Apr 20, 2011
Appl. No.:

13/090634
Inventors:

Larry Boigegrain - Wooster OH, US
Patrick Lindemann - Wooster OH, US
Assignee:

SCHAEFFLER TECHNOLOGIES GMBH & CO. KG - Herzogenaurach
International Classification:

F16C 3/02
F16L 55/00
US Classification:

464183, 137561 A
Abstract:

A flat blade for a transmission input shaft includes a substantially rectangular body portion for insertion in a center bore of the input shaft and at least one radial blade segment extending from the body portion. The radial blade segment is arranged for assembly proximate a distal end of the input shaft and for extending radially beyond the center bore. In an example embodiment, the radial blade segment is substantially rectangular in shape. In an example embodiment, the radial blade segment is a pair of radial blade segments extending in opposing directions. In an example embodiment, the body portion is arranged for press-fitting into the center bore.

International Classification:

F16H 45/02
US Classification:

192 328
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.
