본 발명은 모터의 작동에 의해 조향핸들을 틸팅할 수 있도록 한 자동차용 전동틸트컬럼에 관한 것으로서 특히 자동차의 틸팅시 스레드 너트와 기어스크류와의 유격을 보상하여 편마모 발생을 방지할 수 있도록 한 자동차용 전동틸트컬럼에 관한 것이다.The present invention relates to a motor-driven tilt column for tilting the steering wheel by the operation of the motor, and in particular for the car to compensate for the play between the thread nut and the gear screw during tilting of the car to prevent the occurrence of uneven wear It relates to an electric tilt column.

일반적으로 자동차의 틸트컬럼은 조향핸들과 고정되는 어퍼컬럼과, 기어박스와 고정되는 로워컬럼을 힌지로 원운동 가능하게 조립하되, 어퍼컬럼에는 스레드너트를 설치하고, 로워컬럼에는 모타를 설치하여 모터에 축설된 기어스크류를 상기 스레드너트와 치합고정한다.In general, the tilt column of the car is assembled by the steering column and the upper column fixed to the gear box and the lower column fixed to the hinge by the hinge, but the threaded nut is installed on the upper column and the motor is installed on the lower column. The gear screw built in the shaft is fixed to the thread nut.

그리고 상기와 같이 조립된 컬럼은 로워컬럼에 마운팅브라켓을 결합하여 차체에 고정한 상태로 자동차의 조향핸들을 힌지를 축으로 어퍼컬럼이 회전운동하게 하고, 스러트너트는 기어스크류에 의해 축방향으로 직선운동한다.The assembled column is coupled to the lower column by the mounting bracket, and the upper steering column rotates on the hinge of the steering wheel of the vehicle while the fixing bracket is fixed to the vehicle body. The nut is linearly moved in the axial direction by the gear screw. do.

이때 자동차의 조향핸들은 운전자의 체형과, 습관 등에 알맞게 조절코저할때, 모터를 작동시키면, 모터가 기어스크류를 회전시켜 스레드너트를 미로 당기는 작용에 의해 간편히 조절하는 것은 주지된 사실이다.At this time, it is well known that the steering wheel of the vehicle is easily adjusted by the action of pulling the thread nut by rotating the gear screw when the motor is operated when adjusting the body according to the driver's body shape and habit.

그러나, 종래의 전동틸트컬럼(51)의 틸트작동부(55)는 제 4 도 및 제 5 도에서와 같이 어퍼컬럼(52)과, 로워컬럼(53)을 힌지(54)에 의해 축설한 후 같이 상기 어퍼컬럼(52)에는 스레드너트(56)를 설치하고 로워컬럼(53)에는 모터(62)를 설치한 후 모터(62)에 축설된 기어스크류(63)는 상기 스레드너트(56)와 치합되게 결합하였다.However, the tilt operation unit 55 of the conventional electric tilt column 51 is arranged after the upper column 52 and the lower column 53 are hinged 54 as shown in FIGS. 4 and 5. Likewise, the upper column 52 has a thread nut 56 installed therein, and the lower column 53 has a motor 62 installed thereon, and the gear screw 63 installed at the motor 62 has the thread nut 56 at the same time. Joined tightly.

그리고 상기 스레드너트(56)이 상측으로 설치홈(57)을 가공하여 판스프링(58)과, 코일스프링(59)을 기어스크류(63)의 일측을 순차적으로 끼워 볼트(60)로 고정하여 유격을 보상하도록 하였다.In addition, the threaded nut 56 processes the mounting groove 57 upward, and the plate spring 58 and the coil spring 59 are sequentially inserted with one side of the gear screw 63 to be fixed by a bolt 60 to play therein. To compensate.

이와같은 종래의 전동틸트컬럼(51)은 모타(52)를 구동시켜 틸팅할시 어퍼컬럼(52)에 설치된 스레드너트(56)와, 로워컬럼(53)의 모터(52)에 축설된 기어스크류(53)의 습동시 설치홈(57)에 순차적으로 끼워 볼트(60)로 고정한 판스프링(58)이 코일스프링(59)의 스프링력에 의해 기어스크류(63)의 편측만을 잡아주므로 편마모와 발생되어 완벽한 유격을 잡아줄 수 없을 뿐 아니라, 노이즈(NOISE)가 발생되어 이유격이 조향핸들을 통해 운전자에게 느끼는 불쾌감까지 유발시키는 문제점이 야기되었다.Such a conventional electric tilt column 51 has a screw nut installed in the motor nut 52 of the lower column 53 and the thread nut 56 installed in the upper column 52 when the motor 52 is driven and tilted. Since the leaf spring 58, which is inserted into the installation groove 57 in the sliding motion of the 53 and fixed by the bolt 60, only holds one side of the gear screw 63 by the spring force of the coil spring 59, Not only was it not possible to catch the perfect play, but noise was generated, causing a problem that caused the discomfort to the driver through the steering wheel.

