Abstract
The utility model discloses a kind of forced air-cooled exhaust silencer, comprise the only circle for air inlet, outlet pipe and silencing apparatus, outlet pipe one end is connected with only enclosing, and the other end is connected with silencing apparatus; It is characterized in that, described outlet pipe is curved shape and bending part forms windward side forward, described outlet pipe is sheathed is outward fixed with a wind scooper, wind scooper is positioned at position, windward side and offers intake grill, between wind scooper and outlet pipe, interval arranges and forms distinguished and admirable interlayer, leaves the clearance space supplying air-out between wind scooper two ends and only circle and silencing apparatus.The utility model can improve outlet pipe cooling effect, improves Motor-cyclist's leg protection effect, has structure simple simultaneously, implements the advantages such as convenient, with low cost.
Description
Technical field
The utility model relates to motorcycle engine field; Particularly relate to a kind of exhaust silencer for motorcycle engine.
Background technique
The exhaust silencer of motorcycle engine is generally made up of outlet pipe and silencing apparatus two-part.The Main Function of exhaust silencer is the waste gas produced after discharging engine combustion, reduces exhaust sound and exhaust gas temperature.Because outlet pipe is directly connected with engine exhaust port, exhaust gas temperature in it is up to 600-900 degree, too high temperature can cause the enamelled coating of outlet pipe to come off, and then cause outlet pipe corrosion, affect outlet pipe outward appearance and function, and the too high temperature of outlet pipe can cause the accident of driver and passenger to be scalded.
For the problems referred to above, present common way relies on the head-on wind produced in motorcycle driving process to cool exhaust silencer, install backplate additional at the position easily contacted with people simultaneously, prevent from scalding, but cannot solve the problem so at all, once exhaust silencer outer surface enamelled coating has influence on car load outward appearance and function after coming off, can only change, maintenance cost is high.
Model utility content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how to provide a kind of structure simple, improve outlet pipe cooling effect, improve the forced air-cooled exhaust silencer to Motor-cyclist's leg protection effect simultaneously.
In order to solve the problems of the technologies described above, the utility model have employed following technological scheme:
A kind of forced air-cooled exhaust silencer, comprise the only circle for air inlet, outlet pipe and silencing apparatus, outlet pipe one end is connected with only enclosing, and the other end is connected with silencing apparatus; It is characterized in that, described outlet pipe is curved shape and bending part forms windward side forward, described outlet pipe is sheathed is outward fixed with a wind scooper, wind scooper is positioned at position, windward side and offers intake grill, between wind scooper and outlet pipe, interval arranges and forms distinguished and admirable interlayer, leaves the clearance space supplying air-out between wind scooper two ends and only circle and silencing apparatus.
After motorcycle being installed the utility model structure, the head-on wind produced in motorcycle driving process is forced to import in the space of wind scooper and outlet pipe formation, pressure cooling is carried out to outlet pipe and silencing apparatus, the surface temperature of outlet pipe and silencing apparatus can be effectively reduced like this, prevent the enamelled coating of outlet pipe from coming off, outlet pipe corrosion, the accident of driver and passenger is scalded, improve the reliability of exhaust silencer, reduce maintenance cost.
As optimization, described wind scooper is docked by the wind deflector of two cross section semicirculars in shape and is connected to form.Convenient like this processing and installation.
Further, on described outlet pipe outer surface, interval is fixed with several round nut to being oppositely arranged along circular diameter direction, cross section, and on round nut, screw-thread fit is provided with a screw, and the side compressing of two wind deflectors is fixed on round nut by screw.This spline structure is simple but fixing reliable, and convenient installation is fixing.
Again further, screw is positioned at wind deflector both sides and is respectively arranged with a packing ring for compressing.So more ensure the leakproofness of fixing reliable and stability and combination, prevent from leaking out.
Further, described packing ring is woven by wire and forms.Such packing ring can also play vibration damping and heat-blocking action further, avoids heat to be delivered on wind scooper.
In sum, the utility model can improve outlet pipe cooling effect, improves Motor-cyclist's leg protection effect, has structure simple simultaneously, implements the advantages such as convenient, with low cost.

Fig. 2 is the A-A view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
During concrete enforcement:
As shown in Figure 1-2, a kind of forced air-cooled exhaust silencer, comprises the only circle 1 for air inlet, outlet pipe 2 and silencing apparatus 4, outlet pipe 2 one end and stop circle 1 and be connected, and the other end is connected with silencing apparatus 4; Described outlet pipe 2 is for curved shape and bending part forms forward windward side, described outlet pipe 2 is sheathed is outward fixed with a wind scooper 3, wind scooper 3 is positioned at position, windward side and offers several intake grill 3c, between wind scooper 3 and outlet pipe 2, interval arranges and forms distinguished and admirable interlayer, leaves the clearance space supplying air-out between wind scooper 3 two ends and only circle 1 and silencing apparatus 4.
Wherein, described wind scooper 3 is docked by wind deflector 3a, 3b of two cross section semicirculars in shape and is connected to form.Convenient like this processing and installation.
Wherein, on described outlet pipe 2 outer surface, interval is fixed with several round nut 5 to being oppositely arranged along circular diameter direction, cross section, and on round nut 5, screw-thread fit is provided with a screw 7, and the side compressing of two wind deflectors 3a, 3b is fixed on round nut 5 by screw 7.This spline structure is simple but fixing reliable, and convenient installation is fixing.
Wherein, screw 7 is positioned at wind deflector both sides and is respectively arranged with a packing ring 6 for compressing.So more ensure the leakproofness of fixing reliable and stability and combination, prevent from leaking out.Described packing ring 6 is woven by wire and forms.Such packing ring 6 can also play vibration damping and heat-blocking action further, avoids heat to be delivered on wind scooper.
After motorcycle being installed the utility model structure, when motorcycle is exercised, the waste gas after burning enters outlet pipe 2 from stopping circle 1, then enters silencing apparatus 4, discharges after noise elimination.The head-on wind produced in motorcycle driving process is forced to import in the space that formed between wind scooper and outlet pipe from intake grill 3c, flow in the direction of the arrow, pressure cooling is carried out to outlet pipe and silencing apparatus, the surface temperature of outlet pipe and silencing apparatus can be effectively reduced like this, prevent the enamelled coating of outlet pipe from coming off, outlet pipe corrosion, the accident of driver and passenger is scalded, improve the reliability of exhaust silencer, reduce maintenance cost.
