本発明は、オートバイの後輪カウリングに関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a motorcycle rear wheel cowling.
オートバイで、ロードレースに用いるものや、
高速走行用のものでは、車体前部に前面カウリン
グを取付け、風の乱流による抵抗を少くしてい
る。一般に、前面カウリングは、上端にスクリー
を取付け、車体の側面まで伸び、下側はエンジン
の下方まで覆う形状になつている。前面スクリー
ンが、エンジンの下側を覆うところまでであるの
で、後輪の回転によつて、前面カウリングの下側
後端と後輪の前下端の間に、風の渦流ができて、
抵抗になる。 Motorcycles used for road races,
For high-speed vehicles, a front cowling is attached to the front of the vehicle to reduce resistance from wind turbulence. Generally, a front cowling has a scree attached to its upper end, extends to the side of the vehicle body, and has a lower part that covers the engine below. Since the front screen covers the lower side of the engine, the rotation of the rear wheels creates a vortex of wind between the lower rear end of the front cowling and the front lower end of the rear wheel.
Become resistance.
本発明は、かかる点に鑑み、後輪カウリングを
設けて、前面カウリングと後輪との間の風の渦流
発生を防ぎ、抵抗を少くして高速で走行できるよ
うに改善したもので、以下本発明を図面に示す実
施例について説明する。 In view of these points, the present invention provides an improved rear wheel cowling to prevent wind vortex generation between the front cowling and the rear wheel, thereby reducing resistance and enabling high speed running. An embodiment of the invention illustrated in the drawings will be described.
後輪カウリング１は、横断面が深い樋状で、側

ラツプするように挿入する。後輪カウリング１
は、後ホーク３と共にクツシヨンして揺動したと
き、前面カウリング４に当らないように、前面カ
ウリング４との間に、適宜隙間を設ける。 The rear wheel cowling 1 is molded from a light alloy plate, synthetic resin, or the like, and has a deep gutter-like cross section and a substantially parallelogram-like side surface. Rear wheel cowling 1
are arranged so as to cover the front lower part of the rear wheel 2 of the motorcycle, and the left and right upper edges are connected to the rear fork 3 by screws or the like. The front part of the rear wheel cowling 1 is inserted inside the rear lower end of the front cowling 4 so as to overlap with the front cowling 4. Rear wheel cowling 1
An appropriate gap is provided between the front cowling 4 and the front cowling 4 so that the front cowling 4 does not hit the front cowling 4 when the rear fork 3 cushions and swings.
次に本実施例の作用について説明する。 Next, the operation of this embodiment will be explained.
前面カウリング４の後下端と、後輪カウリング
１とは、流線で接続され、後輪カウリング１は、
後輪２の前下部を覆つて、後輪２の回転による、
風の渦流を遮断する。このため、前面カウリング
４の下面に沿つて流れた風は、引続き後輪カウリ
ング１に沿つて後方に流れることができ、前面カ
ウリングの後下端後側に乱流が発生することがな
く、走行抵抗が低減できる。 The rear lower end of the front cowling 4 and the rear wheel cowling 1 are connected by a streamline, and the rear wheel cowling 1 is
Covering the front lower part of the rear wheel 2, due to the rotation of the rear wheel 2,
Blocks wind eddies. Therefore, the wind that has flowed along the lower surface of the front cowling 4 can continue to flow rearward along the rear wheel cowling 1, and turbulence does not occur behind the rear lower end of the front cowling, reducing running resistance. can be reduced.
以上説明したように、本発明は、断面樋状で側

け、該後輪カウリングを後輪の前下部に配置して
上端を後ホークに連結し、後輪カウリングの前部
を前面カウリングの後下端内側に挿入するように
したので、前面カウリングの後下部に続けて、後
輪に可及的に接近させて後輪カウリングが設けら
れ、前面カウリング下部から後輪の前下部まで流
線形のカウリングで覆われて、前面カウリングの
後下部に渦流による乱流が発生するのを防ぐこと
ができる。こうして、風の流れが流線にできて、
風による抵抗を少くすることができ、高速走行が
できる。 As explained above, the present invention provides a rear wheel cowling having a gutter-like cross-section and a substantially parallelogram-shaped side surface, and the rear wheel cowling is arranged at the front lower part of the rear wheel, and the upper end is connected to the rear fork. Since the front part of the rear wheel cowling is inserted inside the rear lower end of the front cowling, the rear wheel cowling is installed as close to the rear wheel as possible following the rear lower part of the front cowling, and the front cowling A streamlined cowling covers from the lower part to the front lower part of the rear wheel, which can prevent turbulence caused by vortices from occurring at the rear lower part of the front cowling. In this way, the flow of the wind becomes streamlined,
It can reduce wind resistance and allow high-speed running.
