<p>PURPOSE:To carry out the turn steering of rear wheels with good response by means of optimum power by increasing or decreasing the steering gain in response to the steering speed of a steering wheel. CONSTITUTION:Rear wheel steering judging mechanism 1 judges the speed of rotary displacement of an input shaft 25, namely, the speed of steering of a steering wheel 1, and decides the direction and the magnitude of steering angle of the rear wheels 18 in response to the judged result and the rotary displacement of the input shaft 25, namely, the steering angle of the steering wheel 1 to generate the linear displacement in a linkage 14. At this time, the steering force which is necessary to generate the linear displacement of the linkage 14 is relieved by means of oil pressure generated by a vane pump 61. the linear displacement of the linkage 14 causes a knuckle arm 16 to rotate about a pivot axis 17 through a tie rod 15. Together with this rotation, the rear wheels 18 are made the turn steering to generate the steering in the rear wheels 18.</p> |
