Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a radiator mounting structure for cooling an engine.

(Prior Art) Conventionally, a radiator used for an automobile engine or the like is provided with bolt holes at four positions on the upper, lower, left and right sides, and these four positions are fixed by bolts, as shown in Japanese Utility Model Laid-Open No. 58-33728. This allowed it to be attached to the vehicle body in a stable condition.

When the radiator is directly attached to the vehicle body as described above, there is a problem that vibrations on the vehicle body side are directly transmitted to the radiator and the radiator core is easily damaged.
For this reason, recently, a rubber is interposed between the radiator and the vehicle body to absorb the vibration transmitted from the vehicle body.

However, even with the above mounting structure, depending on how the radiator is mounted, the vibration absorbing direction of the rubber and the vibration direction of the vehicle body do not match, and the rubber interposed between the radiator and the vehicle body works effectively. In some cases, the vibrations transmitted from the vehicle body could not be completely absorbed. Moreover,
With the mounting structure as described above, the vibration directly transmitted from the vehicle body can be absorbed to some extent, but the vibration indirectly transmitted through the bolt cannot be absorbed. Moreover, since the bolt, the radiator and the vehicle body were in metal contact with each other, the bolt and the radiator collided with each other due to the vibration, and noise was generated.

Further, in the mounting structure as described above, in order to mount the radiator on the vehicle body without rattling, it was necessary to securely fix the upper, lower, left and right four places with bolts.
For this reason, it is necessary to secure a sufficient space for assembly in the engine room where the radiator is assembled so that the hands and the like can be thrust into the interior of the engine room. However, the parts were densely housed in the engine room, and such a space could not be secured. For this reason, it is difficult to fix the two lower left and right positions located deep inside the engine room because other parts interfere with the operation. Further, in the above-mentioned mounting structure, it is necessary to specially provide a means for temporarily holding the radiator so that it is not necessary to fix the heavy radiator by bolts while holding it by hand at the time of assembly. there were.

As a structure for attaching a radiator via a rubber mount, there is also known a structure as disclosed in Japanese Patent Laid-Open No. 59-202937. In this structure, a leg portion extending downward is provided at the lower end of the radiator, the leg portion is fitted to a rubber mount having a T-shaped cross section and a vertical hole at the center, and the rubber mount is provided on a flange portion of a vehicle body panel. The lower part of the radiator is attached to the vehicle body by press-fitting into the mounting hole, and the upper part of the radiator is attached to the vehicle body panel with a bolt via a rubber mount. However, even with this structure, the above rubber mount may not be able to absorb the vibration sufficiently, and with the rubber mount attached to the lower end of the radiator, press it while aligning it with the mounting hole in the flange part of the vehicle body panel. The work to do is not easy.

(Purpose of the Invention) The present invention reduces the transmission of vibration from the vehicle body, reduces the noise generated due to the vibration, and allows the radiator to be mounted on the vehicle body in a stable state and the work of assembling the radiator. In particular, it is not necessary to provide a special means for temporarily holding the radiator during assembly, and the stability of the radiator during assembly work is ensured to facilitate assembly work. It is an object of the present invention to provide a radiator mounting structure for an engine that enables the above.

(Construction of the Invention) The present invention is a radiator mounting structure that is mounted on a vehicle body.
In a substantially horizontal direction, and while a mounting member consisting of a rod extending in the front-rear direction of the radiator and a rubber covering the surface thereof is provided, a holder is fixed to each location corresponding to both sides of the radiator lower part of the vehicle body, The holder has a width substantially corresponding to the length of the mounting member in the front-rear direction, and is formed in a hook shape having an upward opening portion for inserting and removing the mounting member. The gist of the invention is that both sides of the lower portion of the radiator are attached to the vehicle body through the holders by being inserted and held from above, and the upper portion of the radiator is fixed to the vehicle body through the rubber through bolts.

