Orbital IVT for High efficiency torque multiplication for military ground vehicle transmission

The patented Lestran L.L.C. Orbital IVT is a novel automotive transmission design that harnesses the power from the centrifugal force of rotating eccentric masses to create the first Infinitely Variable Transmission (IVT) capable of scaling to large vehicle sizes. The unique design combines the high mechanical efficiency of fixed gear ratio transmissions with the high engine efficiency obtained using a Continuously Variable Transmission (CVT) in a lightweight, rugged, and high-torque package.The simple, high-efficiency design of the Lestran Orbital IVT allows the components to be sized for greater endurance and higher power while remaining smaller than competing designs. The high mechanical efficiency of the Orbital IVT eliminates hydraulic fluids and costly lubrication and cooling methods resulting in a dramatically higher maintainability and lower operating cost. The small number of parts and the straightforward parts design drive reduced manufacturing costs in both material and labor and increase reliability.The Phase I project will develop a preliminary design for a target military vehicle, validate existing physics based models, and take test data to verify major performance and efficiency claims.
