Description

자동차용 스티어링 칼럼의 틸트 조인트{TILT JOINT OF STEERING COLUMN FOR AUTOMOTIVE VEHICLE}Tilt joint of steering column for car {TILT JOINT OF STEERING COLUMN FOR AUTOMOTIVE VEHICLE}

본 발명은 스티어링 칼럼의 틸트 조인트에 관한 것으로, 보다 상세하게는 스티어링 휠의 각도를 조절하기 위한 틸트 조인트부에 있어서 부품에 대한 소요 비용을 절감하면서도 틸팅각도를 원활하게 조절할 수 있도록 하는 자동차용 스티어링 칼럼의 틸트 조인트에 관한 것이다.The present invention relates to a tilt joint of a steering column, and more particularly, in a tilt joint part for adjusting the angle of a steering wheel, a steering column for a vehicle that can smoothly adjust the tilting angle while reducing the cost for parts. Relates to the tilt joint.

일반적으로 자동차 스티어링 장치의 스티어링 칼럼에는 운전자의 신체조건이나 운전자세에 따라 스티어링 휠을 가장 편하게 조작할 수 있도록 하기 위한 틸팅기구가 구비되어 있다.In general, the steering column of the vehicle steering apparatus is provided with a tilting mechanism for allowing the steering wheel to be most conveniently operated according to the driver's physical condition or driver's posture.

이러한 틸팅기구의 구조로는 힌지부위의 위치에 따라 어퍼틸트구조와 로어틸트구조로 구분할 수가 있는데, 특히 어퍼틸트구조의 경우에 있어서는 고정기어 및 가동기어로 구성된 기어기구와 틸팅각도를 조절하기 위한 틸트 레버를 이용하게 된다.The structure of the tilting mechanism can be classified into an upper tilt structure and a lower tilt structure according to the position of the hinge portion. In the case of the upper tilt structure, the gear mechanism composed of the fixed gear and the movable gear and the tilting angle for adjusting the tilting angle Lever.

따라서, 상기 틸트 레버가 엔게이지(engage)되지 아니한 상태에서는 상기 고정기어와 가동기어가 맞물리지 않음으로써 운전자가 스티어링 휠의 위치를 변경할 수 없게 되고, 상기 틸트 레버가 인게이지된 상태에서는 틸팅기구에 구비되어 있는 스프링이 상기 고정기어와 가동기어를 치합시킴으로써 스티어링 휠의 위치를 변경시킬 수 있게 된다.Therefore, when the tilt lever is not engaged, the fixed gear and the movable gear are not engaged so that the driver cannot change the position of the steering wheel. In the state where the tilt lever is engaged, the tilting mechanism is provided in the tilting mechanism. A spring may engage the fixed gear and the movable gear to change the position of the steering wheel.

한편, 스티어링 칼럼의 틸트부위는 힌지기구에 의해 틸팅이 이루어지게 되는데, 이러한 힌지기구로는 유니버설 조인트나 차동기어의 축에 통상적으로 사용되는 스파이더(spider)라고 하는 부품이 적용되고 있다.On the other hand, the tilting portion of the steering column is tilted by a hinge mechanism, which is a component called a spider (spider) commonly used in the shaft of a universal joint or a differential gear.

그런데, 상기 스파이더는 흔히 고가의 합금강 단조품으로 제조가 되고 있는데, 이와 같이 스파이더를 적용하고 있는 틸트기구에서는 소재와 가공비용을 고려하면 자연히 비용 상승의 문제점이 있는 것이다.By the way, the spider is often made of expensive alloy steel forgings, the tilt mechanism to which the spider is applied is naturally a problem of cost increase considering the material and processing cost.

본 발명은 이러한 문제점을 해소하기 위한 것으로, 틸트각도를 원활하게 조절할 수 있으면서 틸트기구에 소요되는 부품의 비용을 절감할 수 있는 자동차용 스티어링 칼럼의 틸트 조인트를 제공하는 데에 그 목적이 있다.The present invention has been made to solve this problem, and an object thereof is to provide a tilt joint of a steering column for a vehicle that can smoothly adjust the tilt angle and reduce the cost of parts required for the tilt mechanism.

