Zusammenfassung:A vehicle drive-line torsional vibration damper (10 in Fig. 1) which includes an input mass (11) for connection with a vehicle engine and an output mass (12) for connection with a vehicle drive-line, the input and output masses being relatively rotatable against damping means (40, 34D, 34E, 60) to absorb/attenuate alternate torsional vibrations emanating from the engine. The damping means may take numerous forms such as, for example, bob-weight damping linkages (40) which connect the masses for the transmission of drive torque and which provide a speed depending torsional damping effect, springs (34D, 34E) loaded in compression, fluid damping devices and friction damping devices (60). One of the masses (11) has a vibration damping layer (61) applied to one or more parts thereof.
