본 발명은 자동차의 서브프레임에 관한 것으로서, 더욱더 상세하게는 차량을 고속으로 운행중 정면 및 편심되게 충돌 사고등이 발생하는 경우에도 좌굴현상에 의해 충격에너지가 효과적으로 흡수되도록 하는 자동차의 서브프레임에 관한 것이다.The present invention relates to a subframe of a vehicle, and more particularly, to a subframe of a vehicle such that impact energy is effectively absorbed by a buckling phenomenon even when a collision accident or the like occurs in front and eccentricity while the vehicle is running at high speed. .

일반적으로 자동차의 서브프레임 서스펜션멤버라고도 불리며, 서스펜션이나 파워트레인(동력전달장치의 부품)을 조립하고 프레임이나 보디에 부착되는 자동차의 부분적인 골격을 이루는 부품이다.Generally referred to as a subframe suspension member of an automobile, it is a component that forms a partial skeleton of an automobile that is assembled with a suspension or power train (part of a power transmission device) and attached to a frame or a body.

대부분의 FF(FRONT ENGINE DRIVE)차량의 경우에는 도 1과 도 2에 도시하고 있는 바와 같이, 후방크로스멤버(120’)와 전방크로스멤버(110’) 및 좌측멤버(140’)와 우측멤버(130’)의 4개의 부재를 대략 사각형(또는 우물정자)의 형상으로 용접한 서브프레임(100’)구조를 채택하고 있다.In the case of most FF (FRONT ENGINE DRIVE) vehicles, as shown in FIGS. 1 and 2, the rear cross member 120 'and the front cross member 110', the left member 140 'and the right member ( A subframe 100 'structure in which four members of 130' are welded in a substantially rectangular (or well sperm) shape is adopted.

이러한 종래 서브프레임(100’)은 좌측멤버(140’)와 우측멤버(130’)의 선단부가 각각 용착되어 있는 전방크로스멤버(110’)는 차체의 전면부를 형성하는 프론트사이드멤버(200’)의 선단부에 결합되고, 상기 좌측멤버(140’)와 우측멤버(130’)는 후방크로스멤버(120’)에 의한 지지를 받으며 차체의 측면 중앙부를 형성하는 센터플로워 사이드멤버(300’)의 선단부에 결합되어, 차량을 운행중 정면 충돌사고 등이 발생하여 차량의 정면에서 충격하중이 발생하는 경우 서브프레 임(100’)의 자체 강성에 의해 충격에너지를 흡수하여 차실에 탑승한 승원이 부상당하는 것을 억제시키고 있다.Such a conventional subframe 100 'is a front cross member 110' on which front ends of the left member 140 'and the right member 130' are welded, respectively, forming a front part of the vehicle body. It is coupled to the front end of the left member 140 'and the right member 130' is supported by the rear cross member 120 'and the front end of the center follower side member 300' forming a central side of the vehicle body When the collision occurs while driving the vehicle, and the impact load occurs in front of the vehicle, the occupant in the cabin is absorbed by absorbing the impact energy by its own rigidity of the subframe 100 '. I suppress it.

그러나 이러한 종래 자동차의 서브프레임(100’)은 센터플로어 사이드멤버(300’)의 하단에 트랜스미션이 장착되도록 볼팅체결되어 있는 트랜스미션마운팅브라켓트(400’)와는 연결이 이루어지지 않게 됨으로써, 차량을 운행 중 중속 이상의 고속 상태에서 정면 충돌사고가 발생 하게되면 서브프레임(100’)이 자체 강성에 의해 충격에너지가 그대로 차실로 유입되어 차실에 탑승한 승원이 강한 충격을 받게됨은 물론, 편심되게 충돌시에는 모멘트에 의한 회전변형으로 대쉬 하단부 차체의 변형이 과다하게 이루어지게 되는 문제점이 있었다.However, the subframe 100 'of such a conventional vehicle is not connected to the transmission mounting bracket 400' which is bolted so that the transmission is mounted on the bottom of the center floor side member 300 '. If a frontal collision occurs at a high speed of medium speed or more, the subframe 100 'has its own stiffness so that the impact energy is directly introduced into the cabin, and the occupant in the cabin receives a strong shock. There was a problem that the deformation of the lower vehicle body of the dash excessively made by the rotational deformation by.