1 : 칼럼튜브 2 : 휠샤프트1: column tube 2: wheel shaft

2a : 환구체 3 : 연결수단2a: sphere 3: connecting means

4 : 탄성몰딩체4: elastic molding body

위와 같은 목적을 달성하기 위한 본 발명은, 칼럼튜브와 휠샤프트를 틸팅가능하게 연결하는 자동차용 스티어링 칼럼의 틸트 조인트에 있어서, 상기 휠샤프트의 단부에 형성되는 환형의 환구체와; 상기 환구체가 삽입되는 중공부를 구비하며 상기 칼럼튜브에 결합되는 연결수단과; 상기 연결수단의 중공부에 몰딩되어 상기 환구체를 연결수단에 플렉시블하게 고정시키는 탄성몰딩체;로 이루어진 것을 특징으로 한다.The present invention for achieving the above object, in the tilt joint of the steering column for a vehicle for tilting the column tube and the wheel shaft, an annular cylindrical body formed at the end of the wheel shaft; Connection means having a hollow portion into which the sphere is inserted and coupled to the column tube; And an elastic molding body molded in the hollow part of the connecting means to flexibly fix the ring to the connecting means.

이하 본 발명의 바람직한 실시예를 첨부된 도면을 참조로하여 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도 1은 본 발명에 따른 틸트 조인트부를 나타낸 부분단면의 정면도이고, 도 2는 도 1의 A측에서 바라본 틸트 조인트부에 대한 단면도이다.1 is a front view of a partial cross-sectional view showing a tilt joint portion according to the present invention, Figure 2 is a cross-sectional view of the tilt joint portion seen from the A side of FIG.

도시된 바와 같이, 칼럼튜브(1)의 단부에 휠샤프트(2)가 연결수단(3)을 매개로하여 결합이 되는데, 상기 연결수단(3)의 내부는 중공부로 이루어지고, 상기 휠샤프트(2)의 단부에는 상기 연결수단(3)의 중공부에 삽입되는 환형의 구형상으로 된 환구체(2a)가 형성된다.As shown, the wheel shaft (2) is coupled to the end of the column tube (1) via the connecting means (3), the inside of the connecting means (3) is made of a hollow portion, the wheel shaft ( At the end of 2), an annular spherical annulus 2a inserted into the hollow portion of the connecting means 3 is formed.

그리고, 상기 연결수단(3)의 중공부에 휠샤프트(2)의 환구체(2a)가 삽입된 상태에서 상기 연결수단(3)의 중공부와 환구체(2a) 사이의 빈 공간에는 고탄성의 합성고무와 같은 플렉시블한 재질의 탄성체가 몰딩되어 이루어지는 탄성몰딩체(4)가 충전된다.In addition, the hollow space between the hollow portion of the connecting means 3 and the cylindrical body 2a is inserted into the hollow portion of the connecting means 3 in a high elasticity. An elastic molding body 4 formed by molding an elastic body of a flexible material such as synthetic rubber is filled.

따라서, 운전자가 틸팅 레버를 조작하여 틸팅각도를 조절하고자 할 때, 휠샤프트(2)를 틸팅시키게 되면, 이 휠샤프트(2)의 단부에 형성되어 있는 환구체(2a)가 연결수단(3)의 중공부내에서 움직이게 되는데, 이러한 환구체(2a)의 변위를 기존의 스파이더와 같은 별도의 부품을 필요로 하지 않고도 연결수단(3)의 내부에 충전되어 있는 탄성몰딩체(4)가 신축적으로 흡수하면서 틸팅각도가 자유로이 조절될 수 있도록 하게 된다.Therefore, when the driver attempts to adjust the tilting angle by manipulating the tilting lever, when the driver tilts the wheel shaft 2, the sphere 2a formed at the end of the wheel shaft 2 is connected to the connecting means 3. It moves in the hollow of the, the elastic molding body 4 is filled in the interior of the connecting means (3) without the need for a separate component such as the spider, the displacement of the sphere (2a) While absorbing, the tilting angle can be adjusted freely.

이상에서 설명한 바와 같이, 본 발명에 따른 자동차용 스티어링 칼럼의 틸트 조인트는 고가의 부품 사용을 배제시키면서 스티어링 휠의 틸팅각도를 자유로이 조절할 수 있게 됨으로써, 틸트기구에 소요되는 부품에 대한 비용절감의 효과를 갖는다.As described above, the tilt joint of the steering column for automobiles according to the present invention can freely adjust the tilting angle of the steering wheel while eliminating the use of expensive parts, thereby reducing the cost of the parts required for the tilt mechanism.
