The invention provides a continuously variable transmission drive system (1) comprising a central friction drive disk (27); two rollers (159; 203) clamped against two opposite sides (30) of the drive disk (27) with their outer rims (169; 205) in friction-drive contact with drive disk (27) and being movable across the disk radius to alter the gear ratio; an input drive shaft (15) connected to the rollers (159; 203) for driving the rollers (159; 203); and a hinged clamping assembly (21; 23) which is associated with the drive shaft (15) and configured for forcibly clamping the two rollers (159; 203) around the drive disk (27) with a variable clamping force that is proportional to the input torque on drive shaft (15).
