ABSTRACT:
An apparatus for damping torsional vibrations, particularly between coaxial primary and secondary masses of a composite flywheel in the power train between the engine and the transmission of a motor vehicle, has at least one coil spring or torsion spring which extends around the common axis of the two masses, which is stressed at least in the radial direction, and which is in a mere frictional (rather than positive) torque transmitting engagement with at least one of the masses. The spring can be installed to transmit torque from the secondary mass to the primary mass and/or vice versa, and such spring can operate in series with a damper between the primary and secondary masses.
