Abstract:
A damper system includes a turbine shaft rotatably connected to a torque converter having a clutch. A hydraulically actuated clutch is coupled to the turbine shaft. A first spring cage has a first cage portion connected to the hydraulically actuated clutch and a second cage portion connected to a friction plate. A first spring set is connected to the first and second cage portions. Springs of the first spring set are deflected by axial rotation between the first and second cage portions when the torque converter clutch is engaged. A second spring cage has a first cage section connected to the hydraulically actuated clutch and a second cage section connected to a torque converter turbine. A second spring set has second springs having a spring constant different than the first spring set. The second spring set springs are deflected by axial rotation between the first and second cage sections.
