Abstract:
1. An overrunning, isolating decoupler pulley, comprising: a shaft including one or more radially outwardly extending paddles coupled thereto; a pulley body disposed about the shaft and including one or more radially inwardly extending protrusions coupled to the pulley body, the pulley body and shaft rotatable with respect to each other in a first direction by at least a first angular displacement and in an opposing second direction by at least a second angular displacement; one or more engagement features that engage upon sufficient rotation between the pulley body and the shaft, wherein the one or more engagement features, when engaged, prevent further rotation between the pulley body and the shaft in a given direction; a resilient member disposed between the pulley body and the shaft, wherein the resilient member is compressed by the one or more engagement features of the pulley body and the shaft upon sufficient rotation between the pulley body and the shaft; and a hard stop comprising one or more features formed on a radially outwardly facing surface of at least one of the one or more radially outwardly extending paddles having a geometry to interface with the one or more radially inwardly extending protrusions to prevent full compression of the resilient member.
