Abstract
Linear electromechanical actuator (), comprising a containment structure (); a pusher (); a mechanical reduction apparatus (); drive means () operatively connected to said mechanical reduction apparatus () to rotate it about said rotation axis (X); a shaft () connected to said mechanical reduction apparatus () such that a rotation of said mechanical reduction apparatus () determines a translation of the shaft () along said rotation axis (X); an active anti-rotation mechanism; the mechanical reduction apparatus () comprises a nut () and a longitudinal pushing element independent of each other and rotatable about said rotation axis (X) under the action of said drive means (); said longitudinal pushing element () being fitted into said nut (); coupling means () configured to mechanically couple said nut () and said longitudinal pushing element () with said shaft (), such that a rotation of said nut () and/or of said longitudinal pushing element () determines a translation of said shaft () along said rotation axis (X); said coupling means () comprising: an intermediate coupling stage () interposed between the nut () and the longitudinal pushing element (), said shaft () being at least partially fitted into said intermediate coupling stage and into said longitudinal pushing element ().
