METHOD OF AUTOMATIC STALLING OF VEHICLE DRIVE WHEEL AND STEERING MECHANISM REINFORCEMENT DURING MANOEUVRING IN MANUAL CONTROL MODE, PROVIDING VEHICLE TURN IN LIMITED TERRITORY, HAVING AC ELECTRIC DIFFERENTIAL ELECTRIC DRIVE SYSTEM, AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2020 - IPC H02P1/30 H02P25/18 B60L15/10 

FIELD: machine building.

SUBSTANCE: invention relates to the field of transport, in particular, to electric differentials of alternating current with pulse-frequency control. Complex mechanical interlocking devices are installed in vehicle transmission with mechanical differential of drive axle for stalling of wheels slippage. To disrupt this mode in the Electric differential system, there proposed is a method and a device for its implementation without using said means - by reducing the driving moment in the drive of the slipping wheel drive due to short-circuiting of two phase stator windings in pulse-frequency mode through braking resistors by means of triac keys controlled both in Manual mode - by limit switches installed in rudder mechanism, and automatically by means of time relay, coil of which is connected through voltage cut resistor to output of rectifying bridge, diagonal of which is connected to switched phase winding of drive motor. Electric drive comprises two identical sets of equipment of left and right drive wheels, besides, electric diagram allows, apart from slippage, also to strengthen steering mechanism in Manual mode of control at vehicle manoeuvring, including during turn on place.

EFFECT: technical result is creation of electric differential of alternating current with pulse-frequency control to disrupt the slippage mode of drive wheel and reinforcement of rudder mechanism.
