WIDE-RANGE CONTINUOUSLY RATED DRIVE (SUPER VARIATOR) Russian patent published in 2011 - IPC F16H15/52 

FIELD: machine building.

SUBSTANCE: wide range continuously rated drive consists of stepless transmission (1) with interconnected reversible electro- and hydraulic machines. The stepless transmission is kinematically connected with differential (4) and matching (5) transmissions. Transmission ratios of tooth pairs formed with kinematic link of the differential and matching transmissions are made such, as to facilitate matching in direction and by rotation frequency at maximal and minimal transmission ratios of the stepless transmission rotation of any two tooth gears freely sitting on shaft (20) and entering into periodic simultaneous connection with this shaft. An output link of the stepless transmission has periodic connection with shaft (20) of matching transmission (5) through a reverse mechanism. Input shafts of the stepless transmission and whole super variator have periodic kinematic connection with shaft (20) of the matching transmission when links of differential mechanisms of the differential transmission are disconnected from it.

EFFECT: simplified control of super variator, its raised efficiency and reduced installation power and weight of reversible machines.
