Abstract
The utility model discloses a rotating structure of an auxiliary muffler cylinder and relates to an improved technology of a muffler for an automobile. The rotating structure of the auxiliary muffler cylinder comprises an auxiliary muffler (4) and also comprises an elbow pipe (1); the elbow pipe (1) is of a 90-degree arc-shaped elbow pipe structure and is connected with an air inlet of the auxiliary muffler (4), and the end part of the elbow pipe (1) is connected with a connecting flange (2); and a sound adsorption layer (3) is arranged on the inner surface of the elbow pipe (1). The rotating structure of the auxiliary muffler cylinder solves the problem that the auxiliary muffler for the automobile is inconvenient to install as limited by the internal space of the automobile.
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 automobile is straight tube with secondary silencing apparatus connecting tube, and the restriction that is subject to interior space during installation is very inconvenient.
Summary of the invention
The utility model provides a kind of secondary silencer cylinder rotational structure, and the utility model has solved the very inconvenient problem of restriction that is subject to interior space when the secondary silencing apparatus of automobile is installed.
For addressing the above problem, the utility model adopts following technological scheme: secondary silencer cylinder rotational structure comprises secondary silencing apparatus 4; Also comprise bend pipe 1, described bend pipe 1 is 90 degree curve bend structures, bend pipe 1 auxiliary connection silencing apparatus 4 inlet holes, and the end of bend pipe 1 is connected with adpting flange 2, at bend pipe 1 internal surface sound-absorption layer 3 is arranged.
The utility model has good muffling effect, advantage easy for installation with secondary silencer cylinder 90-degree rotation angle.
Description of drawings
Fig. 1 is the utility model structural representation.
Symbol description among the figure: bend pipe 1, adpting flange 2, sound-absorption layer 3, secondary silencing apparatus 4.
Embodiment
The below is described in detail the utility model with best embodiment.
As shown in Figure 1, secondary silencer cylinder rotational structure comprises secondary silencing apparatus 4; Also comprise bend pipe 1, described bend pipe 1 is 90 degree curve bend structures, bend pipe 1 auxiliary connection silencing apparatus 4 inlet holes, and the end of bend pipe 1 is connected with adpting flange 2, at bend pipe 1 internal surface sound-absorption layer 3 is arranged.
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.
