Abstract:
A transmission in which input power, in a first power range, is transmitted by an input shaft (2) to an output shaft (17) via a continuously variable transmission in the form of a variator (5) having a main shaft (4) and toroidal races (6, 8 and 7,9 respectively) which work together in pairs and between which rolling bodies (10) rotate and in a second power range is transmitted via the continuously variable transmission (5) and a planetary gearing (18) of the transmission wherein said first power range corresponds to a first forward travelling range in which the input power is transmitted via said variator (5) to said output shaft (17) and said planetary gearing (18) revolves as a unit and in the second power range which corresponds to a range of higher forward traveling speeds, and said variator (5) and said planetary gearing (18) are disposed consecutively and the exit of said variator is connected via an input connection (12) containing a ratio step with a shaft (14) which is operatively connected with one component (19) of said planetary gearing (18), wherein on said variator (5) is connected to input shaft (2) by a wet running multidisc clutch and in the range of higher forward traveling speed the input power is transmitted to said output shaft (17) via said planetary gearing (18) wherein in said planetary gearing (18) a division of power takes place and over said variator (5) an idle power circulates which is added to the input power in said main shaft (4) of said variator (5); wherein said variator (5) and said planetary gearing (18) are disposed coaxially horizontally and the exit of said variator is connected via a driving connection (12) with the shaft (14) which is operatively connected via transmission step (15, 16) with said one component (19) of said planetary gearing (18) and wherein a clutch (23) is inserted between said main shaft (4) of said variator (5) and an intermediate shaft (22), said intermediate shaft (22) being connected with said planetary gearing (18).
