Abstract

Die Erfindung betrifft eine hydraulische Servolenkung für Kraftfahrzeuge mit DOLLAR A einem hydraulischen Servomotor, DOLLAR A einem Drehschieberventil mit Steuernuten und Steuerkanten DOLLAR A sowie mit DOLLAR A einer Servopumpe, die dazu eingerichtet ist, im Betrieb wenigstens zwei verschiedene Volumenströme eines Hydraulikfluids zur Verfügung zu stellen. DOLLAR A Eine Parametrisierbarkeit wird dadurch erreicht, dass die Steuerkanten eine Innenfase und eine Außenfase unterschiedlicher Neigung aufweisen.The invention relates to a hydraulic power steering for motor vehicles with DOLLAR A a hydraulic servomotor, DOLLAR A a rotary valve with control grooves and control edges DOLLAR A and DOLLAR A of a servo pump, which is adapted to provide at least two different volume flows of a hydraulic fluid during operation. DOLLAR A Parametrisierbarkeit is achieved in that the control edges have a Innenfase and an outer bevel of different inclination.
