It is about changing the coupling structure.
자동차의 후방 하부 차체에 위치한 트레일링암의 결합구조를 도1 및 도2를 참조하여 살펴보면, 차체의 측부를 이루는 양측 사이드실(1)의 후방측에 차체를 가로지르는 제3크로스부재(2)가 설치되어 있다. 또한, 상기 제3크로스부재(2)의 전방에는 차체의 중앙부를 지지하는 한 쌍의 언더프레임(3)이 나란하게 설치되어 있다.Looking at the coupling structure of the trailing arms located on the lower rear body of the vehicle with reference to Figures 1 and 2, the third cross member (2) across the vehicle body on the rear side of both side seals 1 forming the side of the vehicle body It is installed. In addition, in front of the third cross member 2, a pair of underframes 3 supporting the central portion of the vehicle body are provided side by side.
상기 제3크로스부재(2)의 후방 측에는 차체의 후방부를 지지하는 리어사이드멤버(4)가 차체 양측면에 각각 설치되어 있고, 상기 양측 리어사이드멤버(4)의 중앙부에는 제4크로스부재(5)가 가로질러 설치되어 있다. 참고로 제1크로스부재와 제2크로스부재는 차체의 전방측에 설치되어 있어서 도면에는 나타나지 않았다.On the rear side of the third cross member 2, rear side members 4 supporting the rear portion of the vehicle body are respectively provided on both side surfaces of the vehicle body, and the fourth cross member 5 is disposed at the center of the both rear side members 4, respectively. Is installed across. For reference, the first cross member and the second cross member are provided in the front side of the vehicle body, and thus are not shown in the drawings.
여기서, 상기 리어사이드멤버(4)의 외측으로 자동차의 뒷바퀴(6)가 설치되어 있는데, 상기 뒷바퀴(6)로부터 전달되는 진동을 줄이고 승차감을 향상시키기 위하여 트레일링암(7) 타입의 현가장치가 마련된다.Here, the rear wheel 6 of the vehicle is provided to the outside of the rear side member 4, the trailing arm (7) type suspension device is provided to reduce the vibration transmitted from the rear wheel (6) and improve the riding comfort do.
상기 트레일링암(7)은 뒷바퀴(6)와 리어사이드멤버(4) 사이에 설치되며, 마운팅브래킷(8)을 매개로 상기 리어사이드멤버(4)의 하부에 힌지 결합된다.The trailing arm 7 is installed between the rear wheel 6 and the rear side member 4 and is hinged to the lower portion of the rear side member 4 via a mounting bracket 8.
상기 트레일링암(7)의 결합구조를 도2를 참조하여 보다 자세하게 설명하면, 차체 후방 측부를 이루는 사이드실(1)의 안쪽 상부에 배치된 리어사이드멤버(4)의 하부에는 트레일링암(7)이 결합되기 위한 마운팅브래킷(8)이 볼트(b)를 매개로 체결되고, 상기 마운팅브래킷(8)에는 트레일링암(7)이 유동 가능하도록 힌지핀(9)을 매개로 연결된다.The coupling structure of the trailing arm 7 will be described in more detail with reference to FIG. 2. The trailing arm 7 is disposed below the rear side member 4 disposed in the upper part of the side chamber 1 forming the rear side of the vehicle body. The mounting bracket 8 to be coupled is fastened via the bolt b, and the mounting bracket 8 is connected via a hinge pin 9 to enable the trailing arm 7 to flow.
그러나, 이상과 같은 종래의 트레일링암 결합구조는 트레일링암을 장착하기 위한 마운팅브래킷이 리어사이드멤버의 하부에 결합되므로 그 결합부가 트레일링암으로부터 전달되는 상하방향인 종방향의 하중에는 비교적 강한 구조를 보이게 되지만, 횡방향으로 가해지는 하중에는 매우 취약하여 소음진동이 많이 발생하고 심한 경우 그 결합부가 파단되는 문제점이 있다.However, in the conventional trailing arm coupling structure as described above, since the mounting bracket for mounting the trailing arm is coupled to the lower side of the rear side member, the coupling portion shows a relatively strong structure against the vertical load in the vertical direction transmitted from the trailing arm. However, it is very vulnerable to the load applied in the transverse direction, there is a problem that a lot of noise vibration occurs and the joint is broken in severe cases.
