VEHICLE AERODYNAMIC CHARACTERISTIC OPTIMIZATION DEVICE USING MOVABLE PLATE-SHAPED ARCH MEMBER

摘要

PROBLEM TO BE SOLVED: To install means for optimizing an aerodynamic characteristic such as a yaw resistance characteristic and a roll resistance characteristic against a crosswind blown to a vehicle at a front end part of a vehicle without impairing the external appearance of the vehicle while taking into consideration that the front end part of the vehicle is the most sensitive with respect to the yaw moment and the roll moment by eliminating a risk that, when the vehicle receives the cross wind during traveling, the vehicle may cause a yaw change and rolling by receiving the yaw moment and the roll moment.;SOLUTION: There is provided a plate-shaped arch member which is movable between a position in which the member is accommodated in a wheel arch along a peripheral wall of the wheel arch, and a position in which a part of the member is protruded to the outside of the wheel arch.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
