Abstract

Nella leva di comando di un freno a ceppi a espansione è girevole una ruota elicoidale calettabile sull'asse di comando di un bocciolo d'azionamento di un freno a ceppi. La ruota elicoidale (12) è vincolata angolarmente dall'impegno con una vite perpetua (16). Un rocchetto (40) coassiale alla vite perpetua è in collegamento unidirezionale con essa tramite un meccanismo a ruota libera (36, 38, 42, 44) ed è mosso avanti e indietro da una cremagliera (54) comandata da un nottolino solidale al supporto del freno per provocare una rotazione corrispondente della vite perpetua (16) quando lo spostamento della leva di comando supera un'entità prestabilita. Secondo l'invenzione, la rotazione della vite perpetua (16) provoca successivi spostamenti incrementali di un riscontro (20) di detto meccanismo a ruota libera fino ad una posizione finale di svincolo.
