Description
(1) technical field
The utility model relates to a kind of automotive muffler, particularly relates to a kind of silencing apparatus with S type dividing plate.
(2) background technique
Automobile noise is mainly from automobile exhaust noise.If do not add silencing apparatus, under certain speed, noise can reach more than 100 decibels.Secondly be engine noise and tyre noise, engine noise, when automobile runs well, can reach more than 90 decibels, and tyre noise the speed of a motor vehicle be 90 kilometers/time when above, can reach 95 decibels of left and right.Therefore, in vent systems, add silencing apparatus, can make automobile exhaust reducing noise 20-30 decibel.Automotive muffler is the constituent elements that automobile is conventional, is conducive to reduce the noise pollution in vehicle traveling process, utilizes sound wave stack principle of interference to be made.The principle of automotive muffler be exactly its automobile exhaust pipe be to be formed by two different pipelines of length, these two pipelines first separately cross again.Due to two pipelines length difference equal the half of the wavelength of the sound wave that automobile sends, when two row sound waves are interfered when stack, cancel out each other and weaken the sound intensity, sound is reduced, thereby plays the effect of noise reduction.Thereby existing silencing apparatus utilizes expansion cavity to realize sound wave conventionally interferes reduction acoustic energy mutually, and the dividing plate in expansion cavity is mostly level and smooth iron plate, can not play the effect that reduces acoustic energy.Therefore, be necessary existing silencing apparatus to improve, level and smooth dividing plate can be become to S type dividing plate, by the structure of S type, play the reduction to acoustic energy.
(3) model utility content
In order to overcome the deficiency of existing automotive muffler, the utility model provides a kind of silencing apparatus with S type dividing plate.
The technical solution of the utility model is achieved in that
A kind of silencing apparatus with S type dividing plate of this programme, comprises suction tude and expansion cavity, and described suction tude comprises the first suction tude and the second suction tude; Described expansion cavity comprises the first expansion cavity and the second expansion cavity; In described the first suction tude, be provided with the suction port that supplied gas enters; The structure that described the first suction tude is endcapped; The middle part of described the first suction tude is provided with pore; Between the enterprising gas port of described the first suction tude and pore, be provided with through hole; Described through hole arranged outside has sound-absorbing wall; In described the first suction tude, between pore and one end of the first suction tude sealing, be provided with some air outlet holes; In described the first expansion cavity, be provided with the first dividing plate; In described the second expansion cavity, be provided with second partition; On described the first dividing plate and second partition, be provided with hole 1 and hole 2; On described hole 1, be provided with horizontal S type ripple; On described hole 2, be provided with longitudinal S type ripple; Described the first suction tude is through the hole 1 on the first dividing plate and second partition; Described the second suction tude is through the hole 2 on the first dividing plate and second partition.
Further, in described sound-absorbing wall, be provided with sound absorbing material.
Further, described the second suction tude is the open pipeline configuration in sealing one end, one end.
Further, in described the second suction tude, be provided with through hole.
Usefulness of the present utility model is: simple in structure, easy to use, and utilize S type dividing plate further to weaken the acoustic energy amplifying in chamber, effective to the noise absorption of vehicle exhaust.
