Title:
TORQUE CONVERTER WITH TURBINE MASS ABSORBER
Document Type and Number:
WIPO Patent Application WO/2011/130182
Kind Code:
A3
Abstract:
A damper assembly for a torque converter includes a drive side elastic element arranged for transmitting torque to a turbine for the torque converter in a first direction and a coast side elastic element, separate from the drive side elastic element, arranged for transmitting torque to the turbine in a second direction opposite the first direction. In an example embodiment, a slope of a torque curve for the damper remains constant in a transition region between transmitting torque to the turbine in the first direction and transmitting torque to the turbine in the second direction. In an example embodiment, the damper assembly includes an input damper and an output damper. The elastic elements are disposed in a torque path between the input damper and the output damper. In an example embodiment, the input damper is selectively engaged with a cover for the torque converter and the output damper is drivingly engaged with an output hub for the torque converter.
