Abstract

CE FREIN A TAMBOUR COMPREND DEUX SEGMENTS 14 ET 16 ACTIONNES PAR DEUX DISPOSITIFS 22 DIAMETRALEMENT OPPOSES. CHAQUE DISPOSITIF DE COMMANDE COMPREND UN CORPS 30 DANS LEQUEL COULISSENT DEUX PISTONS 32, 34, BLOQUES EN ROTATION, QUI SONT EUX-MEMES COMMANDES PAR UN VERIN AGISSANT PAR UN POUSSOIR A GALETS 42, 44 SUR LEURS FACES INCLINEES. LE PISTON 32 RENFERME UN DISPOSITIF DE RATTRAPAGE DE JEU COMPORTANT UNE VIS 60 BLOQUEE EN ROTATION SUR LE SEGMENT 14 ET UN ECROU 62 BLOQUE EN TRANSLATION DANS LE PISTON ET ENTRAINE EN ROTATION PAR UN MANCHON 68 PAR L'INTERMEDIAIRE D'UNE ROUE LIBRE A ROULEAUX 70. LE MANCHON 68 PRESENTE UNE RAINURE HELICOIDALE 74 DANS LAQUELLE EST ENGAGE UN ERGOT 76 QUI EST SOLIDAIRE DU CORPS 30 ET DONT LE DIAMETRE EST INFERIEUR A LA LARGEUR DE LA RAINURE. LORSQUE, PAR SUITE D'UNE USURE EXCESSIVE DE LA GARNITURE, L'ERGOT RENCONTRE LE FLANC ARRIERE DE LA RAINURE 74, IL FAIT TOURNER LEGEREMENT LE MANCHON 68 POUR ENTRAINER L'ECROU 62 ET FAIRE AVANCER LE POUSSOIR 86 POUR RATTRAPER L'USURE.
