'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.

Here, the front end of the guide member 47 is located in front of the air inlet i8a of the air cleaner 18, and the rear end of the guide member 47 is located behind the air inlet 18a of the air cleaner 18. Therefore, the guide member 47 Cover it so as to pass the entire length of the suction port 1 ″ of the air cleaner 18. As shown in FIG. 5, the width dimension of the guide member 47 is set to be larger than the width of the air suction port 18 a of the air cleaner 18. It is large in size and is covered by the guide member 47 so as to pass the full width of the suction port 18a or more. The guide member 47 is 'viewed from the side' and is installed so as to face the suction port of the air cleaner 18 (the vehicle). The rear side of the body is inclined downward. The installation structure of the guide member 47 will be described here. The front end of the guide member 47 is a link-shaped portion 47a that partially forms a gap, as shown in Figs. 3 and 4. The link-shaped portion 47a is embedded in the rear support bar. 8. The periphery is fastened to the outer periphery of the rear support bar 8 by means of a band 48. Furthermore, a side view triangular mounting portion 47b is integrally formed on the outer surface of the rear portion of the guide member 47, so that a protrusion protruding on the inner surface of the upper end of the mounting portion 47b is protruded. 47c by embedding The rear member of the guide member ... is fixed to the connecting member 26 by means of a circular hole (not shown) formed in the connecting member 26. On the other hand, as shown in FIG. In the rear direction, between the air inlet 18a and the rear end of the aforementioned guide member 47, the rib-shaped water stop wall 18b is formed to be inclined downward toward the front of the vehicle body. In this embodiment, the air cleaner 18 is covered The suction duct 18 & upper water-guiding guide member 47 is installed on the rear support bar 8 directly above the suction port 18a, and even if water such as water spray splashed from the rear wheel 17 runs along the rear support bar 8 585968

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

從以上說明得知,依據本發明,機車中,將新氣導入空 氣清淨器淨化後,將該新氣供給於形成混合氣,前述空氣 清淨器之吸氣口正上方管路框體安裝有導水管形引導構件 ’由於藉由該引導構件覆蓋空氣清淨器之吸氣口上方,因 此可確實地防止水滲入空氣清淨器,同時可獲得降低吸氣 阻力而達成提高引擎性能之效果。 [圖式簡單說明] 圖1為速克達型機車側視圖。 圖2為速克達型機車之部分前剖視圖。 圖3為速克達型機車之空氣清淨器部分之側視圖。 圖4為圖3之A-A線剖視圖。 圖5為圖3之B-B線剖視圖。 圖6為空氣清淨器立體圖。From the above description, according to the present invention, in a locomotive, after introducing fresh air into an air cleaner for purification, the fresh air is supplied to form a mixed gas, and a duct frame is installed directly above the air inlet of the air cleaner. The water pipe-shaped guide member 'covers the upper part of the air cleaner's intake port with the guide member, so that water can be reliably prevented from penetrating into the air cleaner, and at the same time, the effect of improving the engine performance can be achieved by reducing the suction resistance.
