In this work the performances of an infinitely variable transmissions (IVT), or rather a split-power CVT System with a infinite ratio range, are appraised. The experimental results reported in this work are obtained through a special test rig, in which a IVT prototype was reproduced by joining a V-belt CVT, a planetary gear train, and a fixed ratio transmission. The IVT has a parallel connection and a type 11 power flow. Considering the output torque and transmission ratio variation, the input, output, and the circulating CVT powers are measured. The performances in terms of torque, power, and IVT efficiency are compared with those of a traditional CVT. The experimental results are compared with those obtained through a theoretical model. The performances of a series-IVT with flow type I are finally compared with those of a parallel-IVT with flow type II.
