Engineering Design Study for the Adaptation, Assembly, and Installation of a Regenerative Mechanical Differential Steer Unit for Tracked Amphibious Vehicle

摘要

An engineering design study was conducted for the adaptation, assembly and installation of Gleasman Steer Drive (GSD-10) system for the U.S. Marine Corps AAV-7A1 tracked amphibious vehicle. The GSD-10 is an innovative solution to the problem of tracked vehicle steering and is composed primarily of commercially available, off-the-shelf components. Analyses included the collection of relevant commercial drive train component data, steering control system study, weight and balance estimates, and a performance analysis of the proposed system. The final design demonstrates that commercially available components can satisfactorily be employed in the adaptation of the GSD-10 to the AAV-7A1, but the desire to minimize system weight resulted in the integration of the primary and secondary differentials into one housing.
