Abstract
Driving system for a an industrial truck with a combustion engine, a two-branch gear transmission whose first shaft is coupled to the combustion engine, whose second shaft is coupled to a change-over transmission, whose outlet acts on the driven wheels of the industrial truck via a collecting transmission, an electric transmission of which a first electric machine cooperates therewith, with respect to the torque, using the two-branch gear transmission, and a second electric machine is coupled via at least one collecting transmission to the driven wheels, the two-branch gear transmission producing a constant torque ratio between the first electric machine and at least the first and second shaft and an electrical circuit arrangement electrically coupling the electric machines and being connected to an electric accumulator,
