이하에서는 첨부한 도면을 참조하여 본 발명에 따른 바람직한 실시예를 상세히 설명한다. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 랙바 지지장치를 보인 기어박스 단면도이다. 이에 도시된 바와 같이, 스티어링 시스템의 기어박스(110)는 입력축(113)이 내설된 밸브하우징(111)과, 랙바(130)가 내설된 랙하우징(112)이 상,하측으로 결합되어 마련된다. Figure 2 is a cross-sectional view of the gearbox showing the rack bar support according to the present invention. As shown in the figure, the gear box 110 of the steering system is provided with the valve housing 111 in which the input shaft 113 is installed, and the rack housing 112 in which the rack bar 130 is installed, are coupled up and down. .

그리고, 입력축(113)의 하단측에는 외주면에 피니언기어(121)가 형성된 피니언축(120)이 설치되고, 랙하우징(112)의 내부에는 그 중간 일측에 피니언기어(121)와 이물림되도록 랙기어(131)가 형성된 랙바(130)가 설치된다. The pinion shaft 120 having the pinion gear 121 formed on the outer circumferential surface of the input shaft 113 is installed, and the rack gear is engaged with the pinion gear 121 in the middle of the rack housing 112. The rack bar 130 on which the 131 is formed is installed.                     

한편, 랙바(130)의 후방측에는 랙바 지지장치(140)가 마련되는데, 이는 랙기어(131) 후방측에 랙하우징(112)과 일체 형성되되 그 선단이 요크플러그(180)로 인해 폐쇄되는 중공의 요크실린더(150)와 그 내부에 설치되어 슬라이딩되는 서포트요크(160)를 구비한다. Meanwhile, a rack bar support device 140 is provided at the rear side of the rack bar 130, which is integrally formed with the rack housing 112 at the rear side of the rack gear 131, but the front end thereof is closed by the yoke plug 180. The yoke cylinder 150 and the support yoke 160 which is installed and slides therein is provided.

이때, 서포트요크(160)의 전면은 랙바(130)의 배면을 감싸 밀착되도록 반원형의 홈으로 형성되고, 이 서포트요크(160)의 후방측에는 이를 랙바(130)측으로 밀어줄 수 있도록 스프링(170)이 설치된다. At this time, the front surface of the support yoke 160 is formed in a semi-circular groove to be wrapped close to the back of the rack bar 130, the spring (170) on the rear side of the support yoke 160 to push it toward the rack bar 130 side This is installed.

또한, 도 3에 도시된 바와 같이, 본 발명에서는 랙바의 회전을 방지하여 피니언기어와 랙기어 사이의 과다한 유격과 이 유격으로 인한 노이즈와 이상마모를 방지할 수 있도록 랙바의 회전을 방지하는 수단이 마련된다. In addition, as shown in Figure 3, in the present invention means for preventing the rotation of the rack bar to prevent the rotation of the rack bar to prevent excessive play between the pinion gear and the rack gear and noise and abnormal wear caused by the play Prepared.

즉, 랙바(130)의 배면에는 축방향으로 길게 랙바홈(1)을 형성하고, 이 랙바홈(1)과 마주하도록 서포트요크(160)의 전면에는 요크홈(2)을 형성하며, 이 요크홈(2)과 랙바홈(1)의 내부에는 외주 양측이 각각 삽입되도록 원통형의 다월핀(3)을 삽입하게 된다. That is, the rack bar groove 1 is formed on the rear surface of the rack bar 130 in the axial direction, and the yoke groove 2 is formed on the front surface of the support yoke 160 so as to face the rack bar groove 1. Inside the groove (2) and the rack bar groove (1) is inserted a cylindrical dowel pin (3) so that the outer peripheral both sides are respectively inserted.

이때, 랙바홈(1)은 랙바(130)의 이동거리에 대응되도록 그 축방향 길이가 결정되고, 이에 마주하는 요크홈(2)은 이 보다 짧게 형성되되 그 내부에 설치되는 다월핀(3)이 축방향으로 이탈되는 것을 방지하는 걸림턱(4)이 그 양단측에 형성된다. At this time, the rack bar groove (1) is the axial length is determined so as to correspond to the moving distance of the rack bar 130, the yoke groove (2) facing this is formed shorter than this dowel pin (3) is installed therein Locking jaws 4 are formed at both ends thereof to prevent them from escaping in the axial direction.

