Abstract

L'invention concerne un dispositif d'entraînement (2) de porte pour le déplacement d'une porte (11) de véhicule par rapport à une carrosserie (10) de véhicule. Le dispositif comprend un élément de déplacement (21) destiné à provoquer un déplacement de la porte (11) de véhicule, une unité d'entraînement (22) électromotrice et une unité de sortie (26) qui peut être en liaison fonctionnelle avec l'unité d'entraînement (22) et qui est accouplée à l'élément de déplacement (21) pour l'application d'une force de déplacement dans l'élément de déplacement (21). Selon l'invention, l'unité de sortie (26) présente une broche (260) pouvant tourner autour d'un axe de rotation et un écrou (261) de broche en prise filetée avec la broche (260) et accouplé à l'élément de déplacement (21), une rotation de la broche (260) permettant le déplacement de l'écrou (261) de broche axialement le long de la broche (260) et ainsi la mobilité de l'élément de déplacement (21) pour le déplacement de la porte (11) de véhicule. De cette manière, un dispositif d'entraînement de porte est fourni, qui permet une construction simple, éventuellement avec modularité et adaptation flexibles, pour l'utilisation du dispositif d'entraînement de porte sur différentes portes de véhicule.
