Abstract:
A friction clutch for acting between an internal combustion engine and a torque transmission unit, and including a flexible torque transmitting flywheel (5, 6) comprising a flexible disc (5) with, at its inner periphery, a first portion (51) for coupling the flexible disc (5) to a shaft of the internal combustion engine for rotation therewith, and at its outer periphery a second portion (53) for supporting a plate (6) of the clutch, in which the friction clutch has, below 200 hertz, a first resonant frequency (F1) and a second resonant frequency (F2) which is higher than the first resonant frequency (F1), wherein a ratio of said second resonant frequency relative to said first resonant frequency is at least 1.5.
