摘要
An infinitely variable transmission (IVT) is a continuously variable transmission with an infinite ratio range, which means that the transmission ratio may achieve zero. This paper compares the efficiency of possible IVT configurations consisting of a conventional CVT (continuously variable transmission) coupled to a planetary gear train and a fixed ratio mechanism. A kinematic analysis has been performed to determine the transmission ratio of the IVT components for two types of power flow. The efficiency of the IVT has been determined considering how the efficiency of the IVT members changes as a function of the operating conditions. The power and efficiency curves for the different functional solutions have been compared. (C) 1999 Elsevier Science Ltd. All rights reserved.
