ABSTRACT:
A wheel assembly for a work machine, such as a mining dump truck, having a rotatable wheel having inboard and outboard rims mounted thereto. The outboard rim is mounted to a segmented rim-mounting flange which is secured to the inboard side of a flange projecting from the wheel. A final drive adapter is secured to the outboard end of the wheel opposite the segmented rim mounted flange. The segmented mounting flange permits the use of a larger final drive ring gear than in known wheel assemblies. Moreover, because the mounting flange is segmented, it can be fastened to the wheel inboard of the gear reduction housing, which permits the final drive assembly to be serviced without removal of the outboard rim from the wheel.
