본 고안은 자동차에 장비되는 후부현가장치에 관한 것으로 특히 비틀림 비임에 의하여 선회주행시등에 있어서 복원성을 확보하도록한 소위 비틀림비임식의 후부현가장치에 관한 것이다.The present invention relates to a rear suspension device equipped with a vehicle, and more particularly, to a so-called torsion beam rear suspension device that ensures stability in turning driving by torsion beams.
종래에는 이와같은 자동차의 비틀림비임식 후부현가장치로서, 예를들어 미국특허 제4165099호 명세서 및 도면에 개시되어 있는 것과 같이, 차체의 전후방향으로 연설되어 전단이 차체에 회동이 자유롭게 부착되고 후단으로 뒤바퀴를 지지하는 좌우한쌍의 후단아암과 그 두후단아암사이에서 차폭방향으로 연설되고, 양단이 각각 후단아암에 연결된 비틀림비임을 갖추고 선회주행시등과 같이 좌우의 뒤바퀴가 비대칭으로 충돌, 복귀하였을 때 전술한 비틀림비임의 비틀림에 의해서 복원성을 확보하도록 한 것은 알려져 있다.Conventionally, as a torsional beam rear suspension of such a vehicle, for example, as disclosed in the specification and drawings of US Pat. No. 41,650,99, it is spoken in the front and rear directions of the vehicle body, and the front end is freely attached to the vehicle body, and the rear end is The left and right rear arms supporting the rear wheels and the two rear rear arms are spoken in the vehicle width direction, and both ends are torsion beams connected to the rear arms, and the left and right rear wheels collide and return asymmetrically, such as when turning. It is known to ensure resilience by torsion of the torsion beam described above.
그리고, 이런종류의 후부 현가장치에 있어서는 통상 비틀림 비임을 단면이형으로 형성됨과 동시에 후단아암을 각각 단면이형인 외측부재와 내측부재로 서로 대향하는 상태로 중합하여 폐단면상(閉斷面狀)으로 형성하므로서 각 구성부재의 강성강도(剛性强渡)를 높이도록 되어 있다.In this type of rear suspension, the torsion beam is usually At the same time, the rear end arm The outer member and the inner member, which are of a mold, are polymerized in a state of facing each other to form a closed cross section, thereby increasing the rigid strength of each component.
한편, 전술한 비틀림비임과 후단아암을 연결함에 있어서는 여러가지 구조가 채택되어 있으며, 그 대표적 예로서는 비틀림비임의 단부를 후단아암의 외측부재에 중합하여 용접함과 동시에 후단아암의 내측부재의 전단부를 전술한 비틀림비임에 따라서 차체안쪽으로 연장하고, 그 연장부와 비틀림비임을 용접하도록 구성한 것이 있다.On the other hand, a variety of structures are employed in connecting the torsion beam and the rear end arm, and typical examples thereof include polymerizing and welding the end portion of the torsion beam to the outer member of the rear arm and the front end of the inner member of the rear arm. The torsion beam extends into the vehicle body and is configured to weld the extension portion and the torsion beam.
이런 연결구조의 경우, 후단아암의 내측부재와 비틀림비임과의 용접장소는 어느 정도 넓은 범위에 걸쳐서 확보할 수가 있으나, 후단아암의 외측부재와 비틀림비임과의 용접장소는 그 양부재와 후단아암의 내측부재와의 접속도 서로 얽혀서 양부재의 중합부에서의 비틀림비임의 측벽단이나 외측부재의 측벽단위에는 확보할 수가 없다.In the case of such a connecting structure, the welding position between the inner end of the rear arm and the torsion beam can be secured to a certain extent, but the welding position between the outer end of the rear arm and the torsion beam can be secured between the two members and the rear arm. The connection with the inner member is also entangled with each other and cannot be secured at the side wall end of the torsion beam in the polymerization portion of both members or at the side wall unit of the outer member.
그런고로 종래 전술한 후단아암의 외측부재와 비틀림비임을 연결하는데 있어서는 양부재를 직접 용접하여 연결할뿐만 아니라, 연결부재를 개재하여 연결 보강하는 것이 병용되고 있다.Therefore, in connecting the outer member and the torsion beam of the rear end arm as described above, not only welding and connecting both members directly, but also connecting and reinforcing through the connecting member are used in combination.
