SAFETY FRICTION CLUTCH Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: driving 1 and driven 2 clutch members are coupled through main 3 and additional 4 friction disks. Main pressing disk 5 is interposed between friction disks 3 and 4, and additional pressing disk 6 is interposed between friction disk 4 and pressing spring 7. Main pressing disk 5 and additional pressing disk 6 are mounted for permitting axial and periphery movements with respect to clutch member 1. Balls 9 of the main pressing out stabilizing unit and balls 10 of the additional pressing out stabilizing unit are positioned in respective sockets of varying depth. When a load is applied to balls 9 and 10, forces occur that reduce the pressing force of the disk friction surfaces. EFFECT: improved accuracy of clutch actuating. cl, dwg
