자동차용 스티어링 칼럼의 틸팅장치용 액튜에이터의 치합력 조절장치{Gear controller of actuator for tilting apparatus of steering column for car}Gear controller of tilting apparatus of steering column for car

본 발명은 자동차용 스티어링 칼럼의 틸팅장치용 액튜에이터의 치합력 조절장치에 대한 것으로서, 더 상세하게는 틸팅용 동력을 제공하기 위한 액튜에이터와, 이 동력을 워엄기어에 전달하기 위한 워엄의 치합상태를 갠선한데 특징이 있는 것이다.The present invention relates to a device for adjusting the engagement force of the actuator for the tilting device of the steering column for a vehicle, and more particularly, an actuator for providing a power for tilting, and a state of engagement of a worm for transmitting this power to the worm gear. There is a characteristic.

일반적으로 자동차의 조향장치는 스티어링 샤프트의 상단에 핸들이 축착 고정되어 있는 바, 근래에는 이 핸들의 위치를 운전자의 신체조건에 맞게 위로 올리거나 밑으로 내릴 수 있도록 하기 위해 틸팅장치(T)를 설치하여 사용하고 있다.In general, steering devices of automobiles are fixedly fixed to the top of the steering shaft, and recently, a tilting device (T) is installed so that the position of the steering wheel can be raised or lowered according to the driver's physical condition. I use it.

그리고 이러한 틸팅장치는 스프링과 캠 등을 이용하여 인위적인 힘으로 작동시키는 수동식과, 틸팅용 액튜에이터(1)를 사용하여 작동시키는 전동식이 있다.And the tilting device is a manual type to operate by artificial force using a spring and a cam, etc., and there is an electric type to operate using the tilting actuator (1).

전동식은 도 1에서 보는 바와 같이 상측 칼럼(2)과 하측 칼럼(3)의 중단을 힌지점(4)으로 연결하고, 상기 힌지점(4)을 축으로 상측 칼럼(2)이 상, 하 회동될 수 있도록 하되, 도 2에서 보듯이 틸트용 액튜에이터(1)인 모터를 구동시켰을 때, 그 모터축에 마련된 워엄(11)이 하우징(16)속의 워엄기어(12)를 회전시키고, 워엄기어(12)가 다시 틸팅바(15)를 이동시켜 틸팅작동이 실시되도록 한 것이다.As shown in FIG. 1, the middle column of the upper column 2 and the lower column 3 are connected to the hinge point 4, and the upper column 2 is pivoted up and down with the hinge point 4 as the axis. 2, the worm 11 provided on the motor shaft rotates the worm gear 12 in the housing 16 and drives the worm gear (see FIG. 2). 12) is to move the tilting bar 15 again to perform the tilting operation.

그러나 이와 같은 종래의 틸팅용 액튜에이터(1)의 구조를 보면 축의 끝단에 형성된 워엄(11)과 하우징(16) 내부의 워엄기어(12)를 치합시켜 동력이 전달되도록 했을 때, 워엄(11)과 워엄기어(12)의 치합상태가 좋지 않으면 동력전달이 충분히 이루어지지 못할 뿐만 아니라 치합상태가 좋았다 하더라도 장기간 사용하여 마모가 발생하면 다시 치합상태가 나빠져 작동불량의 상태에 이르는 것은 물론 소음이 발생하여 상품가치를 떨어트리는 것이었다.However, in the structure of the conventional tilting actuator 1, when the worm 11 formed at the end of the shaft and the worm gear 12 inside the housing 16 are engaged with each other to transmit power, the worm 11 and If the worm gear 12 is not properly engaged, power transmission may not be sufficient, and even if the engagement condition is good, if the wear occurs after a long period of use, the engagement may worsen, resulting in a malfunction, and noise may occur. It was a loss of value.

따라서 본 발명은 상기와 같은 종래의 문제점을 감안하여 이를 해결 보완하고자 안출한 것으로서, 발명의 주된 목적은 틸팅용 액튜에이터의 워엄축을 워엄기어쪽으로 밀착시킬 수 있는 치합력 조절수단을 구비하여 평상시 항상 양호한 치합상태를 유지할 수 있도록 하고, 또 한편으로는 마모가 발생하여도 그 워엄 및 워엄기어에 의한 소음이 발생하지 않도록 하는데 있는 것이다.Therefore, the present invention has been made in view of the conventional problems as described above to solve the problem, the main object of the invention is always equipped with a fitting force adjustment means that can be in close contact with the worm gear side of the tilting actuator to the worm gear, always always good teeth. In order to maintain the state, and on the other hand, the noise of the worm and the worm gear does not occur even if wear occurs.

