Abstract
A vehicle with a drive engine, with at least two vehicle axles and a transmission unit for variable distribution of drive torque from the drive engine in the vehicle's longitudinal direction between the vehicle's axles. The transmission unit is made with an input shaft and at least two output shafts, at least two planetary gearsets and an electric machine arranged between two mutually connected shafts of the planetary gearsets for distribution of the torque delivered via the transmission input shaft between the transmission output shafts as a function of a torque produced by the electric machine. The electric machine is in active connection with the transmission unit connecting between the two interconnected shafts of the planetary gearsets and the planetary gearsets are made with different transmission ratios so that the electric machine is driven by virtue of a speed difference between the actively interconnected shafts of the planetary gearsets.
