Description

자동차의 토션빔액슬{torsion beam axle for a car} Torsion beam axle for a car

본 발명은 자동차의 토션빔액슬에 관한 것으로, 특히 보강부재의 적용을 폐지할 수 있게 됨으로써 부품수 절감에 따라 공수 절감 및 중량 감소를 이룰 수 있도록 된 자동차의 토션빔액슬에 관한 것이다.The present invention relates to a torsion beam axle of an automobile, and more particularly, to a torsion beam axle of an automobile capable of abolishing the application of the reinforcing member, thereby achieving a reduction in labor and weight according to the number of parts.

상기 토션빔액슬은 일반 독립현가방식의 현가장치에 비하여 구조가 단순하고 부품수가 적기 때문에 주로 중/소형 차량의 뒷현가장치로 많이 사용되고 있다.The torsion beam axle is mainly used as a rear suspension of a medium / small vehicle, because the structure is simple and the number of parts is small, compared to a general independent suspension system.

상기 토션빔액슬은 U 또는 V 자 단면 형상을 갖는 토션빔과, 상기 토션빔과 휠(타이어)을 연결하는 트레일링암으로 이루어지며, 상기 트레일링암에는 주행 진동 흡수를 위한 스프링이 설치되는 스프링시트가 구비된다.The torsion beam axle is composed of a torsion beam having a U- or V-shaped cross section, and a trailing arm connecting the torsion beam and a wheel (tire), and the trailing arm has a spring seat for installing a spring for absorbing driving vibration. It is provided.

또한, 상기 토션빔의 비틀림강성을 보완하기 위하여 대체로 삼각형상의 보강부재를 토션빔과 트레일링암의 연결부위에 설치하고 있다.Further, in order to compensate for the torsional rigidity of the torsion beam, a triangular reinforcement member is generally installed at the connection portion between the torsion beam and the trailing arm.

상기와 같이 기본 구성품(토션빔, 트레일링암, 스프링시트) 이외에 강성 보강을 위한 보강부재를 추가로 적용함으로써 부품수가 증가되고, 이에 제조 공정수가 증가됨으로써 제조원가가 증가되는 문제점이 있었다.As described above, the number of parts is increased by additionally applying a reinforcing member for rigid reinforcement in addition to the basic components (torsion beam, trailing arm, and spring sheet), thereby increasing the manufacturing cost by increasing the number of manufacturing processes.

또한, 상기와 같이 부품수가 증가됨으로써 중량이 증가하여 연비가 악화되는 문제점이 있었다.In addition, as the number of parts increases as described above, there is a problem in that the fuel economy is deteriorated due to an increase in weight.

그러나, 상기 보강부재를 설치하지 않을 경우 토션빔의 비틀림강성을 충분히 만족시킬 수 없어서 현가장치로서 롤 억제력을 충분히 발휘할 수 없게 되는 또 다른 문제점이 발생하므로 단순히 보강부재를 삭제하는 것으로 상기 문제점을 해결하는 것은 적절하지 못하였다.However, when the reinforcing member is not installed, the torsional rigidity of the torsion beam cannot be sufficiently satisfied, so another problem arises that the roll restraining force cannot be sufficiently exhibited as a suspension device. It was not appropriate.

이에 본 발명은 상기와 같은 사항을 감안하여 발명된 것으로, 토션빔의 비틀림강성을 충분히 확보하면서도 보강부재의 적용을 폐지할 수 있게 됨에 따라 부품수 감소에 따른 공수 감소, 비용 절감, 중량 감소, 연비 향상 등의 효과를 유발할 수 있도록 된 자동차의 토션빔액슬을 제공함에 그 목적이 있다.Accordingly, the present invention has been invented in view of the above matters, and thus it is possible to abolish the application of the reinforcing member while sufficiently securing the torsional rigidity of the torsion beam, thereby reducing the number of parts due to the reduction in the number of parts, reducing the cost, weight, and fuel economy. It is an object of the present invention to provide a torsion beam axle of a vehicle that can cause an effect such as improvement.

