Abstract
A rotary union is integrated into the interior of a heavy-duty vehicle hub cap. The hub cap includes a cylindrical sidewall, and an outboard wall that is integrally formed with an outboard end of the sidewall, and which extends generally perpendicular to the sidewall. The hub cap also includes a radially-extending flange that is formed on an inboard end of the sidewall, which receives fasteners to mount the hub cap on a wheel hub. The sidewall and the outboard wall form an interior compartment in the hub cap, and a rotary union is mounted to the hub cap in the interior compartment. The rotary union is mounted on the inboard surface of the outboard wall of the hub cap and is in general axial alignment with an axial centerline of a wheel end assembly, providing fluid communication from a tire inflation system to the tires of the vehicle.
