57	Abstract	AB	Die Erfindung betrifft eine Vorrichtung zur Lenkkraftunterstützung eines Kraftfahrzeuges, insbesondere eines Nutzfahrzeuges, mit zumindest zwei Achsen, von denen zumindest eine Achse über eine Servolenkung gelenkt ist und die Räder des Kraftfahrzeuges über eine Betriebsbremse bremsbar sind, wobei zur Erzeugung einer Lenkkraftunterstützung bei Ausfall der Servolenkung die Radaufhängung der lenkbaren Räder durch entsprechende Auslegung der Radführungselemente, des Spreizungswinkels der Lenkachse und des Radsturzwinkels einen positiven Lenkrollradius aufweist und das jeweil kurveninnere Rad abhängig vom Lenkwinkel und/oder dem aufgebrachten Lenkmoment gebremst wird. Zur Erzielung einer noch wirkungsvolleren Lenkkraftunterstützung wird vorgeschlagen, dass der Spreizungswinkel (γ) derart ausgeführt ist, dass die Lenkachse (14) in Fahrzeughochachsenrichtung, von unten nach oben gesehen, nach innen zur Fahrzeugmitte hingeneigt ist.
