Description

[Detailed Description of the Invention] This invention relates to an improvement of a radiator support structure for an automobile.

Conventionally, the radiator support structure for automobiles is
As in the structure shown in FIGS. 1 and 2 disclosed in Japanese Utility Model Application No. 53-104836, a bracket is provided to support the radiator 3 on the shroud upper 1 and the cross member 2 via elastic members 4, 4. 5, 5 is fixed, but in this structure, if the radiator 3 acts as a dynamic damper, a high load will be applied to the shroud upper 1 via the bracket 5 during upward movement, so the shroud will not be damaged. There was a risk that the bracket fixing part for par 1 would be deformed.

This idea was made in view of the above conventional problems, and basically consists of a bracket fixing part of the shroud upper that fixes the bracket that supports the upper part of the radiator, and a cross member between the shroud upper and the cross member. The rigidity of the shroud upper is improved by connecting the side panel flange fixed to the radiator with a reinforcing member to prevent the shroud upper from deforming due to upward movement of the radiator. It is.

Hereinafter, embodiments of this invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 3 and 4, a shroud upper 12 with a channel-shaped cross section extending in the width direction of the vehicle body is installed at the front of the wheel aprons 11, 11 on both sides of the engine room 10, with the open side facing downward. A closed cross-section cross member 13 (third
(see figure) are connected to the wheel aprons 11, 11.

The side panel 15, which has a radiator opening 14 formed in the center thereof, extends in the width direction of the vehicle body, and its upper portion is fixed to the front back side of the shroud upper 12.
The lower part is fixed to the front surface of the cross member 13.

The side portions 15a, 15a of the radiator opening 14 of the side panel 15 are bent at right angles toward the engine compartment 10, and the bent ends of the side portions 15a, 15a are further inward in parallel with the shroud upper 12. The flanges 15b, 15b are bent, and the upper part 15c of the flanges 15b, 15b is
The upper end 15d is fixed to the lower surface of the shroud upper part 12 by curving the front back side of the shroud upper part 12, and a space is formed between the upper part 15c and the shroud upper part 12 through which a wire harness or the like is inserted. .

As shown in FIGS. 6 and 7, the vertical wall 12 of the shroud upper 12 on the engine room 10 side
a and the flanges 15b, 15b of the side panel 15
The lower part of the reinforcing members 16, 16 is connected to the flanges 15b, 15b.
A bolt 17 is inserted through the flat surfaces 15e, 15e of the radiator 19, and is fastened and fixed with a nut 18, and the upper part of the reinforcing member 16, 16 is a bracket 20, which supports the upper part of the radiator 19 via an elastic member (rubber) 23. A clamp bolt 21 is inserted between 20 and the shroud upper 12 and fastened and fixed with a nut 22.

On the other hand, as shown in FIG. 5, an elastic member (rubber) 25 is interposed between the lower part of the radiator 19 and a bracket 24 fixed to the cross member 13, and the radiator 19 is inserted into the hole 26 of the bracket 24. The structure is such that the cylindrical protrusion 27 is fitted together with the elastic member 25 and supported.

The elastic member 25 has a lower part of the radiator 19.
It is preferable to have a nonlinear characteristic in which the spring constant is small up to a predetermined stroke during vertical displacement, and becomes large after the predetermined stroke.

With the support structure for the radiator 19 as described above, even if the radiator 19 undergoes vertical fluctuation, the upward fluctuation is regulated by the elastic member 23, and the downward fluctuation is controlled by the elastic member 25, which acts as a dynamic damper within a constant acceleration range. I come to do it.

Further, since the rigidity of the shroud upper 12 is improved by the reinforcing members 16, 16, there is no possibility that the shroud upper 12 will be deformed during upward movement.

In the above embodiment, as shown in FIGS. 8 and 9, falling portions 16'a and 16'b are provided on both sides of the reinforcing members 16' and 16' to sandwich the flanges 15b and 15b of the side panel 15. and reinforcing member 1
The bolts 6' and 16' are prevented from rotating when the bolts are tightened, and at the same time, the rigidity of the reinforcing members 16' and 16' is improved.

As is clear from the above explanation, this invention connects the bracket fixing part of the shroud upper for supporting the radiator and the flange of the side panel with a reinforcing member, so that the rigidity of the shroud upper is increased. The performance has been further improved, and there is no longer any risk of the shroud upper being deformed even when high loads are applied during radiator fluctuations.
