Abstract
The utility model relates to the variable noise elimination air-strainer of a kind of integral type multi-frequency, and comprise filter box, dirty air duct and silencing apparatus, described filter box is connected with dirty air duct, forms a closed cavity, and described silencing apparatus is arranged in closed cavity.Described silencing apparatus is Changable type silencing apparatus.Compared with prior art, the utility model, by changing different silencing apparatus, reaches the noise eliminating different frequency, realizes sharing at different automobile types and different motor, has that development cost is low, advantages of simple structure and simple.
Description
Technical field
The utility model relates to a kind of air-strainer, especially relates to the variable noise elimination air-strainer of a kind of integral type multi-frequency.
Background technique
The air entering motor need filter through air-strainer, in order to reduce the noise of engine aspirating system, be respectively insert two Inserting Tubes at air cleaner assy air inlet/outlet in prior art, until the central position of upper-lower casing reaches noise reduction object, belong to reactive muffler.To be sound connect resonant cavity etc. by sudden change place of pipeline section or side to reactive muffler in propagation of sound process, causes the change of impedance and the reflection, the interference that produce acoustic energy, thus reduce by silencing apparatus to extraradial acoustic energy, to reach the silencing apparatus of noise elimination object.
At present, along with the proposition of automobile hardware and software platform concept, the vehicle car load border of same factory exploitation is roughly the same, the product versatility requirement which results in gas handling system improves greatly, but because engine displacement is different, the configuration of turbosupercharging gas is different, causes varying of the performance of gas handling system.Particularly the difference of gas handling system acoustical behavior causes gas handling system different, and the development cost of product also improves thereupon.
Model utility content
The purpose of this utility model be exactly provide to overcome defect that above-mentioned prior art exists a kind of applied widely, reduce costs, the variable noise elimination air-strainer of structure simple integral type multi-frequency.
The purpose of this utility model can be achieved through the following technical solutions:
The variable noise elimination air-strainer of a kind of integral type multi-frequency, comprise filter box, dirty air duct and silencing apparatus, described filter box is connected with dirty air duct, forms a closed cavity, and described silencing apparatus is arranged in closed cavity.
Described silencing apparatus is Changable type silencing apparatus.
Described silencing apparatus is provided with the Changable type acoustic element for the formation of resonant cavity.
Described Changable type acoustic element comprise in Helmholtz's baffler, quarter-wave long tube baffler and porous baffler one or more.
Described filter box is connected with dirty air duct is detachable.
Described filter box is connected by snap, bolt mode or welding manner with dirty air duct.
Compared with prior art, the utility model has the following advantages:
(1) the utility model integrates dirty air duct and filter box, and adopts removable silencing apparatus, reaches the object of the noise eliminating different frequency, is applicable to dissimilar motor;
(2) can share in the gas handling system of the utility model between different platform, reach the object of saving development cost;
(3) the utility model structure is simple, easy for installation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is exploded perspective view of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As Figure 1-Figure 2, the variable noise elimination air-strainer of a kind of integral type multi-frequency, comprises filter box 1, dirty air duct 3 and silencing apparatus 2, and filter box is connected with dirty air duct, and form a closed cavity, silencing apparatus is arranged in closed cavity.
Silencing apparatus 2 is Changable type silencing apparatus.Silencing apparatus 2 is provided with the Changable type acoustic element for the formation of resonant cavity, comprise in Helmholtz's baffler, quarter-wave long tube baffler and porous baffler one or more, Changable type acoustic element can form the resonant cavity of multiple noise elimination, reaches the object of noise elimination.
Filter box 1 adopts detachable Placement with dirty air duct 3, as snap, bolt mode, welding manner etc., facilitates the replacing of silencing apparatus 2.
Above-mentioned variable noise elimination air-strainer, under guarantee profile does not become situation, changes the acoustic characteristics of gas handling system by changing internal muffler, the gas handling system reached between various dissimilar motor, different platform shares, and saves development cost.
