no. 1 Embodiment approach

[0237] Reference Figure 1~5 The first embodiment of the present invention will be described. The vehicle steering system of this embodiment can adjust the steering wheel 1 (refer to Figure 52 The front and rear positions and the up and down positions of) include a steering column 6a, a steering shaft 5a, a support bracket 18a, a spacer bracket 17a, a clamping mechanism 29 including an adjustment rod 24a and the like.

[0238] The steering column 6a is fitted on the inner diameter side of the rear portion of the outer column 13a arranged on the front side (lower side) by fitting the front portion of the inner column 14a arranged on the rear side (upper side) relatively displaceable in the axial direction, Therefore, it is configured to expand and contract over the entire length.

[0239] The outer columns 13a are manufactured by die-casting light alloys such as aluminum-based alloys and magnesium-based alloys, and are respectively integrally installed in the gear housing 31 (rear h...

no. 2 Embodiment approach

[0284] Reference Figure 7 The second embodiment of the present invention will be described. The steering device of this embodiment differs from the structure of the first embodiment described above only in the structure of the outer column 13b.

[0285] In the case of this embodiment, the rear ends of the pair of column side plates 32a, 32b constituting the outer column 13b are not connected in the width direction, and the ring-shaped connecting portion 41 included in the structure of the first embodiment is not provided ( Reference Figure 1~4 ).

[0286] In the case of the present embodiment having the above-mentioned configuration, since the structure of the outer column 13b can be simplified, the manufacturing cost can be reduced.

[0287] The other structures and effects are the same as in the first embodiment.

no. 3 Embodiment approach

[0289] Reference Figure 8 The third embodiment of the present invention will be described. In the case of the steering device of this embodiment, the outer column 13c is arranged on the rear side (upper side), and the inner column 14a (refer to figure 1 Etc.) are arranged on the front side (lower side). Therefore, in the case of the present embodiment, the outer column 13c is arranged in the front-rear direction opposite to that in the first embodiment, and a cylindrical portion 72 is provided at the rear end, and in front of the cylindrical portion 72 A pair of column side plates 32a and 32b are provided. In addition, the front end portion of the outer column 13c is not the gear housing 31 ( figure 1 Etc.), but a spacer bracket 17b is integrally provided. In addition, the lower ends of the pair of side plate portions 52c, 52d constituting the spacer 17b are formed with elongated expansion and contraction adjustment long holes 21a, 21a corresponding to the second through ho...

Abstract

A pair of side plates (52a, 52b) of a distance bracket (17a) is positioned between a pair of support plates (36a, 36b), which constitutes a support bracket (18a), and a steering column (6a). When an adjustment lever (26a) for holding a steering wheel at an adjusted position is operated, the steering column (6a) is pushed up by column-pressing sections (56a, 56b) provided to the side plates (52a, 52b), and a pair of widened sections (58a, 58b) provided at the top of the side plates (52a, 52b) is pushed to the outside in the width direction. Moreover, the widened sections (58a, 58b) are sandwiched between the support plates (46a, 46b) and the steering column (6a). This configuration achieves a structure in which the retention force of the distance bracket is improved by the support bracket.

Description

Technical field [0001] The present invention relates to an improvement of a steering device for imparting a steering angle to the steering wheel of a vehicle such as an automobile. Background technique [0002] Regarding the steering device for a vehicle, for example, a device described in Patent Document 1 and the like is known in the past. Steering device such as Figure 52 As shown, the rotation of the steering wheel 1 is transmitted to the input shaft 3 of the steering gear unit 2, and a pair of left and right tie rods 4, 4 is pushed and pulled along with the rotation of the input shaft 3 to impart a steering angle to the wheels (front wheels). [0003] The steering wheel 1 is supported and fixed to the rear end of the steering shaft 5, and the steering shaft 5 is rotatably supported by the steering column 6 in a state where the cylindrical steering column 6 is inserted in the axial direction. In addition, the front end of the steering shaft 5 is connected to the rear end of th...
