Description
본 발명은 차량용 리어크로스멤버 설치구조에 관한 것으로서, 특히 차량의 후방에 구비된 리어플로어를 지지고정하는 크로스멤버를 리어프레임에 형성된 고정부로 삽입시켜 바닥면에 고정시킴에 따라 차체의 강성을 높일 수 있게 한 차량용 리어크로스멤버 설치구조에 관한 것이다.The present invention relates to a vehicle rear cross member installation structure, and in particular, by inserting a cross member supporting a rear floor provided at the rear of the vehicle into a fixing part formed in the rear frame and fixing it to the floor surface, the rigidity of the vehicle body can be increased. A rear cross member mounting structure for a vehicle is provided.
일반적으로 차량의 크로스멤버는 차량의 진행방향에 대해 직각방향으로 차체의 골격이 이루어지게 하여 강도나 강성을 높이도록 한 것이다.In general, the cross-member of the vehicle is to make the skeleton of the vehicle body in a direction perpendicular to the traveling direction of the vehicle to increase the strength or rigidity.
이러한 크로스멤버는 차체의 전후 및 좌우측의 비틀림이나 변형을 방지하며, 본 발명은 차체의 후방측에 구비된 리어플로어를 지지보강시켜 주는 리어크로스멤버에 관한 것이다.The cross member prevents twisting and deformation of the front, rear, left, and right sides of the vehicle body, and the present invention relates to a rear cross member for supporting and strengthening the rear floor provided on the rear side of the vehicle body.
이와같은 종래의 구조를 설명하면 도 5에서 보는 바와같이 전후방향으로 구비된 리어프레임(3)의 상부 플랜지(4)가 리어플로어(6)의 하부면에 접촉되어 용접고정되고, 리어프레임(3)의 하부면에는 크로스멤버(1)를 용접고정하였다.Referring to the conventional structure, as shown in FIG. 5, the upper flange 4 of the rear frame 3 provided in the front-rear direction is welded and fixed by contacting the lower surface of the rear floor 6 and the rear frame 3. On the lower surface of the cross member (1) was fixed to the welding.
이러한 크로스멤버(1)는 리어프레임(3)과 함께 리어플로어(6)에 고정되어 리어플로어(6)를 지지하므로서 강성을 부여하고 있으나, 크로스멤버(1)가 리어프레임(3)의 하부면에 용접고정됨에 따라 고정견고성이 취약하였다.The cross member 1 is fixed to the rear floor 6 together with the rear frame 3 to provide rigidity by supporting the rear floor 6, but the cross member 1 is provided on the lower surface of the rear frame 3. The fixed rigidity was weak as the welding was fixed.
따라서, 차량의 충돌시 용접고정된 부위가 파손 및 손상되어 차체의 안정성을 보장할 수 없었고, 리어플로어(6) 하부에 설치된 리어프레임(3)의 하부 소정위치에 고정설치되는 크로스멤버(1)의 설치위치가 부정확하여 조립작업공차가 심하여 제품의 품질과 신뢰도를 저하시키는 문제점이 있었다.Therefore, the welded part is damaged and damaged during the collision of the vehicle, and thus the stability of the vehicle body cannot be guaranteed, and the cross member 1 fixedly installed at the lower predetermined position of the rear frame 3 installed under the rear floor 6 is fixed. There was a problem that the installation position of the inaccurate and the assembly work tolerance is severe, which degrades the quality and reliability of the product.
본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 안출한 것으로서, 차량의 후방에 구비된 리어플로어를 지지고정하는 크로스멤버를 리어프레임에 형성된 고정부로 삽입시켜 리어프레임의 바닥면에 고정시킴에 따라 차체의 강성을 높이고, 크로스멤버의 설치작업성을 높일 수 있게 한 것을 목적으로 한다.The present invention has been made in order to solve the conventional problems as described above, by inserting a cross member for supporting the rear floor provided in the rear of the vehicle to the fixing portion formed in the rear frame to be fixed to the bottom surface of the rear frame The purpose is to increase the rigidity of the body and to improve the workability of the crossmembers.

차량의 리어플로어(6)를 지지고정하여 차체의 강성을 높일 수 있게 한 크로스멤버(1)가 리어프레임(3)에 고정설치된 것에 있어서, 상기 리어프레임(3)의 일측면 소정위치를 절결시켜 고정부(4)를 형성하고, 고정부(4)에는 크로스멤버(1)의 단부를 삽착시키며, 크로스멤버(1)의 단부에 형성된 플랜지(2)를 리어프레임(3)의 일측면과 하부면에 접촉되어 용접고정된 것이다.In the case where the cross member 1 fixed to the rear frame 3 is fixed to the rear frame 3 so as to support and secure the rear floor 6 of the vehicle, the predetermined position of one side of the rear frame 3 is cut out. Forming the front part (4), the end of the cross member (1) is inserted into the fixing portion (4), and the flange (2) formed at the end of the cross member (1) on one side and the bottom surface of the rear frame (3) It is fixed by welding in contact with.
