iiier beschriebene "Luftströmung" ähnelt dem bewährten Virkungsprinsip einer luftdurchlässigen Landeklappe eines modernen Flugzeuges. Auch bei der Ausführung eines modernen Heekeppilers an PKVs, Sport- und Rennwagen sorgt die durch Luftsohlita wirkende Luftströmung tür höheren Aehsdruok.The "air flow" described is similar to the proven principle of operation of an air-permeable landing flap on a modern aircraft. Even in the case of a modern landing flap on a passenger car, sports car and racing car, the air flow acting through the air flap ensures higher air pressure.

Die S-förmige Sobaufelausftthrung (FIG.3) sorgt tür eine teil« weise Umlenkung des Luftdruckes auf die Sehaufeücaden, wodurch bei Ausnutzung de· längeren Hebelarme· mit stärkerer Snergieausnutsung zu rechnen ist.The S-shaped suspension design (FIG.3) ensures a partial redirection of the air pressure to the suspension surfaces, whereby greater energy utilization can be expected when the longer lever arms are used.
