Novel electromobile electric drive axle system

Abstract

The invention discloses a novel electromobile electric drive axle system. The novel electromobile electric drive axle system comprises a middle double-rotor motor, a left side transmission mechanism, a left drive wheel, a first auxiliary drive mechanism, a right side transmission mechanism, a right drive wheel and a second auxiliary drive mechanism, two output shafts of the middle double-rotor motor are respectively in transmission connection with the left side transmission mechanism and the right side transmission mechanism, the left side transmission mechanism is in transmission connection with the left drive wheel, the right side transmission mechanism is in transmission connection with the right drive wheel, the first auxiliary drive mechanism and the second auxiliary drive mechanism are respectively in separation and reunion transmission connection with the left side transmission mechanism and the right side transmission mechanism. The novel electromobile electric drive axle system not only effectively forms an efficient electric drive system for an electromobile, but also realizes the functions of joint drive, energy recovery, stationary power generation and electronic differential according to the practical requirements, therefore, a driving torque of the electromobile is effectively supplied, the kinetic energy of the motor is also maximally utilized, the energy is saved, the waste of the kinetic energy of the motor is reduced, and the cost is saved.
