The invention provides a novel axle housing cushion plate assembly comprising an axle housing cushion plate, an axle housing middle section, a limiting block, bolts and nuts. The axle housing cushion plate comprises a four-tooth-shaped cushion plate base body; circular arc open grooves are formed in the four corners of the bottom face of the cushion plate base body; the bolts each are in a U shape; and the axle housing cushion plate is fixed to the axle housing middle section through matching of the limiting block, the bolts and the nuts. The axle housing cushion plate is in limited connection with the an axle housing by being fastened through the limiting block and the bolts, a traditional welding mode is replaced, axle housing fracturing caused by the concentrated stress of a weld joint formed by welding is avoided, and the reliability of the axle housing is promoted.
