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.
