본 고안은 자동차용 핸들에 관한 것으로, 특히 조향핸들과 조향주축 사이에 가스충진부를 형성함으로써 운전중 운전자의 핸들에 충격을 완화할 수 있도록 한 것이다.The present invention relates to a steering wheel for an automobile, and in particular, by forming a gas filling unit between the steering wheel and the steering spindle to reduce the impact on the steering wheel of the driver during driving.
종래의 자동차용 핸들은 조향기둥튜브를 가지는 조향핸들과 조향주축으로 이루어져서 단순히 상기 조향핸들의 조향기둥튜브내에 조향주축이 끼워져서 고정됨으로써 운전중 불의의 사고등에 의한 운전자의 핸들에 의한 충격을 완충흡수할 수 있는 제반 조치가 전무한 상태이며, 상기 운전자의 핸들에 의한 충격을 대비하여 에어백(AIR BAG)을 설치하게 될 경우에는 별도의 설치비에 따른 비용부담이 발생하게 되는 단점이 있었다.Conventional automotive steering wheels consist of a steering wheel having a steering cylinder tube and a steering spindle, and the steering shaft is simply inserted into the steering cylinder tube of the steering wheel to be fixed to absorb shocks caused by the driver's handle due to an unexpected accident during driving. In the absence of any measures that can be taken, and in case of installing an air bag (AIR BAG) in preparation for the impact of the steering wheel of the driver, there was a disadvantage that the cost of the additional installation cost occurs.
본 고안은 종래의 이러한 문제점을 해결하기 위하여 안출된 것으로써, 조향주축이 삽입되는 조향기둥튜브내에 가스충진부를 형성하여 차량의 사고등에 의하여 상기 핸들에 대한 운전자의 충격을 완화, 흡수할 수 있도록 한 것이다.The present invention has been devised to solve such a problem in the prior art, by forming a gas filling part in the steering column tube into which the steering spindle is inserted so as to mitigate and absorb the driver's impact on the handle by an accident of the vehicle. will be.
이하 첨부도면을 참고하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 조향기둥튜브(1)를 가지는 조향핸들(2)과, 조향주축(3)으로 이루어진 자동차용 핸들(4)에 있어서, 상기 조향기둥튜브(1)는 상측이 밀폐되어서 그 내부에 원형의 돌기(5)가 형성되어져 있는 동시에 하단부에는 길이방향의 장공(6)이 관통형성되어서 이루어지며, 상기 조향주축(3)은 걸림턱(7)을 가지는 선단에 요철결합부(8)로 결합된 패킹(9)이 설치되고, 그 하부에는 관통공(10)이 형성되어서, 상기 조향기둥튜브(1)의 돌기(5)에 조향주축(3)의 걸림턱(7)이 걸려지며, 고정핀(11)이 상기 조향기둥튜브(1)의 장공(6)과 조향주축(3)의 관통공(10)에 끼워져서 조향기둥튜브(1)와 조향주축(3)의 사이에 가스충진부(12)가 형성되도록 하여서 이루어진 것이다.The present invention is a steering wheel (2) having a steering column tube (1) and a steering wheel (4) made of a steering spindle (3), the steering column tube (1) is closed in the upper side is sealed inside The projection 5 is formed at the same time the lower end of the long hole 6 in the longitudinal direction is formed through, the steering spindle 3 is coupled to the concave-convex coupling portion 8 at the tip having a locking jaw (7) Packing 9 is installed, and a through hole 10 is formed at a lower portion thereof, and the locking jaw 7 of the steering spindle 3 is caught and fixed to the protrusion 5 of the steering column tube 1. A pin 11 is inserted into the long hole 6 of the steering column tube 1 and the through hole 10 of the steering spindle 3 so that the gas filling unit is disposed between the steering column tube 1 and the steering spindle 3. It is made so that (12) is formed.
이를 좀더 상세히 설명하면 첨부도면 제1도는 본 고안의 구성도로써, 조향기둥튜브(1)는 상부가 밀폐되어져 있으며, 내측의 중간부분에 원형의 돌기(5)가 형성되어져 있으며, 하단부에는 길이방향을 따라 관통된 장공(6)이 형성되어져 있다.Detailed description of the accompanying drawings Figure 1 is a schematic view of the present invention, the steering column tube (1) is closed at the top, a circular protrusion (5) is formed in the middle portion of the inner side, the lower end in the longitudinal direction The long hole 6 which penetrated along this is formed.
