Abstract
The utility model discloses a gas inlet pipe structure for a main muffler and relates to automobile muffler improvement technologies. The gas inlet pipe structure comprises the main muffler (4), wherein a gas inlet pipe (1) is mounted at the front end of the main muffler (4); and a connecting flange (2) is mounted at the front end of the gas inlet pipe (1), a silencing layer (3) is fixed on the internal surface of the gas inlet pipe (1) in a sticking manner, and the internal surface of the silencing layer (3) is of a wavy structure. According to the gas inlet pipe structure for the main muffler, the problems of good medium-high frequency silencing effect and poor low-frequency silencing effect of an automobile muffler are solved.
Description
Technical field
The utility model relates to the improvement technology of automotive muffler.
Background technique
Automotive muffler is automobile constituent elements commonly used, is conducive to reduce the noise pollution in the vehicle traveling process, and it utilizes sound wave stack principle of interference to be made.The dissipative muffler that automobile is commonly used mainly is that to utilize sound-absorbing porous material to fall low noise.Sound-absorbing material is fixed on the inwall of air-flow path or according to certain way and in pipeline, arranges, just consisted of dissipative muffler.When sound wave entered dissipative muffler, a part of acoustic energy rubbed in the hole of porous material and changes into thermal energy consumption and dissipates, and the sound wave by silencing apparatus is weakened.Dissipative muffler just looks like the pure resistor element circuit on the electricity, and sound-absorbing material is similar to resistance.Therefore, people just call dissipative muffler to this silencing apparatus.
Existing silencer for automobile is good, relatively poor to the low frequency soundproof effect to the medium-high frequency soundproof effect.
Summary of the invention
The utility model provides a kind of main muffler air feeder structure, and that the utility model has solved that automotive muffler exists is good to the medium-high frequency soundproof effect, to the relatively poor problem of low frequency soundproof effect.
For addressing the above problem, the utility model adopts following technological scheme: the main muffler air feeder structure, comprise main baffler 4, and main baffler 4 front ends are equipped with suction tude 1; Suction tude 1 front end is equipped with adpting flange 2, and suction tude 1 internal surface cementation has noise reduction layer 3, and the internal surface of noise reduction layer 3 is wavy shaped configuration.
Advantage of the present utility model: good muffling effect, easy for installation.
Description of drawings
Fig. 1 is the utility model structural representation.
Symbol description among the figure: suction tude 1, adpting flange 2, noise reduction layer 3, main baffler 4.
Embodiment
The below is described in detail the utility model with best embodiment.
As shown in Figure 1, the main muffler air feeder structure comprises main baffler 4, and main baffler 4 front ends are equipped with suction tude 1; Suction tude 1 front end is equipped with adpting flange 2, and suction tude 1 internal surface cementation has noise reduction layer 3, and the internal surface of noise reduction layer 3 is wavy shaped configuration.
Described noise reduction layer is soft roll structure, and the noise reduction layer is that flannelette or cotton parcel sponge material are made.
It should be noted that at last: obviously, above-described embodiment only is for the utility model example clearly is described, and is not the restriction to mode of execution.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And the apparent variation of being amplified out thus or change still are among the protection domain of the present utility model.
Claims (1)
1. the main muffler air feeder structure comprises main baffler (4), and main baffler (4) front end is equipped with suction tude (1); It is characterized in that suction tude (1) front end is equipped with adpting flange (2), suction tude (1) internal surface cementation has noise reduction layer (3), and the internal surface of noise reduction layer (3) is wavy shaped configuration.
