<p>PURPOSE:To improve operation performance by freely fitting a joint member with which a rear-wheel tie-rod is connected onto an oscillating member driven by a motor and allowing the steering direction of rear wheels to be varied according to car speed, in an apparatus for steering rear wheels, interlocked with the steering of front wheels. CONSTITUTION:At the same time when front wheels are steered by the operation of a steering wheel, rear wheels 22 are steered through an operating shaft 9. In such a sterring apparatus, an oscillating shaft 14 is connected at the rear edge of the operating shaft 9 through a universal joint 11, input shaft 12, and a universal joint 15. A joint member 16 with which the inner edge parts of a rear-wheel steering tie-rod 25 are connected on both edge parts is freely fitted in the intermediate part of the oscillating shaft 14, and the center part of an arm member 17 which exteends in the direction of car width is fixed onto the member 16. The right edge of the arm member 17 is conected to the chassis side through a link 18 and a bracket 19, and the left edge is connected to the chassis side through links 20 and 21 and a bracket 22. The worm gear 32a on an output shaft 32 for a motor 31 is engaged with a sector gear 24 fitted onto the pivotal shaft 23 of the link member 21.</p> |
