ELASTIC, HOMOCINETIC SHAFT SEAL AND ARTICULATED SHAFT USING SUCH A JOINT, PARTICULARLY FOR VEHICLES

Abstract

Abstract Translated from French CE JOINT OU ACCOUPLEMENT CONTIENT, DANS UN CORPS 3, PAR EXEMPLE EN RESINE POLYESTER RENFORCEE AUX FIBRES DE VERRE, DES RESSORTS 6 EN METAL ET CAOUTCHOUC 25 DEFINISSANT DES CHAMBRES 9, 10. CELLES-CI CONTIENNENT UN FLUIDE, DU GLYCOL PAR EXEMPLE, ET SONT REUNIES PAR DES PASSAGES 8 EN DEUX SYSTEMES COMMUNICANTS, DONT L'UN EST SOUMIS A COMPRESSION ET L'AUTRE A LA TRACTION A LA TRANSMISSION D'UN COUPLE. LE JOINT EST CAPABLE DE COMPENSER DES DECALAGES AXIAL, RADIAL, ANGULAIRE ETOU TORSIONNEL ENTRE LES ARBRES OU TRONCONS D'ARBRE QU'IL RELIE. IL EST POSSIBLE EN PLUS DE REGLER SA RAIDEUR, C'EST-A-DIRE SON ANGLE DE TORSION EN FONCTION DU COUPLE TRANSMIS POUR PERMETTRE L'ADAPTATION OPTIMALE AU SYSTEME OSCILLANT OU VIBRANT DANS LEQUEL LE JOINT EST INCORPORE. THIS JOINT OR COUPLING CONTAINS, IN A BODY 3, FOR EXAMPLE IN POLYESTER RESIN REINFORCED WITH FIBERS OF GLASS, SPRINGS 6 IN METAL AND RUBBER 25 DEFINING CHAMBERS 9, 10. THEY CONTAIN A FLUID, GLYCOL FOR EXAMPLE, AND ARE JOINED BY PASSAGES 8 IN TWO COMMUNICATING SYSTEMS, ONE OF WHICH IS SUBJECT TO COMPRESSION AND THE OTHER TO TRACTION TO THE TRANSMISSION OF A TORQUE. THE JOINT IS CAPABLE OF COMPENSATION FOR AXIAL, RADIAL, ANGULAR AND OR TORSIONAL OFFSETS BETWEEN THE SHAFTS OR SHAFT TRUNKS THAT IT CONNECTS. IT IS POSSIBLE IN ADDITION TO ADJUST ITS STIFFNESS, THAT IS TO SAY ITS TORSION ANGLE DEPENDING ON THE TRANSMITTED TORQUE TO ALLOW OPTIMAL ADAPTATION TO THE OSCILLATING OR VIBRATING SYSTEM IN WHICH THE SEAL IS INCORPORATED.
