The invention discloses a coaxial dual-motor driving assembly and a vehicle, and belongs to the technical field of vehicles. The invention discloses the coaxial dual-motor driving assembly and the vehicle. The coaxial dual-motor driving assembly comprises a box body, a dual-motor inverter and two motor driving structures, wherein the dual-motor inverter and the two motor driving structures are arranged in the box body; each motor driving structure comprises a driving motor and a speed reducing mechanism, the output end of the driving motor is connected with the input end of the speed reducing mechanism in an inserted mode, and the outer side of the inserted connection position of the output end of the driving motor and the input end of the speed reducing mechanism is sleeved with a supporting bearing. Or the motor driving structure is a magnetic gear. The dual-motor inverter and two motor driving structures are integrated in one box body, so that the height of the coaxial dual-motor driving assembly is reduced; the connection mode that the output end of the driving motor is connected with the input end of the speed reducing mechanism in an inserted mode can be adopted, only one supporting bearing is used for supporting the inserted connection position of the driving motor and the speed reducing mechanism, or a magnetic gear is adopted, and the axial size of the coaxial dual-motor driving assembly is reduced.
