비틀림 강성이 향상된 ＣＴＢＡ {CTBA improving torsion stiffness}CTBA improving torsion stiffness CTBA improved torsional stiffness

본 발명은 차량의 현가장치의 한 종류인 CTBA에 관한 것으로서, 더욱 상세하게는 비틀림에 대한 강성이 증대되어 NVH 문제를 해결하고, 내구성을 향상시킨 비틀림 강성이 향상된 CTBA에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a CTBA, which is one type of suspension of a vehicle, and more particularly, to a CTBA with improved torsional stiffness which improves rigidity against torsion to solve NVH problem and improve durability.

차량 현가장치의 하나인 CTBA는 구조가 간단하여 생산성이 좋고, 경량화에 유리하여, 상대적으로 소형차의 후륜 현가장치로 많이 적용되고 있다.CTBA, which is one of the vehicle suspension systems, has a simple structure, is good in productivity, is advantageous in weight saving, and is applied to rear wheel suspensions of relatively small cars.

이러한 CTBA는 통상적으로 도 1 및 도 2에 도시된 바와 같은 구조로 이루어진다. 즉, 차량의 폭방향으로 토션빔(111) 구비되고, 상기 토션빔(111)의 양단에 각각 트레일링암(112)이 구비되며, 상기 트레일링암(112)이 휠 마운트 브라켓(113)을 통해서 후륜(RW)이 마운트되고, 상기 트레일링암(112)이 스프링(116)과 리어 쇽업저버(115)가 구비되어 차체에 연결된다.Such a CTBA typically has a structure as shown in FIGS. 1 and 2. That is, a torsion beam 111 is provided in the width direction of the vehicle, trailing rocks 112 are provided at both ends of the torsion beam 111, and the trailing rocks 112 are supported by the rear mount And the trailing rocker 112 is provided with a spring 116 and a rear shock absorber 115 to be connected to the vehicle body.

그러나, 상기와 같은 구성을 갖는 CTBA(100)는, 도 5에 도시된 바와 같이, 후륜(RW)의 휠센터에 입력되는 하중(+Fz_w)과 리어 쇽업저버(115) 및 스프링(116)으로부터 입력되는 하중(-Fz_d)(-Fz_s)의 불균형으로 비틀림을 발생한다.5, the load (+ Fz_w) input to the wheel center of the rear wheel RW and the load (+ Fz_w) input from the rear shock absorber 115 and the spring 116 (-Fz_d) (-Fz_s) is generated due to unbalance of the input load (-Fz_d) (-Fz_s).

또한, 리어 쇽업저버(115)가 트레일링암(112)과 토션빔(111)의 결합부에서 후방으로 편심되도록 상기 트레일링암(112)에 연결되어 있어서, NVH(Noise, Vibration, and Harshness) 및 내구성에서도 문제가 된다.The rear shock absorber 115 is connected to the trailing rocker 112 so as to be eccentrically rearward at a coupling portion between the trailing rocker 112 and the torsion beam 111. The rear shock absorber 115 has noise, vibration, and harshness (NVH) .

이를 해결하기 위해서, 도 3 및 도 4에 도시된 바와 같이, 토션빔(111)과 트레일링암(112)이 결합되는 부위에 보강부재(117)를 용접하여 CTBA에 가해지는 전단하중과 비틀림 하중에 대하여 강도를 보강토록 하고 있다. 그러나, 상기 보강부재(117)의 용접부위에 응력집중으로 인하여 크랙이 발생할 수 있고, 보강부재(117)를 용접에 의해 추가적으로 장착해야 하기 때문에 생산성을 저하시키는 문제점이 있다.3 and 4, a reinforcing member 117 is welded to a portion where the torsion beam 111 and the trailing rocker 112 are coupled, and a shear load and a torsional load applied to the CTBA To reinforce the strength. However, cracks may occur due to stress concentration on the welded portion of the reinforcing member 117, and the reinforcing member 117 must be additionally attached by welding, thereby lowering the productivity.

상기와 같은 CTBA의 예로서, 하기와 같은 선행기술문헌이 존재한다.As an example of such a CTBA, the following prior art documents exist.

이하 첨부된 도면을 참조로 하여 본 발명에 따른 비틀림 강성이 향상된 CTBA를 자세히 설명하기로 한다.
The CTBA with improved torsional rigidity according to the present invention will now be described in detail with reference to the accompanying drawings.

도 6 내지 도 8에 도시된 바와 같이, 본 발명에 따른 비틀림 강성이 향상된 CTBA(10)는, 토션빔(11)과 트레일링암(12)이 서로 결합되는 부분에, 리어 쇽업저버(15)의 하단이 체결되도록 한다.6 to 8, the CTBA 10 with improved torsional rigidity according to the present invention has a structure in which the torsion beam 11 and the trailing arm 12 are engaged with each other at a portion of the rear shock absorber 15 Make sure the bottom is fastened.

이를 위해서, 토션빔(11)은 상부가 개방된 형태를 갖도록 하고, 리어 쇽업저버(15)의 하단은 상기 토션빔()의 내부에 수용되는 형태로 트레일링암(12)에 연결된다.To this end, the torsion beam 11 has an open top shape and the lower end of the rear shock absorber 15 is connected to the trailing arm 12 in a manner accommodated in the torsion beam.

