The embodiment of the invention provides a differential mechanism, a drive axle and a vehicle. The technical problem that the energy recovery efficiency of an electric vehicle is low is solved. The differential mechanism comprises a first drive plate, a gear assembly, a first transmission structure and a second transmission structure. The gear assembly comprises a planetary gear train; the planetary gear train comprises an outer raceway, a planet wheel support and a planetary gear set. The outer raceway and the planet wheel bracket are respectively connected with the planet gear set; the first driving plate is in transmission connection with the outer roller path through a first transmission structure, and the first driving plate can slide relative to the outer roller path; along the axis of the outer roller path, when the first driving plate is located at the first position, the first driving plate is disconnected from the planet wheel bracket; when the first driving plate is located at the second position, the first driving plate is in transmission connection with the planet wheel support through the second transmission structure. By adjusting the transmission connection relation between the first drive plate and the planet wheel support in the gear assembly, the torque amplification function of the differential mechanism can be achieved, the energy recovery efficiency is improved, and then the cruising ability of the electric car is improved.
