본 고안은 자동차의 엔진 마운팅 구조에 관한 것으로, 특히 엔진 작동시의 진동을 규제하여 그에 의한 차체의 떨림현상을 저감하도록 된 엔진 장착구에 관한 것이다.The present invention relates to an engine mounting structure of a motor vehicle, and more particularly, to an engine mounting hole configured to reduce vibrations of a vehicle body by restricting vibration during engine operation.
종래에는 제1도에 도시된 바와같이, 도면에 도시되지 않은 자동차 프레임에 볼트로 고정되는 엔진 마운팅 브라켓(1)에 아우터파이프(2)와 인너파이프(3)가 동심원적으로 배설된 구조의 엔진 장착구(4)가 용접 등에 의해 접합되어 잇으며, 상기 엔진 장착구(4)의 아우터파이프(2)와 인너파이프(3) 사이에는 러버재의 부시(5)가 삽입되어 있다.Conventionally, as shown in FIG. 1, an engine having a structure in which an outer pipe 2 and an inner pipe 3 are concentrically disposed on an engine mounting bracket 1 that is bolted to an automobile frame not shown in the drawing. The mounting hole 4 is joined by welding or the like, and a rubber material bush 5 is inserted between the outer pipe 2 and the inner pipe 3 of the engine mounting hole 4.
엔진 장착구(4)의 인너파이프(3)는 엔진 하부에 장착된 브라켓과 결합된다. 상기 결합구조는 엔진 마운팅에서 널리 알려져 있는 것으로 본 명세서에서는 설명의 간략화를 위해 생략한다.The inner pipe 3 of the engine mounting hole 4 is coupled to the bracket mounted on the engine lower part. The coupling structure is well known in engine mounting, and is omitted herein for the sake of simplicity.
상기 엔진 장착구(4)는 엔진 중량에 의한 수직하중을 지지해야 할 뿐만 아니라, 안락한 승차감을 위해 엔진 작동시의 진종이 가능한 한 차체에 전달되지 않도록 진동 감쇠 또는 억제 기능을 수행해야 하며 주행시 차체로부터의 충격이 엔진으로 전달되는 것 또한 최대한 규제되어야 한다.In addition to supporting the vertical load by the engine weight, the engine mounting opening 4 must perform a vibration damping or suppressing function so that the final movement of the engine can be transmitted to the vehicle body as much as possible in order to provide a comfortable ride. The transmission of shocks to the engine should also be regulated as much as possible.
이를 위하여 아우터파이프(2)와 인너파이프(3)사이에 방진 및 완충재로서 러버재의 부시(5)가 제공되고, 상기 부시(5)내에는 엔진의 진동감쇠 또는 억제효과를 발휘하기 위해 인너파이프(3)의 상하로 이격된 위치에 빈 공간부(6)가 형성되어 있다.For this purpose, a bush 5 of a rubber material is provided between the outer pipe 2 and the inner pipe 3 as a dustproof and shock absorbing material, and the bush 5 has an inner pipe (in order to exert an vibration damping or suppression effect of the engine). The empty space part 6 is formed in the position spaced up and down of 3).
그러나, 이러한 부시(5) 구조에 있어서도 주행시 불규칙한 노면에 의한 충격 또는 엔진의 진동에 의해 빈 공간부(6)의 상면(a)과 하면(b)이 접촉되는 상태가 발생되며, 이 겨우에는 엔진 진동이 차체에 바로 전달되게 되어 차체의 과도한 떨림 및 소음이 발생되어 승차감을 저해하는 문제가 있었다.However, even in the structure of the bush 5, a state in which the upper surface a and the lower surface b of the empty space part 6 come into contact with each other due to an impact caused by an irregular road surface or vibration of the engine during driving, in which case the engine Vibration is immediately transmitted to the vehicle body, causing excessive tremor and noise of the vehicle body, thereby preventing the riding comfort.
본 고안의 목적은 종래의 엔진 장착구에 따른 문제점을 해소하기 위하여 엔진의 진동을 감쇠시키는 스프링 특성을 갖도록 개선된 구조의 엔진 장착구를 제공하는 것이다.It is an object of the present invention to provide an engine fitting of an improved structure to have a spring characteristic of damping the vibration of the engine in order to solve the problems caused by the conventional engine mounting.
