  • Patent number: 6247233
    Abstract: A wheel assembly for a work machine, such as a mining dump truck, comprises 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. Related methods are also disclosed.

  • Patent number: 5584773
    Abstract: In the operation of modern day construction machinery, especially those of relatively large size, it is a common occurrence for the bearings in the axle assemblies to wear during the normal course of operation of the machine. As the wear occurs, minute particles become suspended in the fluid circulated within the axle assembly. As the particulate matter increases the wear is also accelerated and failure of one or more components in the axle assembly will frequently occur. The present invention provides an axle assembly with a filter and a cooler and flow control valve to remove the particulate matter and reduce the heat from the fluid circulated within the axle assembly.
