Patent number: 10151376Abstract: A torque converter is provided. The torque converter includes an impeller including a plurality of impeller blades and a radially extending wall radially outside of the impeller blades and a turbine piston axially movable with respect to the impeller. The turbine piston includes a plurality of turbine blades and an outer radial extension radially outside of the turbine blades. The torque converter also includes a clutch assembly axially between the radially extending wall of the impeller and the outer radial extension of the turbine piston. The clutch assembly includes a first clutch plate rotationally fixed to the impeller and a second clutch plate rotationally fixed to the turbine piston. A portion of the clutch assembly extends between the turbine blades or the impeller blades. A method of constructing a torque converter is also provided.Type: GrantFiled: April 7, 2017Date of Patent: December 11, 2018Assignee: Schaeffler Technologies AG & Co.

Patent number: 8789669Abstract: 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.Type: GrantFiled: June 21, 2011Date of Patent: July 29, 2014Assignee: Schaeffler Technologies GmbH & Co.
