Abstract
LE BUT DE L'INVENTION EST DE REALISER UN DISPOSITIF DE FREIN QUI SOIT APPROPRIE POUR ETRE UTILISE AUSSI BIEN DANS UN FREIN CHARGE PAR UN RESSORT QUE DANS UN FREIN CHARGE PAR UNE PRESSION. LE CARTER ET L'ARBRE DU MOTEUR, MONTES ROTATIFS L'UN PAR RAPPORT A L'AUTRE, COMPORTENT DES DISQUES DE FREIN 3, 4 ET SONT ATTAQUES PAR UNE PIECE MOBILE 10 QUI EST CHARGEE PAR DES RESSORTS 16 OU 17 SUR UNE FACE ET SOUMISE A UNE PRESSION HYDRAULIQUE SUR SON AUTRE FACE. UNE CHAMBRE DE PRESSION 8 EST EN OUTRE DELIMITEE PAR UNE PLAQUE ANNULAIRE 9 MONTEE SUR UN ARBRE 2. UNE PIECE MOBILE 10 AYANT DEUX COURONNES 12, 13 S'ETENDANT EN SENS OPPOSES SUR SA PERIPHERIE EST EN APPUI D'UNE PART SUR DES DISQUES DE FREIN 4 DE L'ARBRE 2 ET D'AUTRE PART SUR DES RONDELLES 16 FORMANT RESSORTS. LORSQUE LA CHAMBRE 8 DU CYLINDRE N'EST PAS SOUS PRESSION LES RESSORTS 16 PROVOQUENT LE SERRAGE DES DISQUES DE FREIN. LA PIECE MOBILE 10 ET LA PLAQUE ANNULAIRE 9 PEUVENT ETRE MONTEES EN SENS OPPOSE DANS LE CAS D'UN FREIN CHARGE PAR UNE PRESSION.THE OBJECT OF THE INVENTION IS TO ACHIEVE A BRAKE DEVICE THAT IS SUITABLE FOR USE AS WELL IN A SPRING LOADED BRAKE AS IN A PRESSURE LOADED BRAKE. THE CRANKCASE AND THE MOTOR SHAFT, MOUNTED ROTATING WITH RESPECT TO THE OTHER, HAVE BRAKE DISCS 3, 4 AND ARE ATTACKED BY A MOVING PART 10 WHICH IS LOADED BY SPRINGS 16 OR 17 ON ONE SIDE AND SUBJECTED TO HYDRAULIC PRESSURE ON ITS OTHER SIDE. A PRESSURE CHAMBER 8 IS FURTHER DELIMITED BY AN ANNULAR PLATE 9 MOUNTED ON A SHAFT 2. A MOVABLE PART 10 HAVING TWO CROWNS 12, 13 EXTENDING IN OPPOSITE DIRECTIONS ON ITS PERIPHERY IS BEING ON THE ONE HAND SUPPORTED ON DISCS OF BRAKE 4 OF THE SHAFT 2 AND ON THE OTHER HAND ON WASHERS 16 FORMING SPRINGS. WHEN THE CYLINDER CHAMBER 8 IS NOT UNDER PRESSURE, THE SPRINGS 16 CAUSE THE BRAKE DISCS TO TIGHTEN. THE MOVABLE PART 10 AND THE ANNULAR PLATE 9 CAN BE MOUNTED IN THE OPPOSITE DIRECTION IN THE CASE OF A PRESSURE LOADED BRAKE.

Habituellement, le frein à disque d'un moteur hydraulique est soit chargé par un ressort soit chargé par une pression. Antérieurement il était toujours nécessaire de prévoir des organes différents pour des freins chargés par ressort et pour des freins chargés par une pression, Usually, the disc brake of a hydraulic motor is either loaded by a spring or loaded by pressure. Previously it was always necessary to provide different bodies for brakes loaded by spring and for brakes loaded by pressure,
