Abstract

This invention provides a waterproof structure of a motorcycle air filter to positively prevent the invasion of the water into an air filter while reducing inhalation resistance to thereby enhance engine performance. In a motorcycle, after purifying fresh air is introduced to the air filer 18, the fresh air is supplied to form a mixed flow. On a rear support (pipe frame) 8 provided above an air inlet 18a of the air filter 18 is mounted with a water gutter 47, such that the water gutter 47 covers above the air inlet 18a of the air filter 18. According to this invention, even if water flows to the front of the motorcycle along the rear support 8, this water drips into the water gutter 47 without being sucked into the air inlet 18a of the air filter 18 so as to ensure high waterproof characteristic of the air filter 18. In addition, it is not necessary to open the inlet 18a towards the side or downwards in order to prevent the invasion of the water to the air filter 18. The outer cover covers the air inlet 18a itself to reduce inhalation resistance low and to improve engine performance.

'There will be water along the front of the frame body, staying close to the air intake, and starting from the air. Mouth leaks into the air cleaner. The air intake σ of the outer purifier is opened horizontally or downward, or the invention has developed a waterproof structure for a locomotive air purifier to solve the above-mentioned problems. The air purifier can be inserted into the air purifier and the air intake resistance can be reduced. "Go ::: The body's conventional waterproof structure has the problem that the suction resistance is large and the engine performance cannot be fully exerted. The purpose is to achieve the lifting bow for the purpose of reliably preventing water | Solution to the problem] (2) (2) 585968 In order to achieve the above purpose, in the locomotive applying for the first invention of the patent scope, the fresh air is introduced into the air cleaner for purification, and then the fresh air is supplied to form a mixed gas, which is characterized by: The pipe frame member directly above the air inlet of the air cleaner = is equipped with a water guiding tube-shaped guide member, and the guide member covers the air cleaner above the air inlet of the air cleaner. The second invention, the scope of patent application In the old invention, the front end of the guide member is located at a position ahead of the air inlet of the air cleaner, and the rear end of the guide member is located at a position behind the air inlet of the air cleaner. The third invention in the scope of patent application is the first in the scope of patent application! The second or the first one is clear! ^ From the side, the aforementioned guide member is installed so as to be inclined toward the reverse side of the air inlet of the air cleaner and downward. The fourth invention claimed in the patent scope is the patent scope ^, the second or the third invention, in which the front and rear directions of the vehicle body of the side wall of the air cleaner are behind the air inlet and the guide member. A water stop is formed between the ends. :: The invention in the scope of the patent claim, because the air is covered and the water pipe "road frame part" above the nipple is covered, even if the water ball and other water puffed out by the rear wheel and: :: = Body: Fang, the water will also be dripped by the guide member, and the suction port of the cleaner penetrates into the interior of the air cleaner. In order to ensure the high water resistance of the air cleaner. And, there is no need to prevent two! The space-time cleaner adopts a structure in which the suction port is opened horizontally or downward = Yuan Fu covers the suction port itself, so the suction resistance can be controlled ^ 585968 ㈧ to improve engine performance. According to the second invention of the declared patent range, since it can be covered by the entire length of the air cleaner suction port by the guide member, water can be more surely prevented from penetrating into the air cleaner from the suction port. According to the 3rd invention of the patent scope of the patent, 'From the side, the cow's clothing is guided to the opposite side of the air inlet of the air cleaner and inclined downward, so the water recovered by the guide member' will not flow. The suction port of the air cleaner reaches the suction port on the opposite side, thus preventing water from entering the air cleaner from the suction port more surely. According to the fourth invention of the scope of the patent application, even if the water recovered by the guide member drips from the rear end of the guide member to the side wall of the air cleaner, the water is prevented from flowing to the suction port by the water stop wall, so that it is more reliably prevented.

Then, at this time, the water stopper wall 18b formed on the outer side wall of the air cleaner 18 prevents the water dripping on the air cleaner 18 from flowing toward the suction port i 8a, so the water from the suction is reliably prevented Port 18a penetrates the air cleaner 18. In this embodiment, since the guide member 47 covers the entire length and width of the air inlet 18a of the air cleaner 18, it is possible to more reliably prevent water from entering the air cleaner from the air inlet 8a.丨 8. As described above, according to this embodiment, water is prevented from leaking from the air inlet 18a of the air cleaner 18 into the air cleaner 18, thereby ensuring the high water resistance of the air cleaner 18. When the rear suspension engine 14 is started, the fresh air sucked by the negative suction pressure of the engine 15 is introduced into the air cleaner 18 through the suction duct 46 through the suction port 18a. Alas, the fresh air introduced into the air cleaner 丨 8 is purified by a cleaner (not shown), and the air cleaner 18 is led to the carburetor through the suction pipe. Then, in the carburetor 20, gasoline and fresh air are supplied from the fuel tank 13 through the fuel pump 42. The gasoline and fresh air are mixed to form a predetermined air-fuel ratio (a / f), and the δ-hai mixture is supplied to the engine.丨 5 for burning. In this embodiment, it is not necessary to prevent water from penetrating the air cleaner 18: the suction port 18a is opened laterally or downwardly, or the suction port 18a itself is covered by an outer cover, so that so-called Directly inhale, which can reduce the resistance of inhalation and improve the performance of the engine. , Umoto & Ming specifically stated that it is suitable for speed locomotive -12- 585968
