Abstract

In this paper, we present the model in steady state conditions of a planetary traction drive continuously variable transmission (CVT). The model provides the efficiency formulation of the CVT as a function of the geometry and the operative point considering slip and spin losses in the points of contact. The physical behaviour has been studied using the results from the EHL theory. The simulation results of this model show good efficiency performances and a large reduction ratio range.
