ELECTRIC DRIVE FOR AUTOMOBILE VEHICLE Russian patent published in 2017 - IPC B60K1/00 F16H37/08 F16H48/36 

FIELD: transportation.

SUBSTANCE: electric drive comprises the first two gear wheels engaged with the second gear wheels mounted on the intermediate shaft parallel to the output shaft. For implementation of the two-speed shift, a freewheel with a mechanical stop or clutch is connected with the corresponding pair of gear wheels formed from the first gear wheel and the second gear wheel. Coaxial with respect to the intermediate shaft are two planetary gear mechanisms that can be driven by an intermediate shaft. The drive of the corresponding planetary gear mechanism is carried out by means of the sun gear wheel of the planetary gear mechanism, and the power output of the corresponding planetary gear mechanism to the shaft axis associated with said planetary gear mechanism is effected by the planetary gear carrier of the planetary gear mechanism. To realise the differential function, the gear wheels of the planetary gear mechanisms are provided with tooth systems with external gearing, the annular gear wheels of the planetary gear mechanisms being engaged by these tooth systems with external engagement.

EFFECT: increased efficiency of the electric drive.
