The invention discloses a drive axle housing assembly for a low-floor public bus. The drive axle housing assembly comprises an axle housing body, reduction gearboxes are installed at the two ends of the axle housing body, a center hole penetrating through the two ends of the axle housing body is formed in the edge of the axle housing body and used for allowing a half shaft for connecting a main speed reducer assembly with a differential mechanism and the reduction gearboxes to penetrate through in the using process, and a thrust rod base is arranged on the axle housing body. One end of the axle housing body is provided with an installation cavity used for installing a main speed reducer assembly with a differential mechanism, the front portion of the installation cavity protrudes forwardsto form a protruding shell, the protruding shell is communicated with the installation cavity and used for installing a driving gear of the main speed reducer assembly with the differential mechanism,and an observation hole is formed in the top of the protruding shell, and is used for visually inspecting tooth surface meshing marks of a driving gear and a driven gear when a main speed reducer belt differential assembly is installed and inspecting a ruler side gap of the driving gear and the driven gear through a dial indicator. During assembly, the assembly quality can be visually detected, the difficulty of the production and manufacturing process is reduced, and the use and maintenance cost of customers is reduced.
