Abstract: Tilting devices suitable to vehicles that are free to tilt and free to be steered, apt to let them lean when driving and to keep them standing when stopped only by means of their brakes (or the like) (61, 62), characterized in that, due to a suitable tilt axis inclination with reference to the ground and to a proper combination and proportion of parts, any lateral rotation of the tilting vehicle around its tilt axis (at) is kinematically linked to a differential longitudinal displacement (fdd) of at least two wheels (wh1, wh2) (or endless tracks, snow skis, ice skates, or the like), in a way that the tilting vehicle can effectively be kept standing when stopped and can be parked perpendicular to the ground and crosswise a slope of at least 15% by simply operating the vehicle's brakes (or the like) (61, 62) and without further locking devices.
