Abstract

A torque converter having a first damper stage, a second damper stage, a floating flange torsionally connecting the first and second damper stages, an inertia element, and a tuned torsion damper. The torsion damper connects the inertia element and the flange. In a preferred embodiment, the inertia element is a turbine. In one embodiment, the first damper stage is a radially outer damper stage and the second damper stage is a radially inner damper stage. In another embodiment, the torsion damper generates a friction torque when rotated.
