Abstract

L’actionneur (1) électrique pour frein de véhicule automobile comprend :- un moteur électrique (6) muni d’un arbre rotatif, et - un dispositif (7) vis-écrou destiné à déplacer, sous l’effet de l’arbre rotatif du moteur électrique, des moyens mécaniques (4) de serrage du frein de manière à augmenter ou diminuer une force de serrage du frein. L’écrou (11) du dispositif vis-écrou est mobile en translation le long d’un axe longitudinal (A) de la vis (10) et est immobile en rotation. L’actionneur (1) comprend en outre des moyens de transmission du mouvement de translation de l’écrou aux moyens mécaniques (4) de serrage du frein de manière à augmenter ou diminuer une force de serrage du frein.
