A device for artificially restoring an opposing force for a device for remotely controlling an aircraft control surface, the device comprising: an actuator member () mounted to pivot about an axis () and entrain a rotary shaft (); a stationary finger () parallel to said shaft () and supported at a radial distance from the shaft; a moving finger () secured to the shaft and supported at the same radial distance as the stationary finger, both fingers being parallel to the shaft; a slab () supported at the same radial distance as the fingers and disposed beside them; a first spring () between the stationary finger and the slab; and a second spring () between the moving finger and the slab.

A device for remotely controlling the control surfaces of an aircraft, the device comprising: an actuator member pivotable about an axis and entraining a rotary shaft; a stationary finger parallel to the shaft and supported at a radial distance from the shaft; a moving finger secured to the shaft and supported at a radial distance therefrom, both fingers being parallel to the shaft; a first slab supported at a radial distance from the shaft beside the two fingers on one side thereof and suitable for turning about the axis of the shaft; a second slab supported at a radial distance from the shaft beside the two fingers on their side opposite from the first slab, and suitable for turning about the axis of the shaft; a third slab supported at a radial distance from the shaft beside the second slab at an angular distance therefrom and suitable for turning about the axis of the shaft; a first spring between the first and second slabs; and a second spring between the first and third slabs.

Device for remotely controlling aircraft control surfaces

The invention concerns an electromechanical actuator comprising at least an electric motor (), as well as coupling () and gear reduction () means, which drive an output shaft (). The invention is characterized in that the coupling and gear reduction means mesh with a crank plate () designed to be driven in rotation with an angular travel limited by two stops, a small connecting rod () being articulated to one end on a crank pin () of said crank plate and being articulated at its other end on a long connecting rod () which is itself integral with the output shaft, the two ends of said long connecting rod being respectively guided in displacement each along a guide, and the displacement angle between said two stops is more than 180&#xb0;, the movements of the rod being structurally locked in case of overriding, the crank plate being immediately proximate to one of its travel limit stops.
