Description
Technical field
The utility model belongs to auto-parts technical field, and in particular to a kind of mobile muffler dividing plate.
Background technology
Mobile muffler is the important composition part of automobile, and the noise for advantageously reducing the generation of vehicle traveling process is dirty
Dye.Mobile muffler is broadly divided into resistive muffler, resistant noise-reducing device, impedance complex formula muffler according to operation principle.It is resistive
Muffler is exactly the sound absorption using sound-absorbing material, the noise propagated along passage is constantly gradually decayed by absorption.It is resistive
Muffler is suitable for eliminating the noise of middle and high frequency.Resistant noise-reducing device is that the pipeline section of the connection abrupt change of cross-section or side connect on pipeline
Resonant cavity, occurs the phenomenons such as reflection, interference in abrupt-change cross section using sound wave, so as to reach the purpose of noise elimination, is mainly used in arrowband
The control of noise and middle low noise.The impedance complex formula muffler used that resistive and two kinds of structure composites of resistance are got up is then knot
The two advantage has been closed, soundproof effect good in the range of basic, normal, high frequency has been realized.
At present, the fixation of the perforated pipe and dividing plate of muffler.Mainly by the way of gas welding or electric welding, in dividing plate and perforation
At the circular contact of pipe, the two is connected using several solder joints.But it is high because corrosion and engine exhaust frequency are higher
Warm pulse pneumatic, in addition road bumps easily cause coming off for perforated pipe and dividing plate, cause chamber not fix, influence muffler disappears
Audio is really.
Utility model content
The utility model provides a kind of mobile muffler dividing plate, has the advantages that simple in construction, good corrosion resistance.
To achieve the above object, the utility model provides following technical scheme：
A kind of mobile muffler dividing plate, including shell, connecting tube, dividing plate, the enclosure set fluted, it is described every
Plate two ends are fixed in the groove of shell, the connecting tube run through dividing plate, connecting tube the junction of dividing plate be in arcuation spill,
Dividing plate is divided into preceding dividing plate and rear bulkhead, and preceding dividing plate and the rear bulkhead middle setting, which has, be provided with first on acoustical cotton, preceding dividing plate
The second circular hole is provided with circular hole, rear bulkhead, the center of circle of first circular hole and the second circular hole is misaligned, the diameter of the first circular hole
Diameter than the second circular hole is big.
Further, the dividing plate material is titanium material.
Further, the acoustical cotton is fireproof acoustic cotton.
A kind of mobile muffler dividing plate, its advantage is：
1. dividing plate of the present utility model is titanium material, corrosion resistance is strong, extends the muffler life-span, meets automobile light weight
Change and require；
2. dividing plate of the present utility model is double-layer structure, front and rear dividing plate sets the misaligned circular hole in the center of circle but also can extended and makes an uproar not only
Residence time of the sound in dividing plate, prevent noise transmission；
3. the utility model communicating pipe is concave at dividing plate, being capable of stationary barrier within the specific limits, it is to avoid noise reduction
Device loses contact using rear bulkhead and connecting tube for a long time and causes chamber not fix, and influences the using effect of muffler.
Brief description of the drawings
Fig. 1 is a kind of structural representation of mobile muffler dividing plate of the utility model.
Fig. 2 is a kind of preceding diaphragm structure schematic diagram of mobile muffler dividing plate of the utility model.
Fig. 3 is a kind of rear bulkhead structural representation of mobile muffler dividing plate of the utility model.
Label in accompanying drawing：1 is shell, and 2 be connecting tube, and 3 be dividing plate, and 4 be acoustical cotton, and 5 be the first circular hole, and 6 be the second circle
Hole.
Embodiment
The utility model is further described with reference to specific embodiment：
As shown in FIG. 1 to 3, in a kind of mobile muffler dividing plate, including shell 1, connecting tube 2, dividing plate 3, the shell 1
Portion sets fluted, and the two ends of dividing plate 3 are fixed in the groove of shell 1, and the connecting tube 2 is the air inlet pipe of mobile muffler
Or escaping pipe, connecting tube 2 is through dividing plate 3, and connecting tube 2 is in the spill that the junction of dividing plate 3 is in arcuation, and dividing plate material is titanium
Material, 3 points of dividing plate is preceding dividing plate and rear bulkhead, and preceding dividing plate and the rear bulkhead middle setting has acoustical cotton 4, and the acoustical cotton 4 is
It is provided with fireproof acoustic cotton, preceding dividing plate on the first circular hole 5, rear bulkhead and is provided with the second circular hole 6, first circular hole 5 and
The center of circle of two circular holes 6 is misaligned, and the diameter of the first circular hole 5 is bigger than the diameter of the second circular hole 6.
The embodiment of the above, simply preferred embodiment of the present utility model, only to explain that this practicality is new
Type, not limits the utility model practical range, therefore all in construction of the present utility model, the equivalence changes done of feature and principle
With improve etc., all should be included in present utility model application the scope of the claims.
