The differential mechanism comprises a half axle gear, a planetary gear and a planetary gear carrier, the half axle gear is meshed with the planetary gear, a first supporting part is arranged outside the meshing position and used for supporting the half axle gear, and a second supporting part is arranged outside the meshing position and used for supporting the planetary gear. The minimum distance between the half axle gear and the center point of the differential mechanism is limited, and the center point of the differential mechanism is the intersection point of the rotation axis of the half axle gear and the rotation axis of the planetary gear. The differential mechanism can bear high-strength alternating load, or the size of the differential mechanism is reduced under the condition that the differential mechanism bears the same alternating load. The invention further provides a novel drive axle comprising the differential mechanism, the rigid half shafts are fixedly connected with the half shaft gears and the hubs to support the differential mechanism, the power of a vehicle is conveyed to the differential mechanism through flexible transmission, and the structure of the drive axle is simplified.
