Description

자동차용 스티어링 칼럼의 충격흡수장치{Impulse absorption apparatus of steering column for car}Impact absorption apparatus of steering column for car}

본 발명은 자동차용 스티어링 칼럼의 충격흡수장치에 대한 것으로서, 더 상세하게는 마찰력 관리가 용이하면서 제조가 쉽고 가격이 저렴한 충격흡수구조를 제공하고자 하는 것이다.The present invention relates to a shock absorbing device of a steering column for a vehicle, and more particularly, to provide a shock absorbing structure that is easy to manufacture and inexpensive, while maintaining a frictional force.

일반적으로 자동차용 스티어링 칼럼(1)은 도 1에서 보는 바와 같이 차체(2)에 고정된 채 그 속으로 통과하는 조향축(3)을 지지함은 물론 틸팅장치(4)를 가지고, 특히 전면 충돌시 완충기능을 발휘하도록 하여 가능한 운전자에게 핸들(5) 충격이 전달되지 않도록 하는 충격흡수기능이 구비되어 있다.Generally, the steering column 1 for an automobile has a tilting device 4 as well as supporting the steering shaft 3 passing therein while being fixed to the vehicle body 2 as shown in FIG. The shock absorbing function is provided so that the shock absorbing function is prevented from being 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, 충돌시 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. To overcome the friction and reduce the length.

그러나 이와 같은 종래의 충격흡수장치들은 마찰력에 의한 작용 효과가 떨어진다든가 혹은, 볼(8) 및 부시(9)를 제작하기 위한 제조공정이 추가되어야 하므로 생산성이 떨어지고, 제조원가가 높아지므로 불합리한 것이다.However, such a conventional shock absorbing device is unreasonable because the effect of the frictional force is reduced, or because the manufacturing process for manufacturing the ball 8 and the bush 9 must be added, the productivity is lowered, and the manufacturing cost is high.

따라서 본 발명은 상기와 같은 종래의 문제점을 감안하여 이를 해결 보완하고자 안출한 것으로서, 발명의 주된 목적은 내측튜브와 외측튜브를 클립으로 간단히 엮어 조립할 수 있도록 하여 생산성을 높이고 제조 원가가 크게 절감될 수 있도록 하는데 특징이 있는 것이다.Therefore, the present invention has been made in view of the conventional problems as described above to solve the problem, the main object of the invention can be assembled by simply weaving the inner tube and the outer tube with a clip to increase productivity and significantly reduce the manufacturing cost There is a characteristic to it.

이를 위한 특징적인 수단은 내측튜브의 일단을 외측튜브의 속으로 끼워 연결하는 자동차용 스티어링 칼럼에 있어서, 상기한 외측튜브의 표면 일측에 가로 방향으로 걸이홈을 형성하고, 내측튜브의 중단에는 한 쌍의 걸이 구멍을 형성한 후, ??자형으로 구부린 클립철사의 중단은 걸이홈에 걸고, 양측 끝단의 꺾음부는 각각의 걸이 구멍에 끼워 연결하여 구성하는데 있다.Characteristic means for this is in the steering column for automobiles to connect one end of the inner tube into the outer tube, to form a hook groove in the transverse direction on one side of the surface of the outer tube, a pair in the middle of the inner tube After forming the hook hole of the hook, the interruption of the clip wire bent in the shape of ?? is hooked to the hook groove, and the bent portions at both ends are inserted into the hook holes of the hook to connect.

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 구성을 보인 평단면도이고, 도 4는 본 발명의 구성을 보인 정단면도이다.3 is a plan sectional view showing the configuration of the present invention, Figure 4 is a front sectional view showing the configuration of the present invention.

도면에서 보듯이 내측튜브(6)의 일단을 외측튜브(7)의 속으로 끼워 연결하되, 상기한 외측튜브(7)의 표면 일측에는 축의 길이 방향에 대해 교차 하는 방향, 즉 가로 방향으로 걸이홈(71)을 형성하고, 외측튜브(6)의 중단에는 한 쌍의 걸이 구멍(61)을 형성한다.As shown in the drawing, one end of the inner tube 6 is inserted into the outer tube 7 to be connected, and one side of the surface of the outer tube 7 intersects the longitudinal direction of the shaft, that is, the hook groove in the horizontal direction. 71 is formed and a pair of hook holes 61 are formed in the middle of the outer tube 6.

그리고 클립철사(8)는 중단(81)을 구부려 ??자 모양으로 만든 후 양측 끝단을 꺾음부(82)로 형성하되, 상기 중단(81)은 걸이홈(71)에 걸고, 양측 끝단의 꺾음부(82)는 각각의 걸이 구멍(61)에 끼워 빠지지 않도록 연결한다.And the clip wire (8) bends the suspension (81) to form a ??-shaped and both ends are formed as a bent portion (82), the suspension (81) is hooked to the hook groove (71), the folding of both ends The connecting portion 82 is connected to each hook hole 61 so as not to be pulled out.

한편, 본 발명은 체결력을 높이기 위해 도 5에서 보는 바와 같이 달리 실시할 수 있다.On the other hand, the present invention can be carried out differently as shown in Figure 5 to increase the fastening force.

즉, 중단(81)을 걸이홈(71)에 걸고, 양측 끝단의 꺾음부(82)는 각각의 걸이 구멍(61)에 끼워 빠지지 않도록 연결하되, 상기한 클립철사(8)의 중단이 교차되는 상태로 연결하는 것이다.That is, the suspension 81 is hooked to the hook groove 71, and the bent portions 82 at both ends are connected so as not to be slipped into the respective hook holes 61, but the interruption of the clip wire 8 is crossed. To connect to a state.

이와 같이 구성된 본 발명은 스티어링 칼럼의 길이 방향으로 충격이 발생하였을 경우, 1차적으로 클립철사(8)의 폭이 벌어지면서 충격을 흡수하고, 2차적으로 외측튜브(6)의 끝단이 걸이홈(71)의 안쪽턱에 걸리면서 충격을 흡수하여 완충기능을 발휘한다.According to the present invention configured as described above, when an impact occurs in the longitudinal direction of the steering column, the width of the clip wire 8 first widens to absorb the shock, and the end of the outer tube 6 secondly has a hook groove ( 71) It absorbs a shock while being caught by the inner jaw and exerts a cushioning function.

위에서 상세히 설명한 바와 같은 본 발명은 외측튜브의 표면 일측에 가로 방향으로 걸이홈을 형성하고, 내측튜브의 중단에는 한 쌍의 걸이 구멍을 형성한 후, ??자형으로 구부린 클립철사의 중단은 걸이홈에 걸고, 양측 끝단의 꺾음부는 각각의 걸이 구멍에 끼워 연결하도록 하였기 때문에 조립 작업이 매우 간편하여 생산성이 향상될 뿐만 아니라 클립철사(8)만 추가 되므로 제조 원가가 크게 절감되는 장점이 있다.The present invention as described in detail above forms a hook groove in the transverse direction on one surface of the outer tube, and a pair of hook holes are formed in the middle tube of the inner tube, the stop of the clip wire bent in the shape of ?? In addition, since the bent portion of both ends is connected to each hook hole, the assembly work is very easy, so that the productivity is improved and only the clip wire 8 is added.
