<p>The present invention relates to a flywheel having mass that is a function of its angular frequency. The variable mass flywheel includes: a primary flywheel having an axis of rotation; a secondary flywheel coaxial with the primary flywheel and having a mating portion that either circumscribes the primary flywheel or inscribes the primary flywheel; a friction disc radiating from the primary flywheel; a drive plate radiating from the mating portion of the secondary flywheel and lapping a portion of the friction disc; a coupler urging the friction disc and the drive plate into abutment whereby the primary flywheel and the secondary flywheel are coupled for unified rotation; a detector for detecting the angular frequency of the primary flywheel, the detector being operable to assume a first state when the angular frequency is less than a predetermined angular frequency and assume a second state when the angular frequency is greater than the predetermined angular frequency; and a decoupler responsive to the state of the detector, operable when the detector is in the second state to overcome the coupler and urge the friction disc and the drive plate out of abutment whereby the primary flywheel and the secondary flywheel are decoupled for separate rotation.</p> |
