ABSTRACT:
A synchronized mechanical-hydrostatic gearbox with infinitely variable drive ratio including a hydrostatic gear and a following mechanical gear coupled thereto. The hydrostatic gear includes a hydraulic transmission motor with variable displacement which is connected to the mechanical gear. The mechanical gear is made with at least two gear ratio stages and with means adapted for altering the displacement of the hydraulic transmission motor on alteration of the gear ratio of the mechanical gear to an extent corresponding to the gear ratio change. The gear box is intended to be incorporated in a transmission for vehicles, particularly terrain vehicles, preferably driven by an internal combustion engine.