본 고안에 따른 엔진 장착구는 자동차 프레임에 고정되는 브라켓에 접합된 아우터파이프와 그 속에 동심원적으로 배설되고 엔진과 연결되는 인너파이프, 상기 인너파이프와 아우터파이프 사이에 제공된 러버재의 부시를 포함하며, 상기 부시에는 인너파이프의 상하측에 중공의 공간부가 각각 형성되어 있고, 부시내에 형성된 공간부측으로 돌출되게 형성된 돌출부를 구비한 인너파이프 홀더가 제공되어 인너파이프와 함께 엔진의 진동을 감쇠하는 스프링 특성을 갖도록 구성되어 있다.An engine mounting device according to the present invention includes an outer pipe joined to a bracket fixed to an automobile frame, an inner pipe concentrically disposed therein and connected to an engine, and a bush of a rubber material provided between the inner pipe and the outer pipe. The bush is provided with hollow spaces on the upper and lower sides of the inner pipe, and has an inner pipe holder having a protrusion formed to protrude toward the space formed in the bush so as to have a spring characteristic to damp the vibration of the engine together with the inner pipe. Consists of.
이하, 본 고안의 일실시예를 도시한 첨부도면을 참고하여 본 고안을 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing an embodiment of the present invention.
제3도는 본 고안에 따라 엔진 장착구의 인너파이프(3)에 홀더(10)가 제공된 구조를 개략적으로 도시하고 있다.3 schematically shows a structure in which the holder 10 is provided in the inner pipe 3 of the engine mounting device according to the present invention.
상기 홀더(10)는 인너파이프(3)보다 직경이 큰 파이프를 인너파이프(3) 외측에 끼운 다음 여유부분을 접어 제4도와 같이 일체화 하고, 남은 부분은 돌출부(11)로 형성한다.The holder 10 inserts a pipe having a diameter larger than that of the inner pipe 3 to the outside of the inner pipe 3, and then folds the spare portion to integrate the same as in FIG. 4, and the remaining portion is formed as the protrusion 11.
상기 인너파이프(3)와 일체로된 홀더(10)를 제1도에 도시된 엔진장착구의 인너파이프(3) 위치에 배설하며, 이때 홀더(10)의 돌출부(11)가 인너파이프(3)와 아우터파이프(2) 사이에 제공된 부시(5) 내부 상하 위치에 각각 형성된 빈 공간부(a,b)들중 어느 하나를 행하도록 한다.The holder 10 integrated with the inner pipe 3 is disposed at the position of the inner pipe 3 of the engine mounting hole shown in FIG. 1, wherein the protrusion 11 of the holder 10 is the inner pipe 3. Any one of the empty space portions (a, b) formed at the upper and lower positions inside the bush (5) provided between the outer pipe and the outer pipe (2).
이와같이 인너파이프(3) 외측에 돌출부(11)가 형성된 홀더(10)를 형성함으로써 인너파이프가 엔진 작동시의 엔진 진동의 차체로 전달되는 것을 최대한 감소시킬 수 있다.As such, by forming the holder 10 having the protrusion 11 formed outside the inner pipe 3, it is possible to reduce as much as possible that the inner pipe is transmitted to the vehicle body of engine vibration during engine operation.
또한, 홀더(10)의 돌출부(11)를 부시(5)의 빈 공간부들(a,b)중 하나로 향하게 하여 공간부(a,b) 각각의 상하면의 접촉위치를 변경시켜 엔진 진폭을 제한하여 엔진 진동 및 주행중의 노면상태에 따른 충격의 영향을 최소화 하여 엔진의 보호 및 승차감 향상의 효과가 있다.In addition, the projection 11 of the holder 10 is directed to one of the empty spaces a and b of the bush 5 so as to change the contact position of the upper and lower surfaces of each of the spaces a and b to limit the engine amplitude. By minimizing the impact of the engine vibration and the impact of the road surface condition while driving, it is effective to protect the engine and improve the riding comfort.
