Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a support device for elastically supporting a radiator with respect to a vehicle body, and particularly to the structure of a vibration isolating rubber thereof.

(Prior Art) Conventionally, in a passenger car, a radiator having a relatively large weight is elastically supported in a floating state on a vehicle body via a vibration isolating rubber in order to absorb vibration of the vehicle body during idling operation. To function as a vibration damping mass body.

By the way, the anti-vibration rubber that elastically supports this radiator is
It is divided into a compression type and a shearing type depending on how the load is received, and it is desirable to reduce the spring constant in both cases from the viewpoint of damping vehicle body vibration.

However, since the anti-vibration rubber that supports the lower part of the radiator has a larger shared load than the anti-vibration rubber that supports the upper part of the radiator, it is necessary to consider not only the spring constant but also the point of durability. As the conventional anti-vibration rubber, a highly durable compressed type is often used.

(Problems to be solved by the invention) However, although the compression type anti-vibration rubber is excellent in terms of durability, the hardness of the rubber itself may be lowered or the peripheral surface of the anti-vibration rubber may be reduced in order to reduce the spring constant. It was necessary to make this anti-vibration rubber easy to bend, for example, by forming a notch in it. For this reason, the original durability is sacrificed, and the spring constant is naturally limited, and there is room for further improvement in terms of damping vehicle body vibrations.

Therefore, according to the present invention, sufficient durability can be obtained while lowering the spring constant, the vehicle body vibration can be reliably damped by using the radiator, and the spring constant and durability of the anti-vibration rubber can be set. It is an object of the present invention to provide a radiator supporting device having an increased degree of freedom.

[Constitution of device]

(Means for Solving the Problems) Therefore, in the present invention, the radiator is provided with an anti-vibration rubber that supports the upper part and the lower part of the radiator in a floating state. The anti-vibration rubber that supports the main body that is compressed from above and below between the radiator and the vehicle body and the outer peripheral surface of the main body portion are provided so as to project radially in a diagonally downward direction, and the tip end thereof is on the vehicle body side. It is characterized in that it is composed of a plurality of connected arm portions.

(Operation) According to this structure, the vibration-proof rubber that supports the lower portion of the radiator receives the weight of the radiator as a compressive load because its main body is vertically compressed between the radiator and the vehicle body.
At the same time, the arms are vertically deformed between the main body and the vehicle body and receive the weight of the radiator as a shear load.When vibrations from the vehicle body are transmitted to this anti-vibration rubber, Respectively deforms to support the radiator in a floating state. In particular, according to the above configuration, the vibration damping rubber arms are projected radially obliquely downward, and the main body is supported from below by these arms, so that the arms use the weight of the radiator as a shear load. Not only can it be received as a compressive load to some extent. Therefore, the weight of the radiator added to the main body is
It is possible to effectively transmit to the vehicle body side through the arm portion, and as compared with the case where the arm portion extends horizontally, the arm portion does not bend downward more than necessary, and the vibration isolation is accordingly increased. The durability of rubber is improved.

Also, since the arm portion that receives most of the weight of the radiator as a shear load extends radially and is more easily deformed than the main body portion, it is possible to elastically support the radiator in a floating state,
As described above, the radiator can be effectively used as a vibration damping mass body while ensuring the durability of the vibration damping rubber itself.

Therefore, the weight of the radiator can be efficiently received as a compressive load and a shear load, and it is possible to achieve both improved durability of the anti-vibration rubber and a low spring constant.

Moreover, by appropriately changing the angle of inclination of the arm portion with respect to the main body portion in accordance with the weight of the radiator, when the weight of the radiator is added to the antivibration rubber, the compression amount and the shear amount of the arm portion can be changed. .

Therefore, the spring constant and durability of the anti-vibration rubber can be relatively easily changed according to the weight of the radiator.

(Embodiment) The present invention will be described below based on an embodiment shown in the drawings.

The radiator indicated by reference numeral 1 in the drawing is installed at the front end of the engine room of a passenger car, and an upper tank 3 for guiding cooling water from the engine is installed above the core 2 of the radiator 1. A lower tank 4 is attached to a lower portion of the core 2, and cooling water cooled in the process of passing through the core 2 is collected in the lower tank 4, and the cooling water is returned to the engine side through an outlet pipe 5. Sent.

By the way, such a radiator 1 is provided between the front upper member 6 and the front lower member 7 which form the vehicle body.
It is elastically supported in a floating state. That is, between the upper surface of the upper tank 3 and the front upper member 6, and between the lower tank 4 and the front lower member 7, a vibration-proof rubber structure 8 is provided.
The anti-vibration rubber structure 8 is provided with anti-vibration rubber 9, 10 that contacts the upper surface of the upper tank 3 and the lower surface of the lower tank 4. The outer peripheral surfaces of the anti-vibration rubbers 9 and 10 are fixed to the inner peripheral surface of a tubular mounting member 11 by means of baking or the like. The mounting member 11 is attached to the front upper member 6 and the front lower member 7. Are linked to. The upper surface of the upper tank 3 and the lower tank 4 are inserted into the fitting holes 12 formed in the central portions of the vibration-proof rubbers 9 and 10.
A support pin 13 protrudingly provided on the lower surface of the radiator 1 is fitted therein, and the radiator 1 is elastically supported in a floating state by the fitting with respect to the front upper member 6 and the front lower member 7.

