Abstract

An axial-radial magnetic field electromagnetic planetary gear power divider belongs to the field of automobile motors, and aims to solve the problem that in a conventional tandem-type / parallel-type / series-parallel driving device, the engine cannot simply and efficiently cooperate with other parts of a system, so that the system is large in size, complex in structure and restricted in performance and cannot output power effectively. The power divider is characterized in that a casing is divided into two parts which are provided with an axial double-rotor motor and an axial radial torque regulation motor; a magnetic flux regulating rotor with q protrusion units and in the axial double-rotor motor is driven by a primary machine, and a stator forms a 2p pole field, the required rotate speed is output by an output shaft of a p-m rotor with 2n poles, wherein, the relation expression that p equals to the absolute value of hn and kq is met, besides, the output rotate speed does not depend on the input rotate speed, so that infinitely variable speed can be realized; the torque regulation motor inputs driving torque or retarding torque according to the requirement of practical load to meet the requirement on practical torque of the load, so that the input energy and the output energy of the output shaft of the p-m rotor are balanced.

Description

Technical field [0001] The invention relates to a composite structure motor, belonging to the field of motors. Background technique [0002] The fuel consumption and exhaust pollution of traditional internal combustion engine vehicles are hot issues of worldwide concern. The use of electric vehicles can achieve low energy consumption and low emissions. However, due to the energy density, lifespan, and price of the battery, which is one of the key components of electric vehicles, the cost-effectiveness of electric vehicles cannot compete with traditional internal combustion engine vehicles. In this case, hybrid electric vehicles that integrate the advantages of internal combustion engine vehicles and electric vehicles have developed rapidly and have become a hot spot in the development of new vehicles. [0003] The characteristics of the existing tandem drive device are: the engine is not affected by the driving conditions of the car, and it always runs stably in its best working a...
