<p>PURPOSE:To enable the steering angle ratio to be controlled in a simple manner by displacing a sliding body against a spring by means of the centrifugal force of a disc combined with and freely tilted to the shaft rotating according to vehicle speed and displacing the fulcrum shaft of a control lever so as to let the lever ratio be changeable. CONSTITUTION:A spherical body 41 is fixed onto a rotating shaft 42 equipped with a gear 44 meshed with the gear 46 of a propeller shaft 45 related to a differential device 47, and a spherical surface seat 40 formed into a disc 42 is rotatably coupled with the aforesaid spherical body 41 outwardly. A pair of rollers 38 engaging with each other in such a way as to hold the both surfaces of the aforesaid disc 42 is supported by shafts 38a onto a sliding frame 37 formed into a C figure configuration so that the sliding frame 37 is supported by a car body in such a way as to be slidable longitudinally while overcoming a pair of a front and a rear spring 35. The fulcrum shaft 19 is combined with a rod 34 projecting laterally from the sliding frame 37 so as to let the aforesaid shaft 29 be engaged with the longitudinal slot 33 of a braking lever 18 provided for a passage through which front wheel steering force is transmitted to a rear wheel steering mechanism. And the lever ratio of the braking lever 18 is changed depending on the longitidinal displacement of the sliding frame 37 so as to let the steering ratio be changed.</p> |
