FIELD: transport.SUBSTANCE: invention relates to drives of transport facilities. In compliance with first and second versions, proposed drive comprises ICE, motor, first input shaft, second input shaft, output/input shaft, first, second and third gears. Said shaft, first, second and output/input shafts are arranged parallel with ICE output shaft. Output/input shaft transfers power to driven part. First set of gears is fitted on first input shaft. Second set of gears is fitted on second input shaft. Third set of gears is fitted on third input shaft. In compliance with first version, with electric vehicle deceleration at step-down gearing braking force is applied at actuation of wheel brakes while motor performs recuperation. In compliance with second version, with electric vehicle deceleration at step-down gearing braking force results from braking by engine. Note here that at step-down shifting from high gear of the first set to low gear of said set, ICE is started and one gear of second set is selected by second shifting unit while recuperation is effected by motor.EFFECT: efficient use of recuperation by motor.8 cl, 19 dwg |
