Abstract
An infinitely variable transmission and system in which power supplied to a system input is transmitted to a system output through at least two infinitely variable (I.V.) transmission units and an epicyclic gear train. The I.V. transmission units are independently adjustable and operable to assure an equal division of power transmitted through each unit over at least the range of systems operation where demand for maximum power is likely to occur in practice. As a result, rated power for each unit may be one-half rated full power for the system, while at the same time providing a wide range of system speed ratios.
