Description
Technical field
The utility model relates to a kind of automobile exhaust silencer, particularly a kind of automobile exhaust muffler.
Background technique
The level acoustic wave filter structure generally adopted a suction tude and a steam outlet pipe after the vent systems in the past, and this structure is unfavorable for the reduction of exhaust back pressure; Perhaps two of two suction tude steam outlet pipe independently, but this structure is comparatively complicated, and cost of production is higher, complex manufacturing.
Publication number is CN 101194089A, denomination of invention is that the patent application specification of Vehicular silencer discloses a kind of independently exhaust silencer of steam outlet pipe of a suction tude and two that has, this silencing apparatus effectively reduces exhaust back pressure, reduced the power loss of motor, but the structure of this silencing apparatus and production technology are also comparatively complicated.
The model utility content
The purpose of this utility model provides a kind of simple in structure, the exhaust silencer that can effectively reduce the silencing apparatus exhaust back pressure and have good noise reduction.
For solving the problems of the technologies described above, the utility model exhaust silencer is made of housing, right end cap, left end cap, suction tude, steam outlet pipe, first dividing plate, second partition, the 3rd dividing plate and diaphragm and interior pipe, described suction tude is passed housing and is extended through the diaphragm of silencing apparatus inside, fixedly connected with diaphragm, described diaphragm two ends are connected with the second partition vertical fixing with first dividing plate respectively; Described first dividing plate, second partition, the 3rd dividing plate be arranged in the housing and perpendicular to housing axially, fixedly connected with housing; Pipe passes first dividing plate, the 3rd dividing plate and extends in the cavity between the 3rd dividing plate and the left end cap in described; Described steam outlet pipe passes first dividing plate, second partition, the 3rd dividing plate, and two ends are extended and are opened on respectively on right end cap and the left end cap, are provided with sound attenuation hole on the tube wall of the steam outlet pipe between first dividing plate, the second partition.
Steam outlet pipe between second partition and right end cap is crooked to be provided with; Described diaphragm is provided with the vent in different apertures; Described suction tude, interior pipe are provided with sound attenuation hole; Described first dividing plate, second partition, the 3rd dividing plate are provided with the vent in different apertures; Be provided with glass fiber in the cavity between described first dividing plate and the 3rd dividing plate.
Adopt said structure, a steam outlet pipe connects the right end cap and the left end cap of silencing apparatus, and two air outlets are arranged, and makes the pressed gas outwards discharging fast in the silencing apparatus, effectively reduces the back pressure of vent systems, has reduced the power loss of motor.Steam outlet pipe between second partition and right end cap is crooked to be provided with, and has made things convenient for exhaust silencer to be lifted on hull back; Regulate perforate quantity and aperture on the diaphragm, the noise reduction frequency is moved; Gas enters silencing apparatus by suction tude, through entering the resonant cavity of both sides after the expansion, have the vent in different apertures on first dividing plate, second partition and the 3rd dividing plate, the supplied gas circulation, further reduced exhaust noise, by between first dividing plate and the 3rd dividing plate, in the cavity glass fiber being set, further reduced exhaust noise.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described further:
Fig. 1 is a structural representation of the present utility model;
In Fig. 1,1, suction tude; 2, first dividing plate; 3, the 3rd dividing plate; 4, housing; 5, interior pipe; 6, steam outlet pipe; 7, second partition; 8, right end cap; 9, diaphragm; 10, left end cap.
Embodiment
As shown in Figure 1, this exhaust silencer that is installed in automobile tail is made of housing 4, right end cap 8, left end cap 10, suction tude 1, steam outlet pipe 6, first dividing plate 2, second partition 7, the 3rd dividing plate 3 and diaphragm 9 and interior pipe 5, suction tude 1 is passed housing 4 and is extended through the diaphragm 9 of silencing apparatus inside, fixedly connected with diaphragm 9, diaphragm 9 two ends are connected with second partition 7 vertical fixing with first dividing plate 2 respectively; First dividing plate 2, second partition 7, the 3rd dividing plate 3 be arranged in the housing 4 and perpendicular to housing 4 axially, fixedly connected with housing 4; In pipe 5 pass first dividing plate 2, the 3rd dividing plate 3 and extend in the cavity between the 3rd dividing plate 3 and the left end cap 10; Steam outlet pipe 6 passes first dividing plate 2, second partition 7, the 3rd dividing plate 3, and two ends are extended and are opened on respectively on right end cap 8 and the left end cap 10, are provided with sound attenuation hole on the tube wall of the steam outlet pipe 6 between first dividing plate 2, the second partition 7.
Steam outlet pipe between second partition and right end cap is crooked to be provided with; Diaphragm 9 is provided with the vent in different apertures; Suction tude 1, interior pipe 5 are provided with sound attenuation hole; First dividing plate 2, second partition 7, the 3rd dividing plate 3 are provided with the vent in different apertures; Be provided with glass fiber in the cavity between the 3rd dividing plate 3 and the left end cap 10.
The gas that motor is discharged enters silencing apparatus by suction tude 1, through entering the resonant cavity of both sides after the expansion, by regulating perforate quantity and the aperture on the diaphragm 9, the noise reduction frequency is moved; Have the vent in different apertures on first dividing plate 2, second partition 7, the 3rd dividing plate 3, the supplied gas circulation; At last, gas enters sound attenuation hole on the steam outlet pipe 6 to the air outlet at two ends, discharges silencing apparatus.Because the air outlet area is the twice of suction port area, makes the back pressure of vent systems that tangible reduction be arranged, after the comparative trial checking, this structure reduces about 5KPa than the vent systems back pressure of having only an air outlet, has effectively reduced the power loss of motor.
