DIFFERENTIAL DRIVE Russian patent published in 2015 - IPC F16H3/72 

FIELD: machine building.

SUBSTANCE: group of inventions relates to the differential drives, and can be used in all industries where there is need in stepless changed torques and speed of rotation of the output shafts. The differential drive contains two motors, drive control system, casing, installed in casing two pinions with outside teeth engaging with each other, central wheel with internal teeth, and pinion with outside teeth installed on the output shaft engaging with the outside teeth of the satellite gears installed using the axles on the pinion carrier connected with the first motor. As per the first option the central wheel with the internal teeth via the pinion with outside teeth connected with it, engages with the other pinion with outside teeth installed on the parallel shaft of the second motor. As per the second option the central wheel with the internal teeth is connected with the output shaft.

EFFECT: stepless change of the speed of rotation of the output shaft, and increased range of rotation frequency of the output shaft of the differential gear.
