STEPLESS GEARBOX (VERSIONS) Russian patent published in 2012 - IPC F16H37/08 F16H15/50 

FIELD: transport.

SUBSTANCE: proposed gearbox comprises housing 3, input and output shafts 1, 2, variator link 4, kinematic links coupling variator link 4 with differential and matching trains 14, 15. Input element 13 of variator 4 makes input link of gearbox and differential gearbox 14 consisting of two differential mechanisms of forward and reverse modes. Matching gearing 15 is composed of three shafts with, at least, one idle shaft, running in bearings in housing 3 to engage with output links of differential transmission output licks and matching transmission output shaft. In first version, output element 15 of variator link doubles as input element of matching transmission in its first range. In compliance with second version, only output links 16, 17 of differential gearing 14 is introduced in matching transmission.

EFFECT: higher efficiency of gearbox, expanded of gear ratios.