토션빔(11)은 단면이 오목하게 상부가 개방된 'V'자 형태로 형성되고, 양단에 각각 트레일링암(12)과 결합된다. 상기 토션빔(11)은 일반적인 CTBA에서는 단면이 하부가 개방된 '역V'자 형태로 형성되지만, 본 발명에 따른 비틀림 강성이 향상된 CTBA에서는 상부가 개방된 'V'자 형태로 형성되도록 한다.The torsion beam 11 is formed in a 'V' shape having a concave upper opening and a trailing arm 12 at both ends thereof. The torsion beam 11 is formed in an inverted V shape whose cross section is opened in a general CTBA but is formed in an open V shape in a CTBA having improved torsional rigidity according to the present invention.

특히, 상기 토션빔(11)은 리어 쇽업저버(15)가 트레일링암(12)에 연결될 때의 각도를 고려하여, 상측 후방을 향해 개방되도록 한다. 즉, 도 8에 도시된 바와 같이, 상기 토션빔(11)는 상기 리어 쇽업저버(15)가 트레일링암(12)에 연결되는 각도에 대응하도록 상측 후방을 향하도록 상부면이 개방되게 형성된다.In particular, the torsion beam 11 is opened toward the upper rear side in consideration of the angle when the rear shock absorber 15 is connected to the trailing arm 12. That is, as shown in FIG. 8, the torsion beam 11 is formed such that the upper surface thereof is opened so that the rear shock absorber 15 faces the upper rear so as to correspond to the angle connected to the trailing arm 12.

리어 쇽업저버(15)는 상기 트레일링암(12)에 하단이 연결될 때, 샤프트(15a)와 고무재질의 부시(15b)를 이용하여 연결된다.The rear shock absorber 15 is connected to the shaft 15a using a bush 15b made of rubber when the lower end of the trailing arm 12 is connected to the trailing arm 12. [

즉, 상기 샤프트(15a)가 트레일링암(12)을 관통하도록 구비되고, 상기 샤프트(15a)에 상기 리어 쇽업저버(15)의 하단이 핀조인트 방식으로 연결된다.That is, the shaft 15a passes through the trailing arm 12 and the lower end of the rear shock absorber 15 is connected to the shaft 15a by a pin joint method.

이때, 상기 샤프트(15a)의 외측으로 고무재질의 부시(15b)가 개재된 상태에서, 상기 샤프트(15a)에 리어 쇽업저버(15)의 하단이 연결됨으로써, 상기 부시(15b)에서 추가적으로 완충되도록 함으로써, 노면으로부터 전달되는 진동을 흡수할 수 있다.
At this time, the lower end of the rear shock absorber 15 is connected to the shaft 15a in a state where a bush 15b made of rubber is disposed outside the shaft 15a so that the shock absorber 15 can be additionally buffered in the bush 15b. The vibration transmitted from the road surface can be absorbed.

이상에서 살펴본 바와 같이, 토션빔(11)의 단면을 'V'자로 형성하되, 개방된 개방된 부분이 상측 후방을 향하도록 하고, 토션빔(11)과 트레일링암(12)이 접합되는 부분에 리어 쇽업저버(15)의 하단이 핀조인트로 연결되되, 리어 쇽업저버(15)와 트레일링암(12)의 연결부위가 상기 토션빔(11)의 내부에 위치하도록 하면, CTBA의 비틀림 강성이 증대되는 효과가 있다.As described above, the torsion beam 11 is formed in the shape of a V-shaped cross-section, and the open portion of the torsion beam 11 is directed to the upper rear side, and the torsion beam 11 and the trailing arm 12 are joined When the lower end of the rear shock absorber 15 is connected by a pin joint and the connecting portion between the rear shock absorber 15 and the trailing arm 12 is positioned inside the torsion beam 11, the torsional rigidity of the CTBA is increased .

즉, 트레일링암(12)의 측면에서 서로 인접한 부위, 특히 토션빔(11)의 단부가 용접된 부분의 내측에 트레일링암(12)의 하단이 연결됨으로써, 도 9에 도시된 바와 같이, 휠 마운트 브라켓(13)에 장착된 후륜(RW)의 휠 센터에 입력되는 하중(+Fz_w)과 트레일링암(12)에 하단이 연결된 리어 쇽업저버(15)와 스프링시트(14)에 안착된 스프링(16)에 가해지는 하중(-Fz_d)(-Fz_s)이 종래기술에 비하여 균형되게 작용한다.9, the lower end of the trailing arm 12 is connected to the inner side of a portion adjacent to each other on the side surface of the trailing arm 12, in particular, a welded portion of the end portion of the torsion beam 11. As a result, A rear shock absorber 15 having a load (+ Fz_w) input to the wheel center of the rear wheel RW mounted on the bracket 13 and a lower end connected to the trailing arm 12 and a spring 16 (-Fz_d) (-Fz_s) acting on the load-side load balancer in comparison with the prior art.

따라서, 트레일링암(12)에 가해지는 하중이 종래 기술에 비하여 상기 트레일링암(12)의 일측에 토션빔(11)과 리어 쇽업저버(15)가 연결되므로, 외부로 가해진 진동에 대하여 비틀림 변형을 최소화할 수 있다. Therefore, the torsion beam 11 and the rear shock absorber 15 are connected to one side of the trailing arm 12 in comparison with the prior art in terms of the load applied to the trailing arm 12. Therefore, Can be minimized.
