Hydraulische Lenkeinrichtung mit Übersetzungsänderung

摘要

The invention relates to a steering device that is provided with one or more dosage pumps (7, 7') and with a switch element (17) interposed between two adjacent dosage pumps (7, 7'). The switching element switches between the power-assisted steering mode, in which the feed volumes of the pumps add up, and the emergency steering mode, in which only the first dosing pump (8) feeds the hydraulic fluid.
