The invention relates to a differential mechanism with double internal meshing planet rows and a transmission system, belongs to the technical field of vehicle transmission, and solves the problems that a vehicle differential mechanism in the prior art is large in size and difficult to machine. The double-inner-meshing planetary gear train comprises a first output shaft (1), a second output shaft (2) and a double-inner-meshing planetary gear train (3), the double-inner-meshing planetary gear train (3) comprises a gear ring (31) with input teeth, a planetary gear (32) with first inner teeth (321) and first outer teeth (322), a frame (34) and a sun gear (33), the planetary gear (32) is arranged on the frame (34), the planetary gear (32) is internally meshed with the sun gear (33), and the planetary gear (32) is internally meshed with the gear ring (31); power is input through input teeth of the gear ring (31); the first output shaft (1) is connected with the frame (34); and the second output shaft (2) is connected with a sun gear (33). The differential mechanism overcomes the defects that a symmetrical bevel gear differential mechanism is difficult to machine, large in axial size, high in cost, large in axial force during working and the like, the number of parts is reduced, and the size and the weight of the differential mechanism are reduced.
