Abstract:
Apparatus for damping vibrations between an engine and a clutch in a power train, comprising a first flywheel connectable with an output element of the engine; a second flywheel having a friction surface engageable with a clutch plate of the clutch, said first flywheel comprising sections defining a chamber including a radially outer portion which constitutes an annular compartment for a supply of viscous medium which at least partially fills said compartment, said flywheels being rotatable relative to each other in clockwise and counterclockwise directions; and a damper device movably connecting said flywheels to each other and including energy storing elements disposed in said compartment and arranged to store energy in response to rotation of said flywheels relative to each other in either of said directions, at least one of said sections of said first flywheel including a portion disposed radially outwardly of said energy storing elements and extending substantially axially of said first flywheel, said energy storing elements bearing against said portion of said at least one section under the action of centrifugal force in response to rotation of said first flywheel, one of said sections of said first flywheel further comprising a substantially disc-shaped part having a radially inner portion connectable with the output element of the engine and said damper device further comprising a substantially disc-shaped member arranged to transmit torque between said flywheels and having portions extending into said compartment and engaging said energy storing elements.
