【考案の詳細な説明】
この考案は、オートバイのエヤクリーナ吸入音低減装置
に関する。[Detailed Description of the Invention] This invention relates to an air cleaner intake noise reduction device for a motorcycle.
オートバイは、気化器の先にエヤクリーナを設けて、清
浄空気をエンジンに供給している。Motorcycles are equipped with an air cleaner at the end of the carburetor to supply clean air to the engine.
エンジンの吸気は、間歇的に行われその都度吸入騒音を
発生する。The intake air of the engine is performed intermittently and generates intake noise each time.
この吸入騒音は、エヤクリーナの容積を大きくして、流
速を緩和させれば少くできるが、オートバイの場合、エ
ヤクリーナを装着するスペースに限りがあって、容積を
大きくすることに限界があるので、吸入騒音を少くし難
い。This suction noise can be reduced by increasing the volume of the air cleaner and reducing the flow velocity, but in the case of motorcycles, there is limited space to install the air cleaner, and there is a limit to increasing the volume. Difficult to reduce 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 an embodiment of the invention shown in the drawings will be described below.
エンジン１の吸気孔２に気化器３を連結し、気化器３０
入口を吸入管４を介してエヤクリーナ５に連結する。A carburetor 3 is connected to the intake hole 2 of the engine 1, and the carburetor 30
The inlet is connected to an air cleaner 5 via a suction pipe 4.
エヤクリーナ５は、一側に入口６があり、内部にクリー
ナエレメントがあって、入口６かも吸入した空気をクリ
ーナエレメントで浄化し、出ロアに流す。The air cleaner 5 has an inlet 6 on one side and a cleaner element inside, and the cleaner element cleans the air sucked in through the inlet 6 and flows it to the outlet lower.
而して本考案は、エヤクリーナ５０入口６を、側面の一
側に突出させる。Accordingly, in the present invention, the air cleaner 50 inlet 6 is made to protrude to one side of the side surface.
エヤクリーナ５は、車体８の中央に装着され、車体８の
中央は、車体カバー９で覆う。The air cleaner 5 is attached to the center of a vehicle body 8, and the center of the vehicle body 8 is covered with a vehicle body cover 9.
そして、入口６を突出した側の車体カバー９の内面に発
泡体等の吸音材１０を添着する。Then, a sound absorbing material 10 such as a foam material is attached to the inner surface of the vehicle body cover 9 on the side from which the inlet 6 protrudes.
尚１１はシート、１２は燃料タンクを示す。Note that 11 represents a seat, and 12 represents a fuel tank.
作用について説明する。The effect will be explained.
エンジン１が間歇的に早い速度で、空気を吸入すると、
エヤクリーナ５の開放口である入口６から騒音を発する
。When engine 1 intermittently takes in air at a high speed,
Noise is emitted from an inlet 6 which is an open port of an air cleaner 5.
入口６は、車体カバー９内に突出しており、吸音材１０
が、入口６０周りに張設されていることになるので、こ
の入口６付近で大きい吸気騒音を吸音材１０で吸収し、
騒音を低減できる。The inlet 6 protrudes into the vehicle body cover 9 and has a sound absorbing material 10.
is installed around the inlet 60, so the sound absorbing material 10 absorbs the large intake noise near the inlet 6,
Can reduce noise.
以上説明したように、この考案は、出口を気化器に連結
したエヤクリーナの入口を一方の側面に突出させ、車体
の中央側面を覆う車体カバーの内側に入口を向け、車体
カバーの内面に吸音材を添着したので、エヤクリーナの
吸気騒音の高い入口が、吸音材に囲まれるようになり、
吸気騒音を吸音材が吸収して、吸入騒音を低減すること
ができる。As explained above, this idea involves making the inlet of the air cleaner whose outlet is connected to the carburetor protrude from one side, directing the inlet toward the inside of the car body cover that covers the central side of the car body, and using sound-absorbing material on the inner surface of the car body cover. Since the air cleaner is attached, the inlet of the air cleaner, which has a high level of intake noise, is now surrounded by sound-absorbing material.
The sound absorbing material absorbs the intake noise, thereby reducing the intake noise.
そして、エヤクリーナを、容積を大きくせずに吸入騒音
の低減が計れる。In addition, suction noise can be reduced without increasing the volume of the air cleaner.
又、吸音材は、車体カバーの内面に添着するので、場所
をとらない。Furthermore, since the sound absorbing material is attached to the inner surface of the vehicle body cover, it does not take up much space.
こうして、小型でオートバイのようにスペースの小さい
ものに最適である。As such, it is small and ideal for small spaces such as motorcycles.
