Corrected variable reduction direction, characterized in that the steering axis drives a worm, whose rotation determines the axial displacement of a threaded nut, which is articulated by a point of its periphery, to a rigid and inextensible lever, also articulated, on the other hand, to a fixed point, which, in turn, forces to describe a circular movement to the point of the periphery of the nut, equivalent to a rotation of the latter, a movement that, being composed of the rectilinear caused by the rotation of the screw determines a sinusoidal trajectory for the point of the periphery of the nut, a point that materializes in a rod, normally emerging from the nut, which is coupled to a ball joint arrangement integral with the lever.
