The invention relates to a multi-integrated two-gear non-independent suspension electric drive axle which comprises a control unit, a drive unit and a gearbox. The control unit comprises a motor controller and a gear shifting controller; the driving unit comprises a driving motor and a gear shifting motor, and the driving motor is connected with an input shaft of the gearbox through a spline; the gear shifting motor is arranged on the outer side of a gear shifting executing mechanism of the gearbox and is in rigid connection with the gear shifting executing mechanism through a bolt. The gearbox is a two-gear gearbox and comprises a two-gear variable-speed transmission mechanism, a gearbox shell and a differential mechanism assembly. An output gear of the two-gear variable-speed transmission mechanism is connected with the differential mechanism assembly through a bolt; the problems that in the prior art, a motor, a motor controller, a gearbox and an axle are arranged separately, a transmission chain is long, efficiency is low, arrangement is difficult, the integration degree of a motor and speed reducer integrated arrangement scheme is low, and higher requirements of terminal clients for dynamic property, economical efficiency and arrangement space cannot be met are solved.

    本发明涉及一种多集成两挡非独立悬架电驱动桥,包括控制单元、驱动单元、变速箱;所述控制单元包含电机控制器和换挡控制器;所述驱动单元包含驱动电机和换挡电机,所述驱动电机通过花键与所述变速箱输入轴连接;所述换挡电机设置于所述变速箱的换挡执行机构外侧,所述换挡电机通过螺栓与所述换挡执行机构刚性连接;所述变速箱为两挡变速箱,包含两挡变速传动机构、变速箱壳体以及差速器总成;所述两挡变速传动机构的输出齿轮与差速器总成通过螺栓连接;解决了现有技术电机、电机控制器、变速箱、车桥分开布置传动链长,效率低,布置困难,电机与减速器集成布置方案集成度低,无法满足终端客户对动力性、经济性以及布置空间的更高要求的问题。
