The invention relates to the technical field of vehicles, and discloses a differential mechanism assembly, a speed reducer assembly, a driving motor assembly and a vehicle, the differential mechanism assembly comprises a gear disc, the peripheral edge of the gear disc is provided with gear teeth, and the gear disc is used for being in meshed connection with an intermediate shaft of a speed reducer; the guide structure is coaxially arranged on the inner circumferential side of the gear disc, a through hole allowing the half shaft to penetrate through is formed in the middle of the guide structure, and an elastic assembly is connected between the guide structure and the gear disc; the differential case is arranged on one side of the gear disc, and the differential case is connected with the guide structure; and the differential gear set is mounted in the differential shell. The elastic damping system composed of the guide structure and the elastic assembly is integrated in the differential assembly, the phenomenon that the rotating speeds of wheels or a motor are not synchronous due to rotating speed fluctuation of the wheels or the motor can be avoided, rigid vibration in the power transmission process is filtered and absorbed, and the stability of a motor driving system is improved.
