Abstract
The invention provides a combined resonator capable of removing noises at a plurality of frequencies at the same time. According to the combined resonator, an air duct is arranged in a large cavity. Silencing holes are formed in the air duct. A throat pipe is arranged on the air duct and a small cavity is connected with the tail end of the throat pipe. Both the throat pipe and the small cavity are arranged in the large cavity. A small resonator body is fixed to the large cavity and the large cavity and the small cavity correspond to noises at the two frequencies respectively, wherein the noises at the two frequencies need to be removed. The combined resonator has the advantages of saving arrangement space, simplifying the installation process of the resonator and reducing installation cost.
Description
Technical field
The present invention relates to a kind of combined type silencer element, particularly relate to a kind of combined resonator that is applicable to passenger car gas handling system.
Background technique
The major function of automotive engine air intake system is for motor provides clean ozone, and reduces the induction noise that is transmitted to external environment condition from engine interior.For the induction noise of low and medium frequency, major part can be eliminated by air-strainer, but the Middle and low frequency noise of indivedual frequencies need to be eliminated with resonator, as shown in Figure 1.During due to engine operation, often under different rotating speeds, produce different frequency and surpass the noise that designs noise targets, for meeting design requirement, these local slight elevated noise all need to use different volume resonator to go correspondingly to eliminate, so just cause a plurality of resonators difficult arrangement in compact engine compartment even cannot arrange, and fixing complexity is installed, and cost is higher.
Embodiment
Technical problem to be solved by this invention is to provide a kind of combined resonator that can simultaneously eliminate a plurality of frequency noises.
The technological scheme that technical solution problem of the present invention adopts is: combined resonator, breather line is arranged in large cavity, on described breather line, be provided with sound attenuation hole, on described breather line, be provided with trunnion, and be connected with little cavity at the tail end of described trunnion, and described trunnion and little cavity are all arranged in large cavity.
Further, in the situation that the aperture of described sound attenuation hole is identical, the quantity of sound attenuation hole is more, and the frequency of noise elimination of the large cavity of resonator is larger, and sound deadening capacity is also more simultaneously.
Further, in the situation that the quantity of described sound attenuation hole is identical, the aperture of sound attenuation hole is larger, and the frequency of noise elimination of the large cavity of resonator is larger, and sound deadening capacity is also more simultaneously.
The invention has the beneficial effects as follows: the present invention's employing is fixed little resonator and combined in large cavity, large cavity and loculus body be the noise to 2 frequencies in requisition for eliminating respectively.Combined resonator of the present invention has not only been saved arrangement space, has also simplified the installation of resonator, has reduced installation cost.
Embodiment
Because the volume that can arrange for noise elimination in existing engine compartment be limited, therefore, the present invention adopts combined resonator, as shown in Figure 2, breather line 2 is arranged in large cavity 1, described breather line 2 is pressed in large cavity 1 by force by the telescopic characteristic of ripple, and then ripple resilience is seated; On breather line 2, be provided with sound attenuation hole 3, to meet the noise elimination needs of 1 corresponding noise frequency of large cavity; 1 trunnion 4 is set in addition on breather line 2 again, and connect 1 loculus body 5 at the tail end of trunnion 4, to meet the noise elimination needs of the corresponding noise of another 1 frequency, and above-mentioned trunnion 4 and loculus body 5 are all arranged in large cavity 1, the noise elimination so both having met in finite volume is arranged, can be eliminated the again resonator of 2 frequency noises, as shown in Figure 3, is and has eliminated the frequency noise of general 200HZ with the difference of Fig. 1.
Because the noise elimination effect performance of resonator is only relevant with length with the cavity volume of resonator and the internal diameter of trunnion, have nothing to do with shape, the present invention's perforate on breather line 2 can play similar trunnion.Large cavity 1 of the present invention communicates with breather line 2 by sound attenuation hole 3, and loculus body 5 communicates with breather line 2 by trunnion 4.
What rely on the installation of vehicle body in the present invention is mounting bracket and the immovable point of large resonator, and little resonator is arranged on the inside of large resonator.
The setting position of above-mentioned sound attenuation hole 3, quantity and size can arrange as required.The inventor finds by research, and the frequency of noise elimination of the large cavity 1 of resonator of the present invention is relevant with aperture and the quantity of sound attenuation hole 3, and irrelevant with setting position, as shown in Figure 4.Wherein: A curve represents that the quantity of sound attenuation hole 3 is the sound deadening capacity curve that 60, the aperture of sound attenuation hole 3 are 4mm; B curve represents that the quantity of sound attenuation hole 3 is the sound deadening capacity curve that 40, the aperture of sound attenuation hole 3 are 4mm; C curve represents that the quantity of sound attenuation hole 3 is the sound deadening capacity curve that 20, the aperture of sound attenuation hole 3 are 5mm; D curve represents that the quantity of sound attenuation hole 3 is the sound deadening capacity curve that 16, the aperture of sound attenuation hole 3 are 5mm; E curve represents that the quantity of sound attenuation hole 3 is the sound deadening capacity curve that 20, the aperture of sound attenuation hole 3 are 4mm.As can be seen from the figure: within the specific limits, in the situation that the aperture of sound attenuation hole 3 is identical, the quantity of sound attenuation hole 3 is more, and the frequency of noise elimination of the large cavity 1 of resonator is larger, sound deadening capacity is also more simultaneously; In the situation that the quantity of sound attenuation hole 3 is identical, the aperture of sound attenuation hole 3 is larger, and the frequency of noise elimination of the large cavity 1 of resonator is larger, and sound deadening capacity is also more simultaneously.
