Abstract
A transmission clutch damper assembly having an outer carrier with at least one spring retainer plate located therein. At least one spring is retained by stops in the spring retainer plate. A hub having radially outwardly extending castles is provided. Upon rotation of the outer carrier in a first direction relative to the hub, the castles are acted upon by a first spring end, and upon rotation of the outer carrier in a second direction relative to the hub, the castles are acted upon a second spring end. Two of the spring retainer plates can be provided with a drive ring therebetween adapted to contact the castles dependent upon a relative rotational position of the hub and the outer carrier, establishing a direct drive connection.
Claims18
A transmission clutch damper assembly, comprising:
- an outer carrier;
- at least one spring retainer plate located within the outer carrier and having an axial flange with spring stops, a radial flange, and fingers or teeth that engage an inner surface of the outer carrier;
- at least one spring retained in the at least one spring retainer plate by the axial flange and contact between first and second spring ends and the spring stops;
- and
- 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 the first spring end, and upon rotation of the outer carrier in a second direction relative to the hub, the castles are acted upon by the second spring end, and a spline located on the hub that is adapted to drivingly engage corresponding splines on a transmission drive shaft.
An automatic transmission comprising:
- a transmission input shaft;
- a damper assembly connected to the input shaft, the damper assembly including:
- an outer carrier;
- 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 an inner surface of the outer carrier,
- at least one spring retained in each of the spring retainer plates by the axial flange and contact between first and second spring ends and the spring stops, and
- 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 the first spring ends, and upon rotation of the outer carrier in a second direction relative to the hub, the castles are acted upon by the second spring ends, and a spline located on the hub that drivingly engages corresponding splines on the transmission input shaft.
