이와 같은 목적을 달성하기 위한 본 발명 차량용 조향장치의 볼조인트는, 랙바의 양단 내부에 축방향 외측으로 입구가 형성된 암나사부와, 상기 암나사부에 체결될 수 있도록 일측에 수나사부가 형성된 볼하우징부를 구비하는 차량용 조향장치에 있어서, 상기 암나사부의 입구 외주면에 형성된 슬릿홈과, 상기 암나사부와 수나사부의 체결시 상기 슬릿홈의 내부로 삽입될 수 있도록 상기 수나사부의 외주면에 반경방향으로 돌출 형성된 결합돌기가 구비된 것을 특징으로 한다.The ball joint of the vehicle steering apparatus according to the present invention for achieving the above object is provided with a female screw portion having an inlet formed in both ends of the rack bar in an axially outer side, and a ball housing portion having a male screw portion at one side to be fastened to the female screw portion. In the vehicle steering apparatus, a slit groove formed on the outer peripheral surface of the inlet portion of the female screw portion, and a coupling protrusion protruding radially on the outer circumferential surface of the male screw portion to be inserted into the slit groove when the female screw portion and the male screw portion is fastened. Characterized in that provided.
이하에서는 첨부한 도면을 참조하여 본 발명에 따른 차량용 조향장치의 볼조인트의 바람직한 일실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the ball joint of the vehicle steering apparatus according to the present invention.
도 2는 본 발명에 따른 차량용 조향장치의 볼조인트를 보인 단면도이다. 이에 도시된 바와 같이, 차량의 운전석에 마련된 조향휠의 동작에 의해 조향축과 함께 연동될 수 있도록 랙바(10)가 마련된다.2 is a cross-sectional view showing a ball joint of a vehicle steering apparatus according to the present invention. As shown in the drawing, the rack bar 10 is provided to be linked with the steering shaft by the operation of the steering wheel provided in the driver's seat of the vehicle.
이 랙바(10)는 금속의 원봉으로서 미도시된 중간측에 랙이 형성되어 이를 통해 조향축에서 전달되는 힘에 의해 축방향으로 이동 가능하게 설치된다.The rack bar 10 is a circular rod of metal is formed in the rack is not shown in the middle side is installed so as to be movable in the axial direction by the force transmitted from the steering shaft.
그리고 이 랙바(10)의 양측 선단 내부에는 축방향으로 형성된 원형의 홈이 마련되고, 이 홈의 내부면에는 탭가공된 암나사부(20)가 형성된다.And both ends of the rack bar 10 is provided with a circular groove formed in the axial direction, the inner surface of the groove is formed with a tabbed female threaded portion (20).
또, 랙바(10)에는 타이로드(40)가 연결 설치되는데, 이 타이로드(40)의 끝단에는 조향륜이 연결된다.In addition, the tie bar 40 is installed in the rack bar 10, the steering wheel is connected to the end of the tie rod 40.
즉, 조향륜은 운전자가 조향휠을 동작시킴에 따라 조향축과 랙바(10)와 타이로드(40)에 의해 동력이 전달되어 구동되는 것이다.That is, the steering wheel is driven by the transmission of power by the steering shaft, the rack bar 10 and the tie rod 40 as the driver operates the steering wheel.
한편, 랙바(10)와 타이로드(40)의 사이에는 이들을 연결시켜 동력을 전달시켜줄 수 있도록 볼조인트(50)가 설치된다.Meanwhile, a ball joint 50 is installed between the rack bar 10 and the tie rod 40 so as to connect them and transmit power.
이 볼조인트(50)는, 타이로드(40)와 일체로 마련되는 볼부(60)와, 이 볼부(60)가 내부에 삽입되며 랙바(10)와 연결되는 볼하우징부(70)로 이루어진다.The ball joint 50 includes a ball part 60 which is provided integrally with the tie rod 40, and a ball housing part 70 into which the ball part 60 is inserted and connected to the rack bar 10.
그리고 볼하우징부(70)의 후방측에는 랙바(10)에 형성된 암나사부(20)에 삽입될 수 있도록 외주면에 수나사부(80)가 마련된다.And a male screw portion 80 is provided on the outer circumferential surface of the ball housing portion 70 to be inserted into the female screw portion 20 formed in the rack bar 10.
또한, 본 발명에서는 별도의 부재 없이 암나사부(20)와 수나사부(80)의 견고한 결합을 위해 암나사부(20)의 외주면과 수나사부(80)의 외주면에 슬릿홈(21)과 결합돌기(81)가 마련된다.In addition, in the present invention, the slit groove 21 and the engaging protrusion on the outer circumferential surface of the female screw portion 20 and the outer circumferential surface of the male screw portion 80 for a firm coupling of the female screw portion 20 and the male screw portion 80 without a separate member ( 81).