이상 설명한 바와 같은 본 발명에 따르면,According to the present invention as described above,

성형성과 강성이 우수한 FB강종의 고장력강판으로 스프링시트를 제작하고, 상기 스프링시트가 토션빔과 트레일링암을 연결함으로써 종래의 보강부재의 적용을 폐지할 수 있게 되었다.The spring sheet is made of a high-tensile steel sheet of FB steel, which is excellent in formability and rigidity, and the spring sheet connects the torsion beam and the trailing arm, thereby eliminating the application of the conventional reinforcing member.

따라서, 부품수가 감소되어, 공수가 감소되고 제조가 용이하며 제조원가가 절감되는 효과가 있다.Therefore, the number of parts is reduced, the man-hours are reduced, manufacturing is easy and the manufacturing cost is reduced.

또한, 중량이 감소되어 차량의 연비가 향상되는 효과가 있다.In addition, the weight is reduced, thereby improving the fuel economy of the vehicle.

이하, 본 발명을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

도 1은 본 발명에 따른 토션빔액슬의 평면도이다.1 is a plan view of a torsion beam axle according to the present invention.

도시된 바와 같이, 본 발명에 따른 토션빔액슬은 토션빔(10)과, 토션빔(10)의 단부에 연결된 트레일링암(20)과, 상기 토션빔(10)과 트레일링암(20)을 연결하는 스프링시트(30)로 이루어진다.As shown, the torsion beam axle according to the present invention connects the torsion beam 10, the trailing arm 20 connected to the end of the torsion beam 10, and the torsion beam 10 and the trailing arm 20. It is made of a spring sheet (30).

상기 토션빔(10)은 차량의 횡방향을 가로질러 설치되며, 판재의 전후방향 단부가 중앙부를 중심으로 하방으로 구부려진 역U자형 또는 역V자형 단면을 가지도록 성형된다.The torsion beam 10 is installed across the transverse direction of the vehicle, and is formed to have an inverted U-shaped or inverted V-shaped cross section in which the front and rear ends of the plate are bent downward about the center.

상기 트레일링암(20)은 상기 토션빔(10)에 연결된 상태에서 차량의 전후방향으로 설치되어 앞쪽 단부는 차체 프레임에 연결되고, 뒤쪽 단부에는 휠(타이어)이 장착된다.The trailing arm 20 is installed in the front-rear direction of the vehicle in a state connected to the torsion beam 10, the front end is connected to the vehicle body frame, the wheel (tire) is mounted on the rear end.

따라서, 상기 트랜스액슬을 통해 양쪽 휠의 거동이 상호 제한됨으로써 롤링 억제를 통해 선회시 차량 자세를 안정화 시킬 수 있도록 되어 있다.Therefore, the behavior of both wheels is mutually restricted through the transaxle, so that the vehicle attitude can be stabilized during turning by suppressing rolling.

한편, 상기 스프링시트(30)는 주행 중 발생하는 진동을 감쇠시키기 위하여 구비되는 스프링의 하단을 지지한다.On the other hand, the spring seat 30 supports the lower end of the spring provided to damp the vibration generated during the driving.

상기 스프링시트(30)는 대략 평행사변형 형상으로 형성되되, 상기 스프링을 안정적으로 지지하기 위해 원형으로 오목한 스프링안착부(31)가 형성된다.The spring sheet 30 is formed in a substantially parallelogram shape, and the spring seating portion 31 is concave in a circular shape to stably support the spring.

상기 스프링안착부(31)는 중심에 형성된 원형공을 중심으로 보스가 돌출 형성되어 있어, 그 보스의 외주에 스프링을 외삽할 수 있도록 되어 있다.The spring seating portion 31 has a boss protruding from the center of the circular hole formed in the center, it is possible to extrapolate the spring to the outer periphery of the boss.

