Description

자동차 트레일러암의 결합구조Combination Structure of Automobile Trailer Arm

본 발명은 자동차의 차체 후단부에 결합되는 트레일러암( trailer arm)의 결합구조에 관한 것으로서, 트레일러암이 리어플로어(rear floor)에 결합되도록 구성하여 조립시 리어플로어와의 간섭을 피하고, 지면과의 여유공간을 확보하므로 설치작업이 용이하도록 하는 것이다.The present invention relates to a coupling structure of a trailer arm coupled to a rear end of a vehicle, and configured to be coupled to a rear floor so as to avoid interference with a rear floor when assembling the trailer arm. It is to make the installation work easier by securing the free space.

일반적으로 견인기구가 부착되는 자동차는 차체의 저면을 이루는 플로어판넬의 저면 양쪽에 소정 간격을 두고 하부로 돌출되는 론지가 입체형상으로 결합되어, 상기 양측 론지의 후단부쪽에 트레일러암이 취부되어 있다.In general, a vehicle to which a traction mechanism is attached is provided with a rouge projecting downward at a predetermined interval on both sides of a floor panel constituting the bottom of the vehicle body in a three-dimensional shape, and a trailer arm is mounted on the rear end of both sides of the ronge.

여기에서, 종래 자동차의 트레일러암은 제1도에 도시되는 바와 같아, T자형으로 토우바(41)가 형성되고, 토우바(41)의 중앙 연장부에 트레일러를 연결하기 위한 토잉볼(40)이 결합되며, 투오바(41)의 양측 단부에 각기 상부로 절곡 연장되는 고정판(39)이 일체로 결합되어 있다. 또한, 토우바(41) 중앙의 연장부는 소정각도 상향으로 절곡 연장고, 양측단부의 고정판(39)은 각기 상단에 평면부가 형성되어 상기 평면부에 차체와 결합을 관통구멍들이 형성되어 있다.Here, the trailer arm of the conventional vehicle is shown in Figure 1, the tow bar 41 is formed in a T-shape, the towing ball 40 for connecting the trailer to the central extension of the tow bar 41 These are combined, the fixing plate 39, which is bent and extended upwards, respectively, at both ends of the touva 41 are integrally coupled. In addition, the extension portion of the center of the tow bar 41 is bent upward by a predetermined angle, and the fixing plates 39 at both ends are formed with flat portions at upper ends thereof, and through holes are formed in the flat portions and coupled with the vehicle body.

이와같이 구성되는 종래 자동차의 트레일러암은 제2도에 도시되는 바와 같이, 토우바(41) 양측단부의 고정판(39)이 관통구멍을 통해 삽입되어 리어론지(35) 및 리어플로어판넬(34)을 관통하는 관통볼트(38)들에 의해 결합된다.As shown in FIG. 2, the trailer arm of the conventional vehicle configured as described above has the fixing plates 39 at both ends of the tow bar 41 inserted through the through holes, so that the rear lock 35 and the rear floor panel 34 can be removed. It is coupled by penetrating through bolts 38.

한편, 트레일러암의 결합구조는 토우바(41) 양단의 고정판(39) 상면이 리어론지(35)의 저면에 밀착시되고, 리어플로어판넬(34)의 상면에 브라켓(33)이 부착되며, 리어론지(35)의 내부쪽에 스페이서(36)가 내장되어, 와셔(32)를 사이에 두고 토우바(41)의 관통구멍으로 삽입되는 관통볼트(38)가 스페이서(36)오 리어플로어판넬(34) 및 브라켓(33)을 관통하여 와셔(32)를 사이에 투고 고정너트(31)에 체결되었다.On the other hand, the coupling structure of the trailer arm when the upper surface of the fixing plate 39 on both ends of the tow bar 41 is in close contact with the bottom of the rear longage 35, the bracket 33 is attached to the upper surface of the rear floor panel 34, The spacer 36 is built into the rear longage 35 so that the through bolt 38 inserted into the through hole of the tow bar 41 with the washer 32 therebetween is provided with a spacer 36 or a rear floor panel ( 34) and the washer 32 was fastened to the fixing nut 31 by the washer 32.

이러한 종래 트레일러암의 결합구조는 양측 고정판(39)이 차체의 리어론지(35)에 결합되어 토잉볼(40)에 의해 트레일러를 견인하도록 하며, 견인시 토잉볼(40)에 작용되는 하중이 토우바(41) 양측의 고정판(39)을 통해 리어론지(35)와 리어플로어판넬(34)로 분산작용되게 된다.The coupling structure of the conventional trailer arm is coupled to the rear side plate 35 of the vehicle body to the towing ball 40 to tow the trailer by the towing ball 40, the load applied to the towing ball 40 during the tow Through the fixing plate 39 on both sides of the bar 41, the rear door 35 and the rear floor panel 34 are dispersed.

그러나 이러한 종래 트레일러암의 결합구조는, 조립시 리어론지(35)의 저면쪽에서 삽입되어 리어플로어판넬의 상면에서 고정너트()에 의해 결합되도록 하기 때문에 조립작업이 용이하지 않았으며, 또한 하부로 돌출되는 리어론지에서 하부로 절곡 돌출되게 취부되는 구조로되어 차체와 지면과의 여유공간이 비교적 좁게 되기 때문에 결합작업이 어려운 문제점이 있었다.However, the assembly structure of the conventional trailer arm is not easy to assemble because it is inserted from the bottom side of the rear door 35 to be assembled by a fixing nut () on the upper surface of the rear floor panel during assembly, and also protrudes downward. Since the structure is mounted to be protruded bent downward from the rear lodge, there is a problem that the coupling work is difficult because the free space between the vehicle body and the ground is relatively narrow.

