Abstract

PURPOSE: A rear wheel carrier is provided to prevent a cracking situation by dispersing a shaft load along a rounded part which is the end of the rear wheel carrier of a torsion beam axle. CONSTITUTION: A trailing arm(110) is connected to a torsion beam(100) and a spring sheet(112) is installed inside the trailing arm. A rear wheel carrier is installed outside the trailing arm. The rear wheel carrier forms spindles(122) in both sides. The end of the rear wheel carrier has large loads from a rear wheel and especially a shaft load occupies large portion of the loads. Then the trailing arm fills the role of relieving the shaft load and finally cracks caused by concentrated stress. Thus, the end of the real wheel carrier is rounded by a stress dispersing device(130).

자동차의 리어 휠 케리어장치Rear wheel carrier

본 발명은 자동차의 리어 휠 케리어장치에 관한 것으로, 더욱 상세하게는 토션 비임 액슬(Torsion Beam Axle)의 리어 휠 케리어가 축하중을 받을 때에 집중되는 응력을 분산시켜 크랙의 발생가능성을 없애는 자동차의 리어 휠 케리어장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear wheel carrier device for a vehicle. More particularly, the rear wheel carrier of a torsion beam axle disperses concentrated stress when the rear wheel carrier receives a celebration and eliminates the possibility of cracks It relates to a wheel carrier device.

일반적으로, 자동차의 프레임은 많은 응력에도 견딜 수 있도록 설계되어 있고 또 외부에서 갑작스레 전해지는 예기치 못한 충격에도 이겨낼 수 있도록 되어 있다. 그러나, 상기한 강도 및 능력을 갖고 있는 프레임이라도 작은 응력이라도 어느 한부분에 집중된다면 그 프레임은 견딜 수 없게 되어 갑작스러운 사고를 맞게 된다.In general, the frame of a car is designed to withstand a lot of stress and to withstand unexpected shocks from outside. However, even if the frame having the above-mentioned strength and capability is concentrated in any part of the small stress, the frame cannot tolerate and a sudden accident occurs.

도1과 도2는 상기한 내용이 해당되는 부분을 도시한 것으로, 도1은 종래의 기술에 따른 자동차의 리어 휠 케리어장치를 도시한 전체사시도이고, 도2는 도1의 평면도이다.1 and 2 illustrate a portion to which the above description applies, and FIG. 1 is an overall perspective view showing a rear wheel carrier device of a vehicle according to the prior art, and FIG. 2 is a plan view of FIG.

전륜차량의 리어 휠은 엔진의 구동력을 받지 않으므로 구동축으로부터 연결되지 않고, 토션 비임(12)로 연결되는 좌우측 트레일링 암(Trailing Arm,10)에 형성된 리어휠 케리어(14)의 스핀들(16)에 장착된다.Since the rear wheels of the front wheel vehicle are not driven by the engine, they are not connected to the drive shaft, but are connected to the spindle 16 of the rear wheel carrier 14 formed on the left and right trailing arms 10 connected to the torsion beam 12. Is mounted.

그리고, 상기한 리어휠 케리어(14)의 안쪽으로 차량의 하중 및 노면으로부터의 충격을 완충하기위하여 스프링이 장착되는 스프링시트(18)가 장착되어 있다.Then, a spring seat 18 is mounted to the inside of the rear wheel carrier 14 to mount a spring to cushion the load of the vehicle and the impact from the road surface.

상기 리어휠은 자량의 무게를 지지하면서 온갖 환경을 갖는 노면상을 굴러야 하기 때문에 상기 리어휠 케리어(14)는 스핀들(16)을 통하여 굽힘하중과 비틸링하중 그리고 때에 따라서 인장하중까지 받게 된다.The rear wheel carrier 14 is subjected to the bending load, the tilting load and sometimes the tensile load through the spindle 16 because the rear wheel has to roll a road surface having all kinds of environments while supporting the weight of the magnetic weight.

