Description

스티어링 칼럼용 베어링조립체{Bearing assembly for steering column}Bearing assembly for steering column}

본 발명은 스티어링 칼럼용 베어링조립체에 대한 것으로서, 더욱 상세하게는 핸들의 조타시 스티어링 칼럼의 회전정밀도 및 흔들림을 향상시킬 수 있는 스티어링 칼럼용 베어링조립체에 대한 것이다.The present invention relates to a bearing assembly for a steering column, and more particularly, to a steering column bearing assembly capable of improving rotational precision and shaking of the steering column when steering the steering wheel.

스티어링 칼럼은 핸들로 불리우는 스티어링휠과 차량 하부의 스티어링 기어를 연결하는 지지대이다. 이런 스티어링 칼럼은 도 5에 도시된 바와 같이 스티어링휠이 결합되는 어퍼 샤프트(1)와, 어퍼 샤프트(1)가 회전할 수 있게 베어링(2)으로 지지하여 어퍼 샤프트(1)를 감싸는 어퍼 파이프(5)와, 어펴 샤프트(1)의 회전력을 전달받어 스티어링 기어에 전달하는 로어 샤프트(3)와, 로어 샤프트(3)가 회전할 수 있게 베어링(2)으로 지지하여 로어 샤프트(3)를 감싸는 로어 파이프(7)를 구비한다.The steering column is a support connecting the steering wheel, called a steering wheel, to the steering gear under the vehicle. As shown in FIG. 5, the steering column includes an upper shaft 1 to which the steering wheel is coupled, and an upper pipe surrounding the upper shaft 1 by supporting it with a bearing 2 so that the upper shaft 1 can rotate ( 5) and the lower shaft 3 which transmits the rotational force of the shaft 1 to the steering gear and the bearing shaft 2 so that the lower shaft 3 can rotate to surround the lower shaft 3 The lower pipe 7 is provided.

어퍼 샤프트(1)가 회전하면 어퍼 샤프트(1)의 회전력을 로어 샤프트(3)로 전달되도록 로어 샤프트(3)는 어퍼 샤프트(1)에 삽입되어 결합된다. 이때 샤프트(1, 3)가 회전하면 어퍼 샤프트(1)와 로어 샤프트(3)의 결합부가 처지거나 흔들려서 조타시 회전 정밀도가 낮아진다. 그래서 이를 방지하기 위하여 샤프트(1, 3)가 파이프(5, 7)에 지지되도록 베어링조립체(8)가 장착된다.When the upper shaft 1 rotates, the lower shaft 3 is inserted into and coupled to the upper shaft 1 so that the rotational force of the upper shaft 1 is transmitted to the lower shaft 3. At this time, when the shafts 1 and 3 rotate, the coupling portion of the upper shaft 1 and the lower shaft 3 sags or shakes, resulting in low rotational accuracy during steering. So, to prevent this, the bearing assembly 8 is mounted so that the shafts 1 and 3 are supported by the pipes 5 and 7.

공개특허 제10-2014-0011927호(공개일자 2014년 01월 29일)Patent Publication No. 10-2014-0011927 (published on January 29, 2014) 공개특허 제10-2014-0126670호(공개일자 2014년 10월 31일)Patent Publication No. 10-2014-0126670 (published on October 31, 2014) 공개특허 제10-2015-0005456호(공개일자 2015년 01월 14일)Patent Publication No. 10-2015-0005456 (published on January 14, 2015) 등록특허 제10-1827913호(등록일자 2018년 02월 05일)Registered Patent No. 10-1827913 (Registration Date February 05, 2018)

종래의 스티어링 칼럼용 베어링조립체(8)는 스틸로 된 볼베어링으로만 구성된다. 이 경우에는 어퍼샤프트(1) 및 로어 샤프트(3)의 양단에서 지지되는 베어링(2)과 중심을 일치시키기 위해서는 볼베어링의 정밀도가 높아야 한다. 그래서 볼베어링의 회전 정밀도가 떨어질 경우에는 동심도를 맞추기가 어렵다는 문제점이 있었다.The conventional bearing assembly for a steering column (8) consists only of a ball bearing made of steel. In this case, in order to match the center of the bearing 2 supported at both ends of the upper shaft 1 and the lower shaft 3, the precision of the ball bearing must be high. Therefore, when the rotational accuracy of the ball bearing is poor, there is a problem that it is difficult to match the concentricity.

