Description

자동차 조향핸들의 충격흡수구조Shock-absorbing structure of steering wheel

본 고안은 자동차 조향핸들의 충격 흡수구조에 관한 것으로, 더 상세히는 자동차의 충돌사고시 조향핸들에 의한 운전자의 부상을 줄일 수 있도록 하기 위한 자동차 조향핸들의 충격 흡수구조에 관한 것이다.The present invention relates to a shock absorbing structure of a steering wheel of a vehicle, and more particularly, to a shock absorbing structure of a steering wheel of a vehicle for reducing a driver's injury caused by a steering wheel during a crash of a vehicle.

자동차 조향핸들은 자동차 충돌사고시 운전자의 부상을 가볍게 하기 위하여, 조향핸들이 운전자 쪽으로 튀어 나와서 운전자가 부상을 당하는 것과 동시에 운전자가 관성에 의하여 조향핸들에 부딪칠 때의 충격을 경감시키는 구조를 적용하기도 한다.To steer the driver's injury in the event of a car crash, the steering wheel may come out of the driver's side so that the driver may be injured and reduce the impact when the driver hits the steering wheel by inertia. .

자동차의 충돌사고시 조향핸들이 충돌에너지를 흡수하는 방법은 조향축 또는 컬럼이 축방향으로 압축되어 변형됨으로써 충격을 흡수하게 되며, 어떠한 방식이든 조향축은 2개로 나뉘어져 있고 세레이션으로 결합하여 핸들의 조작시 회전력이 전달되도록 되어 있다.The steering wheel absorbs the collision energy during the collision of the vehicle. The steering shaft or column is compressed in the axial direction and deformed to absorb shocks. In any way, the steering shaft is divided into two and combined with serrations to operate the steering wheel. Rotational force is to be transmitted.

도 1 은 종래의 자동차 조향핸들의 충격 흡수과정을 예시한 것으로, 이것은 조향축(11, 12)의 변형으로 충돌에너지를 흡수하는 방식으로, 일명 벨로우즈형이라고도 한다.1 illustrates a shock absorbing process of a conventional steering wheel of a vehicle, which is a bellows type in a manner of absorbing collision energy by deformation of steering shafts 11 and 12.

이것은 조향축(11, 12)과 컬럼튜브(21, 22)가 둘로 나뉘어져 있으며, 위 조향축(11)과 아래 조향축(12)은 세레이션결합으로 되어 있으며 위 컬럼튜브(21)와 아래 컬럼튜브( 22)는 플랜지에 의해 결합되어 있다. 그리고 아래 컬럼튜브(22)에는 벨로즈(A)가 형성되어 있다.It is divided into two steering shafts (11, 12) and column tubes (21, 22), the upper steering shaft (11) and the lower steering shaft (12) is a serration coupling, the upper column tube (21) and the lower column The tube 22 is joined by a flange. And bellows (A) is formed in the lower column tube (22).

이 형식은 1차 충격을 받으면 차체가 변형되면서 벨로즈(A)의 하부가 오므러 들고, 2차 충격을 받았을 때에는 위 조향축(11)이 벨로즈(A)의 상부를 변형시키면서 충격을 흡수하도록 되어 잇다.In this type, when the primary shock is received, the lower body of the bellows (A) is lifted as the body is deformed, and when the secondary shock is received, the upper steering shaft (11) absorbs the shock while deforming the upper part of the bellows (A). It is supposed to.

이러한 형식외에도 조향축(11, 12)이 변형되면서 충돌에너지를 흡수하는 형식 등이 있으나, 그 설명은 생략한다.In addition to this type, the steering shafts 11 and 12 are deformed to absorb collision energy, but the description thereof will be omitted.

그런데, 종래의 자동차 조향핸들의 컬럼 충격흡수 구조는 충격흡수시 조향축(11, 12)이나 컬럼튜브(21, 22)가 변형되므로 정비시 조향핸들을 새것으로 교체하여야 하며, 그 구조도 복잡한 편이어서 원가상승 및 조립시간의 연장을 초래하였다.However, the column shock absorbing structure of a conventional steering wheel of a vehicle has a steering shaft (11, 12) or column tube (21, 22) is deformed during the shock absorption, so the steering wheel must be replaced with a new one during maintenance, the structure is also complicated This led to cost increases and longer assembly times.

본 고안은 이러한 종래의 단점을 감안한 것으로, 간단한 구조로 만들고 충격흡수시 조향축이나 컬럼튜브가 변형되지 않도록 하는데 있다.The present invention has been made in view of the above-mentioned disadvantages, and it is intended to make a simple structure and to prevent deformation of the steering shaft or the column tube during shock absorption.

본 고안에 따른 자동차 조향핸들의 충격 흡수구조는 위 조향축(110)과 아래 조향축(120)은 세레이션결합으로 연결되며, 상기 위 조향축(110)과 상기 아래 조향축(120)이 위 컬럼튜브(210)와 아래 컬럼튜브(220)에 의해 내장되도록 연결되는 자동차의 조향핸들에 있어서, 상기 위 컬럼튜브(210)와 상기 아래 컬럼튜브(220)의 연결부위에 세레이션(211, 221)을 형성하되, 상기 세레이션(211, 221)에 링홈(211a, 221a)을 형성하고 상기 링홈(211a, 221a)에 플라스틱 링(R)을 끼운 후 , 상기 위 컬럼튜브(210)와 상기 아래 컬럼튜브(220)를 연결한 것에 그 특징이 있다.In the shock absorbing structure of the steering wheel of the vehicle according to the present invention, the upper steering shaft 110 and the lower steering shaft 120 are connected by serration coupling, and the upper steering shaft 110 and the lower steering shaft 120 are upper. In the steering wheel of the vehicle connected to be built by the column tube 210 and the lower column tube 220, the serration (211, 221) at the connection portion of the upper column tube 210 and the lower column tube 220 ) To form ring grooves 211a and 221a in the serrations 211 and 221 and insert the plastic ring R into the ring grooves 211a and 221a, and then the upper column tube 210 and the lower portion. It is characterized by connecting the column tube 220.

