Abstract
A series damper, including: a first damper with a flange and a cover plate; and a second damper with first and second cover plates and a flange. The flange and the cover plate for the first damper are rotationally frictionally engaged and the flange for the second damper rotates free of frictional engagement with the first and second cover plates. The series damper includes a resilient element arranged to cause the frictional engagement of the flange and the cover plate for the first damper. In some aspects, the resilient element is frictionally engaged with the cover plate for the first damper and is arranged to frictionally engage a turbine hub for a torque converter. In some aspects, the resilient element is rotationally connected to the flange for the first damper. In some aspects, the flange for the first damper includes the second cover plate for the second damper.
