ABSTRACT:
A track roller frame assembly is connected to the main frame of a vehicle such as a combine harvester or the like, and is adapted to drive an elastomeric drive belt. An elongate track roller frame thereof includes a main body, pivot means on the main body for pivotal connection to the main frame, a supporting collar connected to the main body, and a plurality of roller wheels underlyingly connected to the main body. A wheel includes a housing encirclingly supported by the collar away from the pivot means, a shaft assembly rotatably supported within the housing, and inner and outer wheel portions connected to the opposite ends of the shaft assembly. A hydraulic drive motor within the housing rotates the shaft assembly and the wheel portions and drives the elastomeric drive belt. The drive motor is protectively located between the wheel portions, and the lightweight construction features the symmetrical transmission of belt forces and torque loads through the housing and into the supporting collar along the central plane of the track roller frame.
