AUTOMATIC HYDRAULIC VARIATOR WITH STEPWISE VARIABLE VOLUMETRIC COMPONENT Russian patent published in 2024 - IPC F16H39/00 B60K17/10 

FIELD: hydraulics.

SUBSTANCE: device relates to reversible hydraulic motors with stepwise variable volumetric component. Variator includes N number of cells, connected to high-pressure and low-pressure pipelines of the working fluid and consisting of a hydraulic motor with a built-in reversible overrunning clutch, controlled by hydraulic cylinders, which are connected through pressure reducing valves and valves to high-pressure and low-pressure pipelines of working fluid. Hydraulic motors of each cell are assembled on a single shaft. Cell pressure reducing valves are set to successive increase of working fluid pressure, it is possible to swap high-pressure and low-pressure pipelines of working fluid.

EFFECT: providing the possibility of smooth increase of climb and reduction of movement speed.
