<p>PURPOSE:To steer rear wheels with a complicated steering-angle function which constituted of the sum of a plurality of functions by pivotally supporting an arm member at two points by means of a connecting rod and an eccentric pin. CONSTITUTION:An arm member 41 whose intermediate part is pivotally supported by a pivotal supporting pin 38 at the right edge of a connecting rod 37 whose left edge is pivotally supported by an eccentric pin 34 on a drive gear 33 swings vertically through the transverse movement of the tie rods 13 and 13 at right and left which are connected and supported by the lower edge of the arm member 41, so that rear wheels are steered as shown by a curve A in sinusoidal wave form, having an upper part pivotal supporting point 36 as an immovable supporting point. While, the arm member 41 whose upper part is pivotally supported by the eccentric pin 36 on a driven gear 35 swings vertically so as to steer rear wheels as shown by a curve B in parabola form, having a lower part pivotally supporting point 38 as an immovable supporting point. Therefore, rear wheels are steered with a steering-angle function as shown by a complicated curve C newly synthesized from the curves A and B.</p> |
