ELECTRIC AUTOMOBILE FURNISHED WITH MULTIPLE DRIVE MOTORS

摘要

The present invention relates to an electric automobile furnished with multiple drive motors and more specifically to an electric automobile furnished with multiple drive motors, wherein torque output from at least two drive motors are combined into one torque using differential equipment and sent as output so that a small drive motor may be used to obtain high output. For small loads such as driving on flat ground, a part of the drive motor is operated, while for larger loads such as driving on a slope or rough road which results in slower speed, the remaining drive motor is operated and combined with differential equipment so that the output required for driving the vehicle may be generated depending on load fluctuations and the drive motor may be controlled dependent on load fluctuations, which enable minimization of the consumption of charged power. The electric automobile with the multiple drive motors of the present invention is furnished with a first drive motor that generates a torque for output to a first input shaft, a second drive motor that generates a torque for output it to a second input shaft, and drive equipment including a differential combination part that receives the torque of said first input shaft and the torque of the second input shaft as input and outputs the torque to a single output shaft.
