【考案の詳細な説明】
この考案はクリーナチャンバを設けたオートバイの燃料
タンクに関する。DETAILED DESCRIPTION OF THE INVENTION This invention relates to a motorcycle fuel tank provided with a cleaner chamber.
オートハイはシート下部の車体中央部にエアクリーナを
装着するが、この車体中央部にはバッテリや電装部品も
装着され、このため場所が狭く、エアクリーナを十分大
きくすることができない。Auto-high cars have an air cleaner installed in the center of the car body below the seat, but the battery and electrical components are also installed in the center of the car body, so the space is small and the air cleaner cannot be made large enough.
エアクリーナは容積が大きいほど、間欠的に急激に行わ
れるエンジンの吸気を減衰できて、吸気騒音を少くでき
る。The larger the volume of the air cleaner, the more it can dampen the intermittent and sudden intake of air from the engine, thereby reducing intake noise.
しかし上述のように、エアクリーナの大きさが制限され
るので、吸気を十分消音できず、騒音が発生して不快で
ある。However, as mentioned above, since the size of the air cleaner is limited, the intake air cannot be sufficiently muffled, causing unpleasant noise.
この考案はかかる点に鑑み改善したもので、以下図面に
示す本考案の実施例について説明する。This invention has been improved in view of these points, and the embodiments of the invention shown in the drawings will be described below.
燃料タンク１は底板２が断面逆Ｕ字状に凹めてあって、
フレーム３を跨ぐように、フレーム３の前上部に装着さ
れる。The fuel tank 1 has a bottom plate 2 recessed into an inverted U-shape in cross section.
It is attached to the front upper part of the frame 3 so as to straddle the frame 3.
而して本考案は、燃料タンク１の底板２に空隙４を設け
、重ね板５を溶接等によって固着する。According to the present invention, a gap 4 is provided in the bottom plate 2 of the fuel tank 1, and a stacked plate 5 is fixed by welding or the like.
重ね板５には空気口６を穿設し、空隙４の後端をバイブ
７でエアクリーナ８の吸入口９に連結する。An air port 6 is bored in the stacked plate 5, and the rear end of the gap 4 is connected to an inlet 9 of an air cleaner 8 by a vibrator 7.
１０はエンジン、１１はキャブレタ、１２はフレームカ
バー １３はシートを示す。10 is an engine, 11 is a carburetor, 12 is a frame cover, and 13 is a seat.
作用について説明する。The effect will be explained.
燃料タンク１の底板２に重ね板５を重ねて、底板２と重
ね板との間に設けた空隙４を、エアクリーナ８の吸入口
９にパイプＩで連結したので、空隙４がエアクリーナ８
のエアチャンバ室になる。The stacked plate 5 is stacked on the bottom plate 2 of the fuel tank 1, and the gap 4 provided between the bottom plate 2 and the stacked plate is connected to the intake port 9 of the air cleaner 8 with a pipe I, so that the gap 4 is connected to the air cleaner 8.
It becomes an air chamber room.
このようにして、エアチャンバ室を空隙によって増量で
きるので、吸気の減衰を大きくすることができて、吸気
騒音の低減が計れる。In this way, the volume of the air chamber can be increased by the air gap, so that the attenuation of intake air can be increased, and intake noise can be reduced.
又、空隙４はその外側が燃料タンク１になっているので
、内部の燃料が緩衝体となって、騒音の放出を吸収し、
この面でも騒音の低減が計れる。In addition, since the outside of the gap 4 is the fuel tank 1, the fuel inside acts as a buffer and absorbs noise emissions.
Noise can be reduced in this aspect as well.
以上説明したように、この考案は、フレームを跨ぐよう
に底板を断面逆Ｕ字状に凹めた燃料タンクに於て、該底
板との間に空隙を設けて重ね板を重ね、重ね板に空気口
を設けると共に、空隙の後端ヲエアクリーナの吸入口に
連結したので、底板と重ね板の間の空隙がエアクリーナ
のエアチャンバになり、吸気の減衰を大きくすることが
できて、吸気騒音の低減が計れる。As explained above, this invention is based on a fuel tank in which the bottom plate is recessed into an inverted U-shaped cross section so as to straddle the frame. In addition to providing an air port, the rear end of the gap is connected to the intake port of the air cleaner, so the gap between the bottom plate and the stacked plate becomes the air chamber of the air cleaner, increasing the attenuation of intake air and reducing intake noise. It can be measured.
又、空隙の外側には燃料があって、騒音の緩衝体になる
ので、この面でも吸気騒音が低減する。Further, since there is fuel outside the gap and it acts as a noise buffer, intake noise is also reduced in this aspect.
更に、重ね板に設けた空気口は熱料タンク１の凹部内に
あって、露出していないので、雨水の侵入も防げる。Furthermore, since the air holes provided in the stacked plates are located within the recessed portion of the heating material tank 1 and are not exposed, intrusion of rainwater can also be prevented.
