The invention provides a multi-gear electric drive transmission system. The system comprises a shaft I, a shaft II, a shaft III (8) and a shaft IV (26) which are arranged in parallel, and a left half shaft (25) and a right half shaft (1) are concentrically arranged with the shaft III; the motor and the gearbox are integrated, and the space is compact; the shaft III and the differential mechanism are concentrically designed, a power transmission path returns to the shaft III from the shaft IV, and offset is reduced; the shaft III and the left half shaft adopt a shaft sleeve shaft design, and the left half shaft penetrates through the shaft III for output; one gear shifting executing mechanism controls three clutches; and the gears are mechanically interlocked through rotation of the gear shifting drum and sequential gear shifting, so that the safety is improved, and the control difficulty is reduced.
本发明提供一种多挡电驱动传动系统,包括相互平行设置的Ⅰ轴、Ⅱ轴、Ⅲ轴(8)、及Ⅳ轴(26),所述左半轴(25)和所述右半轴(1)与所述Ⅲ轴同心设置;电机与变速箱集成设计,空间紧凑;Ⅲ轴与差速器同心设计,动力传递路径由Ⅳ轴返回Ⅲ轴,减小偏置;Ⅲ轴与左半轴采用轴套轴设计,左半轴穿过Ⅲ轴输出;一个换挡执行机构控制3个离合器;各档位通过换挡鼓旋转,次序换挡,实现档位机械互锁,提高了安全性,降低了控制难度。