According to the above configuration, since the upper and lower portions of the radiator are attached to the vehicle body via the rubber, even if the vehicle body vibrates, the vibration is absorbed by the rubber, and the plate member having elasticity on the lower side of the radiator is also installed. Vibration is also absorbed by the above-mentioned holder and is hardly transmitted to the radiator. Moreover, since the mounting member provided on the lower part of the radiator is held by the holder provided on the vehicle body, it is not necessary to fix the lower part of the radiator with bolts, and the holder is opened upward by the elastic plate material. The hook-shaped member simplifies the work of fitting the mounting member into the holder.

In particular, when the radiator is assembled, the holder temporarily holds the radiator by holding the attachment members on both sides of the lower portion of the radiator, and at this time, the above-mentioned attachment member having a rod extending in the front-rear direction of the radiator as a shaft portion. Is held by a holder that has a width in this direction,
Even before the upper part of the radiator is fixed, the radiator does not tilt in the front-rear direction and is stably held.

(Embodiment) FIGS. 1 and 2 show an embodiment of a radiator mounting structure for an engine according to the present invention. In these drawings, reference numeral 1 denotes a radiator, which is arranged between side frames (a part of the vehicle body) 2 and 2. Reference numeral 3 denotes a radiator shroud (a part of the vehicle body), which is arranged in front of the radiator 1. The radiator shroud 3 is shown in FIG. 1 and the side frames 2, 2 are omitted in FIG.

As shown in the figure, the radiator 1 has a predetermined shape in the front and rear, and in order to reinforce the radiator core 1a, the tanks 1b and 1c arranged above and below the radiator core 1a, and the radiator core 1a. The radiator core 1a includes side brackets 1d and 1e arranged on both sides and fixed to the tanks 1b and 1c. The side brackets 1d and 1e are composed of a base plate portion 11 along the radiator core 1a and upright portions 12 and 13 which stand up from both front and rear sides thereof laterally. A bolt hole 15 is formed in one of the upright portions 12 on the upper side of the side brackets 1d and 1e. Also, the side brackets 1d, 1
A mounting member 14 is provided between the upright portions 12 and 13 in the lower part of e. The mounting member 14 is substantially horizontal and extends in the front-rear direction of the radiator, and both ends thereof are cylindrical rods 14a integrally attached to the upright portions 12 and 13, and the rod 14a.
And a rubber 14b that covers the surface of the.

Bolt holes 15 formed on the top of the side brackets 1d, 1e
A bolt 16 is passed through the bolt 16, and the bolt 16 is screwed into a nut 17 welded to the radiator shroud 3. Thereby, the upper part of the radiator 1 is fixed so as not to move with respect to the radiator shroud 3. A rubber 18 is interposed between the upright portion 12 and the radiator shroud 3 in the bolt 16 insertion portion, and even if the radiator shroud 3 vibrates, the vibration is absorbed by the rubber 18 and transmitted to the radiator 1. Vibration is designed to be reduced.

Clips (holders) 21 are attached to the mounting plates 22 on the side frames 2 and 2 corresponding to the both sides of the lower part of the radiator of the vehicle body.
It is attached integrally via. Clip 21
As shown in FIGS. 3 and 4, it is formed by bending a plate material having elasticity into a hook shape. A mounting member 14 is fitted in the loop portion 21a of the clip 21. To fit the mounting member 14 into the loop portion 21a,
The mounting member 14 is positioned above the open portion 21b of the loop portion 21a, and the mounting member 14 is pushed toward the open portion 21b. With this configuration, the opening portion 21b is expanded by the pushing force, and the mounting member 14 passes through the opening portion 21b and is fitted into the loop portion 21a.

In order to stably hold the mounting member 14 fitted in the loop portion 21a, the mounting member 14 has a width B substantially corresponding to the length of the mounting member 14 in the radiator front-rear direction at the root portion of the loop portion 21b. In addition, the width A of the end portion of the loop portion 21a is made smaller than the width B of the root portion so that the mounting member 14 can easily pass through the open portion 21b when the mounting member 14 is fitted. The mounting member 14 fitted in the loop portion 21a is sandwiched by the loop portion 21a by the elasticity of the clip 21 and cannot be easily separated from the inside of the loop portion 21a. In this way, the mounting member 14 is held by the clip 21, and thereby fixed to the lower portion of the radiator 1 so as not to move with respect to the side frames 2, 2. Even if the side frames 2 and 2 vibrate, the vibration is absorbed by the rubber 14b and the clip 21 due to the damping ability of the rubber 14b and the flexibility of the clip 21, so that the vibration is hardly transmitted to the radiator 1. Has become.

