본 발명은 래틀 노이즈가 감소되는 조향장치에 관한 것이다. 보다 상세하게는, 서포트 요크의 결합홈에 삽입되는 결합돌기를 통해 서포트 요크에 장착되는 탄성 부재를 형성시킴으로써 서포트 요크의 축 방향 및 반경 방향의 진동 및 충격을 흡수하여 래틀 노이즈가 감소되는 조향장치에 관한 것이다.The present invention relates to a steering apparatus in which rattle noise is reduced. More specifically, by forming an elastic member mounted to the support yoke through the engaging projection inserted into the coupling groove of the support yoke to the steering device to absorb the vibration and shock in the axial and radial direction of the support yoke to reduce the rattle noise It is about.

자동차의 조향장치는 자동차의 앞바퀴가 선회하는 회전 중심을 운전자가 임의로 변경하여 원하는 방향으로 자동차를 진행시킬 수 있게 하는 장치이다.The steering device of the vehicle is a device that allows the driver to arbitrarily change the rotation center of the front wheel of the vehicle to move the vehicle in a desired direction.

도 1은 종래 기술에 따른 자동차의 조향장치를 나타내는 개략도이다.1 is a schematic view showing a steering apparatus of a vehicle according to the prior art.

도 1에서 도시하는 바와 같이 종래 기술에 따른 자동차의 조향장치는 운전자가 조향휠(101)을 회전시킴에 따라 조향휠(101)과 함께 회전하는 피니언축(103) 및 양단이 바퀴(105)에 연결되되 피니언축(103)의 회전에 따라 직선 운동을 하는 랙바(107)를 포함하여 구성된다.As shown in FIG. 1, a steering apparatus of a vehicle according to the related art includes a pinion shaft 103 and both ends of the steering wheel 101 rotating together with the steering wheel 101 as the driver rotates the steering wheel 101. It is configured to include a rack bar 107 connected to the linear motion in accordance with the rotation of the pinion shaft (103).

피니언축(103)의 외주면에는 피니언 기어(109)가 형성되고, 랙바(107)의 외주면 일측에는 피니언 기어(109)에 맞물리는 랙 기어(111)가 형성되어 있다.The pinion gear 109 is formed on the outer circumferential surface of the pinion shaft 103, and the rack gear 111 meshing with the pinion gear 109 is formed on one side of the outer circumferential surface of the rack bar 107.

따라서, 피니언축(103)의 회전에 따라 랙바(107)가 축 방향으로 직선 운동을 하게 되고, 랙바(107)의 직선 운동에 따라 양쪽 바퀴(105)의 방향이 변화하게 된다. 즉, 피니언축(103) 및 랙바(107)를 통해 운전자가 원하는 방향으로 자동차를 주행할 수 있게 되는 것이다.Accordingly, the rack bar 107 linearly moves in the axial direction as the pinion shaft 103 rotates, and the directions of both wheels 105 change according to the linear motion of the rack bar 107. That is, through the pinion shaft 103 and the rack bar 107 it is possible for the driver to drive the car in the desired direction.

한편, 피니언 기어(109)와 랙 기어(111)의 맞물림이 느슨해지면 피니언축(103)의 회전력이 랙바(107)에 원활하게 전달되지 못하게 되는 한편 소음이나 진동이 발생하는 문제가 있으므로, 피니언축(103)을 향해 랙바(107)를 일정한 힘으로 밀어 줌으로써 피니언 기어(109)와 랙 기어(111)의 맞물림을 유지하여야 한다.On the other hand, when the engagement between the pinion gear 109 and the rack gear 111 is loosened, since the rotational force of the pinion shaft 103 is not smoothly transmitted to the rack bar 107, there is a problem that noise or vibration occurs. The pinion gear 109 and the rack gear 111 should be engaged by pushing the rack bar 107 with a constant force toward the 103.

도 2는 종래 기술에 따른 서포트 요크를 나타내는 부분 단면도이다.2 is a partial cross-sectional view showing a support yoke according to the prior art.

도 2에서 도시하는 바와 같이 종래 기술에 따른 서포트 요크(201)는 전단이 랙바(107)의 외주면에 접하도록 오목하게 형성되고 후단은 요크 스프링(203) 및 요크 플러그(205)에 의해 랙바(107) 쪽으로 지지된다.As shown in FIG. 2, the support yoke 201 according to the related art is recessed so that the front end is in contact with the outer circumferential surface of the rack bar 107, and the rear end is the rack bar 107 by the yoke spring 203 and the yoke plug 205. ) Is supported.

요크 플러그(205)는 외주면에 나사산이 형성되어 있어서 랙 하우징(207)에 결합되는데, 요크 플러그(205)의 후단에는 락너트(Lock Nut: 209)가 구비되어 요크 플러그(205)가 랙 하우징(207)으로부터 이탈하는 것을 방지한다.The yoke plug 205 is threaded on the outer circumferential surface thereof and is coupled to the rack housing 207. A lock nut 209 is provided at the rear end of the yoke plug 205 so that the yoke plug 205 is provided with the rack housing 207. ) To prevent deviation.

한편, 서포트 요크(201)와 요크 플러그(205) 사이에는 완충 부재(211)가 구비되어 있는데, 자동차의 주행 중 바퀴로부터의 랙바(107)를 거쳐 전달되는 역입력에 의해 서포트 요크(201)와 요크 플러그(205)가 서로 부딪혀서 발생하는 소음 또는 진동을 감소시켜 준다.Meanwhile, a buffer member 211 is provided between the support yoke 201 and the yoke plug 205. The support yoke 201 and the support yoke 201 are provided by the reverse input transmitted through the rack bar 107 from the wheel while the vehicle is being driven. The yoke plugs 205 reduce the noise or vibration caused by the collision with each other.

그런데, 이러한 종래 기술의 경우 서포트 요크(201) 및 요크 플러그(205)의 축 방향의 진동이나 충격을 감소시킬 수 있을 뿐 서포트 요크(201)의 외주면과 랙 하우징(207)의 내주면 사이, 즉 서포트 요크(201)의 반경 방향의 진동이나 충격은 감소시키지 못하는 문제점이 있었다.By the way, such a prior art can reduce the vibration or impact of the support yoke 201 and the yoke plug 205 in the axial direction, but between the outer circumferential surface of the support yoke 201 and the inner circumferential surface of the rack housing 207, that is, the support. There was a problem in that the vibration or shock in the radial direction of the yoke 201 could not be reduced.

또한, 종래 기술의 경우 완충 부재(211)가 서포트 요크(201)의 끝단 및 스프링 수용부(213)의 내주면에 접할 뿐이어서 안정성이 떨어지는 문제점이 있었다.In addition, in the prior art, the buffer member 211 is in contact with the end of the support yoke 201 and the inner circumferential surface of the spring receiving portion 213, there is a problem that the stability is inferior.

따라서 본 발명은 위와 같은 문제점을 해결하기 위하여 발명된 것으로서, 서포트 요크의 결합홈에 삽입되는 결합돌기를 통해 서포트 요크에 장착되는 탄성 부재를 형성시킴으로써 서포트 요크의 축 방향 및 반경 방향의 진동 및 래틀 노이즈의 발생을 방지할 수 있는 조향장치를 제공하는 데 그 주된 목적이 있다.Therefore, the present invention was invented to solve the above problems, by forming an elastic member mounted to the support yoke through the engaging projection inserted into the coupling groove of the support yoke, vibration and rattle noise in the axial and radial directions of the support yoke. The main object is to provide a steering apparatus that can prevent the occurrence of the.
