Description

[Detailed description of the invention] Fields of use of M-Rakudo The present invention relates to a wheel house structure.

BACKGROUND OF THE INVENTION Various structures are employed in wheel houses such as front wheel houses of automobiles in order to resist external input from front suspensions and the like.

This example will be explained with reference to figure M4.6. Reference numeral 1 indicates a wheel house formed on the hood ridge panel 2. Lower housing 4
A part of the outer side of the upper housing 3 is joined to the two-K IJ reinforcement 5 which has a closed cross-section structure, and a lower edge of the lower housing 4 is formed into a closed cross-section structure by a closing plate 6. It is joined to the closing plate 6 of.

In addition, as shown in FIG. 5, in the support part of the shock absorber, an opening part 8 is formed in the upper housing 3, and an upper mount reinforcement 9 of the shock absorber is attached to the moat around the opening part 8 from a@. At the same time as joining, the upper mount reinforcement 9 is attached to the portion extending from the inner surface of the side member 7 to the upper end of the lower housing 4.
41c 9 The reinforcing materials 10 to be joined are joined. The general surface of the lower housing 4 is offset to the outside of the vehicle, and another reinforcing material 11 is bonded to a portion extending from the upper end of the lower housing 4 to the inner 1111 surface of the side member 7. Furthermore, FR is heavy W4tJV! Indicates I.

Then, the reinforcing material 10 is joined to the corner portions of the upper housing 3 and the lower housing 4 by extending the reinforcing portion 10a to form a closed cross section, and this reinforcing material 0
and the upper housing 3 and the base end L2a of the upper link 120 of the fake suspension are fastened with the nut 13 (this similar fermentation is described, for example, in Automotive Technology VOL 37 M
ol 1983 No. 1080).

Problems to be Solved by the Invention Although the reinforcement members 10 and 11 have a structure that can partially resist input charges from the upper link 12 and a shock absorber (not shown), the upper link 1
2, the general parts of the upper housing 3 and lower housing 4 have I'1l-t! The load becomes low and swells, making it impossible to efficiently distribute the load to the douage member 7 and hood ridge reinforcement 5, which causes problems in terms of silkworm resistance and durability, and increases the number of parts. It has been pointed out that this is a problem.

Therefore, the present invention provides a wheel house structure that can efficiently distribute the input load from the suspension and the like to the hood ridge reinforcement and side members, and has excellent vibration isolation and durability.

A means to solve the problem is to form a part of the wheel house with a closed section structure that extends from the hood ridge reinforcement to the side members.

To effectively share the load input from an action suspension or the like to a hood ridge reinforcement and a side member t1.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings, in which the same parts as those of the conventional structure are denoted by the same reference numerals.

In FIGS. 1 and 2, numeral 1 indicates a wheel house formed on the hood ridge panel 2, and this wheel house 1 only has a strut housing S8a.

The upper edge of the wheel house 1 is joined to the lower edge of the hood ridge reinforcement 5 formed in a closed cross-sectional structure, and the lower part of the wheel house 1 is joined to a side member 7 having a hat-shaped cross section. It is formed into a closed cross-sectional structure.

Then, at the rear of the strut housing S, a reinforcing material 14 having a hat-shaped cross section is installed at the periphery of the reinforcing material 14 at a portion where the upper surface of the wheel house 1 is passed from the hood ridge reinforcement 5 to the side member 7. It is joined by a flange portion t provided at the flange portion t. Therefore, the closed section structure section 14 that connects the closed section structure section 50 of the hood ridge reinforcement 5 and the closed section structure section 70 of the side member 7 between the reinforcing material 14 and the wheel house 1
0 is formed, and the base end L2a of the upper link 12 of the suspension (for example, double wishbone type) is fastened to the wheel house l and the reinforcing member 14 forming the closed cross-section structure 140 with a nut 13. .

According to the structure of the above embodiment, the closed section structure 140 formed by the upper distribution reinforcing member 14 can sufficiently counter the fi electric current input from the upper link 12 old J and shock absorber. The input load is applied to each closed section structure section 5 of the hood ridge reinforcement 5 and the side member 7.
0 and 70 can be efficiently shared, durability and preventive properties can be improved. Therefore, it can be sufficiently applied to heavy vehicles such as anti-skid vehicles where a relatively large number of auxiliary devices are installed.

In addition, even if an excessive load is applied to the side member 7 and the side member 7 attempts to deform in the direction of bending, such as when the front side of the vehicle is 1lJA, the hood is ridge rain force 5
Since the load can be shared by the closed section structure portion 50 of the side member 7, bending of the side member 7 can be prevented.

Furthermore, since the number of imaginary parts is small and the structure is simple, it can be handled at low cost. 6. The reinforcing material 14 may be extended to the range shown by the chain line in FIG. .

Next, in the embodiment shown in FIG. 3, a closed cross-section structure section 140 formed by the reinforcing material 14 is disposed across the strut housing S.

Also in this embodiment, the side member 7 is joined to the lower edge of the strut housing S, and the hood ridge reinforcement 5 is joined to the outer edge of the strut housing S.
Closed section structure part 14 formed of each closed space surface structure part 70°50 of reinforcement material 14 and stock 1 housing S
By making it continuous at 0, durability and preventive properties can be improved.

In addition, 9 in FIG. 3 indicates the shock absorber mount reinforcement, the lower edge is joined to the periphery of the opening 8 of the strut housing S, and the upper surface is joined to the periphery of the opening 1'f [111] of the reinforcing member 14. ing.

Incidentally, the present invention is not limited to the above-described embodiment; for example, in the embodiment shown in FIG. 2, the front side portion of the reinforcing member 14 may be joined to the strut housing.

As described in detail, according to the present invention, the load input from the suspension etc. can be effectively shared between the hood ridge reinforcement and the side members, thereby improving durability and vibration isolation. This has a great practical effect.

Additionally, even if an excessive input load acts on the rear member during a vehicle collision and the side member attempts to deform in the direction of bending, this input load cannot be shared by the hood ridge reinforcement. This makes it possible to minimize deformation of the vehicle body in the event of a collision.

In addition, since the structure is simple and the number of parts is small, it is easy to assemble and maintain accuracy, and work costs can be reduced, resulting in overall cost reduction.
