Description
Technical field
The utility model relates to a kind of auto parts and components, a kind of automobile sound absorber assembly of specific design.
Background technique
Along with the raising of people's living standard and the development of automotive industry, automobile has become a kind of important traffic tool, automotive muffler is automobile constituent elements commonly used, utilize sound wave stack principle of interference to be made, its Main Function is: reduce the exhaust sound of motor, and high-temp waste gas can be discharged safely and effectively.Silencing apparatus should guarantee that as the part of exhaust duct its exhaust is unimpeded, resistance is little and sufficient intensity.Silencing apparatus will stand 500 ℃ ~ 700 ℃ high-temperature exhaust airs, guarantees not damage, do not lose soundproof effect in the distance travelled of automobile regulation.The invention provides a kind of easy to connectly, tightness is good, and exhaust is smooth and easy, and soundproof effect is good, constitutionally stable muffler assembly.
The model utility content
The model utility purpose: the purpose of this utility model is to provide a kind of easy to connect, and tightness is good, and exhaust is smooth and easy, and soundproof effect is good, constitutionally stable automobile sound absorber assembly.
Technological scheme: a kind of automobile sound absorber assembly described in the utility model, comprise premuffler assembly and rear muffler assembly, described premuffler assembly comprise ball impression flange, the front suction tude that disappears, front disappear cylindrical shell and before the steam outlet pipe that disappears; Disappear after described rear muffler assembly comprises suction tude, after disappear cylindrical shell and after the steam outlet pipe that disappears; Described ball impression flange is fixedly connected with the suction port of the suction tude that before disappears, the air outlet of the suction tude that disappears before described with described before the disappear suction port of cylindrical shell be fixedly connected with, disappear before described cylindrical shell the air outlet with shown in before the disappear suction port of steam outlet pipe be fixedly connected with, disappear before described steam outlet pipe the air outlet with described after the disappear suction port of suction tude be fixedly connected with, the air outlet of the suction tude that disappears after described with described after the disappear suction port of cylindrical shell be fixedly connected with, disappear after described cylindrical shell the air outlet with described after the disappear suction port of steam outlet pipe be fixedly connected with, the air outlet of the steam outlet pipe that disappears before described with described after disappear and be fixedly connected with the stage clip bolt by flange between the suction port of suction tude.
Further, be provided with hook on the suction tude that disappears before described, be provided with hanger on the steam outlet pipe that disappears before described.
The utility model compared with prior art, its beneficial effect is: the utility model is easy to connect, tightness is good, exhaust is smooth and easy, soundproof effect is good, structural stability reduces the exhaust impact noise of vehicle, can be with the outlet of air-flow guiding specified position under the chassis.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 be disappear before described in the utility model steam outlet pipe the air outlet with described after the schematic diagram that disappears and be connected between the suction port of suction tude.
Embodiment
The below is elaborated to technical solutions of the utility model, but protection domain of the present utility model is not limited to described embodiment.
As illustrated in fig. 1 and 2, a kind of automobile sound absorber assembly comprises premuffler assembly and rear muffler assembly, described premuffler assembly comprise ball impression flange 1, the front suction tude 2 that disappears, front disappear cylindrical shell 3 and before the steam outlet pipe 4 that disappears; Disappear after described rear muffler assembly comprises suction tude 5, after disappear cylindrical shell 6 and after the steam outlet pipe 7 that disappears; Described ball impression flange 1 is fixedly connected with the suction port of the suction tude 2 that before disappears, the air outlet of the suction tude that disappears before described 2 with described before the disappear suction port of cylindrical shell 3 be fixedly connected with, disappear before described cylindrical shell 3 the air outlet with shown in before the disappear suction port of steam outlet pipe 4 be fixedly connected with, disappear before described steam outlet pipe 4 the air outlet with described after the disappear suction port of suction tude 5 be fixedly connected with, the air outlet of the suction tude that disappears after described 5 with described after the disappear suction port of cylindrical shell 6 be fixedly connected with, disappear after described cylindrical shell 6 the air outlet with described after the disappear suction port of steam outlet pipe 7 be fixedly connected with, disappear before described steam outlet pipe 4 the air outlet with described after disappear and be fixedly connected with stage clip bolt 11 by flange 10 between the suction port of suction tude 5, be provided with hook 9 on the suction tude that disappears before described 2, be provided with hanger 8 on the steam outlet pipe 4 that disappears before described.
Working principle and working procedure: utilize resonance sound-absorbing, when sound wave incides the resonance accent, because the unexpected variation of acoustic impedance, a part of acoustic energy will be reflected back sound source.Simultaneously under the effect of sound wave, the air column in the aperture produces vibration, and frictional damping makes again a part of acoustic energy change heat energy into and dissipates during vibration, only has a small amount of acoustic energy to radiate, thereby has reached the purpose of eliminating the noise.
As mentioned above, although represented and explained the utility model with reference to specific preferred embodiment, it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model that does not break away from the claims definition, can make in the form and details various variations to it.
