Device for improving driveability of a road vehicle and road vehicle using such a device

摘要

The device, which may be used singly or multiply in road vehicles, for improving the driving characteristics includes at least one freely rotatable guide fin, whose first pivotal axis is connected to the vehicle structure, and, above the guide fin, an upwardly projecting control fin, which is pivotable about a second pivotal axis and which adjusts the guide fin by means of air force in order to achieve predetermined guide forces in dependence on its deflection, with respect to the guide fin.
