Description

ＣＴＢＡ 현가장치에서 토션빔의 용접 구조{Structure of welding in CTBA suspension}Structure of welding in CTBA suspension

본 발명은 CTBA 현가장치에서 토션빔을 트레일링암에 용접하는 용접구조에 관한 것으로서, 더욱 상세하게는 토션빔을 트레일링암에 용접할 때, 트레일링암과 토션빔을 맞대기 용접할 수 있도록 하는 CTBA 현가장치에서 토션빔의 용접구조에 관한 것이다.The present invention relates to a welding structure for welding a torsion beam to a trailing arm in a CTBA suspension device, and more particularly, a CTBA suspension device for welding a torsion beam to a torsion beam when welding a torsion beam to a trailing arm. Relates to a welding structure of a torsion beam.

자동차 현가장치의 하나인 CTBA 현가장치는 구조가 간단하고 적은 생산비용으로 인하여, 소형승용차를 위주로 적용되고 있다.CTBA suspension, which is one of automobile suspension systems, is applied mainly to small passenger cars due to its simple structure and low production cost.

이러한, CTBA 현가장치의 대략적인 구조를 첨부된 도 1을 통해 살펴보면, 토션빔(101)과, 상기 토션빔(101)의 양측단에 각각 구비되는 트레일링암(102)과, 상기 트레일링암(102)의 구비되어 스프링, 댐퍼 및 휠이 체결되도록 하는 스프링시트(103), 댐퍼브라켓(104) 및 휠마운트브라켓(105)을 구비한다.The structure of the CTBA suspension device is described with reference to FIG. 1 attached to the torsion beam 101, the trailing arm 102 provided at both ends of the torsion beam 101, and the trailing arm 102. ) Is provided with a spring seat 103, a damper bracket 104 and a wheel mount bracket 105 to be fastened to the spring, the damper and the wheel.

이러한 CTBA 현가장치(100)를 제조하는 과정 중에는 토션빔(101)과 트레일링암(102)을 용접하는 과정에 수반된다.In the process of manufacturing the CTBA suspension device 100 is involved in the process of welding the torsion beam 101 and the trailing arm (102).

즉, 도 2에 도시된 바와 같이, 토션빔(101)의 선단을 내측부재(102a)와 외측부재(102b)가로 용접되어 이루어진 트레일링암(102)의 측면에 접하도록 하고, 통상 T형 필렛 용접으로 토션빔(101)과 트레일링암(102)이 일체가 되도록 한다.That is, as shown in FIG. 2, the tip of the torsion beam 101 is brought into contact with the side surface of the trailing arm 102 formed by welding the inner member 102a and the outer member 102b to each other. Thus, the torsion beam 101 and the trailing arm 102 are integrated.

그러나, 상기와 같은 방법으로 용접을 하면, 토션빔(101)의 선단과 트레일링암(102)의 측면의 곡면형상이 서로 일치하지 않기 때문에 용접부분의 품질이 떨어지게 되고, 극단적으로는 도 3에 도시된 바와 같이, 토션빔(101)과 트레일링암(102) 사이에 용접되지 않은 공간(C)생길 수도 있다. 토션빔(101)과 트레일링암(102)의 서로 일치하도록 맞닿은 상태에서 용접되어야 하는데, 서로 불일치 한 상태에서 용접을 하게 되어, 토션빔(101)과 트레일링암(102)이 서로 맞닿는 부분의 용접품질이 나빠지게 되고, 이는 곧 차량의 품질과 관련된다.However, when welding is performed in the above manner, the quality of the welded portion is degraded because the curved shape of the tip of the torsion beam 101 and the side of the trailing arm 102 does not coincide with each other, and is extremely shown in FIG. As shown, an unwelded space C may be created between the torsion beam 101 and the trailing arm 102. The torsion beam 101 and the trailing arm 102 should be welded in contact with each other to match each other, but the welding quality is inconsistent with each other, so that the welding quality of the portion where the torsion beam 101 and the trailing arm 102 abut each other. This becomes worse, which is related to the quality of the vehicle.

또한, 용접작업을 하는 동안에도 서로 곡면형상이 일치하지 않아서, 용접하는 동안 토션빔(101)과 트레일링암(102)을 지지하기가 용이하지 않은 문제점이 있다.In addition, there is a problem that the curved shapes do not coincide with each other during the welding operation, and thus it is not easy to support the torsion beam 101 and the trailing arm 102 during welding.

한편, CTBA 현가장치에서 토션빔과 트레일링암의 용접구조를 개선하기 위한 예로의 하나로 하기의 선행기술문헌이 존재한다.On the other hand, as an example for improving the welding structure of the torsion beam and the trailing arm in the CTBA suspension device, the following prior art document exists.

