Abstract
Description
본 발명은 자동차용 스티어링 칼럼의 충격흡수장치에 대한 것으로서, 더 상세하게는 제조가 쉽고 가격이 저렴한 충격흡수구조를 제공하고자 하는 것이다.The present invention relates to a shock absorbing device for a steering column for a vehicle, and more particularly, to provide a shock absorbing structure that is easy to manufacture and inexpensive.
일반적으로 자동차용 스티어링 칼럼(1)은 도 1에서 보는 바와 같이 차체(2)에 고정된 채 틸팅장치(4)를 가지며, 그 속으로 통과하는 조향축(3)을 지지함은 물론 충돌시 완충기능을 발휘하도록 하여 가능한 운전자에게 핸들(5)을 통한 충격이 전달되지 않도록 하는 충격흡수기능이 구비되어 있다.Generally, the steering column 1 for a vehicle has a tilting device 4 fixed to the vehicle body 2 as shown in FIG. 1, and supports a steering shaft 3 passing therein as well as cushioning in a collision. A shock absorbing function is provided so as to exert a function so that a shock through the handle 5 is not transmitted to the driver as much as possible.
이와 같은 스티어링 칼럼(1)의 충격흡수기능은 충돌사고 발생시 운전자의 안전을 도모하기 위한 중요한 사항이기 때문에 근래에 많은 구조 개선이 이루어져 왔다.Since the shock absorbing function of the steering column 1 is an important matter for the driver's safety in the event of a crash, many structural improvements have been made in recent years.
즉, 충격을 흡수하도록 하기 위해 내측튜브(6)와 외측튜브(7)로 분리하여 구성한 후, 이들을 서로 삽착하되, 그 단면을 변형시킨다든가 표면에 흠을 형성한다든가 특수한 부속물을 설치하므로써 평소에는 마찰력에 의해 지지되다가 충돌시 칼럼의 길이 방향으로 작용하는 힘에 의해 그 길이가 줄어 들면서 완충기능을 하도록 하는 것이다.In other words, the inner tube (6) and the outer tube (7) to separate the configuration in order to absorb the shock, they are inserted into each other, such as modifying the cross-section or forming a flaw on the surface, usually by installing special accessories It is supported by the friction force and reduces its length by the force acting in the longitudinal direction of the column in the event of a collision, so that the buffer function.
이와 같은 목적을 달성하기 위해 안출된 근래의 한 실시예로 도 2에서와 같은 구조를 볼 수 있다.In order to achieve the above object, a structure as shown in FIG.
이는 내측튜브(6)와 외측튜브(7)의 사이에 다수의 볼(8)들을 개입시키되, 이들 볼(8)의 위치를 합성수지재 부시(9)로써 한정하여 평상시에는 마찰력이 유지되고, 충돌시에는 마찰력을 이기고 길이가 줄어들 수 있도록 한 것이다.This allows a plurality of balls 8 to intervene between the inner tube 6 and the outer tube 7, but restricts the positions of the balls 8 to the synthetic resin bush 9 so that the frictional force is normally maintained and collided. The poem is designed to overcome friction and reduce its length.
그러나 이와 같은 종래의 충격흡수장치들은 마찰력에 의한 작용효과가 떨어질 뿐만 아니라 볼(8) 및 부시(9)를 제작하기 위한 제조공정이 많이 추가 되면서 어렵고 까다로워 생산성이 떨어지며, 제조원가가 높아지는 등 여러 가지 단점이 있는 것이다.However, these conventional shock absorbers are not only less effective in the action of friction, but also a lot of manufacturing process for manufacturing the ball (8) and the bush (9) is difficult and difficult to reduce the productivity, the manufacturing cost increases, such as various disadvantages Is there.
따라서 본 발명은 상기와 같은 종래의 문제점을 감안하여 이를 해결 보완하고자 안출한 것으로서, 발명의 주된 목적은 냉측튜브와 외측튜브를 끼워 결합하되, 다수의 길이 방향의 절개홈과 간단한 원통형부시를 덧끼우는 간단한 구성 및 작업만으로 충격흡수구조가 이루어 질 수 있도록 하여 생산성을 높이고 제조 원가가 절감될 수 있도록 하는데 있다.Therefore, the present invention has been made in view of the conventional problems as described above to solve the problem, the main purpose of the invention is to combine the cold side tube and the outer tube, the plurality of longitudinal grooves and a simple cylindrical bushing It is to increase the productivity and reduce the manufacturing cost by allowing the shock absorbing structure to be achieved only with a simple configuration and work.
