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.

Abstract: A torque converter, including: a cover; a first through bore for receiving a transmission input shaft; a clutch including a piston plate; a plurality of fasteners connected to the cover; and a plate connected to the cover. The plate includes a radially aligned wall including a plurality of openings in which the plurality of fasteners is disposed; a second through bore at least partially aligned, in an axial direction, with the first through bore; and a plurality fins extending from the radially aligned wall in the axial direction. Each fin includes a first end aligned with the first and second through bores in the axial direction. Each fin includes a second end disposed radially within the plurality of openings. A space, aligned with an axis of rotation for the torque converter and the second through bore, is formed between the respective first ends.
