Abstract

A drive axle assembly for a heavy goods vehicle includes a hollow hub, a wheel body rotatably mounted to the hollow hub, and a planetary gear including first and second planetary gear stages, each having a sun gear, a ring gear and a planet carrier with planetary wheels mounted rotatably in the planetary carrier and meshing with the sun gear and the ring gear. A drive shaft is axially guided through the hollow hub and the sun gear of the second planetary gear stage, with the sun gear of the first planetary gear stage being non-rotatably mounted on a vehicle-distal outer end of the drive shaft. Non-rotatably connected by a screw and pin connection to the hollow hub is an annular disk which has an axial opening and a plurality of boreholes in radially surrounding relationship to the axial opening.
