Abstract
A continuously variable transmission system designable compact in size and manufacturable at a reduced cost by reducing the number of component parts and securing a maximum transmission ratio width. A toroidal continuously variable transmission has an input member connected to an output shaft of a prime mover, and an output member for outputting rotation of the input member at a continuously variable transmission ratio. A planetary gear mechanism has a first element connected to the output member, a second element connected to drive wheels, and a third element. A first clutch establishes and releases connection between the first element and the second element. A first gear train and a second gear train having a larger gear ratio, are arranged between the output shaft and the third element in parallel. Second and third clutches establish and release respective connections of first and second gear trains.
