本発明は、３輪自動車に関し、特にその車体形状に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a three-wheeled vehicle, and particularly to its body shape.
本願出願人は、先に前輪を２輪として車体前部をその両

では車体前部と最高車高部分との間の中挟の車体部分に
おいて車体の断面積が減少し、これが空力抵抗の一層の
低減を図る上での障害となる不都合を伴う。The applicant first formed the front part of the vehicle body into a wide, flat shape with two front wheels and 7-point fenders on both sides, and also created a single rear wheel that extends rearward from the front part of the vehicle body and extends into the middle of the vehicle body. The rear part of the vehicle body is shaped so that the height of the vehicle gradually increases toward the rear, and the rear part of the vehicle body has a high height shape that increases the stability against cross winds. We have proposed a three-wheeled vehicle in which the cross-sectional area of the highest vehicle height part is approximately the same as the cross-sectional area of the wide, flat front of the vehicle body, thereby reducing aerodynamic drag. The cross-sectional area of the vehicle body is reduced in the intermediate portion of the vehicle body between the vehicle and the highest vehicle height portion, which is disadvantageous as it becomes an obstacle to further reducing aerodynamic drag.
即ち、車体に断面積の変化する部分があるとこの部分で
車体の表面に沿って流れる気流に乱れを生じ、空力抵抗

とを特徴とする。The object of the present invention is to provide a five-wheeled vehicle that eliminates such inconveniences, and has two front wheels, and the front part of the vehicle body is formed into a wide flat shape with 7 4 points and 7 ends on both sides. At the same time, in a vehicle in which the rear wheel is one wheel and the vehicle body part extending rearward from the front of the vehicle body is sandwiched between them and the vehicle height is gradually increased toward the rear, the fender and the vehicle height are provided on the side of the vehicle body. A lateral overhang is formed that extends rearward continuously from the seventh ender between the side of the highest vehicle height part of the vehicle body, and the overhang area of the overhang is equal to the vehicle height. The cross-sectional area of each part of the vehicle body from the front part of the vehicle body to the highest vehicle height portion is made substantially constant by decreasing the height as the height increases.

方向を正にして取った。Here, according to the present invention, on the side surface of the vehicle body (1), continuous rearward from the fender (1C) is provided between the seventh ender (1C) and the side surface of the highest vehicle height portion (1d). A side projecting portion (1e) is formed, and the projecting area of the projecting portion (1e) is adjusted, for example, by adjusting the width or height as shown in the figure, in response to an increase in vehicle height. In this way, the cross-sectional area of each part of the vehicle body (1) extending from the front part of the vehicle body (1) where the fender (1C) is disposed and the highest vehicle height portion (1d) is made approximately constant. The wheelbase is 2200mm, and the front wheels (21(
21 wheelbase W is 1300mm and maximum vehicle height H is 1350mm.
A graph plotting cross-sectional views of various parts of the vehicle body (1) of the three-wheeled vehicle of the present invention shown in FIGS. 1 to 3 in mm. 7, and the distance X from the axis of the front wheel (2) is plotted on the horizontal axis with the direction of the arrow in FIG. 2 being positive.

のに対し、断面積が一定となる本発明の場合は空力抵抗
係数が０．３１３に減少されることが確認された。If the overhang (1e) is not provided, the cross-sectional area of the vehicle body (1) is the same as that between the front part (X,..., O) and the highest vehicle height part (X = 1200), as shown by the dotted line in Figure 5. In this case, the aerodynamic drag coefficient decreases between Ta.

のである。The front projected area of this vehicle body (11) is 10.92 x 1 (1'- However, the cross-sectional area of each part of the car body (1) is much smaller than the front projected area, and together with the fact that the cross-sectional area is made constant by the overhang (1e), the aerodynamic drag coefficient is as shown above. It becomes a small value.
因に、４輪自動車ではスポーツカータイプのもので空力
抵抗係数は１４以上になる。Incidentally, among four-wheeled vehicles, those of the sports car type have an aerodynamic drag coefficient of 14 or more.

As shown in FIG. 4, the vehicle compartment (1b) is constructed in a cylindrical monohook structure having an example of a side sill (4) and a relatively tall side member (5) on the other side. A gull-wing door (6) covering the passenger compartment (1b) is pivotally attached to the upper edge of the side member (5) over the side sill (4), and the door (6) is connected to the side member (5). ) and the overhangs (1e) on each side were formed.

Since the upper space of b) can be secured even if the upper space is relatively sandwiched, the single chamber (1b) is provided with overhangs (1e) (1e) on both sides of the lower part.
In contrast to e), the cross section is formed into a substantially triangular shape with the upper part sandwiched in between,
The vehicle body (1) extends from the front of the vehicle body (1), which has a substantially triangular cross section with the central engine room (1a) and the front fenders (IC) (14,0) on both sides, to the vehicle compartment (1b).
The shape of the cross-section m1 of 1 is made to change continuously, making it possible to further reduce aerodynamic drag.
