Abstract

(57) [Summary] [Purpose] To improve durability by reliably damping the vibration input from the engine to the intercooler. [Structure] In a vehicle in which an intercooler is arranged between the engine hood and the engine, a vibration damping member that elastically contacts both the intercooler and the engine hood with the engine hood closed is provided between the intercooler and the engine hood. Provide and secure a large number of anti-vibration support points for the intercooler.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an anti-vibration support structure for an intercooler for cooling pressurized intake air from a turbocharger.

[0002]

[Prior art and problems to be solved]

 There are many conventional intercoolers that support vibration isolation via rubber mounts, as disclosed in, for example, Japanese Utility Model Laid-Open No. 1-173335, but the conventional one is that the intercooler flange and the engine-side mounting flange are There is a problem that the vibration of the intercooler cannot be sufficiently prevented because it is only a structure in which a rubber washer is interposed between the two and it is tightened with a bolt.

Particularly when the intercooler is supported above the engine of the vehicle, vibration of the engine not only acts directly on the intercooler, but also the position and number of mounting fulcrums are limited, which makes it difficult to prevent vibration. The durability of the intercooler was likely to be impaired.

The present invention has been made in view of such conventional problems, and an object thereof is to improve the durability by surely damping the vibration input from the engine to the intercooler. ..

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, in the present invention, in a vehicle in which an intercooler is arranged between the engine hood and the engine, both the intercooler and the engine hood are closed between the intercooler and the engine hood. An anti-vibration member that elastically contacts with is provided.

[0006]

With the above structure, not only is the intercooler supported on the engine, but also the engine hood is vibration-isolated and supported by the vibration-proof member. A large number are secured, vibration transmission is effectively mitigated, and durability is improved.

【Example】

 1 or 2, 1 is an intercooler, 2 is a mounting flange portion provided at four corners of the intercooler, 3 is a rubber washer attached to the upper and lower surfaces of the mounting flange portion 2, and 4 is a mounting flange portion 2. The intercooler mounting portion (see FIG. 2) provided at the upper part of the engine as described above, 5 is a bolt for fastening the inner cooler 1 together with the rubber washer 3 to the mounting portion 4, and 6 is an engine hood of the vehicle. ..

In this embodiment, as a vibration damping member provided between the engine hood 6 and the intercooler 1, as shown in the figure, a suction cup 8 is provided upward on an arm portion 7 extending from the upper four corners of the intercooler 1. Further, on the back surface of the engine hood 6, a liner member 10 having a smooth smooth portion 9 is attached so that the suction cup 8 is surely attracted.

The liner member 10 is formed with an air introduction passage 11 so as to open to each smooth portion 9, and a valve 12 for opening and closing each air introduction passage 11 is provided. The valve 12 is normally closed and can be opened by remote control from the outside or the vehicle interior. For example, each passage 11 may be opened to the atmosphere when an operation of opening the engine hood 6 is performed in conjunction with an unlocking mechanism (not shown) of the engine hood 6.

Based on the above configuration, the intercooler 1 is not only supported by the mounting portion 4 through the rubber washer 3 on the engine side, but also when the engine hood 6 is closed as shown in FIG. Since the suction cup 8 is brought into close contact with the smooth portion 9 of the liner member 10, the suction cup 8 is also elastically supported by the engine hood 6. For this reason, the number of vibration-proof supporting points of the intercooler 1 is increased, and a reliable vibration-proof function is obtained accordingly.

On the other hand, in order to open the engine hood 6 from the state shown in FIG. 2, the valve 12 is opened beforehand. Since the atmosphere is introduced between the suction cup 8 and the smooth portion 9 when the valve 12 is opened, the liner member 10 is easily separated from the suction cup 8 and therefore the engine hood 6 can be opened without any trouble. If the valve 12 is opened in cooperation with the unlocking mechanism of the engine hood 6 as described above, it is not necessary to separately perform the operation for detaching the suction cup 8 from the liner member 10, which is more practical. improves.

Although this embodiment shows an example in which the suction cup 8 is provided as a vibration isolating member, the invention is not limited to this, and a rubber or a spring may be applied as the vibration isolating member.

[Effect of the device]

 According to the present invention, a substantial vibration-damping supporting point is provided between the intercooler and the engine hood by providing a vibration-damping member that elastically contacts both the intercooler and the engine hood when the engine hood is closed. Since many are secured, it is possible to reliably suppress the vibration of the intercooler and improve its durability.
