Abstract

L'INVENTION CONCERNE UN DISPOSITIF DE REGLAGE AUTOMATIQUE A FRICTION POUR CYLINDRE DE FREIN DE ROUE. CE DISPOSITIF COMPREND UNE BAGUE DE FRICTION 2 MONTEE AVEC EXPANSION SUR UNE BROCHE DE GUIDAGE 3 FIXEE AU FOND DU CYLINDRE DE FREIN DE ROUE 9. CETTE BAGUE EST RETENUE, AVEC JEU RADIAL ET AXIAL, DANS UNE GORGE ANNULAIRE 1 DU PISTON 4. CETTE BAGUE A, AVANT MONTAGE, UN DIAMETRE EXTERIEUR LEGEREMENT INFERIEUR A CELUI DU TROU D ET EST EXPANSEE, APRES INTRODUCTION DANS LE TROU, JUSQU'A UN DIAMETRE INTERIEUR ENCORE INFERIEUR A CELUI D DE LA BROCHE. L'INVENTION S'APPLIQUE AUX DISPOSITIFS DE REGLAGE AUTOMATIQUE POUR CYLINDRES DE FREIN A TAMBOUR.THE INVENTION RELATES TO AN AUTOMATIC FRICTIONAL ADJUSTING DEVICE FOR A WHEEL BRAKE CYLINDER. THIS DEVICE INCLUDES A FRICTION RING 2 MOUNTED WITH EXPANSION ON A GUIDING PIN 3 FIXED TO THE BOTTOM OF THE WHEEL BRAKE CYLINDER 9. THIS RING IS RETAINED, WITH RADIAL AND AXIAL CLEARANCE, IN AN ANNULAR GROOVE 1 OF THE PISTON 4. THIS RING A, BEFORE ASSEMBLY, AN OUTER DIAMETER SLIGHTLY LOWER THAN THAN D HOLE AND IS EXPANDED, AFTER INSERTING THE HOLE, TO AN INSIDE DIAMETER STILL LOWER THAN D OF THE SPINDLE. THE INVENTION APPLIES TO AUTOMATIC ADJUSTING DEVICES FOR DRUM BRAKE CYLINDERS.
