Abstract

L'invention concerne une courroie de transmission de force, en particulier une courroie trapézoïdale qui peut être dentée, une courroie trapézoïdale crantée ou une courroie synchrone, comprenant au moins un câble de traction d'un fil de base retordu en deux étapes et incorporé dans un corps de matériau élastique. Le fil de base non retordu est un fil multifilament qui contient une pluralité de filaments d'aramide. Il est tordu dans une première étape de torsion en une torsade avant et dans une deuxième étape de torsion dans le sens opposé à la première étape de torsion en une torsade extérieure pour former le câble de traction. Le fil de base, selon l'invention, présente un titre inférieur à 1000 dtex. Dans l'étape de torsion, deux ou trois fils du fil de base sont tordus à torsade avant et dans la deuxième étape de torsion, trois à six fils sont tordus à la torsade extérieure. Le rapport entre le facteur de torsion de la torsade avant (F1) et le facteur de torsion de la torsade extérieure (F2) est de 0,8 à moins de 1 et le rapport entre la torsion (D1 [m-1]) de la torsade avant et la torsion (D2 [m-1]) de la torsade extérieure est de 1 à 1,5. La résistance à la traction, en particulier pour la courroie pour moteurs RSG, peut être augmentée de manière significative à travers la construction du câble de traction spécial.
