DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side body structure around a front axle. The present invention relates to a side body structure in which both ends of a stabilizer that is expanded and bent are connected to each other.

[0002]

2. Description of the Related Art In recent years, various impact absorbing mechanisms have been proposed for automobiles in consideration of not only safety measures for running but also safety measures for collisions. For example, Japanese Patent Application Laid-Open No. Sho 61-15677 discloses a structure in which a front frame buckles and retreats at the time of a collision to reduce the impact.

[0003]

For example, a trunk room is provided at the front of an R / R vehicle (midship vehicle). Therefore, when a frontal collision occurs in such an R / R vehicle, When the trunk room is easily collapsed, the deformation amount is particularly large.

On the other hand, when the amount of deformation of the front portion is large, when the front axle is supported by the suspension structure 1 shown in FIG. 6, the front wheel 2 is largely deformed to the toe-in side as shown by a broken line at the time of a frontal collision. And retreated. For this reason, the wheel 2 escapes outside the side sill 3 provided at the lateral lower end of the vehicle body, and the load at the time of a collision cannot be received by the rigidly high side sill 3.

That is, in the suspension structure 1, a spindle 2 a that supports the front wheel 2 is supported via a lower arm 4 arranged in the lateral direction of the vehicle body, and the lower arm 4 is It is supported in the direction. Stabilizer 5
Has a substantially U-shape, an intermediate portion of which is supported by a vehicle body connecting member (not shown) on the front side of the lower arm 4 with respect to the vehicle body. It can be attached to. Reference numeral 7 denotes struts for vertically supporting the spindle 2a.

A knuckle arm 2b projecting forward from the spindle 2a is connected to a tie rod 8a of a steering linkage 8. When the steering wheel is steered, the tie rod 8a is moved in the axial direction. The vehicle is steered around the strut 7. The tie rod 8a is connected to a joint 8b.
Is connected rotatably to the main body side of the steering linkage 8, for example, a rack shaft.

Therefore, when a vehicle equipped with such a suspension structure 1 collides head-on, first, the stabilizer 5 moves rearward and presses the lower arm 4 at both ends thereof to push the spindle 2a rearward. At this time, the lower arm 4 is pivoted rearward about the bush 4a attached to the vehicle body, and the connection point P between the knuckle arm 2b and the tie rod 8a is pivoted rearward about the joint 8b.

In this state, since the lower arm 4 and the tie rod 8a are both rotated backward, the front wheel 2 is only moved backward without a large change in toe angle, but both ends of the stabilizer 5 are c The lower arm 4 is moved rearward while the both ends are further expanded outward in accordance with the rearward movement of the stabilizer 5 because the lower arm 4 is expanded in a character shape. For this reason, an outward pushing force is applied to the lower arm 4 by the expanding force of the stabilizer 5, and the lower arm 4 deforms the bush 4 a itself and the bush 4 a.
Along with the deformation of the vehicle body at the mounting portion a, the protrusion protrudes largely outward, and the front wheel 2 is largely changed in the toe-in direction.

Accordingly, as shown by the broken line in the figure, the rear portion of the front wheel 2 is disengaged outward from the side sill 3, and the impact load at the time of collision is received by the side sill 3 via the front wheel 2. And the deformation of the front part is increased.

In view of the above-mentioned problems, the present invention ensures that the front wheel, which is moved rearward during a frontal collision, abuts against the side sill to receive the impact load at the time of collision with the side sill. It is an object of the present invention to provide a side body structure in which deformation is reduced.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. 1 and 2 show an embodiment of a side body structure according to the present invention. FIG. 1 is a plan view of a front portion of a vehicle body in which a main part is sectioned. FIG. 2 is a main part corresponding to a portion A in FIG. It is an expanded sectional view.

That is, FIG. 1 shows an RR car (midship car).
10 shows a front portion, in which a trunk room 12 is formed inside a hood, and a spare tire 14 and the like can be stored in the trunk room 12. Therefore, in such an R / R vehicle 10, when a frontal collision occurs, the trunk room 12 is easily crushed, and the amount of deformation is particularly large.

Wheel houses 16 are formed on both left and right sides of the trunk room 12 in the vehicle body, and front wheels 18 are arranged in the wheel houses 16 respectively.
The front wheel 18 suspends the vehicle body via a suspension mechanism 20 and a steering linkage 22
Through the steering shaft 24.

