PCT No. PCT/EP98/00432 Sec. 371 Date Jul. 8, 1999 Sec. 102(e) Date Jul. 8, 1999 PCT Filed Jan. 27, 1998 PCT Pub. No. WO98/34051 PCT Pub. Date Aug. 6, 1998The invention relates to a transmission in which the input power is either directly transmitted by an input shaft (2) to an output shaft (17) or indirectly transmitted via a continuously variable transmission (5), in particular a transmission with toroidal races (6, 8 and 7, 9 respectively) which work together in pairs and between which rotate rolling bodies (10) and a planetary gear (18). According to the invention the first power range corresponds to a first forward travelling speed range in which the input power is transmitted via the variator (5) to the output shaft (17) and the planetary gear (18) revolves as a unit, and one other power range follows the first power range and corresponds to a range of higher forward travelling speeds in which the input power is divided and supplied to the planetary gear directly and via the variator (5) which totals and transmits it to the output shaft (17). By the plurality of possible arrangements, in particular of the variator and planetary gear, the transmission according to the invention is suitable for use in practically all vehicles.
