ABSTRACT:
A steering gear of the type comprising a pulley rotatable by means of a steering wheel, and a member to be steered by wire ropes extending from the pulley, is arranged to provide a restoring moment. The rotatable pulley is formed with two adjoining grooves having a width corresponding to the cross-sectional dimension of the respective wire ropes, and a depth permitting at least two turns of wire rope to be wound thereinto. The restoring moment is obtained in that when steering movements are effected the run of the wire rope being wound onto the pulley and extending tangentially thereof will be situated at an effective radial distance from the center of the pulley greater than that of the corresponding run of the wire rope being unwound from the pulley.