또한 이와같이 연결부재에 의하여 연결 보강하는 방법은 다른곳에서도 널리 사용되고 있는 것이며, 상술한 미국특허의 경우에도 후단아암의 내측부재와 비틀림 비임을 연결하는데 채용되고 있다.In addition, the method of reinforcing the connection by the connection member is widely used elsewhere, and in the case of the above-mentioned US patent, it is employed to connect the torsion beam with the inner member of the rear arm.
그러나, 상술한 바와같이 연결부재에 의하여 연결 보강하는 방법에서는 부재끼리를 직접 용접에 의해서 연결하는 경우에 비하여 연결강도가 약하기 때문에 후단아암과 비틀림비임과의 연결부의 강도를 충분히 확보할 수 없는 결점이 있다. 또 부품의 가지수도 많아져서 부품의 관리나 조립작업등 여러가지 점에서 불편하였다.However, as described above, in the method of connecting and reinforcing by the connecting member, the connection strength is weak compared to the case where the members are directly connected by welding, so that the strength of the connecting portion between the rear arm and the torsion beam cannot be sufficiently secured. have. In addition, the number of parts also increased, which was inconvenient in various aspects such as management of parts and assembly work.
본 고안은 이런점에 비추어 그 목적하는 바는 상술한 바와같이 후단아암의 외측부재와 비틀림비임을 연결함에 있어, 양 부재를 직접 용접가능한 곳을 새로 설치하므로서 연결부재를 필요로 하지 않고서 양부재의 연결부의 강도를 효과적으로 높일 수 있도록 한 것이다.The present invention in view of this point is to connect the outer member and the torsion beam of the rear end arm as described above, by installing a new place where both members can be directly welded, without the need for connecting members It is to increase the strength of the connection effectively.
이러한 목적을 달성하기 위하여 본 고안의 해결수단은 차체의 전후방향으로 연설되고 단면이 차체 안쪽으로 향한 대략형의 후단아암과 차폭방향으로 연설되고, 전술한 후단아암에 중합하는 단면이 대략형인 비틀림 비임을 갖춘 자동차의 비틀림비임식 후부 현가장치에 있어서 후단아암의 비틀림비임과의 중합부에 구멍을 뚫고 후단아암과 비틀림비임을 각기의 측벽단에서 용접함과 동시에 후단아암의 구멍둘레를 비틀림비임의 측벽에 용접한 것이다.In order to achieve this object, the solution of the present invention is roughly addressed in the front and rear direction of the vehicle body and the cross section is directed toward the inside of the vehicle body. The end face of the mold is extended in the vehicle width direction, and the cross section polymerized to the rear end arm described above is approximately In torsion beam type rear suspension of automobile with type torsion beam, drill hole in polymerization part with torsion beam of rear arm, weld rear arm and torsion beam at the end of each side wall and twist the circumference of rear arm It is welded to the side wall of the beam.
위와같은 구성에 의해서 본 고안에서는 비틀림비임과 후단아암의 복수의 장소에서 직접 용접되어져 있으므로서 그 양부재의 연결부의 강도가 종래와 같은 연결부재를 사용치않고, 아울러 연결부재를 사용한 경우와 비교하여 가급적 높아지도록 한 것이다.According to the above configuration, the present invention is directly welded at the plural places of the torsion beam and the rear arm, and the strength of the connecting portion of both members does not use the connecting member as in the prior art, and also compared with the case of using the connecting member. As high as possible.

The inner member 5, which is shaped, was formed in a closed cross-section by polymerizing in an opposite state to each other, and at the portion in front of the connection portion with the torsion beam 3, the reinforcing member substantially flat with the outer member 4; (6) is polymerized and formed in the closed cross section.
