Abstract
An electromechanical multiple-disk brake actuator is provided. The actuator includes a first reversible assembly with a central screw, a first electric motor rotating the screw, a first nut displaceable over the screw when the screw is rotated and a connection between the screw and the nut permit reversible displacement. The actuator also has a second non-reversible assembly including an annular screw on the first nut, a second electric motor for rotating the annular screw and the first nut, and a second nut fixed to a frame but axially displaceable over the annual screw when the annular screw is rotated. A piston at one of the ends of the second nut presses the disk against one another to ensure braking.