그리므로, 이 리어휠 케리어(14)는 상기한 하중을 분산시켜야 하는 데, 도면에서 도시된 종래의 리어휠 케리어(14)는 그 끝(30)을 트레일링 암(10)의 중간부분에서 끊어 연결함으로써 리어휠로부터 전해지는 하중이 이 끝부분에 이 부분에 집중되는 문제점이 있었다.Therefore, this rear wheel carrier 14 must distribute the above loads, which the conventional rear wheel carrier 14 shown in the figure breaks its end 30 at the middle of the trailing arm 10. There was a problem in that the load transmitted from the rear wheels by this connection was concentrated at this end.

본 발명의 목적은 상기한 문제점을 해결하기위한 것으로, 토션 비임 액슬(Torsion Beam Axle)의 리어 휠 케리어의 끝부분을 라운딩처리하여 전해지는 축하중을 이 라운딩된 부분을 따라 분산시켜 크랙의 발생가능성을 없앰으로써 예기치않은 사고를 방지하는 자동차의 리어 휠 케리어장치를 제공하는 데에 있다.DISCLOSURE OF THE INVENTION An object of the present invention is to solve the above-mentioned problems. The rounding of the end of the rear wheel carrier of the torsion beam axle disperses the congratulations transmitted along the rounded portion, thereby causing cracks. It is to provide a rear wheel carrier device for a vehicle that prevents unexpected accidents by eliminating the problem.

이러한 본 발명은, 전륜구동 자동차의 리어휠이 스핀들을 통해 장착되는 리어휠 케리어와; 이 리어휠 케리어가 장착되어 토션 비임으로 연결되는 트레일링 아암과 이 트레일링 암의 안쪽에 장착되는 스프링 시이트를 포함하는 자동차의 리어휠 케리어장치에 있어서, 상기 리어휠 케리어는 상기 트레일링 아암의 끝부분을 바깥쪽으로 라운딩시켜 리어휠을 통해 집중되는 응력을 분산시키는 것을 특징으로 하여 상기 목적을 달성할 수 있는 것이다.The present invention includes a rear wheel carrier in which a rear wheel of a front wheel drive vehicle is mounted through a spindle; A rear wheel carrier device for a vehicle comprising a trailing arm mounted to the rear wheel carrier and connected to a torsion beam and a spring seat mounted inside the trailing arm, wherein the rear wheel carrier is an end of the trailing arm.

이하 본 발명의 목적을 효과적으로 달성할 수 있는 바람직한 실시예로서 그 기술 구성 및 작용효과를 첨부한 별첨의 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, in which the technical constitution and operational effects as an exemplary embodiment can effectively achieve the object of the present invention.

도3은 본 발명이 일실시예에 따른 자동차의 리어 휠 케리어장치를 도시한 전체사시도이고, 도4는 도3의 평면도이다.3 is an overall perspective view showing a rear wheel carrier device of a vehicle according to an embodiment of the present invention, and FIG. 4 is a plan view of FIG.

전륜 구동 자동차의 리어 휠 케리어장치가 적용되는 부위에는 토션 비임(100)으로 연결된 트레일링 아암(110)과 이 트레일링 아암(110)의 안쪽에 각각 스프링시트(112)가 장착되고, 그 바깥쪽에 리어휠 케리어(120)가 장착되며 이 리어휠 케리어(120)에는 양쪽방향으로 스핀들(122)이 형성되어 있다.The trailing arm 110 connected to the torsion beam 100 and the spring seat 112 are mounted on the inside of the trailing arm 110 at the portion to which the rear wheel carrier device of the front wheel drive vehicle is applied, and on the outside of the trailing arm 110. The rear wheel carrier 120 is mounted, and the rear wheel carrier 120 is formed with the spindle 122 in both directions.

상기 리어휠 케리어(120)의 끝부분은 리어휠로부터 많은 하중을 받아 집중되는 데, 이 하중중에서 축하중의 작용은 크기 때문에 이를 완화시켜주어야 트레일링암(110)의 크랙의 발생을 방지한다.The end of the rear wheel carrier 120 is concentrated by receiving a lot of load from the rear wheel, the action during the celebration of the load is so large that it must be relaxed to prevent the occurrence of cracking of the trailing arm (110).

