Abstract
The utility model relates to the effective silencing apparatus of a kind of automobile exhaust, comprises suppressor case, and suppressor case is provided with suction tude and outlet pipe, and suppressor case comprises outer muffler plate and internal layer muffler plate, and suction tude connects automobile exhaust pipe; Stretch in suppressor case in suction tude and outlet pipe, suction tude is vertically connected on a side end face of suppressor case, outlet pipe is vertically connected on the opposite side end face of suppressor case, insulation board is provided with in suction tude and outlet pipe, suppressor case is provided with along its axial direction the noise elimination stick that lamination coating makes, and the two ends of noise elimination stick are connected on the inwall of both sides end face of suppressor case.Expand in air chamber between internal layer muffler plate and outer muffler plate, reduce pressure, sound insulation cellucotton simultaneously between internal layer muffler plate and outer muffler plate produces larger acoustic resistance to air-flow, then shunt, finally by noise elimination stick and insulation board, be discharged into soundproof effect in air good.
Description
Technical field
The utility model relates to technical field of automobile parts, particularly relates to the effective silencing apparatus of a kind of automobile exhaust.
Background technique
Common silencing apparatus is that iron sheet inner surface of pipeline uses glass wool to add the dissipative muffler of perforation entrant sound facing (preventing glass fibre from being taken away by air-flow) sound absorption process, and the principle of noise elimination make use of the acoustic resistance that sound-absorbing material produces air-flow.The geometrical shape that air-flow path pressed by dissipative muffler is different, can be divided into the forms such as straighttube-type, chip, labyrinth type, baffle formula, bending head type.In general, dissipative muffler has good medium-high frequency acoustic characteristics, poor to low frequency acoustic attenuation performance.In order to improve the acoustic attenuation performance of dissipative muffler, suitably can increase unit weight and the thickness of centrifugally glass-wool sound-absorbing material in silencing apparatus, and improving the punching rate of finish material.
Automobile exhaust pipe is generally provided with silencing apparatus, to reduce noise, promotes generator power and energy-conservation effect.At present, existing silencing apparatus is mostly in tubular structure, the silencing apparatus of the structure of this tubular due to the restriction of structure, so that establishes the quantity of silencing apparatus and the setting of volume or adjustment to be all limited by very large in it, thus its effect reducing noise is difficult to further raising.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide the effective silencing apparatus of a kind of automobile exhaust, soundproof effect is good.
The utility model is achieved through the following technical solutions:
The effective silencing apparatus of a kind of automobile exhaust, comprise suppressor case, described suppressor case is provided with suction tude and outlet pipe, and described suppressor case comprises outer muffler plate and internal layer muffler plate, and described suction tude connects automobile exhaust pipe; Stretch in suppressor case in suction tude and outlet pipe, described suction tude is vertically connected on a side end face of suppressor case, described outlet pipe is vertically connected on the opposite side end face of suppressor case, insulation board is provided with in suction tude and outlet pipe, described suppressor case is provided with along its axial direction the noise elimination stick that lamination coating makes, and the two ends of described noise elimination stick are connected on the inwall of both sides end face of suppressor case.
As optimal technical scheme of the present utility model, the suppressor case that described outer muffler plate and internal layer muffler plate are formed is tubular, is filled with sound insulation cellucotton in the cavity in outer muffler plate and internal layer muffler plate.
As optimal technical scheme of the present utility model, the interlaced arrangement of described insulation board, its cross section is in " V " type.
As optimal technical scheme of the present utility model, the thickness of described noise elimination stick is 6-12mm.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, expand in air chamber between internal layer muffler plate and outer muffler plate, reduce pressure, sound insulation cellucotton simultaneously between internal layer muffler plate and outer muffler plate produces larger acoustic resistance to air-flow, then shunt, finally by noise elimination stick and insulation board, be discharged into soundproof effect in air good.
