Description

[Detailed explanation of the idea] The present invention relates to a vehicle body structure.

As shown in FIGS. 1 and 2, a pair of left and right front frames 01 and 02 are combined with left and right wheel house inner panels 03 and 04 that form a front wheel house, forming a front frame that forms a vehicle body strength member. In the conventionally known frame structure 05 equipped with a frame, the steering gear box 06 is provided inside the vehicle body of the right front frame 01 in the case of a right-hand drive specification as shown in FIG. 2a, and as shown in FIG. 2b. For left-hand drive models, the steering gear box 07 is attached to the left front frame 0.
It is installed inside the vehicle body.

That is, the steering wheel box 06 has a steering wheel 010 at its upper end as shown in FIGS. 7 and 8.
An arm 014 is connected to the lower end of the steering gear box 06, and the arm 014 is connected to a steering rod and a front wheel (not shown).

Also, the mounting flange 08 of the steering gear box 06
A surface 016 that contacts the inner side surface of the vehicle body of the right front frame 01 is formed into a substantially flat surface, but a protrusion 018 is formed on the opposite surface.

Therefore, in the case of a left-hand drive specification, if the steering gear box 06 is moved toward the interior of the vehicle and attempted to be attached to the side surface of the vehicle interior of the left front frame 02, the protrusion 018 will get in the way. A steering gear box 07 having a symmetrical shape was made and its mounting flange 09 was fixed to the side surface of the left front frame 02 inside the vehicle body.

As a result, two types of steering gearboxes 06 and 07 were required for right-hand drive specifications and left-hand drive specifications, resulting in an increase in the price of the steering gearboxes.

The present invention was proposed in view of the above, and includes a pair of left and right front frames that are combined with a foil house inner panel that forms a front wheel house and has a closed box-shaped cross section, and the same left and right front frames. One of the frames is bent inward of the vehicle body, and the wheel house inner panel corresponding to the same front frame and the one front frame are separated in the direction of the interior of the vehicle at the joint portion to form a gap. For either the specification or the left-hand drive specification, it is attached to the outside surface of the vehicle body of one of the front frames in the above-mentioned gap, and for either the right-hand drive specification or the left-hand drive specification, it is attached to the inside surface of the other front frame of the left and right front frames. The main idea is that the vehicle body structure is characterized in that the same steering gear box can be installed in each vehicle.

According to the above structure, one of the left and right front frames is bent inward of the vehicle body to form a gap in the interior direction of the vehicle between the wheel house inner panel corresponding to the same front frame and one front frame. The steering gear box of either a left-hand drive specification car or a left-hand drive specification car is attached to the outer side of the vehicle body of one of the front frames in the above gap, and the other steering gear box of either a right-hand drive specification car or a left-hand drive specification car is attached to the left and right front frames. It is designed to be attached to the side of the vehicle body on the other front frame, and by moving the steering gear box for right-hand drive specifications toward the inside of the vehicle while maintaining approximately the same posture, it can be attached to the front frame as a steering gear box for left-hand drive specifications. As a result, the same steering wheel box can be used for both right-hand drive and left-hand drive specifications.

Next, an embodiment of the present invention will be described with reference to FIGS. 3 to 6.

1 is the right front frame 2 and the left front frame 3
and a frame structure in which both are connected to a dash panel 4 that separates an engine room 30 and a vehicle compartment 31,
In this embodiment, a cross member 4' connects both front frames 2 and 3.

The right front frame 2 is directly spot welded to the lower end of the right wheel house inner panel 6 of the vehicle body panel 5 except for the gap 11 described later, that is, at the front of the vehicle body, and the left front frame 3 is connected to the lower end of the left wheel house inner panel 7. are joined by direct spot welding.

8 is a reinforcing member provided in the right front frame 2, 9 is a reinforcing member provided in the left front frame 3, and 10 and 10' are provided in press-formed openings of the front frames 2 and 3, respectively. This front frame force bar has a cross section of the front frame shaped like a closed box.

11 gradually bends the right front frame 2 inward of the vehicle body so that the right front frame 2 is located inside the vehicle body from the symmetrical position of the left front frame 3 with respect to the vehicle body center line extending in the longitudinal direction of the vehicle body. This is a gap formed by separating the outer surface of the vehicle body from the lower end of the right wheel house inner panel 7.

The gap 11 is slightly larger near the front of the dash panel 4 than the mounting flange 09 of the steering gear box 07.

Reference numeral 16 denotes a frame force bar provided to cover the gap 11, and the frame force bar is integrally formed as an extension of the front frame force bar 10.

The above frame force bar 16 is the steering gear box 0
It has a hole 14 shaped so that the flange 09 for attaching the flon 1 to the frame of No. 7 can be inserted therein, and the hole 14 is formed into a burred hole in which a flange 15 is integrally provided.

Reference numeral 17 denotes a bolt/hole provided in the right front frame 2, into which a bolt 18 corresponding to the mounting flange 09 of the steering gear box 07 is fitted. It is tightened with a nut 20.

Reference numeral 21 denotes a mud-proof force bar that seals the gap created between the frame force bar 16 and the steering gear box 07 after the steering gear box 07 is installed through the hole 14 of the frame force bar 16; is in contact with the steering gear box 07, and the other end 23 is connected to the frame force bar 16 by a tapping screw 24.
is fixed to.

With the above structure, as shown in FIG. 4a, in the case of the right-hand drive specification, the above-mentioned Steering gearbox 0
7 and tighten the nut 20 onto the bolt 18 from the wheel house inner panel 6 side to secure the steering gear box 07 to the right front frame 2 of the frame structure 1, and then attach the mud-proof cover 21 to the wheel house inner panel 6. By fixing from the side, splashed waterproofing from the foil house inner panel 6 is prevented from entering into the engine room 30.

In addition, as shown in FIG. 4b, in the case of left-hand drive specifications, the engine compartment 30 of the left front frame 3 is
The above-mentioned steering gear box 07 is arranged on the side, and is fixed via bolts 18' and nuts 20' in the same manner as the above-mentioned right-hand drive specification.

Therefore, according to the present invention, the same steering gear box can be used regardless of the right-hand drive specification or the left-hand drive specification, and parts can be made common, making the work inexpensive and easy.

In addition, even in the case of the right-hand drive model mentioned above, the frame force bar and anti-mud cover prevent muddy water flying inside the wheel house from entering the engine room, extending the life of the engine and auxiliary equipment, and improving durability. will improve.

In the above embodiment, the right front frame 2 is bent toward the engine compartment to provide a gap 11 between the right wheel house inner panel 6 and the steering gear box 07, but the left front frame 3 is bent toward the inside of the vehicle body. Even if the gap is provided between the inner panel 7 and the left wheel house inner panel 7 by bending it, the same effects as in the above embodiment can be obtained.
