ABSTRACT:
A belted undercarriage assembly for a vehicle, such as a non-powered towed trailer, includes first and second endless belt assemblies, one positioned on each side of the vehicle, first and second wheel supporting frame assemblies associated respectively with the first and second belt assemblies, and a supporting axle connected to each of the frame assemblies and to the vehicle. Each of the frame assemblies includes first and second rectangular shaped tubes which are adapted to telescope together. A first threaded adjusting mechanism controls the telescopic relationship of the first and second tubes and a second threaded adjusting mechanism controls lateral movement of the first tube relative to the second tube. Providing proper belt tension and alignment of the belt on the guide wheels are important to efficient and economical operation of a belted undercarriage assembly. If proper tension is not maintained, or if the belt drifts to one side or the other, undesirable heat buildup and wear are produced. The subject belted undercarriage incorporates simple and economical apparatus and methods for controlling the tension and lateral movement of the belt.
