Description

트레일링 링크의 포크구조 {FORK STRUCTURE OF THE TRAILING LINK}Fork structure of trailing links {FORK STRUCTURE OF THE TRAILING LINK}

본 고안은 너클과 차체의 브래킷 사이에 설치되어 휠 및 타이어의 종방향 충격을 흡수하는 트레일링 링크의 포크구조를 개선하여 보다 양호한 구조적 강성을 갖도록 한 것에 그 목적이 있다.The object of the present invention is to provide a better structural rigidity by improving the fork structure of the trailing link that is installed between the knuckle and the bracket of the vehicle body and absorbs the longitudinal impact of the wheel and tire.

본 고안은 차량의 너클(Knuckle)과 차체의 브래킷 사이에 연결설치되어 휠 및 타이어의 종방향 충격을 흡수토록한 트레일링 링크의 포크구조를 개선하여 충격에 따른 취약부인 트레일링 링크의 로드와 포크의 용접부위 파손을 방지하기에 적당하도록 된 트레일링 링크의 포크구조에 관한 것이다.The present invention is connected between the knuckle of the vehicle and the bracket of the vehicle body to improve the fork structure of the trailing link to absorb the longitudinal impact of the wheel and tire to improve the rod and fork of the trailing link, which is a weak part according to the impact. It relates to a fork structure of a trailing link adapted to prevent breakage of a welded portion of a.

일반적으로 트레일링 링크는 도1에서와 같이 너클(10)과 차체(20)의 브래킷(21) 사이에 연결되어 종방향 힘에 대한 충격흡수의 용도로 설치되는 것으로, 인장력은 차량의 선회시 R/L측의 타이어 궤적길이 차이만큼 트레일링 링크에 힘이 작용된다.In general, the trailing link is connected between the knuckle 10 and the bracket 21 of the vehicle body 20 as shown in FIG. 1 and is installed for the purpose of absorbing shock against the longitudinal force. Force is applied to the trailing link by the difference in tire track length on the / L side.

그런데 종래의 트레일링의 포크구조를 살펴보면, 도 2에서와 같이 로드(R)를 채널브래킷(C)상에 관통시켜서 용접시킨 구조로써 종방향의 힘을 받을시, 특히 인장력을 발음에 따라 채널브래킷(C)의 용접면이 로드(R)측으로 배가 부르는 변형이 생기면서 그 압축력이 중심으로 집중되므로서 결국은 로드(R)와 채널브래킷(C)의 용접부위에 크랙이 가는 현상이 발생되어 트레일링 링크가 제기능을 못하는 문제점이 있다.By the way, when looking at the fork structure of the conventional trailing, as shown in Figure 2, the rod (R) through the channel bracket (C) welded structure when receiving the longitudinal force, in particular the tensile force according to the channel bracket As the welding surface of (C) is doubled to the rod R side, the compressive force is concentrated at the center, and eventually, cracks are generated at the welded portions of the rod R and the channel bracket C. There is a problem with links not functioning properly.

따라서 본 고안은 상기의 종래 문제점을 해결하기 위해 창안한 것으로, 본 고안의 목적은 인장력을 받는 방향의 반대방향으로 포크 채널브래킷의 로드결합면을 포밍하여 곡면으로 형성해서 인장력을 받을 시 압축력으로써 채널브래킷의 모서리를 힘이 분산되게 하여 로드의 용접면DP 부하가 걸리지 않게 되어 결국은 트레일링 링크의 인장력에 대한 구조적 강도를 높이게 한다.Therefore, the present invention was devised to solve the above-mentioned conventional problem, and an object of the present invention is to form a curved surface by forming a rod engaging surface of the fork channel bracket in a direction opposite to the direction of receiving a tensile force as a compressive force when receiving a tensile force. Forces are distributed at the edges of the bracket so that the welding surface DP load of the rod is not applied, which in turn increases the structural strength against the tension of the trailing link.