또한, 상기 스프링안착부(31)의 횡방향측 단부(차체 외측)에는 트레일링암(20)에 용접하기 위한 트레일링암측 마운팅브라켓(32)이 형성되고, 종방향측 단부(차체 전방측)에는 상기 토션빔(10)에 용접하기 위한 토션빔측 마운팅브라켓(33)이 형성된다.In addition, a trailing arm side mounting bracket 32 for welding to the trailing arm 20 is formed at the transverse side end portion (outside of the vehicle body) of the spring seat 31, and at the longitudinal end side (body front side). A torsion beam side mounting bracket 33 for welding to the torsion beam 10 is formed.

따라서, 상기 트레일링암측 마운팅브라켓(32)과 토션빔측 마운팅브라켓(33)이 각각 트레일링암(20)과 토션빔(10)에 용접됨으로써 상기 스프링시트(30)가 토션빔(10)과 트레일링암(20)을 직접 연결하게 되며, 이로써 별도의 보강부재 없이도 토션빔(10)의 비틀림강성을 보강할 수 있게 된다.Therefore, the trailing arm side mounting bracket 32 and the torsion beam side mounting bracket 33 are welded to the trailing arm 20 and the torsion beam 10, respectively, so that the spring sheet 30 is the torsion beam 10 and the trailing arm. 20 is directly connected, thereby enabling torsional rigidity of the torsion beam 10 without a separate reinforcing member.

그러나, 상기와 같은 스프링시트(30)를 단순히 종래의 스프링시트 또는 보강 부재의 재질과 같은 재질로 제작할 경우, 보강부재에 해당되는 면적만큼 스프링시트를 확장 성형한 것에 지나지 않으므로 부품수 감소에 의한 중량감소 효과는 발생하지 않는다.However, when the spring sheet 30 as described above is simply made of the same material as that of the conventional spring sheet or reinforcing member, it is only the expansion of the spring sheet by the area corresponding to the reinforcing member, so that the weight due to the reduced number of parts The reduction effect does not occur.

또한, 상기 스프링안착부(31)는 스프링의 안정적인 지지(설치 위치의 이탈 방지)와 스프링의 길이 수용(레이아웃 상의 제한조건)을 위하여 토션빔(10)이나 트레일링암(20)에 연결되는 상기 마운팅브라켓(33,32)들이 형성된 평면에 비하여 보다 낮은 높이로 깊게 형성되는 경우가 많은데, 그 성형 깊이가 경우에 따라서는 50 ~ 60 mm에 이르는 경우도 있다.In addition, the spring mounting portion 31 is the mounting connected to the torsion beam 10 or the trailing arm 20 for stable support of the spring (prevention of separation of the installation position) and acceptance of the length of the spring (constraints on the layout). The brackets 33 and 32 are often formed deeper at a lower height than the plane on which the brackets 33 and 32 are formed, and the molding depth thereof may reach 50 to 60 mm in some cases.

따라서, 일반 고장력강판은 그 성형성이 부족하여 상기와 같이 깊은 깊이의 스프링안착부(31)를 갖는 스프링시트(30)를 제조하는 것이 곤란하다.Therefore, the general high tensile strength steel sheet lacks the formability, and it is difficult to manufacture the spring sheet 30 having the spring seat portion 31 having a deep depth as described above.

따라서, 상기 스프링시트(30)는 FB강종의 고장력강판으로 제작된다.Therefore, the spring sheet 30 is made of high-tensile steel sheet of FB steel.

상기 FB강종은 페라이트(Ferrite)와 베이나이트(Bainite)로 구성된 2상 조직강으로서 연신율, 신장플랜지성, 구멍확장성이 우수하여 성형성이 매우 좋다.The FB steel is a two-phase structured steel composed of ferrite and bainite, and has excellent elongation, elongation flangeability, and hole expandability.

또한 고장력강판은 같은 강도를 가질 때 제품의 두께가 감소되어 중량이 감소되는 장점을 가진다.In addition, high strength steel sheet has the advantage that the weight of the product is reduced when the same strength is reduced.

