The invention discloses a rear axle wheel difference structure, which relates to the technical field of automobile parts and comprises a reducer shell, a meshing sleeve and a shifting fork, a shifting fork shaft is arranged in a working cavity of the reducer shell, and a compression spring is arranged at the tail end of the shifting fork shaft. The upper end of the shifting fork extends into the working cavity and is connected with the shifting fork shaft; the lower end of the shifting fork is connected with the meshing sleeve; a cover plate is further included. A guide channel is horizontally arranged on the outer side wall of the working cavity; the head end of the shifting fork shaft is provided with a piston part matched with the guide channel, and the piston part can reciprocate in the guide channel; an annular groove is formed in the outer circle face of the piston part, and an O-shaped ring is installed in the annular groove. The cover plate is fixedly connected with the reducer shell and used for sealing the guide channel. A gas guide hole communicated with the guide channel is formed in the middle of the cover plate and is used for introducing gas into the guide channel to push the piston part to move; and the disengagement gap between the meshing sleeve and the tooth surface of the differential mechanism is 5-7mm.
