본 발명은 차량용 조향장치의 기어박스에 관한 것으로서, 보다 상세하게는 실린더튜브의 변형이 방지됨은 물론 강성을 유지함으로써 파손을 예방하여 누유를 방지할 수 있도록 한 차량용 조향장치의 기어박스에 관한 것이다.The present invention relates to a gearbox of a vehicle steering apparatus, and more particularly, to a gearbox of a vehicle steering apparatus that prevents deformation by preventing rigidity and prevents leakage by maintaining rigidity.

일반적으로 조향장치는 차량의 진행방향을 바꾸기 위한 것으로, 운전석에 설치되는 조향 휠과, 그 하측에 구비되는 조향축, 그리고 이 조향축과 연결되어 동력전달방향을 전환하는 기어박스 등으로 이루어져 있다.In general, a steering apparatus is used to change a traveling direction of a vehicle, and includes a steering wheel installed in a driver's seat, a steering shaft provided at a lower side thereof, and a gear box connected to the steering shaft to switch a power transmission direction.

특히, 상기 기어박스는, 조향축으로부터 조향 휠의 회전력을 전달받게 되는 피니언과 이 피니언에 치합되어 피니언의 회전운동을 직선운동으로 변환하게 되는 랙 샤프트를 요체로 하고 있다.In particular, the gearbox includes a pinion which receives the rotational force of the steering wheel from the steering shaft and a rack shaft which is engaged with the pinion and converts the rotational motion of the pinion into linear motion.

도 4에는 종래 기어박스 어셈블리의 통상적인 예가 도시되어 있는데, 상기 피니언(10)은 피니언 하우징(11)에 수용되고, 랙 샤프트(20)는 중공의 실린더튜브(21)에 수용된 상태에서, 피니언 하우징(11)과 실린더튜브(21)가 서로 결합되어 있음을 알 수 있다.A typical example of a conventional gearbox assembly is shown in FIG. 4, with the pinion 10 housed in the pinion housing 11 and the rack shaft 20 housed in the hollow cylinder tube 21. It can be seen that 11 and the cylinder tube 21 are coupled to each other.

또, 실린더튜브(21)에 수용된 랙 샤프트(20)의 말단부 즉, 랙 엔드(20a)는 벨로우즈 구조로 된 부트(30)에 수용되면서 타이로드 엔드(40)와 연결되어 있다.In addition, the distal end of the rack shaft 20 accommodated in the cylinder tube 21, that is, the rack end 20a is connected to the tie rod end 40 while being accommodated in the boot 30 having a bellows structure.

이와 같은 구성을 갖고 있는 차량용 조향장치의 기어박스 어셈블리는, 도면에도 나타나 있듯이, 피니언 하우징(11) 부위에 구비되는 브라켓(50)과, 실린더튜브(21) 부위에 구비되는 또하나의 브라켓(60;이하, 앞서의 브라켓과 구분하여 '클램프'라 함)에 의해 차체의 하측에 마운팅되며, 이렇게 고정된 기어박스 어셈블리 는 그 하측에 조립되는 로어 플레이트(미도시)에 의해 은폐된다.As shown in the drawing, the gearbox assembly of the vehicle steering apparatus having such a configuration includes a bracket 50 provided at the pinion housing 11 and another bracket 60 provided at the cylinder tube 21. ; Hereafter, it is mounted to the lower side of the vehicle body by the 'clamp' to distinguish from the above bracket, the gearbox assembly fixed in this way is concealed by a lower plate (not shown) assembled to the lower side.

이하에서는 본 발명에 따른 차량용 조향장치의 기어박스에 대한 바람직한 실시예를 첨부도면에 의거하여 상세히 설명한다.Hereinafter, a preferred embodiment of a gearbox of a vehicle steering apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 기어박스의 실린더튜브가 마운팅브라켓과 조립되는 상태를 설명하는 부분사시도이고, 도 2는 도 1의 조립상태 정면도이며, 도 3은 도 2의 A - A선 단면도로서, 종래 기술을 도시한 도 4 내지 도 6과 동일한 부위에 대해서는 동일한 참조부호를 부여하며 그 상세한 설명은 생략한다.1 is a partial perspective view illustrating a state in which a cylinder tube of a gearbox according to the present invention is assembled with a mounting bracket, FIG. 2 is a front view of the assembled state of FIG. 1, and FIG. 3 is a cross-sectional view taken along a line A-A of FIG. The same parts as in Figs. 4 to 6 showing the prior art are denoted by the same reference numerals and the detailed description thereof will be omitted.

도 4에 나타나 있는 바와 같이, 상기 피니언(10)은 피니언 하우징(11)에 수용되고, 랙 샤프트(20)는 중공의 실린더튜브(21)에 수용된 상태에서, 피니언 하우징(11)과 실린더튜브(21)가 서로 결합되어 있음을 알 수 있다.As shown in FIG. 4, the pinion 10 is accommodated in the pinion housing 11 and the rack shaft 20 is accommodated in the hollow cylinder tube 21. The pinion housing 11 and the cylinder tube ( It can be seen that 21) is combined with each other.

또, 실린더튜브(21)에 수용된 랙 샤프트(20)의 말단부 즉, 랙 엔드(20a)는 벨로우즈 구조로 된 부트(30)에 수용되면서 타이로드 엔드(40)와 연결되어 있다.In addition, the distal end of the rack shaft 20 accommodated in the cylinder tube 21, that is, the rack end 20a is connected to the tie rod end 40 while being accommodated in the boot 30 having a bellows structure.

