ABSTRACT:
A torsional-vibration damper includes a primary element operatively connected for rotation with a prime mover and a secondary element operatively connected with the input to a transmission. A spring mechanism is operatively disposed between and adapted to control the primary element and the secondary element in damped torque translational relationship. The torsional-vibration damper also includes a friction device having a plurality of fiction blocks that frictionally join the primary element with the secondary element. The secondary element includes an output-side member having a first axial ridge and a drive-side member having a second axial ridge. The output-side member and the drive-side member operatively encompass the primary element and the first axial ridge overlaps the second axial ridge. The first and the second axial ridges thereby cooperate to provide a double layer of radial support for the spring mechanism.
