<p>Device applied to the tread of one or more wheels of a vehicle to induce an oscillatory movement to the vehicle itself, comprising a concave internal profile (2) having a constant curvature in the plane of the wheel for receiving the wheel itself and an external profile (1) of substantially convex shape and of variable curvature in the plane of the wheel, so that by turning said wheel in contact with the ground, the axis of the wheel to which the device is applied swings vertically causing the said oscillatory movement.</p> |
