The invention relates to the technical field of planetary gear set transmission, and discloses a coaxial transmission device, a power system and a vehicle, the coaxial transmission device comprises a shell assembly, a planet carrier assembly, a sun wheel assembly, a planet wheel assembly and a differential mechanism assembly, and an inner gear ring part is arranged in the shell assembly; the planet carrier assembly is rotationally arranged in the shell assembly around the axis of the planet carrier assembly, and a driving cavity and an output cavity are formed in the planet carrier assembly in the axial direction of the planet carrier assembly. The sun gear assembly is rotationally arranged in the driving cavity around the axis of the sun gear assembly and is in transmission connection with a rotating shaft of the rotating driving device; the multiple planet wheel assemblies are evenly distributed in the circumferential direction of the planet carrier assembly, and the two ends of a rotating shaft of each planet wheel assembly are connected with the planet carrier assembly. The differential assembly is rotationally arranged in the output cavity around the output axis of the differential assembly, and a planetary gear component of the differential assembly is fixedly connected with the planetary carrier assembly; the problems that a coaxial transmission device is poor in dynamic balance performance and poor in NVH performance can be solved.