또한, 조향주축(3)은 선단에 요철결합부(8)에 의하여 패킹(9)이 설치되어져 있으며, 그 바로 밑에는 원형의 걸림턱(7)이 형성되어져 있으며, 다시 그 아래에는 조향주축(3)과 직교되는 관통공(10)이 형성되어져 있어서, 상기 조향기둥튜브(1)의 돌기(5)상에 조향주축(3)의 걸림턱(7)이 얹혀지는 동시에, 상기 조향기둥튜브(1)와 조향주축(3)은 각각의 장공(6)과 관통공(10)내에 고정핀(11)이 끼워짐으로써 조향기둥튜브(1)와 조향주축(3) 선단간의 사이에 가스충진부(12)가 형성되도록 이루어져 있다.In addition, the steering spindle (3) is provided with a packing (9) by the uneven coupling portion (8) at the tip, a circular locking jaw (7) is formed immediately below the steering shaft, and the steering spindle (below) A through hole 10 perpendicular to 3 is formed so that the locking jaw 7 of the steering spindle 3 is placed on the protrusion 5 of the steering column tube 1 and the steering column tube ( 1) and the steering spindle (3) is the gas filling section between the steering column tube (1) and the steering spindle (3) tip by inserting the fixing pin (11) in each of the long hole (6) and the through hole (10) (12) is formed.
상기와 같이 구성된 본 고안의 작용효과를 설명하면, 제2도는 본 고안의 작동상태도로써, 제2도(a)는 통상적인 상태로 선단에 패킹(9)이 설치된 조향주축(3)은 걸림턱(7)이 조향기둥튜브(1)내에 끼워져서 돌기(5)상에 걸려짐으로써 가스충진부(12)가 형성되는 동시에 조향기둥튜브(1)는 실린더와 같은 역할을 하게 되며, 조향주축(3)은 피스톤과 같은 역할을 나타내게 된다.Referring to the operation and effect of the present invention configured as described above, Figure 2 is a state diagram of the operation of the present invention, Figure 2 (a) is a steering shaft (3) having a packing (9) installed on the tip in a normal state is a locking jaw (7) is inserted into the steering column tube (1) and caught on the projection (5) to form a gas filling portion 12, while the steering column tube (1) acts like a cylinder, the steering spindle ( 3) shows the same role as the piston.
이때, 조향기둥튜브(1)와 조향주축(3)간에 끼워진 고정핀(11)은 상기 가스충진부(12)에 고압가스가 충진되어 있게 되므로 조향기둥튜브(1)에 형성된 장공(6)의 하단부에 위치된 상태를 위치하게 된다.At this time, the fixing pin 11 sandwiched between the steering column tube 1 and the steering spindle 3 is filled with the high-pressure gas in the gas filling part 12 so that the long holes 6 formed in the steering column tube 1 are formed. The state is located at the lower end.
따라서, 자동차의 사고로 인한 운전자의 핸들(4)에 대한 충돌이 발생될 경우 상기 조향기둥튜브(1)가 고정핀(11)과 장공(6)에 의한 안내를 받으며 하강함으로써 상기 가스충진부(12)의 가스가 압축되면서 순간적으로 완충작용을 하게 되며(제2도(b) 참조), 상기 운전자에 대한 핸들(4)의 충격이 완화되면 조향기둥튜브(1)는 다시 고정핀(11)과 장공(6)의 안내를 받으며 원상복귀됨으로써 운전자를 보호할 수 있게 되는 것이다.Therefore, when a collision with the steering wheel 4 of the driver occurs due to an accident of the vehicle, the steering column tube 1 is guided by the fixing pin 11 and the long hole 6 and lowered so that the gas filling unit ( When the gas of 12) is compressed and momentarily buffered (see FIG. 2 (b)), when the impact of the handle 4 against the driver is alleviated, the steering column tube 1 is again fixed pin 11. Under the guidance of the supervisor (6) will be able to protect the driver by returning to the original.
이상에서 설명드린 바와 같이 본 고안은 자동차용 핸들에 있어서, 조향기둥튜브와 조향주축의 사이에 가스충진부를 형성함으로써 차량의 충격에 따른 운전자의 핸들에 대한 충격을 흡수, 완화할 수 있으므로 운전자를 보호함은 물론 조향장치에 큰 무리가 가해지는 것을 방지할 수 있는 장점을 지니는 것이다.As described above, the present invention protects the driver by forming a gas filling part between the steering column tube and the steering spindle in the steering wheel of the vehicle, thereby absorbing and mitigating the impact on the steering wheel of the driver due to the impact of the vehicle. Of course, it has the advantage of preventing a large load on the steering system.
