Abstract: The variable-speed power transmission device comprises an input gearing for dividing the power into two fractions having different and variable speeds. The first of these two fractions is transmitted directly to an output gearing, while the second is transmitted to a hydrostatic pump-motor assembly which varies its speed and then to the above mentioned output gearing which recombines it with the first fraction.
