BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for an air cleaner disposed in an engine room.

[0002]

2. Description of the Related Art FIG. 4 shows an example of a supporting structure of an air cleaner for an automobile. In the figure, reference numeral 5 denotes an air cleaner, and upper brackets 16 extending in the horizontal direction are fixed to three portions of the outer wall 5a. Reference numeral 7 denotes an apron panel in the engine room of the automobile. An L-shaped lower bracket 18 extending toward the lower side of the upper bracket 16 is fixed to the side wall 7a. A body mount 1 for supporting the air cleaner 5 is provided between the upper bracket 16 and the lower bracket 18.
1 is interposed. The body mount 11 is a compression type and mainly includes a substantially cylindrical vibration-proof rubber 12.
The sleeve 13 is integrated with the hollow part. A peripheral groove 12a is formed in the center of the outer periphery of the vibration isolating rubber 12, and a hole 16a of the upper bracket 16 is engaged with the peripheral groove 12a.

When the air cleaner 5 is mounted, a bolt 14 is inserted into the sleeve 13 of the vibration isolating rubber 12, and a nut 14 a is screwed into a threaded portion projecting from a hole of the lower bracket 18. At this time, the anti-vibration rubber 12 is initially in a state of bulging in the vertical direction of the sleeve 13, but is compressed by tightening the nut 14 a so that both end surfaces of the sleeve 13 and the upper and lower surfaces of the anti-vibration rubber 12 are flush. Become. Thus, the air cleaner 5 is properly supported at three points and is stably held.

[0004]

However, the above-described structure for supporting the air cleaner has a problem that the vibration-proof effect is not sufficiently exhibited. That is, the mounting positions of the lower bracket 18 provided on the side wall 7a of the engine room of the automobile and the upper bracket 16 provided on the air cleaner 5 may be shifted due to dimensional variations at the time of manufacturing and tolerances of products. When the nut 14a is tightened to the bolt 14 inserted into the sleeve 13, the bolt 14
There are places where the parts are fastened in an inclined state. Then, due to the inclination of the sleeve 13, a part of the anti-vibration rubber 12 is pinched and hardened, resulting in a decrease in the ability to absorb vibration, thereby significantly reducing the anti-vibration effect.

An object of the present invention is to solve the above problems.

[0006]

According to the present invention, in order to solve the above-mentioned problems, a support piece having a screw shaft protruding upward in the axial direction and a bolt hole in a protruding portion protruding to one side are provided. A plurality of body mounts extending from the air cleaner are formed by integrally mounting the support pieces provided and the support pieces and a solid rubber bush located in the middle between the support pieces and the support pieces. wherein a bracket, that the respective interposed between the respective bracket extending from the engine room side wall located below entered into the body mount between the two brackets by using the bolt hole and the threaded shaft And

[0007]

When the air cleaner is attached to the side wall of the engine room of the automobile at, for example, three points by using the body mount of the present invention, first, the screw shaft of the body mount is inserted into the bolt hole of one bracket and fixed. Then, the protruding portion is to be aligned with the bolt hole of the other bracket. At this time, if the pitch does not match due to deviation of the pitch, the protrusion is aligned with the two holes of the other bracket by using the slight deformation of the rubber bush in the torsion direction, and the bolt nut is inserted and fastened here. . At this time, since the protruding portion of the support piece protrudes to one side, it is easy to insert the bolt by matching the deviation of the pitch. In addition, since the fastening operation at this time is an operation of fixing the protruding portion to the other bracket, the twist due to the rotation of the nut does not act on the rubber bush, and the rubber bush is twisted to cause a crack. No more.

Further, since the body mount has a solid rubber bush interposed between the upper and lower supporting pieces, the weight of the air cleaner can be stably supported by its compressive stress and the shearing direction can be improved. It is possible to form a body mount having a large volume and excellent vibration absorption properties against vibrations, and the vibration isolation effect can be enhanced. Further, since the air cleaner can be attached and detached from above, the maintainability is good even in a small engine room.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view showing a support structure of an air cleaner according to the present invention.

The air cleaner 5 is configured to be supported on an apron panel 7 in an engine room by using three body mounts.

The body mount 1 has a rubber bush 4 integrally connected between the upper support piece 2 and the lower support piece 3. The upper support piece 2 has a circular shape, and a bolt screw shaft 2 a protruding in the axial direction of the rubber bush 4 is fixed to the center portion. The lower support piece 3 has a substantially rectangular shape, and a bolt hole 3c is provided in a protrusion 3b that protrudes from the base end 3a to one side.

The rubber bush 4 has a columnar shape with a small diameter at the center portion.
The lower surface is fixed to the base end 3a by vulcanization bonding. As a result, the two support pieces 2 and 3 are arranged in a vertical positional relationship, and the large volume body mount 1 mainly made of rubber is formed.

As shown in FIG. 2, the air cleaner 5 has two upper brackets 6 fixed to one side wall 5a and one upper bracket 6 on a side wall 5b adjacent thereto.
Are fixed (see FIG. 3). These upper brackets 6 have a flat plate shape and extend outwardly from the side walls 5a and 5b, and are provided with a screw shaft insertion hole 6a on the tip end side.

On the side wall 7a of the apron panel 7, 2
The lower bracket 8 integrally formed with the protruding pieces is fixed, and the lower bracket 9 is also fixed to the side wall 7b on the suspension side. These lower brackets 8,
Reference numeral 9 denotes an L-shaped cross section, which extends horizontally from each of the side walls 7a and 7b and has a bolt hole 8a at the tip end.

Next, mounting of the air cleaner 5 will be described.

When the air cleaner is supported at, for example, three points, first, the screw shaft 2a of the body mount 1 is inserted into the screw shaft insertion hole 6a of the upper bracket 6 and fixed with the nut 2b. Next, the protruding portions 3b are to be aligned with the bolt holes 8a of the lower brackets 8, 9, respectively. At this time, the lower bracket 9
If the bolt hole (not shown) does not match the bolt hole 3c of the protrusion 3b, the protrusion 3b and the holes 8a of the lower brackets 8 and 9 are formed by utilizing the slight deformation of the rubber bush 4 in the torsion direction. Insert bolt 10 and nut 10a
To conclude. At this time, since the protruding portion 3b of the lower support piece 3 protrudes to one side, it is easy to insert the bolt 10 by matching the deviation of the pitch.

[0018]

[Effects of the Invention] As described above, when the air cleaner is supported at, for example, three points by using the body mount of the present invention,
Even if the bolt holes do not match due to the pitch deviation, the rubber bushing is flexible and the protruding part of the support piece protrudes to one side, so insert the bolt after matching the pitch deviation. It is easy to fasten with nuts,
Work efficiency is improved. In addition, since the rotational force at the time of fastening the nut when fixing the protrusion of the support piece protruding to the one side to the bracket does not act on the rubber bush, the rubber bush is not twisted and cracks are generated, and the body is not generated. There is an effect that the mount can be maintained for a long life and the air cleaner can be supported in a stable state.

Further, since the body mount has a solid rubber bush interposed between the upper and lower support pieces, the weight of the air cleaner can be stably supported by the compressive stress, and the shear direction can be improved. It is possible to construct a body mount having a large volume and excellent vibration absorption properties against vibrations, and there is also an advantage that a vibration-proof effect can be enhanced. Further, since the air cleaner can be attached and detached from above, the maintainability is good even in a small engine room.
