<p>PURPOSE:To aim at miniaturization and simplification in structure and improvement in functional reliability and so on by rotating a pair of long and short arms installed in a pair of shafts with the steering of front wheels, and tilting a link connected to these arms to the longitudinal direction of a vehicle, then steering rear wheels. CONSTITUTION:When a steering wheel 2 is turned to the right, by way of example, a tie rod 8 is moved to the left, and a knuckle arm 6 is rotated clockwise around a fulcrum shaft 6a, so that front wheels 4 are steered to the right. At this time, an input shaft 10 is rotated, and a long arm 51 is rotated clockwise together with a shaft 42 via each of bevel gears 41, 46 in a steering angle control mechanism 12. Simultaneously, a short arm 48 of a shaft 45 is rotated counterclockwise via each of bevel gears 49, 46. When the long arm 51 is rotated as much as a specified angle (less than 90 degrees), by way of example, the short arm 48 is rotated as long as 90 degrees clockwise, whereby a pin 14 at the end of a link 50 is moved to the right ahead. In consequence, a tie rod 23 is moved to the right, and rear wheels 27 are steered in a maximum steering state in the same phase.</p> |