그리고 후단아암(1)과 비틀림아암(3)과의 연결부에 있어서는 후단아암(1)의 내측부재(5)의 전단부는 비틀림비임(3)을 따라서 차체 안쪽으로 연장되어 있고, 그 연장부(5a)는 비틀림비임(3)에 덮여진 상태로 그 외주연의 대략 전둘레에 결쳐서 그 비틀림비임(3)에 용접되어서 용접부분(7)을 구성하고 있다. 또 후단아암(1)의 외측부재(4)와 비틀림비임(3)과는 비틀림비임(3)의 양측벽(3a),(3a) 외면을 외측부재(4)의 양수평측벽(4a),(4a) 내면에 당접시킨 상태로 중합시키고 있고, 그 외측부재(4)의 비틀림비임(3)과의 중합부에는 그 양수평측벽(4a),(4a)부분에 각각 구멍(8),(8)이 천설되어 있다.In the connection portion between the rear end arm 1 and the torsion arm 3, the front end of the inner member 5 of the rear end arm 1 extends inward to the vehicle body along the torsion beam 3, and the extension portion 5a thereof. ) Is covered with the torsion beams 3 and is welded to the torsion beams 3 at approximately the entire circumference of the outer circumference thereof to form the welded portion 7. The outer side member 4 and the torsion beam 3 of the rear end arm 1 have both side walls 3a and 3a of the torsion beam 3 with the horizontal side walls 4a of the outer member 4, (4a) It is polymerized in the state which abuts on the inner surface, and in the superposition | polymerization part of the outer member 4 with the torsion beam 3, the hole 8, ( 8) is insulated.
그리고 외측부재(4)의 각 수평측벽(4a) 단변(端邊)은 비틀림비임(3)의 측벽(3a)외면에 용접되어 용접부분(9)을 구성하고 있는 한편, 비틀림비임(3)의 각 측벽(3a)단변은 외측부재(4)의 수평측벽(4a)내면에 용접되어서 용접부분(10)을 구성하고 있고, 또 외측부재(4)의 각 구멍(8)둘레는 비틀림 비임(3)의 측벽(3a)에 용접되어서 용접부분(11)을 구성하고 있다.The short side of each horizontal side wall 4a of the outer member 4 is welded to the outer surface of the side wall 3a of the torsion beam 3 to form a welded portion 9, while the torsion beam 3 is The short side of each side wall 3a is welded to the inner surface of the horizontal side wall 4a of the outer member 4 to form a welded portion 10, and the periphery of each hole 8 of the outer member 4 is a torsion beam 3 The welded part 11 is welded to the side wall 3a of the ().
다음에 좌우한쌍의 후단아암(1),(1)과 비틀림비임(3)을 조립하는 경우의 작업순서에 대해서 간단히 설명한다.Next, the operation procedure in the case of assembling the left and right rear arms 1, 1 and the torsion beam 3 will be briefly described.
우선 미리 비틀림아암(1)을 그 구성부재인 외측부재(4)와 내측부재(5)에 의해서 폐단면상으로 형성해둔다.First, the torsion arm 1 is formed in the closed cross section by the outer member 4 and the inner member 5 which are its constituent members.
다음에 후단아암(1)에 대하여 비틀림비임(3)을 소정의 위치로 위치결정한후 내측부재(5)의 연장부(5a) 외주연을 비틀림비임(3)에 용접한다(용접부분(7)).Next, after positioning the torsion beam 3 to the predetermined position with respect to the rear end arm 1, the outer periphery of the extension part 5a of the inner member 5 is welded to the torsion beam 3 (welding part 7). ).
또 그 용접과 동시에 외측부재(4)와 비틀림비임(3)과의 중합부에서 외측부재(4)의 각 수평측벽(4a)단변을 비틀림비임(3)의 측벽(3a)외면에, 비틀림비임(3)의 각 측벽(3a)단변을 외측부재(4)의 수평측벽(4a)내면에 각각에 용접함(용접부분(9),(10))과 동시에 외측부재(4)의 비틀림비임(3)과의 중합부에 설치한 구멍(8),(8) 둘레는 비틀림비임(3)의 측벽(3a) 외면에 용접한다(용접부분(11)).At the same time as the welding, at the polymerization portion between the outer member 4 and the torsion beam 3, the short side of each horizontal side wall 4a of the outer member 4 is placed on the outer surface of the side wall 3a of the torsion beam 3 to the torsion beam. (3) Short edges of the side walls 3a are respectively welded to the inner surface of the horizontal side wall 4a of the outer member 4 (welding portions 9 and 10) and at the same time the torsion beam of the outer member 4 The periphery of the holes 8 and 8 provided in the polymerization section with 3) is welded to the outer surface of the side wall 3a of the torsion beam 3 (welding portion 11).
