Description

[Detailed Description of the Invention] This invention relates to a support mechanism for a steering column in a one-box type light vehicle or the like.

First, the formation of a conventional support mechanism for a steering column in an automobile will be explained with reference to FIG.

A reinforcement reinforcement 2 is provided as a lining on the inner wall of the front panel 1 at an intermediate height, and a floor bracket 4 having a U-shaped cross section is erected at the front end of the passenger compartment floor 3. The left and right side portions of the front end of a rearwardly projecting flat plate-like upper bracket 5 are fastened to the left and right mounting holes in the upper portion of the forcement 2 with screws 6.

In addition, the front upper ends of the left and right pair of parallel pedal supports 7 are fastened with screws 8 to the two left and right mounting holes at the bottom of the reinforcement reinforcement 2, and the lower ends of both pedal supports 7 are tightened with screws 8, respectively. The end plates connecting the two are fastened to the floor bracket 4 with screws 17.

Further, a column support bracket 9 having an L-shaped cross section is assembled between the rear end edge of the upper bracket 5 and the upper end edge of both pedal supports 7, and a column support bracket 9 is assembled between the rear end edge of the upper bracket 5 and the upper end edge of both pedal supports 7. are assembled and held at two locations, an upper end and a lower end, at the upper end and the lower end of the rear half obliquely rising surface of the support bracket 9.

In addition, between both sides of the atsupah bracket 5 and the column support bracket 9, there are reinforcing plates 1 on the left and right.
2 is stretched to strengthen the assembly strength.

In addition, the brake operating members are usually attached to the above-mentioned support mechanism, and as shown in the figure, the brake cylinder 13 and the brake booster 14 are attached to the board of the column support bracket 9, and the brake pedal 15 is attached to the brake cylinder 13 and the brake booster 14. Shaft 1
6 is supported by the pedal supports 7 on both sides.

However, in the conventional support mechanism configured in this way, the mounting points of the brake cylinder 13 and the brake booster 14 are surrounded by a large number of brackets, reinforcing plates, etc. When installing and removing the booster 14 and brake pedal 15, it is difficult and troublesome to take them in and out and assemble them, as well as the number of pins 6, 8, and 17 required to attach the support mechanism to the vehicle body. In particular, it was difficult to tighten and loosen the screws 8 at intermediate height, which resulted in poor workability during maintenance.

Therefore, the object of the present invention is to provide a structural technology for a steering column support mechanism that facilitates both the attachment and detachment of the support mechanism to the vehicle body and the attachment and detachment of the brake member to and from the mechanism.

In order to achieve this purpose, in the configuration of the present invention, a cross member is suspended horizontally at an intermediate height of the front end of the passenger compartment, a floor bracket is erected at the front end of the passenger compartment floor, and a pair of left and right pedals are installed.・A support that also serves as a column is screwed to the floor bracket and cross member so that they stand side by side, and a lower bracket is fixed at the middle height of the support.
A structural method is adopted in which the upper end and lower end of the steering column are assembled and held in the upper bracket fixed to the rear extending end of the support and the lower bracket, respectively, and a surrounding space is formed. , the structure between the front panel and the steering column has been simplified.

Hereinafter, the configuration of the present invention will be specifically described with reference to an embodiment shown in FIGS. 2 and 3.

In the support mechanism of the embodiment, the floor panel 1
A cross member 18 is horizontally mounted near the inner wall at the middle height of the vehicle, and a floor bracket 4 is provided upright at the front end of the vehicle interior floor 3. The column supports 19 and 20 extend from the left and right sides of the floor bracket 4 to the cross member 18 and extend rearward, and the end plates 21 connecting the lower ends thereof are connected by screws 22. floor bracket 4
Each support 19,
The front upper ends of 20 are fastened and fixed to the cross member 18 by screws 23, respectively.

Further, between the hypotenuses formed at the intermediate height of both supports 19 and 20, a lower bracket 24 formed to have an L-shaped cross section by a hollow board field 24a and a rising portion 24b is spread and fixed. , an upper bracket 25 is assembled and suspended horizontally between the rear extending ends of both supports 19, 20.

Thus, the steering column 11 to which the wheel 10 is attached has its upper end assembled and held by the upper bracket 25, and its lower end is assembled and held by the rising portion 24b of the lower bracket 24.

In addition, the board area 24a of the lower bracket 24
A brake booster 14 and a brake cylinder 13 are assembled to the brake pedal 15, and the shaft 16 of the brake pedal 15 is attached to both supports 19, 20.
bearings.

Note that the reference numeral 26 indicates a pedal stopper, and the reference numeral 27 indicates a seat.

By the way, in the steering column support mechanism of the embodiment configured in this way, the board area 24
Since the upper part and left and right sides of a are open spaces, it is extremely easy to install, remove, and assemble brake members such as the cylinder 13, booster 14, and pedal 15. Screw 2
2, 23 has been reduced to 3 (previously, screws 6, 8,
17), and since both screws 22 and 23 face a wide space, it is extremely easy to attach and remove the support mechanism from the vehicle body.

As described above, according to the steering column support mechanism according to the present invention, a pair of parallel pedal/column supports, a lower bracket fixed to the middle stage of the supports, and a rear extending end of the supports are provided. The upper bracket, which is fixed to This greatly simplifies the structure between the support mechanism itself, and
This simplifies the work of attaching and detaching attached parts, improving workability during assembly and maintenance of the support mechanism.In addition, the above-mentioned supports are fastened to the floor bracket and cross member at three locations with screws, increasing installation strength. increases.

Moreover, the surrounding space can also enhance the driver's safety in the event of a head-on collision.