상기 목적을 달성하기 위해 본 고안은 너클과 차체 사이에 연결 설치되는 트레일링 링크의 구조적 강성 증진을 위해 포크, 즉 채널브래킷의 로드결합면을 안쪽으로 배가 부른 곡면으로 형성해서 된다. 또, 이 곡면에 엠보싱 리브를 형성할 수도 있다.In order to achieve the above object, the present invention is to form a fork, that is, a rod engaging surface of the channel bracket inwardly inflated to enhance the structural rigidity of the trailing link installed between the knuckle and the vehicle body. Moreover, an embossed rib can also be formed in this curved surface.

이하에서 본 고안을 바람직한 실시예의 도면에 의해 보다 상세히 설명한다.Hereinafter, the present invention will be described in more detail by the drawings of the preferred embodiments.

본 고안에서 종래와 동일 또는 동등한 부분은 같은 부호로 표기하여 설명하기로 한다.In the present invention, the same or equivalent parts as in the prior art will be described with the same reference numerals.

너클(10)과 차체(20)의 브래킷(21)에 연결설치되어 휠 및 타이어의 종방향 힘을 받아 주는 트레일링 링크(30)를 상기 브래킷에 고정하기 위한 포크가 채널브래킷(C)으로써 로드(R)를 용접한 구성으로 이루어진 것에 있어서, 인장력에 의한 포크의 구조적 강성을 보완시키기 위해 안쪽으로 배가 부른 곡면(1)으로 포밍해서 이루어진다. 이때, 상기 곡면(1)에 엠보싱 리브(2)를 형성하면 보다 안정된 강성을 지닐 것이다.A fork for fixing the trailing link 30 connected to the knuckle 10 and the bracket 21 of the vehicle body 20 to receive the longitudinal force of the wheel and the tire to the bracket is loaded with the channel bracket C. In the configuration in which (R) is welded, it is formed by forming a curved surface 1 which is doubled inwardly to compensate for the structural rigidity of the fork due to the tensile force. At this time, forming the embossed rib 2 on the curved surface 1 will have a more stable rigidity.

한편, 본 고안에서 포크는 곡판(3)을 포밍하여 형성함으로써, 채널브래킷(C)의 로드결합면(4)과 양측 플레이트(5)간에 절곡부가 역시 라운드부(6)를 이루며 반전된 구성으로 로드(R)의 축방향 인장력에 대한 강성이 증가된다.On the other hand, in the present invention, the fork is formed by forming the curved plate 3, so that the bent portion between the rod coupling surface 4 and the both side plate 5 of the channel bracket C also forms a rounded portion 6 in an inverted configuration. Stiffness with respect to the axial tension of the rod R is increased.

즉, 트레일링 링크(30)에 미치는 인장력은 로드(R)를 통해 포크, 즉 채널브래킷(C)의 로드결합면(4)에 작용되는데, 이때 힘을 받는 반대방향으로 곡면(1)을 이루고 있어 휨이 발생될 수 없으며, 단지 응력이 채널브래킷(C)의 반전된 라운드부(6)에 서 밴딩과 압축력으로 힘을 분산하기 때문에 로드(R)와 로드결합면(4)에 용접된 부위에 큰 응력이 미치는 것을 방지할 수가 있는 것이다.That is, the tension force applied to the trailing link 30 is applied to the fork, that is, the rod engaging surface 4 of the channel bracket C through the rod R, in which the curved surface 1 is formed in the opposite direction to which the force is applied. Where no warpage can occur and only the welded portion of the rod (R) and the rod engaging surface (4) because the stress distributes the force by bending and compressing forces in the inverted round (6) of the channel bracket (C). It is possible to prevent the large stress from being applied.

이상과 같이 구성되고 작용되는 본 고안은 트레일링 링크의 포크를 단순 채널브래킷에서 곡판을 반대로 포밍하여 모서리부가 라운드지게 하여 인장력에 대한 힘의 분산을 효율적으로 하여 결국 강도 증진을 초래하여 로드와 포크의 결합부위의 크랙 등을 일소할 수 있는 유용한 고안이다.The present invention constructed and operated as described above forms the fork of the trailing link in a simple channel bracket opposite to the curved plate so that the corners are rounded, thereby effectively distributing the force to the tensile force, resulting in an increase in the strength of the rod and the fork. It is a useful design that can eliminate cracks at the coupling site.
