The invention relates to a multi-gear transmission electric drive axle system which is suitable for a pure electric drive heavy commercial truck, and compared with the prior art, the multi-gear transmission electric drive axle system can achieve gear shifting without power interruption and is simple in structure, power control is convenient, gear shifting is convenient to increase and decrease through modular design, and under the condition that double motors are symmetrically arranged, the electric drive axle system can be widely applied to the field of electric vehicles. The low-gear large-torque requirement and the high-gear high-speed requirement can be considered at the same time, and meanwhile it is guaranteed that the two motors are both in the optimal efficiency rotating speed interval. Half of the motor and one set of gear shifting mechanism can be reserved to serve as a single-motor three-gear electric drive system to be matched with suitable vehicle types, and the research and development period is greatly shortened.
本发明涉及一种多挡传动电驱桥系统,适用于纯电驱动的重型商用卡车,与现有技术相比,本发明的电驱桥系统能够实现换挡无动力中断,且构型简单,动力控制方便,模块化设计增减挡位方便,在对称布置双电机的情况下,可同时兼顾低挡位大扭矩需求及高挡位高速需求同时保证两个电机均在最佳效率转速区间。本发明亦可进保留一半电机及一套换挡机构,以作为单电机三挡电驱系统匹配适用车型,大大减小研发周期。
