WIDE-RANGE CONTINUOUSLY VARIABLE-RATIO DRIVE (SUPERVARIATOR) Russian patent published in 2014 - IPC F16H15/52 

FIELD: transport.

SUBSTANCE: invention relates to transport machine building and can be used as continuously variable transmission of automotive and continuously variable driveline of hybrid power trains with flywheel energy accumulators. The wide-range continuously variable-ratio drive includes variable-speed gear (1) with interconnected reversible electric and hydraulic machines. The variable-speed gear is connected with differential (4) and matching (5) gears. Gear ratios of gear pairs formed by kinematical connection of differential and matching gears are made so that when gear ratios of variable-speed gear are maximal and minimal the rotation of any two gear wheels being loose on the shaft (20) and periodically engaging with this shaft could match in direction and rotation frequency. Output link of the variable-speed gear has periodical connection with shaft (20) of matching gear (5) via reversing mechanism. The input shafts of variable-speed gear and entire supervariator have periodical kinematical connection with the shaft (20) of matching gear when differential gear differential mechanisms links are disconnected from it.

EFFECT: invention permits to simplify supervariator control, as well as to increase its coefficient of efficiency and decrease installed power and weight of reversible machines.
