GEARBOX WITH TWO-ROW PLANETARY AUXILIARY GEARBOX Russian patent published in 2020 - IPC F16H3/93 

FIELD: transport machine building.

SUBSTANCE: invention relates to transmissions of off-road vehicles. Gearbox with two-row planetary low-multiplier comprises housing, in which primary shaft, intermediate shafts with gears fixed on them, secondary shaft located coaxially with the primary shaft, gears located on the primary and secondary shafts and engaged with the countershaft gears, reversing transmission gear engaged with intermediate gears engaged with countershaft gears, couplings for gears with shafts connection. Double-row planetary splitter consists of two three-link planetary rows, sun gear of the first planetary row is connected to secondary shaft of gearbox, carrier of said planetary row is connected to sun gear of second planetary row, carrier of second planetary row is connected to output shaft, demultiplier comprises coupling for alternate coupling of crown planetary gear of first planetary row with housing and carrier of said planetary row, a coupling for alternate coupling of crown gear of the second planetary row to the housing and to any carrier of the multiplier.

EFFECT: improved operational characteristics of gearbox, simplified design and reduced metal consumption.
