본 발명은 사이드 멤버에 관한 것으로서, 보다 상세하게는 4륜 구동 차량에서 새시를 지지하는 사이드 멤버에 관한 것이다.The present invention relates to a side member, and more particularly to a side member for supporting the chassis in a four-wheel drive vehicle.

일반적으로, 자동차의 바디는 승용차의 경우 모노코크 바디를 사용함과 아울러 여기에 도어, 트렁크 리드, 후드, 루프 등을 부착하여 구성하게 되고, 상용차 또는 비포장 도로를 주행하는 4륜 구동 차량 등은 X 자형 프레임에 도어, 루프 등을 부착하여 구성하게 된다.In general, the body of the car uses a monocoque body in the case of a passenger car and attaches a door, a trunk lid, a hood, a roof, etc. to the vehicle, and a four-wheel drive vehicle driving a commercial vehicle or an unpaved road is an X-shaped frame. A door, a roof, etc. are attached to the structure.

특히, 4륜 구동 차량은 비포장 도로 등 험로를 자주 주행하게 되는 바, 주행시의 충격에 견딜 수 있도록 높은 바디 강성을 요구하게 된다.In particular, the four-wheel drive vehicle frequently travels a rough road such as an unpaved road, and thus requires a high body rigidity to withstand the impact of driving.

즉, 노면의 요철에 의해 바디가 비틀림 응력 및 충격력을 받을 때 이를 완벽하게 견뎌야 하는 바, 이를 위해 제3도에 도시된 바와 같이 바디의 저면을 이루는 사이드 멤버(50)와, 상기 사이드 멤버(50)를 연결함과 아울러 새시 각 부품을 지지하게 되는 크로스 멤버(51)로 바디의 저면이 구성되어 있게 된다.That is, when the body is subjected to torsional stress and impact force by the unevenness of the road surface, it must be perfectly endured. For this, the side member 50 forming the bottom of the body and the side member 50 as shown in FIG. ) And the bottom surface of the body is composed of a cross member 51 to support the chassis each component.

여기서, 상기한 사이드 멤버(50) 및 크로스 멤버(51)는 여기에 지지되는 새시 부품의 중량이 비교적 무겁기 때문에 새시 부품의 하중뿐만 아니라 충격력과 비틀림 응력을 견딜 수 있도록 구성되어 있게 된다.Here, the side member 50 and the cross member 51 is configured to withstand the impact force and torsional stress as well as the load of the chassis part because the weight of the chassis part supported there is relatively heavy.

특히, 자동차 새시중 어퍼 아암, 쇽 업소버 등이 부착되는 사이드 멤버의 중간 부분은 실질적으로 노면으로부터의 충격을 직접받게 되는 바, 이를 지지하기 위해 제4도에 도시된 바와 같이 아우터 멤버(52)와, 상기한 아우터 멤버(52)와 밀착되도록 제1 굽힘부(53)가 형성되고 저면에 폐공간(54)을 형성하도록 제2 굽힘부(55)가 형성된 인너 멤버(56)로 구성되어 있다.In particular, the middle portion of the side member to which the upper arm, shock absorber, etc. of the automobile chassis is attached is substantially subjected to direct impact from the road surface, and as shown in FIG. 4 to support the outer member 52, In addition, the first bent portion 53 is formed to be in close contact with the outer member 52, and the inner member 56 is formed with the second bent portion 55 formed to form the closed space 54 at the bottom.

또한, 상기한 제2 굽힘부(55)를 감싸고 아우터 멤버(52)와 저면이 밀착된 보강재(57)가 제2 굽힘부(55) 외주에 부착되어 있고, 상기한 보강재(57)의 내부 저면에 보조 보강재(58)가 부착되어 있게 된다.In addition, a reinforcing material 57 surrounding the second bending part 55 and having the outer member 52 and the bottom contacted thereto is attached to the outer circumference of the second bending part 55, and the inner bottom of the reinforcing material 57 described above. The auxiliary reinforcing material 58 is attached to this.

상기한 바와 같은 구성에서 아우터 멤버(52)에 고정되는 쇽 업소버 등과 같은 새시는 아우터 멤버(52)에 하중을 집중시키게 된다.In the configuration as described above, the chassis such as shock absorbers fixed to the outer member 52 concentrates the load on the outer member 52.

아우터 멤버(52)에 하중이 집중되면 상기한 인너 멤버(56)와 용접되어 있는 부분에 하중P이 집중되면서 분산되어 이를 흡수하게 되는 것이다.When the load is concentrated in the outer member 52, the load P is concentrated in the portion welded to the inner member 56 while being dispersed and absorbed.

그러나, 상기한 바와 같이 인너 멤버와 아우터 멤버의 결합부분에 하중이 집중되면 상기한 하중이 이를 분리시키는 힘으로 작용하게 됨으로써 피로 누적시 인너 멤버와 아우터 멤버가 분리되는 문제점이 있다.However, if the load is concentrated in the coupling portion of the inner member and the outer member as described above, there is a problem that the inner member and the outer member are separated during the fatigue accumulation by acting as a force for separating the load.

따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 아우터 멤버와 인너 멤버의 결합 부분 강성을 증대시킴으로써 피로 누적에 의한 인너, 아우터 멤버 분리를 방지할 수 있는 4륜 구동 차량의 사이드 멤버를 제공함에 있다.Accordingly, an object of the present invention is to solve the above problems, and by increasing the coupling part rigidity of the outer member and the inner member, the side member of the four-wheel drive vehicle which can prevent the inner and outer member separation due to the accumulation of fatigue is prevented. In providing.

