Abstract

PURPOSE:To reduce the influence of cross wind against stability of the rectilinear motion of a vehicle so as to enhance stability in controlling the vehicle by extending fins continuously in the longitudinal direction of the vehicle along the boundary portion of the side face and upper face of the vehicle body, and making the contour of the cross section of the body near a connecting portion recessed outwards. CONSTITUTION:A vehicle body is provided with fins 6 and an air flow from a rear fender 5 toward a rear deck 2 is blocked by the fins 6 and dynamic pressure is applied to the vehicle body accordingly. The windward face of the fender 5 therefore tends to be exerted with positive pressure and at the same time an air flow passing over the edge of each fin 6 is separated from the fins 6 and swirls on the lee. Thereby the lee side of each fin 6 tends to be exerted with negative pressure and the rear portion of the vehicle body is pushed to the lee by the swirl end also by the dynamic pressure. Yawing moment caused by cross wind is therefore canceled out and a yawing moment coefficient is decreased. Also the connecting portion 5a of the rear fender 5 to each fin 6 is formed into a concave of a relatively large curvature and thereby the air flow along the rear fender 5 collides with the outside face of each fin 6 at almost right angles thereto and the effect of dynamic pressure is further enhanced.

<Prior Art> When a vehicle encounters a crosswind, a vehicle traveling straight travels while receiving an airflow that is a combination of the airflow from the front and the airflow from the side, that is, the airflow from diagonally ahead. In such a state, a pressure difference occurs on both sides of the vehicle body, and a lateral component (side force: S) is generated in the aerodynamic force acting on the vehicle body.

A yaw moment (My), expressed as the product (Sl) of the lateral component of the aerodynamic force (S) and the distance (Ω) between the aerodynamic center A and the center of gravity G, acts on the vehicle body, and the yaw angle (ψ ) It is known that a vehicle exhibits a behavior in which it turns to the leeward side by an angle shown by . In particular, vehicles with midship engines tend to have their center of gravity relatively located at the rear of the vehicle.
The effect of the crosswind described above tends to be even more pronounced.

In addition, as the weight of vehicles is reduced, the tire corner link power (cornering force per unit slip angle) decreases, so a larger slip angle is required to generate cornering force that can counter side forces. It becomes necessary. Furthermore, when the yaw moment of inertia is reduced due to weight reduction, the inertial resistance to rotational movement becomes smaller. For these reasons, there is a tendency for crosswind stability to deteriorate due to weight reduction.

<Problems to be Solved by the Invention> Incidentally, it is known that fins are provided on the rear sides of the vehicle body as a means to avoid deterioration of steering stability due to crosswinds, but it is difficult to actually verify the effect. If you try to achieve this, other problems tend to occur, such as an excessive area of the side surface of the vehicle body and an increase in the air resistance coefficient CD when driving straight.

The present invention was devised to eliminate these inconveniences, and its main purpose is to reduce the deterioration of steering stability when the vehicle is hit by a crosswind, without increasing the drag force when driving straight. An object of the present invention is to provide a vehicle body rear structure including an aerodynamic member that can be suppressed.

[Structure of the Invention] Means for Solving the Problems According to the present invention, fins are provided on each of the left and right sides of the vehicle body so that the upper edges thereof face diagonally outward. A vehicle rear body structure for a vehicle having:
It extends continuously in the longitudinal direction of the vehicle body along the airflow when traveling straight at the boundary between the side surface of the vehicle body and the top surface of the vehicle body from the roof end to the rear deck end. The cross-sectional profile near the connection part is
This is achieved by providing a vehicle rear body structure that is characterized by an outwardly concave shape.

<Function> In this way, by configuring the fins so that the longitudinal direction of the fins is aligned with the axis of the airflow in the longitudinal direction of the vehicle, it is possible to suppress an increase in the drag force against the airflow directly facing the vehicle.

In addition, when a crosswind is encountered, the fins block the airflow flowing from the rear fender to the rear deck, and the fins receive the dynamic pressure of the airflow with high efficiency. Pressure decreases. This creates a rotational moment that tends to direct the rear of the vehicle downwind, which offsets the yawing moment caused by the crosswind.

従って、車輌の直進性を好適に確保することかできる。Therefore, the straightness of the vehicle can be suitably ensured.

