Double damped flywheel, especially for automotive vehicles

摘要

The present invention is concerned with a double damped flywheel for use in automobiles. The flywheel has two masses which delimit a first sealed cavity. The first sealed cavity is filled with a first fluid and has a resilient spring disposed within its cavity. A viscous damper is mechanically interposed between the two masses and includes a second sealed cavity which is delimited by the two masses. The second sealed cavity is filled with a second fluid which is different from the first fluid. The second sealed cavity is located generally inwardly of the first sealed cavity.
