ABSTRACT:
A rotary flywheel mechanism comprising a flywheel driven from a wheel driven shaft through a thrust member and angularly spaced balls located in complementary recesses in adjacent faces of the flywheel and the thrust member is disclosed. A locking mechanism is incorporated to prevent operation of the flywheel mechanism until the vehicle has attained a predetermined minimum road speed. The locking mechanism comprises a centrifugally-operable weight carried by the flywheel and which is normally urged inwardly by a spring and into engagement with the thrust member to lock the flywheel and the thrust member against relative movement. The centrifugal force generated at speeds above the minimum speed urges the weight outwardly to unlock the flywheel and the thrust member. The weight may comprise a plunger guided for radial movement in a radial bore in the flywheel, or the weight may comprise a mass carried by a lever which is angularly movable about a pivot parallel to the axis of the shaft.
