摘要： A damper and spring unit includes a damper having a cylinder and a rod extending along a first axis (z), a spring plate arranged around the cylinder and slidable with respect to the cylinder along the first axis (z), a spring resting at its bottom on the spring plate, and an electro-mechanical adjustment device interposed between the cylinder and the spring plate for adjusting in a continuous and controlled manner the vertical position of the bottom end of the spring and the height of the vehicle from the ground. The adjustment device includes an electric motor generating a rotary motion and a motion conversion mechanism having one screw extending along a second axis (z′) parallel to the first axis (z), but spaced therefrom, and driven into rotation by the electric motor about the second axis (z′), and a nut meshing with the screw and drivingly connected for translation with the spring plate.

摘要： A vehicle is provided which has a vehicle body, at least one hub of a wheel, and a suspension connecting the hub to the vehicle body. The suspension has a suspension arm hinged to the vehicle body and to the hub, a spring, and an electromechanical rotary actuator operable between an active adjustment condition and a damping condition of the motion of the suspension, via a leverage.
