Abstract

L'invention concerne un treuil de faible épaisseur pour un ascenseur. L'objectif de l'invention est d'une part de réduire l'épaisseur et le poids de ce treuil par une réduction des composants de ce dernier pour permettre de diminuer l'épaisseur latérale dudit treuil, et d'autre part d'accroître le degré de liberté sur le site d'installation et de réduire la surface de la cage vue de dessus. Ce treuil présente un corps de base (202), un arbre principal (217) monté dans le corps de base, un corps rotatif (219) monté de manière à pouvoir pivoter sur l'arbre principal, une poulie d'entraînement (220) formée dans le corps rotatif, un stator (218) monté dans le corps de base, un induit (221) disposé sur la périphérie extérieure du corps rotatif face au stator de façon à former un moteur en association avec stator, une surface de freinage (291) formée sur le corps rotatif, présentant un diamètre supérieur à celui de la dimension extérieure de la poulie d'entraînement, et un frein (222) disposé face à la surface de freinage et comprimé par cette dernière lors du freinage. Une surface de fond de corps de base (204), raccordée à une partie de support de palier (205) supportant l'arbre principal du corps rotatif, et la poulie d'entraînement sont disposées à proximité l'une de l'autre de sorte que l'arbre principal du corps rotatif puisse être placé en porte-à-faux sur la partie de support de palier du corps de base.