The suspension mechanism 20 includes a lower arm 30 for connecting the spindle 26 of the front wheel 18 and the front side frame 28 of the vehicle body substantially in the lateral direction of the vehicle body, and a stabilizer 32 for restricting displacement of the lower arm 30 in the vehicle longitudinal direction. , And a strut 34 that regulates the vertical displacement of the wheel 18.

The outer end of the lower arm 30 is rotatably connected to the spindle 26 through a joint 30a, so that the wheel 18 can be steered.
A bush 30b is fixed to an inner end of the lower arm 30 in the vehicle body, and the lower arm 30 is connected to the front side frame 28 via the bush 30b so as to be vertically swingable.

The stabilizer 32 is formed in a substantially U-shape as a whole, and an intermediate portion 32a is disposed in the left-right direction of the vehicle body, and is attached to the front side frame 28 in front of the lower arm 30 in the vehicle body. Further, both ends 32b of the stabilizer 32 are expanded and bent in a C-shape toward the rear of the vehicle, and each of the distal ends penetrates near the outer end of the lower arm 30, and is formed at the projecting end. The nut 36 is screwed and fixed. Therefore, the stabilizer 32 provides the original torsional rigidity to the vertical swing of the lower arm 30 and also functions as a suspension arm because it regulates the forward and backward movement of the lower arm 30.

The steering linkage 22 is configured as a rack and pinion type, and a rack shaft 40 is housed in a rack housing 38 fixed to the vehicle body at the vehicle front side of the lower arm 30 so as to be movable in the axial direction. Joints 42 are provided at both ends of the rack shaft 40.
A tie rod 44 is rotatably connected via a knuckle arm 46 projecting forward of the spindle 26 from the vehicle body via a joint 48.

The lower end of the wheel house 16 in which the front wheel 18 is housed is located on the rear side of the vehicle body.
A front end of the vehicle body of a side sill 50 that is disposed at the front and rear lower ends of the vehicle body to reinforce the vehicle body is located.

In this embodiment, the side sill 50 is provided at the front end portion of the vehicle body facing the inside of the wheel house 16 with a claw portion 52 facing the rear side of the tire 18a of the front wheel 18. The claw portion 52 is configured between the inner panel 50a and the outer panel 50b of the side sill 50 as shown in FIG. still,
This figure is an enlarged cross-sectional view of the right side of the vehicle, which is symmetrical to the part A shown in FIG. 1, and the part A is upside down in the figure.

The side sill 50 includes an inner panel 50.
a is provided between the inner panel 50a and the outer panel 50b.
The front end (the left end in the figure) of the vehicle body is a spot welded to an apron panel 16 a defining the wheel house 16. The claw member 52 includes first and second steel plates 52a,
The reinforcement 52 and the apron panel 16a are attached via bolts and nuts so as to cover the outside of the corner C where the reinforcement 54 and the apron panel 16a are joined. At this time, the L-shaped bent portion of the claw member 52 is bulged outward of the vehicle body, and a closed cross section is formed between the claw member 52 and the reinforcement 54. The outer panel 50b is disposed outside the claw member 52, and the claw member 52 is covered and hidden by the outer panel 50b.

In the side body structure according to the present embodiment having the above-described structure, when the vehicle collides head-on, the buckling deformation of the front side frame 28 causes the intermediate portion of the stabilizer 32 as shown in FIG. Is moved backward, and the lower arm 30 fixed to both ends 32 b of the stabilizer 32
And the lower arm 30 is pushed outward with the expansion of both ends 32b of the stabilizer 32, and as a result, a joint 30a connecting the lower arm 30 and the spindle 26 draws a locus of T1 in the figure. Move to the rear and outside of the vehicle. On the other hand, a joint 48 for connecting the tie rod 44 and the knuckle arm 46 moves rearward and inward around the base joint 42 of the tie rod 44 along a locus T2 in the drawing. Accordingly, the front wheel 18 is moved backward while largely pointing to the toe-in as shown by the two-dot chain line in FIG.

