Description

  The present invention relates to a vehicle steering apparatus. In particular, the present invention relates to a vehicle steering apparatus that can adjust the inclination angle of the steering shaft and / or the axial position of the steering shaft in accordance with the driving posture of the driver.

  As a vehicle steering apparatus, there is a tilt / telescopic type steering apparatus that can adjust the tilt angle of the steering wheel and adjust the axial position of the steering wheel according to the driving posture of the driver.

  For example, in a tilt / telescopic steering device disclosed in Japanese Patent Application Laid-Open No. 11-278283, an upper inner column is slidably inserted and fitted into a lower outer column. A distance bracket having a telescopic adjustment groove is attached to the inner column on the upper side, and the distance bracket is configured to be in sliding contact with the inner side of the vehicle body side bracket having the tilt adjustment groove. A fastening bolt is inserted through the telescopic adjustment groove and the tilt adjustment groove, and an operation lever is attached to one end of the fastening bolt.

  As a result, when the operating lever is swung, the tightening bolt moves in the axial direction to release the tightening of the vehicle body side bracket and the distance bracket, and the tightening bolt moves in the vertical direction along the tilt adjustment groove. The inclination angle of the inner column on the upper side can be adjusted, and the inner column can be moved in the axial direction along the telescopic adjustment groove of the distance bracket to adjust the axial position.

  After tilting and telescopic adjustment, if the control lever is swung in the opposite direction, the tightening bolt moves in the axial direction and presses the body side bracket against the distance bracket, thereby tilting and telescopic the upper inner column. It can be tightened after adjustment. In this way, both tilt adjustment and telescopic adjustment can be performed by swinging one operation lever.

  In the tilt / telescopic steering device disclosed in the above publication, the inner column on the upper side is slidably fitted to the outer column on the lower side to increase the rigidity of both columns.

  However, since the upper inner column is not necessarily clamped directly to the lower outer column, a bending load is applied to the steering wheel (that is, the steering wheel is squeezed vertically). The inner column on the upper side sometimes moves so as to swing slightly, and the rigidity of both columns was not necessarily high.

  Although it is conceivable to increase the rigidity by providing a plurality of reinforcing plates on the distance bracket provided on the inner column on the upper side, there is a risk that the increase in the number of parts may cause an increase in manufacturing cost. .

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a vehicle steering apparatus in which the tilt and / or telescopic position of the steering column can be adjusted to be extremely high.

In order to achieve the above object, a vehicle steering apparatus according to the invention of claim 1 includes:
An inner column that rotatably supports one end side of the steering shaft;
An outer column that rotatably supports the other end side of the steering shaft and slidably fits the inner column;
A pair of clamp members formed integrally with the outer column, each having a holding surface for holding the inner column;
A clamping means for moving the pair of clamp members so as to be close to each other and clamping and holding the inner column with the pair of clamp members;
Accordingly, it is possible to adjust the telescopic position of the steering shaft by releasing the tightening of the tightening means and moving the steering shaft in the axial direction.

The invention according to claim 2 for achieving the above object is the vehicle steering apparatus according to claim 1,
The outer column is rotatably supported by the vehicle body, and the tilt position of the steering shaft can be adjusted when releasing the tightening means.

Furthermore, a vehicle steering apparatus according to the invention of claim 3 for achieving the above object is provided.
An inner column that rotatably supports one end side of the steering shaft;
An outer column that rotatably supports the other end side of the steering shaft and that is slidably fitted to the inner column and is rotatably supported on the vehicle body side;
A pair of clamp members formed integrally with the outer column, each having a holding surface for holding the inner column;
A clamping means for moving the pair of clamp members so as to be close to each other and clamping and holding the inner column by the pair of clamp members;
Thus, the tilting position of the steering shaft can be adjusted by releasing the tightening of the tightening means.

Furthermore, a vehicle steering apparatus according to the invention of claim 4 for achieving the above object is provided.
An inner column that rotatably supports one end side of the steering shaft;
An outer column that rotatably supports the other end side of the steering shaft and slidably fits the inner column;
A pair of clamp members disposed on the outer periphery of the outer column, each having a holding surface for holding the outer column;
A clamping means for moving the pair of clamp members so as to be close to each other and clamping the outer column directly to the inner column by the pair of clamp members;
Thus, the tightening means is released, the steering shaft is moved in the axial direction, and the telescopic position of the steering shaft can be adjusted.

  Thus, in the vehicle steering device according to the invention described in each claim of the present application, since the inner column is configured to be directly clamped by the outer column, a bending load acts on the steering wheel. Even when the steering wheel is twisted in the vertical direction, the inner column does not move so as to swing slightly, and the rigidity of both columns can be remarkably increased.