이와 같은 구성을 갖고 있는 차량용 조향장치의 기어박스 어셈블리는, 도 4에도 나타나 있듯이, 피니언 하우징(11) 부위에 구비되는 브라켓(50)과, 실린더튜브(21) 부위에 구비되는 또하나의 브라켓(100;이하, 앞서의 브라켓과 구분하여 '클램프'라 함)에 의해 차체의 하측에 마운팅되며, 이렇게 고정된 기어박스 어셈블리는 그 하측에 조립되는 로어 플레이트(미도시)에 의해 은폐된다.As shown in FIG. 4, the gearbox assembly of the vehicle steering apparatus having such a configuration includes a bracket 50 provided at the pinion housing 11 and another bracket provided at the cylinder tube 21. 100; hereinafter, it is mounted to the lower side of the vehicle body by the "clamp" as distinguished from the above bracket, the fixed gearbox assembly is concealed by a lower plate (not shown) assembled to the lower side.

한편, 상기 클램프(100)는 실린더튜브(21)의 외주에 감싸이도록 끼워진 마운팅브라켓(110)과, 이 마운팅브라켓(110)의 단부에 고정된 원통형의 부시클램프(120)로 이루어지고, 상기 부시클램프(120)에는 부시(130)가 끼워져 고정된 구조로 되어 있다. 또 상기 부시(130)는 내측에 부설된 스틸재의 파이프(131)와, 이 파이프를 감싸도록 부설되되 고무재질로 된 부시(132)로 이루어져 있다.On the other hand, the clamp 100 is made of a mounting bracket 110 is fitted to be wrapped around the outer periphery of the cylinder tube 21, a cylindrical bush clamp 120 fixed to the end of the mounting bracket 110, the bush The clamp 120 has a structure in which the bush 130 is fitted and fixed. In addition, the bush 130 is made of a steel pipe 131, which is placed on the inside, and is placed to surround the pipe, but consists of a bush 132 of rubber material.

본 발명의 요부에 해당하는 상기 클램프(100)에 의한 마운팅 구조를 보다 상세히 살펴보면, 마운팅브라켓과 접촉하는 실린더튜브의 외주에는 소정의 폭으로 너어링면(21a)이 형성되어 마운팅브라켓(110)을 실린더튜브의 축방향으로 끼운후 상기 너어링면에서 압입하여 결합되고, 상기 실린더튜브(21)에는 일정한 간격을 두고 환형의 요홈(21b)이 형성되며, 이 요홈(21b)에 끼워져 마운팅브라켓(110)이 실린더튜브의 축방향으로 이동하지 않도록 멈춤링(21c)이 구비된다. 본 발명의 실시예에서는 멈춤링이 C형 클립이 사용된 상태를 도 1에 도시하고 있다. Looking at the mounting structure by the clamp 100 corresponding to the main part of the present invention in more detail, the outer surface of the cylinder tube in contact with the mounting bracket is formed on the outer surface of the mounting bracket 110 with a predetermined width to the mounting bracket 110 After fitting in the axial direction of the cylinder tube is press-fitted in the kneading surface and coupled, the cylinder tube 21 is formed with an annular groove 21b at regular intervals, it is fitted in the groove 21b and mounting bracket 110 ) Is provided with a stop ring (21c) does not move in the axial direction of the cylinder tube. In the embodiment of the present invention is shown a state in which the stop ring is a C-type clip is used in FIG.

따라서 상기 실린더튜브(21)와 마운팅브라켓(110)을 고정하기 위해 용접을 하지 않고 너어링면(21a)으로 마운팅브라켓(110)을 압입하여 고정하기 때문에 용접부의 파손 및 변형이 발생하지 않음은 물론이고, 또 상기 멈춤링(21c)에 의해 마운팅브라켓(110)의 축방향 이동을 제한하여 조립력이 향상된다.Therefore, since the mounting bracket 110 is press-fitted and fixed to the knurling surface 21a without welding in order to fix the cylinder tube 21 and the mounting bracket 110, the breakage and deformation of the welded portion are not generated. In addition, the assembly ring is improved by limiting the axial movement of the mounting bracket 110 by the stop ring (21c).

이상에서 설명한 바와 같이 본 발명에 의하면, 마운팅브라켓과 접촉하는 실린더튜브의 외주에 너어링면이 형성되어 마운팅브라켓을 압입하여 고정함으로써 실린더튜브에 마운팅브라켓을 설치할 때 실린더튜브의 변형이 방지됨은 물론 조립강성을 유지함으로써 파손을 예방하고 누유를 방지할 수 있는 효과가 있다.As described above, according to the present invention, a knurling surface is formed on the outer circumference of the cylinder tube in contact with the mounting bracket, and the deformation of the cylinder tube is prevented when the mounting bracket is installed in the cylinder tube by pressing and fixing the mounting bracket. Maintaining rigidity prevents breakage and prevents leakage.

또한 상기 실린더튜브에는 환형의 요홈이 일정한 간격을 두고 형성되고, 이 요홈에는 C형 클립형태의 멈춤링이 설치되어 마운팅브라켓이 실린더튜브의 축방향으로 이동하지 않도록 견고하게 설치할 수 있게 되는 효과가 있다.In addition, the cylinder tube has an annular groove formed at regular intervals, and this groove is provided with a C-type stop ring to firmly install the mounting bracket so that it does not move in the axial direction of the cylinder tube. .
