IN THIS BRAKE DEVICE (7) THE MAGNETS (59,60) ARE ARRANGED ON A FRAME (14) WHICH IS FASTENED IN TURN TO THE BEARING PEDESTAL OF A DRIVE MACHINE. THE FRAME CONSISTS OF STABILIZERS (63,64), AND OF MAGNET CARRIES (61,62) ON WHICH THE MAGNETS (59,60) ARE IMMOVABLY FASTENED. THE MAGNETS (59,60) ACT ON DISK ARMATURES (57,58) ARRANGED ON BRAKE ARMS (8,9). THE MAGNETIC FORCES ACT IN OPPOSITION TO THE SPRING FORCES OF THE COMPRESSION SPRINGS (12,13) AND RELEASE THE BRAKE SHOES (51,52) FROM A BRAKE DRUM, THE FORCES WHICH THEN OCCUR BEING ABSORBED BY THE FRAME (14).(FIG.2)
