The invention relates to a wheel edge device of a semi-floating rear drive axle assembly. The wheel edge device comprises a half shaft (1), wherein a brake drum (11) is connected to the outer side of the half shaft in a matched mode, and a brake (10) is connected to the brake drum in a matched mode. The wheel edge device is characterized in that the half shaft is sleeved with a transition receiving disk (2) in a matched mode, and a bearing (5) connected with the half shaft (1) in a matched mode is arranged in the transition receiving disk; the transition receiving disk is further matched with the brake in a braking mode, a bearing baffle (8) is arranged on one side of the transition receiving disk, and a bearing locating sleeve (12) is arranged on the other side of the transition receiving disk; the bearing baffle and the bearing locating sleeve are both matched with the bearing in a limited mode and are both connected to the half shaft in a sleeving mode. The wheel edge device has the advantages that a bearing seat, an axle housing oil seal and a half shaft oil seal of an existing wheel edge device are omitted, the number of parts of the wheel edge device is reduced, the raw material cost is lowered, and the structure is compacter, so that the total weight of the rear drive axle assembly is lowered by 4%; the assembly process is simplified, and production efficiency is improved.
