Abstract

A hydraulic steering system (1) for a vehicle with two steering motor arrangements, particularly an articulated vehicle with wheel steering, with a hydraulic steering unit (2) having a measuring motor section (22, 23), with a selection valve (6), which connects an outlet (L, R) of the steering unit (2) with either a first steering motor arrangement (7) that preferably acts upon steered wheels, or a second steering motor arrangement (9) that preferably acts upon a converting kit, and which is hydraulically operable via a pilot valve (14), and with a pump (4), which is connected with the steering unit (2) and the pilot valve (14). This permits the vehicle to be steerable in connection with an emergency.
