Abstract
A torque converter is provided. The torque converter includes an axially movable turbine piston and a damper assembly fixed to the turbine piston. The damper assembly includes a first cover plate, a second cover plate, a plurality of fasteners fixing the first cover plate and the second cover plate together such that the second cover plate is spaced from the first cover plate, a first drive flange axially between the first and second cover plates, a second drive flange axially between the first and second cover plates and an elastic element axially between the first and second cover plates. The first cover plate, the second cover plate, the second flange, the fasteners and the elastic element are axially movable with the piston turbine independently of the drive flange. The elastic element is configured to create a controlled rotational hysteresis between the second drive flange and the first and second cover plates during the axial movement of the first cover plate, the second cover plate, the second flange, the fasteners and the elastic element. A method of forming a torque converter is also provided.
