Torsional vibration damper for hydrokinetic torque coupling device

摘要

A torsional vibration damper of a hydrokinetic torque coupling device, comprises a driven plate rotatable about a rotation axis, an intermediate plate rotatably mounted about the driven plate coaxially with the rotation axis, a back plate rotatably mounted about the intermediate plate coaxially with the rotation axis, a plurality of circumferentially acting elastic members interposed between the driven plate and the intermediate plate, and a damper retainer plate non-moveably secured to the back plate coaxially with the rotation axis. The damper retainer plate is operatively connected to the elastic members. The driven plate, the intermediate plate and the back plate are aligned with each other along a radial axis perpendicular to said rotation axis.

1. A torsional vibration damper for a hydrokinetic torque coupling device, comprising:
a driven plate rotatable about a rotation axis, said driven plate having opposite radially extending planar first and second driven plate surfaces and a first thickness extending between said first and second driven plate surfaces; an intermediate plate rotatably mounted about said driven plate coaxially with said rotation axis, said intermediate plate having opposite radially extending planar first and second intermediate plate surfaces and a second thickness extending between said first and second intermediate plate surfaces; a back plate rotatably mounted about said intermediate plate coaxially with said rotation axis, said back plate having opposite radially extending planar first and second back plate surfaces and a third thickness extending between said first and second back plate surfaces; a plurality of circumferentially acting elastic members interposed between said driven plate and said intermediate plate; and a first damper retainer plate non-moveably secured to said back plate coaxially with said rotation axis, said first damper retainer plate operatively connected to said elastic members; said first driven plate surface, said first intermediate plate surface, and said first back plate surface extending radially in coplanar alignment with one another along a first radial axis perpendicular to said rotation axis; and said second driven plate surface, said second intermediate plate surface, and said second back plate surface extending radially in coplanar alignment with one another along a second radial axis perpendicular to said rotation axis.
