Abstract

PURPOSE: A clearance reduced structure makes possible to insert/withdraw an inner tube from an outer tube for telescopic operation and prevents a vibration and a noise by compensating always a clearance, thereby increasing a durability. CONSTITUTION: An opening(21) is formed by incising the outside of an outer tube(2b) and is coated with a plastic bush(3) suitable for the size of the opening. The clearance between an inner tube(2a) and the outer tube(2b) is compensated by binding the bush(3) with an elastic ring(4). Therefore, the clearance does not occur because the elastic ring(4) push in the condition that the inside of the bush(3) adheres to the surface of the inner tube(2a). Thus, a telescopic operation controlling the length of a steering column is stable and a noise and a vibration is prevented by preventing the occurrence of the clearance between the inner tube(2a) and outer tube(2b).

자동차용 스티어링 칼럼의 텔레스코픽용 유격감소구조{Interval reducing ASS'Y for telescopic of steering column for car}Interval reducing ASS'Y for telescopic of steering column for car}

본 발명은 자동차용 스티어링 칼럼의 텔레스코픽용 유격감소구조에 대한 것으로서, 더 상세하게는 이너 튜브와 아우터 튜브를 삽입하여 스티어링 칼럼을 구성하되, 텔레스코픽 기능을 위해 길이 방향으로 삽입/인출이 가능하도록 할 때, 유격이 발생치 않도록 하는데 특징이 있는 것이다.The present invention relates to a telescopic clearance reduction structure of a steering column for a vehicle, and more particularly, when the inner tube and the outer tube are inserted to configure a steering column, and when the insert / draw in the longitudinal direction is possible for the telescopic function. It is characterized by the fact that the play does not occur.

일반적으로 자동차의 조향축 하단에는 랙바가 연결되고, 상단에는 조향핸들이 축착되는 바, 상기 조향핸들은 운전자의 신체조건이나 운전자세에 맞게 스티어링 핸들의 위치를 높게 또는 낮게 조절할 수 있도록 되어 있는 바, 핸들의 위치를 높고 낮게 조절하기 위한 것이 조향축의 텔레스코픽 장치이며, 이는 도 1에서 보는 바와 같다.In general, a rack bar is connected to a lower end of a steering shaft of a car and a steering wheel is condensed at an upper side of the steering bar. It is the telescopic device of the steering shaft for adjusting the position of the handle high and low, as shown in FIG.

이러한 텔레스코픽 장치(1)는 상측 이너 튜브(2a)와 하측의 아우터 튜브(2b)를 삽입하여 이루어진 스티어링 칼럼(2)에서 상기의 아우터 튜브(2b)로부터 이너 튜브(2a)를 삽입/인출할 수 있도록 하기 위해 텔레스코픽용 모터(11)와, 워엄기구(12)와, 랙(13)으로 구성된다.The telescopic device 1 can insert / draw the inner tube 2a from the outer tube 2b in the steering column 2 formed by inserting the upper inner tube 2a and the lower outer tube 2b. It consists of a telescopic motor 11, a worm mechanism 12, and a rack 13 so as to make it possible.

이러한 텔레스코픽 장치(1)로써 이너 튜브(2a)를 삽입/인출할 때, 종래의 칼럼(2)은 슬라이딩 안내 및 유격 보상 장치가 없기 때문에 직진도 유지가 까다로울 뿐만 아니라 슬라이딩이 자유스럽지 못해 장기간 사용할 때 유격이 발생하며, 유격이 발생하게되면 수명이 짧아진다.When inserting / drawing the inner tube 2a with such a telescopic device 1, the conventional column 2 has no sliding guide and clearance compensation device, which is difficult to maintain straightness and when sliding is not free, There is play, and when it occurs, the life is shortened.

따라서 본 발명은 상기와 같은 종래의 문제점을 감안하여 이를 해결 보완하고자 안출한 것으로서, 발명의 주된 목적은 텔레스코픽 구동을 위해 아우터 튜브로부터 이너 튜브를 삽입/인출할 수 있도록 하되, 항상 유격이 보상되어 진동 및 소음이 예방될 수 있도록 하는데 있으며, 더 나가서 마모가 적어 수명이 오래갈 수 있도록 하는데 있는 것이다.Therefore, the present invention has been made in view of the above-mentioned conventional problems to solve the problem, the main object of the invention is to enable the insertion / withdrawal of the inner tube from the outer tube for telescopic drive, but the play is always compensated for vibration And to prevent noise, and to go out is less wear and long life.

이를 위한 특징적인 수단은 텔레스코픽을 위해 아우터 튜브와 이너 튜브를 삽입하여 구성한 스티어링 칼럼에 있어서, 상기한 아우터 튜브의 외주면을 절개하여 개구부를 형성한 후, 상기 개구부의 크기에 맞는 합성수지재 부시를 덮고, 부시의 둘레에서 탄성링을 감합하여 이너 튜브와 아우터 튜브 사이의 유격이 보상되도록 구성하는데 있다.A characteristic means for this is in the steering column configured by inserting the outer tube and the inner tube for telescopic, after forming the opening by cutting the outer circumferential surface of the outer tube, and covers the synthetic resin bush according to the size of the opening, The elastic ring is fitted around the bush to compensate for the play between the inner tube and the outer tube.

