The present invention relates to a clutch (100) comprising: a fixed hub (101, 1101) comprising a central coupling hole (301) configured for coupling with a rotating shaft (1200); a movable hub (102, 1102) configured for being mounted along an axial direction onto the fixed hub (101, 1101); a plurality of discs (103) interposed between the fixed hub (101, 1101) and the movable hub (102, 1102). The fixed hub (101, 101) and the movable hub (102, 1102) are shaped so as to rotate jointly with each other and so as to axially slide with each other, getting farther or closer to each other so that the fixed hub (101, 1101) and the movable hub (102, 1102) exert a variable axial load onto the plurality of discs (103), thereby transmitting a torque. The movable hub (102, 1102) comprises a central access hole (302) that is configured for allowing access to said central coupling hole (301) passing internally through the plurality of discs (103) interposed, so as to operate locking means (1201) for the coupling with the rotating shaft (1200). The present invention also relates to a method for mounting a clutch.

The present invention relates to a clutch (100) comprising: a rotatable housing (101); a fixed hub (201) internal to the housing (101) and a movable hub (202) axially mounted onto the fixed hub (201); a plurality of discs (204) interposed between the fixed hub (201) and the movable hub (202). 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), to selectively transmit a torque. The clutch (100) further comprises a pressure plate assembly (208) for controlling the variable axial load, including a centrifugal assembly (210) comprising: a rotatable mass holder (211) and a plurality of mass elements (212) radially disposed. Each mass element (212) comprises a pivot (301) and is configured for a displacement (1002) by pivoting under centrifugal effects. The mass elements (212) are thus configured for exerting an axial thrust within the pressure plate assembly (208), to bring 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) comprises a main body (302) and a column element (303) which connects the pivot (301) with the main body (302).

A clutch adapted to transmit the motion from a driving shaft to a driven shaft, having an axis of rotation coaxial to the driven shaft and comprising, a ring gear, a first bell integral in rotation with the ring gear and coaxial to the axis of rotation, an axially fixed hub internal to the first bell and coaxial to the axis of rotation, an axially movable pressure assembly including a disk-pusher element, a disk pack, a plurality of elastic elements, and a centrifugal assembly. The clutch comprises at least one first clearance-recovery device of a unidirectional type, adapted to limit the separation of the disk-pusher element from the axially fixed hub and from the disk pack, and a second clearance-recovery device of a unidirectional type, adapted to enable an axial movement of the centrifugal assembly only towards the disk-pusher element.
