Description

토오션빔식 트레일링아암 {Torsion beam type trailing arm}Torsion beam type trailing arm {Torsion beam type trailing arm}

본 발명은 토오션빔식 트레일링아암에 관한 것으로서, 더욱더 상세하게는 토오션빔의 양측부에 일측단부에 형성된 안착면이 각기 용착되는 트레일링아암을 겹판형상으로 형성하여 강도 및 내구성이 향상되도록 하는 토오션빔식 트레일링아암에 관한 것이다.The present invention relates to a torsion beam-type trailing arm, and more particularly, to form a trailing arm in which a seating surface formed at one end portion at both sides of the torsion beam is laminated to each other in a laminated shape to improve strength and durability. It relates to a torsion beam type trailing arm.

일반적으로 자동차에는 도 1에 도시하고 있는 바와 같이, 토오션빔(20)의 좌우 양측에 차량을 운행중 노면에서 받은 충격이나 진동을 완하하여 승차감이 향상되도록 하는 쇽업소버(40)가 설치되고, 상기 쇽업소버(40)가 설치된 토오션빔(20)의 좌우 양측부에는 타측부에 트레일링부쉬(30)가 삽입되는 취부공이 관통되어 형성된 트레일링아암(10)의 안착면이 외측면에 접하며 용착되어 차량의 전후방향으로 발생되는 하중을 지지하도록 하고 있다.In general, as shown in Figure 1, the shock absorber 40 is provided on the left and right sides of the torsion beam 20 to reduce the shock or vibration received from the road surface while driving to improve the riding comfort, The mounting surface of the trailing arm 10 formed by penetrating the mounting hole into which the trailing bush 30 is inserted in the other side is welded to the outside on both the left and right sides of the torsion beam 20 in which the shock absorber 40 is installed. Thus, the load generated in the front-rear direction of the vehicle is supported.

그러나 종래에는 상기 토오션빔식 트레일링아암이 일정한 두께의 세로판재 형태로 구성되어 일측부에 형성된 안착면이 토오션빔(20)의 외측면에 접하도록 직각으로 맞댄 후 용접이 이루어지는 관계로 용착강도가 미약하게 이루어지게 됨으로서, 차량을 운행중 토오션빔(20)에 발생되는 비틀림모멘트나 굽힙모멘트에 의해 상기 토오션빔(20)에 용착되어 있는 트레일링아암(10)의 안착면이 절손되어 전후방향으로 발생되는 하중을 지지하지 못하게 됨은 물론, 상기 차량에 발생되는 전후방향의 하중에 의해 차량을 운행중 각종 사고를 유발하게 되는 문제점이 있었다.However, in the related art, the torsion beam trailing arm is formed in the form of a vertical plate having a constant thickness, and thus the welding strength is performed after the seating surface formed at one side of the torsion beam is contacted at a right angle so as to contact the outer surface of the torsion beam 20. As a result of the weakness, the seating surface of the trailing arm 10 welded to the torsion beam 20 by the torsional moment or the bending moment generated in the torsion beam 20 while driving the vehicle is cut off and back. Not only does not support the load generated in the direction, there is a problem that causes various accidents while driving the vehicle by the front and rear load generated in the vehicle.

한편, 종래에도 상기 종래와 같은 문제점을 해결하기 위해 트레일링아암(10)의 두께를 증가시키거나, 토오션빔의 용접부를 양단으로 용접하여 보강하고 있으나, 이역시도 상기 트레일링아암(10)의 두께를 증가시키는 데에 재질상의 한계가 발생하게 됨은 물론, 용접품질에 따라 강도의 차이가 많이 나게 되므로 매우 까다로운 품질관리를 필요로 하게 되는 문제점이 있었다.On the other hand, in order to solve the same problem as in the prior art to increase the thickness of the trailing arm (10), or welded to the both ends of the welding portion of the torsion beam, but reinforcement, but the reverse of the trailing arm (10) Increasing the thickness, the material limitations, as well as the difference in strength depending on the welding quality, there was a problem that requires very demanding quality control.

본 발명의 목적은 상기 종래와 같은 문제점을 해결하기 위해, 트레일링아암의 일측부에 토오션빔의 외측면에 접하며 용착되는 안착면이 형성되고, 상기 안착면이 형성된 트레일링아암의 타측부에는 트레일링부쉬가 삽입되는 취부공이 형성되어 지는 것에 있어서, 상기 트레일링아암이 세로이중겹판이 되도록 파이프가 프레스가공되어 제작됨으로서, 상기 트레일링아암의 강도가 향상됨은 물론, 내구성이 향상되어 차량의 전후방향에 발생되는 하중을 보다 효과적으로 지지하게 되어 차량에 탑승하고 있는 승원의 승차감 및 안전성이 향상되도록 하는 토오션빔식 트레일링아암을 제공하는 데 있다.An object of the present invention, in order to solve the problem as described above, a seating surface is formed in contact with the outer surface of the torsion beam is welded on one side of the trailing arm, the other side of the trailing arm is formed In the case where the mounting hole into which the trailing bush is inserted is formed, the pipe is press-fabricated so that the trailing arm becomes a vertical double stack, thereby improving the strength of the trailing arm and improving the durability of the trailing arm. The present invention provides a torsion beam-type trailing arm that more effectively supports loads generated in a direction to improve ride comfort and safety of a crew occupying a vehicle.