본 발명은 상기의 문제점을 해결하기 위한 것이다. 본 발명은 스티어링 칼럼 샤트트의 회전시 정말도를 향상시키고 떨림을 보완할 수 있는 스티어링 칼럼용 베어링조립체를 제공하는 것을 목적으로 한다.The present invention is to solve the above problems. An object of the present invention is to provide a bearing assembly for a steering column that can improve the degree of realism and compensate for shaking when the steering column chart is rotated.

본 발명에 따른 스티어링 칼럼용 베어링조립체는 베어링과, 이너 몰드와, 아우터 몰드를 포함한다. 상기 베어링은 내륜과, 외륜과, 볼과, 리테이너를 구비한다. 상기 이너 몰드는 스티어링 칼럼의 샤프트가 삽입되며, 상기 내륜을 감싸도록 결합된 합성수지로 형성된다. 상기 아우터 몰드는 상기 스티어링 칼럼의 파이프에 삽입되며 상기 외륜을 감싸도록 결합된 몸체부와, 상기 파이프의 내부를 지지하도록 상기 몸체부의 일단에서 축방향으로 연장된 제1지지부와, 상기 파이프의 내부를 지지하도록 상기 몸체부의 타단에서 축방향으로 연장된 제2지지부를 구비하며, 합성수지로 형성된다.The bearing assembly for a steering column according to the present invention includes a bearing, an inner mold, and an outer mold. The bearing has an inner ring, an outer ring, a ball, and a retainer. The inner mold is a shaft of the steering column is inserted, it is formed of a synthetic resin coupled to surround the inner ring. The outer mold is inserted into a pipe of the steering column, and a body part coupled to surround the outer ring, a first support part axially extending from one end of the body part to support the inside of the pipe, and the inside of the pipe It has a second support portion extending in the axial direction from the other end of the body portion to support, it is formed of a synthetic resin.

또한, 상기의 스티어링 칼럼용 베어링조립체에 있어서, 상기 제1지지부는 외경이 상기 파이프의 내경보다 더 크며, 상기 파이프에 삽입될 수 있게 수축될 수 있도록 원주방향을 따라 복수 개로 절개되는 것이 바람직하다. 이 경우 상기 제2지지부는 외경이 상기 파이프의 내경보다 더 작으며, 상기 제1지지부의 직경이 수축되면 상기 파이프의 내경을 지지할 수 있게 벌어질 수 있도록 상기 몸체부에서 복수 개가 연장된다.In addition, in the bearing assembly for the steering column, the first support portion is larger than the inner diameter of the pipe, and is preferably cut in plural along the circumferential direction so as to be able to be shrunk to be inserted into the pipe. In this case, the second supporting portion has an outer diameter smaller than the inner diameter of the pipe, and when the diameter of the first supporting portion is contracted, a plurality of pieces are extended from the body portion so that it can be opened to support the inner diameter of the pipe.

또한, 상기의 스티어링 칼럼용 베어링조립체에 있어서, 상기 제2지지부는 상기 외륜을 축방향으로 구속시키도록 반경방향으로 돌출된 구속돌기가 형성된 것이 바람직하다.In addition, in the bearing assembly for a steering column, it is preferable that the second support portion is formed with a locking projection protruding in the radial direction to constrain the outer ring in the axial direction.

본 발명에 의하면, 베어링조립체가 축방향으로 변형될 수 있는 아우터 몰드를 구비함으로 인하여 어퍼 샤프트와 로어 샤프트의 동심도를 맞추기가 용이하다.According to the present invention, it is easy to match the concentricity of the upper shaft and the lower shaft because the bearing assembly has an outer mold that can be deformed in the axial direction.

