Patent number: 8882468Abstract: A blade family for torque converters with a first blade having a first shape and flow guiding surface and a second blade having a second shape and flow guiding surface. The first surface is different from the second surface and the first shape is the same as a portion of the second shape, or the second shape is the same as a portion of the second shape. In an example embodiment of the invention, at least one of the first or second blades includes holes or slots. In an example embodiment of the invention, the first blade includes more material than the second blade. The first and second blades may have respective mounting tabs, with the second blade having fewer mounting tabs than the first blade. Other example aspects of the present invention broadly comprise a torque converter with a plurality of first and/or second blades from the blade family.Type: GrantFiled: December 20, 2010Date of Patent: November 11, 2014Assignee: Schaeffler Technologies GmbH & Co.

Patent number: 7887240Abstract: A thrust washer for a torque converter, including a front surface and at least one first channel. The at least one channel is at least partially enclosed by the front surface and is in fluid communication with an inner circumference and an outer circumference for the thrust washer. The front surface is arranged to engage a cover for the torque converter. In some aspects, the at least one channel is fully enclosed by the front surface. The thrust washer also includes a back surface, oppositely disposed from the front surface. The at least one channel is at least partially enclosed by the back surface. In some aspects, the thrust washer includes a front piece and a back piece matingly engaged and configured to form the at least one channel. The front and back pieces are fixedly secured or removably secured.Type: GrantFiled: December 12, 2006Date of Patent: February 15, 2011Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Bhaskar Marathe, Steven Olsen