이하, 첨부된 도면에 의하여 본 발명의 그 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail as follows.

본 발명의 토오션빔식 트레일링아암도 도 1과 도 2 및 도 3에 도시하고 있는 바와 같이, 트레일링아암(10)의 일측부에 토오션빔(20)의 외측면에 접하며 용착되는 안착면이 형성되고, 상기 안착면이 형성된 트레일링아암(10)의 타측부에는 트레일링부쉬(30)가 삽입되는 취부공(12)이 형성되어 지는 것은 종래와 같다. 단, 본 발명은 상기 트레일링아암(10)이 세로이중겹판이 되도록 파이프가 프레스가공되어 제작됨을 그 기술적 구성상의 기본 특징으로 한다.As shown in FIGS. 1, 2, and 3, the torsion beam trailing arm of the present invention has a seating surface which is welded to one side of the trailing arm 10 in contact with the outer surface of the torsion beam 20. The mounting hole 12 is formed in the other side of the trailing arm 10 having the seating surface formed therein, and the trailing bush 30 is inserted as in the related art. However, the present invention has the basic feature of the technical configuration that the pipe is press-fabricated so that the trailing arm 10 becomes a vertical double stack.

이와 같이 구성되는 본 발명은, 일측부에 토오션빔(20)의 외측면에 접하며용착되는 안착면(12)이 형성되고 타측부에는 트레일링부쉬(30)가 삽입되는 취부공(12)이 관통되어 형성된 트레일링아암(10)이 원통형의 파이프가 세로이중겹판이 되도록 프레스가공되는 것에 의해 세로판재 형태로 제작되어 토오션빔(20)의 외측면에 안착면(12)이 접하며 직각으로 양단이 용접됨으로서, 차량을 운행중 전후방향으로 발생되는 하중을 효과적으로 지지하게 된다.According to the present invention configured as described above, a mounting hole 12 is formed in one side thereof in contact with the outer surface of the torsion beam 20 and welded therein, and the mounting hole 12 in which the trailing bush 30 is inserted in the other side thereof. The trailing arm 10 formed therethrough is manufactured in the form of a vertical plate by being pressed so that the cylindrical pipe becomes a vertical double stack, and the seating surface 12 is in contact with the outer surface of the torsion beam 20 at right angles. By being welded, it is possible to effectively support the load generated in the front-rear direction while driving the vehicle.

따라서 이러한 본 발명은,트레일링아암(10)이 원통형의 파이프가 세로이중겹판이 되도록 프레스가공되는 것에 의해 세로판재 형태로 제작되어 토오션빔(20)의 외측면에 안착면(12)이 접하며 직각으로 양단이 용접됨으로서, 트레일링아암(10)의 강도가 향상됨은 물론, 내구성이 향상되어 차량의 전후방향에 발생되는 하중을 보다 효과적으로 지지하게 되어 차량에 탑승하고 있는 승원의 승차감 및 안전성이 향상되도록 하는 효과가 있다.Therefore, in the present invention, the trailing arm 10 is manufactured in the form of a vertical plate by press processing so that the cylindrical pipe is a vertical double-layer plate, the seating surface 12 is in contact with the outer surface of the torsion beam 20 By welding both ends at right angles, not only the strength of the trailing arm 10 is improved, but also the durability is improved to more effectively support the loads generated in the front and rear directions of the vehicle, thereby improving the riding comfort and safety of the occupant in the vehicle. It is effective to make.

이상에서 살펴본 바와 같이 본 발명은 트레일링아암의 일측부에 토오션빔의 외측면에 접하며 용착되는 안착면이 형성되고, 상기 안착면이 형성된 트레일링아암의 타측부에는 트레일링부쉬가 삽입되는 취부공이 형성되어 지는 것에 있어서, 상기 트레일링아암이 세로이중겹판이 되도록 파이프가 프레스가공되어 제작됨으로서, 상기 트레일링아암의 강도가 향상됨은 물론, 내구성이 향상되어 차량의 전후방향에 발생되는 하중을 보다 효과적으로 지지하게 되어 차량에 탑승하고 있는 승원의 승차감 및 안전성이 향상되도록 하는 매우 유용한 발명이다.As described above, the present invention has a seating surface formed in contact with the outer surface of the torsion beam and welded to one side of the trailing arm, and the trailing bush is inserted into the other side of the trailing arm on which the seating surface is formed. As the ball is formed, the pipe is press-fabricated so that the trailing arm becomes a vertical double stack, so that the strength of the trailing arm is improved, as well as the durability is improved, so that the load generated in the front and rear direction of the vehicle is increased. It is a very useful invention to effectively support the improved comfort and safety of the occupants in the vehicle.
