본 고안은 스티어링샤프트의 좌굴(挫屈:Collapsing) 장치에 관한 것으로서,The present invention relates to a buckling device of the steering shaft,
더욱 상세히는 충돌시의 안전성을 제고하는 구성의 자동차 조향장치에서의 스티어링샤프트의 좌굴용 절단핀볼트에 관한 것이다.More particularly, the present invention relates to a cutting pin bolt for buckling of a steering shaft in a vehicle steering apparatus having a configuration that improves safety during a collision.
자동차의 조향샤프트의 어셈블리는 외부로부터의 충격이나 충돌등에 대하여 운전자를 보호하기 위하여 중간연결부내 충돌에 의하여 좌굴하여 전체 연장길이가 수축하여 버리는 좌굴수단을 구비함으로서, 충돌시에 운전자가 조향핸들에 부딪혀 상처를 입는 것을 방지하고 있다.The steering shaft assembly of the vehicle is provided with buckling means that the entire extension length is contracted by buckling by collision in the intermediate connection in order to protect the driver against impact or collision from the outside. Preventing injuries
종래에 이러한 좌굴수단은 2개의 연결삽입관체로서 샤프트중간부를 구성하는 소위, 텔레스코픽(Telescopic)구성을 가지고, 충돌시에 1개의 샤프트가 다른 관체형샤프트내부로 인입함으로서 전체 길이가 단축되도록 하여 좌굴을 수행한다.Conventionally, such a buckling means has a so-called telescopic configuration constituting a shaft intermediate portion as two connecting insertion tubes, and when one collision is introduced into another tubular shaft in the event of a collision, the buckling is reduced. Perform.
상기의 좌굴을 수행하기 위하여 2개의 연결관체의 접속부분에 연결공을 천공하고 각 연결공을 일체로 연결하는 플라스틱수지재등의 가소성 연결재를 개재함으로서 충돌시에 이 연성 연결부가 파손되게 함으로서 좌굴이 일어나도록 구성한다. 이러한 구성이 제1도 내지 제2도에 개시된다.In order to perform the above buckling, the flexible connection part is broken in the event of a collision by drilling a connection hole in the connection part of two connection bodies and interposing a plastic connection material such as plastic resin material which connects each connection hole integrally. Configure it to happen. Such a configuration is disclosed in FIGS. 1 to 2.
제1도는본고안의 스티어링샤프트의 좌굴용 절단핀볼트가 적용되는 스티어링샤프트의 일부단면을 도시하는 측면도에는 종래 제2도의 좌굴수단이 적용된다.FIG. 1 is a side view showing a partial cross section of a steering shaft to which a cutting pin bolt for buckling of a steering shaft of the present invention is applied.
핸들축샤프트(1)와 조향기어측샤프트(2)는 양단에서 관체로서 구성되어 중간의 좌굴부위(3)에서 연결되며, 이 좌굴부위(3)는 제2도에 도시한 바와 같이 핸들축샤프트(1)와 조향기어측샤프트(2)를 상호 삽입연결되는 파이프관재로서 구성하여 연결조립하고,The handle shaft shaft 1 and the steering gear side shaft 2 are configured as tubular bodies at both ends thereof and are connected at the intermediate buckling portion 3, which is shown in FIG. 2. (1) and the steering gear side shaft (2) as a pipe pipe material to be connected to each other, assembled and assembled,
중간부에서 아세탈과 같은 플라스틱으로 각 관체의 (3,3',4,4')을 통하여 일체로 사출성형하여 연결고정체(5)를 형성한다.In the middle part, the connection fixture 5 is formed by integrally injection molding through (3,3 ', 4,4') of each tube with a plastic such as acetal.
충돌시에는상기의 좌굴부위(3)의 연결공(3,3',4,4')을 개재하여 고정되는 핸들축샤프트(1)와 조향기어측샤프트(2)는 중간의 좌굴부위(A)에서 2개의 관체를 상호 고정하는 연결고정체(5)가 파손됨으로서 좌굴이 야기되도록 한다.In the event of a collision, the handle shaft shaft 1 and the steering gear side shaft 2 fixed through the connecting holes 3, 3 ', 4, 4' of the buckling portion 3 are intermediate buckling portions A. In this case, the connecting fixture 5 fixing the two bodies to each other is broken so that buckling is caused.
상기와 같은 종래 구성의 스티어링샤프트의 좌굴수단은, 적절한 좌굴한계 충격값을 결정하기 어렵고 통상의 경우에는 작업조건(온도, 몰딩압력)에 따라서 스티어링샤프트의 좌굴값이 변하고, 2개의 관체의 연결공 사이를 사출성형하여 몰딩하기 위하여서는 상당한 크기의 치구가 필요하며 스티어링샤프트의 길이변화에 따라서 새로운 치구를 제작하여야 한다.The buckling means of the steering shaft of the conventional configuration as described above is difficult to determine the appropriate buckling limit impact value, and in general, the buckling value of the steering shaft changes according to the working conditions (temperature, molding pressure), In order to mold by injection molding, a large jig is required and a new jig must be manufactured according to the change of the length of the steering shaft.
상기의 문제점을 감안하여 본 고안의 스티어링샤프트의 좌굴용 절단핀볼트는 종래의 구성에 비하여 구성이 간단하면서도 좌굴한 계값을 최적화하여 안전성을 재고하는 구성을 개시한다.In view of the above problems, the cutting pin bolt for buckling of the steering shaft of the present invention is simple compared to the conventional configuration, but the configuration to optimize the buckling threshold value to reconsider the safety.