즉, 슬릿홈(21)은 암나사부(20)가 형성된 랙바(10)의 선단 외주면에 입구(30)와 같은 외측방향으로 개구형성되는데, 후설할 결합돌기(81)가 용이하게삽입될 수 있도록 이보다 큰 폭으로 마련된다.That is, the slit groove 21 is formed in the outer direction, such as the inlet 30 to the outer peripheral surface of the front end of the rack bar 10, the female threaded portion 20 is formed, so that the engaging projection 81 to be installed later can be easily inserted It is prepared to be larger than this.
그리고, 결합돌기(81)는 수나사부(80)의 외주면에 반경방향으로 돌출되며 축방향으로 길게 형성되는데, 암나사부(20)의 내부로 수나사부(80)가 완전히 삽입된 후 슬릿홈(21)에 체결될 수 있도록 수나사부(80)가 암나사부(20)의 입구(30)로 진입되는 방향 후방측 끝단에 마련된다.In addition, the coupling protrusion 81 protrudes in the radial direction on the outer circumferential surface of the male screw portion 80 and is elongated in the axial direction. After the male screw portion 80 is completely inserted into the female screw portion 20, the slit groove 21 is formed. The male screw portion 80 is provided at the rear end in the direction in which the female screw portion 80 enters the inlet 30 of the female screw portion 20.
이와 같이 구성된 본 발명의 차량용 조향장치의 볼조인트는, 랙바(10)에 볼조인트(50)의 볼하우징부(70)를 설치할 때 암나사부(20)의 입구(30)측으로 수나사부(80)를 진입시키고 이를 회전시킴으로써 암나사부(20)와 이물림된 수나사부(80)를 그 내부로 삽입시킨다.The ball joint of the vehicle steering apparatus of the present invention configured as described above has the male thread part 80 toward the inlet 30 side of the female thread part 20 when the ball housing part 70 of the ball joint 50 is installed in the rack bar 10. By inserting and rotating the female threaded portion 20 and the external threaded portion 80 is inserted into it.
그리고 수나사부(80)에 형성된 결합돌기(81)가 반경방향으로 돌출되어있으므로 암나사부(20) 입구(30)의 축방향면과 밀착되는데, 이때 보다 강한 토오크로서 수나사부(80)를 회전시켜 입구(30)의 축방향면을 타고 결합돌기(81)가 이동되도록 한다.And because the engaging projection 81 formed in the male threaded portion 80 protrudes in a radial direction, it is in close contact with the axial surface of the inlet 30 of the female threaded portion 20, at this time by rotating the male threaded portion 80 as a stronger torque The engaging projection 81 is moved along the axial surface of the inlet 30.
이로써 결합돌기(81)는 도 3에 도시된 바와 같이, 슬릿홈(21)의 내부로 삽입되어 암나사부(20)와 수나사부(80)의 체결후 암나사부(20)의 내부에서 수나사부(80)가 회전되는 것을 방지하게 된다.As a result, the coupling protrusion 81 is inserted into the slit groove 21, as shown in FIG. 3, after the female screw portion 20 and the male screw portion 80 are fastened to the male screw portion 20. 80 is prevented from rotating.
즉, 수나사부(80)의 회전을 방지하여 수나사부(80)가 암나사부(20)의 내부에서 쉽게 이탈되지못하도록 견고히 고정되는 것이다.That is, by preventing the rotation of the male screw 80, the male screw 80 is firmly fixed so as not to be easily separated from the inside of the female screw 20.
이상에서 상세히 설명한 바와 같이, 본 발명에 따른 차량용 조향장치의 볼조인트는, 암나사부의 외주면과 수나사부의 외주면에 간단한 형상의 슬릿홈과 결합돌기를 일체로 형성함으로써 랙바와 볼하우징부를 견고히 결합시킬 수 있게된다.As described in detail above, the ball joint of the vehicle steering apparatus according to the present invention, by forming the slit groove and the engaging projection of a simple shape integrally on the outer circumferential surface of the female screw portion and the outer circumferential surface of the male screw portion can be firmly coupled to the rack bar and the ball housing. Will be.
이로써, 차량용 조향장치의 볼조인트를 결합시키기 위한 별도의 부재가 필요없게 되어 부품의 제조 및 조립이 용이해지고, 이에 소요되는 비용을 낮출 수 있어 전체적인 생산비용이 절감되는 이점이 있다.This eliminates the need for a separate member for coupling the ball joint of the vehicle steering apparatus, thereby facilitating the manufacture and assembly of parts, and thus reducing the overall cost of production.
