FIELD: machine building. ^ SUBSTANCE: wide range continuously rated drive consists of stepless transmission (1) with interconnected reversible electro- and hydraulic machines. Output link (11) and input shaft (2) of stepless transmission (1) combined with input shaft of the super variator are kinematically connected with the differential mechanism of stepless transmission, and also with differential transmission (3). Output link (11) is connected with differential mechanisms (5, 6) of differential transmission (3) alternately by means of movable unit (18) with tooth gears on it. Tooth gear (20) is periodically connected with additional planetary transmission (24) corresponding to neutral, reverse and blocking. Elements of differential transmission (3) are kinematically coupled with tooth pairs (40), (38) and (36) transferring rotation to output shaft (35) of matching transmission (4) and total drive-super variator. ^ EFFECT: simplified control of super variator, its raised efficiency and reduced installation power and weight of reversible machines. ^ 6 cl, 5 dwg |