본 발명은 상술한 바와 같은 문제점을 해결하기 위하여 제안된 것으로서, 그 목적은 리어사이드멤버에 결합되는 트레일링암의 결합구조를 변경하여 그 결합부가 종방향 하중뿐만 아니라 횡방향으로 전달되는 하중에 대해서도 잘 견딜 수 있도록 횡강성을 보강한 차체후방의 트레일링암 결합구조를 제공함에 있다.The present invention has been proposed in order to solve the above problems, the object of which is to change the coupling structure of the trailing arm coupled to the rear side member, so that the coupling portion is well applied not only to the longitudinal load but also to the transversely transmitted load. It is to provide a trailing arm coupling structure in the rear of the body reinforced with lateral rigidity to withstand.

이하, 본 발명을 첨부된 도3에 의거하여 설명한다.Hereinafter, the present invention will be described with reference to FIG.
도3은 본 발명에 따른 트레일링암 결합구조의 단면도로서, 트레일링암(7)은 주행시 뒷바퀴에 전달되는 진동이나 충격이 탑승자에게 전달되지 않도록 스프링(미도시)과 쇽업쇼버(미도시)가 설치되는 서스펜션의 일종으로, 차량에 있어서 주로뒷 현가장치에 많이 사용된다.Figure 3 is a cross-sectional view of the trailing arm coupling structure according to the present invention, the trailing arm 7 is a spring (not shown) and shock absorber (not shown) is installed so that the vibration or shock transmitted to the rear wheel during driving is not transmitted to the occupant As a kind of suspension, it is mainly used in the rear suspension of the vehicle.
자동차는 주행중 그 서스펜션에 다양한 형태의 하중이 가해지는데, 그 하중은 도로노면의 요철로부터 전해지는 상하방향의 하중인 종하중과, 차축방향으로 가해지는 횡하중으로 크게 구분된다. 특히 횡방향의 하중은 차량의 코너링시에 많이 발생된다.The vehicle is subjected to various types of loads on the suspension while driving, and the loads are largely divided into longitudinal loads, which are vertical loads transmitted from the unevenness of the road surface, and lateral loads applied in the axle direction. In particular, the load in the lateral direction is often generated at the corner of the vehicle.
따라서, 본 발명은 트레일링암(7)에 가해지는 횡방향 하중에 잘 견딜 수 있는 결합구조를 갖도록 도3에서와 같이 트레일링암 마운팅브래킷(11)이 리어사이드멤버(4)의 양측면과 저면에 용접 결합되고, 상기 리어사이드멤버(4) 및 마운팅브래킷(11)의 외측에 설치되는 사이드실(10)은 상기 리어사이드멤버(4) 및 마운팅브래킷(11)에 밀착되게 용접된다.Therefore, in the present invention, the trailing arm mounting bracket 11 is welded to both sides and the bottom of the rear side member 4 as shown in FIG. 3 so as to have a coupling structure that can withstand the lateral load applied to the trailing arm 7. A side seal 10 coupled to the rear side member 4 and the mounting bracket 11 is welded to closely contact the rear side member 4 and the mounting bracket 11.
또한, 상기 사이드실(10)과 상기 마운팅브래킷(11)이 접촉되는 접면부에는 상기 트레일링암(7)이 연결되도록 하는 연결핀(12)이 상기 사이드실(10) 및 마운팅브래킷(11)을 관통하여 설치된다.In addition, a connecting pin 12 for connecting the trailing arm 7 to the contact portion where the side seal 10 and the mounting bracket 11 are in contact with the side seal 10 and the mounting bracket 11. Installed through.
여기서, 상기 마운팅브래킷(11)은 도면에 도시된 바와 같이 상기 리어사이드멤버(4)의 양측면 및 저면의 3개 면에 용접되어 있고, 또한 마운팅브래킷(11)의 적어도 어느 일측은 측면에서부터 저면까지 감싸면서 결합되어 있으므로 보다 큰 종강성 및 횡강성을 갖게 된다.Here, the mounting bracket 11 is welded to three surfaces of both side surfaces and the bottom surface of the rear side member 4, as shown in the drawing, and at least one side of the mounting bracket 11 is from side to bottom Since they are wrapped together, they have greater longitudinal and lateral stiffness.
