Description

자동차용 조향장치의 피니언 하우징과 실린더 튜브의 구속 구조{Mounting Structure Between Pinion Housing and Cylinder Tube of Steering Apparatus}Mounting Structure Between Pinion Housing and Cylinder Tube of Steering Apparatus}

본 발명은 자동차의 조향장치와 관련된 것으로서, 보다 상세하게는 피니언 기어를 내장하는 피니언 하우징과 랙 기어를 내장하는 실린더 튜브를 소정의 수단에 의하여 구속시키는 자동차용 조향장치의 피니언 하우징과 실린더 튜브의 구속 구조에 관한 것이다.The present invention relates to a steering apparatus of an automobile, and more particularly, to a pinion housing and a cylinder tube of a steering apparatus for a vehicle, in which a pinion housing incorporating a pinion gear and a cylinder tube incorporating a rack gear are restrained by a predetermined means. It's about structure.

자동차의 진행방향을 바꾸기 위한 조향장치는, 운전석에 설치되는 스티어링 휠과, 그 하측에 구비되는 스티어링 샤프트, 그리고 이 스티어링 샤프트와 연결되어 동력전달방향을 전환하는 기어 박스 등으로 이루어져 있다.The steering apparatus for changing the driving direction of the vehicle is composed of a steering wheel provided in the driver's seat, a steering shaft provided below, and a gear box connected to the steering shaft to switch the power transmission direction.

특히, 상기 기어 박스는 웜 섹터 타입, 웜 섹터 롤러 타입, 볼 앤 너트 타입, 랙 앤 피니언 타입 등이 있는데, 이 가운데 랙 앤 피니언 타입의 기어박스는 운전자의 조작력에 의해 회전되는 피니언 기어와 이 피니언 기어의 외주 일측에 밀착되는 랙 바의 랙 기어를 통해 차륜으로 동력을 전달하게 된다.In particular, the gear box includes a worm sector type, a worm sector roller type, a ball and nut type, a rack and pinion type, and the rack and pinion type gearbox includes a pinion gear and a pinion which are rotated by a driver's operating force. Power is transmitted to the wheels through the rack gear of the rack bar which is in close contact with the outer peripheral side of the gear.

여기서, 본 발명은 랙 앤 피니언 타입을 채용한 조향장치와 관련이 있는데, 이러한 형태의 조향장치에서 상기 피니언 기어는 피니언 하우징에 내장되고 랙 바는 실린더 튜브내에 내장되어, 피니언 기어와 랙 기어가 치합되는 구조를 갖는다.Here, the present invention relates to a steering apparatus employing a rack and pinion type, in which the pinion gear is embedded in the pinion housing and the rack bar is embedded in the cylinder tube, so that the pinion gear and the rack gear engage. It has a structure that becomes.

한편, 첨부도면 도 1 및 도 2에 도시된 바와 같이, 피니언 기어(미도시)가 내장되는 피니언 하우징(1)과 랙 바(미도시)가 내장되는 실린더 튜브(2)는 서로 코킹(caulking)에 의하여 구속되는데, 이러한 코킹작업은 펀치(punch)를 이용하여 하게 된다.Meanwhile, as shown in FIGS. 1 and 2, the pinion housing 1 having the pinion gear (not shown) and the cylinder tube 2 having the rack bar (not shown) are caulking each other. Constrained by, this caulking is done using a punch.

그런데, 이와 같은 펀치를 이용한 코킹에 의해 피니언 하우징(1)과 실린더 튜브(2)를 구속하는 종래의 경우에 있어서는, 펀치의 위치 및 힘의 변동에 의해 실린더 튜브(2)의 코킹부(c)가 파열되거나 하여 품질문제가 발생할 뿐만 아니라 원하는 정도의 구속력이 나오지 않게 되는 문제점이 있다.By the way, in the conventional case where the pinion housing 1 and the cylinder tube 2 are restrained by caulking using such a punch, the caulking portion c of the cylinder tube 2 is caused by variations in the position and force of the punch. There is a problem that not only the quality problem occurs due to the bursting or the binding force does not come out to the desired degree.

본 발명은 전술한 바와 같은 문제점을 해소하기 위해 안출된 것으로서, 그 목적은, 피니언 하우징과 실린더 튜브를 구속함에 있어서 실린더 튜브의 손상을 방지함과 더불어 구속력을 보다 정확하게 정할 수 있는 자동차용 조향장치의 피니언 하우징과 실린더 튜브의 구속 구조를 제공하는 데에 있다.The present invention has been made to solve the problems described above, the object of the steering device for the automobile that can more accurately determine the restraining force and to prevent damage to the cylinder tube in restraining the pinion housing and the cylinder tube. It is to provide a confinement structure of the pinion housing and the cylinder tube.

3 : 리벳3: rivet

위와 같은 목적을 달성하기 위한 본 발명에 따른 자동차용 조향장치의 피니언 하우징과 실린더 튜브의 구속 구조는, 피니언 기어를 내장하는 피니언 하우징과 랙 바를 내장하는 실린더 튜브를 구비한 랙 앤 피니언 타입의 조향장치에 있어서, 상기 피니언 하우징과 상기 실린더 튜브의 겹침 부위를 리벳팅하여 구속하는 것을 특징으로 한다.Constrained structure of the pinion housing and the cylinder tube of the steering apparatus for a vehicle according to the present invention for achieving the above object, the rack and pinion type steering apparatus having a pinion housing and a cylinder tube incorporating a rack bar pinion gear is built. In, the pinion housing and the overlapping portion of the cylinder tube is characterized in that the riveting.

