A drive system for commercial vehicles, especially agricultural or industrial tractors, is described. The system contains a generator driven by an IC engine (16) and at least one driven axle(34). The two wheels (14) on this axle are driven by an electric motor fed from the generator. To attain a good overall efficiency, a continuous matching of the speeds and/or torques of the individual wheels to the travel requirements and to improve the travel properties, a hybrid drive is proposed whereby the IC engine drives at least one shaft (28) connected to the driven axle. On each wheel of this axle is a summing gearbox combining the outputs of the shaft and the electric motor before passing this to the wheel |
