Abstract
The utility model relates to muffler technology field, and to a muffler which includes an amortization shell and an amortization core mounted in the amortization shell, wherein the amortization core consists of a screw rod and a turbulence strip, the turbulence strip is opened with an air hole, the turbulence strip is overlapped and drilled through the screw rod, and the amortization core is demountably connected to the amortization shell through the screw rod, and, furthermore, a protective casing is overlapped on the amortization shell and opened with a heat radiation hole. In the muffler provided by the utility model, the amortization core is formed by a plurality of round turbulence strips overlapped on the screw rod and opened with the air hole, the discharged air is eliminated through the air holes on the plurality of turbulence strips in turn, which can effectively decrease the noise produced by gas exhaust and has significant anechoic effects. The utility model has small structure, simple manufacture, convenient disassembly, clean and maintenance, which can be used in exhaust pipe of motorcycle, and also can be used for exhaust pipe of internal combustion engines, such as vehicle, tractor, and internal combustion motor.
Description
Technical field
The utility model relates to the baffler technical field.
Background technique
Baffler is a kind of component that are used for reducing noise.The baffler of motorcycle is exactly common a kind of noise reduction part that is installed on the outlet pipe.Because of motorcycle in running, also send very big noise when in atmosphere, discharging a large amount of high-temp waste gas by outlet pipe, environment is made noise pollution.Baffler is installed on the outlet pipe of motorcycle engine is used for reducing the noise that produces in the motor exhaust process.
Existing motorcycle baffler is to connect on the smoke-ejecting pipe that extends to the motor cycle rear wheel position from head, comprises inner core and shell two-part.Inner core mainly is the impact force of buffer gas, and inner core is made up of gas expansion chamber and tailpipe that dividing plate, air pipe are divided into, and generally there is two-stage in gas expansion chamber, so that buffer gas pressure.In order to increase silencing function, on the silencer casing wall, be provided with glass silk floss, chain link fence usually.The muffler structure volume of present this structure is bigger, and erasure effect is undesirable, is still waiting further improvement.
In addition, since waste gas that motorcycle engine produced be entirely through with baffler that outlet pipe is connected after just discharge, the waste gas of burning can produce carbon deposit in baffler, and the noise reduction shell and the baffler of existing baffler, outlet pipe all is fixedly connected integral structure, the carbon deposit that the baffler user of integral structure is inconvenient to remove in the baffler can cause exhaust to stop up, not only cause loss economically, and the using character of motor also impacted, easily cause being short of power of motor, acceleration performance is poor, also may make the mixed gas overrich simultaneously and excessive fuel consumption causes engine overheat, the sound is unusual, influences the inherent working life of motor.
The model utility content
Technical problem to be solved in the utility model provides the baffler of a kind of small and exquisite, corrosion-resistant, good muffling effect simple in structure and dismounting cleaning.
The utility model is achieved through the following technical solutions:
Design a kind of baffler, comprise the noise reduction shell and be arranged on the interior noise reduction core of noise reduction shell, the noise reduction core is made up of fixing rod and spoiler, offers vent on the spoiler, spoiler is set on the fixing rod, and the noise reduction core removably is connected on the noise reduction shell by fixing rod.
Improvement as such scheme, fixing rod adopts screw rod, spoiler is the circular piece that the center is provided with fixed hole, noise reduction shell one end is connected with outlet pipe, the other end is an exhaust nozzle, be provided with the fixed plate of band nut in the noise reduction shell termination that is connected with outlet pipe, screw rod one end of noise reduction core is connected with the nut of fixed plate, and the screw rod the other end links together by nut and exhaust nozzle.
As the further improvement of such scheme, also sheathed protective housing on the noise reduction shell offers radiation hole on the protective housing.
The utility model has following remarkable result compared to existing technology:
1, baffler of the present utility model, the noise reduction core is made of the circular spoiler that has vent that multi-disc is set on the screw rod, simple structure, and the gas of discharging is got rid of step by step through the vent of multi-disc spoiler successively, can effectively reduce the noise of the generation of exhaust, erasure effect is remarkable.
2, the noise reduction core of this baffler is connected on the noise reduction shell by its screw rod is dismountable, makes things convenient for the user to remove the noise reduction core from the noise reduction shell and clears up carbon deposit on the noise reduction core, can improve the working life that erasure effect can improve motor again.
3, the configuration of this baffler has the protective housing of radiation hole, can reduce the temperature on the baffler body effectively, has avoided because of the high scald phenomenon that takes place of temperature on the baffler.
4, the baffler with spoiler noise reduction core provided by the utility model, structure is small and exquisite, makes simply, not only can use on the outlet pipe of motorcycle, also can be at other internal-combustion engines, as automobile, tractor uses on the outlet pipe of internal combustion engine generator etc.

Fig. 3 is the schematic cross-section of Fig. 1.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
Referring to Fig. 1～3, a kind of baffler includes noise reduction shell 1, and the noise reduction shell is a cylindrical body, and noise reduction shell one termination is an exhaust nozzle 5, and another termination and outlet pipe 4 weld together.Be provided with the fixed plate 11 of band nut in the noise reduction shell termination that is connected with outlet pipe, dismountable noise reduction core is installed in the noise reduction shell, the noise reduction core is made up of screw rod 3 and spoiler 2, spoiler is the circular piece that the center is provided with fixed hole, offer vent 21 on the spoiler, the multi-disc spoiler is installed on the screw rod by the fixed hole at its center.Screw rod one end of noise reduction core is connected with the nut of fixed plate, and the screw rod the other end is connected with exhaust nozzle.Exhaust nozzle is the cap shape, and it is provided with the through hole that passes for screw rod, and screw rod and exhaust nozzle are fixed by nut.This noise reduction core is connected on the noise reduction shell by bolt and nut, makes things convenient for the user to remove the noise reduction core from the noise reduction shell and clears up carbon deposit on the noise reduction core, can improve the working life that erasure effect can improve motor again.
The noise reduction core of this baffler its mainly the spoiler by the overlapping setting of multi-disc reduce noise that exhaust produces, in order to increase the effect that reduces noise the vent on the overlapping spoiler that is arranged on the screw rod is staggered.Spoiler of the present utility model adopts the circular metal plate that aperture is set, simple in structure and easy to process, the waste gas that enters baffler can effectively reduce the noise of the generation of exhaust step by step through could getting rid of by auxiliary agent behind the vent of multi-disc spoiler, and erasure effect is remarkable.
Baffler of the present utility model also also is arranged with protective housing 6 on the noise reduction shell, offer radiation hole 61 on the protective housing.Can effectively reduce the heat that produces on the baffler at the protective housing that has been nested with the band radiation hole on the baffler, avoid because of the high scald phenomenon that takes place of temperature on the baffler.
