The invention provides a double-power-source electric drive assembly with a load balancing device, which can expand the torque range and the rotating speed range covered by output of the electric drive assembly, can also improve the control stability of an electric automobile and ensure the straight driving stability of the electric automobile. The double-power-source electric drive assembly comprises the load balancing device, so that the load torque difference transmitted to motors on the two sides by wheels can be reduced when the vehicle runs straightly, and wheel desynchrony caused by therotating speed difference of the motors on the two sides can also be reduced. When torque vector control is carried out on vehicle steering, the output torque difference of the motors on the two sides can be increased, the yawing couple torque is rapidly generated to prevent the sideslip phenomenon which is difficult to control, and the control stability of the vehicle is improved.

    本发明提出了一种具有负载均衡装置的双动力源电驱动总成,能够扩大电驱动总成输出覆盖的扭矩范围及转速范围,又可以提高电动汽车的操纵稳定性,并保证其直驶稳定性。本发明的双动力源电驱动总成,包含负载均衡装置,车辆直驶时可减小车轮传递至两侧电机的负载扭矩差,还可减轻由两侧电机转速差造成的车轮不同步;当车辆转向进行扭矩矢量控制时,可增大两侧电机输出扭矩差,快速产生横摆力偶矩防止出现难以控制的侧滑现象,提高车辆的操纵稳定性。
