Abstract

A transmission system suitable for operation with a drive machine includes an input shaft for a drive power, at least one output shaft for outputting drive power, a power-split transmission section having at least one variable transmission branch and a mechanical transmission branch, a manual transmission, a transmission system controller, and at least one first and second electric machine for generator and motor operation. The electric machines are electrically connected to one another. The drive power is divided up and conducted by the mechanical and variable transmission branch. An input-coupled, magnetically electric epicyclic gear stage brings together the variable transmission branch and mechanical transmission branch, and is activated by the second electric machine such that the output shaft of the transmission system rotates counter to a direction of rotation at the input shaft to provide a forward and reverse operation of the transmission system.
