The two-gear large-speed-ratio electric drive axle transmission system comprises a first first-stage speed reduction driving gear, a second first-stage speed reduction driving gear, a second-stage speed reduction driving gear and a third-stage speed reduction driving gear, the first parallel shaft is provided with a first primary speed reduction driven gear and a first secondary speed reduction driving gear; the intermediate shaft is fixedly connected with a second-stage speed reduction driven gear, a first planet row and intermediate shaft joint teeth in sequence; the differential mechanism is connected with a first output half shaft, a second output half shaft and a connecting shaft; the second primary speed reduction driving gear is driven by a second motor; the second parallel shaft is provided with a second primary speed reduction driven gear and a second secondary speed reduction driving gear; and the synchronizer can be switched among a first position, a middle position and a second position. Power is transited to the intermediate shaft through the parallel shaft, so that the whole system is more flexible in arrangement, and the space can be fully utilized by adjusting the angles among the motor shaft, the parallel shaft and the intermediate shaft.

    提供了一种两挡大速比电驱桥传动系统,包括:第一一级减速主动齿轮,由第一电机驱动;第一平行轴,设置有第一一级减速被动齿轮和第一二级减速主动齿轮;中间轴,依次固定连接有二级减速被动齿轮、第一行星排和中间轴接合齿;差速器,连接有第一输出半轴、第二输出半轴和连接轴;第二一级减速主动齿轮,由第二电机驱动;第二平行轴,设置有第二一级减速被动齿轮和第二二级减速主动齿轮;和同步器,可在第一位置、中间位置和第二位置之间切换。动力通过平行轴过度到中间轴上,使得整个系统布置更灵活,通过调整电机轴、平行轴和中间轴之间的角度,能够充分利用空间。
