Abstract

L'invention concerne un mécanisme de freinage d'un arbre de moteur. Ce mécanisme comprend un levier qui pivote par une extrémité et dont l'autre extrémité est soumise à la force d'un organe élastique de serrage et, le cas échéant, d'un dispositif magnétique de desserrage. Un organe d'appui, proche de l'extrémité de pivotement du levier, est destiné à porter contre une semelle de frein afin que cette dernière entre en contact avec un disque solidaire de l'arbre à freiner. La démultiplication ainsi obtenue au serrage et au desserrage est importante. Domaine d'application : freins d'arbres de moteurs électriques, etc.
