Description
Technical field
Patent of the present invention relates to a kind of Vehicle Turbocharged engine aspirating system, is particularly arranged on the automobile-used disappointing noise silencer in car gas handling system.
Background technique
Turbosupercharger accelerates accelerator releasing operating mode anxious, closed throttle, air is also constantly being pressed into by the turbocompressor run up, gas handling system pressure is caused to cross engine surge line, cause engine surge, unresolved engine surge imports Decompression valves, and pressurized gas pass through the narrow and small pipeline of passage, produce high frequency to lose heart noise, traditional solution increases porous braiding hush pipe in suction tude.
Above noise solution can be with the problem of serving in the middle of reality uses, and it comprises: one, porous braiding hush pipe cost is high, and porous braiding hush pipe is made up of sound-absorbing cotton thread, steel wire, nylon wire, waterproof coating; Two, porous braiding hush pipe complex process manufacturing efficiency is low, and it is shaping through annular weaving by noise reduction cotton thread, steel wire, nylon wire, and cut by use length, cutting back edge does anticreep process, and waterproof coating is made on surface; Three, porous braiding hush pipe two ends linkage structure is complicated; Four, by its structural limitations, porous braiding hush pipe can only be arranged on dirty side suction tude, needs time-based maintenance in using process; Five, porous braiding hush pipe can not be implemented for special-shaped pipeline structure.
Summary of the invention
For the problems referred to above, a kind of automobile-used disappointing noise silencer of Patent design of the present invention, this baffler replaces by using a large spout instead many apertures, diminished by nozzle diameter, by spout noise energy by low-frequency transfer to the insensitive frequency range of people's ear, realize baffler through structure optimization and air filter is integrated, save arrangement space, reduce costs.
For achieving the above object, patent of the present invention is by the following technical solutions:
A kind of automobile-used disappointing noise silencer, comprise baffler outer cover and hush pipe, it is characterized in that: described baffler outer cover is made up of air filter housing, surface of shell is provided with connecting tube, hush pipe opening end is connected rear with connecting tube and air filter shell is through, and the hush pipe the other end blocks, and has multiple aperture at hush pipe wall, described hole diameter is set as 1 ~ 3mm, and the centre distance between adjacent apertures is greater than hole diameter more than 6 times; On described hush pipe little hole number must ensure foraminate sectional area summation be greater than 1.5 times of hush pipe center hole main jet road sectional area.
Further, described connecting tube has annular boss in air filter enclosure interior, and hush pipe opening end is inserted in annular boss, and the hush pipe the other end is fixed by bolt and air filter housing.
Further, the thickness of pipe wall 2 ~ 3mm of described hush pipe, the hollow hole of the hole on wall respectively perpendicular to hush pipe is axial in 90 degree of distributions.
Further, the aperture symmetry arrangement on described hush pipe wall, avoids gas shock to produce vibration.
The present invention by integrated design by hush pipe and air filter integrated, save material drop into, shorten the process-cycle, reduce assembly process.Compare existing porous hush pipe, the present invention can reduce costs simultaneously improving production efficiency greatly.
When mounted, patent hush pipe of the present invention is integrated in air cleaner assy, can effectively solve space Layout Problem, reduces and connects sealing surface, improves product sealing reliability.
Accompanying drawing explanation
Fig. 1 is the structural representation of patent of the present invention;
Fig. 2 is the sectional view in A-A direction in Fig. 1 of the present invention;
Fig. 3 is partial enlarged drawing in Fig. 2 of the present invention.
Embodiment
As shown in Fig. 1 ~ 3, a kind of automobile-used disappointing noise silencer, comprises baffler outer cover 1 and hush pipe 2 forms, and described baffler outer cover 1 is made up of air filter housing, and be provided with connecting tube 3 at surface of shell, connecting tube 3 has annular boss 31 in air filter enclosure interior.Described hush pipe 2 wall thickness 2 ~ 3mm; The hush pipe 2 one end open the other end blocks, and hush pipe 2 opening end 21 is connected with connecting tube 3, and hush pipe opening end 21 is through by connecting tube 3 and air filter shell.Hush pipe 2 is fitted through opening end 21 and is inserted in annular boss 31, and the other end adopts bolt 5 to be fastened on air filter housing.
As shown in Figure 3, have multiple aperture 4 at hush pipe 2 wall, the hole 4 on wall is divided into four groups by design quantity, respectively perpendicular to hush pipe 2 centre hole axis in 90 degree of distributions.On described hush pipe, hole 4 diameter is 1 ~ 3mm, and the centre distance of adjacent apertures 4 is greater than 6 times of hole diameters, and all orifice cross sectional amass summation and are greater than hush pipe 2 center hole main jet road sectional area 1.5 times.If aperture 4 distributes too near on described hush pipe, air-flow also can be mixed into large spray column by forming little spray column after aperture 4, and produce radiated noise, the centre distance therefore between adjacent apertures must be greater than hole diameter more than 6 times.The less sound-damping qualities of described hush pipe wall opening diameter is larger, and Kong Yue little processing is more difficult, and therefore diameter is decided to be 1 ~ 3mm.Aperture 4 symmetry arrangement on described hush pipe 2 wall, avoids gas shock to produce vibration.
Patent of the present invention simplifies muffler structure by integrated design cleverly, by integrated to hush pipe and air filter, reduce material and drops into, shorten man-hour, reduce operation, compares porous braiding hush pipe cost and reduces by 70%, manufacturing efficiency increase by 40%.
The above, it is only the better embodiment of patent of the present invention, not to doing any pro forma restriction in standard of the present invention, every know-why according to patent of the present invention, to any simple modification made for any of the above embodiments, equivalent variations or modification, still belongs in the scope of art solutions of the present invention.