본 발명은 상기와 같은 종래의 문제점을 해소하기 위하여 안출한 것으로, 토잉볼이 결합되는 트레일러암이 평면적으로 형성되어 평면부가 보강판들에 의해 리어플로워판넬의 저면부에 결합되도록 하므로 지면과의 여유공간을 확보하고 결합작업이 용이하도록 하는 것이다.The present invention has been made in order to solve the above conventional problems, because the trailer arm to which the towing ball is coupled is formed in a flat plane so that the flat portion is coupled to the bottom part of the rear follower panel by the reinforcement plates, so that there is room with the ground. It is to make space and to facilitate the joining work.

먼저, 본 발명의 자동차도 차체의 저면을 이루는 플로어판넬의 저면 양쪽에 소정 간격을 두고 하부로 돌출되는 리어론지가 입체형상으로 결합되고, 트레일러를 견인하기 위한 트레일러암이 차체 후부쪽에 결합된다.First, the rear door projecting downwards at both sides of the floor of the floor panel forming the bottom of the vehicle body is coupled in three-dimensional shape, and the trailer arm for towing the trailer is coupled to the rear of the vehicle body.

단, 본 발명은 제3도와 제4도에 도시되는 바와 같이, 양쪽 리어론지(도시생략) 사이의 리어플로어판넬(34) 저면에 하부보강크로스멤버(16)가 취부되고, 상기 하부보강크로스멤버가 위치되는 리어플로어판넬의 상면에 상부보강크로스멤버(14)가 결합되며, 상기 상부보강크로스멤버 상부에 마운팅판넬(15)이 결합되어, 일정두께와 폭을 갖는 프레임으로 형성되고 일단부에 상향으로 만곡되게 연장되는 토잉어셈블리(11)가 결합되는 트레일러암(13)이 상기 하부보강크로스멤버와 리어플로어판넬의 저면부에 볼트들에 의해 결합됨을 그 기술적 구성상의 기본 특징으로 한다.However, in the present invention, as shown in FIG. 3 and FIG. 4, the lower reinforcement cross member 16 is attached to the bottom of the rear floor panel 34 between both rear longages (not shown). The upper reinforcement cross member 14 is coupled to the upper surface of the rear floor panel in which the upper reinforcement cross member is mounted, and the mounting panel 15 is coupled to the upper reinforcement cross member upper portion, and formed into a frame having a predetermined thickness and width and upwardly at one end. The trailer arm 13 to which the towing assembly 11, which is curvedly extended, is coupled by bolts to the bottom of the lower reinforcement cross member and the rear floor panel.

여기에서, 트레일러암(13)은 소정폭과 두께를 갖는 입체형 프레임(12)의 일단부에 절개부가 형성되어, 상기 일단 절개부에 상향으로 만곡되게 연장되는 토잉볼지주(11)가 용접에 의해 결합되며, 토잉볼지주(11)의 끝단부에 토잉볼이 결합된다.Here, the trailer arm 13 has a cutout portion formed at one end of the three-dimensional frame 12 having a predetermined width and thickness, and the towing ball column 11 extending upwardly curved to the end cutout portion is welded. Is coupled, the towing ball is coupled to the end of the towing ball holder (11).

이기서, 미설명 부호 43은 하부브라켓판넬이고, 44는 상부브라켓판넬, 45는 리어범퍼임팩트빔, 46은 스페어타이어, 47은 리어범퍼이다.Here, reference numeral 43 is a lower bracket panel, 44 is an upper bracket panel, 45 is a rear bumper impact beam, 46 is a spare tire, and 47 is a rear bumper.

이와같이 구성되는 본 발명은 자동차의 스페어타이어(46)가 격납되는 리어플로어판넬(34)의 저면에 트레일러암(13)의 프레임(12)부가 결합되고, 트레일러암(13)의 프레임(12)에 완만한 곡율을 갖고 토잉어셈블리(11)가 연결되므로, 높이차가 크지 않게 이어져 지면과의 여유공간이 확보되게 된다. 또한, 여유공간이 넓으므로 트레일러암(13)을 차체에 결합시킬 때, 그 작업이 용이하도록 하며, 차체의 높이가 비교적 낮은 형태의 차량에 있어서도 트레일러암의 설치시에 따른 제약이 줄어들게 된다.In the present invention configured as described above, the frame 12 of the trailer arm 13 is coupled to the bottom of the rear floor panel 34 in which the spare tire 46 of the vehicle is stored, and the frame 12 of the trailer arm 13 is coupled to the frame 12. Since the towing assembly 11 is connected with a gentle curvature, the difference in height is not so large that a free space with the ground is secured. In addition, when the trailer arm 13 is coupled to the vehicle body because the clearance is large, the work is facilitated, and even in a vehicle having a relatively low height, the constraints upon installing the trailer arm are reduced.

이와같이 구성되고 작동되는 본 발명은, 트레일러암이 리어플로어판넬의 저면에 결합되어, 트레일러암의 설치시 여유공간이 크게 되므로 설치작업이 용이하게 되는 효과를 갖는다.The present invention configured and operated as described above has the effect that the trailer arm is coupled to the bottom of the rear floor panel, and thus the installation space becomes easy since the free space is increased during the installation of the trailer arm.
