The electric drive axle transmission structure with the three forward gears comprises a first-stage speed reduction driving gear, a second-stage speed reduction driving gear, a third-stage speed reduction driving gear and a fourth-stage speed reduction driving gear, a first shift unit; the intermediate shaft is fixedly connected with an A-gear driven gear, a B-gear driven gear and a planet row, and the A-gear driven gear is used for receiving power of the A-gear driving gear; the first short shaft is arranged outside the first power output half shaft in a relatively rotating and sleeving manner and is fixedly connected with a second adapter gear, and the second adapter gear is meshed with the first adapter gear; a second shift unit; the C-gear driven gear is fixedly connected to a planet carrier of the planet row and used for receiving power of the C-gear driving gear; the differential mechanism is connected to a planet carrier of the planet row through a differential mechanism shell and outputs power to the first power output half shaft and the second power output half shaft. And the high-efficiency requirements of low-gear high torque, high-gear high speed and common working conditions can be met.

    提供了一种具有三个前进挡的电驱桥传动结构,包括:一级减速主动齿轮,用于接收电机的动力;第一换挡单元;中间轴,固定连接有A挡被动齿轮、B挡被动齿轮和行星排,A挡被动齿轮用于接收A挡主动齿轮的动力;第一短轴,可相对转动地套设于第一动力输出半轴外,且固定连接有第二转接齿轮,第二转接齿轮与第一转接齿轮啮合;第二换挡单元;C挡被动齿轮,固定连接于行星排的行星架且用于接收C挡主动齿轮的动力;以及差速器,通过差速器壳体连接于行星排的行星架,并将动力输出至第一动力输出半轴和第二动力输出半轴。可满足低挡高扭,高挡高速以及常用工况的高效率需求。
