The invention provides a double-motor multi-mode rotation speed coupling driving assembly. According to the double-motor multi-mode rotation speed coupling driving assembly, overrun clutches achieve mode switching; a single planetary row system composed of a planetary gear mechanism 9 serves as the power coupling device of a first motor 18 and a second motor 12; a first bidirectionally controllable overrun clutch 9 and a second bidirectionally controllable overrun clutch 14 are used for limiting the rotation of the first motor 18 and the second motor 12 respectively and further achieving multiple working modes of a vehicle under advancing and backing conditions as well as non-impact switch of the working modes. The double-motor multi-mode rotation speed coupling driving assembly can achieve the multiple working modes double-motor single driving, double-motor rotation speed coupling driving, double-motor single brake energy recovery and double-motor rotation speed coupling driving energy recovery, meet the dynamic requirements of vehicle travelling and avoid impact during mode switching, and meanwhile, is low in requirements on motor torque control precision and high in efficiency of a transmission system.
