Description
본 발명은 차량의 배기가스 촉매컨버터에 관한 것으로, 특히 촉매컨버터를 변속기 하우징에 스테이와 부시를 매개로 연결하여 촉매컨버터를 안정되게 지지하면서 차량의 소음을 저감시키도록 배기가스 촉매컨버터 지지장치에 관한 것이다.BACKGROUND OF THE
종래 차량의 디젤엔진은 뛰어난 연비, 출력 등에도 불구하고, 그 특성상 공기 과잉률이 큰 상태에서 연소가 이루어지기 때문에 배기가스 중에는 가솔린 엔진과 달리 일산화탄소와 탄화수소의 배출량이 적은 반면에 질소산화물과 그을음과 같은 입자성 물질이 상당히 배출되는 단점을 갖고 있다.Despite the excellent fuel efficiency and output, diesel engines of conventional vehicles are burned in a state where the excess air ratio is large, and therefore, unlike gasoline engines, the exhaust gas has a low emission of carbon monoxide and hydrocarbons, whereas nitrogen oxides and soot It has the disadvantage that the same particulate matter is significantly released.
상기와 같은 디젤엔진의 배기가스 유해성분을 저감시키기 위해 WCC(Warm up Catalytic Converter) 후처리 장치가 차량에 적용되고 있는 바, 이 WCC 후처리장치는 원통형상을 한 케이스의 양측에 입구와 출구를 서로 대향되게 형성시키고, 상기 케이스의 내부에 배기가스 중에 포함된 여러 가지 유해 성분을 산화시키는 담체가 장착되며, 상기 담체와 케이스 사이에는 매트가 개재되는 구조로 이루어진다.In order to reduce the exhaust gas harmful components of the diesel engine, a WCC (Warm up Catalytic Converter) post-treatment device is applied to a vehicle. The WCC post-treatment device has an inlet and an outlet on both sides of a cylindrical case. The carrier is formed to face each other, and a carrier for oxidizing various harmful components contained in the exhaust gas is installed inside the case, and a mat is disposed between the carrier and the case.
한편 엔진과 변속기가 종축으로 배치되어 있는 후륜구동 대형 차량의 경우에 파워트레인 모드와 좌우 양측의 배기계 모드에 의해 차량의 가속시에 투과음과 부밍소음이 매우 커지는 경향이 있고, 이를 저감하기 위해 WCC 후처리장치에 스테이를 설치하여 WCC의 장착장성을 보강하고 있지만, 상기 스테이 그 자체는 강성이 있어서 진동이나 충격을 적절히 흡수해서 완충시키는 기능이 미흡하고, 배기계와 파워트레인계를 잡아주는 강성이 양쪽으로 나누어지기 때문에 가속 투과음 및 부밍을 저감시키는 데에 한계가 있었다.On the other hand, in the case of a rear wheel drive large vehicle in which the engine and the transmission are arranged in the longitudinal axis, the transmission sound and the booming noise tend to be very large when the vehicle is accelerated by the powertrain mode and the exhaust system modes on both the left and right sides, and to reduce the WCC The stay is installed in the aftertreatment device to reinforce the mounting stiffness of the WCC. However, the stay itself is rigid, so that the function of absorbing vibrations and shocks is not adequately absorbed and buffered. Since it is divided into, there is a limit in reducing the acceleration transmission sound and the booming.
이에 본 발명은 상기한 사정을 감안하여 안출된 것으로, 좌우 양측의 WCC 후처리장치를 스테이와 부시를 매개로 변속기의 하부와 연결하여 WCC 후처리장치 및 변속기의 지지강성을 증대시키고, 상기 부시를 매개로 배기계와 변속기의 진동을 적절히 흡수해서 저감시켜 차량의 가속 소음과 부밍소음을 현저하게 줄여서 차량의 승차감을 향상시키도록 한 배기가스 촉매컨버터의 지지장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above circumstances, by connecting the WCC post-treatment devices on both the left and right sides with the lower part of the transmission via the stay and the bush to increase the support rigidity of the WCC post-treatment device and the transmission, It is an object of the present invention to provide a support device for an exhaust gas catalytic converter in which the vibration of the exhaust system and the transmission is appropriately absorbed and reduced to significantly reduce the acceleration noise and the booming noise of the vehicle to improve the ride comfort of the vehicle.
상기와 같은 목적을 달성하기 위한 본 발명은, 좌우 양측의 촉매컨버터와 중앙의 변속기 하우징이 차량의 폭방향을 따라 연장되어 형성된 하나의 스테이를 매개로 서로 일체로 연결된다.The present invention for achieving the above object, the catalytic converter on the left and right sides and the transmission housing in the center is integrally connected to each other via one stay formed by extending along the width direction of the vehicle.
상기 스테이의 좌우 양단이 상기 촉매컨버터에 각각 체결되어 연결되고, 상기 스테이의 길이방향을 따라 2군데가 상기 변속기 하우징에 부시를 개재하여 체결 된다. The left and right ends of the stay are fastened and connected to the catalytic converter, respectively, and two places are coupled to the transmission housing through a bush in the longitudinal direction of the stay.
본 발명에 따른 배비가스 촉매컨버터의 지지장치에 의하면, 좌우 양측의 WCC 후처리장치에 차량의 폭방향을 따라 연장되어 형성된 1개의 스테이의 양단이 각각 체결되어 일체로 연결됨과 더불어 상기 스테이의 길이방향을 따른 소정 부위의 2군데가 부시를 매개로 변속기 하우징의 하부와 체결되어, 상기 한 몸체로 이루어진 스테이를 매개로 좌우 양측의 WCC 후처리장치와 변속기가 일체로 연결됨에 따라 WCC 후처리장치와 변속기의 지지강성이 증대되어 진동 및 충격을 저감시킬 수 있고, 상기 부시에 의해 배기계 및 변속기의 진동 및 충격이 적절히 흡수되어 완화됨으로써 배기계 및 변속기의 진동 및 충격이 효과적으로 저감되어 차량의 가속시의 소음과 부밍소음이 현저하게 줄어들어 차량의 승차감을 향상시키는 등의 효과가 있다. According to the support device of the exhaust gas catalytic converter according to the present invention, both ends of one stay formed extending along the width direction of the vehicle to the WCC post-treatment devices on both the left and right sides are fastened and connected integrally, respectively, and in the longitudinal direction of the stay. WCC post-processing device and the transmission is connected to the lower portion of the transmission housing via a bush through two places of the predetermined part along the body, and the WCC post-processing device and the transmission on both sides of the left and right sides are integrally connected to each other through the stay consisting of one body. The vibration and shock of the exhaust system and transmission are properly absorbed and mitigated by the bush, and the vibration and shock of the exhaust system and the transmission are effectively reduced to reduce the vibration and shock of the vehicle. The booming noise is significantly reduced, thereby improving the riding comfort of the vehicle.
