The invention discloses an electric all-terrain vehicle dual-motor drive assembly which comprises a front drive axle and a rear drive axle which are independently controlled, the front drive axle and the rear drive axle each comprise a motor, a gear transmission box, a differential mechanism and two half shafts which are sequentially in power connection, and the differential mechanism is arranged between the two half shafts; each differential mechanism is provided with a differential lock; and an output shaft of the motor is parallel to or vertically staggered with the half shaft. Compared with a single-transmission-box four-wheel-drive scheme, the four-wheel-drive four-wheel-drive system has the advantages that front and rear long transmission shafts are omitted, the space utilization rate of a whole vehicle is increased, and transmission efficiency loss of a front axle and a rear axle due to transmission axle coupling is reduced; through a control strategy, self-adaptive four-wheel-drive, escape, manual escape and other driving modes can be flexibly realized.

    本发明公开了一种电动全地形车双电机驱动总成,包括独立控制的前驱动桥和后驱动桥,所述前驱动桥和后驱动桥均包括依次动力连接的电机、齿轮传动箱、差速器以及两根半轴,差速器设置在两根所述半轴之间,所述差速器均配置有差速锁;所述电机的输出轴与所述半轴平行或垂直交错。本发明的有益效果是:两驱和四驱可通过控制策略实现转换,与单传动箱四驱方案相比,无前后长传动轴,提高了整车空间利用率,减少前后桥因传动桥耦合的传动效率损失,其前后独立的差速锁,通过控制策略可灵活实现自适应四驱及脱困、手动脱困等驾驶模式。
