A hybrid gearbox for land vehicles and automotive machines is designed such that the starting up and maneuvering operations of the vehicles are powered by a hydromotor and their normal travel is powered by a direct coupling with an internal combustion engine. In its normal operation, the internal combustion engine drives a neutrally positioned axial piston pump as well as the driven shaft. When operated under load, the driven shaft is decoupled from the internal combustion engine, and the latter drives the variable axial piston pump which in turn delivers pressure to the hydromotor. |
