[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a damper device using a radiator in which components mounted around the radiator are effectively used as a damper to reduce vibration of a vehicle body.

[0002]

2. Description of the Related Art A conventional arrangement in an engine room will be described with reference to FIG. 5. A cooling system component is mounted on a front side (front end) of an engine room R, and its structure is arranged at a front end side. A condenser 1 is provided, a radiator 2 is provided on the rear side, and a fan shroud 3 is further provided on the rear side. Further, the fan shroud 3 and the radiator 2 are integrated by bolts, and the condenser 1
Is separately provided from the radiator 2, or the capacitor 1 is integrated with the radiator 2 by bolts. The receiver dryer 4 is attached to a wall surface in the engine room R with a bolt 6 via a bracket 5. Battery 7, engine 8,
The transmission 9 schematically shows each position. Japanese Patent Application Laid-Open No. 9-196513 discloses that a receiver dryer is attached to a fan shroud in order to reduce the number of steps for assembling a cooling system component to a vehicle.
Further, an integrated fan shroud and condenser is disclosed.

[0003]

In the engine room, large heavy equipment such as an engine, a transmission and a battery are preferentially arranged in consideration of the weight balance of the entire vehicle body, and the space around these equipment is given priority. , Various other components are mounted, and therefore, the mounting density of the various components is high in the engine room.
For these reasons, the arrangement positions of various components in the engine room are often restricted. The radiator is
It is generally mounted on a vehicle body in a floating state and used as a damper to reduce vibration of the entire vehicle body. In this floating state, the radiator is supported by multiple mounts,
When the radiator is used as a damper, the weight of the radiator is not evenly distributed to each mount on the left and right,
If the mount is biased, the radiator will vibrate in a complicated manner due to the different elastic modulus of each mount.

The above-mentioned restrictions on the disposition positions of the various components in the engine room R are not exceptional in the installation of the fan shroud 3 which is a cooling system component in FIG. 5, so that the radiator 2 and the fan shroud are restricted due to space restrictions. Even when the radiator 3 is integrated, it may be necessary to integrate the radiator 2 with the center of gravity of the fan shroud 3 being shifted. As described above, when the two and three are integrated with the center of gravity shifted, the center of gravity of the combined weight of the two and three is shifted with respect to the mount support supporting the radiator 2. In addition, the weight of the combined weight is not evenly distributed between the left and right mounts. As a result, the combined weight vibrates in a complicated manner, making it difficult for the radiator 2 to function sufficiently as a damper. In some cases, the weight resonates with the vibration of the vehicle body, which is disadvantageous. is there.

In order to solve this problem, the center of gravity of the combined weight is located at the center of the mount support so that the weight of the combined weight is evenly distributed to a plurality of mounts supporting the radiator 2. To determine the position, but in the engine room where the mounting density is high,
It is practically difficult to determine the mount support position at the optimum position, and the calculation of the vibration system becomes complicated due to many uncertain factors, which causes a problem in reliability.

In FIG. 5, when the fan shroud 3, the radiator 2, and the condenser 1 are integrally connected, similarly, the center of gravity of the combined heavy object integrating the three supports the radiator. And the weight of the combined weight is not evenly distributed between the left and right mounts, resulting in the same problem as described above.

Further, as disclosed in Japanese Patent Application Laid-Open No. 9-196513, when a receiver dryer is provided integrally with a fan shroud for the purpose of reducing the number of assembling steps on site, the radiator is supported. It is clear that the center of gravity of the combined weight is further deviated from the mount support that is mounted, and even if the radiator functions as a damper, it will vibrate complicatedly and cannot be used as a damper. There is a problem that it is inconvenient due to resonance with vibration.