본 발명은 상기한 종래의 제문제점을 해결하하기 위하여 안출한 것으로서 본 발명의 목적으론 로워컬럼의 모터에 축설된 기어스크류의 치합되는 어퍼컬럼의 스레드너트 후단부 내측에 완충부시를 삽입한 상태로조임 스레드너트를 끼워 너트캡으로 고정하어 틸팅작동으로 인한 습동시 완충부시에 의해 습동마모를 최소화하려는 것과, 국부적인 힘이 가해지지 않도록 한 것이 그 특징이다.The present invention has been made in order to solve the above-mentioned conventional problems, for the purpose of the present invention in the state that the buffer bush is inserted into the rear end of the threaded nut of the upper column to be engaged with the gear screw installed in the motor of the lower column. The fastening thread nut is fixed with a nut cap to minimize sliding wear due to the cushioning bush during sliding due to the tilting operation, and to prevent local force from being applied.

제 1 도는 본 발명이 적용된 컬럼이 정면예시도를 나타낸 것이고, 제 2 도는 본 발명이 틸트작동부 조립단면도를 나타낸 것이며 제 3 도는 본 발명의 일측면도를 나타낸 것이다.Figure 1 shows a front view of the column to which the present invention is applied, Figure 2 shows a cross-sectional view of the tilt operation unit assembly of the present invention and Figure 3 shows one side view of the present invention.

제 1 도 내지 제 3 도에서와 같이 조향핸들과 고정되는 어퍼컬럼(2)과, 기어박스와 고정되는 로워컬럼(3)를 힌지(4)에 의해 축설한 후 틸트작동부(5)를 설치하여 전동틸트컬럼(1)을 형성하되, 상기 틸트작동부(5)의 스레드너트(6) 후방으론 완충부시(7)를 끼운 상태로, 조임스레드너트(8)를 적당한 힘을 가하여 조립한 후 후단면에 완충와셔(10)를 대로 너트캡(9)을 씌워 볼트(11)로 고정하여 사방을 콕킹하였다.As shown in FIGS. 1 to 3, the upper column 2 fixed to the steering wheel and the lower column 3 fixed to the gearbox are constructed by the hinge 4, and then the tilt operating part 5 is installed. After forming the electric tilt column (1), the threaded nut (6) of the tilt operating part 5 in the state in which the buffer bush (7) is inserted, the tightening thread nut (8) by applying a suitable force after assembly The buffer washer 10 was put on the rear end face, and the nut cap 9 was put on it to fix it with the bolt 11 and cocked in all directions.

그리고 로워컬럼(3)에 장착된 모터(12)의 기어스크류(13)를 상기 스레드너트(6)와, 조임스레드너트(8)를 체결된 상태로 하여 구성된 것이다.The screw nut 13 of the motor 12 mounted on the lower column 3 is configured such that the thread nut 6 and the tightening thread nut 8 are engaged with each other.

이와같이 구성된 전동스티어컬럼(1)의 틸트작동부(5)는 어퍼컬럼(2)에 설치된 스레드너트(6)의 후방으론 완충부시(7)를 요입하여 끼우고 조임스레드너트(8)를 적당한 힘으로 돌려가면서 삽입한다.The tilt actuating part 5 of the electric steering column 1 configured as described above inserts the buffer bush 7 into the rear of the threaded nut 6 installed on the upper column 2, and tightens the tightening thread nut 8 with a suitable force. Insert it while turning to.

그리고 스레드너트(6)의 후단면에는 기어스크류(13)의 회전시 조임스레드너트(8)가 빠지는 것을 방지하기 위하여 너트캡(9)를 씌워 고정하되, 너트캡(9) 내부측에 완충와셔(10)를 끼운 상태로 볼트(11)로 체결고정 한다.The nut nut 9 is fixed to the rear end of the thread nut 6 to prevent the tightening thread nut 8 from falling out when the gear screw 13 is rotated, and a buffer washer inside the nut cap 9. Fasten with bolt (11) while inserting (10).

한편, 상기 조임스레드너트(8)가 기어스크류(13)이 회전시 헛도는 것을 방지하기 위해 너트캡(9)이 원주면에 콕킹하여 고정한다.Meanwhile, the nut cap 9 is fixed to the circumferential surface by cocking the tightening thread nut 8 to prevent the screw screw 13 from rotating when rotating.

