Description

텐션 링크{Tension link}Tension link

본 발명은 차량의 섀시 구성 요소인 텐션 링크에 관한 것이다.The present invention relates to a tension link that is a chassis component of a vehicle.

자동차의 설계에 경량화와 고강성의 설계는 최대의 관심사이다. 경량화와 고강성의 두가지를 만족 시키는 것은 매우 어려운 문제이기 때문이다. 연비향상 등의 이유 때문에 각 자동차 회사들이 노력을 기울이고 있는 분야는 엔진기술의 개량, 차체 경량화 등이다. 엔진 기술의 개량은 엔진 및 구동계의 효율향상과 에너지 손실의 저감 및 차체 경량화의 기술적 과제 등이 있다.Lightweight and high rigidity design is a major concern in automotive design. This is because satisfying both the light weight and high rigidity is a very difficult problem. Automotive companies are making efforts to improve engine technology and reduce body weight due to fuel efficiency improvements. Improvements in engine technology include improvements in the efficiency of engines and drive systems, reductions in energy losses, and technical challenges in weight reduction.

그러나 엔진기술과 관련해서는 약 100년 동안 이미 많은 개량과 연구가 진행되어 동일성능을 유지하며 연비를 단기간에 획기적으로 증가시키는 것에는 한계가 있기 때문에 차체 경량화를 통한 연비향상이 가장 효율적인 대안으로 떠오르고 있다.However, in terms of engine technology, many improvements and researches have already been made for about 100 years, and the improvement of fuel efficiency through weight reduction has emerged as the most efficient alternative because there is a limit to maintaining the same performance and dramatically increasing fuel economy in a short time. .

자동차 경량화를 위한 방법은 첫째, 철 구조물 을 개선하여 필요 없는 부분을 제거하는 것이고, 둘째, 알루미늄 합금과 같은 가벼운 재료를 사용하는 것이다. 전자는 저가이면서 재활용성이 큰 강(steel)을 사용하여 경량화 시키는 것이고, 후자는 재료 등에 의한 비용이 커서 주로 고급 대형 승용차에 사용되고 있다. 차체 경량화를 달성하기 위해서 최근 연구되고 있는 대표기술로는 경량재료를 이용한 차체를 들 수 있다.The method for lightening automobiles is first to improve the steel structure to remove unnecessary parts and secondly to use light materials such as aluminum alloys. The former is used to reduce the weight by using steel, which is inexpensive and highly recyclable. The latter is mainly used for high-quality large passenger cars due to the high cost of materials. Representative technologies that have been recently studied to achieve light weight of the body include a body using lightweight materials.

그러나 현재 텐션링크의 경량화에 관한 연구개발을 전무한 실정이다.However, there is no current research and development on the weight reduction of tension links.

한편, 차량용 텐션링크에 관한 기술로는 한국공개특허 제2006-0067156호의 차량의 전륜을 지지하는 멀리링크형 서스펜션의 텐션링크에 있어서, 상기 텐션링크는 2 개의 링크가 레볼루트 조인트에 의해 연결되어 차량의 범프시 또는 선회시에 일정각 범위내에서 회동가능하게 구성되는 것이 공개된 적이 있었다.Meanwhile, a technology related to a tension link for a vehicle includes a tension link of a far-link suspension supporting a front wheel of a vehicle of Korean Patent Laid-Open Publication No. 2006-0067156, wherein the tension link has two links connected by a revolute joint to the vehicle. It has been disclosed that the vehicle is configured to rotate within a certain angle at the time of bumping or turning.
