ABSTRACT:
A filtering device is provided for filtering vibrations transmitted by a rotating engine component (11) adapted to drive in rotation an output shaft (19), which device comprises a drive shaft damper (20) tuned at a frequency substantially locked within a range of frequencies to be damped: electromagnetic modulating systems (23) are designed to adapt the frequency of the damper (20) to the frequency of the vibrations transmitted by the rotary component (11). Moreover, a transmission is provided for motor vehicle comprising a drive shaft (11), linked to a rotary component formed by the motor vehicle engine crankshaft, an output shaft (19) linked to the drive shaft releasable via a clutch, a gearbox (50), the output shaft (19) being the input shaft of the gearbox (50), a filtering device being provided for filtering vibrations emitted, hence transmitted, by the rotary component.
