Abstract

PURPOSE: Structure for assembling a bolt is provided to prevent loosening of the bolt by securing assembling torque of the bolt with fixing an insert pipe between an upper plate and a lower plate of a rear cross member through a flange. CONSTITUTION: A bolt assembling system is composed of an insert pipe(5) inserted between a first plate(1) and a second plate and composed of a flange; an assembling groove formed in the flange of the insert pipe; and an assembling projection fitted to the assembling groove and formed in the second plate. The end of the insert pipe is welded into the first plate, and a bolt(11) is combined with penetrating the first plate, the second plate and the insert pipe. Assembling torque is improved in tightening the bolt by fixing the first plate and the second plate of a rear cross member with the insert pipe firmly. Loosening of the bolt is restricted in vibrating a rear roll bracket during traveling on the rough road.

Description

볼트 체결구조{BOLTING STRUCTURE}Bolt fastening structure {BOLTING STRUCTURE}

본 발명은 엔진과 변속기 등으로 이루어지는 파워트레인을 엔진룸 내에서 마운트로 지지하기 위해 사용되는 리어롤브라켓을 리어크로스멤버에 설치하는 구조에 관한 것으로서, 보다 상세하게는 상기 리어롤브라켓을 리어크로스멤버에 볼트로 체결하는 구조에 관한 것이다.The present invention relates to a structure in which a rear roll bracket, which is used to support a power train composed of an engine and a transmission, etc. as a mount in an engine room, is installed in a rear cross member. More specifically, the rear roll bracket is a rear cross member. To a structure that is fastened with bolts.

도 1에는 종래에 리어롤브라켓(100)이 사용되고 있는 상태를 설명하고 있는 것으로서, 엔진에 연결된 변속기(102)가 차량의 전방과 후방에 위치한 마운트(104)에 의해 서브프레임(106)에 지지되고 있다.1 illustrates a state in which the rear roll bracket 100 is conventionally used, and the transmission 102 connected to the engine is supported on the subframe 106 by mounts 104 located at the front and rear of the vehicle. have.

여기서, 차량의 후방에 위치한 마운트(104)는 상기 리어롤브라켓(100)에 의해 서브프레임(106)의 리어크로스멤버(108)에 결합되어 있는데, 그 상세한 구조는 도 2에 도시된 바와 같다.Here, the mount 104 located at the rear of the vehicle is coupled to the rear cross member 108 of the subframe 106 by the rear roll bracket 100, the detailed structure of which is shown in FIG.

즉, 상기 리어롤브라켓(100)은 상판(110)과 하판(112)으로 이루어진 리어크로스멤버(108)를 관통하여 결합되는 볼트(114)에 의해 체결되어 있는 것이다.That is, the rear roll bracket 100 is fastened by a bolt 114 coupled through the rear cross member 108 formed of the upper plate 110 and the lower plate 112.

도 3에는 상기 리어롤브라켓(100)을 리어크로스멤버(108)에 체결하는 볼트(114)의 체결구조를 도시하고 있는바, 상기 리어크로스멤버(108)를 구성하는 상판(110)과 하판(112)의 사이에 강성확보를 위한 인서트파이프(116)를 구비하고 있다. 상기 인서트파이프(116)를 설치하는 방법은, 도시된 바와 같이 상기 인서트파이프(116)를 상판(110)의 하측에 용접에 의해 결합한 후, 상기 상판(110)과 하판(112)을 결합하여 완성하며, 여기서, 상기 하판(112)과 인서트파이프(116) 사이에는 구조적으로 별도의 용접을 하지 못하게 된다.3 shows the fastening structure of the bolt 114 for fastening the rear roll bracket 100 to the rear cross member 108. The upper plate 110 and the lower plate constituting the rear cross member 108 are shown in FIG. An insert pipe 116 is provided between the 112 to secure rigidity. A method of installing the insert pipe 116 is completed by joining the insert pipe 116 to the lower side of the upper plate 110, as shown, by combining the upper plate 110 and the lower plate 112. In this case, the lower plate 112 and the insert pipe 116 is structurally prevented from welding separately.

따라서, 상기 인서트파이프(116)와 하판(112)의 사이에는 리어크로스멤버(108)의 조립성 등을 고려한 간격이 존재하게 되는데, 이 간격은 상기 리어롤브라켓(100)을 고정하기 위한 볼트(114)의 체결시에 체결토크의 저하를 가져오게 되며, 이러한 체결토크의 저하는 가혹조건의 도로를 주행하는 경우나 큰 구동반발력이 작용하게 되는 경우에 상기 리어롤브라켓(100)을 가진시켜서 결국 볼트(114)가 풀어지게 하는 문제를 가지고 있다.Therefore, there is a gap between the insert pipe 116 and the lower plate 112 in consideration of the assemblability of the rear cross member 108, the gap is a bolt for fixing the rear roll bracket (100) 114), the tightening torque is lowered, and the lowering of the tightening torque causes the rear roll bracket 100 to be exerted when driving on a road under severe conditions or when a large driving repulsion force is applied. There is a problem that the bolt 114 is released.

이에 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 리어크로스멤버의 상판과 하판 사이에 개재되는 인서트파이프를 보다 견고하게 고정하여 볼트의 체결시 충분한 체결토크의 확보를 가능하게 함으로써 볼트의 풀림현상을 방지할 수 있도록 한 볼트 체결구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the problems as described above, by more firmly fixing the insert pipe interposed between the upper and lower plates of the rear cross member bolts to secure sufficient tightening torque when tightening the bolts The purpose is to provide a bolted structure to prevent the loosening phenomenon.
