Abstract
A hydro-mechanical power transmission for vehicles wherein optional two of the three elements of a planetary gearing serve as an input portion and an output portion, and the other element is driven at a steplessly variable speed by a static hydraulic speed change device which is operable by the input portion or the output portion. A change-over device is provided in a power transmission system for the speed change device to drive the other element in different speed ranges by switching the change-over device. For running on the road, the speed is widely variable from low to high, while for working, the running speed is finely adjustable within one of the speed ranges.
