The invention discloses a dual-motor parallel drive gearbox with a planetary reduction mechanism, which comprises a gearbox, a first input shaft, a first output shaft and a second input shaft are rotatably arranged in the gearbox in sequence, and the first input shaft, the first output shaft and the second input shaft are arranged and distributed in parallel; the transmission efficiency is higher than that of an existing single-motor technology, and three working modes can be derived through a precise control system regardless of same-side parallel connection or different-side parallel connection of double-motor driving, so that the whole machine can easily deal with complex working conditions, the system efficiency is effectively improved, the utilization rate of battery electric energy is improved, the charging frequency is reduced, and the cost is reduced. The endurance mileage of the whole machine is increased; according to the gearbox used in the dual-motor arrangement mode, a gear shifting mechanism is omitted, gear shifting is not needed, stepless speed change can be achieved from the zero speed to the highest speed, and the risks of impact jerking and power interruption generated in the gear shifting process are reduced; the system arrangement is simplified, and the reliability of the dual-motor driving unit is greatly improved.
本发明公开了一种带行星减速机构的双电机并联驱动变速箱,包括变速箱,所述变速箱内依次转动设置有第一输入轴、第一输出轴和第二输入轴,且第一输入轴、第一输出轴和第二输入轴相互平行排列分布,比现有单电机技术的传动效率要高,且双电机驱动无论同侧并联还是异侧并联,均可通过精密的控制系统衍生出三种工作模式,使整机可以轻松应对复杂的工况,有效的提高了系统效率,提高了电池电能的利用率,减少充电频率,增加了整机续航里程;双电机布置形式中使用的变速箱均减少了换挡机构,不用换挡,可从零速到最高速度实现无级变速,减少了换挡过程中产生的冲击顿挫,动力中断的风险;简化了系统布置,使双电机驱动单元的可靠性大大提高。
