FIELD: machine building.
SUBSTANCE: drive mechanism for transfer of torque to the first and the second driven elements includes a drive and a switching element connected to the drive. The switching element is connected selectively to the first driven element in a vector mode or to a fixed case-shaped part in a traction mode. The switching element is connected to the first driven element by means of a connection element. When in traction mode, torque of the drive is transferred to the first and the second driven elements in one and the same directions, and when in a vector mode, in opposite directions. The first and the second driven elements and the drive are connected with a differential gear containing a gear wheel with external teeth, which is connected to the second drive element. The first driven element is connected to a carrier of planetary differential gear, and the second driven element is connected to a solar gear of the planetary differential gear.
EFFECT: improving torque transfer efficiency and simplifying the design.
