AI Technical Summary

Problems solved by technology

Therefore, it is conceivable to increase the thickness of the outer column 11a or to manufacture the outer column 11a from an iron-based material, but in this case, problems such as an increase in the weight of the entire steering column arise.

Embodiment Construction

[0049] [First example of embodiment]

[0050] Figure 1 to Figure 15 The first example of the embodiment of the present invention is shown. This example is characterized by a structure that ensures sufficient strength even when an anti-theft key lock system is incorporated, and is used to enable the front and rear positions of the steering wheel to be adjusted or The work of maintaining the adjusted position is performed smoothly. The structures, functions, and effects of other parts, including the structure of the electric power steering device, are the same as those of the conventional structure. Therefore, the following description will focus on the characteristic parts of this example.

[0051] The telescopic steering device of this example includes a steering column 2a, a steering shaft 3a, a support bracket 17a, an adjustment lever 24a as a rod-shaped member, and a cam device 29 as an adjustment mechanism. The steering column 2a is composed of an inner column 10a and...

Abstract

The present invention realizes the structure of the outer column for the telescopic steering device, which can ensure sufficient strength even when the steering lock device is incorporated, and can ensure the stability of the steering wheel. The front and rear positions can be adjusted or maintained at the adjusted position for smooth operation. At the ends (58a, 58b, 58b, 58a, 58b), the portion closest to the end (58a) present on the portion closest to the through hole (37a) for locking and the farthest end existing at a diagonal position with respect to the closest end (42a) The rigidity of the part (59a) is higher than that of the end parts (58b, 59b) of the remaining two parts. In addition, convex portions (61a, 61b) are respectively provided at two positions spaced apart in the vertical direction on the outer surfaces of the pair of clamped plate portions (20a, 20b).

Description

technical field [0001] The present invention relates to a telescopic steering device capable of adjusting the front-rear position of a steering wheel, and an outer column used in the telescopic steering device. Background technique [0002] In order to impart steering angles to the steered wheels (usually the front wheels) of motor vehicles, widely used Figure 18 Steering gear shown. In this steering device, a steering shaft 3 is rotatably supported on the inner diameter side of a cylindrical steering column 2 supported by a vehicle body 1 . A steering wheel 4 is fixed to a rear end portion of the steering shaft 3 protruding rearward beyond the rear end opening of the steering column 2 . The rotation of the steering wheel 4 is transmitted to the input shaft 8 of the steering gear unit 7 via the steering shaft 3 , the universal joint 5 a , the intermediate shaft 6 , and the universal joint 5 b. The rotation of the input shaft 8 pushes and pulls a pair of tie rods 9 dispose...