Accordingly, the present invention provides a method of making the center of gravity of a combined weight integrally connected to a radiator coincide with the center of gravity of the radiator alone, or equalizing the weight of the combined weight to each mount supporting the radiator. The present invention provides a damper device in which the combined weight is reliably functioned as a damper against vibration of the vehicle body.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, an outline will be described with reference to FIG. FIG. 2 shows a condenser 1 and a radiator 2
And the radiator 2 are integrally connected by a bolt 10, but the present invention is not limited to this type, and a type in which the capacitor 1 and the radiator 2 are not integrally connected may be used. A cooling fan 11 is integrally attached to the radiator 2 with a bolt 18 via a fan shroud 3. The fan motor 12 has a large weight and the center of gravity coincides with the cooling fan 11. The radiator 2 is supported by a vehicle body via a mount 13. The support of the radiator 2 by the mount 13 is such that the weight of the radiator 2 is equally distributed to the four mounts 13 on the left and right sides. The receiver dryer 4 attaches the bracket 14 fixed to the receiver dryer 4 to the fan shroud 3.
The receiver dryer 4 is fixed to the fan shroud 3 by fixing it to the bracket 15 fixed to the fan shroud 3 with bolts 16.

As shown in FIGS. 3 and 4, in the engine room R where the mounting density is high, the center of gravity of the cooling fan 11 (the fan motor 12) and the center of gravity of the radiator 2 are made to coincide with each other. May not be fixed. That is, as shown in FIG. 1, the center of gravity G2 of the cooling fan 11 may be shifted from the center of gravity G1 of the radiator 2 by L1. Therefore, the receiver driver 4 is moved so that the center of gravity G3 of the receiver dryer 4 is separated from the center of gravity G1 of the radiator 2 by L2.
Is attached to the fan shroud 3 so that the center of gravity of the radiator 2, the cooling fan 11 (fan motor 12) and the receiver dryer 4 integrally joined is positioned on the vertical center line C1 passing through the center of gravity G1 of the radiator. To the fan shroud 3.

The embodiment shown in FIG. 1 shows an example in which the center of gravity G1 of the radiator 2 is located at the position of L3 which is half the width of the radiator 2 (that is, on the center line C1 of the radiator 2). Since the center of gravity G1 of the radiator 2 is not always on the center line C1, it is not limited to this embodiment. The mount 13 supporting the radiator 2 is disposed so that the weight W of the radiator 2 acting on the center of gravity G1 of the radiator 2 is evenly distributed to the left and right. In this embodiment, since the lower two mounts 13 are heavily weighted in the stationary state, each lower mount 13 is weighted by W / 2. Therefore, the mounting position of the receiver dryer 4 is set so that the center of gravity of the radiator 2 and the cooling fan 11 (fan motor 12) and the receiver dryer 4 integrated with each other is on the center line between the left and right mounts 13 supporting the radiator 2. After determining L2 in FIG. 1, the receiver dryer 4 is attached to the fan shroud 3, and the weight (W + W1 + W2) of the radiator 2, the cooling fan 11 (fan motor 12) and the receiver dryer 4 integrally combined is determined by a plurality of values. It is distributed equally to the left and right to the mount 13.

In the above description, the type in which the condenser 1 and the radiator 2 are not integrated has been described, but the same applies to the case where the two are integrated. That is, the condenser 1 and the radiator 2 are integrated, and the radiator 2
Cooling fan 11 via fan shroud 3
(Fan motor 12) is attached integrally, and the radiator 2 is supported on the vehicle body by the mount 13. Then, as shown in FIG. 1, the condenser 1, the radiator 2, the cooling fan 11 (fan motor 12), and the receiver dryer 4
L2 is determined so that the center of gravity integrating the two is on the vertical center line C1 passing through the center of gravity G1 of the radiator, and the receiver dryer 4 may be attached to the fan shroud 3.

Alternatively, the dimensions of the condenser 1, the radiator 2, the cooling fan 11 (fan motor 12), and the center of gravity of the receiver dryer 4 may be aligned with the center line between the left and right mounts 13 supporting the radiator 2. L2 is determined, and the receiver dryer 4 is attached to the fan shroud 3 such that the total weight of the condenser 1, the radiator 2, the cooling fan 11 (fan motor 12), and the receiver dryer 4 is evenly distributed to the mount 13 on the left and right sides. In this embodiment, the receiver dryer 4 includes the brackets 14 and 15 and the bolt 1.
Although it is fixed to the fan shroud 3 through 6, the fixing method is not limited to this.

