PCT No. PCT/DE95/00246 Sec. 371 Date Sep. 3, 1996 Sec. 102(e) Date Sep. 3, 1996 PCT Filed Feb. 23, 1995 PCT Pub. No. WO95/23723 PCT Pub. Date Sep. 8, 1995The invention changes over to another steering ratio automatically and very safely on the transition from servo to emergency operation. In the steering system, only a few of the lines (13) link the metering pump (10) to one of the cylinder connections (7, 8) and in each of the other lines (13') there is a changeover unit (16) which also links the lines (13) to the cylinder connections (7, 8) or the delivery connection (6) depending on the method of operation. These steering systems are used in mobile systems, especially slow-moving vehicles. |
