Description
Technical field
It the utility model is related to automobile exhaust system noise elimination technique field, more particularly to automobile exhaust muffler pipe.
Background technology
At present, automobile industry has been developing progressively as the important pillar industry in China, wherein, running car power master
Will by gas and oil mixed fuel, work by combustion produces in cylinder, should during caused burning waste gas pass through automobile
Gas extraction system be discharged into outside car.
In automotive exhaust system, because engine can produce huge sound in the high temperature and high pressure gas after discharge is burnt
Ring, cause a certain degree of noise pollution, therefore silencer is set to reduce automobile engine generally in automotive exhaust system
Exhaust noise, to improve Consumer's Experience.Usual discharge of automobile exhaust fumes passage is longer, therefore is set in automotive exhaust system
There are the secondary silencer and main muffler being connected.Wherein main muffler is the larger tubular structure of cross-sectional area, and is correspondingly arranged at
Automobile rear has the region of larger space;Secondary silencer is located at the front end of main muffler, is mainly used in solution main muffler and disappears
The hypodynamic problem of acoustic energy, i.e., the reduction and absorption of exhaust noise are first carried out by secondary silencer, then carried out by main muffler
Noise reduction operation etc..
In the prior art, the front and rear end plate of silencer uses the structure type of plane, soundproof effect unobvious.
The content of the invention
The purpose of this utility model is to further improve the soundproof effect of silencer, there is provided a kind of automobile exhaust pipe
Silencer.
For the attainment of one's purpose, technical scheme provided by the utility model is:
A kind of automobile exhaust muffler pipe that the utility model is related to, it is characterised in that:It include front end-plate, end plate,
Some dividing plates, cylinder and blast pipe, described dividing plate are provided with multiple first through hole uniformly laid, and blast pipe is provided with multiple
The sunk part of several directions inwardly, described front end-plate and rear end are arranged with second through hole, front end-plate and end plate
Plate is separately fixed at the rear and front end of cylinder, and baffle interval is arranged between front end-plate and end plate, cylinder, front end-plate, rear end
Plate and dividing plate form several cavitys, and described blast pipe sequentially passes through front end-plate, dividing plate and end plate, and with front end-plate, every
Plate and end plate are seamlessly connected.
The utility model sets several symmetrical, side on the basis of existing silencer on the plate body of front and rear end plate
To sunk part inwardly, the sunk part plays a part of increasing air-flow buffer, advantageously reduces noise.
Preferably, coaxial blast pipe is equipped with described front end-plate, end plate and dividing plate and passes through hole, blast pipe is successively
Hole is passed through through blast pipe.
Preferably, the distance between adjacent separator, dividing plate and adjacent headend plate, dividing plate and adjacent end plate differ.
Preferably, form fit of the shape of described front end-plate, end plate and dividing plate with cylinder, front end-plate, rear end
The outer ring of plate and dividing plate is equipped with flange.The setting of flange facilitates the installation and replacing of dividing plate, front and rear end plate.
Using technical scheme provided by the utility model, compared with prior art, have the advantages that:
The utility model sets several symmetrical compared with traditional automobile exhaust muffler pipe on front and rear end plate,
The sunk part of direction inwardly, sunk part play a part of increasing air-flow buffer, are advantageous to noise decrease, therefore, this practicality
The new automobile exhaust muffler pipe being related to has more preferable erasure effect.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model automobile exhaust muffler pipe;
Fig. 2 is front end plate structure schematic diagram;
Fig. 3 is rear end plate structure schematic diagram;
Fig. 4 is diaphragm structure schematic diagram.
Embodiment
To further appreciate that content of the present utility model, the utility model is described in detail in conjunction with the embodiments, it is real below
Apply example to be used to illustrate the utility model, but be not limited to the scope of the utility model.
With reference to shown in accompanying drawing 1, a kind of automobile exhaust muffler pipe that the utility model is related to includes front end-plate 1, end plate
2nd, two dividing plates 3, cylinder 4 and blast pipe 5, the section of described cylinder 4 is ellipse.With reference to shown in accompanying drawing 2 and 3, front end-plate 1
Hole 11,21 is passed through with a blast pipe is opened up on end plate 2, blast pipe is recessed through each laying two around hole 11,21
The sunk part 12,22 of part 12,22, front end-plate and end plate is mutually corresponding.With reference to shown in accompanying drawing 4, set on described dividing plate 3
There are multiple first through hole 32 uniformly laid and a blast pipe corresponding with front and rear dividing plate to pass through hole 31.Blast pipe is provided with more
Individual second through hole 51.For convenience of installation, the outer ring of described front end-plate 1 and end plate 2 is equipped with flange 13,23.
With reference to shown in accompanying drawing 1, described front end-plate 1 and end plate 2 are separately fixed at the rear and front end of cylinder 4, two pieces every
The arranged for interval of plate 3 is between front and rear end plate, wherein the distance between first piece of dividing plate and front end-plate are 132mm, two pieces of dividing plates 3