이하 본 발명의 실시예에 따른 구성 및 작용을 첨부 도면에 따라 상세히 설명한다.Hereinafter, the configuration and operation according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 구성을 보이기 위한 분해 사시도이고, 도 3은 본 발명의 조립 상태를 보인 단면도이다.2 is an exploded perspective view for showing the configuration of the present invention, Figure 3 is a cross-sectional view showing an assembled state of the present invention.

본 발명에서는 텔레스코픽을 위해서 아우터 튜브(2b)와 이너 튜브(2a)를 삽입하여 스티어링 칼럼(2)을 구성하되, 상기한 아우터 튜브(2b)의 외주면 일부를 절개하여 개구부(21)를 형성한 후, 상기 개구부(21)의 크기에 맞는 합성수지재 부시(3)를 덮고, 부시(3)의 둘레에서 탄성링(4)을 감합하여 이너 튜브(2a)와 아우터 튜브(2b) 사이의 유격이 보상되도록 하는 것이 중요하다.In the present invention, the outer tube (2b) and the inner tube (2a) is inserted for the telescopic configuration of the steering column (2), the outer circumferential surface of the outer tube (2b) is cut in part to form the opening 21 Covering the synthetic resin bush (3) in accordance with the size of the opening 21, the elastic ring (4) is fitted around the bush (3) to compensate for the gap between the inner tube (2a) and the outer tube (2b) It is important to make sure that it is possible.

그리고, 경우에 따라서는 아우터 튜브(2b)의 개구부(21) 및 부시(3)를 2개 이상 복수로 형성하여 접촉효율을 높일 수도 있으며, 이 경우, 상기한 복수의 부시(3)는 연결편(31)으로 연결하여 취급이 간편하도록 할 수 있다.In some cases, two or more openings 21 and bushes 3 of the outer tube 2b may be formed to increase contact efficiency. In this case, the plurality of bushes 3 may be connected to a connecting piece ( 31) for easy handling.

또, 상기한 이너 튜브(2a)와 부시(3)는 길이 방향의 세레이션홈(22)(32)들을 각각 형성하여 원주방향으로 슬립이 발생하지 않도록 하는 것이 좋다.In addition, the inner tube 2a and the bush 3 may be formed with serration grooves 22 and 32 in the longitudinal direction, respectively, so that slip does not occur in the circumferential direction.

이와 같이 구성된 본 발명은 텔레스코픽 구동을 위해 이너 튜브(2a)를 아우터 튜브(2b)로부터 인출하거나 삽입할 때는 물론 평상시에도 상기한 부시(3)의 내면이 이너 튜브(2a)의 표면에 밀착된 상태에서 탄성링(4)이 누르고 있으므로 유격이 발생하지 않게 된다.According to the present invention configured as described above, the inner surface of the bush 3 is in close contact with the surface of the inner tube 2a as well as when the inner tube 2a is withdrawn or inserted from the outer tube 2b for telescopic driving. Since the elastic ring (4) is pressed in, no play occurs.

그리고 도 3에서 보는 바와 같이 개구부(21)를 양측으로 형성하고, 각각 부시(3)를 덮은 후, 탄성링(4)으로 눌리도록 하였기 때문에 장기간 사용되어도 양측이 균형을 이룬 상태로 마모되며, 2개의 부시(3)는 연결편(31)으로 연결되어 있어 취급이 간편해 진다.As shown in FIG. 3, since the openings 21 are formed at both sides, and the bushes 3 are covered, respectively, the openings 21 are pressed by the elastic rings 4, both sides are worn in a balanced state even when used for a long time. The three bushes 3 are connected to the connecting pieces 31, so that the handling is easy.

위에서 상세히 설명한 바와 같은 본 발명은 아우터 튜브(2b)에 개구부(21)를 형성한 후, 외부에서 탄성링(4)으로 눌러 줄 수 있는 부시(3)를 사용하므로 써, 이너 튜브(2a)와 아우터 튜브(2b) 사이의 유격 발생을 예방할 수 있기 때문에 스티어링 칼럼의 길이를 조절하는 텔레스코픽 작동시 안정적이고, 진직도를 올바르게 유지할 수 있을 뿐만아니라 소음을 예방할 수 있는 등 여러 가지 많은 장점을 가지는 것이다.The present invention as described in detail above uses an inner tube (2a) and by using the bush (3) that can be pressed by the elastic ring (4) from the outside after forming the opening 21 in the outer tube (2b) Since it is possible to prevent the occurrence of play between the outer tube (2b) is stable in telescopic operation of adjusting the length of the steering column, it can have a number of advantages, such as being able to maintain the straightness as well as to prevent noise.