그리고, 로워컬럼(3)에 장착된 모터(12)의 기어스크류(13)는 상기 스레드너트(6)의 나사산과, 조임스레드너트(8)이 나사산과 치합된 상태로 결합하여 조립하는 것이다.In addition, the gear screw 13 of the motor 12 mounted on the lower column 3 is assembled by assembling the thread of the threaded nut 6 and the tightening threaded nut 8 in a state in which the threaded nut 8 is engaged with the thread.

이 상태에서 운전자가 전동 스티어링컬럼(1)이 로워컬럼(3)에서 어퍼컬럼(2)을 틸팅할시 틸트작동부(5)의 로워컬럼(3)에 설치된 모터(12)에 전기를 인가하여 구동시키면 이 모터(12)에는 축설된 기어스크류(13) 어퍼컬럼(2)에 창착된 스레드너트(6)와, 조임스레드너트(8)의 나사산을 따라 축방향으로 유동시켜 조향핸들이 회전방향으로 이동되게 하는 것이다.In this state, when the driver tilts the upper column 2 in the lower column 3, the driver applies electricity to the motor 12 installed in the lower column 3 of the tilt operating part 5. When driven, this motor 12 has a threaded nut 6 attached to the upper screw 2 of the gear screw 13 and a screw thread of the tightening threaded nut 8, and the steering wheel rotates in the axial direction. To be moved to.

이때, 상기 기어스크류(13)가 회전되면 전후회전방향에 따라 부시(7)의 탄성에 의해 스레드너트(6)와 조임스레드너트(8)는 기어스크류(13)의 내외측으로 밀어 유격을 보상하여 주는 것이다.At this time, when the gear screw 13 is rotated, the thread nut 6 and the tightening thread nut 8 are pushed in and out of the gear screw 13 by the elasticity of the bush 7 according to the front and rear rotation directions to compensate for the clearance. To give.

즉 회전방향이 전진일 경우에는 기어스크류(13)에서 스레드너트(6)와 조임스레드너트(8)가 완충부시(7)의 텐션력에 의해 양측으로 밀려 유격을 보상하여 주고, 후진일 경우에는 기어스크류(13)에서 스레드너트(6)와 조임스레드너트(8)가 완충부시(7)이 텐션력에 의해 내측으로 밀려 유격을 보상하여 기어스크류(13)가, 스레드너트(6)와 조임스레드너트(8)에서 습동시 완충부시(7)이 텐션력에 의해 습동시 강재와 강재가 접촉하여 생기는 마모를 최소로 하게 될 뿐만 아니라, 완충부시(7)가 전체적으로 지지하게 되므로서 국부적으로 힘이 가해지지 않도록, 너트캡(9)를 체결하는 볼트(11) 내측으로 완충와셔(10)에 의해 이중텐션력을 가해 국부적인 마모발생이 전혀 없게 되는 것이다.That is, when the direction of rotation is forward, the threaded nut 6 and the tightening threaded nut 8 in the gear screw 13 are pushed to both sides by the tension force of the buffer bush 7 to compensate for the clearance, and in the case of the reverse In the gear screw 13, the threaded nut 6 and the tightening threaded nut 8 are pushed inward by the cushioning bush 7 by the tension force to compensate for the clearance, so that the gear screw 13 is tightened with the threaded nut 6 In the threaded nut 8, the cushioning bush 7 during sliding is not only minimized abrasion caused by the contact between the steel and the steel sheet during the sliding due to the tension force, but also the buffer bush 7 is supported as a whole. In order to prevent this from being applied, a double tension force is applied by the buffer washer 10 to the inside of the bolt 11 to which the nut cap 9 is fastened so that no local wear occurs.

이상에서와 같이 틸트작동부의 스레드너트 후방으로 완충부시를 끼운상태로 조임스레드너트를 조립한후 후단면에 완충와셔를 대고 너트캡을 씌워 볼트로 고정하여 사방을 콕킹고정하므로서 기어스크류의 회전작동시 완충부시 및 완충와셔에 의해 스레드너트와 기어스크류간의 유격을 보상하여 편마모됨이 전혀 없게되는 효과가 있을 뿐 아니라 노이즈 발생이 전혀 없게 되는 효과가 있다.As described above, after assembling the tightening thread nut with the buffer bush inserted behind the threaded nut of the tilt operating part, put the buffer washer on the rear end and cover it with the nut cap and fix it with the bolt to fix the cocking all the way. The buffer bushing and the buffer washer compensate for the clearance between the threaded nut and the gear screw, so that there is no effect of uneven wear and no noise.