그런후에 후단아암(1)의 비틀림비임(3)과의 연결부 보다도 앞쪽에 있어서 외측부재(4)의 안쪽에 보강재(6)를 중합하여 양부재(4),(6)를 용접한다.Thereafter, the reinforcing member 6 is polymerized inside the outer member 4 in front of the connecting portion of the rear arm 1 with the torsion beam 3 to weld both members 4 and 6.
이러한 작업을 후단아암(1),(1)과 비틀림비임(3)과의 사이에서 각각 행하므로서 좌우한쌍의 후단아암(1),(1)과 비틀림비임(3)과의 조립작업이 종료한다.This operation is performed between the rear arms 1, 1 and the torsion beam 3, respectively, and the assembly work of the left and right rear arms 1, 1 and the torsion beam 3 is completed. .
이와같이 후단아암(1)의 외측부재(4)와 비틀림비임(3)과의 연결에 있어서는 후단아암(1)의 내측부재(4)와의 위치관계에서 영향되지 않고, 외측부재(4)의 수평측벽(4a)단변이나, 비틀림비임(3)의 측벽(3a) 단변과 같이 외측부재(4)의 구멍(8)둘레에서도 용접할 수가 있으므로 그 용접장소의 증가에 의해서 양부재(4),(3)의 연결강도를 가급적 높힐수가 있다.In this way, the connection between the outer member 4 of the rear arm 1 and the torsion beam 3 is not affected by the positional relationship between the inner member 4 of the rear arm 1 and the horizontal side wall of the outer member 4. (4a) Since both sides can be welded at the periphery of the hole 8 of the outer member 4, such as the short side and the short side of the side wall 3a of the torsion beam 3, both members 4 and 3 are increased by increasing the welding position. ) Can increase the connection strength as much as possible.
더우기 외측부재(4)와 비틀림비임(3)과의 연결구조는 종래와 같은 연결부재를 필요로 하지 않고, 부품의 가치수도 적게할수가 있으므로, 조립작업의 간편화나 차체의 경량화(輕量化)를 도모할수 있음과 동시에, 부품관리면에 있어서도 유리하다.Furthermore, the connection structure between the outer member 4 and the torsion beam 3 does not require the connection member as in the prior art, and the number of parts can be reduced, thereby simplifying the assembly work and reducing the weight of the vehicle body. At the same time, it is also advantageous in terms of parts management.
또한 외측부재(4)에 설치한 구멍(8)은 비틀림비임(3)과의 중합부에 위치하고 아울러 그 구멍(8)둘레가 비틀림비임(3)의 측벽(3a)에 용접되어서 비틀림비임(3)과 일체화되기 때문에 그 구멍(8)에 의해서 외측부재(4)의 강도가 저하되는 일은 없다.In addition, the hole 8 provided in the outer member 4 is located in the polymerization portion with the torsion beam 3, and the periphery of the hole 8 is welded to the side wall 3a of the torsion beam 3 so that the torsion beam 3 ), The strength of the outer member 4 is not lowered by the hole 8.
이상과 같이 본 고안에 의하면 후단아암의 비틀림비임과의 중합부에 구멍을 설치하는 것만으로서 후단아암과 비틀림 비임을 복수의 장소에서 직접 용접할수가 있으므로 종래의 연결부재를 개재해서 연결하는 경우에 비하여 양부재의 강도를 높힐수가 있음과 동시에 부품의 가지수를 적게하여 부품관리의 용이화나 조립작업의 간이화등을 도모할수가 있는 것이다.As described above, according to the present invention, it is possible to directly weld the rear arm and the torsion beam at a plurality of places by simply providing a hole in the polymerization portion with the torsion beam of the rear arm, as compared with the case of connecting through a conventional connecting member. The strength of both members can be increased, and the number of parts can be reduced, thereby facilitating parts management and simplifying assembly work.