Next, the operation of the damper device using the radiator of the present invention will be described. FIG. 3 shows the engine room R of a mini vehicle, and FIG. 4 shows the engine room R of a large vehicle. The engine 8, the transmission 9, and the battery 7 are preferentially arranged in consideration of the weight balance of the entire vehicle. In the mini vehicle shown in FIG. 3, these heaviest heavy objects are arranged so as not to contact the struts 17. Subsequently, the position of the mount 13 is determined so that the radiator 2 is arranged at the most appropriate position and the weight of the radiator 2 is equally distributed to the mount 13 on the left and right sides. The fan shroud 3 is fixed to the radiator 2 with bolts 18 in FIG. 2 so that the fan shroud 3 does not come into contact with the engine 8, the battery 7 and the like in a state where the radiator 2 is arranged at the most optimal position. Therefore, depending on the fixed position of the fan shroud 3, as shown in FIG. 1, the center of gravity G1 of the radiator and the fan shroud 3 (fan motor 1)
The center of gravity G2 of 2) may be shifted by the dimension L1.

Then, the receiver dryer 4 is attached to the fan shroud 3 and when the three members 2, 3, 4 are integrally connected, the receiver is so arranged that the center of gravity of the combined weight coincides with the center of gravity G 1 of the radiator 2. The mounting position L2 of the dryer 4 is determined, and before the components are mounted in the engine room R, the components are mounted in advance. When the condenser 1 is integrally assembled with the radiator 2, the center of gravity of the combined weight when the fan shroud 3 (fan motor 2), the radiator 2, the condenser 1, and the receiver dryer 4 are integrally combined with each other is determined by the radiator 2. The mounting position L2 of the receiver dryer 4 is determined so as to coincide with the center of gravity G1 of the receiver, and the receiver dryer 4 is assembled in advance outside the engine room R. As described above, by assembling the cooling system components outside the engine room R in advance, the number of components to be assembled in the engine room R in a limited space can be reduced, and the efficiency of assembly can be improved.

By fixing the cooling system components such that the center of gravity of the combined weight coincides with the center of gravity G1 of the radiator 2, the bias of the center of gravity of the combined weight can be prevented. Similarly, a predetermined mount 13 (mount mounting portion 1 shown in FIG.
By determining the mounting position L2 of the receiver dryer 4 such that the center of gravity of the combined weight is located at the center between 9), the weight of the combined weight can be evenly distributed to the mounts 13 on the right and left sides.

Further, priority is given to the position of the fan shroud 3 which affects the cooling performance of the radiator 2 and the condenser 1,
In addition, priority is given to the arrangement of the fan shroud 3, the radiator 2, and the condenser 1, which occupy a large volume in the engine room R, and the mounting position of the receiver dryer 4, which occupies a small volume in the engine room R, satisfies desired conditions. By determining later, the bias of the center of gravity of the combined weight is prevented, or the weight of the combined weight is evenly distributed to the mounts 13 supporting the radiator 2. And capacitor 1
Can be maintained, and assembly into the narrow engine room R can be facilitated.

[0026]

As described above in detail, according to the first aspect of the present invention, the center of gravity of the combined weight in which the radiator, the cooling fan, and the receiver dryer are integrally combined,
The center of gravity of the mounted radiator alone can be matched. As a result, the bias of the center of gravity can be prevented, so that the combined weight can reliably function as a damper against vibration of the vehicle body.

Next, according to the second aspect of the present invention, the weight of the combined weight in which the radiator, the cooling fan, and the receiver dryer are integrally combined is substantially equally distributed to each of the mounts supporting the radiator. As a result, the combined weight can reliably function as a damper against vibration of the vehicle body.

According to the third aspect of the present invention, the center of gravity of the combined weight in which the condenser, the radiator, the cooling fan, and the receiver dryer are integrated can be made to coincide with the center of gravity of the mounted radiator alone. As a result, it is possible to prevent the center of gravity from being biased, so that the weight of the combined weight can be evenly distributed to the left and right, and the combined weight can reliably function as a damper against vibration of the vehicle body.

Finally, according to the fourth aspect of the present invention,
The weight of the combined weight, which integrally combines the condenser, radiator, cooling fan, and receiver dryer, is distributed almost equally to the left and right mounts supporting the radiator. It can reliably function as a damper.
