Description
Technical field
The present invention espespecially establishes a dust cover in the decorative cover upper cover of transmission case relevant for a kind of decoration cover structure of motorcycle transmission case, with the structure in the cooling air importing transmission case of outside.
Background technique
Motorcycle is with the advantage of its flexibility, and by the glad means of transportation that is used as working, and wherein scooter motorcycle is owing to have the operation ease of continuous variable speed, and the outward appearance of novel moulding, and its occupancy is improved every year.
With regard to scooter motorcycle, see also shown in Fig. 1,2, its power unit is by engine 1 and 2 integrated compositions of transmission case, the inside of this transmission case 2 is provided with belt speed change mechanism 20, this belt speed change mechanism 20 sets firmly a drive plate 22 in the left side that the axle of bent axle 11 1 sides arranges slider disc 21, be provided with plural fan blade 221 in the outside of drive plate 22, this drive plate 22 will move the driven disc 23 that is passed to transmission case 2 the other ends via V-shape belt 222, and finally transfer to rear-wheel spindle 25 via gear train 24; The outside of transmission case 2 is provided with a transmission-case cover 26, covers in transmission case 2 outer sides, and this transmission-case cover 26 forms an air window 261 in nearly drive plate 22 places, and is provided with an exhaust port 262 in the rear end of transmission-case cover 26.
Be covered with decorative cover 3 on this transmission-case cover 26, this decorative cover 3 mainly is made of a front decorative cover 31 and a rear decorative cover 32, and the shape of the shape of this decorative cover 3 and transmission-case cover 26 is similar.The front end of decorative cover 31 is inboard before being somebody's turn to do, and is covered with air guide sleeve 4, and this air guide sleeve 4 can form an air guiding chamber 311, in addition, should before the rear end (towards tailstock direction) of decorative cover 31 extended an extension part 312, in the diversion division 321 of rear decorative cover 32, and can form an air guide hole 33 by these extension part 312 cover caps.
The centre of this air guide sleeve 4 is provided with exhaust outlet 41, this exhaust outlet 41 is provided with filter assemblies 43, this filter assemblies 43 is between air guide sleeve 4 and front decorative cover 31, by this can be with by the extraneous cooling air of air guide hole 33 through air guiding chamber 311, carry out filter action before entering transmission case 2, in order to do making transmission case 2 obtain clean cooling air.This exhaust outlet 41 is corresponding with the air window 261 on the transmission-case cover 26.In addition, one side of air guide sleeve 4 becomes the flow-guiding mouth 42 of diffusion type, the ora terminalis of this flow-guiding mouth 42 just is connected mutually with the front-end edge of the diversion division 321 of rear decorative cover 32, can form a ventilation flue by this, make the cooling air in the external world compulsory from air guide hole 33 in ventilation flue enters air guiding chamber 311.
The front end of rear decorative cover 32 is skewed extending, and forms diversion division 321, has a plurality of water conservancy diversion fins 3211 on these diversion division 321 outsides, and this diversion division 321 can be intercalated in extension part 312 1 sides of front decorative cover 31, is provided with a through hole 322 in the rear end of rear decorative cover 32.
Known to after engine 1 activation, band dynamic crankshaft 11 rotates, driven again drive plate 22 rotations of the belt speed change mechanism 20 in the transmission case 2 by bent axle 11, and then the fan blade 221 in drive plate 22 outsides is rotated, form one suction, by the air window 261 of this strand suction on transmission-case cover 26, come the air guiding chamber 311 of front decorative cover 31 is produced attraction force again.By this, can be with transmission case 2 needed cooling airs, by air guide hole 33 importings of decorative cover 3, and through ventilation flue and air guiding chamber 311, exhaust outlet 41 by air guide sleeve 4 is inhaled in the transmission case 2 again, and is discharged by exhaust port 262 and through hole 322, in order to do belt speed change mechanism 20 coolings that can make in the transmission case 2.
Existing transmission case 2 is by above-mentioned decorative cover 3, can reach the purpose that belt speed change mechanism 20 is cooled off, yet, because the cooling air in this transmission case 2 is sucked in the transmission case 2 by the air guide hole 33 of decorative cover 3, when motorcycle when advancing at a high speed, cooling air is with other through decorative cover 3 at a high speed, and then causes cooling air to be difficult for being inhaled in the transmission case 2 by air guide hole 33, therefore cause easily strap speed varying system 20 cooling effectivenesss in this transmission case 2 not enough, and affect the running of engine 1.
Because existing transmission case decorative cover has above-mentioned disappearance, be necessary to develop the transmission case decorative cover that can effectively cooling air be imported in the means of motorcycle gearbox.
Summary of the invention
Main purpose of the present invention, be to be to provide a kind of decoration cover structure of motorcycle transmission case, be provided with belt speed change mechanism in this transmission case, this transmission-case cover is provided with an air window, this decorative cover has a front decorative cover and a rear decorative cover, should be provided with the first wind inlet corresponding to air window place by front decorative cover, extended an extension part in the rear end of front decorative cover, this extension part cover cap and can form the second wind inlet on the diversion division of rear decorative cover, wherein, should be covered with a dust cover on front decorative cover the first wind inlet, and by this, can avoid the first wind inlet to suck too much dust, and can prevent that foreign matter is inhaled in the transmission case, and then reach the radiating efficiency of effective increase transmission case.
