Abstract
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.

A transmission comprising:
- a) an input shaft;
- b) a variator having an infinitely variable transmission ratio, said variator having a variator input being driven by said input shaft and having a variator output;
- c) a planetary gear train being configured as a summing gear train with a first input, a second input and an output, said first input being adapted to be drivingly connected to said input shaft and said second input being driven by said variator output, wherein said planetary gear train is an epicyclic gear train and includes two gearwheel pairs having each a first and a second gearwheel meshing with each other, said first gearwheels being rigidly mounted on a common arm shaft whereas one of said second gearwheels is connected to said first planetary gear train input for common rotation therewith, and the other of said second gearwheels is connected to said planetary gear train output for common rotation therewith, said arm shaft being rotatably journaled in an arm housing, said arm housing being connected to a hollow shaft constituting said second planetary gear train input;
- d) an output shaft driven by said planetary gear train output;
- e) a first clutch for drivingly connecting said first planetary gear train input to said input shaft;
