Abstract
A drive system may provide centrifugally driven clutch members into engagement and disengagement using weights between an interface of the clutch members. The weights maybe disposed in races between the clutch members. The weights may move centrifugally within the races pushing the clutch members apart during rotation of an input drive shaft. In some embodiments, two clutch members may provide the engagement and disengagement of the input drive shaft power to a drive output member and a third clutch member may be configured to engage the two clutch members during drive engagement. The third clutch member may be configured to disengage from the two clutch members as a failsafe during, for example, an overspeed condition or a jammed clutch interface.
