일반적으로 섀시리어크로스멤버(Chassis Rear Cross Member)는, 쇽업소버와 연결되어 노면으로부터 전달되는 진동 및 충격을 흡수 또는 차체로 분산시킴은 물론, 크로스멤버와 더불어 하중을 지지하는 역할을 수행한다.In general, the chassis rear cross member is connected to the shock absorber to distribute vibrations and shocks transmitted from the road surface to the body or to support the load along with the cross member.
여기서, 상기 섀시리어크로스멤버(30)가 설치되는 차체의 골격은 도 1에 도시된 바와 같이 한쌍의 사이드멤버(10)와 이 사이드멤버(10)를 가로질러 결합되는 다수개의 크로스멤버(20)로 이루어져 있다.Here, the skeleton of the vehicle body in which the chassis rear cross member 30 is installed is a pair of side members 10 and a plurality of cross members 20 coupled across the side members 10 as shown in FIG. 1. Consists of
그리고, 상기 섀시리어크로스멤버(30)는 도 1에 도시된 바와 같이, 중간부위가 활의 모양과 같이 휘어지도록 형성되면서 양끝단이 한쌍의 사이드멤버(10)에 각각 고착되도록 된 제1결합멤버(31)와, 일단이 상기 제1결합멤버(31)의 중간부위에 고착되면서 타단이 제5크로스멤버(22)의 하부에 결합되도록 된 제2결합멤버(32)로 이루어져 있다.And, as shown in Figure 1, the chassis rear cross member 30, the first coupling member is formed so that the middle portion is bent in the shape of a bow, and both ends are fixed to the pair of side members 10, respectively. 31 and one end of the second coupling member 32 is fixed to the middle of the first coupling member 31 and the other end is coupled to the lower portion of the fifth cross member 22.
한편, 상기 섀시리어크로스멤버(30)의 제1결합멤버(31)와 제2결합멤버(32)의 결합구조를 도 1과 도 2를 참조로 자세히 설명하면, 상기 섀시리어크로스멤버(30)의 제1결합멤버(31)는 크로스멤버(30)의 아래쪽으로 위치된 상태에서 양끝단이 제4크로스멤버(21)가 고착되는 사이드멤버(10)의 소정부위에 각각 용접결합으로 고착되고, 상기 섀시리어크로스멤버(30)의 제2결합멤버(32)는 일단이 상기 제1결합멤버(31)의 중간부위에 용접결합으로 고착되면서 타단이 제5크로스멤버(22)의 하부에 밀착되어 보강판(40)과 동시에 결합되어 있다.Meanwhile, when the coupling structure of the first coupling member 31 and the second coupling member 32 of the chassis rear cross member 30 is described in detail with reference to FIGS. 1 and 2, the chassis rear cross member 30 is described.

여기서, 도 4에 도시된 미설명부호 A는 제1보강판(111)과 제1결합너트(120)의 용접부이고, B는 제1결합너트(120)와 제2보강판(140)의 용접부이며, C는 제1보강판(111)과 제2결합너트(130)의 용접부이고, D는 제2결합너트(130)와 제3보강판(150)의 용접부이다.Here, reference numeral A shown in FIG. 4 is a welded portion of the first reinforcing plate 111 and the first coupling nut 120, and B is a welded portion of the first coupling nut 120 and the second reinforcement plate 140. C is a welded portion of the first reinforcing plate 111 and the second coupling nut 130, D is a welded portion of the second coupling nut 130 and the third reinforcing plate 150.
이후, 상기 결합볼트(160)를 섀시리어크로스멤버(30)의 제2결합멤버(32)와제5크로스멤버(22) 및 제1보강판(110)의 제1,2관통구멍(111,113)으로 삽입시켜 제1,2결합너트(120,130)에 각각 체결시키게 되면, 본 발명의 보강장치(100)가 제2결합멤버(32)와 더불어 제5크로스멤버(22)의 소정부위에 단단히 조립되게 된다.Thereafter, the coupling bolt 160 to the first and second through holes 111 and 113 of the second coupling member 32 and the fifth cross member 22 and the first reinforcing plate 110 of the chassis rear cross member 30. When inserted and fastened to the first and second coupling nuts 120 and 130, respectively, the reinforcement device 100 of the present invention is firmly assembled to a predetermined portion of the fifth cross member 22 together with the second coupling member 32. .
따라서, 상기 섀시리어크로스멤버(30)의 제2결합멤버(32)가 본 발명의 보강장치(100)와 더불어 제5크로스멤버(22)에 설치되면, 주행중 노면으로부터 진동과 충격이 지속적으로 전달되더라도 상기 보강장치(100)는 항상 일정한 결합력을 유지하게 되므로, 전체적인 차체의 비틀림강성이 도 2에 도시된 종래의 구조보다 향상되게 되며, 이로인해 탑승자의 승차감도 종래의 구조보다 향상되게 된다.Therefore, when the second coupling member 32 of the chassis rear cross member 30 is installed in the fifth cross member 22 together with the reinforcement device 100 of the present invention, vibration and shock are continuously transmitted from the road surface while driving. Even if the reinforcement device 100 always maintains a constant coupling force, the torsional rigidity of the overall vehicle body is improved than the conventional structure shown in Figure 2, thereby improving the ride comfort of the passengers than the conventional structure.
이상 설명한 바와 같이 본 발명에 의하면, 섀시리어크로스멤버의 제2결합멤버가 다수개의 보강판 및 결합볼트와 결합너트로 이루어진 보강장치에 의해 제5크로스멤버에 설치되어져, 주행중 노면으로부터 진동과 충격이 지속적으로 전달되더라도 상기 보강장치의 결합력이 감소되는 것이 방지되므로 전체적인 차체의 비틀림강성이 향상될 뿐만 아니라, 이로인해 탑승자의 승차감도 향상되어 상품성이 증진되는 효과가 있다.As described above, according to the present invention, the second engagement member of the chassis rear cross member is installed on the fifth cross member by a reinforcement device composed of a plurality of reinforcement plates and coupling bolts and coupling nuts, so that vibrations and impacts from the road surface during driving are prevented. Even if continuously delivered, the coupling force of the reinforcement device is prevented from being reduced, thereby improving the torsional rigidity of the entire vehicle body, thereby improving the riding comfort of the occupant, thereby improving the productability.