이를 위한 특징적인 실시 수단은 상측 칼럼과 하측 칼럼의 중단을 힌지점으로 연결하고, 상기 힌지점을 축으로 상측 칼럼이 상, 하 회동될 수 있도록 하기 위해 전동 액튜에이터를 사용한 자동차용 스티어링 칼럼의 틸팅장치에 있어서, 상기한 액튜에이터는 그 모터축의 중단에 워엄을 형성하여 하우징 내부의 워엄기어에 치합되도록 구성하되, 상기 하우징의 외측으로부터 나삽한 작은나사의 끝단면이 모터축의 끝단을 워엄기어 쪽으로 눌러줄 수 있도록 하는데 있다.A characteristic implementation means for this is a tilting device for a steering column for a vehicle using an electric actuator to connect the middle and lower columns of the upper column and the lower column to the hinge point, so that the upper column can be rotated up and down based on the hinge point. In the actuator, the actuator is configured to form a worm at the interruption of the motor shaft to be engaged with the worm gear inside the housing, and the end surface of the small screw inserted from the outside of the housing can press the end of the motor shaft toward the worm gear. To make it work.

이하 본 발명의 실시예에 따른 구성 및 작용을 첨부 도면에 따라 상세히 설명한다.Hereinafter, the configuration and operation according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1에서 보는 바와 같이 상측 칼럼(2)과 하측 칼럼(3)의 중단을 힌지점(4)으로 연결하고, 상기 힌지점(4)을 축으로 상측 칼럼(2)이 상, 하 회동될 수 있도록 하기 위해 전동 액튜에이터(1)를 사용하되, 상기한 액튜에이터(1)는 그 모터축의 중단에 워엄(11)을 형성하여 하우징(16) 내부의 워엄기어(12)에 치합되도록 구성하는 것은 종래와 대동소이하다.As shown in FIG. 1, the middle column of the upper column 2 and the lower column 3 may be connected to the hinge point 4, and the upper column 2 may be rotated up and down based on the hinge point 4. In order to ensure that the electric actuator (1) is used, the actuator (1) forms a worm (11) at the stop of the motor shaft and is configured to engage with the worm gear (12) inside the housing (16). It's quite the same.

본 발명에서는 도 3에서 보듯이 상기 하우징(16)의 외측으로부터 작은나사(5)를 나삽하여 그 끝단면이 모터축의 끝단(13) 부분을 워엄기어(12) 쪽으로 눌러 줄 수 있도록 하는데 특징이 있다.In the present invention, as shown in FIG. 3, the small screw 5 is inserted from the outside of the housing 16 so that its end surface can press the end portion 13 of the motor shaft toward the worm gear 12. .

도면중 미설명 부호 14는 워엄기어용 축이다.In the figure, reference numeral 14 denotes a worm gear shaft.

이와 같이 구성된 본 발명은 틸팅을 하기 위하여 사용자가 스위치를 조작하였을 때, 상기한 액튜에이터(1)가 구동하게 되고, 그에 따라서 상기 액튜에이터의 워엄(11)이 워엄기어(12)를 회전시키며, 워엄기어의 회전에 따라 틸팅바(15)의 위치를 이동시키기 때문에 틸팅작동이 이루어 지는 것이다.According to the present invention configured as described above, when the user operates the switch for tilting, the actuator 1 is driven, and accordingly, the worm 11 of the actuator rotates the worm gear 12 and the worm gear. The tilting operation is performed because the position of the tilting bar 15 is moved in accordance with the rotation of the.

이와 같이 틸팅작동을 실행함에 있어서, 워엄(11)과 워엄기어(12)의 치합상태가 불량하면 올바른 동력전달이 이루어지지 못하기 때문에 이때는 작은나사(5)를 돌려 모터축의 끝단(13)을 워엄기어(12)가 있는 쪽으로 밀어주면 워엄(11)이 워엄기어(12)와 양호한 상태로 밀착된다.In performing the tilting operation as described above, if the engagement state between the worm 11 and the worm gear 12 is poor, proper power transmission cannot be achieved. At this time, the small screw 5 is turned to secure the end 13 of the motor shaft. When the gear 12 is pushed toward the side, the worm 11 is in close contact with the worm gear 12 in a good state.

그리고 또 이와 같이 장기간 사용하여 치형이 마모되었을 경우, 다시 작은나사(5)를 더 조여주면 다시 양호한 밀착상태로 돌아갈 수 있게 되는 것이다.In addition, when the teeth are worn out in such a long time, by tightening the small screws (5) again, it is possible to return to a good close contact state again.

따라서 워엄(11)과 워엄기어(12)는 항상 유격이 없이 맞물린 상태로 회전하여 동력의 손실은 물론 소음 발생 없이 작동할 수 있게 되는 것이다.Therefore, the worm 11 and the worm gear 12 are always rotated in the engaged state without play without being able to operate without loss of power as well as noise.

위에서 상세히 설명한 바와 같은 본 발명은 작은나사(5)를 추가로 설치하여 액튜에이터의 모터축 끝단(13)을 워엄(11)쪽으로 밀어 워엄(11)과 워엄기어(12)의 치합상태를 항상 양호한 상태로 유지할 수 있기 때문에 틸팅작동이 유연하게 실시되고, 소음발생이 예방되는 등 여러 가지 장점을 갖는 것이다.In the present invention as described in detail above, by additionally installing a small screw (5) by pushing the motor shaft end 13 of the actuator toward the worm (11), the state of engagement between the worm 11 and the worm gear 12 is always in a good state Since the tilting operation can be performed flexibly, noise can be prevented, and so on, it has various advantages.
