Abstract

La présente invention concerne un actionneur (10) pour un système de verrouillage en stationnement d’une boîte de transmission de véhicule, ledit actionneur (10) comprend un moteur électrique (1) ayant une carcasse (2) dans laquelle sont logés un stator (3) et un rotor (4), ledit rotor (4) étant lié à un arbre rotatif (5), ledit arbre (5) étant guidé en rotation par au moins deux éléments de guidage (6, 7), ledit actionneur (10) comprend en outre un mécanisme avec une roue (21) et une vis sans fin (20) située sur l’arbre moteur (5). Au moins deux bagues (8, 9) sont montées sur l’arbre moteur (5) de manière à ce que sous l’effet d’un effort axial (F1, F2) généré par la roue (21) sur la vis sans fin (20) au moins l’une des bagues (8, 9) vient en butée contre la carcasse (2) ou contre au moins un des éléments de guidage (6, 7) afin de générer un couple de frottement rendant ainsi l’actionneur (10) en situation d’arc-boutement.
