Abstract: A main frame assembly is for a paving vehicle having an engine and two wheel assemblies, at least one of the wheel assemblies being operably connectable with the engine for mobilizing the vehicle. The frame assembly includes a lower frame having two opposing sides, each side being configured to connect with a separate one of the two drive assemblies, and a mounting portion. An upper frame is connectable, preferably removably connectable, with the lower frame. The upper frame has a compartment configured to receive the engine and an attachment portion, the upper frame attachment portion being connected with the lower frame mounting portion so as to connect the upper and lower frames.

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.