상기한 목적을 실현하기 위하여 본 발명은 인너, 아우터 멤버가 결합하여 구성된 4륜 구동 차량의 사이드 멤버에서 비틀림 응력에 대해 직교하도록 돌출부가 형성된 보강재를 인너, 아우터 멤버와 보조 보강재가 구성되는 공간의 내부에 삽입하여 구성한다.In order to achieve the above object, the present invention provides a reinforcement formed with a protrusion so as to be orthogonal to torsional stress in a side member of a four-wheel drive vehicle configured by combining an inner and an outer member. Insert it in to configure.

이하, 첨부도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

제1도와 제2도는 본 발명에 따른 4륜 구동 차량의 사이드 멤버를 도시한 주요부 분해 사시도와 조립 단면도로서, 비틀림 응력에 대해 직교하도록 돌출부(1)가 형성된 보강재(2)가 인너, 아우터 멤버(56, 52)와 보조 보강재(58)가 구성하는 공간의 내부에 삽입되어 있다.1 and 2 are an exploded perspective view and an assembled sectional view of an essential part showing a side member of a four-wheel drive vehicle according to the present invention, wherein the reinforcing member 2 in which the protrusion 1 is formed so as to be orthogonal to the torsional stress is inner or outer member ( 56 and 52 and the auxiliary reinforcing material 58 are inserted into the space constituting.

즉, 인너 멤버(56)와 보조 보강재(58)에 밀착된 상태에서 이와의 사이에 돌출부(1)가 공간부를 형성하여 비틀림 응력 강성을 향상시키게 되는 것이다.That is, in the state in which it is in close contact with the inner member 56 and the auxiliary reinforcement 58, the protrusion 1 forms a space therebetween, thereby improving the torsional stress stiffness.

상기한 바와 같은 본 발명의 작용 효과를 설명하면 4륜 구동 차량이 비포장 도로를 주행하게 되면 타이어로부터의 충격이 현가 장치와 이를 지지하는 사이드 멤버(50)에 전달된다.Referring to the operation and effect of the present invention as described above, when the four-wheel drive vehicle travels on the unpaved road, the shock from the tire is transmitted to the suspension device and the side member 50 supporting it.

즉, 상기한 현가 장치의 쇽 업소버 등이 부착되어 있는 사이드 멤버(50)의 아우터 멤버(52)에 충격력이 전달된다.That is, the impact force is transmitted to the outer member 52 of the side member 50 to which the shock absorber or the like of the suspension device is attached.

아우터 멤버(52)에 충격력이 전달되면 상기한 인너, 아우터 멤버(56, 52)를 분리시키는 비틀림 응력P으로 작용하게 되는 바, 상기한 힘P은 보강재(2)를 파손시키는 힘으로 작용하게 된다.When the impact force is transmitted to the outer member 52, the inner and outer members 56 and 52 act as a torsional stress P that separates the bar, and the force P acts as a force to break the reinforcing material 2. .

즉, 비틀림 응력이 인너, 아우터 멤버(56, 52)의 사이에 개재된 보강재(2)를 압축 및 분리시키는 힘으로 작용하게 되는 바, 상기한 힘은 돌출부(1)가 상기한 힘에 대해 직교한 상태를 유지하게 됨으로써 이 부분에서 흡수된다.That is, the torsional stress acts as a force for compressing and separating the reinforcing material 2 interposed between the inner and outer members 56 and 52, and the force is perpendicular to the force described above by the protrusion 1. It is absorbed in this part by maintaining a state.

상기한 보강재(2)에 의해 비틀림 응력이 분산 및 감소되면 비틀림 응력이 인너, 아우터 멤버(56, 52)에 작용하여도 이를 파손시키지 못하게 된다.When the torsion stress is dispersed and reduced by the reinforcing material 2, the torsion stress may not be damaged even when the torsion stress acts on the inner and outer members 56 and 52.

즉, 사이드 멤버(50)에 인가되는 하중을 보강재(2)가 1차 흡수하게 됨으로써 인너, 아우터 멤버(56, 52)의 파손을 방지할 수 있게 되는 것이다.That is, since the reinforcing material 2 is primarily absorbed by the load applied to the side member 50, it is possible to prevent the inner and outer members 56 and 52 from being damaged.

보강재(2)에 의해 사이드 멤버(50)의 파손이 방지되면 4륜 구동 차량의 비포장 도로 주행시 충격 등에 의한 쇽 업소버의 특성 변화 등을 방지할 수 있게 되는 것이다.When the side member 50 is prevented from being damaged by the reinforcing material 2, it is possible to prevent the shock absorber from changing the characteristics of the shock absorber due to the impact of the four-wheel drive vehicle on the off-road road.

이상과 같이 본 발명은 4륜 구동 차량의 사이드 멤버를 구성하는 인너, 아우터 멤버의 사이에 돌출부가 형성된 보강재를 부착함으로써 충격에 의한 인너, 아우터 멤버의 분리를 방지할 수 있는 잇점이 있는 것이다.As described above, the present invention has an advantage of preventing separation of the inner and outer members due to impact by attaching a reinforcing member having a protrusion formed between the inner and outer members constituting the side member of the four-wheel drive vehicle.