따라서, 상기 스프링시트(30)를 FB강종의 고장력강판으로 제작하면, 종래의 경우보다 스프링시트(30) 자체의 면적이 확장되었다 하더라도 두께의 감소로 인해 종래의 스프링시트와 보강부재의 중량합보다 작은 중량을 갖게 되므로 부품수 감소와 중량감소 효과를 모두 가질 수 있게 된다.Therefore, when the spring sheet 30 is made of a high-tensile steel sheet of FB steel, even if the area of the spring sheet 30 itself is expanded than the conventional case, due to the reduction in thickness than the sum of the weight of the conventional spring sheet and the reinforcing member Since it has a small weight, it is possible to have both parts reduction and weight reduction effects.

또한, 상기 FB강종의 고장력강판은 그 성형성이 우수하므로 상기와 같이 깊 은 깊이의 스프링안작부(31)를 갖는 스프링시트(30)를 성형하는데 문제가 없다.In addition, the high-tensile steel sheet of the FB steel is excellent in formability, there is no problem in forming the spring sheet 30 having the spring stabilizer 31 of deep depth as described above.

상기와 같이 부품수가 감소되면 종래의 보강부재를 제조하고, 취급 관리하며, 보강부재를 토션빔과 트레일링암 사이에 장착하는 모든 공정이 필요 없게 되므로 공수가 크게 감소하여 제조가 용이하고 원가가 절감되는 효과가 발생한다.When the number of parts is reduced as described above, manufacturing and handling of conventional reinforcing members are eliminated, and all the processes of mounting the reinforcing members between the torsion beam and the trailing arm are unnecessary, thus greatly reducing the labor and manufacturing cost and reducing the cost. Effect occurs.

또한, 중량이 감소되므로 차량의 연비가 향상되는 효과도 있다.In addition, since the weight is reduced, there is an effect that the fuel economy of the vehicle is improved.

도 2는 도 1의 변형 실시예로서, 스프링시트(30)에 있어서, 상기 트레일링암측 마운팅브라켓(32)과 상기 토션빔측 마운팅브라켓(33)의 사이 중간 부분에 또 다른 트레일링암측 마운팅브라켓(34)이 추가 형성되고, 상기 또 다른 트레일링암측 마운팅브라켓(34)은 토션빔(20)의 대응 부위(맞대어지는 부위)에 용접된다.2 is a modified embodiment of Figure 1, in the spring seat 30, another trailing arm side mounting bracket (in the middle portion between the trailing arm side mounting bracket 32 and the torsion beam side mounting bracket 33 ( 34 is further formed, and the further trailing arm side mounting bracket 34 is welded to a corresponding portion (buttted portion) of the torsion beam 20.

따라서, 상기 스프링시트(30) 자체의 장착강도가 보다 향상되어 보다 견고하고 안정적으로 스프링을 지지할 수 있으며, 상기 토션빔(20)과 트레일링암(20)을 보다 강력하게 연결해줌으로써 토션빔(10)의 비틀림강성을 더욱 보강할 수 있게 된다.Therefore, the mounting strength of the spring seat 30 itself is further improved to support the spring more firmly and stably, and by connecting the torsion beam 20 and the trailing arm 20 more strongly, the torsion beam 10 The torsional rigidity of) can be further reinforced.

이 경우, 상기 스프링시트(30)의 두께를 더 얇게 할 수 있으므로 중량감소 효과는 배가된다.In this case, since the thickness of the spring sheet 30 can be made thinner, the weight reduction effect is doubled.

그러나, 상기와 같이 스프링시트(30)의 두께를 얇게 하는 것은 강성의 저하를 초래하여 토션빔의 비틀림강성을 감소시키므로 상기 스프링시트(30)의 두께는 토션빔의 비틀림강성과 트랜스액슬의 중량을 모두 감안하여 적정 선에서 결정되어야 할 것이다.However, thinning the thickness of the spring sheet 30 as described above results in a decrease in rigidity and reduces the torsional rigidity of the torsion beam, so that the thickness of the spring sheet 30 is the torsional rigidity of the torsion beam and the weight of the transaxle. All of them will have to be decided on the right line.
