Abstract

The invention belongs to the field of automobile motors, discloses an axial-axial magnetic field electromagnetic planetary gear power divider and aims to solve the problems of large size, complex structure, high cost, performance limitation and failure in effective power output of a system due to the fact that engines in existing series, parallel and series-parallel driving devices cannot simply and efficiently match with other parts of the system. A shell is partitioned into two portions in which an axial birotor motor and a radial torque adjustment motor are arranged. A flux adjustment rotor with q projection units in the axial birotor motor is driven by a prime motor, stators form a field with the pole number of 2p, and the required rotation speed is outputted by an output shaft of a permanent magnetic rotor with the pole number of 2n, wherein p is equal to |hn+kq|. The output rotation speed is independent from the input rotation speed to realize stepless speed change. The axial torque adjustment motor inputs driving torques or braking torques according to actual load demands to meet actual torque requirements of loads so as to balance input energy and output energy of output shafts of permanent magnetic rotors.

Description

technical field [0001] The invention relates to a power divider composed of motors with a composite structure, which belongs to the field of automobile motors. Background technique [0002] Fuel consumption and exhaust emission 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 batteries, which are one of the key components of electric vehicles, the cost performance of electric vehicles cannot compete with traditional internal combustion engine vehicles. Under such circumstances, hybrid electric vehicles, which combine the advantages of internal combustion engine vehicles and electric vehicles, develop rapidly and become a hot spot in the development of new vehicles. [0003] The characteristics of the existing serial driving device are: the engine can be operated stably in its best worki...
