The utility model discloses an outlet duct subassembly can reduce the noise of a plurality of frequency channels of engine, has good noise cancelling effect, can also reduce air intake system and occupy the space in the cabin, solve the limited and nervous problem in the numerous spaces of bringing of part in warpout under -deck space.
Description
Technical field
The utility model relates to a kind of engine aspirating system steam outlet pipe assembly.
Background technique
Gas handling system (Airintakesystem) is mainly used in the field such as pneumatic machinery, diesel machine, its effect is for these machinery provide clean air, prevent these machinery from sucking the probability increasing abrasion and damage with the air of impurity particle at work, thus raising engine life, and it is more abundant to make motor fire fire, improves motor Economy.Gas handling system mainly comprises air filter assembly, suction tude assembly and steam outlet pipe assembly, and wherein, air filter assembly comprises filter core and housing, and filter core is filter element, carries the filtration work of gas, and housing is for filter core provides the external structure of necessary protection.Suction tude assembly guides dirty air in air filter assembly, and dirty air-filtering is become cleaned air by the filter core in air filter assembly, and then cleaned air is inducted in motor by steam outlet pipe assembly.Because motor car engine burning and inflow noise are comparatively large, usually at gas handling system outer installment sound attenuation features, to reduce noise.Because sound attenuation features is arranged at outside, therefore, there is large, that erasure effect the is poor defect that takes up room in existing gas handling system.
Model utility content
The technical problems to be solved in the utility model is large, that erasure effect the is poor defect that takes up room existed to overcome prior art, provides a kind of engine aspirating system steam outlet pipe assembly.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of engine aspirating system steam outlet pipe assembly, its feature is, it comprises a upper cover and a lower cover, is provided with a porous slab between described upper cover and described lower cover; The region that described lower cover and described porous slab surround is provided with a suction port and an air outlet; Be installed with multiple dividing plate between described upper cover and described porous slab, the region between described upper cover and described porous slab is divided into multiple noise reduction resonant cavity by described dividing plate; Described porous slab is provided with multiple through hole, and described through hole is distributed in noise reduction resonant cavity described in each.
Preferably, the volume of noise reduction resonant cavity described in each is all not identical.Like this, this steam outlet pipe assembly is made to have good erasure effect.
Preferably, described porous slab is curved plate, and described lower cover and described porous slab surround tubulose.Lower cover and porous slab define the steam outlet pipe passage in gas handling system.
Preferably, multiple depressed part is covered with on described.Like this, the intensity of upper cover self can be improved.
Preferably, between described upper cover and described porous slab, be between described lower cover and described porous slab, between described upper cover and described lower cover and be welded to connect.Like this, the requirement of steam outlet pipe to Sealing can be met, reduce the use of Sealing, the effect reduced costs can also be reached.
Positive progressive effect of the present utility model is: be provided with the noise reduction resonant cavity that multiple volume is different in steam outlet pipe assembly of the present utility model, because a noise reduction resonant cavity can reduce the noise near a frequency range, therefore, multiple resonant cavity can reduce the noise of the multiple frequency range of motor, has good erasure effect; Noise reduction resonant cavity is located between upper cover and lower cover, can reduce gas handling system and take space in cabin, solve the problem of limited space in cabin and the numerous space anxiety brought of part.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment.
Fig. 2 is the solid assembling schematic diagram of the utility model preferred embodiment.
Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
As depicted in figs. 1 and 2, a kind of engine aspirating system steam outlet pipe assembly, it comprises upper cover 1 and lower cover 2, is provided with porous slab 3 between upper cover 1 and lower cover 2; The region that lower cover 2 and porous slab 3 surround is provided with suction port 21 and air outlet 22; Be installed with multiple dividing plate 4 between upper cover 1 and porous slab 3, the region between upper cover 1 and porous slab 3 is divided into multiple noise reduction resonant cavity 5 by dividing plate 4; Porous slab 3 is provided with multiple through hole 31, and through hole 31 is distributed in each noise reduction resonant cavity 5.The volume of each noise reduction resonant cavity 5 is all not identical.Porous slab 3 is curved plate, and lower cover 2 and porous slab 3 surround tubulose.
Lower cover and porous slab define the steam outlet pipe passage in gas handling system.The noise reduction resonant cavity that multiple volume is different is formed between upper cover and porous slab.Because a noise reduction resonant cavity can reduce the noise near a frequency range, therefore, multiple resonant cavity can reduce the noise of the multiple frequency range of motor, has good erasure effect.Noise reduction resonant cavity is located between upper cover and lower cover, like this, can reduce gas handling system and take space in cabin, solve the problem of limited space in cabin and the numerous space anxiety brought of part.
For improving the intensity of upper cover self, upper cover 1 can be provided with multiple depressed part 11.
For meeting the requirement of steam outlet pipe to Sealing, reducing the use of Sealing, all can adopt between upper cover 1 and porous slab 3, between lower cover 2 and porous slab 3, between upper cover 1 and lower cover 2 and be welded to connect.Like this, cost can also be made to reduce.
In description of the present utility model, it will be appreciated that, term " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that this only illustrates, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these mode of executions, but these change and amendment all falls into protection domain of the present utility model.