이와같이된 본 발명의 일실시예를 첨부도에 의해 상세하게 설명하면 다음과 같다.One embodiment of the present invention thus described will be described in detail with reference to the accompanying drawings.
도 1은 본 발명의 적용상태도이고, 도 2는 본 발명의 사시도로서, 차체의 후방측에 구비된 리어플로어(6)의 하부면에 차량진행 방향측으로 리어프레임(3)이 구비된다.1 is an application state diagram of the present invention, Figure 2 is a perspective view of the present invention, the rear frame 3 is provided on the lower surface of the rear floor 6 provided on the rear side of the vehicle body toward the vehicle traveling direction.
상기 리어프레임(3)은 요철형태로 되어 그 상부 양측이 플랜지(5)가 형성되고, 이 플랜지(5)를 리어플로어(6)의 하부면에 접촉시켜 용접고정시킨다.The rear frame 3 has a concave-convex shape, and flanges 5 are formed at both upper sides thereof, and the flange 5 is brought into contact with the lower surface of the rear floor 6 to fix the weld.
상기 리어프레임(3)의 일측면 소정위치에는 절결부로된 고정부(4)를 형성하고, 이 고정부(4)에 교차방향으로 구비되는 크로스멤버(1)의 단부를 삽착시킨 상태에서 크로스멤버(1)의 단부에 형성된 플랜지(2)를 리어프레임(3)의 측면과 하부면에 용접고정시키고, 크로스멤버(1)의 상부는 리어플로어(6)의 하부면과 용접고정시킨다.At a predetermined position on one side of the rear frame 3, a fixing portion 4 formed of a cutout is formed, and the end portion of the cross member 1 provided in the cross direction is inserted in the fixing portion 4 in a state where the cross is inserted. The flange 2 formed at the end of the member 1 is welded to the side and bottom surface of the rear frame 3, and the upper portion of the cross member 1 is welded to the lower surface of the rear floor 6.
이와같이된 본 발명의 효과를 설명하면 다음과 같다.The effects of the present invention thus described are as follows.
차체의 리어플로어(6) 하부면에 고정설치된 크로스멤버(1)의 단부가 리어프레임(3)의 일측면에 형성된 고정부(4)에 삽착된 상태에서 리어프레임(3)의 하부면과 일측면에 접촉된 크로스멤버(1)의 플랜지(2)를 용접고정함에 따라 크로스멤버(1)가 리어프레임(3)에 견고하게 고정설치된다.The end of the cross member 1 fixed to the lower surface of the rear floor 6 of the vehicle body is fixed to the lower surface of the rear frame 3 in a state where the end of the cross member 1 is inserted into the fixing part 4 formed on one side of the rear frame 3. As the flange 2 of the cross member 1 in contact with the side is fixed by welding, the cross member 1 is firmly fixed to the rear frame 3.
또한 크로스멤버(1)는 리어프레임(3)에 형성된 고정부(4)에 설치됨에 따라 조립위치 셋팅이 용이하여 조립작업시 오차발생 방지에 따른 품질신뢰도를 높인다.In addition, the cross member 1 is installed on the fixing part 4 formed on the rear frame 3, so that the assembly position can be easily set, thereby increasing the quality reliability of preventing errors during assembly work.
따라서, 크로스멤버(1)와 리어프레임(3)과의 고정 견고성으로 차체의 강성을 높이고, 충돌 성능과 N.V.H(노이즈 바이브레이션 하시니스) 성능을 향상시킬 수 있는 것이다.Therefore, the rigidity of the vehicle body can be improved by the fixed rigidity between the cross member 1 and the rear frame 3, and the collision performance and N.V.H (noise vibration harmony) performance can be improved.
이상에서와 같이 본 발명은 차량의 후방에 구비된 리어플로어를 지지고정하는 크로스멤버를 리어프레임에 형성된 고정부로 삽입시켜 바닥면에 고정시킴에 따라 차체의 강성을 높이고, 리어크로스멤버의 설치작업성을 향상시키며, 차체의 충돌성능과 N.V.H 성능 향상으로 품질신뢰도를 높일 수 있는 효과가 있다.As described above, the present invention improves the rigidity of the vehicle body by inserting a cross member supporting the rear floor provided at the rear of the vehicle into the fixing part formed in the rear frame and fixing it to the bottom surface, and installability of the rear cross member. It improves the quality reliability by improving the collision performance and NVH performance of the body.
