Patent ID: 11255385

Abstract:
A clutch (100) having: a fixed hub (201), a movable hub (202), a plurality of discs (204). The fixed hub (201) and the movable hub (202) axially slide, getting farther or closer so as to transmit a variable axial load onto the discs (204). The clutch (100) has a pressure plate assembly (208) including a centrifugal assembly (210), having: a rotatable mass holder (211) and a plurality of mass elements (212) radially disposed. Each mass element (212) has a pivot (301) and is configured for a displacement (1002) by pivoting under centrifugal effects. The mass elements (212) are configured for bringing the movable hub (202) closer to the fixed hub (201), so as to increase the variable axial load and allowing the clutch (100) (automatic) engagement. Each mass element (212) has a main body (302) and a column element (303) which connects the pivot (301) with the main body (302).
