A transmission comprises an input shaft and a variator having an infinitely variable transmission ratio. The variator has a variator input being driven by the input shaft and has a variator output. A planetary gear train is configured as a summing gear train with a first input, a second input and an output. The first input is adapted to be drivingly connected to the input shaft and the second input is driven by the variator output. An output shaft is driven by the planetary gear train output. A first clutch is provided for drivingly connecting the first planetary gear train input to the input shaft, whereas a second clutch is provided for drivingly connecting the variator output to the output shaft.

Transmission, in particular for agricultural vehicles and machines

The V-belt drive has a V-belt (R), revolving endlessly around a drive pulley (A) and at least one driven pulley (C) and a back chucking roller (D) is associated with the V-belt on the slack side (R1). The back chucking roller (D) is preceded in the belt travel direction (RL) by a profiled idler pulley (E), and both rollers (D, E) form a clamping unit (SE) that is subjected to clamping force action and acts near the driven pulley (C). In every position of the clamping unit (SE) the entry and exit point (G1 and G2, respectively) of the V-belt (R) at the profiled idler pulley (E) are located before, in the belt travel direction (RL), or at best coincide with the entry point (K1 and K2, respectively) of the back chucking roller (D).
