Abstract
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.
Claims5
A double damped flywheel for an automotive vehicle, said flywheel comprising a first mass and a second mass coaxial with said first mass, said masses being mounted for relative rotation with respect to each other against the action of resilient means, said masses delimiting a first sealed cavity, mounting means for mounting said resilient means within said first sealed cavity, said first sealed cavity being filled with a first fluid, viscous damping means being mechanically interposed between said two masses and comprising elements of said two masses to define together a second sealed cavity, said second sealed cavity being disposed generally inwardly of said first sealed cavity, said second sealed cavity being filled with a second fluid, said second fluid being different from said first fluid, said second sealed cavity being located close to the axis of rotation of said double flywheel, radially inwardly of said resilient means.
