Abstract: A power split transmission structure has at least three interfaces to direct driving power from a drive to at least one output in order to supply the driving power to connected consumers. It comprises at least two variator paths which each comprise a summation gearbox communicating with an electric or hydraulic machine via a mechanical and a non-mechanical path in order to modify torque, speed or both of the driving power.

The transmission structure directs the driving power via the variator paths such that the electric or hydraulic machine of each variator path is operable in a generator or motor mode in order to compensate for a power shortfall or a power oversupply at at least one outlet of the transmission structure.
