Abstract
The invention discloses a kind of motorcycle exhaust blast pipe, the metal outer pipe set including ceramic inner pipe and ceramic inner pipe outer ring, sandwich establishment between ceramic inner pipe and metal outer pipe, the inwall of the ceramic inner pipe is provided with some axial guiding gutters, it is provided with some resilient support balls in the interlayer, filling-foam material in interlayer.Blast pipe provided by the present invention, it is ceramic inner pipe high temperature resistant, resistant to chemical etching, the service life of blast pipe can be improved；Filling-foam material in interlayer, using the heat insulation function of expanded material, effective trap heat is conducted to metal shell, metal shell temperature is unlikely to Tai Gao and is damaged to human body；The guiding gutter set in ceramic inner walls, the gases at high pressure in blast pipe are made to shunt discharge, in addition, resilient support ball and expanded material in interlayer suffer oppression vibration when ceramic inner pipe vibrates, so as to absorb the vibrational energy of ceramic inner pipe, weaken the vibration of ceramic inner pipe, effectively reduce the noise of blast pipe.
Description
Technical field
The present invention relates to blast pipe technical field, more particularly to a kind of motorcycle exhaust blast pipe.
Background technology
Currently marketed motorcycle exhaust blast pipe is generally discharge duct made of aluminum alloy or steel alloy, knot
Structure is relatively simple, and cost of manufacture is also more cheap, but there are problems that using upper because the gas in blast pipe be from
The gases at high pressure discharged in engine, temperature is high, and has chemical corrosivity, causes the blast pipe of existing metal material to consume
It hurry up, service life is short, and blast pipe skin temperature is also high, easily scalds other people；High pressure draught passes through blast pipe, and noise is very big.
The content of the invention
The present invention is above-mentioned in order to overcome the shortcomings of, there is provided a kind of futuramic motorcycle exhaust blast pipe, including pottery
The metal outer pipe that porcelain inner tube and ceramic inner pipe outer ring are set, sandwich establishment between ceramic inner pipe and metal outer pipe, in the ceramics
The inwall of pipe is provided with some axial guiding gutters, and some guiding gutters are uniformly distributed around the axial line of ceramic inner pipe, the folder
Some resilient support balls are provided with layer, the resilient support ball is tangent with the outer wall of ceramic inner pipe and is fixedly connected at point of contact,
Resilient support ball is tangent with the inwall of metal outer pipe and is fixedly connected at point of contact, filling-foam material in interlayer, expanded material
Interlayer is filled up, is brought into close contact with the outer wall of ceramic inner pipe, when ceramic inner pipe vibrates, expanded material is oppressed and vibrated, and absorbs
The vibrational energy of ceramic inner pipe, weaken the vibration of ceramic inner pipe.
Preferably, some resilient support balls are uniformly distributed setting around ceramic inner pipe axial line.
Preferably, the resilient support ball includes small ball and big elastic ball, it is small positioned at big elastic ball inside and
With big elastic ball inscribe, small ball is fixedly connected with big elastic ball at point of contact.
Preferably, big elastic ball and small ball are tangent at resilient support ball and the tie point of metal outer pipe.
The beneficial effects of the invention are as follows：Blast pipe provided by the present invention, it is ceramic inner pipe high temperature resistant, resistant to chemical etching, can
Improve the service life of blast pipe；Filling-foam material in interlayer, using the heat insulation function of expanded material, effective trap heat to
Metal shell conducts, and metal shell temperature is unlikely to Tai Gao and is damaged to human body；The guiding gutter set in ceramic inner walls,
The gases at high pressure in blast pipe are made to shunt discharge, in addition, the resilient support ball and expanded material in interlayer vibrate in ceramic inner pipe
When suffer oppression vibration, so as to absorb the vibrational energy of ceramic inner pipe, weaken the vibration of ceramic inner pipe, effectively reduce making an uproar for blast pipe
Sound.
Brief description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is the forward structure schematic diagram of the present invention；
Fig. 2 is the cross-sectional structure schematic diagram of the present invention.
Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
As shown in Figure 1 and Figure 2, the present invention is outside a kind of motorcycle exhaust blast pipe, including ceramic inner pipe 1 and ceramic inner pipe 1
The metal outer pipe 2 set, sandwich establishment 3 between ceramic inner pipe 1 and metal outer pipe 2 are enclosed, the inwall of the ceramic inner pipe 1 is provided with
The guiding gutter 4 of guiding gutter 4,12 of 12 axial directions is uniformly distributed around the axial line of ceramic inner pipe 1, is set in the interlayer 3
There are multiple resilient support balls 5, the resilient support ball 5 is tangent with the outer wall of ceramic inner pipe 1 and is fixedly connected at point of contact, elasticity
Support ball 5 is tangent with the inwall of metal outer pipe 2 and is fixedly connected at point of contact, filling-foam material 6 in interlayer 3.
Multiple resilient support balls 5 are uniformly distributed setting around the axial line of ceramic inner pipe 1.
The resilient support ball 5 includes small ball 7 and big elastic ball 8, small ball 7 inside big elastic ball 8 and
With the big inscribe of elastic ball 8, small ball 7 is fixedly connected with big elastic ball 8 at point of contact.
Big elastic ball 8 and small ball 7 are tangent at tie point of the resilient support ball 5 with metal outer pipe 2.
Blast pipe provided by the present invention, ceramic inner pipe high temperature resistant, resistant to chemical etching, can improve blast pipe uses the longevity
Life；Filling-foam material in interlayer, using the heat insulation function of expanded material, effective trap heat is conducted to metal shell, makes gold
Category skin temperature is unlikely to Tai Gao and human body is damaged；The guiding gutter set in ceramic inner walls, make the high pressure in blast pipe
Gas distribution is discharged, the vibration in addition, the resilient support ball and expanded material in interlayer suffer oppression when ceramic inner pipe vibrates, so as to
The vibrational energy of ceramic inner pipe is absorbed, weakens the vibration of ceramic inner pipe, effectively reduces the noise of blast pipe.
Above-mentioned according to the present invention is enlightenment, by above-mentioned description, relevant staff completely can without departing from
In the range of this invention technological thought, various changes and amendments are carried out.The technical scope of this invention is not limited to
In the content on specification, it is necessary to determine its technical scope according to right.
