도 3 내지 도 5를 참조하면, 본 발명 실시예는 프론트멤버(1)와, 상기 프론트멤버(1)의 양단에 차량의 전후 방향으로 길게 결합되는 사이드멤버(3)들만으로 이루어진 서브프레임(5)과; 상기 서브프레임(5)의 프론트멤버(1)에 평행하게 상기 두 사이드멤버(3)에 연결되어, 상기 사이드멤버(3) 및 프론트멤버(1)와 함께 내부에 사각형의 폐단면을 이루는 스티어링하우징(7)을 포함하여 구성된 구조이다.3 to 5, the exemplary embodiment of the present invention includes a front frame 1 and a subframe 5 composed of only side members 3 coupled to both ends of the front member 1 in a longitudinal direction of the vehicle. and; A steering housing connected to the two side members 3 in parallel with the front member 1 of the subframe 5 to form a rectangular closed section inside the side member 3 and the front member 1. It is a structure including (7).

즉, 종래의 서브프레임(5)을 구성하던 리어멤버를 제거하고, 상기 리어멤버가 담당하던 역할을 상기 스티어링하우징(7)이 병행하여 수행할 수 있도록 함으로 써, 상기 리어멤버가 불필요하게 되어 부품수 저감의 효과 및 중량저감의 효과를 얻을 수 있도록 한 것이다.That is, by removing the rear member constituting the conventional subframe 5 and allowing the steering housing 7 to perform the role played by the rear member in parallel, the rear member becomes unnecessary. The effect of water reduction and weight reduction can be obtained.

상기 서브프레임(5)의 사이드멤버(3)에는 제2마운팅브라켓(9)이 결합되고, 상기 제2마운팅브라켓(9)의 상측에 상기 스티어링하우징(7)이 위치하며, 상기 스티어링하우징(7)의 상측을 감싸서 상기 제2마운팅브라켓(9)과 결합되어 상기 스티어링하우징(7)을 고정하는 제1마운팅브라켓(11)이 구비된 구조이다.The second mounting bracket 9 is coupled to the side member 3 of the subframe 5, the steering housing 7 is positioned above the second mounting bracket 9, and the steering housing 7 The first mounting bracket 11 is coupled to the second mounting bracket 9 so as to surround the upper side thereof to fix the steering housing 7.

상기 스티어링하우징(7)의 외측에는 고무부쉬(13)가 결합되고, 상기 제2마운팅브라켓(9)과 제1마운팅브라켓(11)은 상기 고무부쉬(13)의 외측을 고정함으로써 상기 스티어링하우징(7)을 고정하도록 된 구조이다.A rubber bush 13 is coupled to the outer side of the steering housing 7, and the second mounting bracket 9 and the first mounting bracket 11 fix the outer side of the rubber bush 13 to fix the steering housing ( 7) It is structure to fix.

따라서, 상기 사이드멤버(3)와 상기 스티어링하우징(7) 사이에서는 상기 고무부쉬(13)에 의해 진동이 절연되어, 상기 서브프레임(5) 측으로부터 상기 스티어링하우징(7)을 타고 운전자에게 진동이 전달되는 것을 차단할 수 있게 된다.Accordingly, the vibration is insulated between the side member 3 and the steering housing 7 by the rubber bush 13, so that the driver may receive the vibration from the subframe 5 side by the steering housing 7. You can block delivery.

상기 제2마운팅브라켓(9)은 ㄷ 자형 단면구조를 가지고 상기 사이드멤버(3)의 내측에 결합된 구조로 하였는 바, 상기 제2마운팅브라켓(9)은 사이드멤버(3)와 함께 폐단면을 형성하는 상태가 되어 강한 지지력을 제공할 수 있게 된다.The second mounting bracket 9 has a c-shaped cross-sectional structure and has a structure coupled to the inner side of the side member 3. The second mounting bracket 9 has a closed end surface with the side member 3. It becomes the state to form and can provide strong support force.

또한, 상기 제2마운팅브라켓(9)에는 양쪽에 볼트구멍을 구비하여, 상기 제1마운팅브라켓(11)과 결합될 수 있도록 하였으며, 이에 상응하는 상기 제1마운팅브라켓(11)은 상기 스티어링하우징(7)을 감싸도록 중앙부가 환형으로 형성되고 양단에 상기 제2마운팅브라켓(9)과 결합되기 위한 볼트구멍이 구비된 플랜지가 형성된 구조이다.In addition, the second mounting bracket 9 has bolt holes at both sides thereof, so that the second mounting bracket 9 can be combined with the first mounting bracket 11, and the first mounting bracket 11 corresponding thereto is the steering housing ( 7) The center part is formed in an annular shape so as to surround the flange having a bolt hole for coupling with the second mounting bracket 9 at both ends.

상기한 바와 같이 구성된 차량의 서브프레임(5)과 스티어링장치 장착구조는 종래의 서브프레임(5)에 스티어링하우징(7)이 장착된 구조에 비하여, 서브프레임(5)을 이루던 리어멤버가 제거되어 소요 부품수가 저감되고 중량이 저감되어 차량의 제작원가를 절감시키는 효과와 연비가 개선되는 효과를 가져오게 된다.The subframe 5 and the steering device mounting structure of the vehicle configured as described above are removed from the rear member forming the subframe 5 as compared to the structure in which the steering housing 7 is mounted on the conventional subframe 5. The required number of parts is reduced and the weight is reduced, resulting in the effect of reducing the production cost and fuel economy of the vehicle.

또한, 상기 서브프레임(5)에서 상기 제2마운팅브라켓(9)을 장착하는 위치를 엔진마운팅브라켓이 위치하는 곳에 인접하게 설정하면, 상기 제2마운팅브라켓(9)이 상기 서브프레임(5)과 형성하는 폐단면 구조에 의해 강한 강성이 확보되어 차량의 진동 소음에 유리하게 작용하게 되는 효과를 얻을 수 있다.In addition, when the position where the second mounting bracket 9 is mounted in the subframe 5 is set adjacent to the position where the engine mounting bracket is located, the second mounting bracket 9 may be connected to the subframe 5. By forming the closed cross-sectional structure to form a strong stiffness can be obtained to advantageously act on the vibration noise of the vehicle.