이하의 부수된 도면과 함께 종래의 스티어링샤프트의 아세탈몰딩방법과의 문제점과 함께 본고안의 스티어링샤프트의 좌굴용 절단핀볼트를 더욱 상세하게 설명한다.The cutting pin bolt for buckling of the steering shaft of the present invention will be described in more detail together with the problems of the conventional acetal molding method of the steering shaft together with the accompanying drawings.
제1도는 본고안의 스티어링샤프트의 좌굴용 절단핀볼트가 적용되는 스티어링샤프트의 일부단면을 도시하는 측면도, 제3도는 본고안의 스티어링샤프트의 좌굴용 절단핀볼트를 도시하는 제1도의 A 해당부의 단면도, 제4도는 본 고안의 스티어링샤프트의 좌굴용 절단핀볼트의 좌굴핀을 도시하는 평면도, 제5도는 본 고안의 스티어링샤프트의 좌굴용 절단핀볼트의 좌굴상태를 도시하는 설명도이다.FIG. 1 is a side view showing a partial cross section of a steering shaft to which the buckling cutting pin bolt of the steering shaft of the present invention is applied, FIG. 3 is a sectional view of the relevant part of FIG. 1 showing a buckling cutting bolt of the steering shaft of the present invention, 4 is a plan view showing a buckling pin of the cutting pin bolt for buckling of the steering shaft of the present invention, Figure 5 is an explanatory diagram showing a buckling state of the cutting pin bolt for buckling of the steering shaft of the present invention.
본고안의 스티어링샤프트의 좌굴용 절단핀볼트(20)는 제3도에서와 같이, 핸들축샤프트(1)의 연결관통공(13)과 조향기어측샤프트(2)의 연결공(14)사이에 직선 핀볼트형상의 삽입핀이다.The cutting pin bolt for buckling 20 of the steering shaft of the present invention is disposed between the connecting hole 13 of the steering shaft shaft 1 and the connecting hole 14 of the steering gear side shaft 2, as shown in FIG. This is a straight pin bolt insertion pin.
상기의 절단핀볼트(20)는 핸들축샤프트(1)와 조향기어측샤프트(2)는 벽체가 교차하는 위치(P)에서 요입절단부(21,22)를 각각 양단에 가지고 그 중간부는 나사산을 가지는 볼트체(23)를 구성한다. 볼트체(23)에 대향하는 상기 핸들축샤프트(1)의 연결관통공(13)에도 역시 나사산이 형성되어 나사접속한다. 요입절단부(21)의 어느하나 측에는 나사홈(24)을 가진 볼트두부(25)체를 접시머리두부형상으로 구성하여 드라이버등으로 조립할 수 있게 한다.The cutting pin bolt 20 has a handle shaft shaft 1 and a steering gear side shaft 2 having recesses 21 and 22 at both ends thereof at a position P where a wall intersects, and a middle portion thereof has a screw thread. The branch constitutes the bolt body 23. A thread is also formed in the connecting through hole 13 of the handle shaft shaft 1 opposite to the bolt body 23 so as to be screwed. On either side of the concave cutting section 21, the bolt head 25 body having a screw groove 24 is formed in the shape of a dish head to be assembled by a driver or the like.
상기와 같이 절단용 핀체에 나사산을 구비하는 이유는 단순히 핀형상의 절단핀을 사용하는 경우, 압입에도 불구하고 조향회전력과 충격에 의하여 절단핀이 이탈하는 문제점이 발생하는 발견되었기 때문이다.The reason why the thread is provided in the cutting pin body as described above is that, in the case of simply using a pin-shaped cutting pin, a problem in which the cutting pin detaches due to steering rotational power and impact despite the indentation has been found.
요입절단부(21,22)는 플라스틱소재의 절단핀볼트(20)의 양단이 만입하여 충격에 의하여 절단, 탈락되기에 용이한 형상이면 무방하고 상기의 절단핀볼트(20)의 소재, 만입도, 절단핀볼트의 직경 등은 충격에 의한 좌굴의 설계치에 따라서 결정됨은 선원에서 언급한 바와같다.The indentation cutting portions 21 and 22 may be shaped so that both ends of the cutting pin bolt 20 of the plastic material are indented and easily cut and dropped by impact, and the material, the degree of indentation of the cutting pin bolt 20, The diameter of the cutting pin bolt, etc. is determined by the design value of the buckling due to impact, as mentioned in the source.
제4도는 본고안의 스티어링샤프트의 좌굴용 절단핀볼트의 좌굴핀을 도시하고 제5도는 본고안의 스티어링샤프트의 좌굴용 절단핀볼트의 좌굴이 발생되는 순간의 요입절단부(21,22)가 분리절단된 볼트체(23)를 도시한다.4 shows the buckling pins of the cutting pin bolts for buckling of the steering shaft of the present invention, and FIG. 5 shows that the recessed cuts 21 and 22 are separated and cut at the moment when the buckling of the cutting pin bolts of the buckling of the steering shaft of the present invention occurs. The bolt body 23 is shown.
이상과 같은 본고안의 스티어링샤프트의 좌굴용 절단핀볼트는 종래의 일체형의 사출성형체 또는 단순 압입 절단핀대신 볼트형의 절단핀을 사용함으로서 설계치에 가장 근접한 값에서 좌굴이 발생하게 할 수 있고 조립 또한 상기의 절단핀을 나사조립함으로서 이루어짐과 동시에 볼트고정이 되므로 반복적인 회전과 충격에도 핀볼트가 이탈하지 않게 하는 유용한 고안인 것이다.The above-described cutting pin bolts for buckling of the steering shaft of the present invention can use a bolt-type cutting pin instead of a conventional integral injection molded body or a simple press-cutting pin, so that the buckling can be generated at the value closest to the design value. It is a useful design to prevent pin bolts from falling off even after repeated rotation and impact because the bolt is fixed at the same time made by assembling the cutting pin.
