Description

A kind of steam hose arrangement of gear box of motorcycle

Technical field

The utility model is related to motorcycle, the steam hose arrangement of especially a kind of gear box of motorcycle.

Background technology

The engine gearbox of motorcycle is communicated with cylinder, and piston can cause gear-box air pressure inside to become when operating Change, if gear-box is closing, piston motion will be influenced, or since air pressure inside variation leads to engine permeability, need To open up the hole communicated with air in gear-box, with air pressure in balanced engine babinet, if but the venthole directly and air Communicating can cause to enter dust or rainwater, need to do certain protection.

Therefore, the venthole of engine gearbox needs to be connected to steam hose, while to prevent muddy water logical by gear-box Gas hose enters gear-box, usually can the ventilation end opening of gear-box steam hose be fixed on sky above it upward On filter, and the ventilation end of gear-box steam hose is covered with cover member.But when vehicle crosses puddle, the ponding meeting of splashing It is poured in inside cover member by the discharge outlet of cover member bottom and is flowed out again, existed and have part water and fall into steam hose and enter The possibility of gear-box.

Invention content

For overcome the deficiencies in the prior art, the utility model provides a kind of steam hose arrangement knot of gear box of motorcycle Structure.

Technical solution adopted by the utility model to solve its technical problems is：

A kind of steam hose arrangement of gear box of motorcycle, including gear-box and air filter, the gear-box are equipped with The end blow vent of the ventilation pipe stretched out upward, the ventilation pipe is located in the air filter, and the ventilation pipe is at least If there are one bending, its latter end is made to form downward or tilt reflux section directed downwardly.

The ventilation pipe includes the steam hose picked out from gear-box and the through tube that air filter shell is integrally formed Chamber；The perforation tube chamber and the working cavities of air filter completely cut off, and it is obliquely installed and is formed with upper and lower nozzle；The ventilation is soft Pipe end is connected to the upper orifice of perforation tube chamber, and perforation tube chamber is made to constitute the reflux section.

It expands to form open guide face at lower nozzle, that is, blow vent of the perforation tube chamber.

The guide face tilts down extension from below the blow vent.

The upper orifice of the perforation tube chamber is the tubulose connection mouth of protrusion setting；The steam hose suit is fixed on described Outside tubulose connection mouth.

The air filter shell is equipped with recess, and the tubulose connection mouth protrusion is arranged in the recess.

The recess side wall is equipped with open opening.

The utility model has the beneficial effects that：By making ventilation pipe be bent at least provided with one, and formed in its latter end Downward or reflux section directed downwardly is tilted, i.e. the position of blow vent is less than the peak of ventilation pipe, and rainwater or mud are by cover member When bottom opening is splash, even if into blow vent, can also flow back discharge under the inhibition of reflux section, and can not pour in down a chimney entrance In engine gearbox, waterproof and dustproof is effectively realized.

Description of the drawings

The utility model is further illustrated with reference to the accompanying drawings and examples.

Fig. 1 is one embodiment of the utility model；

Fig. 2 is the preferred embodiment of the utility model；

Fig. 3 is the assembling schematic diagram of Fig. 2 embodiments；

Fig. 4 is partial enlarged view at the A of Fig. 3；

Fig. 5 is the section B-B figure of Fig. 3.

Specific implementation mode

One embodiment of the utility model referring to Fig.1.The steam hose arrangement of gear box of motorcycle includes gear Case 1 and air filter 2, gear-box 1 are equipped with the ventilation pipe 3 stretched out upward, and the end blow vent 31 of ventilation pipe 3 is located at the sky On filter 2, ventilation pipe 3 is bent at least provided with one, its latter end is made to form downward or tilt reflux section 32 directed downwardly.

Reflux section directed downwardly is formed downward or tilts by making ventilation pipe 3 be bent at least provided with one, and in its latter end 32, i.e. the position of blow vent 31 is less than the peak of ventilation pipe 3, when rainwater or mud are splash by cover member bottom, even if into Enter blow vent 31, can also flow back discharge under the inhibition of reflux section 32, and can not pour in down a chimney into engine gearbox 1, Effectively realize waterproof and dustproof.

It is the preferred embodiment of the utility model with reference to Fig. 2 to Fig. 5.Specifically, ventilation pipe 3 includes being connect from gear-box 1 The perforation tube chamber 5 that the steam hose 4 and 2 shell of air filter gone out is integrally formed；Penetrate through the working cavities of tube chamber 5 and air filter 2 Isolation, and it is obliquely installed and is formed with upper and lower nozzle；4 end of steam hose is connected to the upper orifice of perforation tube chamber 5, makes perforation Tube chamber 5 constitutes the reflux section 32.

By making 2 integrally formed perforation tube chamber 5 of air filter form reflux section 32, become first, steam hose 4 is easy bending Shape is difficult to ensure the position and stable structure of reflux section 32 in special circumstances, and integrally formed perforation tube chamber 5 is then fine Ground overcomes the destabilizing factor；Second is that steam hose 4 is accessed by 2 outside of air filter, blow vent 31 is then located at 2 inside of air filter And under the covering in cover member, the position of original blow vent 31 was not only met, but also convenient for the installation of steam hose 4, nothing It needs as carrying out assembly fastening in the small space below 3 inside of air filter i.e. cover member in the past.

In addition, expanding to form open guide face 51 at lower nozzle, that is, blow vent 31 of perforation tube chamber 5, convenient for the drippage that splashes Muddy water discharge at blow vent 31；And so that guide face 51 is tilted down from 31 lower section of blow vent from interior past other places and prolong It stretches, i.e., blow vent 31 is located at the top of guide face 51, opposite in a high position, has more structurally sound waterproof and dustproof effect.

The upper orifice for penetrating through tube chamber 5 is the tubulose connection mouth 52 of protrusion setting；Steam hose 4 is sleeved on tubulose connection mouth 52 Outside, and using pipe collar 6 it is fastened, firm and reliable connection.

Further, 2 shell of air filter is additionally provided with recess 21, and 41 protrusion of tubulose connection mouth is arranged in recess 2, Neng Gouyou Effect protection tubulose connection mouth 41, avoids collision and fractures；And further open opening, fastener tube can be equipped in the side wall of recess 21 Operation can be stretched into when binding round 6 by the open opening, it is more convenient.

Arrangement by the utility model to engine gearbox ventilation pipe 3 in air filter 2 realizes good anti- Water, dust-proof effect avoid the problem of previous blow vent 31 is easy sucking rainwater mud upward, simple in structure, easy to assembly.
