Abstract

La présente invention se rapport au domaine du génie mécanique et concerne des systèmes de freinage pour des foreuses minières. L'invention consiste essentiellement en un disque de frottement rotatif (7) disposé entre un élément de pression (11) et en un disque de frottement non rotatif (6) de manière à pouvoir effectuer un mouvement longitudinal par rapport à l'axe longitudinal (X) d'un arbre (5). L'élément de pression (11) se présente sous forme d'un disque de frottement non rotatif qui entre en interaction avec un élément ressort (12) relié cinématiquement à un actionneur de l'élément de pression (11), tandis que le disque de frottement non rotatif (6) est immobile par rapport à l'arbre (5) et est fixé entre le corps (13) et la base (4). Le résultat technique consiste en une diminution des paramètres dimensionnels et une augmentation de la fiabilité d'exploitation du système de freinage.
