【考案の詳細な説明】
この考案は、モトクロス型等のオートバイのチェノガイ
ドに関する。[Detailed Description of the Invention] This invention relates to a cheno guide for a motorcycle such as a motocross type.
オートバイは、クッションユニットを増付ｒｒｙ ＊揺
動可能なスイングアームの後端に後輪を取着し、エンジ
ンのスプロケットと後輪のスプロケットなチェノによっ
て駆動している。The motorcycle is equipped with a cushion unit. *The rear wheel is attached to the rear end of the swing arm, which can swing, and is driven by the engine sprocket and the rear wheel sprocket.
そして、山地でレースを行うモトクロス型オートバイで
は、路面の凹凸が多いので、これに合せてクッションス
トロークも大きくする。Furthermore, since motocross motorcycles race in mountainous areas, the road surface is often uneven, the cushion stroke is also increased accordingly.
ところがクッションに伴ってチェノも振動して、スプロ
ケットから外れ易くなる。However, due to the cushion, the cheno also vibrates, making it easier for it to come off the sprocket.
このためガイドローラでチェノを支えている。しかし、
この種のオートバイは、坂道等の状況に合せて、スプロ
ケットが歯数の異るものと交換して、減速比を路面に合
せる作業をレース前に行うが、このとき、ガイドローラ
も多数用意して、スプロケットの交換に合せて交換しな
ければならず、部品点数が多くなるとともに手数がかか
る。For this reason, the cheno is supported by guide rollers. but,
Before a race, the sprocket of this type of motorcycle is replaced with one with a different number of teeth to match the speed reduction ratio to the road surface depending on the situation, such as on a slope. At this time, a large number of guide rollers are also prepared. Therefore, the sprocket must be replaced when the sprocket is replaced, which increases the number of parts and takes time.
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 an embodiment of the invention shown in the drawings will be described below.
前端を車体１に軸２で揺動自在に軸着し、後部にクッシ
ョンユニット８を連結したスイングアーム４の後端に後
車軸５を取着する。A rear axle 5 is attached to the rear end of a swing arm 4 whose front end is swingably attached to a vehicle body 1 with a shaft 2 and a cushion unit 8 is connected to the rear end.
そして、エンジンのスプロケット６と後輪７をチェノ８
で連結して駆動する。Then, connect the engine sprocket 6 and rear wheel 7 to the Cheno 8
are connected and driven.
而して本考案は、スイングアーム４の後下部に左右二枚
の保持板９をボルト１０で取着して垂下させる。Accordingly, in the present invention, two left and right holding plates 9 are attached to the rear lower part of the swing arm 4 with bolts 10 and are suspended.
保持板９には前部に軸孔１１を設け、後部に長孔１２を
設ける。The holding plate 9 is provided with a shaft hole 11 in the front part and a long hole 12 in the rear part.
ガイド舌片１３は細長く耐摩耗性が強いナイロン等の合
成樹脂で成形したもので、前部を軸１４で軸孔１１に回
動自在に取着し、後端に挿通したボルト１５を長孔１２
に位置調節可能に取着する。The guide tongue piece 13 is elongated and molded from synthetic resin such as nylon, which has strong wear resistance.The front part is rotatably attached to the shaft hole 11 with a shaft 14, and the bolt 15 inserted through the rear end is attached to the long hole. 12
The position can be adjusted.
そして、ガイド舌片１３の上面にチェノ８を沿わせる。Then, the chino 8 is placed along the upper surface of the guide tongue piece 13.
作用について説明する。The effect will be explained.
スプロケット６又は後輪スプロケットγを交換したり、
チェノ８が使用によって伸びたりすると、チェノ８が張
ったり弛んだりする。Replace sprocket 6 or rear wheel sprocket γ,
When the Cheno 8 stretches due to use, the Cheno 8 becomes stretched or loosened.
このとき、ボルト１５を弛めて長孔１２に沿ってガイド
舌片１３を回動させ、チェノ８の張りを調節する。At this time, the tension of the chino 8 is adjusted by loosening the bolt 15 and rotating the guide tongue piece 13 along the elongated hole 12.
チェノ８はこうして張りが調節され、スイングアーム４
が揺動しても振動を少くでき、後輪スプロケット７の噛
合位置にガイド舌片１３によって案内され外れることが
防止できる。The tension of the Cheno 8 is adjusted in this way, and the swing arm 4
Even if the rear wheel sprocket 7 swings, the vibration can be reduced, and the guide tongue piece 13 guides the rear wheel sprocket 7 to the meshing position and prevents it from coming off.
以上説明したように、この考案は、スイングアームの下
方に垂下させた保持板に軸孔と長孔を設け、細長いガイ
ド舌片の前部を軸孔に軸で回動自在に取着し、ガイド舌
片の後端を長孔に位置調節可能に取着し、ガイド舌片の
上面に後輪スプロケットを駆動するチェノを沿わせるよ
うにしたので、ガイド舌片を長孔に沿って回動させるこ
とによって、チェノの張りを調節でき、スプロケットの
交換に合せて短時間でチェノの張り具合を調節でき、手
間が省ける。As explained above, in this invention, a shaft hole and a long hole are provided in the holding plate suspended below the swing arm, and the front part of the elongated guide tongue is rotatably attached to the shaft hole. The rear end of the guide tongue is attached to the long hole so that its position can be adjusted, and the chain that drives the rear wheel sprocket is placed along the top surface of the guide tongue, so the guide tongue can be rotated along the long hole. By doing so, you can adjust the tension of the cheno, and when replacing the sprocket, you can adjust the tension of the cheno in a short time, saving you time and effort.
