The invention provides a mine truck electric drive axle which comprises a first motor, a second motor, a first intermediate shaft, a third motor, a fourth motor, a second intermediate shaft and a differential mechanism, a plurality of first clutch sets are arranged on the first intermediate shaft, and the first clutch sets can be selectively connected with gears of first gear pairs on the two sides; a plurality of second clutch sets are arranged on the second intermediate shaft and can be selectively connected with gears of the second gear pairs on the two sides. Four motors are adopted for driving, so that high power can be provided; a double-intermediate-shaft structure is adopted, four gears are arranged on each intermediate shaft, and the intermediate shafts on the two sides can achieve alternate gear shifting, so that combined gear shifting of at least seven gears is achieved, the speed ratio range is wide, the output torque is large, and the power requirement of a large-tonnage mine truck can be met; the intermediate shafts on the two sides alternately shift gears, power-interruption-free gear shifting can be achieved, and the gear shifting power requirements of large-tonnage and super-tonnage mine trucks are effectively met.
本发明提供一种矿卡电驱桥,包括:第一电机和第二电机,第一中间轴,第三电机和第四电机,第二中间轴,差速器,在第一中间轴上分别设置有若干第一离合器组,第一离合器组能够与两侧第一齿轮副的齿轮选择性地接合;在第二中间轴上分别设置有若干第二离合器组,第二离合器组能够与两侧第二齿轮副的齿轮选择性地接合;采用四电机驱动,可提供功率大;采用双中间轴结构,每个中间轴上布置有四个挡位,两侧的中间轴可以实现交替换挡,从而实现至少七个挡位的组合换挡,速比范围较宽,输出扭矩较大,可以满足大吨位矿卡的动力需求;两侧的中间轴交替换挡,可以实现无动力中断换挡,有效适配于大吨位和超大吨位矿卡的换挡动力需求。
