【発明の属する技術分野】
本発明は、トラック等の貨物自動車の吸気ダクトに関し、更に詳しくは走行時の風圧を利用して、加圧空気をエンジンに供給するよう形成した貨物自動車の吸気ダクトに関するものである。
【０００２】
【従来の技術】
大型トラック等の貨物自動車において、エンジンに外気を導くための吸気ダクトは、通常、運転室の後方空間部を上下に延びており、その上端部に空気取入口を有し、下端部はエアクリーナに連結されている（例えば、特許文献１及び特許文献２参照）。従って従来は、通常、吸気ダクトの上端の空気取入口から外気が取り入れられ、エアクリーナを介してエンジン内に吸入されるものであった。

【発明が解決しようとする課題】
ところでディーゼルエンジンを搭載した大型トラック等にあっては、空気の充填効率を高めることがエンジン性能を高める上で望ましい。
【０００５】
しかるに従来品は、上記の通り、吸気ダクトの上端の空気取入口から外気を取り入れる構造であったから、従来品によると空気がエンジン内に充分に供給されず、パワー不足を生じたり、黒煙を発生したりする原因となっていた。
【０００６】
本発明は、このような従来の問題点に鑑み、提案されたものである。
従って本発明の技術的課題は、空気の充填効率を高め、エンジン性能を向上できる貨物自動車の吸気ダクトを提供することにある。
【０００７】
【課題を解決するための手段】
本発明は、上記の課題を解決するために、次のような技術的手段を採る。
【０００８】
即ち本発明は、図１等に示されるように、エアクリーナ３に連結されている貨物自動車の吸気ダクト１であって、エアクリーナ３に連結されて運転室４の後方部を上方に延びる縦ダクト部分１ａと、この縦ダクト部分１ａの上端から運転室４の屋根５上を前方に延び前方を向いた空気取入口６を先端に有する横ダクト部分１ｂとで形成され、この屋根５上の横ダクト部分１ｂの後部下面に水抜き孔７が設けられていることを特徴とする（請求項１）。
【０００９】
上記の構成によれば、外気が、走行時の風圧により、吸気ダクト１内に押し込まれ、エンジンに過給されるので、エンジンの空気の充填効率を向上できる。その結果、空気不足による黒煙の発生やパワー不足を解消することができる。
【００１０】
又本発明の場合、空気取入口６が、走行風圧を受けて空気の取入量を調節する調節手段９を備えて形成されているのが好ましい（請求項２）。
【００１１】
なぜなら、走行時の風圧が高くなり、過給が必要以上に行われると、かえってエンジン性能の低下を来たすため、空気取入口６を正面から見たときの開口面積を走行時の風圧に応じて調節できるようにするのが好ましいからである。
【００１２】
また、本発明は、屋根上の横ダクト部分１ｂが内部を仕切壁１５で仕切られて前後に延びる導風路１６を左右に複数有しているのが好ましい（請求項３）。
【００１３】
なぜならこれによれば、吸入空気を整流でき、圧力の損失を防ぐことができるからである。
【００１４】
また本発明は、導風路１６の長手方向と直交する方向の断面が略三角形状に形成されているのが好ましい（請求項４）。
【００１５】
なぜならこれによると、導風路１６を流れる空気は上部で流速が高く、下部で流速が低くなるので、空気中に含まれている水滴が落下し易くなるからである。
【００１６】
又本発明は、屋根上の横ダクト部分１ｂの先端部の下面に、空気取入口１９を備えて形成されているのが好ましい（請求項５）。
【００１７】
なぜならこれによれば、前方に開口している空気取入口６にフィルタを装着した場合、フィルタに雪や虫等が詰まり空気取入口６が塞がっても、下面の空気取入口１９から空気を取り入れることができるからである。
【００１８】
【発明の実施の形態】
以下、本発明の好適な一実施形態を添付図面に従って説明する。
【００１９】
図１等において、１は、外気をトラック２のディーゼルエンジン内に導入するための吸気ダクトである。この吸気ダクト１は、エンジンの吸気側に接続しているエアクリーナ３に連結されて運転室４の後方部を上方に延びる縦ダクト部分１ａと、この縦ダクト部分１ａの上端から運転室４の屋根５上を前方に延び前方を向いた空気取入口６を先端に有する横ダクト部分１ｂとで形成され、この屋根５上の横ダクト部分１ｂの後部下面に水抜き孔７が設けられている。
【００２０】
８は、吸気ダクト１の空気取入口６に設けられているフィルタである。このフィルタ８は、例えばステンレス製の金網からなっており、上部が前方に少し傾斜して取り付けられている。９は、走行風圧を受けて空気の取入量を調節する調節手段である。この調節手段９は、吸気ダクト１の空気取入口６に設けられ、空気取入口６の開口と略同じ大きさの遮蔽板１０と、錘板１１とを備えて形成されている。遮蔽板１０と錘板１１は、互いに略直角をなすよう、空気取入口６の上端に横向きに設けられている回動軸１２に取り付けられている。又遮蔽板１０と錘板１１は、風圧を受けないときは、図１に示されるように、錘板１１が垂直に垂れ下がり、遮蔽板１０は略水平に配置される。そして一定値以上の風圧を受けると、図３及び図４に示されるように、錘板１１が後方に回動し、遮蔽板１０がそれに伴い後方に回動して空気取入口６を正面から見て遮蔽状に配置される。この調節手段９は、例えば時速と向風の風速との和が、１００ｋｍ／時以上で作動するように構成される。
【００２１】
１３は、空気の流れを整流するための整流部材であり、吸気ダクト１の屋根５上の横ダクト部分１ｂの内部に装着されている。この整流部材１３は、図８に示されるように、内部に空洞を有する箱状部材であり、吸気ダクト１の内部に装着された状態で吸気ダクト１の底面との間に隙間１４が形成される。又この整流部材１３は、内部が仕切壁１５で仕切られて前後に延びる導風路１６を左右に複数備えて形成されている。仕切壁１５は、逆三角形断面に形成され、導風路１６は長手方向と直交する方向の断面が略三角形状に形成されている。又整流部材１３は、各導風路１６の底面に前後に延びるスリット１７を有しており、各導風路１６を通過する空気中の水滴がこのスリット１７から隙間１４内に落下するよう形成されている。この場合、この実施形態に係る本発明では、断面が略三角形状の導風路１６では上部の方が下部より断面積が小さいため、上部で流速が速く下部で流速が遅くなり、空気中の水滴が落下し易くなっている。
【００２２】
１８は、落下した水を水抜き孔７まで案内するための溝である。この溝１８は、屋根５上の横ダクト部分１ｂの内部底面に形成され、空気取入口６から水抜き孔７まで前後に延びており、後方に向かって少し下り勾配に形成されている。従って整流部材１３より手前の部分や整流部材１３から落下した水滴は溝１８に入り、溝１８内を流れて後端部の水抜き孔７から外部へ排出される。
【００２３】
又横ダクト部分１ｂは、この実施形態ではその先端部が運転室４の屋根５より少し前方に突き出されて配置され、この先端部の下面に空気取入口１９が形成されている。２０は、下面の空気取入口１９に設けられているフィルタである。このフィルタ２０は、例えばステンレス製の金網で形成されている。
【００２４】
以下、本発明の作用を説明する。
【００２５】
本発明の場合、外気はトラック２の走行中、吸気ダクト１の空気取入口６から取り入れられ、エアクリーナ３で清浄にされてディーゼルエンジン内に吸入される。この際、外気はトラック２の走行時の風圧によってエンジンに過給され、エンジン内の空気の充填率が高まるため、本発明によるとパワー不足や黒煙の発生等の問題が解消される。一方、外気に含まれている水は、横ダクト部分１ｂ内を通過中に落下してその底面の溝１８を後方に流れて水抜き孔７から外部に排出される。
【００２６】
又、万が一、前方を向いている空気取入口６のフィルタ８が雪や虫等で詰まり、空気取入口６が塞がれた場合には、横ダクト部分１ｂの先端部の下面に形成されている空気取入口１９を通じて外気が吸気ダクト１内に取り入れられる。
【００２７】
【発明の効果】
以上説明したように本発明の吸気ダクトは、エアクリーナに連結されて運転室の後方部を上方に延びる縦ダクト部分と、この縦ダクト部分の上端から運転室の屋根上を前方に延び前方を向いた空気取入口を先端に有する横ダクト部分とから構成されている。

