Differential mechanism and vehicle

The utility model provides a differential mechanism and a vehicle, and relates to the technical field of vehicle parts. The differential mechanism comprises a differential mechanism shell, a planetary gear, a planetary gear shaft and a gear ring. The differential shell is provided with an installation cavity, the planetary gear is installed on the planetary gear shaft and located in the installation cavity, and the two ends of the planetary gear shaft penetrate through the differential shell to be located on the two opposite sides outside the differential shell. The gear ring is annular and provided with an inner hole, the differential mechanism shell is partially located in the inner hole, the gear ring is provided with grooves located in the two radial opposite sides of the inner hole, and the two axial ends of the planetary gear shaft are clamped in the grooves respectively to limit rotation of the planetary gear shaft. The planetary gear shaft is directly connected with the gear ring, in the operation pro
