Transmission search

IAV has developed a computerized tool set for the selection of automatic transmission gearing arrangements. The program systematically searches through all power flow permutations for a specific application and then selects the architecture with the highest mechanical efficiency and the lowest number of loaded components. Searches can be performed for both conventional planetary and dual-clutch lay shaft structures. As transmissions tend toward larger ratio ranges with more gears to lower fuel consumption, units need to incorporate lower weight and cost, hybridization, smaller packages, and good shift quality. A manual search for transmission architectures cannot always deal with complex requirements; however, with the IAV transmission structure search process, first, application parameters are established; second, all possible transmission variants are generated; and third, selection and ranking criteria are used to narrow the set of transmission concepts down to candidates with favorable properties.
