Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a vehicle intake resonator.

2. Description of the Related Art In an automobile, a resonator is branched and connected to an intake duct to reduce intake noise.

The mounting structure of the resonator will be described with reference to FIGS.

As shown in FIG. 4, the resonator 1 is an engine room 2
It is branched and connected to the intake duct 3 routed therein, and is disposed in the space 6 between the hood ridge panel 4 and the fender panel 5 shown in FIGS. Reference numeral 7 denotes an air cleaner.

The intake duct 3 is supported on the hood ridge panel 4 by a rubber mount 8 from the engine room 2 side. On the other hand, the resonator 1 inserts a rubber mount 10 into a fork-shaped mounting portion 9 formed on the front and rear sides thereof. mount
10 is fastened and supported to the hood ridge panel 4 by stud bolts 11 and nuts 12 penetrating from the space 6 side. Reference numeral 13 denotes a groove into which the mounting portion 9 of the resonator 1 is inserted, and reference numeral 14 denotes a bolt insertion hole (a similar structure is disclosed in, for example, Japanese Utility Model Laid-Open No. 60-187359).

However, in the above-described conventional intake resonator mounting structure, in order to secure the insertion length L of the stud bolt 11, the width of the resonator 1 must be adjusted between the hood ridge panel 4 and the fender panel 5. It must be set to be smaller by L than the space 6 between them, and there is a problem that the capacity of the resonator 1 is reduced by that amount.

In order to mount the resonator 1, the space 6
It is necessary to insert the stud bolt 11 into the mounting hole 15 (shown in FIG. 9) of the hood ridge panel 4 from the inside, and there is a problem that the operation is difficult.

Therefore, the present invention provides a mounting structure for an automobile intake resonator, which can ensure a sufficient capacity of the intake resonator and facilitates the mounting operation.

Means for Solving the Problems In a mounting structure of an automotive intake resonator, which is branched and connected to an intake duct provided in an engine room and is provided in a space between a hood ridge panel and a fender panel, The mounting material is mounted on the mounting portion of the vehicle, and the engaging portion of the mounting material is engaged with the hood ridge panel. The mounting material of the intake duct is fastened to the mounting material together with bolts from the engine room side.

Function By supporting the intake resonator and the intake duct in the same part of the hood ridge panel, installation efficiency is improved,
The mounting members of the intake resonator and the intake duct are fastened together by bolts from the engine room side to facilitate the work, and the working space is not required in the space, thereby increasing the capacity of the intake resonator.

An embodiment of the present invention will be described below with reference to the drawings.

1 to 3, a resonator 16 serving as an intake resonator is provided in an intake duct disposed in an engine room 17.
18 and is disposed in a space 21 between the hood ridge panel 19 and the fender panel 20 as in the conventional case. Incidentally, reference numeral 22 denotes an air cleaner.

Here, a fork-shaped mounting portion 23 is formed on the front and rear side edges of the resonator 16 as in the related art, and a mounting portion 24 is also formed on the corresponding intake duct 18.

A first rubber mount 25 as a mounting material is mounted on the mounting portion 23 of the resonator 16, while a second rubber mount 26 is also mounted on the mounting portion 24 of the intake duct 18. Rubber mount 25
And the second rubber mount 26 are fastened together by bolts 27 from the engine room 17 side.

Specifically, as shown in FIGS. 1 and 2, the first rubber mount 2
5 is provided with a screw hole 28 at the center thereof into which the bolt 27 is screwed, a groove 29 into which the mounting portion 23 of the resonator 16 is inserted into a peripheral wall thereof, and a locking portion which engages with the mounting hole 30 of the hood ridge panel 19. The locking groove 31 is formed. Here, reference numeral 32 denotes a head of the first rubber mount 25 protruding toward the engine room 17, and the head 32 protrudes toward the engine room 17 by a dimension l (l <L).

On the other hand, the second rubber mount 26 has an insertion hole for the bolt 27.
A groove 34 into which the mounting portion 24 of the intake duct 18 is inserted is formed, and a hood ridge panel is formed.
A concave portion 35 for receiving the head 32 of the first rubber mount 25 is formed on the end surface on the 19th side.

 In addition, 36 indicates a color and 37 indicates a washer.

In mounting the resonator 16 of the above embodiment, first, the groove 29 of the first rubber mount 25 is inserted into the mounting portion 23 of the resonator 16, and the first rubber mount 25 is mounted on the resonator 16. Similarly, the second rubber mount 26 is attached to the attachment portion 24 of the intake duct 18.

Next, the heads 32 of the first rubber mounts 25 are inserted into the mounting holes 30 of the hood ridge panel 19, and the first rubber mounts 25 are mounted.
Is fitted into the mounting hole 30.

At this time, the protrusion l of the head 32 of the first rubber mount 25
Is sufficiently smaller than the stroke L of the conventional stud bolt, the width of the resonator 16 may be set closer to the rear surface of the fender panel 20.
Can be sufficiently secured.

Then, a recess 35 of the second rubber mount 26 attached to the air duct 18 is mounted on the head 32 of the first rubber mount 25.
The second rubber mount 26 of the intake duct 18 is brought into contact with the mounting portion of the first rubber mount 25 by inserting the bolt 27 through the washer 36, and the first rubber mount 25 is inserted. And the second rubber mount 26 together.

Here, since the first rubber mount 25 and the second rubber mount 26 can be fastened together by the bolt 27, the operation is improved, and the watertightness at the mounting portion of the first rubber mount 25 and the second rubber mount 26 is enhanced. .

Then, as a result, the intake duct 18 and the resonator 16 vibrate as the same mass, so that the resonance frequency can be reduced.

Note that the present invention is not limited to the above-described embodiment. For example, the number of support points of the intake duct and the resonator may be one or three.

Effect of the Invention As described above, according to the present invention, the intake resonator can be attached from the engine room side, so that the working space in the space between the hood ridge panel and the fender panel can be reduced, Therefore, most of the space can be used as a space for arranging the intake resonator, and there is an effect that a large capacity of the resonator can be secured.

Further, since the mounting material of the intake duct is fastened to the mounting material of the intake resonator together with the mounting material from the engine room side, there is an effect that the mounting operation is easy to perform.
