DRIVE MECHANISM WITH THE GEAR SHIFT Russian patent published in 2018 - IPC G06G3/02 B66D1/24 F16H48/00 

FIELD: machine building.

SUBSTANCE: invention relates to the mechanical transmissions in lifting winches and off-road vehicles drives. Drive mechanism with gearshift contains summing differential (1), which output (2) is connected to the actuator. Differential (1) input (4) is equipped with brake (10), blocking the reactive torque transfer from the load. Differential (1) inputs (3, 4) are kinematically connected to two drive motors (21, 22) shafts via the distributing unit (5). Unit (5) distributes the kinematically connected to its inputs (8, 9) drive motors (21, 22) total power between its outputs (6, 7). Unit (5) is made in the form of summation differentials (11, 12), which outputs serve as unit 5 outputs. Each of four differential inputs (11, 12) is kinematically connected to unit (5) one of the inputs. One of the four gear ratios from unit (5) each input (8, 9) to each of its output (6, 7) is opposite in sign to the three other gear ratios.

EFFECT: enabling increase in the engines installed power using efficiency in the drive mechanism with a gear change.
