Abstract

L'invention concerne un ensemble de traction (10) dont la capacité de fermeture et la résistance à la fermeture sont améliorées grâce à la création d'une surface inférieure inclinée (62) sur les plaques tronconiques (56) situées au milieu des surfaces de frottement interne et externe dans la zone où la plaque à dépouille (56) est en contact avec la troisième nervure horizontale (24) du boîtier (12). La création d'un angle sur la surface inférieure latérale des plaques tronconiques (56) dans cette zone permet d'augmenter la force latérale sur les plaques mobiles pendant l'application d'un choc de polissage sur l'ensemble de traction (10).