상기한 리어휠 케리어(120)는 전방과 후방에 각각 두 개의 끝부분을 가지고 있으나, 리어휠로부터 전해지는 하중은 전방 즉 축방향에 있는 부분에 거의 작용하므로 이부분에 집중되는 하중을 극복하기위한 방안이 필요하다.The rear wheel carrier 120 has two ends at the front and the rear, respectively, but the load transmitted from the rear wheel almost acts on the front, ie in the axial direction, so as to overcome the load concentrated on this part. I need a solution.

이러한 방안중에서 별도의 보강부재를 장착하여 집중되는 응력보다 큰 강도를 가질 수 있도록 하는 것도 있으나 이러한 방안은 집중되는 응력이 계속작용하고 이로써 보강부재를 포함한 트레일링 아암의 피로응력이 적재되면 결국 크랙이 발생하게 된다.In some of these methods, a separate reinforcement member may be installed to have a strength greater than that of the concentrated stress. However, in such a method, when the concentrated stress continues to act and the fatigue stress of the trailing arm including the reinforcing member is loaded, the crack may eventually be formed. Will occur.

따라서, 바람직하게는 상기한 집중응력이 작용하는 부분 즉 리어휠 케리어(120)와 트레일링 아암(110)이 만나는 부분에 보강부재를 덧붙이는 것보다 집중되는 응력을 분산시키는 것이 집중되는 응력을 극복하는 것 외에 그 수행과정 등에 비추어 훨씬 유리하다.Therefore, it is preferable to disperse the concentrated stress rather than adding the reinforcing member to the portion where the above-mentioned concentrated stress acts, i.e., where the rear wheel carrier 120 and the trailing arm 110 meet. In addition to doing so, it is much more advantageous in view of its performance.

그러므로, 본 실시예에서는 상기한 리어휠 케리어(120)의 끝 부분중 축방향의 부분에 응력분산수단(130)으로 라운딩처리를 하고 있다.Therefore, in this embodiment, the rounding process is performed by the stress distributing means 130 at the axial direction of the end of the rear wheel carrier 120.

그리고, 상기한 라운딩처리된 응력분산수단(130)은 바람직하게 R50의 수치로 하는 데, 이것보다 작은 수치는 원하는 응력분산효과를 얻을 수 없고 이보다 큰 수치는 트레일링 아암(110)과의 관계에서 무리를 주어 오히려 역효과를 가져 올 수 있기 때문이다.In addition, the above-mentioned rounded stress distribution means 130 is preferably set to a value of R50, but a value smaller than this cannot achieve a desired stress dispersion effect, and a value larger than this is related to the trailing arm 110. This is because it can be adversely affected by giving a bunch.

이상에서 상술한 바와같이 본 발명에 관한 자동차의 리어 휠 케리어장치는, 토션 비임 액슬의 리어 휠 케리어의 끝 부분을 라운딩처리하여 전해지는 축하중을 이 라운딩된 부분을 따라 분산시켜 크랙의 발생가능성을 없앰으로써 예기치않은 사고를 방지하는 효과가 있다.As described above, the rear wheel carrier device of the vehicle according to the present invention disperses the celebration transmitted by rounding the end portion of the rear wheel carrier of the torsion beam axle along the rounded portion to reduce the possibility of cracking. Eliminating unexpected accidents is effective.

이상에서 서술된 것은 모든 점에서 단순한 예시에 불과한 것이기 때문에, 이를 바탕으로 본 발명을 한정적으로 해석해서는 안될 것이다. 그러므로, 본 발명의 진정한 기술적 사상 및 범위 내에 존재하는 변형예 및 균등한 실시예는 모두 본 발명의 청구 범위에 속하는 것이다.Since what has been described above is merely a mere example in all respects, the present invention should not be limitedly interpreted based on this. Therefore, modifications and equivalent embodiments that fall within the true spirit and scope of the present invention shall fall within the claims of the present invention.