At this time, in this embodiment, the side sill 50 is provided at the front end of the vehicle body facing the inside of the wheel house 16 with the claw portion 5 facing the rear side of the tire 18a of the front wheel 18.
2, the claw portion 52 hooks the tire 18a of the front wheel 18 which is moved backward while largely pointing in the toe-in direction.
Further forcibly prevents it from pointing in the toe-in direction.
Therefore, since the front wheel 18 is retracted while being caught by the claw portion 52, the front wheel 18 can be brought into contact with the side sill 50. For this reason, the impact load at the time of a collision transmitted to the front wheel 18 can be received by the front end portion of the rigid side sill 50, so that the front portion of the vehicle body is prevented from being further deformed. Thus, it is possible to minimize the influence of the deformation on the passenger compartment, thereby protecting the occupant.

In the above-described embodiment, the first and second steel plates 52a and 52b constituting the claw portion 52 are the same as the second steel plate 52b.
The outer end of the vehicle body is bent rearward to be welded to the front end of the first steel plate 52a.
The configuration shown in FIG. 3 is not limited to this, and the configuration shown in FIG. That is, in the same figure, the first steel plate 52a is further extended forward of the vehicle body, and the outer end of the second steel plate 52b is bent forward of the vehicle body, so that the bent portion of the second steel plate 52b and the first steel plate 52b Are welded to each other to form a hooked portion 52c projecting forward of the vehicle body at the welded portion. The hooked portion 52c makes it easier to grip the tire 18a. .

FIGS. 4 and 5 show another embodiment, in which the same components as those in the above-mentioned embodiment are denoted by the same reference numerals, and a duplicate description will be omitted. FIG. 4 is an exploded perspective view of a main portion of the right side of the vehicle body front portion as viewed from above, and FIG. 5 is an exploded perspective view of the main portion of the same portion viewed from below.

That is, in this embodiment, the displacement of the lower arm 30 to the outside of the vehicle body due to the large toe-in change of the front wheel 18 shown in FIG. 1 is suppressed. This is to improve the rigidity of the attachment 30 to the vehicle body side.

As shown in FIG. 4, the side frame 28 to which the lower arm 30 is attached is provided with a dash panel 60.
Protruding portion 28 protruding inward of the vehicle body in the vicinity of
a is formed, and the lower arm 3 is provided below the protruding portion 28a.
0 bush 30b is attached. A stepped corner portion 64 is formed between the tip of the projecting portion 28a and the dash lower panel 62.

In this embodiment, a triangular gusset plate 66 is disposed at the corner 64, and two sides of the gusset plate 66 are fixed to the projection 28a and the dash lower panel 62 by welding.

Further, as shown in FIG.
8a and a tie bar 68 is fixed by bolts so as to straddle between the lower side of the front side frame 28 and the front end of the front side frame 28,
A lateral support bar 70 connects between the rear end portions of the tie bars 68 provided on both sides of the vehicle body. When the front end of the lateral support bar 70 is bolted to the front side frame 28, an intermediate portion of the stabilizer 32 shown in FIG. 1 is fastened to the lateral support bar 70 together.

Therefore, in this embodiment, the vicinity of the mounting portion of the lower arm 30 on the vehicle body side is reinforced by the gusset plate 66, and the vehicle body rigidity of the mounting portion of the lower arm 30 can be improved. In addition, since the tie bars 68 are connected by the lateral support bar 70 as a connecting member, remarkably large rigidity can be given to the pulling force of the mounting portion of the lower arm 30 to the outside of the vehicle body.

Therefore, at the time of a head-on collision, the stabilizer 32
Due to the expanding forces at both ends of the lower arm 30, the amount of outward movement of the lower arm 30 that is to be pushed outward is significantly reduced, and a large toe-in change of the front wheel 18 can be suppressed. Therefore, the front wheel 18 that is retreated by the collision can be brought into contact with the front end of the vehicle body of the side sill 50 shown in FIG. 1, and the impact load can be received by the side sill 50 as in the above embodiment.

In this embodiment, the gusset plate 66
And a lateral support bar 70 are disclosed. However, the gusset plate 6
6 or the lateral support bar 70 is provided alone, it is possible to improve the rigidity of the vehicle body mounting portion of the lower arm 30 and prevent a large change in the toe-in of the front wheel 18.
