Description
본 고안은 자동차용 서브 프레임에 관한 것으로서, 상세하게는 구조를 간단히 하고 또 경량화한 것이다.The present invention relates to an automobile subframe, and in detail, the structure is simple and lightweight.
본건출원인은 일부를 하이드로포밍 형성하여 구조를 단순화, 경량화한 자동차용 서브 프레임에 대하여 이미 여러건을 제공한 바 있으며 이들중 가장 진보된 것으로서 실용신안등록 제239855호를 예로 들 수가 있다.The present applicant has already provided a number of sub-frames for automobiles which have been partially hydroformed to simplify and lighten the structure, and the most advanced among them is Utility Model Registration No. 239855.
이는 프론트멤버와 사이드멤버의 일부를 하이드로포밍 형성하고 여기에 사이드멤버의 일부를 포함하도록 블랭킹가공 형성되는 리어멤버 앗세이를 일부중첩되게 하여 볼트넛으로 연결구성하여서 된 것이다.This is to form a hydroforming part of the front member and the side member, and the rear member assembly formed by blanking processing to include a part of the side member is partially overlapped with bolt nuts.
따라서 사이드멤버의 일부를 포함하는 리어멤버 앗세이와 연결수단등으로 인한 복잡한 구성으로 제작비용이 많이 소요되고 또 블랭킹가공되는 일부 사이드멤버와 이를 연결하기 위한 중첩부 및 연결수단인 볼트넛등으로 인하여 상당한 무게가 가중되므로 연비향상을 기대할 수가 없는 등의 문제점들이 있는 것이다.Therefore, due to the complicated configuration due to the rear member assembly and the connecting means including a part of the side member, the production cost is high, and some side members are blanked and the overlapping part and the connecting means for connecting the bolt nuts are used. There is a problem that can not be expected to improve fuel economy because of the weight is considerable.
본 고안의 목적은 구성을 간단히 하여 제작비용을 절감하고 또 경량화로 연비를 향상시켜 줄 수가 있는 자동차용 서브 프레임을 제공하는데 있다.An object of the present invention is to provide a sub-frame for automobiles that can simplify the configuration and reduce the production cost and improve the fuel economy by light weight.
본 고안은 목적달성을 위하여 프론트멤버로부터 완전한 골격을 갖는 사이드멤버가 연장형성되도록 본체를 하이드로포밍 형성하고 리어멤버 앗세이는 사이드멤버 사이에 용접고정하여 구성함을 특징으로 한다.The present invention is characterized in that the main body is hydroformed to form a side member having a complete skeleton from the front member to form and the rear member assembly is configured by welding between the side members.

도 1은 본 고안의 분해사시도로서, 본 고안은 하이드로포밍(Hydro-Forming) 형성되는 본체(2)와 상기 본체(2)에 연결형성되는 브라켓(4)(6)과 아암연결부(8) (10) 및 연결구(12)(14)와 본체(2)의 사이드멤버(Side Member)(16)(18) 사이에 연결고정되는 리어멤버 앗세이(Rear Member Ass'y)(20)로 구성된다.1 is an exploded perspective view of the present invention, the present invention is a hydroformed (Hydro-Forming) formed body (2) and the bracket (4) (6) and the arm connecting portion (8) formed to be connected to the body (2) 10) and a Rear Member Ass'y (20) secured to be connected between the connector (12) 14 and the Side Member (16) (18) of the main body (2). .
하이드로포밍 형성되는 본체(2)는 프론트멤버(Front Member)(22)로부터 완전한 골격을 갖는 사이드멤버(16)(18)가 연장형성되어 구성된다.The body 2 to be formed hydroforming is formed by extending the side members (16, 18) having a complete skeleton from the front member (22).
리어멤버 앗세이(20)는 철판을 블랭킹가공 형성하여 상하분리제작한 다음 본체(2)의 사이드멤버(16)(18) 사이에 용접고정해 주므로서 완전한 형태의 서브 프레임(A)을 구성하게 되는 것이다.The rear member assembly 20 is formed by blanking the steel plate to manufacture the upper and lower parts, and then welds between the side members 16 and 18 of the main body 2 to form a complete subframe A. Will be.
본 고안은 하이드로포밍 형성되는 본체(2)는 프론트멤버(22)로부터 완전한 골격의 사이드멤버(16)(18)가 연장형성되는 것으로서 여기에 차체와 연결되는 브라켓(4)(6)과 연결구(12)(14) 및 로암을 연결하는 아암연결부(8)(10)를 용접고정하고 사이드멤버(16)(18) 사이에 리어멤버 앗세이(20)를 용접고정하는 것으로 완전한 형태의 서브 프레임(A)을 구성하게 된다.According to the present invention, the main body 2, which is formed hydroforming, is formed by extending the side members 16 and 18 of the complete skeleton from the front member 22, and the brackets 4 and 6 connected to the vehicle body and the connector ( 12) (14) and the arm connecting portions (8) and (10) connecting the low arm by welding and fixing the rear member assembly (20) between the side members (16, 18) to form a complete subframe ( A) will be constructed.
따라서 사이드멤버(16)(18)의 전체적인 골격은 프론트멤버(22)와 함께 하이드로포밍 형성되고 또 상기 사이드멤버(16)(18) 사이에 리어멤버 앗세이(20)가 용접고정되므로 구성을 간단히 할 수가 있게 된다.Therefore, the overall skeleton of the side members 16 and 18 is hydroformed together with the front member 22, and the rear member assembly 20 is welded and fixed between the side members 16 and 18 to simplify the configuration. I can do it.
또한 사이드멤버(16)(18)의 기본골격이 하이드로포밍 형성되는만큼 경량화할 수가 있고 또 리어멤버 앗세이(20)와의 연결시 중첩부분이 크지 않아 그에 따른 경량화도 기대할 수가 있게 되는 것이다.In addition, as the basic skeleton of the side members (16) and (18) can be reduced in weight as the hydroforming is formed, and when the connection with the rear member assembly (20) does not have a large overlapping portion can be expected to be lighter accordingly.
이와 같이 본 고안은 하이드로포밍 형성되는 본체(2)가 프론트멤버(22)와 사이드멤버(16)(18) 전체를 포함하도록 하고 또 사이드멤버(16)(18) 사이에 리어멤버 앗세이(20)를 용접구성하므로서 구조의 단순화로 제작비용을 절감할 수가 있고, 프론트멤버와 함께 사이드멤버(16)(18) 전체가 하이드로포밍 형성되고 리어멤버 앗세이(20)의 용접고정으로 중첩부분을 최소화할 수가 있어 경량화로 연비향상을 기대할 수가 있게 되는 것이다.As such, the present invention allows the body 2 to be hydroformed to include the entire front member 22 and the side members 16 and 18, and the rear member assembly 20 between the side members 16 and 18. The welding structure can reduce the manufacturing cost by simplifying the structure, and the entire side members 16 and 18 are hydroformed together with the front members, and the overlapping portion is minimized by welding the rear member assembly 20. As a result, it is possible to expect fuel efficiency improvement by being lightweight.
