A hub for a motor vehicle wheel provides a cylindrical portion that extends in an axial direction, and a flange extending in a radially outer direction from an axially outer end of the cylindrical portion. The hub includes a core of metallic material which extends into the cylindrical portion and in the flange of the hub, and a covering body of plastic material applied over the core.

An electric screw actuator system, e.g. for an electrically driven and controlled steering device, comprises a screw actuator, an electric motor () engaging the screw actuator through a reduction gear mechanism (), electronic operating means for operating the screw actuator electrically, and a mechanical back-up system for operating the screw actuator in the absence of electric power e.g. in the case of an electric power failure of in the case the electric power is switched off, maintenance, garage parking etc. The mechanical back-up system comprises a manually controllable operation member () and an electromagnetic coupling (), said coupling disengaging the rotation member from the screw actuator in the case of nominal operation and availability of electric power, and engaging the rotation member with the screw actuator in the case of electric power failure.

A manual control device for electrically driven and controlled steering, and/or accelerating and/or decelerating of a road vehicle, that includes a hand grip device, sensors for sensing a force and/or a movement imposed on the hand grip device which correspond to a desired steering direction, and/or acceleration and/or deceleration of the vehicle, as well as a manual lever device comprising at least one mechanical connection for mechanically steering, and/or accelerating, and/or decelerating (e.g. maintenance parking etc.) of the vehicle in the absence of electric power (e.g. in the case of an electric power failure or in the case of electric power switched off) maintenance, garage parking etc., the manual lever device being swivelable or rotatable about at least one axis for actuating said at least one mechanical connection.
