Abstract:
Apparatus for damping torsional vibrations, comprising:first and second torque transmitting devices turnable with and relative to each other about a common axis and respectively arranged to receive torque from a rotary output element of a driving unit and to transmit torque to a rotary input element of a driven unit; a damper arranged to yieldably oppose rotation of said devices relative to each other and including elastically deformable energy storing means engageable by portions of said devices; and inserts interposed between said portions of said devices on the one hand and said energy storing means on the other hand, said inserts having anvils arranged to abut each other in response to turning of at least one of said devices relative to the other of said devices through predetermined angles, wherein said energy storing means is disposed at a first radial distance from said axis and said anvils are disposed radially inside of said energy storing means at a lesser second radial distance from said axis.