FIG. 1 is an overall view of a vehicle to which the present invention is applied, viewed diagonally from the rear. This vehicle has a so-called notchback configuration in which the upper surface of a rear window 1 and the upper surface of a rear deck 2 covered by a trunk lid are bent. Then, as shown in FIG. 2, the end starts at the rear end of the roof 3,
A fin 6 is erected on the ridge line of the part where the rear deck 2 and both left and right rear fenders 5 connect, extending through the rear quarter pillar 4 to the rear end of the rear deck 2, along the airflow when traveling straight.

After considering the ridgeline on the side of the car body, we found that when installing fins in such a way that the air resistance coefficient CD does not increase when the fin 6 is installed, it is necessary to install the fins at approximately the center of the rear part of the car body or slightly outwards, as shown in Figure 2. I set the ridgeline in the shape of a narrowed shape at the rear. By setting such a ridgeline to follow the airflow when traveling straight, when the fin 6 is attached to the ridgeline, the difference in air flow lines around the rear of the vehicle when traveling straight and when encountering a crosswind can be skillfully utilized. As a result, the yaw moment coefficient C9,1 when a crosswind is encountered can be effectively reduced without increasing the air resistance coefficient CD when traveling straight.

These fins 6 are raised obliquely outward at an angle of about 45 degrees with respect to the horizontal plane. The connecting portion 5a of the rear fender 5 with the fin 6 is continuous with the outer surface of the fin 6 with a concave surface having a relatively large curvature. Further, the upper edge of the fin 6 has a relatively sharp knife edge.

The basic cross-sectional contour of the rear part of the vehicle body, which is composed of the rear deck 2 and the rear fender 5, is approximately trapezoidal with a widened base. Furthermore, the rear end 7 is cut off substantially vertically, and its ridge line 7a is relatively sharply angled.

Now, the value obtained by making the above-mentioned yaw ink moment My dimensionless using the air flow dynamic pressure (1/2 ρV2), the front projected area A1, and the wheel base WB is called the yawing moment coefficient CY, and this value is It is well known that lowering the height contributes to improving straight-line stability against crosswinds.

By the way, in the case of a car body without fins at the rear, when a crosswind is encountered, as shown in Figure 3, high-velocity air flows around from the fender 5' to the rear deck 2', so the fender surface on the windward side tends to have negative pressure. becomes.

This is a cause of increasing the yawing moment coefficient CYM. On the other hand, when fins are provided on the vehicle body, the airflow from the rear fender 5 toward the rear deck 2 is blocked by the fins 6, as shown by the arrow shown in FIG.
The fins 6 receive dynamic pressure.

Therefore, the windward side surface of the fender 5 tends to have positive pressure. At the same time, the airflow that went over the edge of fin 6,
It separates from the fin 6 and generates a vortex on the leeward side of the fin 6.

As a result, the leeward side of the fins 6 tends to have a negative pressure. This negative pressure, together with the above-mentioned dynamic pressure, has the effect of pushing the rear portion of the vehicle body toward the leeward side. Therefore, the yawing moment MY due to the crosswind is canceled out, and the yawing moment coefficient CYM is reduced.

Furthermore, by making the connecting portion 5a of the rear fender 5 with the fin 6 a concave surface with a relatively large curvature, the airflow along the rear fender 5 collides with the outer surface of the fin 6 at an angle close to a right angle. The dynamic pressure effect is further enhanced.

Furthermore, by cutting off the rear end 7 vertically and clearly squaring the ridgeline 7a between it and the rear fender 5, the airflow along the rear end 7 is separated, further increasing the negative pressure tendency on the leeward side.

Here, as a result of comparing the experimental values of air resistance coefficient C111% lift coefficient C1 and yawing moment coefficient CYM determined according to the presence or absence of fins using a 1/5 scale model, it was found that considering the yawing moment coefficient Cy against cross wind By providing fins, the CYM value decreases uniformly compared to one without fins, but even when divided, the fin angle of 45 degrees is the most effective, and the longer the overall length, the greater the effect. Served. Furthermore, it has been found that by aligning the longitudinal direction of the fins 6 with the airflow when traveling straight, it is possible to suppress an increase in the CD value due to the provision of the fins 6. Furthermore, if the fins were in an appropriate range, they were effective in reducing the lift coefficient Ct (in the direction of grip force) when a crosswind was encountered.

In reality, the side force S acting near the center of gravity of the vehicle body will not contribute to canceling out the yaw moment MY, and considering the balance with the CD value and C1 value, the fin will extend from the roof end to the rear deck end. It is thought that providing the following will produce the best results.
