Abstract

L'INVENTION A TRAIT A UN RALENTISSEUR PERFECTIONNE. ELLE A POUR OBJET UN FREIN COMPRENANT UN BOITIER NON ROTATIF ET UN ARBRE D'ENTRAINEMENT MONTE DE FACON A POUVOIR TOURNER A L'INTERIEUR, UN ENSEMBLE ANNULAIRE DE DISQUES ROTORIQUES ASSUJETTIS EN ROTATION AUDIT ARBRE, LESDITS DISQUES ROTORIQUES AYANT DES COTES DE FRICTION OPPOSES, UN ENSEMBLE DE DISQUES STATORIQUES EMPECHES DE TOURNER PAR RAPPORT AU BOITIER ET INTERCALES AVEC LESDITS DISQUES ROTORIQUES, LES DISQUES STATORIQUES AYANT DES FACES LATERALES DE FRICTION OPPOSEES, DES MOYENS POUR BLOQUER SELECTIVEMENT LES COTES DE FRICTION DESDITS ENSEMBLES DE DISQUES POUR EMPECHER UNE ROTATION DE L'ARBRE PAR RAPPORT AU BOITIER. LE FREIN COMPORTE DES PASSAGES DELIMITES PAR UNE PARTIE DU BOITIER DISPOSES CIRCONFERENTIELLEMENT AUTOUR DE LA PERIPHERIE EXTERIEURE DES DISQUES ROTORIQUES ET STATORIQUES POUR PERMETTRE UN PASSAGE D'UN LIQUIDE DE REFROIDISSEMENT PRESSURISE VERS LA PERIPHERIE EXTERIEURE DES DISQUES ROTORIQUES ET STATORIQUES, ET DES PASSAGES D'ECOULEMENT DIRIGEANT LE LIQUIDE RADIALEMENT VERS L'INTERIEUR ENTRE LES JEUX DE DISQUES. APPLICATION, NOTAMMENT AU FREINAGE DE VEHICULES TERRESTRES.THE INVENTION IS ABOUT A PERFECTED RETARDER. IT IS A BRAKE INCLUDING A NON-ROTATING BOX AND A DRIVE SHAFT MOUNTED TO BE ABLE TO TURN INSIDE, AN ANNULAR ASSEMBLY OF ROTORIC DISCS SUBJECT TO ROTATION AUDIT SHAFT, THE SAID ROTORIC DISCS WITH OPPOSITE FRICTION SIDES, A SET OF STATORIC DISCS PREVENT FROM ROTATING WITH RESPECT TO THE CASE AND INTERCALED WITH THE SAID ROTORIC DISCS, THE STATORIC DISCS HAVING OPPOSED SIDE FRICTION FACES, MEANS FOR SELECTIVELY BLOCKING THE FRICTION SIDES OF THE SAID DISCS FOR THE SAID SETS SHAFT IN RELATION TO THE BOX. THE BRAKE INCLUDES PASSAGES DELIMITED BY A PART OF THE CASE ARRANGED CIRCUMFERENTIALLY AROUND THE EXTERNAL PERIPHERY OF THE ROTORIC AND STATORIC DISCS TO ALLOW A PASSAGE OF A COOLING LIQUID PRESSURIZED TOWARDS THE EXTERNAL PERIPHERY OF THE ROTORIC AND STATOR DISCS DIRECTING LIQUID RADIALLY INWARD BETWEEN DISC SETS. APPLICATION, IN PARTICULAR TO THE BRAKING OF LAND VEHICLES.
