Aerodynamic component for automobiles
An aerodynamic component disposed on a side face of an upper rear part of an automobile vehicle body and reduces a lift coefficient of a vehicle body rear part, includes a plate-shaped base part and a fin projectingly provided on a front face of the base part, wherein the base part gently increases in thickness from a front edge side to a rear edge side, and has at the rear edge a shape that rises steeply with respect to the side face of the upper rear part of the vehicle body.
1. An aerodynamic component for automobiles, the aerodynamic component, which is disposed on a side face of an upper rear part of an automobile vehicle body and reduces a lift coefficient (CLr) of a vehicle body rear part, comprising a plate-shaped base part and a fin projectingly provided on a front face of the base part, wherein the base part gently increases in thickness from a front edge side to a rear edge side, and has at the rear edge a shape that rises steeply with respect to the side face of the upper rear part of the vehicle body.
2. The aerodynamic component for automobiles according to claim 1 , wherein the aerodynamic component is disposed on a surface of a rear pillar of the automobile, and the rear edge of the base part, which is formed into a linear shape, is inclined from lower front to upper rear or from upper front to lower rear.
3. The aerodynamic component for automobiles according to claim 1 , wherein the fin comprises a plurality of first fins extending in a fore-and-aft direction, and the plurality of first fins are arranged side by side in an up-and-down direction so as to be parallel to each other.
4. The aerodynamic component for automobiles according to claim 3 , wherein the fin comprises a single second fin extending in the fore-and-aft direction, the second fin is disposed along an upper edge of the base part, and a length of the second fin in the fore-and-aft direction is larger than a length of the first fin in the fore-and-aft direction.
5. The aerodynamic component for automobiles according to claim 1 , wherein the front face and a reverse face of the base part form an angle of about 20° at the front edge.
6. The aerodynamic component for automobiles according to claim 1 , wherein the lift coefficient (CLr) of the vehicle body rear part that has been reduced by the aerodynamic component substantially coincides with a lift coefficient (CLf) of a vehicle body front part.
7. The aerodynamic component for automobiles according to claim 1 , wherein the aerodynamic component is detachably fixed to the vehicle body.
8. The aerodynamic component for automobiles according to claim 1 , wherein the aerodynamic component is formed integrally with the vehicle body.
