Patent ID: 11518230

Abstract:
A clutch device includes a main clutch, a pilot clutch, and an inner cage. The main clutch has a friction pack, a pressure device for pressing the friction pack, and a ramp system for moving the pressure device. The pilot clutch is for transmitting torque to the ramp system and can be opened and closed by moving the counter-plate. The pressure device can be moved by the counter-plate. The friction pack is mechanically connected to the inner cage and an outer cage. The ramp system includes a first ramp element arranged on the inner cage, a freewheel, and a second ramp element. The freewheel blocks rotary movement of the first ramp element in a first rotational direction and allows rotary movement in an opposite rotational direction. The first and second ramp elements, and the pilot clutch, are mechanically connected to the inner cage when the pilot clutch is closed.
