<p>PURPOSE:To secure a feeling of smooth steering without entailing any yawing in time of high speed driving, by making rear wheels turn and steer in the opposite phase to front wheels at a time when a turn-steering angle of each front wheel goes beyond the specified value. CONSTITUTION:When a car is turned round clockwise, a rotary shaft 34 is also turned round clockwise via a same turn-steering controlling force transmission device when a turn-steering angle thetaH is smaller than the specified value theta2, and a shaft member 32 moves to the left whereby each rear wheel 30 is steered to turn round clockwise. These rear wheels 30 are steered to turn round in the same direction as far as a portion for an angle proportionate to the turn-steering angle thetaH of front wheels 10. At this time, transmission of rotation in reverse direction-steering controlling force is shut off by a dead zone setting device so that a reverse direction turn-steering controlling force transmission device will no longer be operated. When the turn-steering angle thetaH of each front wheel 10 is larger than the specified value theta2, both the same direction turn-steering controlling force transmission device and the reverse direction turn-steering controlling force transmission device try to operate but the rotary shaft 34 is rotated in the reverse direction against a rotary shaft 20 by a reversible direction transmission device.</p> |
