  • Mobile construction vehicle driven by track assemblies using continuous elastomeric belts
    Patent number: 6047785
    Abstract: A paving machine that is driven by track assemblies utilizing continuous rubber belts uses a motor and planetary gear reduction combination on each drive wheel to drive each belt. Each planetary gear includes a planetary joint connection between a rotating and a non-rotating portion, with an elastomeric seal therein to retain lubricating fluid in the planetary housing. Each drive wheel is formed from a pair of annular ring members rigidly connected together and spaced apart to provide a passage for directing debris falling from a rotating drive wheel away from the planetary joint, to minimize damage to the seal.
    Type: Grant
    Filed: April 2, 1998