한편, 상기와 같이 대쉬 하단부의 차체 변형이 발생하게되면 스티어링컬럼등이 차실로 밀려들어가면서 차량을 운행하고 있는 운전자의 무릅등과 같은 신체에 접촉되면서 상해를 입히게 되는 문제점이 있었다.On the other hand, when the vehicle body deformation of the lower end of the dash occurs as described above, the steering column is pushed into the vehicle room, there is a problem that injuries while contacting the body, such as the knees of the driver running the vehicle.

본 발명의 목적은 차량을 운행중 고속 충돌시 좌측멤버와 우측멤버가 센터플로어판넬의 하단부에 설치되어 있는 트랜스미션마운팅브라켓트와 연결되도록 하는 지지패널에 의해 좌굴현상이 발생하면서 폭넓게 충돌에너지가 흡수되도록 함과 동시에 대쉬 하단부 차체 변형량을 최소화시켜 차실내부로 스티어링컬럼이 밀려들어가 운전자의 무릅등과 같은 신체와 접촉하는 것이 억제되도록 함으로써, 차량을 고속으로 운행시 정면 및 편심되게 충돌사고가 발생하는 경우에도 충격에너지가 효과 적으로 흡수되어 차실에 탑승한 승원이 부상당하지 않도록 하는 자동차의 서브프레임을 제공하는데 그 목적이 있다.An object of the present invention is to allow a collision panel to absorb a wide range of collision energy while the buckling phenomenon occurs by a support panel that allows the left and right members to be connected to the transmission mounting bracket installed at the lower end of the center floor panel during high-speed collision while driving the vehicle. At the same time, by minimizing the amount of deformation of the lower body of the dash, the steering column is pushed into the interior of the vehicle to prevent contact with the body, such as the driver's knees. The purpose is to provide a subframe of a vehicle that is effectively absorbed so that the occupants in the cabin are not injured.

By 120.

이 구성에 의하면, 차량을 운행중 정면충돌사고등이 발생하여 프론트사이드멤버(200)에 충격이 가해지게 되면 전방크로스멤버(110)가 충격에너지를 흡수하면서 좌측멤버(140) 및 우측멤버(130)로 충격에너지를 전달하게되고, 상기 전방크로스멤버(110)를 통해 전달된 충격에너지는 좌측멤버(140) 및 우측멤버(130)에서 재차 흡수 도이지게되며, 상기 좌측멤버(140) 및 우측멤버(130)에서 재차 흡수하고 남은 충격에너지는 좌측멤버(140) 및 우측멤버(130)의 후단부와 지지패널(120)의 선단부가 결합되어 있는 결합부위가 차량의 외측으로 좌굴되면서 충격에너지를 흡수하게되고, 상기 결합부위가 좌굴되면서 흡수하고남은 충격에너지는 최종적으로 트랜스미션마운팅브라켓트(400)에 후단부가 결합되어 있는 지지패널(120)을 통해 흡수 및 폭넓게 분산되어지게 된다.According to this configuration, when a front collision member is generated while driving a vehicle, when the impact is applied to the front side member 200, the front cross member 110 absorbs the impact energy and the left member 140 and the right member 130. Impact energy is transmitted to the, and the energy transmitted through the front cross member 110 is absorbed again in the left member 140 and the right member 130, the left member 140 and the right member ( The impact energy remaining after absorbing again at 130 is absorbed by the coupling part, which is coupled to the rear end of the left member 140 and the right member 130 and the front end of the support panel 120, to the outside of the vehicle to absorb the impact energy. The impact energy remaining after absorbing the coupling portion is finally absorbed and widely distributed through the support panel 120 having the rear end coupled to the transmission mounting bracket 400.

따라서, 차량을 고속으로 운행시 정면 및 편심되게 충돌사고가 발생하는 경우에도, 좌굴현상에 의해 충격에너지가 효과적으로 흡수되어지게 됨으로써, 대쉬 하단부의 변형이 최소화되어 차실내부로 스티어링컬럼이 밀려들어가 운전자의 무릅등과 같은 신체와 접촉하는 것을 억제시키게 되는 것이다.Therefore, even when a crash accident occurs in front and eccentricity when driving the vehicle at high speed, the impact energy is effectively absorbed by the buckling phenomenon, so that deformation of the lower end of the dash is minimized and the steering column is pushed into the vehicle interior. It is to suppress contact with the body such as knees.
