MODULAR PLANETARY GEARBOX Russian patent published in 2007 - IPC F16H3/64 F16H15/56 

FIELD: mechanical engineering, possible use for building gearboxes primarily for automobiles mostly operating at lowered transmissions.

SUBSTANCE: gearbox contains three planetary modules, connected serially and made in accordance to one plan. Each module is a planetary heightening transmission with two solar central wheels engaged with two-crown satellites. Central wheels 1 and 2, 3 and 5, 5 and 6, in each module respectively are input and output link. Central wheel 1 of first module is connected to leading shaft 7 of gearbox, while output central wheel 6 is connected to driven shaft 8 of gearbox. Carriers 9, 10 and 11 of each module are provided with ribbon brakes 12, 13 and 14. Input and output links in each module are connected to each other by free drive sleeves 15,16,17 respectively. For realization of reverse drive first module is provided with central wheel 18 and blocking disk sleeve 19. Sleeve 19 connects either solar wheel 2 or crown wheel 18 of first module to input link 3 of second module. At output of gearbox, lowering transmission 26 is connected, 27 - engine, 28 - clutch.

EFFECT: simplified control system of gearbox, increased efficiency of gearbox at lowered transmissions.
