The invention discloses an automotive rear axle shell, and relates to the technical field of automobile manufacturing. The automotive rear axle shell comprises an upper half shell and a lower half shell, wherein the upper half shell and the lower half shell are welded in a butt-joint mode to be the hollow rear axle shell; a steel plate spring seat is arranged outside the upper half shell; the two ends of the rear axle shell extend in the axial direction, and the extending sections are cylindrical pipe sections with the diameter smaller than that of the cross section of the rear axle shell; the cylindrical pipe sections and the rear axle shell are in arc transition; the outer end surfaces of the cylindrical pipe sections are connected with small round rings; brake shoulders are connected with the position, near arc transition, of the outer surface of the rear axle shell; a plurality of protruding arc outer reinforcing ribs are arranged on the wall of the rear axle shell in the axial direction, and batten-shaped inner reinforcing ribs are arranged on the inner wall of the rear axle shell in the axial direction.
