Abstract

<P>PROBLEM TO BE SOLVED: To provide a traveling wind entrainment preventive plate for preventing floating of a vehicle by air pressure difference during high-speed traveling of the vehicle. <P>SOLUTION: A protective plate 2 is mounted between front and rear tires at both sides of the lower surface of the vehicle 1 to prevent entrainment of traveling wind to below the vehicle. According to this, a negative pressure area is generated below the vehicle to enhance the safety in high-speed traveling. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、車両走行時における車両下面への巻き込み風の防止に関するものである。The present invention relates to prevention of a wind that is caught on the lower surface of a vehicle when the vehicle is running.

従来の空力パーツは、車両における高速走行安定性を保つ為に車両前後に取り付けているが、側面よりの空気に対する制御は本格的に行われていない。
各自動車メーカーでは、この車両下面の研究が盛んで参考にした特許広報及び文献は

Each automobile manufacturer has a lot of research on the underside of the vehicle.

自動車などが走行時にその前面で空気を押し分け、その空気が再び収束しようと車体に押し寄せる、この空気脈動が空気抵抗や車両をリフトさせる原因になっている。
車両下面において前輪、後輪の内側部において負圧は生じているが、前後輪の中間部に左右よりの収束風が交わり車両中心部で、空力的に正圧となって車両を押し上げる。
本発明は、この収束風の車両下面への流入を防ぐ防御板である。When an automobile or the like travels, it pushes air in front of it, and the air pulsation pushes it toward the vehicle body to converge again. This air pulsation causes air resistance and lift of the vehicle.
Although negative pressure is generated on the inner surface of the front and rear wheels on the lower surface of the vehicle, a convergent wind from the left and right intersects with the middle portion of the front and rear wheels, and the vehicle is aerodynamically positive and pushes up the vehicle.
The present invention is a protective plate that prevents the convergent wind from flowing into the lower surface of the vehicle.

Means to solve the problem

車両前面下部で押し開けられ左右に広がった空気が前輪後方部に向かって収束しようとする空気を車両プラットホーム底面左右の前後タイヤ間に［図１］の防御板▲２▼を取り付ける。A barrier plate (2) shown in FIG. 1 is attached between the front and rear tires on the left and right sides of the bottom of the vehicle platform.

The invention's effect

この発明の防御板を取り付ける事により走行中、車両下面中央に発生している正圧域を負圧域に変換し、従来より発生している前輪、後輪内側の負圧域と繋げることが出来る。これにより車両下面全体を負圧域とする事により、高速走行時に大気圧によって車両全体をバランスよく押し付ける力が発生する。
上記の事柄により、具体的な走行車両への効果として挙げられることは、
１、直進及びカーブでの安定性の向上。２、ブレーキ時の制動力及び安定性の向上。３、既存の空力パーツのように空気抵抗を増やす事も無いので、車の動力性能を上げ燃費も向上する。By attaching the protection plate of the present invention, during traveling, the positive pressure region generated at the center of the lower surface of the vehicle can be converted into the negative pressure region, and connected to the negative pressure region inside the front wheel and the rear wheel generated conventionally. I can do it. Thus, by setting the entire lower surface of the vehicle to a negative pressure region, a force is generated that presses the entire vehicle in a well-balanced manner by atmospheric pressure during high-speed traveling.
Due to the above, what can be mentioned as a specific effect on a traveling vehicle is
1. Improving stability in straight line and curve. 2. Improvement of braking force and stability during braking. 3. Since there is no need to increase the air resistance like existing aerodynamic parts, the power performance of the car is improved and the fuel efficiency is improved.