이를 위한 특징적인 수단은 내측튜브의 일단을 외측튜브의 속으로 끼워 연결하는 자동차용 스티어링 칼럼에 있어서, 상기한 외측튜브는 끝단에 길이 방향으로 복수의 절개홈을 형성하고, 그 절개홈이 끝나는 부분의 뒤쪽을 확관하여 직경을 넓힌 후, 상기 끝단부에 합성수지재의 부시를 억지끼움 형태로 끼워 부시가 절개홈을 가진 외측튜브의 끝단이 내측튜브의 표면으로 오므라들어 밀착력을 가질 수 있도록 하는데 있는 것이다.A characteristic means for this is in a steering column for a vehicle for connecting one end of the inner tube into the outer tube, the outer tube is formed at the end a plurality of incision groove in the longitudinal direction, the end portion of the incision groove After expanding the diameter by expanding the back, the end of the outer tube having a cutting groove is inserted into the surface of the inner tube by inserting the bush of the synthetic resin material into the end portion in the form of interference fit so as to have an adhesive force.

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 3은 본 발명의 구성에 따른 단면도로서 내측튜브(6)와 외측튜브(7)를 상호 결합하고 있음을 볼 수 있는 바, 본 발명에서의 특징은 외측튜브(7) 끝단에 길이 방향으로 복수의 절개홈(71)들을 형성하고, 그 절개홈(71)들이 끝나는 부분의 뒤쪽으로부터 확관부(72)로 확관을 실시하여 직경을 넓힌 것이다.Figure 3 is a cross-sectional view according to the configuration of the present invention can be seen that the inner tube 6 and the outer tube 7 are mutually coupled, the feature in the present invention is a plurality of longitudinal in the outer tube 7 end The incision grooves 71 are formed, and the diameter of the incision grooves 71 extends from the rear of the end portion to the expansion tube 72.
그리고 이들을 조립할 때는 상기한 외측튜브(7)의 끝단부에 내측튜브(6)를 끼운 후, 상기 외측튜브(7)의 외경에 합성수지재의 부시(8)를 억지끼움 형태로 끼워 부시(8)가 절개홈(71)을 가진 외측튜브(7)의 끝단이 내측튜브(6)의 표면으로 오므라들어 밀착력을 가질 수 있도록 하는 것이 중요하다.When assembling these, the inner tube 6 is inserted into the end of the outer tube 7, and then the bush 8 is inserted into the outer diameter of the outer tube 7 by pressing the bush 8 of the synthetic resin in the form of an interference fit. It is important that the end of the outer tube (7) having the incision groove (71) is retracted to the surface of the inner tube (6) to have an adhesive force.
이와 같이 구성된 본 발명은 길이 방향으로 충격이 발생하였을 경우, 외측튜브(7)의 내경이 내측튜브(6)의 외경에 매우 긴밀하게 밀착되어 있기 때문에 그 마찰력으로 충격을 흡수할 수 있게 되는 것이고, 이는 외측튜브(7)의 외경에 덧끼워진 부시(8)가 내, 외측 튜브(6)(7)의 밀착력을 높였기 때문에 가능한 것이다.According to the present invention configured as described above, when an impact occurs in the longitudinal direction, the inner diameter of the outer tube 7 is closely adhered to the outer diameter of the inner tube 6 so that the shock can be absorbed by the frictional force. This is possible because the bush 8 overlaid on the outer diameter of the outer tube 7 has increased the adhesion between the inner and outer tubes 6 and 7.
그리고 부시(8)는 확관부(72)에 걸려 있게 되므로 안쪽으로 밀려 들어 가지 않고 결속력을 유지시킨 채 충격을 흡수할 수 있도록 되어 있다.And because the bush 8 is hung on the expansion pipe 72, it is possible to absorb the shock while maintaining the binding force without being pushed inward.
위에서 상세히 설명한 바와 같은 본 발명은 길이 방향의 절개홈(71)들을 가진 외측튜브(7)의 외경에 덧끼운 부시(8)가 외측 튜브(6)(7)의 내경면을 내측튜브(6)의 표면에 밀착시키도록 하였기 때문에 밀착력이 높아져 충격흡수효과가 월등해 지고, 절개홈(71)과 부시(8)는 매우 간단한 구조 및 부품이기 때문에 생산성이 크게 향상될 뿐만 아니라 제조 원가를 낮출 수 있는 등 많은 장점을 가진다.According to the present invention as described in detail above, the bush 8 overlaid on the outer diameter of the outer tube 7 having the incision grooves 71 in the longitudinal direction has an inner diameter surface of the outer tube 6, 7 and the inner tube 6. Because it is in close contact with the surface of the high adhesion, the impact absorption effect is superior, and because the cutting groove 71 and the bush (8) is a very simple structure and parts, the productivity can be greatly improved and the manufacturing cost can be lowered. Has many advantages.
