Abstract

PURPOSE:To prevent the slip-off trouble from a radiator supporting device when a radiator of an automobile is applied with a large pushing-up force. CONSTITUTION:The front end 12a of a bracket 12 which holds the upper part of a radiator 10 is joined with the front flange 11a of an upper frame 11, and the rear end edge 11a of the upper frame 11 is attached on the upper surface of the intermediate part between a joint part 17 and the holding part 18 of the radiator 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for a radiator in an automobile.

[0002]

2. Description of the Related Art Generally, a radiator of an automobile is a real car.
As disclosed in Japanese Patent No. 114729, a vibration system is configured by elastically supporting a radiator with respect to a frame on the body side, and a body damper at the time of idling operation is damped by a dynamic damper effect due to the vibration of the radiator. Is being done

The structure for supporting the radiator will be described with reference to FIG. 3. The lower portion of the radiator 1 is supported by a lower frame 2 which is laid across the lower portion of the body in the width direction through an elastic body 3 made of a rubber member. Further, the upper portion of the radiator 1 is arranged at a rear position of the upper frame 4 installed on the upper portion of the body, and the protrusion 5 provided on the upper portion of the radiator 1 is inserted into the holding hole formed at the rear end of the bracket 6 via the elastic body 7. The bracket 6 is connected to the upper surface of the upper frame 4 by bolts 8. The lower frame 2 and the upper frame 4 are joined to each other by a support member 9 at a substantially central portion.

[0004]

However, in the conventional radiator supporting structure as described above, the front end of the bracket is bolted to only the upper surface of the upper frame having a substantially inverted U-shaped cross section. Therefore, if a large thrust force is applied to the radiator due to riding over the projection on the road surface,
As shown by an imaginary line in FIG. 3, the upper frame may be deformed and the upper holding portion or the lower supporting portion of the radiator may come off. As a countermeasure, it is necessary to increase the plate thickness of the upper frame and attach a reinforcing plate, which causes a problem of increasing weight and cost. The present invention aims to solve these conventional problems with an extremely simple structure.

[0005]

In order to achieve the above object, the present invention provides that the bracket is arranged below the upper frame and the front end of the bracket is connected to a front flange of the upper frame bent downward. The rear end edge of the upper frame is brought into contact with and supported by the upper surface of the intermediate portion between the coupling portion and the radiator holding portion.

[0006]

In the radiator support structure configured as described above, since the thrusting force of the radiator is received by both the bracket and the upper frame member, the upper frame is prevented from being deformed and the intermediate portion of the bracket is prevented. Since it is pressed by the rear edge of the upper frame, the bending moment is reduced and the bracket itself is less likely to be deformed. Therefore, even if a large thrusting force is applied, it is possible to prevent the holding portion in the upper portion of the radiator or the supporting portion in the lower portion from coming off. Further, since it is not necessary to increase the plate thickness of the upper frame or attach a reinforcing plate, there is an effect that problems such as an increase in weight and a cost can be eliminated.

[0007]

The present invention will be described below with reference to the illustrated embodiments. FIG. 1 is a first embodiment of the present invention, which is a radiator 1
The upper part of 0 is located at the rear of the upper frame 11 provided in the width direction on the upper part of the body and is held by the upper frame 11 via the bracket 12. The bracket 12
Is formed so as to have a crank-shaped cross section, is arranged below the upper frame 11, and connects the front end 12a to the front flange 11a of the upper frame 11 bent downward by tightening the bolt 13 while A holding hole 14 is provided at the rear end, and the holding hole 14 allows the pin-shaped projection 15 provided on the upper surface of the radiator 10 to project into the elastic body 1.
It is elastically held via 6. Then, the rear end edge 11b of the upper frame 11 is brought into contact with the upper surface of the bracket 12 which is an intermediate portion between the connecting portion 17 of the bracket 12 and the upper frame 11 and the holding portion 18 of the radiator 10. The abutting portion is configured such that the rear end edge 11b of the upper frame 11 is bent downward and pressed against the vertical wall 12b formed in the crank-shaped bent portion of the bracket 12.

FIG. 2 shows a second embodiment of the present invention. In this embodiment, the lower end of the front flange 11a of the upper ram 11 bent downward is bent further forward to form a horizontal flange 11c. The front end 12a of the flat plate-shaped bracket 12 is connected to the horizontal flange 11c by tightening bolts 13, while the rear end edge 11b of the upper frame 11 is provided on the upper surface of the bracket 12 between the connecting portion 17 and the holding portion 18 of the radiator 10. Abut. The other structure is the same as that of the first embodiment.

In the first and second embodiments, the thrust force of the radiator is applied to the bracket 12 and the upper frame 1.
Since it is received by both members of No. 1, the rigidity against the thrust force of the radiator is significantly improved. Therefore, since it is not necessary to increase the plate thickness of the upper frame 11 or attach a reinforcing plate, there is no problem such as an increase in weight and a cost. Furthermore, in the first embodiment, the upper frame 11 and the bracket 12 form a closed square cross section, and the rear edge 11b of the upper frame 11 is formed.
Is pressed against the vertical wall 12b of the bracket 12, so that the closed cross section does not collapse even when the thrusting force from the radiator 10 acts. Therefore, as compared with the case where the rear end edge 11b of the upper frame 11 is simply brought into contact with the upper surface of the bracket 12, the rigidity with respect to the thrusting force of the radiator 10 can be further increased.