이로써, 요크홈(2)과 랙바홈(1)과 다월핀(3)에 의해 랙바(130)는 축방향 이동을 안내받음과 동시에 원주방향 회전이 방지되며, 보다 원활한 지지를 위해 이러한 요크홈(2)과 랙바홈(1) 그리고 다월핀(3)을 원주방향 양측에 마련한다. Thus, by the yoke groove (2) and the rack bar groove (1) and the dowel pin (3), the rack bar 130 is guided in the axial movement and at the same time prevents circumferential rotation, such yoke groove ( 2) and rack bar grooves (1) and dowel pins (3) are provided on both sides in the circumferential direction.                     

즉, 서로 마주하는 한 쌍의 요크홈(2)과 랙바홈(1)은 원주방향으로 서로 대칭되는 위치에 각각 형성되고, 그 사이에는 다월핀(3)이 각각 설치되는데, 랙바(130)의 원주방향 양측을 지지하게 된다. That is, the pair of yoke grooves 2 and the rack bar grooves 1 facing each other are formed at positions symmetrically to each other in the circumferential direction, and the dowel pins 3 are installed therebetween, and the rack bar 130 Support both sides in the circumferential direction.

이와 같이 구성된 본 발명의 차량용 스티어링 시스템의 랙바 지지장치는, 운전자가 스티어링 휠을 동작시키면 이와 연결된 입력축(113)이 그 하단측에 연결된 피니언축(120)과 함께 회전된다. In the rack bar support apparatus of the vehicle steering system of the present invention configured as described above, when the driver operates the steering wheel, the input shaft 113 connected thereto is rotated together with the pinion shaft 120 connected to the lower end side thereof.

그리고 피니언축(120)의 외주면에 형성된 피니언기어(121)가 이의 후방측에 배치된 랙바(130)의 랙기어(131)와 이물림되어 랙바(130)를 차량의 좌,우방향으로 이동시켜 이의 양단측에 연결된 타이로드 등을 통해 차륜을 동작시키게 된다. And the pinion gear 121 formed on the outer circumferential surface of the pinion shaft 120 is engaged with the rack gear 131 of the rack bar 130 disposed on the rear side thereof to move the rack bar 130 to the left and right directions of the vehicle. The wheels are operated through tie rods connected to both ends thereof.

이때, 피니언기어(121)와 랙기어(131)의 치형상이 나선형으로 마련되어 있어 이들의 이물림시 랙바(130)에는 원주방향으로의 회전력이 전달되는데, 본 발명에서는 이 랙바(130)와 서포트요크(160)에 외주 양측이 각각 삽입 설치된 다월핀(3)에 의해 회전이 방지된다. At this time, the tooth shape of the pinion gear 121 and the rack gear 131 is provided in a spiral so that the rotation force in the circumferential direction is transmitted to the rack bar 130 when these teeth are bitten, in the present invention, the rack bar 130 and the support yoke Rotation is prevented by the dowel pins 3 having the outer circumferential sides inserted into the 160, respectively.

즉, 다월핀(3)은 외주 일측이 요크홈(2)에 삽입 고정되고, 외주 타측이 랙바홈(1)에 삽입되어 그 외부에서 이동되는 랙바(130)의 축방향 이동을 안내함과 동시에 회전방향으로는 랙바(130)를 고정시키는 고정턱으로 작용한다. That is, the dowel pin (3) is fixed to the outer peripheral side is inserted into the yoke groove (2), while the outer peripheral side is inserted into the rack bar groove (1) to guide the axial movement of the rack bar 130 moved from the outside at the same time In the rotational direction acts as a fixing jaw for fixing the rack bar 130.

이상에서 상세히 설명한 바와 같이, 본 발명의 차량용 스티어링 시스템의 랙바 지지장치는, 랙바의 회전 및 비틀림에 대한 반력이 커져 랙바의 회전이 방지되고, 이로 인해 피니언기어와 랙기어의 원활한 이물림이 유지되므로 그 사이의 과다 한 유격과 노이즈 및 이상마모를 방지할 수 있는 이점이 있다. As described in detail above, the rack bar support device of the vehicle steering system of the present invention, the reaction force against the rotation and torsion of the rack bar is increased to prevent the rotation of the rack bar, thereby maintaining a smooth bite of the pinion gear and the rack gear There is an advantage to prevent excessive play and noise and abnormal wear in the meantime.
