Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a radiator support structure for supporting and fixing a radiator used for heat radiation of engine cooling water to the body of an automobile.

As shown in FIG. 1, the radiator is constructed by interposing seat plates 4 and 5 above and below a core part 3 consisting of a large number of liquid passage pipes 1, 1 and fins 2, 2, respectively, to form an upper tank having an inlet pipe 6. A lower tank 9 having an outlet pipe 8 is connected and fixed thereto. The radiator configured in this manner is used while being supported and fixed within the engine room of an automobile.

Conventionally, in order to support and fix the radiator to the vehicle body 11, as shown in FIGS. 1 and 2, side brackets 10 having an L-shaped cross section are provided on both left and right sides of the core part 3 and connected to the upper and lower tanks 7 and 9. , 10, or as shown in FIGS.
At the same time, the flat side brackets 10a, 10a and the vehicle body 11 are placed on the L-shaped metal fittings 1.
4 and 14, and the side bracket 10
This was done by connecting the upper parts of the a and 10a and the vehicle body with connecting rods 15 and 15.

However, in the conventional radiator support structure as described above, the left and right sides of the radiator are supported and fixed to the vehicle body separately, so the vibrations of the vehicle body transmitted to the left and right sides of the radiator are different, and the radiator may be subject to twisting, etc. Due to the added stress, failures such as water leakage were likely to occur.

The present invention aims to eliminate the drawbacks of the conventional structure and provide a radiator support structure that reduces undue stress on the radiator, reduces failures such as water leakage, and increases the durability of the radiator. It is.

Hereinafter, the present invention will be explained with reference to drawings showing embodiments.

FIG. 5 shows a bracket 16 used in the support structure of the present invention. The bracket 16 is attached to the upper half 1
7 and a lower half 18. Each of the members 17 and 18 is formed by bending a metal plate having a long U-shaped cross section so that the entire body is roughly U-shaped, and has two parts on both sides of the lower end of the upper half part 17 and on both sides of the upper end of the lower half part 18. Flat mounting flanges 19, 19 are formed facing outward, respectively.
20 is a hole drilled in each mounting flange 19; 21;
is a bead for reinforcing each mounting flange. The upper half 17 and the lower half 18 are formed to have approximately the same size and shape, but the water supply port 22 (Fig. 1) on the upper surface of the upper tank of the radiator is inserted into the upper surface of the upper half 17. A hole 23 is bored therein.

In order to fix the radiator to the vehicle body using the bracket 16 configured as described above, as shown in FIGS. The radiator is held by the bracket 16 with an elastic material 24 such as rubber interposed between the upper surface of the lower half section 18 and the lower surface of the lower tank 9, and the mounting flange 19 of the upper half section 17 is The mounting flange 19 of the lower half part 18 is brought into contact with the upper surface of the horizontal part 11a of the vehicle body, and the horizontal part 11a is held between the mounting flanges 19, 19 of both halves. The radiator is fixed to the vehicle body via the bracket 16 by tightening the bolt 25 and nut 26.

In this way, since the entire radiator is supported and fixed to the vehicle body by the bracket 16, even if the left and right horizontal parts 11a, 11a to which the radiator is fixed vibrate differently, No stress such as twisting is applied to the radiator. Furthermore, since the elastic material 24 is interposed between the bracket 16 and the radiator, the vibrations of the vehicle body are less transmitted to the radiator, and the radiator is less fatigued by vibrations.

The structure for attaching the bracket 16 to the horizontal portion 11a of the vehicle body is as shown in FIG. 6 above.
In addition to the structure in which the horizontal part 11a is held between the mounting flange 19 of the upper half part 17 and the mounting flange 19 of the lower half part 18, as shown in FIG.
It is also possible to have a structure in which the parts 9 and 19 are attached to each other so as to overlap each other on the upper surface (or lower surface) of the horizontal part 11a. Furthermore, the mounting flange 19 and the horizontal portion 11a
If an elastic material such as rubber is interposed between the radiator and the radiator, it is possible to more effectively prevent vibrations of the vehicle body from being transmitted to the radiator.

The radiator support structure of the present invention is configured and operates as described above, so that no excessive force is applied to the radiator due to vibrations of the vehicle body.
The durability of the radiator can be improved. In addition, the entire radiator has a U-shaped cross section, and a bracket 16 is comprised of an upper half 17 and a lower half 18, each of which has a U-shape.
Since the radiator is held by the radiator, side brackets and the like of the radiator can be omitted, and the radiator can be supported reliably and the structure can be simplified, which has great practical effects.
