Abstract

PURPOSE:To improve the running performance on a rough road by providing a cross member connecting the right and left side frames at the lower position of a steering support member connecting the right and left hinge pillars, and connecting it to the support member with a connection section. CONSTITUTION:A steering support member 18 connecting the right and left hinge pillars 13, 13 is extended in the vehicle width direction in parallel with the horizontal portion 5b of a cross member 5. A pair of the right and left connecting members 19 fixed to the steering support member 18 at the upper section and fixed to the horizontal portion 5b of the cross member 5 at the lower end are provided. The support member 18 supporting a steering column is connected to the cross member 5, thus steering support rigidity is improved, and the running performance on a rough road is improved.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a steering support structure for an automobile.

(Prior Art) Conventionally, as disclosed in, for example, Japanese Utility Model Application Publication No. 1-93173, a steering support structure is known in which a steering column is supported by a support member connecting left and right hinge pillars via a bracket. .

By the way, in the conventional structure described above, the steering column is supported by the support member, so the support rigidity of the steering column is improved. However, in vehicle models that often drive on rough roads, it is necessary to further increase the support rigidity. There is a need.

(Objective of the Invention) Accordingly, it is an object of the present invention to provide a steering support structure suitable for automobiles that often drive on rough roads.

(Structure of the Invention) The present invention provides a cross member that connects the left and right side frames at a position below the support member in a configuration in which a steering column is supported by a support member that connects left and right hinge pillars and extends in the vehicle width direction. and a connecting member that connects the cross member and the support member in the vertical direction (Advantageous Effects of the Invention) According to the present invention, the support member that supports the steering column is connected Since the member is strongly connected to the loss member, the steering support rigidity is significantly improved.

Furthermore, since the left and right side frames are connected by a cross member, the rigidity of the vehicle body is also improved.

(Example) Hereinafter, an example in which the present invention is applied to an automobile in which the engine compartment is provided below the floor of the driver's seat will be described with reference to the drawings.

1 and 2 show a first embodiment of the present invention, 1
is the driver's cabin, 2 is the engine room that houses engine 3,
Reference numeral 4 denotes side frames extending in the longitudinal direction of the vehicle body on both sides of the engine room 2.

A vibrator-shaped cross member 5 is attached to the rear end of the engine room 2 to connect the left and right side frames 4.4. This cross member 5 has left and right vertical portions 5a, 5a whose lower ends are fixed to the inner surfaces of the left and right side frames 4.4 and extends upward, and both vertical portions 5a, 5a.
It consists of a horizontal part 5b that connects the upper ends and extends in the vehicle width direction, and a part 1 in which these parts 5a, 5b, and 5a are bent.
It is integrally formed from the vibrator material of the book.

The floor 6 of the driver's cab l is located on the left and right side frames 4.4.
The rear end of the engine room 2, which is fixed to the surface and in which the cross member 5 is disposed, protrudes into the interior of the engine compartment 1. For this reason, a service hole 8 is open extending from the dash panel 7 to the floor 6, but this service hole 8 is normally covered with a cover 9.

The left and right front pillars 10 are front pillar inner 1
Closed cross section 1 by 0a and front pillar outer tob
1, the front 1 to the pillar inner lOa are integrally connected to the cowl side panel 12 below.
Together, they constitute hinge pillars 13 for both side doors (not shown) of the driver's cab 1.

The cowl panel 15, which connects the left and right hinge pillars 13, 13, extends in the vehicle width direction, and supports the windshield 14 at its front edge, includes a cowl upper panel 15a, and a cowl upper panel 15a.
The cowl upper panel 15a and the rear end of the cowl under panel 15b form a closed section 17 together with the reinforcing panel 16, and form a steering support member 18 that connects the left and right hinge pillars 13 and 13. It consists of The steering support member 18 extends in the vehicle width direction above the horizontal portion 5b of the cross member 5 and parallel to the horizontal portion 5b.
A steering column 20 is provided with a pair of left and right connecting members 19 whose upper ends are fixed to the steering support member 18 and whose lower ends are fixed to the horizontal portion 51 of the cross member 5. The steering column 20 is supported by the steering support member 18 via a bracket 21 whose front upper end is fixed to the steering support member 18 and extends rearward and downward. 22 is a steering shaft passing through the steering column 20;
23 is a steering wheel.

The above is the structure of the automobile steering support according to the first embodiment of the present invention, and the support member 18 supporting the steering column 20 is connected to the cross member 5 by the connecting members 19 and 19. It can do two things: improve steering support rigidity.

Next, FIG. 3 shows a second embodiment of the present invention, in which parts corresponding to those of the first embodiment are given the same reference numerals.

In the case of this embodiment, the steering support member 18 connects the left and right hinge pillars 13, 13 and extends in the vehicle width direction.
is provided separately from the cowl panel 15, and a steering column (not shown) is supported by the steering support member 18 via a bracket 21.2. In this embodiment, the cross member 5 is provided below the steering support member 18 to connect the left and right side frames 4.4, and the steering support member 18 and the cross member 5 are connected as a pair. They are connected by members 19.19. Therefore, it is clear that this second embodiment of the present invention also has the same effects as the first embodiment described above.
