The present invention relates to a telescope steering apparatus having a teles second gear and a teles first gear. More particularly, the present invention relates to a telescope steering device for securing a fixed structure in the teles direction between an outer tube and an inner tube.

Recently, as the competition in the automobile market is intensifying and the demands of consumers are diversified, the desire for more driver-oriented intelligent cars is increasing. One of these trends is that the driver can easily hold the steering wheel and drive comfortably. The mounting of tilt-and-telescope steering systems using drive motors to adjust the relative position of the steering wheel relative to is increasing.

Here, the tilt and telescope steering system means adjusting the position of a steering wheel used in a passenger car, and the adjustment of the position of the steering device includes a tilt motion and a telescope motion.

First, the tilting operation adjusts the fixed angle of the steering wheel up and down according to the driver's position seated in the driver's seat, and the telescope operation adjusts the distance between the steering wheel and the driver by stretching the length of the steering column to fit the driver's body shape. It is.

1 is a schematic diagram of a conventional telescope steering apparatus.

As shown, the telescope steering device includes an outer tube 100 for receiving a steering shaft 175, an inner tube 170 introduced into the outer tube 100, and a lower bracket fixed to the vehicle together with the inner tube 170. 165, the support part 155 fixed to the lower part of the outer tube 100 and both wings are directed to the lower side, the upper bracket 105 and the upper bracket 105 fixed to the vehicle body together with the outer tube 100. The support bracket 150 is formed to be in contact with the outer surface of both wings of the support portion 155, the tilt long hole 110 is formed, the adjustment bolt 130 through the tilt long hole 110, the support bracket 150 It is configured to include a tilt first gear 145 and the tilt second gear 140, which is coupled to or separated from the tilt first gear 145 provided on one side.

Once the adjustment lever 115 is released, the tilt second gear 140 is separated from the tilt first gear 145 by the cam 135, and the adhesion between the support bracket 150 and the support 155 is removed. Therefore, the outer tube 100 and the support 155 can be moved in the teles direction and the tilt direction.

In addition, when the adjustment lever 115 is locked, the tilt first gear 145 and the tilt second gear 140 are closely attached to each other, and the support bracket 150 and the support 155 are tightly fixed. Thus, the outer tube 100 is fixed in the teles direction and the tilt direction.

However, even when the control lever 115 is locked, there is a problem that the contact between the support 155 and the support bracket 150 is released or loosened when the shock is received due to a collision or the like.

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a telescope steering apparatus having a teles second gear and a teles first gear for securing a fixed structure in the teles direction between an outer tube and an inner tube in a telescope steering apparatus. To provide that purpose.

In order to achieve the above object, the present invention provides a telescope steering apparatus, comprising: a teles first gear having a gear tooth fixed to a support part; A second telescopic gear formed with a gear tooth and engaged or separated from the first telescopic gear and fixed in a telescopic direction; An adjusting bolt penetrating the teles first gear and the teles second gear; An elastic body provided between the teles first gear and the teles second gear; And it is provided on one side of the adjustment bolt provides a telescope steering device comprising a control lever for rotating the adjustment bolt.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings.
