Abstract
A transmission has a gear system (34) which may be in the form of an orbit system (32, 35) or a planetary orbital spur system. The gear systems include a control gear (32) which is controlled to determine the drive ratio of the transmission. The control gear is controlled by a momentum control which includes a disc (23) and a slide (25) which carries a magnet (30) for selectivity allowing or preventing rotation of the disc (23) to in turn change the speed of rotation of the control gear (32). Alternatively, the momentum control can be formed from moveable masses which move radially outwardly relative to the control shad to change the speed of rotation of the control gear.
