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 and variable-speed gear (1). Output link (11) and input shaft (2) of variable-speed gear (1) combined with input shaft of supervariator are kinematically connected with differential mechanism of variable-speed gear, as well as with differential gear (3). Output link (11) is alternatively connected with differential mechanisms (5, 6) of differential gear (3) by means of moving unit (18) with gear wheels on it. The gear wheel (20) is periodically connected with additional planetary gear (24) acting as neutral, reverser and interlock. Elements of differential gear (3) are kinematically connected with gear pairs (40), (38) and (36) transferring rotation to output shaft (35) f matching gear (4) and the whole drive - supervariator.

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