또한, 본 발명에 의하면 아우터 몰드의 축방향으로 양단에서 파이프를 지지하므로 샤프트의 처짐 및 흔들림을 감소시킬 수 있어서, 스티어링 휠의 조타시 회전 정밀도를 높일 수 있다.In addition, according to the present invention, since the pipes are supported at both ends in the axial direction of the outer mold, sag and shaking of the shaft can be reduced, so that the rotation precision during steering of the steering wheel can be increased.

도 1 내지 도 5를 참조하여 본 발명에 따른 스티어링 칼럼용 베어링조립체의 일 실시예를 설명한다.An embodiment of a bearing assembly for a steering column according to the present invention will be described with reference to FIGS. 1 to 5.

본 발명에 따른 베어링조립체(A)는 베어링(10)과, 이너 몰드(15)와, 아우터 몰드(20)를 포함한다.The bearing assembly (A) according to the present invention includes a bearing 10, an inner mold 15, and an outer mold 20.

베어링(10)은 내륜(11)과, 외륜(12)과, 볼(13) 및 리테이너(14)를 구비한다. 베어링(10)은 널리 알려진 볼베어링과 동일하므로 자세한 설명은 생략한다.The bearing 10 includes an inner ring 11, an outer ring 12, a ball 13 and a retainer 14. Since the bearing 10 is the same as the well-known ball bearing, detailed description is omitted.

이너 몰드(15)는 합성수지로 형성되며, 스티어링 칼럼의 어퍼 샤프트(1)가 삽입되어 지지되고 베어링(10)의 내륜(11)을 감싸도록 결합된다.The inner mold 15 is formed of synthetic resin, and the upper shaft 1 of the steering column is inserted and supported, and is coupled to surround the inner ring 11 of the bearing 10.

아우터 몰드(20)는 합성수지로 형성되며 몸체부(21)와, 제1지지부(23) 및 제2지지부(25)를 구비한다. 몸체부(21)는 베어링(10)의 외륜을 감싸도록 결합되며 어퍼 파이프(5)에 삽입된다. 이때 몸체부(21)의 외경은 어퍼 파이프(5)의 내경보다 약간 작게 형성된다. 그래서 어퍼 파이프(5)의 내부에 용이하게 삽입될 수 있다.The outer mold 20 is formed of a synthetic resin and includes a body portion 21, a first support portion 23 and a second support portion 25. The body portion 21 is coupled to surround the outer ring of the bearing 10 and is inserted into the upper pipe 5. At this time, the outer diameter of the body portion 21 is formed slightly smaller than the inner diameter of the upper pipe (5). Thus, it can be easily inserted into the upper pipe 5.

제1지지부(23)는 어퍼 파이프(5)의 내부를 지지하도록 몸체부(21)의 일단에서 축방향으로 연장된다. 제1지지부(23)가 어퍼 파이프(5)의 내부를 지지하므로 외경이 어퍼 파이프(5)의 내경보다 더 크게 형성된다. 그리고 제1지지부(23)는 어퍼 파이프(5)에 삽입될 수 있도록 반경방향으로 수축할 수 있게 원주방향을 따라 복수 개로 절개된다.The first support portion 23 extends axially from one end of the body portion 21 to support the interior of the upper pipe 5. Since the first support part 23 supports the inside of the upper pipe 5, the outer diameter is formed larger than the inner diameter of the upper pipe 5. And the first support portion 23 is cut in plural along the circumferential direction so that it can contract in the radial direction so that it can be inserted into the upper pipe (5).

