Specific embodiment

The invention will be further described for Specification For Structure the drawings and specific embodiments below.

On a kind of ventilation device of the gear-box of motorcycle as shown in Figure 1 and Figure 2, including air filter 2 and gear-box 1 Blow vent 11, air filter be equipped with independently of air filter work chamber ventilation box 3, ventilation box 3 be equipped with 34 He of air inlet The blow vent 11 of gas outlet 35, gear-box is connected to the air inlet 34 through snorkel 6, is equipped between inlet, outlet 34,35 circuitous Tortuous labyrinth air flue is returned, prevent water and dust from entering snorkel and then enters gear-box；Realize the exhaust of oil in gear-box Be provided simultaneously with outstanding water proof and dust proof performance, can be prevented impact of the gas outlet by high pressure water even if when cleaning vehicle water into Enter gear-box.

Ventilation box 3 separately fabricated can be mounted in air filter 2, or be integrally formed with air filter 2, referring to Fig. 3 to Fig. 8, be The first embodiment of the invention, air filter 2 have first shell 21, second shell 22, and ventilation box 3 includes and the first shell Point of air filter 2 is dexterously utilized in the integrally formed box body I 31 of body 21 and the box body II 32 integrally formed with second shell 22 Mode structure completes the combination of ventilation box 3 while assembling air filter 2.

It is equipped with retaining wall 5 inside ventilation box 3 and forms multiple ventilation chambers 4, connects between each adjacent chamber via venthole 41 It is logical, it is dislocatedly distributed between venthole 41, the air inlet 34 and gas outlet 35 are separately positioned on two chambers being relatively distant from 4, So that airflow channel is flowed through venthole 41 to gas outlet 35 from air inlet 34 and form the full of twists and turns labyrinth air flue, realizes waterproof Dust-proof function.

It is folded with filter core bracket 23 between the first shell 21 and second shell 22 of air filter, and the retaining wall 5 in box 3 of ventilating The bracket retaining wall 51 being folded between ventilation box box body I, II can be extended by 23 one of filter core bracket and/or by ventilation box box body I 31, the box body retaining wall 52 that II 32 inner wall of box body extends will be separated to form multiple ventilation chambers 4 inside ventilation box 3.

Specific as shown in Figures 4 to 7, the bracket retaining wall 51 at box body retaining wall 52 towards middle part extends and is against bracket retaining wall 51 On, four ventilation chambers, respectively chamber A, chamber B, chamber are separated by bracket retaining wall 51, box body retaining wall 52 in ventilation box 3 Room C and chamber D, whereinIndicate the oil gas flow direction of A, B, D chamber,Indicate the oil gas of A, C, D chamber And machine oil flow direction, ventilation box 3 are located at the tail end of air filter 2 and are obliquely installed, and are convenient for arranging oil gas and machine oil when vehicle to run Rearward, at this point, chamber A and chamber B is located at the top of ventilation box 3, and cavity C and chamber D are located at lower part, and air inlet 34 is arranged On chamber A, when oil gas or oil gas enter chamber A from air inlet 34 along with machine oil, a part of oil gas is set from chamber A highest point Some ventholes enter chamber B, a part of oil gas and machine oil because of the tilt angle for box of ventilating, and are affected by gravity toward flowing down, pass through The venthole that chamber A lowest part is equipped with enters cavity C, and then chamber B is same as cavity C is made by the venthole that lowest part is equipped with Oil gas and machine oil are uniformly flowed in chamber D again and are discharged by venthole；And water flow or silt dust are wanted to enter gear-box in turn, Multiple high points, which need to be crossed, just can enter in snorkel, it is clear that be difficult to enter, to realize the functions of waterproof and dustproof of ventilation box； And gas outlet 35 is opened up towards vehicle interior side, is blocked wet rain environment in driving process by box body of ventilating and is descended the water to splash and different Object enters rainwater or muddy water in ventilation box 2 from easily passing through gas outlet 35.

As shown in figure 8, in order to simplify the manufacture of ventilation box 3, the peripheral wall fitting sle of box body I 31 is mounted in the box body II 32 weeks Outside wall, box body I 31 wherein there are gaps between one section of peripheral wall and box body II 32 as gas outlet 35, without designing other structures As gas outlet 35.

Ventilating, also there are many set-up modes to be arranged in air filter for box 3, such as: the side that air filter 2 leans on wheel is arranged in, leads to It crosses 2 ontology of air filter and vehicle body blocks the rainwater of splashing or muddy water, to realize better waterproof effect.

In addition, snorkel 6 in order to facilitate the installation of, be equipped at blow vent 11 and air inlet 34 be connected to it is internal hollow vertical Column, blow vent 11 and air inlet 34 are respectively the inner hole of hollow column, and snorkel 6 can be directly sleeved on hollow column.

Demonstrated in Figure 9 is second of embodiment of the invention, and the retaining wall 5 ventilated in box 3 is only prolonged by filter core bracket 23 The bracket retaining wall 51 stretched forms, and can also form full of twists and turns labyrinth air flue, realize the function of water proof and dust proof.

Particular embodiments described above is only used to explain structure and realization principle of the invention, is not limited to this Invention, it is all to should all be included in the protection scope of the present invention with the replacement of the invention being equal or improvement.
