ABSTRACT:
A torque-responsive clutch has an output shaft and an output pulley mounted with respect to the shaft. The output pulley includes a first sheave fixed with respect to the shaft and a second sheave axially movable with respect to the shaft. A helix is mounted with respect to the shaft. In the improvement, a roller container is mounted for driven engagement with the shaft and such container has an interior surface with a plurality of helix-contacting devices, e.g., rollers, mounted adjacent thereto. The helix extends into the container and contacts the devices. In other aspects of the improved clutch, the roller container and the second sheave define a chamber and the helix-contacting devices are confined in such chamber.
