The invention relates to a dual-motor automatic speed changing electric driving system and a speed changer, and belongs to the technical field of electric driving systems, the dual-motor automatic speed changing electric driving system comprises a first motor, a second motor and a system output shaft used for being in driving connection with a downstream system, and two rotor shafts of the first motor and two rotor shafts of the second motor are coaxially arranged; a rotor shaft of the first motor can penetrate through a rotor of the second motor and a rotor shaft of the second motor in a relatively free rotation mode, and the two rotor shafts and the system output shaft are arranged in parallel. And the two rotor shafts are connected with the system output shaft through a two-gear speed change structure. According to the electric driving system, the size is reduced through coaxial arrangement of the rotor shafts of the two motors and parallel arrangement of the two rotor shafts and the system output shaft, so that the structure of the electric driving system is compact; according to the electric driving system, two-gear variable speed control over the downstream system is achieved through the two-gear variable speed structure, and then the transmission structure of the electric driving system is simplified.
