Abstract

L’invention concerne un dispositif pour frein à tambour (1) pour véhicule routier. Le dispositif comprend un actionneur (2) configuré pour solliciter en écartement deux segments (12, 13) vers un tambour de frein. L’actionneur (2) comprend un élément élastique de sollicitation (35) qui est configuré pour être déformé élastiquement lorsque le frein (1) est dans une première position de freinage, et pour solliciter le frein (1) vers une deuxième position de freinage lorsque l’actionneur (2) a été actionné et que le frein (1) cesse d’être dans la première position de freinage. L’élément élastique de sollicitation (35) a une raideur comprise strictement entre 0 et 500 N/m. Figure pour l’abrégé : figure 7
