Drive clutch with multi-staged displacement rate and a method for controlling a drive clutch

摘要

A drive clutch assembly having a fixed sheave and a moveable sheave rotatable with the drive shaft of an engine comprising a multi-staged speed responsive or displacement system. The speed responsive system initially applies a first displacement rate to the moveable sheave as it moves toward the fixed sheave and applies a second displacement rate to the moveable sheave when the drive clutch assembly reaches a predetermined rotational speed.