한편, 상기 트레일링암의 내측부재의 일측에는 내측부재를 관통하는 관통공이 형성되고, 상기 관통공의 외측둘레에는 상기 연결파이프의 둘레를 감싸도록 버가 형성되는 것을 특징으로 한다.Meanwhile, a through hole penetrating the inner member is formed at one side of the inner member of the trailing arm, and a burr is formed at the outer circumference of the through hole to surround the connection pipe.

Hereinafter, the welding structure of the torsion beam in the CTBA suspension device according to the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 따른 CTBA 현가장치에서 토션빔의 용접 구조는, 차량의 후방에 차량의 폭방향으로 구비되는 토션빔(11)과, 상기 토션빔(11)의 선단이 측면에 용접되는 트레일링암(12)과, 일단은 상기 토션빔(11)의 선단에 삽입되고, 타단은 상기 트레일링암(12)을 관통하며, 상기 토션빔(11)과 트레일링암(12)을 맞대기 용접에 의해 일체가 되도록 하는 연결파이프(13)를 구비한다.
In the CTBA suspension system according to the present invention, the torsion beam welding structure includes a torsion beam 11 provided in the width direction of the vehicle at the rear of the vehicle, and a trailing arm 12 in which the tip of the torsion beam 11 is welded to the side surface. ), And one end is inserted into the tip of the torsion beam 11, and the other end penetrates the trailing arm 12, and the torsion beam 11 and the trailing arm 12 are integrated by butt welding. A connecting pipe 13 is provided.

토션빔(11)은 차량의 폭방향으로 구비되고, 내부는 중공형 구조로 형성된다.The torsion beam 11 is provided in the width direction of the vehicle, and the inside of the torsion beam 11 is formed in a hollow structure.

트레일링암(12)은 상기 토션빔(11)의 양단에 각각 구비된다. 상기 트레일링암(12)은 차량의 내측을 향하도록 배치되는 내측부재(12a)와 외측을 향하도록 배치되는 외측부재(12b)로 이루어지고, 상기 내측부재(12a)와 외측부재(12b)는 용접을 통하여 일체가 된다.The trailing arms 12 are provided at both ends of the torsion beam 11, respectively. The trailing arm 12 is composed of an inner member 12a disposed to face the inside of the vehicle and an outer member 12b disposed to face the outside, and the inner member 12a and the outer member 12b are welded. Integral through.

상기 토션빔(11)과 트레일링암(12)을 용접을 통하여 일체가 되도록 하는 바, 용접구조에 본 발명의 특징이 있다.The torsion beam 11 and the trailing arm 12 are integrally formed by welding, which is a feature of the present invention.

즉, 토션빔(11)와 트레일링암(12)을 용접함에 있어서, 토션빔(11)과 트레일링암(12) 사이에 연결파이프(13)를 개재시키고, 상기 토션빔(11)과 트레일링암(12)을 상기 연결파이프(13)와 용접되도록 함으로써, 상기 토션빔(11)과 트레일링암(12)의 용접구조를 개선시킨다.That is, in welding the torsion beam 11 and the trailing arm 12, the connecting pipe 13 is interposed between the torsion beam 11 and the trailing arm 12, and the torsion beam 11 and the trailing arm ( By welding 12 to the connection pipe 13, the welding structure of the torsion beam 11 and the trailing arm 12 is improved.

도 4 및 도 5에 도시된 바와 같이, 상기 연결파이프(13)를 토션빔(11)의 단부에 삽입되도록하고, 상기 토션빔(11)과 연결파이프(13)를 용접한다. 상기 연결파이프(13)의 외측면은 상기 토션빔(11)의 내측면에 대응하도록 형성되어, 상기 연결파이프(13)의 일측을 상기 토션빔(11)의 단부에 삽입시킬 수 있다. 상기 연결파이프(13)의 일측이 상기 토션빔(11)의 선단 내부에 삽입되면, 용접으로 상기 연결파이프(13)를 토션빔(11)의 단부에 고정시킨다.4 and 5, the connection pipe 13 is inserted into the end of the torsion beam 11, and the torsion beam 11 and the connection pipe 13 are welded. The outer surface of the connection pipe 13 may be formed to correspond to the inner surface of the torsion beam 11, so that one side of the connection pipe 13 may be inserted into an end of the torsion beam 11. When one side of the connection pipe 13 is inserted into the tip of the torsion beam 11, the connection pipe 13 is fixed to the end of the torsion beam 11 by welding.

