The invention relates to a new-structure high-strength driving axle housing. The axle housing comprises an axle housing body, wherein the axle housing body comprises an axle bag, shaft tubes extending out of the two sides of the axle bag and a triangular plate fixed to the inner layer of the axle bag, and the axle housing body is of an up-and-down and left-and-right symmetry structure and is divided into four symmetric intervals along the up-and-down symmetry axis and the left-and-right symmetry axis of itself; in any symmetric interval, the outline of the outer layer of the section of the axle bag is sequentially composed of a smooth-transition straight line, a first arc, an inclined line and a second arc, and the outer layer of the axle bag stretches in the reverse direction in the second arc area to form at least one spherical protrusion. According to the axle housing, on the premise that bearing capacity is not changed, the overall weight of the axle housing is reduced by 12%, the performance of the product is greatly improved, and great contributions are made for lightweight technological development of the driving axle housing.