As described above, according to this radiator mounting structure, the upper and lower portions of the radiator 1 are mounted on the vehicle body (side frames 2, 2).
And the radiator shroud 3) is fixed so as not to move. For this reason, radiator 1
Can be attached to the vehicle body in a stable state without rattling.

Moreover, the rubber 14b and the clip 21 of the mounting member 14 are interposed between the vehicle body and the radiator 1 in the lower mounting portion, and the rubber 18 is interposed in the upper mounting portion, so that the vehicle body vibrates. Even if you do, the vibration is rubber
It is absorbed by 14b, 18 and the clip 21, and is hardly transmitted to the radiator 1. In particular,
Since the mounting member 14 is completely covered with the rubber 14b at the lower mounting portion, vibration is generated via the halt as compared to the case where both the upper and lower mounting portions of the radiator are fixed to the vehicle body via the rubber via bolts. Therefore, the transmission of vibrations from the vehicle body can be reduced without being transmitted. At the same time, since the mounting member 14 is completely covered with the rubber 14b, metal contact does not occur between the radiator and the vehicle body at the lower mounting portion, and noise generated due to vibration can be reduced.

Further, according to this mounting structure, the mounting member 14 provided at the lower portion of the radiator 1 is held by the clip 21 and the radiator 1 is temporarily held by the side frames 2, 2, and then the upper portion of the radiator 1 is held. By fixing the radiator shroud 3 with the bolts 16, the radiator 1 can be attached to the vehicle body (side frames 2, 2 and the radiator shroud 3). Since it is only necessary to hold the mounting member 14 to the clip 1 at the lower mounting portion in this manner, it is not necessary to poke a hand etc. into the interior of the engine room, and a sufficient space for assembly can be secured in the engine room. Even without the radiator 1, the radiator 1 can be easily assembled.

Moreover, since the radiator 1 is temporarily held by the side frames 2 and 2 by fitting the mounting member 14 into the clip 21 before bolting the upper portion of the radiator 1, the radiator is temporarily held. There is no need to provide a special means to store it. Further, the mounting members 14 formed so that the axial portions of the rods 14a are oriented in the front-rear direction of the radiator on the left and right sides of the lower portion of the radiator 1 are held by the clips 21 having a width in this direction. Even when the radiator 1 is temporarily held, the radiator 1 is stably held without tilting back and forth, and the work of bolting the upper portion of the radiator 1 becomes easy.

The engine radiator mounting structure according to the present invention is not limited to the above-described embodiment. As shown in FIG. 5, a flange portion 14c made of rubber 14b may be formed at both ends of the mounting member 14. By doing so, the radiator 1 does not move in the directions of the arrows C and D in the figure, and the radiator can be attached to the vehicle body in a more stable state. Although the holder is attached to the vehicle body via the attachment plate in the above-described embodiment, it may be attached directly to the vehicle body.

(Effects of the Invention) In the radiator mounting structure of the engine according to the present invention, a mounting member made up of a rod extending in a substantially horizontal direction and in the front-back direction of the radiator and a rubber covering the surface is provided on both sides of the lower portion of the radiator. This attachment member is held by a hook-shaped holder provided in the vehicle body and having a width in the front-rear direction of the radiator, and the upper portion of the radiator is fixed to the vehicle body by a bolt via rubber. . Therefore, it is possible to reduce the transmission of vibrations from the vehicle body, reduce the noise generated due to the vibrations, and improve the workability of assembling the radiator. Especially, since the mounting member is inserted and held from the upper side in the hook-shaped holder having the upward opening portion, the mounting member can be easily fitted and, by this, the radiator upper part at the time of assembling. The radiator can be held temporarily before fixing, and it is not necessary to provide a special means for holding the radiator, and the radiator can be held stably during this temporary holding. This makes it very easy to fix the radiator. Further, in the mounted state, the mounting member does not accidentally separate from the holder, and the radiator mounted state can be reliably maintained.