여기서, 상기 리벳은 상기 피니언 하우징과 상기 실린더 튜브의 중심 축선에 대하여 양벽면에 한 개씩 체결되도록 하는 것이 바람직하다.Here, the rivets are preferably fastened one by one to both wall surfaces with respect to the central axis of the pinion housing and the cylinder tube.

이하에서는 본 발명의 바람직한 실시예를 첨부도면에 의거하여 상세히 설명하되, 종래 기술과 동일한 부위에 대해서는 동일한 참조부호를 부여하며 그 상세한 설명은 생략한다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings, the same reference numerals for the same parts as the prior art and the detailed description thereof will be omitted.

첨부도면 도 3은 본 발명에 따른 피니언 하우징과 실린더 튜브의 구속 구조를 나타낸 단면도로서, 종래 기술을 도시한 도 1의 A-A선 단면도인 도 2에 대응되는 도면이다.FIG. 3 is a cross-sectional view illustrating a constraining structure of the pinion housing and the cylinder tube according to the present invention, which corresponds to the cross-sectional view taken along line A-A of FIG.

도시된 바와 같이, 본 발명은, 피니언 기어가 내장되는 피니언 하우징(1)의 단부를 랙 바가 내장되는 실린더 튜브(2)내로 삽입하여, 피니언 하우징(1)과 실린더 튜브(2)의 벽면이 서로 겹치도록 한 뒤, 이 겸침 부위에 리벳(3)을 고정시킨다.As shown, the present invention inserts the end of the pinion housing 1 in which the pinion gear is embedded into the cylinder tube 2 in which the rack bar is embedded, so that the wall surfaces of the pinion housing 1 and the cylinder tube 2 are mutually different. After overlapping, the rivets (3) are fixed to this portion.

이 때, 상기 리벳(3)은 실린더 튜브(2)를 관통하여 피니언 하우징(1)의 벽면에 박히게 되며, 피니언 하우징(1)과 실린더 튜브(2)의 중앙을 가로지르는 축선을 중심으로 양 벽면에 각각 한 개씩의 리벳(3)을 고정하는 것이 바람직하다.At this time, the rivet (3) is penetrated into the wall of the pinion housing (1) through the cylinder tube (2), both wall surfaces around the axis crossing the center of the pinion housing (1) and the cylinder tube (2) It is preferable to fix one rivet 3 to each one.

더우기, 피니언 하우징(1)과 실린더 튜브(2)의 구속력은 리벳(3)의 굵기를 달리함으로써 조정이 가능하므로, 큰 힘으로 구속하고자 할 경우에는 보다 굵은 직경의 리벳(3)을 사용하면 된다.Furthermore, since the restraint force of the pinion housing 1 and the cylinder tube 2 can be adjusted by changing the thickness of the rivet 3, a larger diameter rivet 3 may be used when restraining with a large force. .

이와 같이, 종래의 코킹에 의하여 피니언 하우징(1)과 실린더 튜브(2)를 구속하는 구조와는 달리, 본 발명에서처럼 리벳(3)을 이용하게 되면, 실린더 튜브(2)의 리벳팅되는 부위에만 힘이 작용하게 되고 항상 동일한 힘으로 리벳팅 작업이 이루어지므로 리벳(3) 체결 전은 물론 체결 후에도 실린더 튜브(2)가 찢기는 현상은 일어나지 않게 된다.As such, unlike the structure in which the pinion housing 1 and the cylinder tube 2 are restrained by conventional caulking, when the rivet 3 is used as in the present invention, only the riveted portion of the cylinder tube 2 is used. Since the force acts and the riveting work is always performed with the same force, the phenomenon that the cylinder tube 2 is torn does not occur before or after the rivet 3 is fastened.

또, 사용되는 리벳(3)의 굵기를 여러 가지 조건에 따라 달리하기만 하면 되므로 피니언 하우징과 실린더 튜브의 구속력을 보다 정확하게 정할 수가 있다.Moreover, since the thickness of the rivet 3 used only needs to be changed according to various conditions, the restraint force of the pinion housing and the cylinder tube can be determined more accurately.

이상에서 설명한 바와 같이, 본 발명에 따른 자동차용 조향장치의 피니언 하우징과 실린더 튜브의 구속 구조에 의하면, 피니언 하우징과 실린더 튜브를 구속함에 있어서 실린더 튜브의 손상을 방지하고, 피니언 하우징과 실린더 튜브의 구속력을 보다 정확하게 정할 수 있게 됨으로써, 조향장치의 품질 향상에 기여하는 효과가 있다.As described above, according to the restraint structure of the pinion housing and the cylinder tube of the steering apparatus for automobiles according to the present invention, the restraint force of the pinion housing and the cylinder tube is prevented when the pinion housing and the cylinder tube are restrained. By being able to determine more precisely, there is an effect that contributes to the improvement of the quality of the steering apparatus.
