  • Dual-circuit steer-by-wire steering system comprising a common cradle
    Patent number: 7331419
    Abstract: The invention relates to a steer-by-wire steering system comprising a hydraulic control unit that acts on the steerable wheels (1, 20), the control unit having at least one cradle (4, 23), which is displaceably mounted on at least one guide rod (5, 24) that passes through the respective cradle (4, 23). The respective cradle (4, 23) and the corresponding guide rod(s) (5, 24) form working chambers (A11, A12, A21, A22) of a piston-cylinder system, whereby each respective guide rod (5, 24) has at least one channel (KA11, KA12, KA21, KA22), each terminating in the vicinity of a working chamber (A11, A12, A21, A22). The cradle or cradles (4, 23) adjust the steerable wheels (1, 20) directly or by means of steering tie rods (2, 21).
