Abstract:
1. A one way clutch arranged for coupling a transmission having a stator shaft to a torque converter stator, wherein said torque converter stator comprises an axis of rotation, said one way clutch comprising: a hub comprising an outer circumferential edge having a first wall extending perpendicularly therefrom and an inner circumferential edge having a hub spline arranged thereon, said first wall comprising at least one hub slot, each of said at least one hub slot has a first length; a substantially cylindrical spring ring comprising a second wall, said second wall comprising at least one spring ring slot and at least one spring ring tab arranged adjacent to an open end of said at least one spring ring slot and forming at least a portion of an edge of said at least one spring ring slot, each of said at least one spring ring slot has a second length greater than said first length, said at least one hub slot in registered alignment with said at least one spring ring slot and said at least one spring ring tab arranged within and adjacent to said at least one hub slot and extends radially therethrough; and, a tab plate comprising a circumferential edge having at least one tab plate tab extending radially therefrom, said tab plate arranged axially and rotationally displaceable relative to said hub and said spring ring, said at least one tab plate tab is arranged within said at least one hub slot and/or said at least one spring ring slot, wherein during a lockup condition of said one way clutch, said tab plate is rotationally fixed relative to said hub and said spring ring and said at least one tab plate tab contacts at least one wall of said at least one hub slot and/or said at least one spring ring slot, and during a freewheel condition of said one way clutch, said tab plate rotates relative to said hub and said spring ring and said at least one tab plate tab contacts said at least one spring ring tab.
