Abstract

L'invention a pour objet un système de freinage et de non-retour. Pour le freinage, la pièce à freiner 1 est serrée par des pyramides de galets 2-3, à l'aide de deux liens 4, qui s'enroulent sur un tambour 5, commandé par levier 6 de serrage et de freinage. Pour le non-retour, les pyramides de galets, le tambour 5 et son levier 6 placés sur une couronne à joues 7 axée sur l'axe de la poulie à freiner, sont orientés vers des plans rectilignes 9 et 9' fixes, ceci suivant le sens du mouvement qui àssurent le blocage.
