차량 조향장치용 랙바의 슬리브 유동방지 구조 {SLEEVE FLOW PREVENTION STRUCTURE OF RACK-BAR FOR VEHICLE STEERING GEAR}SLAVEVE FLOW PREVENTION STRUCTURE OF RACK-BAR FOR VEHICLE STEERING GEAR}

본 발명은 차량 조향장치용 랙바의 슬리브 유동방지 구조에 대한 것으로서, 특히 랙바의 전·후이동에 따른 슬리브의 유동을 방지할 수 있도록 된 차량 조향장치용 랙바의 슬리브 유동방지 구조에 관한 것이다.The present invention relates to a sleeve flow preventing structure of a rack bar for a vehicle steering apparatus, and more particularly, to a sleeve flow preventing structure of a rack bar for a vehicle steering apparatus which can prevent the flow of a sleeve due to the front and rear movement of the rack bar.

일반적으로 자동차용 스티어링장치는 조향축의 상단에 축착된 조향핸들과, 조향축의 하단에 연결하되, 로터리밸브의 내부로 이어진 인풋 샤프트와, 상기 인풋 샤프트의 하단에 연결되는 아웃풋 샤프트, 아웃풋 샤프트의 피니언에 연결된 랙바, 상기 랙바를 수용한 랙튜브로 이루어지며, 상기 랙바의 양측 끝단에는 각각 이너볼 조인트가 연결되어 차륜을 움직이도록 되어 있다.In general, the steering mechanism for automobiles is connected to a steering wheel pinned to the top of the steering shaft, and connected to the lower end of the steering shaft, the input shaft leading to the interior of the rotary valve, the output shaft connected to the bottom of the input shaft, the pinion of the output shaft It is made of a rack bar connected to the rack tube to accommodate the rack bar, the inner ends of the rack bar is connected to each inner ball joint is to move the wheel.

즉, 도 1에 도시된바와 같이 상기 랙튜브(1)와 그 내부로 입출되는 랙바(도시되어있지 않음)에는 랙부시(2)가 삽입되어 있으며, 상기 랙튜브(1)의 외주연 끝단인 결합부(1a)에는 벨로우즈관을 연결할 때, 결속력을 높이면서 기밀유지에 도움이 되도록 하기 위한 슬리브(3)가 끼워져 있다.That is, as shown in Figure 1, the rack tube (1) and the rack bar (not shown) is inserted into and out of the rack tube (2) is inserted, the outer periphery end of the rack tube (1) When connecting the bellows pipe, the coupling portion 1a is fitted with a sleeve 3 to assist in the airtightness while increasing the binding force.

그러나, 이와같이 타이로드가 연결되는 랙튜브(1)의 끝단부위에 슬리브(3)가 결합되어지면, 조향힐의 조작에 따라 반응되어 반복작동되는 랙바에 의해 랙튜브(1)의 결합부(1a)에 결합된 슬리브(3)부위로 결합된 벨로우즈관이 함께 신축과 수축하게 되고, 이로인해 상기 슬리브(3)에 지속적인 힘이 가해져 그 결합부위로부터 밀려 이동되는 문제가 있게 된다.However, when the sleeve 3 is coupled to the end of the rack tube (1) to which the tie rods are connected in this way, the coupling portion (1a) of the rack tube (1a) by the rack bar is repeatedly operated in response to the operation of the steering heel Bellows tube coupled to the sleeve (3) portion coupled to) is stretched and contracted together, thereby causing a problem that the sleeve 3 is pushed out of the coupling portion by a constant force applied to the sleeve (3).

따라서 본 발명은 상기와 같은 종래의 문제점을 감안하여 이를 해결 보완하고자 발명한 것으로서, 지속적으로 슬리브에 가해지는 힘이 랙튜브로 분산되어져 슬리브의 밀림이나 이동을 방지하도록 된 것이다.Therefore, the present invention has been invented to solve the above-mentioned problems in view of the conventional problems, and the force applied to the sleeve is continuously distributed to the rack tube to prevent the sleeve from being pushed or moved.

이를 위한 특징적인 실시 수단은 랙튜브의 결합부의 외주면에 수용홈을 형성하고, 이 수용홈에 삽입 안착되도록 돌출단이 슬리브에 형성되어 진다.Characteristic implementation means for this to form a receiving groove on the outer peripheral surface of the coupling portion of the rack tube, the protruding end is formed in the sleeve to be seated in the receiving groove.

이하 본 발명의 실시예에 따른 구성 및 작용을 첨부 도면에 따라 상세히 설명한다.Hereinafter, the configuration and operation according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 차량 조향장치용 랙바의 슬리브 유동방지 구조의 부분 단면도를 도시한 것인바, 본 발명은 종래와 같이 그 내부로 입출되는 랙바를 내장하여 그 끝부위인 결합부(1a)부위로 랙부시(2)가 삽입된 랙튜브(1)와, 이 랙튜브(1)의 결합부(1a)에 연결되는 벨로우즈관의 결속력을 높이면서 기밀을 유지하는 슬리브(3)가 끼워지되, 상기 랙튜브(1)의 결합부(1a)에는 그 외부로 둘레을 따라 수용홈(1b)이 형성되는 한편, 상기 결합부(1a)부위로 결합되는 슬리브(3)에는 상기 수용홈(1b)에 삽입 안착되는 돌출단(3a)이 형성되어 진다.Figure 2 shows a partial cross-sectional view of the sleeve flow prevention structure of the rack bar for a vehicle steering device according to the present invention, the present invention is a coupling portion (1a) that is built in the end of the rack bar to be introduced into the inside as conventional The rack tube (1) into which the rack bush (2) is inserted into the site, and the sleeve (3) to maintain airtightness while increasing the binding force of the bellows pipe connected to the engaging portion (1a) of the rack tube (1) In the coupling portion (1a) of the rack tube 1, the receiving groove (1b) is formed along the periphery thereof, while in the sleeve (3) coupled to the coupling portion (1a) the receiving groove (1b) Protruding end 3a is inserted into and seated in the groove.

이에따라, 조향힐의 조작에 따라 랙바와 벨로우즈관이 반복작동되어 랙튜브(1)의 결합부(1a)에 결합된 슬리브(3)에 지속적인 힘이 가해지면, 이 슬리브(3)의 돌출단(3a)과 랙튜브(1)의 결합부(1a)에 형성된 수용홈(1b)사이의 결합부위로 분산되어져 슬리브(3)의 밀림이나 이동이 방지되어 진다.Accordingly, when the rack bar and the bellows pipe are repeatedly operated according to the operation of the steering hill, and a continuous force is applied to the sleeve 3 coupled to the engaging portion 1a of the rack tube 1, the protrusion end of the sleeve 3 It is distributed to the coupling portion between the receiving groove (1b) formed in the coupling portion (1a) of the rack tube (1) to prevent the sleeve 3 from being pushed or moved.

위에서 상세히 설명한 바와 같은 본 발명은 랙튜브의 결합부의 외주면에 형성된 수용홈에 삽입 안착되도록 돌출단이 슬리브에 형성되어, 지속적으로 슬리브에가해지는 힘이 랙튜브로 분산되어져 슬리브의 밀림이나 이동을 방지하게 되는 효과가 있다.The present invention as described in detail above is formed in the sleeve so that the protruding end is inserted into the receiving groove formed in the outer peripheral surface of the coupling portion of the rack tube, the force applied to the sleeve is continuously distributed to the rack tube to prevent the sleeve from being pushed or moved It is effective.
