The invention relates to an electric driving system and a transmission for a pure electric loader, and belongs to the technical field of new energy electric driving systems, the electric driving system specifically comprises a driving motor and a system output shaft used for being in driving connection with a downstream system, and a rotor shaft of the driving motor and the system output shaft are coaxially arranged; the system output shaft can penetrate through the rotor and the rotor shaft in a relatively free rotation mode, and a gear shifting speed changing structure is arranged between the rotor shaft and the system output shaft. According to the electric driving system and the transmission for the pure electric loader, the rotor shaft and the output shaft of the driving motor are coaxially arranged, so that transmission stages used for connecting the distance between the rotor shaft and the output shaft in the transmission stages of the gear shifting and speed changing structure are further reduced, and then the total transmission stage number of the electric driving system is reduced; the transmission efficiency of the electric driving system is improved, and the purposes of body and weight reduction and cost reduction are achieved.

    本发明涉及一种用于纯电动装载机的电驱动系统和变速器,属于新能源电驱动系统技术领域,具体包括驱动电机和用于与下游系统驱动连接的系统输出轴,驱动电机的转子轴和系统输出轴同轴布置,系统输出轴可相对自由转动地贯穿转子和转子轴设置,转子轴和系统输出轴之间设置有换挡变速结构。本发明的一种用于纯电动装载机的电驱动系统和变速器通过将驱动电机的转子轴和输出轴同轴布置,使得换挡变速结构的传动级数中用于衔接转子轴和输出轴之间距离的传动级进一步减少使用,进而减少该电驱动系统的总传动级数,提高电驱动系统的传动效率,实现减体减重降本的目的。