이하, 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

도 2 는 본 고안에 따른 자동차 조향핸들의 충격 흡수구조를 나타낸 사시도이고, 도 3 은 도 2 의 A부 확대도이며, 도 4 는 도 2 의 조립상태 단면도이다.Figure 2 is a perspective view showing the shock absorbing structure of the steering wheel of the vehicle according to the present invention, Figure 3 is an enlarged view of the portion A of Figure 2, Figure 4 is a cross-sectional view of the assembled state of FIG.

도 2 및 도 3 에 도시한 바와 같이, 위 컬럼튜브(210)의 상단부와 아래 컬럼튜브(220)의 하단부에 각각 세레이션(211, 221)을 형성한다. 세레이션(211, 221)은 위 컬럼튜브(210)의 경우 그 내주면에 형성하고 아래 컬럼튜브(220)의 경우 그 외주면에 형성하여 위 컬럼튜브(210)와 아래 컬럼튜브(220)를 직선적으로 연결할 수 있도록 한다.2 and 3, serrations 211 and 221 are formed at the upper end of the upper column tube 210 and the lower end of the lower column tube 220, respectively. The serrations 211 and 221 are formed on the inner circumferential surface of the upper column tube 210 and on the outer circumferential surface of the lower column tube 220 to linearly form the upper column tube 210 and the lower column tube 220. Make sure you can connect.

이때 링홈(211a, 221a)은 세레이션(211, 221)의 돌출부분을 원주방향으로 홈가공하여 형성하되, 바람직하기로는 충격흡수효과를 높이기 위하여 여러개의 링홈(211a, 221a)을 일정 간격으로 형성하고 각각의 링홈(211a, 221a)에 플라스틱 링(R)을 끼운다.In this case, the ring grooves 211a and 221a are formed by groove processing the protrusions of the serrations 211 and 221 in the circumferential direction, and preferably, a plurality of ring grooves 211a and 221a are formed at regular intervals to increase the shock absorption effect. And insert the plastic ring (R) in each ring groove (211a, 221a).

도 3및 도 4 에 도시한 바와 같이, 각각의 링홈(211a, 221a)에 플라스틱 링(R)을 끼운 후 위 컬럼튜브(210)와 아래 컬럼튜브(220)를 연결하는 방식으로 조향핸들을 조립한 후 설치하면 된다.As shown in FIGS. 3 and 4, the steering wheel is assembled by inserting the plastic ring R into each of the ring grooves 211a and 221a and then connecting the upper column tube 210 and the lower column tube 220. Install it afterwards.

이와 같이, 조립하여 설치한 본 고안에 따른 조향핸들은 1차 충격을 받으면 차체가 변형됨과 아울러 차체로부터 컬럼튜브(210, 220)에 충격이 전달되어 플라스틱 링(R)이 압축 및 변형되고, 2차 충격을 받았을 때에는 위 조향축(110)을 통하여 컬럼튜브(210, 220)에 충격이 전달되어 플라스틱 링(R)이 압축 및 변형되면서 충격을 흡수한다.In this way, the steering wheel according to the present invention assembled and installed, the vehicle body is deformed when the primary shock is received and the shock is transmitted from the vehicle body to the column tubes (210, 220), the plastic ring (R) is compressed and deformed, 2 When the vehicle is shocked, the shock is transmitted to the column tubes 210 and 220 through the upper steering shaft 110 to absorb the shock as the plastic ring R is compressed and deformed.

부언하여, 컬럼튜브(210, 220)에 충격이 전달되었을 때 링홈(211a, 221a) 부위의 압축력에 의하여 플라스틱 링(R)에 전단응력이 발생되고 이 전단응력에 의하여 플라스틱 링(R)이 변형되면서 충격을 흡수하게 된다.In addition, when the shock is transmitted to the column tubes 210 and 220, the shear stress is generated in the plastic ring R by the compressive force of the ring grooves 211a and 221a, and the plastic ring R is deformed by the shear stress. As it absorbs the shock.

따라서, 자동차 충돌사고시 플라스틱 링(R)이 변형되었거나 파손되더라도 조향핸들의 주요 구성 부품에 대한 손상을 방지할 수 있다.Therefore, even if the plastic ring R is deformed or broken in an automobile crash accident, damage to the main components of the steering wheel can be prevented.

상술한 바와 같이, 본 고안에 따른 자동차 조향핸들의 충격흡수구조는 조향핸들의 충격흡수 과정에서 조향축(110, 120)이나 컬럼튜브(210, 220)가 변형되지 않고 플라스틱 링(R)만을 새것으로 교체하면 되므로 조향핸들의 수리비가 저렴하게 소요되며, 간단한 구조로 되어 있어 조향핸들의 원가가 절감됨은 물론 조립성이 향상되는 효과가 있다.As described above, the shock absorbing structure of the steering wheel of the vehicle according to the present invention is a new plastic ring (R) without the steering shaft (110, 120) or column tube (210, 220) is deformed in the shock absorbing process of the steering handle. Since it is possible to replace the steering wheel repair cost inexpensively, the simple structure has the effect of reducing the cost of the steering wheel as well as the assembly is improved.