By the way, the anti-vibration rubber 10 on the lower tank 4 side that receives the weight of the radiator 1 is configured as follows in order to reduce the spring constant thereof while ensuring durability.

That is, as shown in FIG. 2, the anti-vibration rubber 10 has a cylindrical main body 15 at the center thereof. The upper surface of the main body 15 is in contact with the lower surface of the lower tank 4, and a hollow hole at the center of the main body 15 constitutes the fitting hole 12. Body 1
On the outer peripheral surface of 5, there are integrally provided four arm portions 16 that project radially in a diagonally downward direction. The tips of the arm portions 16 are fixed by baking onto the inner peripheral surface of the mounting bracket 11. There is.

According to such a configuration, the radiator 1 having a relatively large weight is elastically supported in a floating state on the vehicle body via the anti-vibration rubbers 9 and 1. Therefore, for example, when the vehicle body vibrates during idling operation, the radiator 1 is separated from the vehicle body. Vibrates independently,
This vibration of the car body is offset.

At this time, a vibration-proof rubber 10 supporting the lower tank 4 of the radiator 1 is attached to the lower surface of the lower tank 4, and a cylindrical main body portion 15 is attached to the outer peripheral surface of the main body portion 15 and a mounting member fixed to the vehicle body side. Since it is configured with four arms 16 that radially connect with 11, the body part 15 of this anti-vibration rubber 10 receives the weight of the radiator 1 as a compressive load, and the arm part 16 is attached to the body part 15. It deforms vertically with the metal fitting 11 and receives the load of the radiator 1 as a shear load.

That is, when the vibration from the vehicle body is transmitted to the anti-vibration rubber 10,
Since the body portion 15 and the arm portion 16 are respectively deformed, the single vibration-proof rubber 10 has both the conventional compression type and shearing type functions.

Since the arm portions 16 of the anti-vibration rubber 10 are provided so as to project obliquely downward from the main body portion 15 and support the main body portion 15 from below, the four arm portions 16 are The weight of the radiator 1 can be received not only as a shear load but also as a compressive load to some extent.

Therefore, the weight of the radiator 1 added to the main body 15 is
The vibration can be transmitted to the front lower member 7 through the arm portion 16, and the arm portion 16 does not bend excessively downward as compared with the case where the arm portion 16 extends horizontally. The durability is improved.

Moreover, the arm portion 16 that receives much of the weight of the radiator 1 as a shear load is more easily deformed than the main body portion 15 that receives a compressive load, and when vibration of the vehicle body is transmitted, the arm portion 16 is deformed in the vertical direction to float the radiator 1. Since the elastic rubber is elastically supported, the spring constant of the anti-vibration rubber 10 can be reduced despite the durability of the anti-vibration rubber 10 itself being secured as described above. Therefore, the radiator 1 can be effectively used as a vibration damping mass body, which helps reduce vehicle body vibration.

Therefore, the load of the radiator 1 can be efficiently received as a compressive load and a shear load, and it is possible to improve the durability of the antivibration rubber 10 and achieve a low spring constant at the same time.

Moreover, if the angle of inclination of the arm portion 16 with respect to the main body portion 15 is appropriately changed according to the weight of the radiator 1, the anti-vibration rubber 1
When the load of the radiator 1 is applied to 0, its arm 16
It is possible to change the amount of compression and the amount of shear.

Therefore, there is an advantage that the spring constant and durability of the vibration-proof rubber 10 can be changed relatively easily according to the weight of the radiator 1.

In the above embodiment, the tanks are attached to the upper and lower parts of the core, but the present invention is not limited to this, and a radiator having tanks on the left and right sides of the core may be used.

[Effect of device]

According to the present invention described in detail above, when vibration from the vehicle body is transmitted to the anti-vibration rubber, the main body and the arm are respectively deformed, and a single anti-vibration rubber is used for both the conventional compression type and the shearing type. In addition to having a function, the arm part is shaped to support the body part from below, so that the plurality of arm parts can not only receive the weight of the radiator as a shear load but also as a compressive load to some extent. it can.

Therefore, the weight of the radiator can be transmitted to the vehicle body through the arm portion, and the arm portion does not bend excessively downward as compared with the case where the arm portion extends horizontally. The durability is improved.

Moreover, when the vibration of the vehicle body is transmitted, the arms are deformed in the vertical direction to elastically support the radiator in a floating state, so the vibration-proof rubber spring is secured despite its durability. The constant can be lowered. From this, the weight of the radiator can be efficiently received as a compression load and a shear load, and it is possible to achieve both improved durability of the anti-vibration rubber and a low spring constant.

Moreover, according to the above configuration, if the angle of inclination of the arm portion with respect to the main body portion is appropriately changed according to the weight of the radiator, when the load of the radiator is applied to the antivibration rubber, the compression amount and the shear amount of the arm portion are reduced. Since it can be changed, there is also an advantage that the spring constant and durability of the anti-vibration rubber can be changed relatively easily according to the weight of the radiator.
