The invention relates to an integrated multi-gear variable-speed electric drive axle assembly which comprises a speed reducer assembly, a motor assembly and an electric control unit. The speed reducer assembly is connected with a motor assembly, and the motor assembly is controlled by an electric control unit; according to the invention, the worm and gear mechanism is controlled through the sequence gear shifting execution motor, simultaneous action of the main speed change mechanism and the auxiliary speed change mechanism is realized, and the gear shifting stroke and the gear shifting time are effectively reduced, so that the gear shifting time interval is effectively improved, and the gear shifting efficiency is obviously improved.

    本发明涉及一种集成式多挡变速电驱动车桥总成,包括减速器总成、电机总成、电控单元;所述减速器总成与电机总成相连接,所述电机总成由电控单元控制;本发明通过序列换挡执行电机控制蜗轮蜗杆机构,实现主/副变速机构的同时动作,有效减小换挡行程及换挡时间,从而有效提升了换挡时间间隔,换挡效率得到明显提升。
