고강도 알루미늄 유죠인트 개발

A lot of studies are being conducted around the world for the improvement of vehicle’s fuel efficiency. Especially, The required strength and performance of the U Joint assembly component that transfers the steering force by driver to the steering gear were developed to be suitable to each function by developing manufacture technology such as Aluminum forging, Aluminum extrusion, Hydro-forming. For the robust design, CAE analysis was executed after the initial concept design and the result of CAE analysis was applied to other designs, thereby the optimum design was accomplished. We have made the Aluminum U-Joint assembly component which is 43% lighter than the steel U-Joint assembly component. We confirmed the possibility that the Aluminum U-Joint could be applied to a high grade fuel cell vehicle.
