Abstract

See full text

One aspect is a wrap spring clutch with a rotatable input and a spring having a first and a second end and having an equilibrium state and a flexed state, the spring engaged with the input through one of the first and second ends such that the spring rotates with the input and with an input torque transmitted exclusively through one of the first and second ends when the input rotates. A damper mechanism is engaged with one of the first and second ends such that the damper mechanism causes the spring to change from its equilibrium to its flexed state when the input transitions from stationary to rotational, and such that the damper mechanism allows the spring to change from its flexed to its equilibrium state when the input transitions from rotational to stationary. A rotatable output is positioned relative to the spring such that the output synchronously rotates with the input when the spring is in its flexed state and rotates independently of the input when the spring is in its equilibrium state.
