ABSTRACT: With their advantages, continuously variable transmissions have gained
more popularity in the last decade by their use in mechanical transmission systems.
The present paper aims to analysis the efficiency of the transmission based on the
mechanical efficiency of the planetary gear train integrated in such transmission.
In this analysis, we consider the mechanical efficiency of the transmission has
been determined considering how the efficiency of the CVT members changes as a function
of the operating conditions. The efficiency of the planetary gear train as a function
of the configuration, speeds in his three input/output shafts, and also
with respect to the power flow type. Results are compared with those obtained from
other methods performance evaluation of the transmission, available in the literature.
