Abstract

CE SUPPORT, QUI COMPREND UN CORPS TUBULAIRE 10 FIXE A LA STRUCTURE PORTANTE 16, UN ORGANE D'ATTACHE 26 FIXE AU CORPS OSCILLANT ET RELIE CONCENTRIQUEMENT AU CORPS TUBULAIRE PAR UN ELEMENT ANNULAIRE 20 EN ELASTOMERE ET UN AMORTISSEUR A FRICTION DES OSCILLATIONS DE L'ORGANE D'ATTACHE RELATIVEMENT AU CORPS TUBULAIRE, EST CARACTERISE EN CE QUE L'ORGANE D'ATTACHE EST MUNI D'UNE JAMBE 34, QUI S'ETEND COAXIALEMENT DANS LE CORPS TUBULAIRE ET SUPPORTE UNE PAIRE DE PLAQUES TRANSVERSALES DE BUTEE 38, 40 DISTANTES AXIALEMENT L'UNE DE L'AUTRE ET EN CE QUE LE CORPS TUBULAIRE SUPPORTE UNE PLAQUE INTERMEDIAIRE 48 ENTRE LES DEUX PLAQUES DE BUTEE, PLAQUE DONT L'EPAISSEUR EST INFERIEURE A L'ECARTEMENT DES PLAQUES DE BUTEE ET QUI EST MUNIE D'UN TROU CENTRAL 50 TRAVERSE AVEC JEU PAR LA JAMBE ET DE TROUS DEBOUCHANTS 52, PARALLELES AU TROU CENTRAL, DANS CHACUN DESQUELS COULISSE AVEC FROTTEMENT UNE TIGE 54 DONT LA LONGUEUR EST SUPERIEURE A L'EPAISSEUR DE LA PLAQUE INTERMEDIAIRE ET INFERIEURE A L'ECARTEMENT DES PLAQUES DE BUTEE. ON OBTIENT AINSI UN SUPPORT DONT L'EFFET AMORTISSEUR AUGMENTE AVEC L'AMPLITUDE DES OSCILLATIONS.THIS SUPPORT, WHICH INCLUDES A TUBULAR BODY 10 FIXED TO THE BEARING STRUCTURE 16, AN ATTACHING BODY 26 FIXED TO THE OSCILLATING BODY AND CONCENTRICALLY CONNECTED TO THE TUBULAR BODY BY AN ANNULAR ELEMENT 20 IN ELASTOMER AND A FRICTION DAMPER FOR THE OSCILLATION OF THE BODY OF ATTACHMENT RELATING TO THE TUBULAR BODY, IS CHARACTERIZED IN THAT THE ATTACHMENT ORGAN IS PROVIDED WITH A LEG 34, WHICH EXTENDS COAXIALLY INTO THE TUBULAR BODY AND SUPPORTS A PAIR OF CROSS-PLATES OF STOP 38, 40 AXIALLY DISTANT ONE OF THE OTHER AND IN THAT THE TUBULAR BODY SUPPORTS AN INTERMEDIATE PLATE 48 BETWEEN THE TWO STOP PLATES, A PLATE WHOSE THICKNESS IS LESS THAN THE GAP OF THE STOP PLATES AND WHICH IS EQUIPPED WITH A CENTRAL HOLE 50 CROSSES WITH CLEARANCE BY THE LEG AND THROUGH HOLES 52, PARALLEL TO THE CENTRAL HOLE, IN EACH OF WHICH SLIDES WITH FRICTION A ROD 54 WHOSE LENGTH IS GREATER THAN THE THICKNESS OF THE INTERMEDIATE PLATE AND LESS THAN THE DISTANCE OF THE STOP PLATES. THUS IS OBTAINED A SUPPORT WHOSE SHOCK ABSORBING EFFECT INCREASES WITH THE AMPLITUDE OF OSCILLATIONS.
