Abstract
The over-running clutch pulley of the preferred embodiments of the invention includes a sheave member defining a sheave input surface adapted to engage an input device, a hub member defining a hub output surface adapted to engage an output device, and a clutch cartridge. The clutch cartridge includes a sheave engagement sleeve coupled to a sheave cartridge surface of the sheave member, a hub attachment sleeve coupled to a hub cartridge surface of the hub member, and a coil spring having the first end attached to the hub attachment sleeve. The coil spring is adapted to engage the sheave engagement sleeve upon the acceleration of the sheave member in a first rotational direction relative to the hub member, and to disengage the sheave engagement sleeve upon the deceleration of the sheave member in the first rotational direction relative to the hub member.
