Claim Text:
1. A transmission clutch damper assembly, comprising: an outer carrier including an outer circumference with inner and outer splines; first and second spring retainer plates located within the outer carrier, each of the spring retainer plates having an axial flange with spring stops, a radial flange, and fingers or teeth that engage the outer carrier inner spline; at least one spring retained in each of the first and second spring retainer plates by the respective axial flanges and contact between respective first and second spring ends and the respective spring stops; a hub having an annular hub body with at least two radially outwardly extending castles so that upon rotation of the outer carrier in a first direction relative to the hub, the castles are acted upon by each of the first spring ends to create spring damping in the first direction, and upon rotation of the outer carrier in a second direction relative to the hub, the castles are acted upon by each of the second spring ends to create spring damping in the second direction, and a spline located on the hub that is adapted to drivingly engage corresponding splines on a transmission drive shaft; and a drive ring located between the first and second spring retainer plates, the drive ring including fingers or teeth that engage the outer carrier inner spline and drive fingers extending radially inwardly from the drive ring into a space axially between the respective springs of the first and second spring retainer plates, the drive fingers radially overlapping the castles of the hub to limit a maximum relative rotation of the outer carrier relative to the hub.
