    摘要: 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.

    摘要: A steering system (1) for a vehicle with a first steering arrangement (6), with a first sensor (7), with a second steering arrangement (8), which includes an articulated steering, which has a second sensor (9), and with a steering unit (5). To improve the steering comfort, the steering unit (5) is fixedly connected with the first steering arrangement (6) and the second steering arrangement (8) is connected with a follow-up arrangement, which comprises the first sensor (7), a control device (10) and a valve arrangement (11).
