Abstract
The utility model discloses a kind of denoising device of motor head, it comprises gear chamber, pad and bolts on, wherein, described gear chamber front end is provided with denoising device, described denoising device is by the fixing sound-isolating sponge of plastic cover plate, and described sound-isolating sponge, plastic cover plate shape match with described gear chamber cover.The beneficial effects of the utility model are: by installing the denoising device be made up of sound-isolating sponge and plastic cover plate in the gear chamber front end of motor, and the noise solving the generation of gear chamber front end is comparatively large, thus causes the problem that whole engine noise is larger; And structure is simple, easy to install; Easy to manufacture, cost of production is low.
Description
Technical field
The utility model relates to engine components, particularly relates to a kind of denoising device of motor head.
Background technique
Along with improving constantly of Automobile Design level and production technology, the usability of different brands automobile and the difference of Safety performance more and more less.By contrast, the travelling comfort of automobile just becomes the key factor distinguishing automobile quality.Automobile storage is in NVH (noise, vibration, travelling comfort) problem, and particularly commercially product sold, if problem solves not in time, can affect the market share of Products.For this reason, need to carry out noise reduction optimization to each system of whole motor, workload is very large, the construction cycle is long and cost is high.The noise produced due to gear transmission account for major component in whole engine noise, can effectively reduce the noise of gear transmission generation to external diffusion, thus effectively reduce the total noise of centrifuge of motor by installing denoising device additional in gear chamber front end.
Model utility content
The purpose of this utility model is the denoising device providing a kind of motor head, to solve because the noise of gear chamber front end generation is comparatively large in prior art, thus causes the problem that whole engine noise is larger, and structure is simple, easy to install, easy to manufacture, cost of production is low.
For reaching this object, the utility model by the following technical solutions:
A denoising device for motor head, it comprises gear chamber, pad and bolts on, and wherein, described gear chamber front end is provided with denoising device, and described denoising device is by the fixing sound-isolating sponge of plastic cover plate.
Especially, described sound-isolating sponge, plastic cover plate are arranged on outside the gear chamber cover of described gear chamber front end, and described sound-isolating sponge, plastic cover plate shape match with described gear chamber cover.
Especially, described sound-isolating sponge is pressed on described gear chamber cover by described plastic cover plate, and by described pad, bolt on fixing.
Especially, the material of described sound-isolating sponge is polyurethane, and the material of described plastic cover plate is Nylon-66 reinforced with glass fiber.
The beneficial effects of the utility model are, the denoising device of described motor head is by installing the denoising device be made up of sound-isolating sponge and plastic cover plate in the gear chamber front end of motor, the noise solving the generation of gear chamber front end is comparatively large, thus causes the problem that whole engine noise is larger; And structure is simple, easy to install; Easy to manufacture, cost of production is low.
Accompanying drawing explanation
Fig. 1 is the denoising device scheme of installation of the motor head that the utility model embodiment 1 provides;
Fig. 2 is the structural representation of sound-isolating sponge;
Fig. 3 is the structural representation of plastic cover plate.
In figure:
1, gear chamber; 2, gear chamber cover; 3, denoising device; 31, sound-isolating sponge; 32, plastic cover plate; 4, pad; 5, bolt on.
Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
Refer to described in Fig. 1 to Fig. 3, in the present embodiment, a kind of denoising device of motor head, it comprises gear chamber 1, pad 4 and bolts on 5, wherein, gear chamber cover 2 arranged outside of described gear chamber 1 front end has denoising device 3, described denoising device 3 comprises sound-isolating sponge 31 and plastic cover plate 32, described sound-isolating sponge 31 is pressed on described gear chamber cover 2 by plastic cover plate 32, and by described pad 4, bolt on 5 fix, described sound-isolating sponge 31, plastic cover plate 32 shape match with described gear chamber cover 2.
The material of described sound-isolating sponge 31 is polyurethane, and the material of described plastic cover plate 32 is Nylon-66 reinforced with glass fiber.
Described sound-isolating sponge 31 in use, is first pressed on described gear chamber cover 2 by plastic cover plate 32 by the denoising device of described motor head, and by described pad 4, bolt on 5 fix; Normal ato unit again, the noise produced due to gear chamber 1 account for major component in whole engine noise, the use of the denoising device 3 of gear chamber 1 front end can effectively reduce the noise of gear chamber 1 to external diffusion, thus effectively reduces the total noise of centrifuge of motor.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model does not limit by above-mentioned example; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various change and change, and these changes and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
