【発明の詳細な説明】
〔産業上の利用分野〕
この発明は、オートバイのカウリングの導風装置に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a wind guide device for a cowling of a motorcycle.
オートバイは、車体の前部をカウリングで覆って風の抵

している。例えば、特開昭６１−１２５９２１号公報、
実開昭６１−２４３１６号公報参照。Motorcycles sometimes have a cowling covering the front of the body to reduce wind resistance. In this case, the engine mounted at the front of the vehicle body is cooled by receiving wind from driving through the air outlet provided at the front of the cowling. For example, Japanese Patent Application Laid-open No. 125921/1983,
See Utility Model Application No. 61-24316.

ド部分が、オイルクーラーの後側になり、冷却風が十分
に当らない不都合がある。The oil cooler is placed above and in front of the slightly forward-leaning cylinder and cylinder head of the engine, and the lubricating oil is cooled by directing the air received from the front air guide port of the cowling to the oil cooler. There are things to do. In this case, the cylinder head of the engine is located at the rear of the oil cooler, which is disadvantageous in that it is not sufficiently exposed to cooling air.

とを目的とする。In view of this, this invention provides an oil cooler above the front of the engine, which can improve the cooling effect by separately sending the air received during driving toward the cylinder head of the engine. The purpose is to obtain equipment.

イド板を連結するようにしたことにある。In order to achieve the above object, the motorcycle cowling air guide device of the present invention covers the front part of the vehicle body with a cowling, mounts the engine in the front part of the vehicle body, and has an oil cooler facing forward above the front of the engine. Installed, the oil cooler and engine are cooled by receiving wind from driving through the air guide port provided on the front of the cowling. Side air guide ports are opened on the left and right sides of the cowling below the oil cooler. The reason is that a guide plate is connected to the rear side to deflect the wind received upward.
オートバイを走行させると、カウリングの前面に設けた
導風口から走行によって受ける風か入り、オイルクーラ
ー及びエンジンに当って冷却できる。When the motorcycle is running, the wind from the riding enters through the air outlet provided on the front of the cowling and cools the oil cooler and engine.
しかし、エンジンの上部のオイルクーラーの後側になる
部分は、オイルクーラーの冷却で温められた風が当り、
十分な冷却かできない。カウリング側面のオイルクーラ

却を促進する。However, the part behind the oil cooler at the top of the engine is exposed to the air heated by the oil cooler.
It just can't cool down enough. The wind received while driving enters the side air guide hole provided below the oil cooler on the side of the cowling, is deflected upward by the guide plate, and flows towards the top of the engine behind the oil cooler, promoting cooling of the top of the engine. .
以下、本発明の実施例を図面によって説明する。 Embodiments of the present invention will be described below with reference to the drawings.

けて曲げである。The front part of the vehicle body is covered with a cowling 2 to reduce wind resistance. Engine 3 is mounted at the lower front of the vehicle body, with the cylinder facing upward and slightly tilted forward. or,
At the upper part of the down tube 4 of the vehicle body, above the front of the engine 3, an oil cooler 5 is installed facing forward, and the lubricating oil of the engine 3 is circulated and cooled. A large air guide port 6 is provided on the front surface of the cowling 2. The air guide port 6 accepts the wind received when the vehicle is running, and cools the oil cooler 5 and the engine 3 by applying it to the wind. At the rear of the oil cooler 5 on both sides of the cowling 2, exhaust lowers are provided so that moist air from cooling the oil cooler 5 can escape. Side air guide ports 8 are opened at the front portions of the left and right sides of the cowling 2 at positions below the oil cooler 5. Then, a guide plate 9 is connected to the rear side of the side air guide port 8. The guide plate 9 is bent with its rear portion facing upward.
側面導風口８から入った走行で受ける風は、ガイド板９

ーラー５の後側になる部分に集中して流れて冷却する。The wind that enters from the side air guide port 8 and is received while driving is passed through the guide plate 9.
The oil is deflected upward by the engine 3 and flows concentratedly to the rear side of the oil cooler 5 at the upper part of the engine 3 to cool it.

を促進させることができる。As explained above, since the present invention is constructed as described above, the oil cooler is installed separately at the top of the engine where it is difficult to receive the wind flowing in from the front air guide port of the cowling and hitting the oil cooler while the vehicle is running. The guide plate directs the wind received from the vehicle through the side air vents on both sides, helping to cool the upper part of the engine.
