Investigation of Small Roadwheels for Use on Tracked Vehicles.
Abstract
The feasibility of using small roadwheels for future tracked vehicles was investigated by first analyzing an existing LVTP7 suspension and then designing a small roadwheel and roadarm assembly compatible with the LVTP7 track and suspension. Small roadwheel and roadarm assemblies will later be fabricated and placed on an existing LVTP7 for verification of design assumptions and demonstration of mechanical feasibility. The LVTP7 is an armored assault amphibious full-tracked landing vehicle. The primary benefit from using small roadwheels is a considerable internal volume gain. This internal volume can be employed either to gain buoyancy or to lower the land silhouette by redistributing the internal volume. Although small roadwheels can contribute considerable internal volume gain, they produce an undesirable vehicle vertical spring stiffness-deflection relationship when used solely with torsion bar suspensions. Auxillary bump springs or a hydropneumatic suspension would be needed to stiffen the suspension against vertical deflections above static and produce a more desirable spring stiffness-deflection relationship.
