Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiator mounting structure mounted on an automobile.

[0002]

2. Description of the Related Art Conventionally, as a device for attaching a radiator to a vehicle member, a structure in which it is attached to a vehicle member via a bracket in a tank made of brass or resin is generally used. For example, the conventional radiator shown in FIG.
The bracket 2 integrally formed with the inclined plate 2a is soldered.

The conventional radiator shown in FIG. 10 fixes the bracket 2 to the tank 1 by inserting the bolt 3 into the bolt hole 2b of the bracket 2 in the side plate 1b formed at the end of the tank 1 and tightening the nut 4 into the tank 1. Is. In the conventional radiator shown in FIG. 11, when the tank 1 is mounted on the vehicle-side member 5, the rubber portion 7 of the bracket 6 is fitted and fixed to the tank 1 and the bracket 6 is attached to the vehicle-side member 5 by the bolt 8 inserted into the bolt hole 9. It is something that is fixed.

[0004]

However, in the prior art shown in FIGS. 9 and 10, the difference in thermal expansion is large due to the difference in the materials of the tube 10 and the bracket 2 which constitute the radiator core portion, so that the tube 10 has a large difference in thermal expansion. There is a problem that a crack due to thermal stress is likely to occur at the root of the end, and if this crack occurs, water leakage in the tank 1 occurs. For example, as shown in FIG. 12, the end portion 1 of the tube 10 of the radiator core portion formed by the tube 10 and the fins 11 is formed.
0a is inserted into a plate 12a forming the lower surface of the tank 1, and the plate 12 and the tube 10 are fixed by a tube root 13 around the end 10a. In the tube root portion 13, a crack is generated due to the difference in the amount of elongation displacement due to the difference in thermal expansion between the bracket 2 and the tube 10, that is, the difference in thermal expansion between the bracket 2 and the tube 10, and water leakage occurs from this cracked portion.

Further, in the conventional radiator shown in FIG. 11,
If it is attempted to reduce the height of a radiator mounted in front of the vehicle in order to meet the recent demand for slant nose of the vehicle bonnet, there is a problem that the mounting space for the bracket 6 becomes insufficient. The present invention has been made to solve such a problem, and an object of the present invention is to provide a radiator mounting structure capable of absorbing heat distortion of a radiator and mounted in a small space above and below the radiator. To do.

[0006]

A radiator mounting structure according to the present invention for achieving the above object comprises a first uneven portion formed on a tank portion of a radiator and a second uneven portion formed on a bracket on a vehicle body side. And an elastic member having a first convex / concave portion and a second convex / concave portion that can be fitted in correspondence with the first concave / convex portion and the second concave / convex portion.

[0007]

According to the radiator mounting structure of the present invention, since the elastic member having the fitting portion is mounted between the tank portion of the radiator and the vehicle-side member, the radiator core portion is arranged in the tube length direction. The elastic member absorbs the strain and the strain in the lengthwise direction of the vehicle-side member. Therefore, it is possible to prevent thermal distortion caused by differences in materials, temperature distribution, etc. of the radiator and its fixture, damage to the radiator due to vibration from the vehicle, water leakage and the like. Moreover, it is possible to secure the radiator to the vehicle-side member while ensuring a small margin space above and below the tank portion of the radiator.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. (First Embodiment) A first embodiment of the present invention is shown in FIGS. In the radiator 20, the tubes 10 and the fins 11 forming the core portion are alternately arranged between the upper tank 1 and the lower tank 15. On the flat surface 1c of the upper tank 1, a pin projection 16 protruding upward is projected,
The flat surface 15c is provided with a pin protrusion 17 protruding downward.

