Abstract

본 발명은 자동차의 조향 컬럼 샤프트에 관한 것으로써, 종래에는 차량의 정면 충격시 브라켓이 이탈되면서 하우징이 밀려들어가더라도 하우징 내부에 끼워져 잇는 길다란 샤프트가 기 길이를 그대로 유지하고 있으므로 이러한 상태에서는 조향 휠이 하우징을 따라 말려 들어가는데 한계가 있어 운전자를 조행 휠로부터 효과적으로 보호할 수가 없는 문제점이 있었다.The present invention relates to a steering column shaft of an automobile. In the related art, even when the housing is pushed in while the bracket is detached during the frontal impact of the vehicle, the long shaft that is inserted into the housing maintains the length of the steering wheel in such a state. There is a problem in that it can not effectively protect the driver from the steering wheel because there is a limit in rolling along the housing.

따라서 본 발명은 상부 몸체(42)와 하부 몸체(44)로 나뉘어져 옵접설치된 샤프트(40를 구성함에 있어서 샤프트(40)의 하부 몸체(44)를 다수개의 주름부(44a)로 형성해줌으로써 차량의 정면 충돌시 조향 컬럼의 하우징(1)을 고정하고 있는 브라켓(2)이 차체의 컬럼 브라켓에서 빠지면서 하우징(1)이 밀려들어갈 때 상기 샤프트(40)의 하부 몰체(44)에 형성된 주름부(44a)가 수축되면서 조향 휠(5)이 함께 밀려들어가게 되므로 운전자가 조향 휠(5)에 부딪힐 때의 충격을 상단히 줄일 수 있음에 따라 운전자르 사고로 부터 최대한 보호할 수 있는 유용한 발명이다.Therefore, the present invention forms the lower body 44 of the shaft 40 as a plurality of corrugations 44a in the configuration of the shaft 40 which is divided into the upper body 42 and the lower body 44 and installed opposingly. Pleat portion 44a formed in the lower molten body 44 of the shaft 40 when the housing 1 is pushed in while the bracket 2 holding the housing 1 of the steering column is pulled out of the column bracket of the vehicle body during the collision. Since the steering wheel 5 is pushed together while being contracted, it is a useful invention that can maximally protect the driver from accidents by reducing the impact when the driver hits the steering wheel 5.
