Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an improvement of a mounting device for engine-related parts such as an air cleaner and a silencer.

(Prior art) For example, air cleaners, which are one of the engine-related parts, come in two types: one is a so-called carburetor mount that is mounted on the carburetor, and the other is a so-called chassis mount that is mounted on the bottom wall or side wall of the engine room. However, as shown in Fig. 3, the chassis mount type generally has a base plate b made of metal or synthetic resin placed on the upper surface of a vibration-isolating rubber annular body a of a required thickness, and a flanged nut c on the lower surface. A plurality of bracket members B are fitted and abutted, and their contact surfaces are vulcanized and bonded using an adhesive, and a base plate B is attached to the bottom wall or side wall of the air cleaner body A.
are fixed by spot welding or the like, and the air cleaner body A is placed in a predetermined position on the chassis panel P, and the bolt d is screwed into the nut c from the outside of the panel P so that the air cleaner body A is elastically mounted on the chassis. ing.

By the way, the air cleaner main body A mounted on the chassis as described above may sometimes separate from the bracket member B during use and become unusable.

This is thought to be due to the following reasons.

(Problem to be solved by the invention) Normally, at the stage where a plurality of bracket members B are fixed to the air cleaner body A, the surface of the air cleaner body A is painted and then baked and dried before installation on the chassis. However, during the drying process, the adhesive used to bond the rubber annular body a of the bracket member B to the base plate b or the flanged nut c deteriorates and becomes brittle due to the influence of heating above 150°C. It is thought that this is caused by vibrations from the engine and other sources that cause peeling.

Therefore, this invention is an attempt to eliminate the above-mentioned inconveniences, and even if engine-related parts such as air cleaners are exposed to heat during the manufacturing process or usage conditions, they can be used for long periods of time without fear of peeling. The purpose of the present invention is to provide a mounting device for engine-related parts that can withstand high temperatures.

(Means for Solving the Problems) In order to achieve the above object, this invention is a cylindrical body made of metal or synthetic resin and having an outward flange at the upper end and an inward flange for preventing slippage at the lower end. A rubber annular body having a through hole in the center and an annular recess in the center of the through hole, the outer diameter and height of which are approximately equal to the inner diameter and height of the cylindrical body, is inserted into the inside of the cylindrical body. A nut with a flange is inserted into the through hole of this rubber annular body and its flange is engaged with the annular recess to form a bracket member, and this bracket member is inserted into the case body through the outward flange of the cylindrical body. It is fixed to the outer wall and screwed to the flanged nut from the outside of the chassis panel.

(Function) Since this device has the above-mentioned configuration, the rubber annular body and the nut with flanges are fitted into the inside of the cylindrical body and integrated by engaging the flange of the nut with the annular recess, and the outside of the cylindrical body is integrated. It is fixed to the outer wall of the case body via the facing brim to securely attach it to the chassis panel, so even if a tensile force is applied to the mounting device due to vibration, the problem of peeling of the adhesive portion does not occur.

(Embodiment) An embodiment of this invention will be described with reference to FIGS. It has a wide outward facing flange 1a for fixing, and an inward facing flange 1b for preventing slipping off at the lower end. Reference numeral 2 denotes an annular rubber body for vibration isolation, the outer diameter d and height h of which are formed approximately equal to the inner diameter x and height y of the cylindrical body 1, and a nut member 3 with a flange is fitted in the center. The lower end is formed to have a smaller diameter by the thickness of the cylindrical body 1, and forms a locking step 2b of the inward flange 1b at the lower end of the cylindrical body.
An annular recess 2c having a diameter approximately halfway between the outer diameter d and the inner diameter is formed in the center of the inner diameter. 3 is a nut with a flange made of metal or synthetic resin, and the rubber annular body 2
A threaded cylindrical portion 3a whose lower end slightly protrudes from the lower end of the rubber annular body 2 when inserted into the through hole 2a engages with an annular recess 2c in the center of the through hole 2a. It is formed by the collar 3b.

4 is a bolt for fastening that is screwed into the nut 2.

Therefore, the above-mentioned bracket member B can be formed by press-fitting rubber into a mold set in advance on the cylindrical body 1 and the flanged nut 3 and vulcanizing it to integrally mold it, or by using a previously molded rubber annular body 2. After assembling the nut 3 and the cylindrical body 1, they are vulcanized and formed.

A plurality of these bracket members B are fixed by spot welding or screwing, with the outward flange 1a of the cylindrical body 1 abutting against the outer wall of the air cleaner main body 1.

At this stage, the air cleaner body A is painted and baked if necessary.

Thereafter, the air cleaner main body A that has undergone the necessary processing is placed at a predetermined position on the chassis panel P.
A bolt 4 is screwed into the flanged nut 2 from the outside of the panel P, and the air cleaner body A is fixed as shown in FIG.

In addition, in the above example, the cylindrical body 1, the rubber annular body 2,
Although the annular recess 2c and the flanged nut 3 are shown as having a circular shape, they are not limited to this, and may have a square or other non-circular cross section. It can also be applied to engine-related parts such as air ducts and mufflers.

(Effects of the invention) As described above, in this invention, the cylindrical body 1, the rubber annular body, and the flanged nut constituting the bracket member are made to fit into each other instead of being butted and glued together as in the conventional case. Even if the case body is heated and dried while the members are attached to the case body, or even if a considerable amount of heat is applied during use, there is no fear that the parts will peel off and fall off and can withstand long-term use.
