Abstract

본 발명은 자동차의 텔리스코픽 조향 컬럼의 길이조절장치에 관한 것으로서, 특히, 절두원추형상의 나선 슬리브를 사용하여 그의 내면이 내측칼럼의 원주 전체에 걸쳐 접촉하도록 함으로써 내측 칼럼의 변형을 방지하며, 접촉면적의 증가로 인해 체결력을 향상시킨 텔리스코픽 조향컬럼의 길이조절장치에 관한 것이다. 본 발명에 따른 조향컬럼의 길이조절장치는 내면에 경사나사부(46)가 형성되며 원주방향 슬로트(40)를 갖는 제1절두원추부(48)와, 동일한 내경을 갖는 원통부(50)로 구성되는 상부하우징(32)과; 상기 상부하우징(32)의 상기 원통부(50)의 내면을 따라 미끄럼이동 가능하게 삽입되며, 상기 하측 컬럼(36)둘레에 제1및 제2베어링(60)(62)에 의해 회전가능하게 고정되는 슬라이딩 튜브(34)와; 상기 상부하우징(32)의 제1절두원추부(48)의 내면에 형성되는 경사나사부(46)와 나사결합하여 상기 슬라이딩 튜브(34)의 외면과 마찰 접촉하는 절두원추형상의 나선슬리브(38)와; 상기 상부하우징(32)의 원주방향 슬로트(40)를 통해 삽입되어 상기 나선슬리브(38)의 일측에 고정되는 레버(42)를 포함한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for adjusting the length of a telescopic steering column of an automobile, and in particular, by using a truncated cone-shaped spiral sleeve to make its inner surface contact the entire circumference of the inner column, thereby preventing deformation of the inner column, The present invention relates to a telescopic steering column length adjusting device having improved tightening force. Steering column length adjustment device according to the present invention is formed with an inclined screw portion 46 on the inner surface and the first truncated cone portion 48 having a circumferential slot 40, the cylindrical portion 50 having the same inner diameter An upper housing 32 configured; It is slidably inserted along the inner surface of the cylindrical portion 50 of the upper housing 32, and is rotatably fixed by first and second bearings 60 and 62 around the lower column 36. A sliding tube 34; And a truncated cone-shaped spiral sleeve 38 which is screwed into the inclined screw portion 46 formed on the inner surface of the first truncated cone portion 48 of the upper housing 32 in friction contact with the outer surface of the sliding tube 34. ; The lever 42 is inserted through the circumferential slot 40 of the upper housing 32 and fixed to one side of the spiral sleeve 38.