Or cause it to occur.
[0006]
The present invention has been proposed in view of such conventional problems.
Therefore, a technical problem of the present invention is to provide an air intake duct for a lorry that can increase the air filling efficiency and improve the engine performance.

A drain hole 7 is provided on the rear lower surface of the portion 1b (claim 1).
[0009]
According to the above configuration, the outside air is pushed into the intake duct 1 by the wind pressure during traveling and is supercharged to the engine, so that the efficiency of charging the engine with air can be improved. As a result, generation of black smoke and power shortage due to air shortage can be eliminated.
[0010]
Further, in the case of the present invention, it is preferable that the air inlet 6 is provided with adjusting means 9 for adjusting the amount of air taken in by receiving the traveling wind pressure (claim 2).
[0011]
Because, when the wind pressure at the time of traveling increases and the supercharging is performed more than necessary, the engine performance is rather deteriorated. Therefore, the opening area when the air inlet 6 is viewed from the front is determined according to the traveling wind pressure. It is preferable to be able to adjust.
[0012]
Further, in the present invention, it is preferable that the lateral duct portion 1b on the roof has a plurality of left and right air guide paths 16 which are partitioned by a partition wall 15 and extend forward and backward (claim 3).
[0013]
This is because, according to this, intake air can be rectified, and pressure loss can be prevented.
[0014]
Further, in the present invention, it is preferable that a cross section in a direction orthogonal to the longitudinal direction of the air guide path 16 is formed in a substantially triangular shape.
[0015]
This is because, according to this, the air flowing through the air guide passage 16 has a high flow velocity in the upper part and a low flow velocity in the lower part, so that water droplets contained in the air easily fall.
[0016]
Further, in the present invention, it is preferable that the lower surface of the front end portion of the lateral duct portion 1b on the roof is provided with an air inlet 19 (claim 5).
[0017]
According to this, when a filter is mounted on the air inlet 6 opening forward, air is taken in from the air inlet 19 on the lower surface even if the filter is clogged with snow or insects and the air inlet 6 is closed. Because you can do it.
[0018]
