Description
本発明は、走行燃費性能を改善する為の、トラックの箱形荷台に関するものである。TECHNICAL FIELD The present invention relates to a truck box for improving driving fuel consumption performance.
従来のトラックの箱形荷台は、単なる長方形の箱様の姿であった。The conventional truck-type cargo bed of a truck was just a rectangular box-like figure.
そのために走行時には箱型荷台周辺を流れる空気が、荷台の後ろに回り込みにくく、負圧が生じ、走行の抵抗になっていた。For this reason, during traveling, air flowing around the box-type carrier is difficult to go around behind the carrier, and negative pressure is generated, resulting in resistance to traveling.
従来の箱形荷台付きトラックでは、走行時に、荷台の後方に負圧域が生じて、走行の抵抗となっていた。In a conventional truck with a box-type carrier, a negative pressure region is generated behind the carrier during running, resulting in running resistance.
本発明は、走行時に箱型荷台後方に、十分に空気が回り込み、負圧域の発生を抑えて、従来よりも少ない燃料で走行出来る事を目的としている。An object of the present invention is to allow air to sufficiently circulate behind the box-type cargo bed during traveling, suppress the generation of a negative pressure region, and travel with less fuel than before.

本発明による荷台を取り付けたトラックが走行すると、空気取り込み口から入る空気が荷台後の空気排出口から出る事によって、荷台周辺を流れる空気が回り込めなかった荷台後方に、空気を排出・供給する事で、発生する負圧域が、従来技術の箱型荷台に比べて少ないので、従来より走行に対する抵抗が減少し、少ない燃料で走行できると言う効果を発揮するものである。When a truck equipped with a loading platform according to the present invention travels, the air entering from the air intake port exits from the air discharge port after the loading platform, so that the air flowing around the loading platform is discharged and supplied to the rear of the loading platform. As a result, since the generated negative pressure region is smaller than that of the conventional box-type loading platform, the resistance to running is reduced compared to the prior art, and the effect of running with less fuel is exhibited.

本発明は、走行燃費性能を改善するための、トラックの箱形荷台に関するものである。TECHNICAL FIELD The present invention relates to a truck box for improving driving fuel consumption performance.
従来のトラックの箱形荷台は、単なる長方形の箱様の姿であった。The conventional truck-type cargo bed of a truck was just a rectangular box-like figure.
そのために走行時には箱型荷台周辺を流れる空気が、荷台の後ろに回り込みにくく、負圧が生じ、走行の抵抗になっていた。For this reason, during traveling, air flowing around the box-type carrier is difficult to go around behind the carrier, and negative pressure is generated, resulting in resistance to traveling.
従来の箱形荷台付きトラックでは、走行時に、荷台の後方に負圧域が生じて、走行の抵抗となっていた。In a conventional truck with a box-type carrier, a negative pressure region is generated behind the carrier during running, resulting in running resistance.
本発明は、走行時に箱型荷台後方に、十分に空気が回り込み、負圧域の発生を抑えて、従来よりも少ない燃料で走行出来る事を目的としている。 An object of the present invention is to allow air to sufficiently circulate behind the box-type cargo bed during traveling, suppress the generation of a negative pressure region, and travel with less fuel than before.
この目的のために、トラックの箱型荷台の後方に、中央付近に穴の開いた、荷台後面と同程度の大きさの板（６）を、荷台との間に一定の隙間を開けて取り付けた。 For this purpose, a plate (6) with a hole around the center and a size similar to the rear of the loading platform is attached to the rear of the truck box loading platform of the truck with a certain gap between it and the loading platform. It was.
従来技術の箱形荷台のトラックでは、走行すると 側面の空気が 荷台後端で 剥離してしまい、空気が荷台後方に回り込めずに、荷台後方に負圧域が発生した。In a conventional box-type truck, the side air was separated at the rear end of the carrier, and the air did not flow around the carrier, creating a negative pressure area behind the carrier.
この問題を解決するために本願発明は、一枚の穴あき板を、荷台との間に隙間を設けて取り付けるだけのシンプルな構造ながら、後方に発生した負圧域が、自身を解消するために必要な空気を、板と荷台の隙間にある空気と、負圧域にある空気との差圧により、板の穴から、板と荷台との隙間の空気を負圧域に引き寄せる事が出来る構造を持ち、走行時に荷台後方に発生した負圧は、荷台を引き寄せてトラックの走行の抵抗になるのではなく、荷台後方に取り付けた板の穴から板と荷台との隙間にある空気を引き寄せる事になります。 差圧により引き寄せられ、板の穴から出てきた空気は、負圧域に拡散して負圧域の中心から負圧を解消する働きをし、その作用は連続するので、穴あき板を取り付けた本願発明の箱形荷台を取り付けたトラックは、従来技術の箱形荷台を取り付けたトラックに比べて、走行時の負圧が少なくなり、走行の抵抗が減少して燃費性能が向上するものであります。 In order to solve this problem, the present invention has a simple structure in which a single perforated plate is attached with a gap between the loading platform and the negative pressure region generated in the rear part eliminates itself. The air in the gap between the plate and the carrier can be drawn from the hole in the plate to the negative pressure region by the differential pressure between the air in the gap between the plate and the carrier and the air in the negative pressure region. The negative pressure generated at the rear of the loading platform during construction does not pull the loading platform and become a resistance to running the truck, but draws the air in the gap between the plate and the loading platform from the hole in the plate attached to the rear of the loading platform. It will be a thing. Air drawn by the differential pressure and coming out of the hole in the plate diffuses into the negative pressure region and works to eliminate the negative pressure from the center of the negative pressure region. The truck with the box-type carrier of the present invention has a lower negative pressure during traveling, and the fuel resistance performance is improved by reducing the driving resistance compared to the truck with the box-type carrier of the prior art. There is.
また、差圧による空気の移動を利用した本願発明では、積極的に空気を取り込む装置が不要なので、通常の車体や荷台から張り出した装置を使って空気を積極的に取り込む必要が無く、その様な装置を持っていないので、張り出した装置による走行抵抗の増加もなく、産業上の利用価値の高い発明である事を要旨としますす。In addition, in the present invention using the movement of air due to differential pressure, there is no need for a device that actively takes in air, so there is no need to actively take in air using a device that protrudes from a normal vehicle body or cargo bed. Since it does not have a new device, the gist is that it is an invention with high industrial utility value without an increase in running resistance due to the overhanging device.
