FIELD: transport engineering.
SUBSTANCE: invention relates to the field of transport engineering. The crankcase of the driving axle of the car, obtained by the method for cast iron, contains a housing for the main gear, a rear cover, a left and right casing, platforms for attaching suspension elements, flanges, and reinforcing ribs, combined in a single casting. The ribs run above and below the crankcase. The lower ribs are located horizontally. The upper reinforcing ribs are made hollow and are located perpendicular to the surface of the upper shelves of the casings, thereby forming a T-shaped structure of the crankcase cross section.
EFFECT: reduction in the weight of the drive axle housing is achieved while maintaining its strength characteristics.
