A hybrid drive is proposed for traction wheels of a vehicle, which drive comprises a mechanical power source with a shaft, a planetary mechanism having a sun and a ring gear wheels, and two reversible electrical machines connected to an electrical power source via a control system. A carrier of the planetary mechanism is coupled to the shaft. With the view to increasing the traction wheels' torque, one of the electrical machines is designed as a two-dimensional machine with two rotatable members, one of which members is coupled to the sun gear wheel, the second member is coupled to the ring gear wheel. For increasing the performance characteristics, the drive is provided with two controllable clutches, which make it possible to interconnect the rotatable members and to couple the carrier to an immovable portion of the drive or vehicle. Operation of the drive in various motion modes is also described.
