엔진지지용 롤로드의 구조Structure of Roll Rod for Engine Support

본 고안은 자동차의 엔진을 지지하는 엔진지지용 롤로드에 관한 것으로, 특히 엔진과 차체 사이를 연결시켜 엔진의 롤진동을 흡수하도록 된 롤로드가 고무를 매개로 가류접착되어 엔진의 피치방향의 진동에도 효과적으로 차체를 절연할 수 있도록 된 엔진지지용 롤로드의 구조에 관한 것이다.The present invention relates to an engine support roll rod for supporting an engine of an automobile, and in particular, a roll rod, which is connected between the engine and the vehicle body to absorb roll vibration of the engine, is vulcanized and adhered via rubber to vibrate in the pitch direction of the engine. The present invention relates to a structure of a roll rod for supporting an engine that can effectively insulate a vehicle body.

일반적으로 자동차의 엔진은 내부의 피스톤과 컨넥팅로드의 상하운동에 의한 중심위치의 주기적인 변화와, 실린더 축방향으로 생기는 왕복운동부분에서 발생되는 관성력, 커넥팅로드가 크랭크축의 좌우로 흔들림에 따라 발생되는 관성력 및, 크랭크축에 가해지는 회전력의 주기적인 변화에 따른 것등에 의해 동작중 진동과 소음을 유발시키는 것이 통상적이다.In general, the engine of a vehicle is generated by the periodic change of the center position due to the vertical movement of the piston and the connecting rod, the inertia force generated in the reciprocating part in the cylinder axial direction, and the connecting rod swinging from the left and right of the crankshaft. It is common to cause vibration and noise during operation due to the inertia force and the periodic change of the rotation force applied to the crankshaft.

이에 따라 엔진은, 동작중 차체로 전달되는 진동을 최소화하거나, 엔진의 움직임을 제어하여 내구성을 향상시키기 위해 엔진룸내에 장착시 엔진의 하부에 다수개(통상 3내지 4곳)의 지점으로 적절한 스프링강성을 지닌 고무로 제작된 엔진마운트를 매개로 서브프레임상에 장착되고 있다.Accordingly, the engine has a number of springs (usually three or four) at the bottom of the engine when mounted in the engine room to minimize vibrations transmitted to the vehicle body during operation or to improve durability by controlling the movement of the engine. It is mounted on a subframe via an engine mount made of rigid rubber.

또한, 상기 엔진의 상측과 스트럿하우징 사이에는 롤로드가 설치되어 있어 엔진의 차체전후방향으로의 진동을 제어하도록 되어 있는 바, 이 롤로드는 마운팅부시를 매개로 차체에 장착되어 지지되게 되어 있다.Further, a roll rod is provided between the upper side of the engine and the strut housing so as to control the vibration of the engine in the front and rear directions of the engine, and the roll rod is mounted on the vehicle body via a mounting bush to be supported.

도 1은 상기한 종래의 엔진지지용 롤로드가 장착된 상태를 나타내는 개략적인 측면도인 바, 즉 엔진(101)의 상측과 차체의 스트럿하우징(102) 사이에 차체의 길이방향으로 롤로드(103)가 장착되어 있는 바, 이 롤로드(103)는 로드(104)의 양선단부위에 각기 접합된 마운팅부시(105)를 갖추고서 엔진(101)측에 돌출되게 접합된 브래킷(106)과 스트럿하우징(102)측에 돌출되게 접합된 브래킷(107)에 나사체결되어 고정되어 있다.1 is a schematic side view showing a state in which the conventional engine supporting roll rod is mounted, that is, the roll rod 103 in the longitudinal direction of the vehicle body between the upper side of the engine 101 and the strut housing 102 of the vehicle body. The rod rod 103 is equipped with mounting bushes 105 joined to both ends of the rod 104, and the bracket 106 and the strut housing joined to protrude to the engine 101 side. It is screwed and fixed to the bracket 107 joined so that it may protrude on the (102) side.

여기서 상기 롤로드(103)의 양선단부위에 구비된 마운팅부시(105)는 각각 외측파이프(108)와 내측파이프(109)의 사이에 고무부시(110)가 개재되어 가류접착된 구조로 되어 있다.Here, the mounting bushes 105 provided at both ends of the roll rod 103 have a structure in which a rubber bush 110 is interposed between the outer pipe 108 and the inner pipe 109 to be vulcanized.

따라서 상기 엔진(101)측에 돌출되게 접합된 브래킷(106)과 스트럿하우징(102)측에 돌출되게 접합된 브래킷(107) 사이에 장착된 롤로드(103)는 엔진(101)의 전후방향의 진동인 롤진동을 효과적으로 감쇠시켜 진동을 절연하도록 되어 있다.Therefore, the roll rod 103 mounted between the bracket 106 protrudingly bonded to the engine 101 side and the bracket 107 protrudingly bonded to the strut housing 102 side has a front and rear direction of the engine 101. The roll vibration, which is vibration, is effectively attenuated to insulate the vibration.

그런데 상기와 같이 엔진(101)의 상측과 스트럿하우징(102) 사이를 따라 차체의 길이방향으로 설치되는 롤로드(103)는, 상기 엔진(101)의 좌우방향인 피치방향의 진동에는 효과적으로 대응할 수 없는 구조로 되어 있어, 이로 인해 차체는 엔진(101)의 피치방향의 진동에 좌우방향으로 떨리게 되는 진동을 유발시키게 되는 단점이 있었다.However, the roll rod 103 installed in the longitudinal direction of the vehicle body along the upper side of the engine 101 and the strut housing 102 as described above can effectively cope with the vibration in the pitch direction in the left and right directions of the engine 101. It has a structure that does not have, because of this, the vehicle body has a disadvantage that causes the vibration to be shaken in the left and right directions in the pitch direction of the engine 101.

이에 본 고안은 상기와 같은 단점을 해소하기 위해 안출된 것으로, 엔진의 상측과 차체 사이를 고정시켜 엔진의 전후방향의 롤진동을 절연하는 롤로드가 고무를 매개로 접합되어 있어 엔진의 피치방향의 진동에도 절연효과를 나타낼 수 있게 됨으로써, 차체로 전달되는 진동을 효과적으로 절연시킬 수 있도록 된 엔진지지용 롤로드의 구조를 제공함에 그 목적이 있다.The present invention has been devised to solve the above disadvantages, the roll rod is fixed between the upper side of the engine and the vehicle body to insulate the roll vibration in the front and rear direction of the engine is connected via rubber to the pitch direction of the engine The purpose of the present invention is to provide a structure of an engine support roll rod that can effectively insulate the vibration transmitted to the vehicle body by being able to exhibit an insulation effect even in vibration.