또한, 리어사이드멤버(4)와 마운팅브래킷(11)을 외측에서 커버하는 상기 사이드실(10)은 상기 리어사이드멤버(4) 및 마운팅브래킷(11)에 밀착되게 용접된다고 하였는데, 이때 상기 마운팅브래킷(11)의 일측은 상기 리어사이드멤버(4)를 감싸면서 용접된 관계로 그 부위가 리어사이드멤버(4)의 면보다 들어가 있다.In addition, the side seal 10 covering the rear side member 4 and the mounting bracket 11 from the outside is said to be welded in close contact with the rear side member 4 and the mounting bracket 11, the mounting bracket One side of (11) is welded while surrounding the rear side member (4), the part is entered than the surface of the rear side member (4).
그래서, 상기 사이드실(10)이 다른 부재와의 밀착성을 좋게 하고 용접작업이 편리하게 이루어지도록 상기 사이드실(10)이 상단부(10a)와 하단부(10b)로 분리되도록 하여, 상기 상단부(10a)는 상기 리어사이드멤버(4) 및 마운팅브래킷(11)과 3겹 용접되도록 하고, 상기 하단부(10b)는 상기 마운팅브래킷(11)의 일측면과 접면되어 용접된 후 트레일링암 결합용 연결핀(12)에 의하여 관통되어 상기 마운팅브래킷(11)과 다시 일체로 체결된다.Thus, the side seal 10 is separated into the upper end portion 10a and the lower end portion 10b so that the side seal 10 has good adhesion with other members and the welding operation is conveniently performed. Is welded to the rear side member 4 and the mounting bracket 11 in three layers, and the lower end 10b is in contact with one side of the mounting bracket 11 and welded to the trailing arm coupling connecting pin 12 Penetrated by) is again integrally fastened with the mounting bracket (11).
따라서, 상기와 같은 구조로 트레일링암(7)을 결합하면 트레일링암(7)이 마운팅브래킷(11)을 통해 상기 리어사이드멤버(4)의 측면과 저면에 동시 결합되므로 종래에 문제가 되던 횡방향 강성이 증대되며, 또한 사이드실(10)이 마운팅브래킷(11)과 일체로 결합되므로 트레일링암(7)의 횡방향 강성이 배가된다.Therefore, when the trailing arm 7 is coupled to the structure as described above, the trailing arm 7 is simultaneously coupled to the side and the bottom of the rear side member 4 through a mounting bracket 11, which is a problem in the past. The stiffness is increased, and since the side seal 10 is integrally coupled with the mounting bracket 11, the lateral rigidity of the trailing arm 7 is doubled.
상술한 바와 같이 본 발명에 따른 차체후방의 트레일링암 결합구조에 의하면, 트레일링암 마운팅브래킷이 리어사이드멤버의 측면과 저면에 각각 결합되고 또한, 사이드실과도 접면되어 용접된 후 트레일링암 체결용 연결핀을 통해 일체로 결합되어 횡방향 하중에 특히 강한 구조를 갖게 됨으로써 트레일링암 결합부의 내구성 및 진동소음 성능이 개선되는 특유의 효과가 있다.As described above, according to the trailing arm coupling structure of the rear of the vehicle body according to the present invention, the trailing arm mounting brackets are coupled to the side and bottom of the rear side member, and are also contacted with the side seal and welded to the trailing arm coupling pins. Through integrally coupled to have a particularly strong structure in the transverse load has the unique effect of improving the durability and vibration noise performance of the trailing arm coupling portion.
또한, 본 발명은 트레일링암의 결합구조만을 변경함으로서 횡방향 강성을 증대시키기 위한 별도의 보강부재가 추가되지 않으므로 부품절감 및 차체 경량화에 큰 효과가 있다.In addition, since the present invention does not add a separate reinforcing member to increase the lateral rigidity by changing only the coupling structure of the trailing arm, there is a great effect in reducing parts and weight of the vehicle body.
