Description

차량용 너클Car knuckle
본 발명은 차량용 너클에 관한 것으로, 보다 상세하게는 휠베어링 장착홀에 관통구멍을 폐쇄할 수 있는 보호캡 장착부를 형성해 구동륜 뿐만 아니라 종동륜에도 함께 이용될 수 있도록 구성된 차량용 너클에 관한 것이다.The present invention relates to a knuckle for a vehicle, and more particularly, to a vehicle knuckle configured to be used in a driving wheel as well as a driven wheel by forming a protective cap mounting portion capable of closing a through hole in a wheel bearing mounting hole.
[본 발명은 산업통상자원부 한국산업기술평가관리원의 우수기술연구센터(ATC) 사업의 일환으로 수행된 연구로부터 도출된 것이다(과제고유번호: 10076991, 연구과제명: 단섬유/Hot press 공법을 이용한 Steel 대비 40% 경량화된 차량용 탄소복합소재 Knuckle 개발)][This invention was derived from research conducted as part of the Advanced Technology Research Center (ATC) project of the Korea Institute of Industrial Technology Evaluation and Management of the Ministry of Trade, Industry and Energy (Task No.: 10076991, Title of Research: Short Fiber/Hot Press Method Development of Knuckle for carbon composite material for vehicles that is 40% lighter than steel)]
최근 차량용 부품은 연비 향상을 위한 제품 경량화와 비용 감소를 위한 원가 절감이 가장 큰 이슈가 되고 있다. 이러한 요구에 따라 차량의 조향장치를 구성하는 너클 제품도 소재 경량화 및 생산 공정 단순화 등을 위한 다양한 노력이 수행되고 있다.Recently, automotive parts have become the biggest issues in terms of product weight reduction to improve fuel efficiency and cost reduction to reduce costs. According to these demands, various knuckle products that make up the steering system of a vehicle are also being made to reduce the weight of materials and simplify the production process.
공정 단순화 및 원가 절감을 통한 비용 감소 방안으로 차량의 구동륜과 종동륜에 동일한 부품이 이용되도록 부품을 공용화하는 방법이 고려될 수 있다. 구동륜과 종동륜에 사용되는 부품을 동일한 구조로 형성하게 되면 부품을 동일한 공정으로 양산할 수 있게 되고 그에 따라 생산 비용 감소 및 생산성 향상을 도모할 수 있게 된다.As a method of reducing costs through process simplification and cost reduction, a method of sharing parts so that the same parts are used for the driving and driven wheels of the vehicle may be considered. When the parts used for the drive wheel and the driven wheel are formed in the same structure, the parts can be mass-produced in the same process, thereby reducing production costs and improving productivity.
그러나, 차량용 너클은 종동륜과 달리 구동륜에서는 너클과 너클 내부에 장착된 휠베어링을 관통해 구동축이 결합되어야 하기 때문에 너클의 중심부[휠베어링 장착홀]가 관통된 구조로 형성되어야 하고, 이로 인해 제품의 구동륜과 종동륜에 이용되는 제품을 공용화하기 어려운 문제가 있다.However, since the knuckle for a vehicle is a driven wheel, the driving shaft must be coupled through a knuckle and a wheel bearing mounted inside the knuckle, so that the central part of the knuckle (wheel bearing mounting hole) must be formed with a through structure. There is a problem in that it is difficult to commonize the products used for the drive and follower wheels.
이러한 상황에서 구동륜용 너클과 종동륜용 너클을 공용화하기 위한 하나의 방법으로 너클을 중심부[휠베어링 장착홀]가 폐쇄된 구조로 형성한 다음, 이러한 너클을 구동륜에 이용할 때에는 너클의 중심부에 형성된 휠베어링 장착홀에 관통구멍을 형성해 이용하도록 하는 방안이 고려될 수 있다.In this situation, the knuckle for the driving wheel and the knuckle for the driven wheel are formed as a closed structure in the center of the knuckle (wheel bearing mounting hole), and when such a knuckle is used for the driving wheel, the wheel formed in the center of the knuckle A method of forming and using a through hole in the bearing mounting hole may be considered.
그러나, 이러한 방식으로 구동륜용 너클과 종동륜용 너클을 공용화하게 되면 너클을 구동륜에 이용하고자 할 때 완성된 너클 제품의 중심부에 관통구멍을 형성하는 추가 가공을 수행해야 하기 때문에, 제품의 제조 공정이 다시 복잡해지고 추가 가공에 의해 생산 비용이 상승하게 되어 제품 공용화를 통한 원가 절감이라는 목적이 효과적으로 달성될 수 없게 된다.However, if the knuckle for the drive wheel and the knuckle for the driven wheel are shared in this manner, when the knuckle is to be used for the drive wheel, an additional process of forming a through hole in the center of the finished knuckle product must be performed, so the manufacturing process It becomes complicated again and the production cost increases by further processing, so that the goal of cost reduction through product sharing cannot be effectively achieved.
본 발명은 전술한 종래의 문제점을 해소하기 위한 것으로, 단순한 작업을 통해 차량용 너클을 구동륜용에서 종동륜용으로 전환할 수 있도록 구성되어 부품의 공용화를 달성하고, 이를 통해 제조 공정의 단순화 및 생산 비용의 저감을 도모할 수 있는 차량용 너클을 제공하는 것을 목적으로 한다.The present invention is intended to solve the above-described conventional problems, and is configured to convert a knuckle for a vehicle from a driving wheel to a driven wheel through a simple operation to achieve common use of parts, thereby simplifying the manufacturing process and producing costs.

When the knuckle is made of a carbon material such as CFRP, the knuckle can be manufactured with less weight than the conventional vehicle knuckle manufactured using a metal material such as chromium-molybdenum alloy steel, thereby reducing the weight of the parts. Through this, it is possible to improve fuel efficiency and reduce exhaust gas emissions. In addition, when the knuckle is formed of such a carbon material, it is possible to easily form a knuckle having a center portion (wheel bearing mounting hole 12) of a pierced structure without performing machining or the like.
또한, 본 발명의 일 실시예에 따른 차량용 너클에 결합될 수 있는 보호캡(80)은 플라스틱 등의 경량의 소재로 형성될 수 있다. 이러한 경량의 소재를 이용해 보호캡(80)을 형성하면 너클 부재의 중량을 더욱 감소시킬 수 있고, 소재가 가진 소정의 탄성에 의해 보호캡(80)을 너클 바디에 보다 쉽게 장착할 수 있게 된다.In addition, the protective cap 80 that can be coupled to the vehicle knuckle according to an embodiment of the present invention may be formed of a lightweight material such as plastic. When the protective cap 80 is formed using such a lightweight material, the weight of the knuckle member can be further reduced, and the protective cap 80 can be more easily mounted on the knuckle body by predetermined elasticity of the material.