제2지지부(23)는 몸체부(21)의 타단에서 축방향으로 연장된다. 이때 제2지지부(23)는 어퍼 파이프(5)에 용이하게 삽입될 수 있도록 외경이 어퍼 파이프(5)의 내경보다 작게 형성된다. 그러나 제1지지부(23)가 반경방향으로 수축하면 어퍼 파이프(5)를 지지할 수 있게 반경방향으로 벌어질 수 있도록 몸체부(21)에서 원주방향으로 일정 간격 이격하도록 축방향으로 복수 개가 연장된다. 따라서 아우터 몰드(20)는 어퍼 파이프(5)에 삽입되기 전에서는 제2지지부(25)의 외경이 어퍼 파이프(5)의 내경보다 작지만 아우터 몰드(20)가 어퍼 파이프(5)에 삽입되면 제1지지부(23)가 반경방향으로 수축하여 제2지지부(25)를 반경방향으로 벌린다. 그래서 제2지지부(25)가 어퍼 파이프(5)의 내경을 지지하게 된다. 그리고 제2지지부(25)는 베어링(10)의 외륜(12)을 구속시키도록 내측에서 반경방향으로 돌출된 구속돌기(26)가 형성된다. 따라서 베어링(10)은 아우터 몰드(20)에서 분리되지 않는다.The second support portion 23 extends in the axial direction from the other end of the body portion 21. At this time, the second support portion 23 is formed to have an outer diameter smaller than the inner diameter of the upper pipe 5 so that it can be easily inserted into the upper pipe 5. However, when the first supporting portion 23 contracts in the radial direction, a plurality of axially extends so as to be spaced apart in the circumferential direction from the body portion 21 so as to be radially opened to support the upper pipe 5 . Therefore, before the outer mold 20 is inserted into the upper pipe 5, the outer diameter of the second support portion 25 is smaller than the inner diameter of the upper pipe 5, but the outer mold 20 is inserted into the upper pipe 5. The first support portion 23 contracts in the radial direction to spread the second support portion 25 in the radial direction. Thus, the second support portion 25 supports the inner diameter of the upper pipe 5. And the second support portion 25 is formed with a locking projection 26 that protrudes radially from the inside to constrain the outer ring 12 of the bearing 10. Therefore, the bearing 10 is not separated from the outer mold 20.

본 실시예의 베어링조립체가 스틸로 된 베어링으로만 구성될 경우 베어링의 정밀도가 높지 않을 경우에는 어퍼 샤프트(1)와 로어 샤프트(3)가 어긋나게 되어 회전 정밀도를 높이기가 어렵다. 본 실시예의 경우 아우터 몰드(20)가 합성수지로 형성되어 반경 방향으로 변형이 가능하므로 어퍼 샤프트(1) 및 로어 샤프트(3)의 동심을 맞출 수 있다.When the bearing assembly of the present embodiment is composed of only a bearing made of steel, when the precision of the bearing is not high, the upper shaft 1 and the lower shaft 3 are misaligned, making it difficult to increase rotation accuracy. In the case of this embodiment, since the outer mold 20 is formed of synthetic resin and can be deformed in the radial direction, the upper shaft 1 and the lower shaft 3 can be concentric.

또한, 본 실시예의 경우 몸체부(21) 및 제2지지부(25)가 어퍼 파이프(5)의 외경 보다 작은 치수로 형성된다. 그래서 조립시 용이하게 어퍼 파이프(5)의 내부에 삽입시킬 수 있다. 한편 본 실시예의 베어링조립체(A)가 어퍼 파이프(5) 내부에 조립되면 제1지지부(23)가 어퍼 파이프(5)를 지지하는 한편 반경방향으로 수축된다. 그러면 제2지지부(23)가 반경방향으로 벌려져서 어퍼 파이프(5)를 지지한다. 즉 본 실시예의 아우터 몰드(20)는 축방향으로 일단 및 타단의 양단이 모두 어퍼 파이프(5)의 내부를 지지한다. 따라서 샤프트(1, 3)의 처짐을 감소시킬 수 있을 뿐만 아니라 회전시 샤프트의 흔들림을 감소시킬 수 있다.In addition, in the case of this embodiment, the body portion 21 and the second support portion 25 are formed with dimensions smaller than the outer diameter of the upper pipe 5. Therefore, it can be easily inserted into the upper pipe 5 during assembly. On the other hand, when the bearing assembly A of this embodiment is assembled inside the upper pipe 5, the first support portion 23 supports the upper pipe 5 and contracts in the radial direction. Then, the second support part 23 is opened in the radial direction to support the upper pipe 5. That is, in the outer mold 20 of this embodiment, both ends of one end and the other end in the axial direction support the inside of the upper pipe 5. Therefore, it is possible to reduce the deflection of the shafts 1 and 3 as well as to reduce the shaking of the shaft during rotation.
