the explosive force is largely applied to the bending force of the front end of the crankshaft (1). Power is applied to the piezoelectric material 10 to cause the piezoelectric material 10 to generate pressure. Therefore, the force that the front end of the crankshaft 10 tries to bend upward is conflicted by the piezo material 10 so that the front end of the crankshaft 1 is not bent, and thus vibration and noise are generated at the front end of the crankshaft 1. It won't happen.

그리고 피에조재료(10)에 전원을 인가토록 제어하는 ECU(14)는 크랭크각센서 등 각종 센서로 부터 1번실린더가 연소작용을 하는지, 즉 1번실린더가 폭발행정인지를 감지할수 있다. ECU(10)는 1번 실린더의 연소작용시, 즉 1번 피스톤의 폭발행정시에 릴레이부(13)를 제어하여 전원이 피에조재료(10)에 인가되도록 한다.In addition, the ECU 14 controlling the power supply to the piezoelectric material 10 may detect whether the first cylinder is in a combustion operation from various sensors such as a crank angle sensor, that is, the first cylinder is an explosive stroke. The ECU 10 controls the relay unit 13 during the combustion action of the cylinder 1, that is, during the explosion stroke of the piston 1 so that power is applied to the piezo material 10.

상기와 같이 본 발명의 1번 실린더에 의한 럼블링소음제거장치는 1번실린더의 연소작용시, 즉 1번 피스톤의 폭발행정시 크랭크축(1)의 선단부에 하향이 힘이 가해지기 때문에 크랭크축(1)이 진동을 하지 않게 되고 그에 따라 럼블링소음이 발생하지 않는 효과를 발휘한다.As described above, in the rubbing noise removing device according to the first cylinder of the present invention, since the downward force is applied to the distal end of the crankshaft 1 during the combustion action of the cylinder 1, that is, during the explosion stroke of the piston 1, the crankshaft (1) the vibration does not vibrate, thereby producing the effect of no rumbling noise.

본 발명은 기재된 구체예에 대해서만 상세히 설명되었지만 본 발명의 사상과 범주내에서 다양하게 변경 또는 수정할수 있음은 본 발명이 속하는 기술분야에서 통상의 지식을 가진자에게는 자명하다. 따라서 그러한 변경예나 수정예는 첨부한 본발명의 특허청구범위에 속한다 해야 할 것이다.Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made within the spirit and scope of the present invention. Therefore, such changes or modifications will have to belong to the appended claims.
