Abstract
본 발명은 서브프레임의 지지구조에 관한 것으로서, 차체에 서브프레임(60)을 지지하는 서브프레임(60)의 지지구조에 있어서, 서브프레임(60)의 후측 양단부에 차체와 결합할 수 있도록 형성된 보강공(65)과 차체에 서브프레임(60)의 후측 양단부의 보강공(65)과 결합될 수 있도록 형성된 결합공이 결합부재에 의해 결합되어 서브프레임(60)의 후측 양단부가 차체에 각각 더 지지되므로써, 서브프레임(60)의 강성이 높아져 비틀림 현상으로 인한 변형을 억제할 수 있을 뿐만 아니라, 정면 도는 경사 충돌시 서브프레임(60)의 밀림에 의한 부상으로부터 승객을 보호할 수 있는 안정성이 향상된다.The present invention relates to a support structure of a subframe, and in a support structure of a subframe 60 supporting a subframe 60 in a vehicle body, reinforcement formed to be coupled to the vehicle body at both rear ends of the subframe 60. The coupling holes formed to be coupled to the ball 65 and the vehicle body with the reinforcing holes 65 at both rear ends of the subframe 60 are coupled by the coupling member so that both rear ends of the subframe 60 are further supported by the vehicle body. In addition, the rigidity of the subframe 60 can be increased to suppress deformation due to the torsional phenomenon, and the stability to protect the passengers from injuries caused by the sliding of the subframe 60 during the frontal or inclined collision is improved.
Description
본 발명은 자동차의 서브프레임에 관한 것으로, 특히 서브프레임의 후측 양단부에 지지점을 각각 추가하여 상기 서브프레임의 강성을 증대할 수 있는 서브프레임의 지지구조에 관한 것이다.The present invention relates to a subframe of an automobile, and more particularly, to a support structure of a subframe that can increase the rigidity of the subframe by adding support points to both rear ends of the subframe.
일반적으로, 자동차의 서브프레임 구조는 제1도에 도시한 바와 같이 제1멤버(10)와, 제2멤버(20), 제3멤버(30) 및, 제4멤버(40)가 '井'형으로 결합되어 있고, '井'형 서브프레임(60)을 차체에 4점 지지로서 전측 2점(MT(Mounting)1, MT2)은 라디에이터 로우 멤버(미도시)에 지지되며, 후측 2점(MT3,MT4)은 대쉬 로우(미도시)에 지지된다.In general, as shown in FIG. 1, the subframe structure of the vehicle includes the first member 10, the second member 20, the third member 30, and the fourth member 40. Type, and the front two points MT (Mounting 1, MT2) are supported by a radiator row member (not shown) by supporting the '井' type subframe 60 on the vehicle body at four points. MT3 and MT4 are supported in dash rows (not shown).
이와 같은 4점 지지의 경우 외력에 대해서 서브프레임(60)이 충분한 강성을 가질 때 충돌, 진동, 강도, 내구성 등을 잘 만족할 수 있다Such four-point support can satisfactorily satisfy collision, vibration, strength, durability, etc. when the subframe 60 has sufficient rigidity against external force.
즉, 이상적인 서브프레임의 지지구조로서는 좌측 로워암(50) 및 우측 로워암(55)을 통해서 가장 큰 하중이 작용하는 위치인 제2멤버(20)와 좌측 로워암(50)의 결합부(A)와, 제3멤버(30)와 우측 로워암(55)의 결합부(A')을 연결하는 선과 거의 동일선상에 제4멤버(40)가 크로스되는 경우에는 전체 프레임에 변형이 거의 생기지 않는다.That is, as an ideal subframe support structure, the coupling portion A of the second member 20 and the left lower arm 50, which is the position where the largest load acts through the left lower arm 50 and the right lower arm 55, is applied. ) And when the fourth member 40 crosses substantially the same line as the line connecting the coupling portion A 'between the third member 30 and the right lower arm 55, almost no deformation occurs in the entire frame. .
그러나, 대부분의 자동차에서는 엔진과 트랜스미션 등의 간섭으로 제1도에 도시한 바와 같이 제4멤버의 위치가 좌측 로워암의 결합부(A)와 우측 로워암의 결합부(A')의 선상에서 뒤쪽으로 많이 이동되므로써, 프레임을 4점 지지하는 경우 외력 작용시 제2도에서와 같이 (가)방향으로 변형이 될 뿐만 아니라 정면 또는 경사 충돌시 후측 지지의 두점(MT3,MT4)이 대쉬에 연결되어 충돌시 상기 프레임에 의해 대쉬보드가 밀려 들어감으로써, 승객에게 큰 부상을 입힐 수 있어 안전운행에 지장을 초래하는 문제점이 있었다.However, in most automobiles, due to interference between the engine and the transmission, as shown in FIG. 1, the fourth member is positioned on the line between the engaging portion A of the left lower arm and the engaging portion A 'of the right lower arm. Since the frame is moved to the rear side, when supporting 4 points of the frame, when external force is applied, it is not only deformed in (A) direction but also two points (MT3, MT4) of the rear support in frontal or inclined collision are connected to the dash. When the dashboard is pushed by the frame at the time of a collision, it may cause a great injury to the passengers, which causes a problem in safe operation.
따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 이루어진 것으로서, 서브프레임의 후측 양단부에 각각 지지점을 추가하여 서브프레임의 변형을 방지할 수 있는 서브프레임의 지지구조를 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a support structure of a subframe that can prevent deformation of the subframe by adding support points to both rear ends of the subframe, respectively.

The both ends of each of the four reinforcing holes formed in each of the both ends of the fourth member and the reinforcing hole is characterized in that the coupling hole formed in the vehicle body is supported by the coupling member so that the subframe is supported by the vehicle body.
