1. A motor-vehicle wheel suspension, comprising a wheel support connected to a motor-vehicle supporting structure by at least the following connecting elements:
a lower oscillating arm, having an inner end pivotally connected to said supporting structure around a first articulation axis and an outer end pivotally connected to the wheel support around a second articulation axis, a damper unit having a lower end pivotally connected to the lower oscillating arm around a third articulation axis, and an upper end connected in an articulated manner to a motor-vehicle structure, an upper oscillating rod for camber control, having opposite ends articulated to the supporting structure and the wheel support respectively around fourth and fifth articulation axes, a vertical articulated rod having an upper end pivotally connected to the wheel support around a sixth articulation axis and a lower end pivotally connected to the outer end of the lower oscillating arm, an oscillating toe rod for toe control which has an inner end pivotally connected to said supporting structure around a seventh articulation axis and an outer end which is pivotally connected to the wheel support, the lower end of the vertical rod pivotally connected to the outer end of the lower oscillating arm around said third articulation axis, around which the lower end of the damper unit is also articulated, the outer end of said toe rod is pivotally connected to the wheel support around said sixth articulation axis, around which the upper end of said vertical rod is also articulated, the articulation of the outer end of said toe rod to the wheel support and to the upper end of said vertical rod comprises:
an articulation axle rigidly connected to said upper end of the vertical rod and projecting axially in cantilever fashion therefrom,a cylindrical cavity formed in the outer end of said toe rod which rotatably receives therein said articulation axle, for articulation of said toe rod around said articulation axle,an eccentric cylindrical member rigidly connected to said articulation axle and rotatably mounted within a cylindrical cavity formed in said wheel support and having an axis which is eccentric with respect to said articulation axle, andan adjustment ring rigidly connected to said articulation axle, in such a way that an angular adjustment of said ring determines a change of position of the wheel support which causes a variation of a toe angle of the wheel, without modifying the position of said seventh articulation axis of the toe rod to the supporting structure and without modifying the distance between said sixth and seventh axes around which the opposite ends of said toe rod are articulated. |
