Over-running clutch pulley with clutch cartridge

摘要

The over-running clutch pulley (10) of the preferred embodiments of the invention includes a sheave member (12) defining a sheave input surface (14) adapted to engage an input device, a hub member (16) defining a hub output surface (18) adapted to engage an output device, and a clutch cartridge (20). The clutch cartridge includes a sheave engagement sleeve (22) coupled to a sheave-cartridge surface (24) of the sheave member (12), a hub attachment sleeve (26) coupled to a hub-cartridge surface (28) of the hub member (16), and a coil spring (30) having the first end (32) attached to the hub attachment sleeve (26). The coil spring (30) is adapted to engage the sheave engagement sleeve (22) upon the acceleration of the sheave member (12) in a first rotational direction relative to the hub member (16), and to disengage the sheave engagement sleeve (22) upon the deceleration of the sheave member (12) in the first rotational direction relative to the hub member (16).
