Description
본 발명은 자동차 엔진의 오일팬과 변속기의 결합부 흡음장치에 관한 것으로서, 더 상세하게는 엔진실린더블록 하부의 오일팬과 변속기의 결합부 사이에 소음 및 진동을 흡수 및 차단하는 흡음재를 개재시켜 엔진과 변속기에서 발생되는 진동 및 소음을 효과적으로 흡수 및 차단시키기 위한 자동차 엔진의 오일팬과 변속기의 결합부 흡음장치에 관한 것이다.The present invention relates to a sound absorbing device of a coupling part of an oil fan and a transmission of an automobile engine. The present invention relates to a sound absorbing device of a coupling part of an oil fan and a transmission of an automobile engine for effectively absorbing and blocking vibration and noise generated from a transmission and a transmission.
일반적으로 자동차의 엔진이 발생하는 토크는 회전속도의 변화에 관계없이 거의 일정하며 출력은 회전속도에 따라 크게 변화하는 특성을 가지고 있다.In general, the torque generated by the engine of a car is almost constant regardless of the change of rotational speed, and the output varies greatly according to the rotational speed.
그러나 자동차가 주행하는 경우에 필요로 하는 구동력은 화물을 실은 경우 또는 도로상황 및 주행속도 등에 의해 크게 변화시키는 장치 즉, 클러치와 추진축 사이에 설치되어 자동차의 주행상태 변화에 따른 엔진의 회전력을 증대시키거나 감소시키는 장치가 필요하게 되는데, 이와같은 역할을 하는 장치를 변속기(Transmission)라고 하며 엔진을 조정할때나 엔진을 워밍업시킬때 엔진과 구동륜과의 연결을 일정시간동안 단속하는 역할도 하게 된다.However, the driving force required when the vehicle is driven is installed between the load or the road conditions and the driving speed, that is, between the clutch and the propulsion shaft, so as to increase the rotational force of the engine according to the change of the driving state of the vehicle. A device that does this is called a transmission, which also controls the connection between the engine and the drive wheels for a period of time when adjusting the engine or warming up the engine.
이러한 변속기는 엔진에 연결되게 결합되며 특히 하부면은 엔진하부의 오일팬과 결합되게 된다.Such a transmission is coupled to be connected to the engine, in particular the lower surface is to be coupled to the oil pan under the engine.
한편 오일팬(Oil Pan)은 엔진실런더블록의 가장 아래에 있는 엔진오일의 받침대를 말한다.On the other hand, the oil pan (Oil Pan) refers to the base of the engine oil at the bottom of the engine cylinder block.
이러한 자동차 엔진의 오일팬과 변속기의 결합부는 도 2에 도시된 바와같이 엔진실린더블록(1)과 이의 하부 오일팬(2) 일측면으로 변속기(10)가 밀착결합되게 된다.The coupling part of the oil fan and the transmission of the automobile engine is in close contact with the transmission 10 to one side of the engine cylinder block 1 and its lower oil fan 2 as shown in FIG.
이와같은 종래 엔진의 오일팬과 변속기의 결합부는 흡음재나 기타 진동 흡수수단 등이 전혀없이 오일팬과 변속기가 직접 결합되어 엔진과 변속기에서 발생하는 소음 및 진동 등에 의해 결합부위에서 진동에 의한 소음이 심하게 발생하게 되는데, 이러한 소음은 차량의 고속주행시 특히 심하게 발생하게 되며 차량의 NVH(Noise Vibration Harshness) 성능이 저하되는 등의 문제점이 있다.The coupling part of the oil pan and the transmission of the conventional engine is directly coupled to the oil pan and the transmission without any sound absorbing material or other vibration absorbing means, and the noise caused by the vibration at the coupling part is severely affected by the noise and vibration generated from the engine and the transmission. This noise is generated particularly badly during high-speed driving of the vehicle, and there is a problem such as deterioration of the noise vibration performance (NVH) of the vehicle.
따라서 본 발명의 목적은 상기와 같은 문제점을 해결하기 위하여 엔진실린더블록 하부에 설치된 오일팬과 변속기의 결합부위에 소음 및 진동을 흡수 및 차단하는 흡음재를 개재시켜 엔진과변속기의 소음, 진동을 효과적으로 흡수 및 차단하여 차량의 NVH 성능을 향상시키기 위한 자동차 엔진의 오일팬과 변속기의 결합부 흡음장치를 제공하는데 있다.Accordingly, an object of the present invention is to effectively absorb the noise and vibration of the engine and the transmission by interposing a sound absorbing material for absorbing and blocking the noise and vibration in the coupling portion of the oil fan and the transmission installed in the lower portion of the engine cylinder block to solve the above problems. And it provides a sound absorbing device of the coupling portion of the oil fan and the transmission of the automobile engine to improve the NVH performance of the vehicle by blocking.
상기와 같은 목적을 달성하기 위한 본 발명의 수단은 실린더블록(1)과 이의 하부에 설치된 오일팬(2)의 일측면으로 밀착 결합되는 변속기(10)에 있어서,Means of the present invention for achieving the above object in the transmission 10 is tightly coupled to one side of the cylinder block (1) and the oil pan (2) installed below it,
상기 오일팬(2)과 변속기(10)의 결합부 사이에 소음 및 진동흡수용 흡음재(20)를 개재시키는 것이 특징이다.The sound absorbing material 20 for absorbing noise and vibration is interposed between the coupling part of the oil pan 2 and the transmission 10.