이때, 상기 연결파이프(13)를 토션빔(11)의 단부에 용접시키는 방법으로는, 맞대기 용접을 이용하도록 한다. 맞대기 용접은 연결파이프(13)와 토션빔(11)이 연결파이프(13)가 삽입된 만큼 서로 중첩되도록 한 후, 용접하는 것이므로, 용접부위에서 공간이 생기는 것과 같은 용접부위의 용접불량을 방지한다.At this time, butt welding is used as a method of welding the connecting pipe 13 to the end of the torsion beam 11. Butt welding is to weld the connecting pipe 13 and the torsion beam 11 so as to overlap each other as long as the connecting pipe 13 is inserted, thereby preventing a welding failure of the welding site such as a space in the welding site.

또한, 상기 연결파이프(13)의 두께는 상기 토션빔(11)의 두께보다 두껍게 형성되도록 한다. 예컨대, 금속판재를 가공하여 토션빔(11)과 연결파이프(13)로 제조한다면, 연결파이프(13)를 제작하는 곰속판재의 두께가 토션빔(11)을 제작하는 금속판재의 두께보다 두껍게하여 연결파이프(13)의 두께가 두껍도록 한다.In addition, the connection pipe 13 is formed to be thicker than the thickness of the torsion beam (11). For example, if the metal plate is processed to manufacture the torsion beam 11 and the connecting pipe 13, the thickness of the back plate material for producing the connecting pipe 13 is thicker than the thickness of the metal plate for producing the torsion beam 11; The thickness of the connecting pipe 13 is made thick.

한편, 상기 연결파이프(13)의 타측은 상기 트레일링암(12)의 내측부재(12a)에 삽입된 후 용접된다. 상기 연결파이프(13)와 트레일링암(12)의 용접은 상기 연결파이프(13)와 토션빔(11)의 용접과 같이, 상기 트레일링암(12)의 내부로 연결파이프(13)가 삽입되고, 상기 트레일링암(12)과 연결파이프(13)를 용접한다.On the other hand, the other side of the connecting pipe 13 is welded after being inserted into the inner member 12a of the trailing arm 12. In the welding of the connecting pipe 13 and the trailing arm 12, the welding pipe 13 is inserted into the trailing arm 12, such as the welding of the connecting pipe 13 and the torsion beam 11. The trailing arm 12 and the connecting pipe 13 are welded.

이를 위해, 상기 트레일링암(12)의 내측부재(12a)에는 내측부재(12a)를 관통하도록 관통공을 형성하고 상기 관통공의 둘레을 따라 버링(burring)가공을 통하여 버(burr, 12ba)를 형성하고, 상기 버(12ab)의 내부로 연결파이프(13)의 타측에 삽입되도록 하여, 버(12ab)가 연결파이프(13)의 외측을 감싸는 형태가 되도록 한다.To this end, a through hole is formed in the inner member 12a of the trailing arm 12 to penetrate the inner member 12a, and a burr 12ba is formed through a burring process along the circumference of the through hole. Then, the burr 12ab is inserted into the other side of the connection pipe 13 into the burr 12ab so as to form a shape surrounding the outside of the connection pipe 13.

상기와 같이, 트레일링암(12)의 내측부재(12a)에 형성된 버(12ab)에 연결파이프(13)가 삽입되면, 연결파이프(13)와 버(12ab)를 마찬가지로 맞대기용접으로 용접하여, 트레일링암(12)과 연결파이프(13)가 일체가 되도록 한다.As described above, when the connecting pipe 13 is inserted into the burr 12ab formed on the inner member 12a of the trailing arm 12, the connecting pipe 13 and the burr 12ab are similarly welded by butt welding, and the trail The ring arm 12 and the connection pipe 13 are integrated.

따라서, 연결파이프(13)의 양측은 각각 토션빔(11)의 선단과 트레일링암(12) 내측부재(12a)의 버(12ab)에 각각 맞대기 용접되어 있으므로, 토션빔(11), 트레일링암(12) 및 연결파이프(13)는 일체가 된다.Therefore, since both sides of the connecting pipe 13 are butt welded to the front end of the torsion beam 11 and the burr 12ab of the inner member 12a of the trailing arm 12, respectively, the torsion beam 11 and the trailing arm ( 12 and the connecting pipe 13 are integrated.

이와 같이, 토션빔(11)과 트레일링암(12)을 연결파이프(13)를 매개로 하여 용접함으로써, 종래기술에서 발생했던 토션빔(11)와 트레일링암(12)의 용접불량으로 인하여 발생하는 여러 문제점을 해결할 수 있다.As such, by welding the torsion beam 11 and the trailing arm 12 through the connecting pipe 13, the torsion beam 11 and the trailing arm 12 may be generated due to a poor welding of the torsion beam 11 and the trailing arm 12. Several problems can be solved.