A rubber mount 21 is attached to the pin protrusions 16 and 17.
The insertion hole 28 of 22 is inserted. This rubber mount 2
Grooves 27 are formed on the entire circumference of the outer peripheral portions of Nos. 1 and 22. The U-shaped groove 30b of the bracket 30 is fitted into the groove portion 27 of the rubber mounts 21 and 22. Bracket 30
Is provided so that the side plate 30d faces the frame portions 37 and 38 of the side plate 36 of the core portion. A flat plate 30a is formed on the upper and lower ends of the side plate 30d, and a U-shaped groove 30b is formed on the flat plate 30a.
Are formed. Bolt holes 33 and 34 are formed in a mounting side plate 30c that is bent in a direction perpendicular to the side plate 30d. Bolts 31, 32 are inserted into these bolt holes 33, 34.
Is inserted, and the bracket 30 is screwed and fixed to the vehicle-side member 35. The width L of the mounting side plate 30c is the vehicle side member 3
It is longer than the width of No. 5. Lower tank 1
The same applies to the case where the bracket 30 is fixed via the rubber mount 22 inserted into the pin protrusion 17 of No. 5.

When assembled, the upper tank 1 of the radiator 20 is
Rubber mount 2 on the pin protrusions 16 and 17 of the lower tank 15.
Insert the insertion holes 28 of 1, 22 into the rubber mounts 21, 2
The U-shaped groove 30b of the bracket 30 is sandwiched and fixed in the groove 27 of No. 2, then the bolts 31 and 32 are inserted into the bolt holes 33 and 34 of the bracket 30, and these bolts 31 and 32 are fastened and fixed to the vehicle side member 35. .

According to the first embodiment, when there is a difference in the amount of expansion and contraction in the longitudinal direction of the tubes 10 and fins 11 forming the core portion and the amount of expansion and contraction in the longitudinal direction of the bracket 30,
Position of groove 27 of rubber mounts 21 and 22 and U-shaped groove 30
Absorption due to thermal strain is performed by moving the position with b. Also,
Since the rubber mounts 21 and 22 are used, the vibration transmitted from the vehicle-side member 35 via the bracket 30 is absorbed by the rubber mounts 21 and 22, so that the vibration applied to the radiator 20 is reduced. Further, since the upper and lower tanks 1 and 15 have a structure in which the vertical mounting space is small, there is an advantage that it is easy to cope with the slant nose of the vehicle in which the radiator 20 is mounted. Furthermore, since the width L of the mounting side plate 30c of the bracket 30 can be arbitrarily determined, the vehicle side member 35
The bracket 30 serves as a seal for preventing hot air from flowing between the radiator 20 and the radiator 20. Therefore, it is not necessary to separately provide a seal member for preventing the hot air from flowing between the vehicle-side member 35 and the radiator 20, and there is an effect that the structure is simple.

In the above structure, the pin projection 16 and the insertion hole 28 of the rubber mount 21, the groove portion 27, and the U-shaped groove 30b have a dimensional relationship such that the rubber mount 21 and the bracket 30 can be freely moved for ease of assembly. The size may be fixed or fixed, and the size can be selected arbitrarily. Regarding the width L of the mounting side plate 30c of the bracket 30, when the bracket 30 is used as a means for sealing the gap between the vehicle-side member 35 and the radiator 20, the width L is set to an arbitrary width L that can prevent hot air from flowing around.
The size can be selected.

Since the radiator 20 is in an environment where it is repeatedly subjected to temperature changes, rubber mounts 21 and 22 made of elastic members and a bracket 30 for mounting the radiator are provided so as to absorb the load of the temperature change. By interposing it between the radiator core portions, the extension of the radiator core portion is absorbed, and the stress generated at the base portion of the tube 10 is reduced. Therefore, damage and destruction of the base portion of the tube 10 are prevented, and water leakage and the like are prevented. Can be prevented.

Since the conventional separate parts required to prevent the hot air flowing around between the radiator 20 and the vehicle-side member 35 are omitted and the bracket 30 for mounting can be substituted for the hot air circumvention preventing member, the number of parts and the number of mounting steps are increased. The effect of reducing is great. (Second Embodiment) Next, a second embodiment of the present invention is shown in FIGS. An example of another shape of the rubber mount is shown in FIGS. 3 and 4.
