Abstract

A power coupling mechanism having fluid dampening device with interfitting members which assist in the absorption and transmittance of stress due to torsion and thrust loads, thus reducing the size of a bearing supporting relatively rotatable parts.

Claims27

Dependent claims

A power coupling mechanism, comprising:

a hub being connectable with an input shaft of a transmission;
a driven plate rigidly connected to said hub;
a bearing supported on said hub;
a drive plate supported on said bearing to allow for relative rotation between said driven plate and said drive plate, said driven plate and said drive plate at least partially defining an annular housing;
a vibration dampening mechanism disposed within said annular housing between said drive plate and said driven plate elastically coupling said drive plate and said driven plate limiting relative rotary displacement between said drive plate and said driven plate;
and
an inertia element rigidly connected to said hub.
